Question

What are the classifications of the die?

Answer
Laser die; aluminum die; engraving die; etching die; wood laser die; die material; die die equipment; die cutter die; electronic laser die; rubber plate laser die; FPC laser die, stripping die
 
Electronic materials, printing and packaging, plastic packaging, leather, toys, automobiles, decoration, rubber products, EVA and various foams, precision electronic gaskets, Mylar sheets, nameplates, flexible circuit boards, etc.
The traditional die-cutting method is drawn with a pencil or a ballpoint pen on the knife template, and then sawn by a sawing saw. During the moving process, a misalignment is generated and an error occurs; the processing speed is slow; and after the laser cutting machine is used, the drawing design is It can be directly carried on the computer. The knife template is fully automatic and cut by the laser cutting machine without manual intervention. The error is small and the speed is fast. The application of the laser die cutting machine can significantly accelerate the development of the enterprise and improve economic efficiency.
The working process of the laser die is: Firstly, in the AUTOCAD or impact or other software developed for the die, the die that needs to be produced is designed, processed according to the actual situation, and then stored as the file format accepted by the corresponding machine, then the device can be started. Perform template processing. After the completion, the die-cutting cutter line is installed to form a finished cutter.
Computer bending machine and computer cutting machine
Nowadays, the development of the die cutter is not only the credit of the laser cutting machine. In the past few years, various computer bending machines and cutting machines have entered the market, bringing unlimited convenience to the die making, improving work efficiency and reducing The bending tool forming error can be regarded as the development of the die with the merits of these devices.
Computer equipment and traditional hand-made, although the computer bending machine can not fully realize the shape of the doll 100% bend in place, but the straight shape in the simple shape and straight knife cutting precision is extremely high. Effectively accelerate production efficiency. There are computer equipment combined with manual production, which is basically more than double the speed of pure manual.
Question

What is a die? What is the use of a die?

Answer
First, the origin and definition of the mold
Origin: When the mold originated, it has not been verified. In the Stone Age, more than two million years ago, it is said that human beings know that making molds is not practical. Because human beings at that time were mainly based on survival, there was no time or energy to think about things other than survival. The Stone Age is an era dominated by stone equipment. Of course, people also use wood, bamboo and bone as devices to engage in production activities.
Definition: Various molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, drawing, etc. to obtain the desired product. In short, a mold is a tool for forming an article, and the tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. This special tool is collectively referred to as a mold.
 
Second, the definition and development of stamping die
China's archaeological discovery, as early as more than 2,000 years ago, China's existing stamping dies were used to manufacture bronzes, which proved that the achievements of ancient Chinese stamping and stamping dies were leading in the world. In 1953, Changchun First Automobile Manufacturing Co., Ltd. established the first die shop in China. In 1958, the factory began to manufacture automotive cover molds. China began to produce fine-punching molds in the 1960s. After a long and arduous development path, China has formed more than 30 billion yuan (excluding the statistics of Hong Kong, Macao and Taiwan, the same below.) The production capacity of various stamping dies. With the development of computer technology, computers have gradually entered various fields of mold production, including design, manufacturing, and management. The International Association for Production Research predicts that by 2000, drawings that are the means of communication between design and manufacturing will lose their primary role. The most fundamental point in the automatic design of molds is the need to establish mold part standards and design standards. In order to get rid of the design method that was centered on people's thinking judgments and practical experience, it is necessary to serialize, digitize, and digitize past experiences and methods of thinking, and store them in the computer as design criteria. Because the mold components are also different, it is almost impossible to create a design software that can adapt to various parts.
 
Compared with the traditional die-cutting process
The traditional die-cutting method is drawn with a pencil or a ballpoint pen on the knife template, and then sawn by a sawing saw, and a misalignment occurs during the moving process, which causes an error; the processing speed is slow;
After using the laser cutting machine, the drawing design can be directly carried out on the computer. The knife template is fully automated and cut by the laser cutting machine without manual intervention. The error is small and the speed is fast. The application of the laser die cutting machine can significantly accelerate the development of the enterprise and improve economic efficiency.

Hardware mold
 
The metal mold is used in industrial production, using various presses and special tools mounted on the press to produce metal parts of the desired shape or parts by pressure. This special tool is collectively called metal mold.
Metal molds can be classified according to various processes: punching die, bending die, drawing die, forming die
Other combination modes: single-process mode, composite mode, progressive mode (also called continuous mode), multi-station mode
 
Blanking die A separate mold, such as blanking die, punching die, cutting die, slit die, trimming die, cutting die, etc., along a closed or open contour.
Bending Mold A mold that bends a sheet blank or other blank along a straight line (curved line) to obtain a workpiece of a certain angle and shape.
The drawing die is a die in which the blank of the sheet is made into an open hollow member, or the hollow member is further changed in shape and size.
The forming die is a mold in which the blank or the semi-finished workpiece is directly copied and formed in the shape of the convex and concave molds, and the material itself only produces a partial plastic deformation. Such as bulging die, shrinking die, flaring die, undulating forming die, flanging die, shaping die, etc.
Single-step mold In the one stroke of the press, only one mold for the stamping process is completed.
Composite mold There is only one station, in the first stroke of the press, two or more stamping processes are completed simultaneously at the same station.
The progressive die press adopts the strip-shaped stamping raw material in one press stroke, and simultaneously completes the cold stamping die of multiple stamping processes on several pairs of molds on one pair of molds. Move once to the completion of the product.
In the multi-station die, the material strip always moves in one direction during the stamping process; the inner strip of the mold is cut into two or more directions and is called the progressive die; the feeding of the strip in the mold is called the automatic continuous die. In a stamping production chain, a stamping die with different processes is used with a robot or other automated facility, and the die or part moving is used to complete the workpiece stamping process. The rated die is called a multi-station die.
 
Metal molds and stampings
 
 
 
QDC composite mode
 
The QDC module adopts the combination of modules, and is mounted into the metal die holder by using a carving die or a corrosion die, for punching and stripping; because the die can be replaced according to different die cutting needs, taking into account the die cutter Advantages and precision and stability of the die can also be stamped according to the needs of die cutting. The tolerance of the two sets of holes can reach 0.05mm.
Mainly used to produce some products that are complicated in process and difficult to discharge.
Die cutting life can be repeated
 
QDC composite mode
 
 
 
Round knife roller mold, bronzing film, concave and convex mold
 
 
 
How to choose the angle of the die cutter according to the die cutting material
 
First, ordinary cardboard ordinary cardboard includes common cardboard, corrugated paper and so on. Die-cutting This type of paperboard can be selected from ordinary laser knives (edge ​​angle 52o). If the die-cutting shape is complicated, it is necessary to select a tool with a slightly lower hardness and a better bending machine. In the die cutting process, if the die cutting pressure is required to be small, a blade having a blade angle of 42 o can be selected. Small die cutting pressure reduces blade wear and extends die cutting life
Second, rigid rubber sheet hard rubber sheet includes PVC, PET, electronic board, high-density materials, gaskets and so on. Molding of such materials requires the use of a high hardness tool. The ordinary laser cutter has a hardness of 39HRC and a blade hardness of 57HRC. If the die is hard-cut, it needs to use a blade with a hardness of 47HRC and a blade hardness of 59HRC. The smaller the blade angle, the greater the blade hardness, the better the wear resistance.
three. Flexible material flexible materials include aluminum foil, peritoneal material, soft plastic and so on. For die-cutting such materials, it is necessary to use a finely ground blade with a sharp edge. This type of blade has a smooth blade surface, requires less die-cutting pressure, can pass through the viscous material, and reduces the problem of brushing and fluffing.
four. Recycled paper die-cut recycled paper is very easy to produce paper powder, so choose a tool that can reduce the friction between the blade and the paper during die cutting. The blade surface is polished or coated to be very smooth and can meet this requirement; if the edge angle reaches 42o, the die cutting pressure can be further reduced, so that the die cutting dust reaches at least
 
Fourth, mold use specifications
Use
Receive the corresponding mold according to the number on the processing instruction sheet
Must be registered on the "Mold and Fixtures" when you use it.
Check if there is a knife bag / die mark / with or without a sponge
Whether the die is qualified or not, if it is found that there is a problem with the die, it must be reported to the boss in time, and it cannot be handled privately, or it can be used to produce it!
 
return
The die that has been produced by the machine must be placed in the corresponding die pocket and placed in a uniform area.
The original employer must return the mold to the mold rack and register
If there is a problem with the die, the machine personnel must report the boss immediately and indicate where the die problem is indicated on the die.
The machine personnel must find out the cause of the bad die, so as to deal with it in time to prevent similar events from happening again.
 
Molding and demoulding
The die-cutting tool holder must be inserted in and out at the flat end, so that it cannot be tilted to avoid collision.
When disassembling the mold, take care of the knife and do not hit the knife.
 
Precautions
When handling the die problem, the tool should be careful not to hit the knife.
Do not place metal tools on the dies of the die-cutting machine to avoid falling.
 
 
 
Sponge selection
 
PC products
High elasticity of sponge
Sponge height requirement is 0.5mm higher than the blade
Must trim the sponge according to different printing requirements
Paper products
The elastic strength of sponge is not high
Sponge height requirements are higher than
Blade 1—1.5mm
Properly trim the sponge according to the requirements of the print
 
 
 
Mold maintenance
 
1. Mold maintenance and maintenance when taking over or returning the mold
2. If you need to change the mold during production, you should not put the mold randomly. It must be placed on the countertop without other iron and other materials, and the knife edge must be placed face down or a protective plate should be placed on the knife edge to prevent it. Other objects fall and damage the tool
3. In the production process, if there is a broken joint at the joint of the mold knife, it must be cleaned in time to prevent the knife edge from opening and affecting the production.
4. Spray the rust inhibitor on the mold that is not commonly used to prevent the tool from rusting.
 
Five, the common die is abnormal --- knife edge
 
cause
The blade interface is not received
Blade offset at the interface
Approach
The blade is not connected --- can be tapped at the ends of the blade towards the middle
The interface is not connected properly - you can use the needle-nosed pliers to gently clip the offset blade
Precautions
Do not operate without professional
Try not to touch other blades during operation
 
 
 
Common die abnormalities --- gap
 
cause
The blade is bruised during circulation
The blade is improperly handled during use.
Approach
Use a utility blade to gently wipe the sides of the blade, not too hard. Until the blade is not abnormal
Precautions
Depending on the severity of the gap, if it is too serious, it must be replaced.
Moderate, not too hard
Special reminder that paper prints must increase the inspection frequency after scraping the blade

Question

Laser cutting machine common faults and solutions

Answer
Laser cutting machine often fails during use. Without the guidance of professional staff, it is difficult to accurately judge the source of the laser cutting equipment. It can only be explored based on its own experience, but some faults will appear for the first time. We will be a little helpless. Even after consulting the factory, there is no way to describe it clearly. The Han's super-energy laser has carefully selected some laser cutting machine faults and corresponding fault sources or solutions.
 
1 Is the cutting effect not good or not worn?
 
The power setting is too small, the potentiometer is small, the light is polarized, the lens is dirty, the focusing lens is reversed, the focal length, the laser power supply, the laser tube power attenuation, the water temperature is too high, the voltage is unstable, etc., according to the actual situation, it is as simple as possible.
 
2 Can't connect to the device?
 
Whether to install the board driver, whether the USB cable or network cable is plugged in, the USB cable or network cable is bad, the adapter board is bad, the board is, etc.
 
3 Turn back to the original point and move in the opposite direction?
 
Origin switch is broken
 
4 Cutting pattern deformation and cutting overlap?
 
Synchronous wheel screw loose, motor line broken, motor broken, driver, voltage, etc.
 
5 The device can't be started and the boot room is tripped when it is open.
 
Whether the emergency stop is bounced, whether the external circuit is connected, whether the internal opening of the device is closed, whether it is turned on or not, please check the main contactor and the control transformer, etc.; the water protection leakage causes the laser power supply to short-circuit into the water ( For example, the JGHY12570 water protection position is installed on the side, it is just the laser power supply underneath, the 107 water pump is short-circuited, the indoor air is used too small, etc.
 
6 High-voltage line fire?
 
This problem is really a headache. I suggest putting a high-voltage insulating sleeve on the outside of the high-voltage line.
 
7 Is the graphic size too large or too small?
 
Whether the output graphic size is the same, the Z-axis height position changes, the correction file, etc.
 
8 The color of the image that is printed is different from the surrounding color?
 
Adjust the focus factor, adjust the W-axis focus, etc.
 
9 Is there a bad phenomenon and a thick spot in the marking process?
 
Dynamic, DA board, etc.
 
10 Marking graphic position offset?
 
The X-axis or Y-axis position of the vibration lens is offset, and the center point is found. The XY axis position is adjusted according to the actual offset direction.
 
11 Start-up vibration lens XY axis chaos and dynamic motor abnormal noise swing?
 
Replace ±12±15V switching power supply; replace ±12±28V switching power supply
 
12 No light?
 
Whether the chiller return water is normal, whether the W-axis position changes, whether the DC48V32A laser power supply is normal, laser tube, etc.
 
13 The boot display panel has no display?
 
5V12V24V switching power supply is normal, display panel, etc.
 
14 Does the UPS return to the original display panel fail?
 
Replace offline card
 
15 Z axis does not feed or exercise is weak?
 
Z-axis feed motor problem, drive problem, bearing, foreign matter stuck, etc.
 
16 Glass tube does not emit light?
 
The light control of the glass tube mainly includes a laser tube, a laser power source, a water circulation system and an light output signal, and the light output signal includes a PWM light output signal given by the board, a water protection signal, a door switch signal, and the like. Therefore, the laser tube does not emit light mainly from the laser tube laser power water circulation system and the light output signal. Generally, firstly, whether the laser power supply is normally energized, whether the outer tube of the laser tube is abnormal, whether the water circulation system is normal, if not normal Make the appropriate replacement or adjustment. In the normal situation of the above aspects, the optical signal problem should be considered. Generally, the short-circuit signal (short-circuit laser power supply current 5v and AIN short-circuit water protection P and GND with lock-free switch control L and GND) is used. Test laser tubes and laser power supplies. If this method can emit light normally, it means that the laser tube laser power supply has no fault, and it is a signal problem of water protection switch, relay, door switch, board pwm signal, etc., and can be eliminated in order. If this method does not emit light, it is a problem of laser tube or laser power supply, and it can be solved by the replacement method in case of bad judgment.
 
17 RF laser tube does not emit light?
 
In the case that the waterway unobstructed laser power supply is normally started, it is first tested whether the laser power supply DC 48v is normal; the conduction of the 4 pin and the 13 pin of the 25-pin plug of the laser tube can be turned on to indicate that the water protection signal is normal, and the water protection cannot be turned on; The voltage conditions of the 7-pin and 20-pin are not pre-adjusted or the DC voltage is about 4 to 5V at the beginning, and the normal signal (low-level conduction) is pre-adjusted or started at around 1 to 3v. If the water, power supply and these two signals are normal, it can be judged that the laser tube is faulty. If the signal is not normal, it indicates a board problem or a circuit problem.
 
18 After the replacement of the RF laser tube, the laser tube connection error is displayed?
 
In the connector (internal line is not desoldered short circuit), the power line (left and right negative and negative poles are connected with the ground wire), the water connection is normal. After restarting the chiller and the device, the 25-pin connector is generally not connected. The problem of connecting the board is broken or not compatible, such as the encrypted tube and the non-encrypted tube, the board is not compatible
 
19 The cutting machine is misplaced?
 
(Cut heavy or collinear graphics cut too far) "
 
1.) Feeding cutting misalignment First, the step distance of the feeding shaft = measured length * original step / real length (set feeding length) 2 is to check the timing belt of the feeding shaft with the locking wheel and the motor timing belt locking wheel Whether it is loose or not, there is a relative sliding between the rolling net and the feeding shaft, and whether there is a carding phenomenon.
 
2.) Unfeeding cutting misalignment First, the car motor or the optical axis synchronous wheel is loose. The second is the lost step. The lost step may be the machining speed. The idle speed or the acceleration setting may be too large. If the current is too small, the driver may be broken or the motor may be broken. Generally, the motor is bad and the lost step is less.
 
20 Feeder feed?
 
The feed length of the feeder is generally the photoelectric switch is bad or the light sensitivity of the photoelectric switch is not adjustable. The sensitivity of the photoelectric switch of the feeder is adjustable. When the upper and lower switches are connected at the same time, the feeder starts to work when the light sensitivity is too high. When sensitive, even if there is cutting material blocking, it will be inductive, so it will be long. At this time, adjust the sensitivity adjustment knob of the photoelectric switch wiring to adjust the light of the photoelectric switch when the material is blocked.
 
21 Is the galvanometer machine too thick?
 
The light intensity is not enough. The light path of the basic light path and the over-expanded beam is well adjusted. When the dynamic focus is well adjusted, the spot is still relatively thick. It is necessary to adjust the distance between the two lenses of the beam expander. Generally, the three-fold beam expander commonly used by our company is adjusted to expand the beam. The mirror spot diameter is 13-14mm, and the effect can be adjusted according to the customer's processing requirements.
 
22 galvanometer machine dynamic self-excitation?
 
Dynamic whistling for Shanghai dynamics is to adjust R103 R28 to adjust the self-excitation and howling adjustment is invalid. To measure whether the motor shaft is short-circuited with the casing, the power cord of the motor should be disconnected during measurement, otherwise it is long-conducting. If the power line measurement is still on, the motor and the case should be well insulated with insulating film and then adjusted. R103 R28 can be processed and replaced.
 
23 Marking machine and cutting machine marking or cutting size is wrong?
 
For the dynamic marking machine, when the vibration lens is not moving up and down, the size is not correct. Generally, the correction parameter data is changed or the error is corrected. The parameter correction of the galvanometer can be solved. The cutting size of the cutting machine is generally not the step size and the number of pulses of the driver. The general determination of the number of pulses caused by mistakes can be solved by calculating the step size.
 
24 Is the cutting machine turned back to the origin direction?
 
Such faults are generally caused by the origin switch being broken. The origin switch has a proximity switch and a mutual switch (magneto-switch). The two return-to-origin directions are generally caused by the short-circuit of the switch coil.
 
25 Power supply DC switching power supply failure of the cutting machine motor, motor drive, motor line and driver?
 
The specific manifestation of such failures on the equipment is generally
 
(1) The laser head does not move
 
(2) The abnormal operation of the laser head during operation is stagnation and jitter, etc. Generally, such a situation is first observed. Whether the DC switching power supply of 48v or 42v is working properly. The power supply voltage is insufficient or unstable. If the switching power supply works normally, It is necessary to consider whether the motor or the motor line is faulty. First, the motor should first observe whether the rotation of the motor itself is smooth when the motor line is disconnected from the driver. If the motor rotates differently, it can be directly judged as the motor failure. If the motor itself is running normally, measure the motor coil. For the six-wire motor, AC, A+, A- are a group of coils ac and a+ a- respectively turn on bc b+ b- as a group of coils, conduction If the conduction is not normal, it can be directly judged as a motor failure. For the stepping driver of Baishan and YAKO, if the DC power supply is normal and the motor line is disconnected, if the indicator light of the driver is not bright, the driver is directly judged to be faulty. Can not be directly judged can be tested by the replacement method; in such failures, the motor line failure is a small probability failure, and the motor and the drive are excluded. To consider the case where the motor wires, a short-circuit and detecting whether the open-circuit, with a multimeter detailed investigation of the measurements can be off.

(If the two shafts are not moving during machining, the hand can also be pushed at the time of starting, and the driver light is not bright, indicating that the 42V light-opening power supply is broken).
 
38 Will it jump in one direction when cutting?
 
Increasing the drive current may also be a problem with the drive being broken and the motor line.
 
39 Is the saw toothed?
 
Slider problem
 
40 cutting constantly?
 
The laser tube may be weak; the light path may be biased; it may also be a laser power source.
 
41 Laser head collision can not be restricted?
 
The home switch is broken, or it may not be set on the panel.
 
42 Cutting is not sealed?
 
Belt adjustment and parameter setting
 
43 Is the machine's cutting machine preset with light processing?
 
Generally control card problem
 
44 The size of the cut is inconsistent?
 
Wheelbase and pulse are not adjusted well
 
45 When working, a complete curve has a small distance to jump over without cutting, also known as jumping light?
 
This kind of problem is generally caused by the looseness of the big car slider in the case of long-term high-speed operation. It only needs to re-adjust the sliders on both sides of the cart to solve it.
 
46 When working, some places in the same edition cut and cut some places?
 
This kind of problem is generally caused by light deviation or uneven work surface, which requires dimming and adjusting the platform surface. Sometimes the light deviation is caused by the deformation of the guide rail, and it is necessary to adjust the guide rail.
 
47 When cutting, the two ends are sometimes cut into each other, sometimes separated?
 
This problem is generally caused by loosening of the fixed wheel fixing screws or motor wires. If there is a problem with the motor wires, it is best to replace them all. Do not change one or two separately.
 
48 Summer chillers are easy to alarm at high temperatures?
 
This problem is generally caused by too hot weather, poor cooling of the chiller or insufficient cooling capacity. There is no problem of insufficient cooling capacity from the refrigerating water machine. Generally, the heat sink is too dirty and the ventilating part is good to cause an alarm. Small chillers generally have insufficient cooling capacity, and the temperature difference can be increased, and the alarm temperature is appropriately adjusted to solve the problem.
 
49 hours when there is no light?
 
First, the signal temperature is unstable, including the light signal and the chiller signal, and then see if the potentiometer has poor contact, and finally check if the power supply is bad.
 
50 Boot car does not return to the original point, can't move?
 
This problem is generally that the car motor is not powered, and the laser head can be easily pushed by hand when the device is turned on. The cause of the failure is that the 48V open source power supply is broken, or self-protected. It can be turned off for ten minutes and then turned on. If it is not good, then change the 48V switching power supply.
 
51 After a few minutes, the light from the laser tube becomes weak.
 
There are generally three possibilities for this problem. The power supply has a problem, the laser tube is broken, and the frequency of the laser tube in the software is incorrect.
 
52 When the cart moves, it often shakes sharply?
 
This problem is generally caused by the servo limit line or the limit, and the line change or limit can be solved.
 
53 Two laser heads move around?
 
Generally, the board is bad and the signal given is incorrect.
 
54 Sometimes it is required that the two versions of the graphics can be docked, but can't be picked up when cut out?
 
This problem is caused by the fact that the feed drive shaft and the aluminum pass of the trolley are not parallel, and the trolley cannot be adjusted. Only by adjusting the feed drive shaft to solve the problem.
 
55 Cut with serrations?
 
The sealing slider is loose. The belt is loose, the belt synchronous wheel is eccentric, the curvature value is too large, the corner speed is fast, and the lens is not tight...
 
56 Laser tube power is unstable and the engraving is very good. After a few days, the carving is not the same.
