1. Before planning the strip, it is necessary to understand the public service requirements of the parts, data performance, punch tonnage, punch table, SPM (per minute punch), feeding direction, feeding height, mold thickness requirements, data utilization, mold application life. 2. When planning the strip, it is necessary to carry out CAE analysis together, and the primary consideration is the thinning rate of the data, which is generally below 25{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030}. Special deep-drawn stainless steel data can be annealed after pre-stretching. With high-frequency annealing machine, the thinning rate can be accepted to 40{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030}. It is very important in the specification. When the length of the mold is fixed, it must be Customers need to communicate more, it is best to ask the customer to supply the previous mold photos or structure drawings to refer to, in the case of empty steps, the appropriate space to leave the mold assistance after the test is very large. 3. Material planning is the analysis of the molding process of the product, which basically determines whether the mold is successful. 4. When planning the continuous mold, the lifting plan is very important. If the lifting rod can’t raise the whole belt, it can’t be automated. 5. In the mold planning, the selection and heat treatment of the mold materials and the surface treatment (such as TD, TICN, TD demand 3-4 days), especially the tensile parts, if there is no TD, the mold appearance will be very simple to pull the hair . 6. In the mold planning, as for the hole or the smaller requirements of the public service, the adjustable inserts should be made as much as possible, so that it can be adjusted during the test and production, so that the size can be easily reached. Make adjustable inserts. Regarding the word 唛, it is required to be detachable on the punching machine, and it is not necessary to dismantle the lower mold and waste the time. 7. When planning the hydrogen spring, plan according to the pressure of CAE analysis, do not plan too large hydrogen spring to prevent the product from breaking. The general situation is: the pressure is small, the product is wrinkled, the pressure is high, and the product breaks. To handle the wrinkling of the product, it is possible to use a method of locally adding a drawbead, first fixing the sheet with a drawbead and then stretching to reduce wrinkles. 8. When the first test is performed, the upper mold must be slowly combined. When there is a stretching process, the thickness of the fuse must be used. After the material gap reaches the thickness of the material, the mold must be tested. Right. Use the movable inserts for the drawbeads to adjust the height of the drawbeads. 9. When testing the mold, the reference hole and the reference surface must be placed on the inspection tool after the mold is assembled, or sent to the CMM for 3D report, otherwise it does not make sense. 10, red Dan must be equipped, the fit rate of more than 80{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030}, can open the cut, do CMM report, perhaps the reference hole reference surface has been well-equipped, the product is very stable, the fit rate can be properly reduced. Matching red dan is a very important matter, otherwise the product is unstable and cannot be modified later, and the part scale will not meet the customer’s requirements. 11, customer sample requirements: generally first laser office → cut office → 100{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030} OK office, in the laser stage, red Dan will be well equipped, feed adjustment, deal with cracks, scales, public service problems, open cut Basically, the first problem is changed when the mouth is done, followed by fine-tuning (partial improvement of the mold). 12. In the case that the customer must cut the mouth but the process conditions are not mature, it can be considered to open the soft knife edge (that is, directly use 45 steel to open the knife edge, directly cut the welding when the cut is made, and then open the official hard material after the scale is OK. blade). 13. Regarding 3D messy products, you can use 3D laser to laser. Before 3D laser, you must make 3D graphics. After using CNC to set the reference point, send 3D laser. 3D laser still needs to be positioned. 14. For high-strength steel plates, the cutting edge data should use hard alloy materials such as A88 or V4. 15. In the trial mode, for the trial stretching effect, it is possible to test the sandpaper in different directions on the data to determine the action of the drawbead or the active hemp matrix in the corresponding orientation (that is, a plated part) Grinded into pockmarks), used to rub the obstacles. 16. For parts with more bending, adjust the bending step by step step by step. 17. When the molding viewpoint is adjusted, the R angle at the time of the small bending or the movement of the folding line reference can be obtained to complete the purpose of reaching the molding viewpoint. 18. When adjusting the mold, most of the gaskets are used to adjust the height of the molding. It is possible to move the male parts back and forth. The gaskets are generally made of stainless steel. (If the customer bans the gasket, wait for the mold to adjust and then make a new workpiece to the customer) 19, stainless steel data mold molding, can not use TD, to use (TICN) or PVD. 20. It is necessary to determine when the official information of the guest arrives, and save the use of data during the test, to prevent the phenomenon of insufficient data. 21. There are two types of sensors in the continuous mode, one is the step sensor and the other is the blanking sensor. 22. The slope of the waste funnel is not less than 30 degrees. The Scope box for the low viewpoint can be handled by installing a pneumatic vibrator (Pneumatic Vibration). 23. For trimming lines that are affected by molding, it is necessary to select and cut after forming, and the special orientation can be completed by cross cutting. 24. For multiple reference hole positions, it is best to use a single punching method to prevent the impact accuracy after step cutting. 25. Regarding the analysis of the test mode, it is necessary to analyze the strip after the test, and analyze the work piece one by one, and attach the red tape. 26. Regarding product cracking, it can adopt various methods such as adding package, extruding, adding sheeting forming area, opening and other methods in the early stretching, and performing CAE analysis before changing the mold. 27, product information is divided into coil material coil and sheet material two, some of the coil material to the factory after the demand is divided into strip width, generally in the striping scale is negative public service (negative 0.5mm), and the coil material The inner diameter should match the dimensions of the feed rack to prevent it from being too big or too small and too heavy. 28. When the mold is processed, the pin hole of the wire cutting is generally used as the reference of the number of hits. After the CNC is programmed, the operator is required to give the coordinates of the two holes to the programmer. After the programmer asks for the viewpoint, the program is placed. Processing after the viewpoint. Generally, when the template is first processed, the edge processing does not require the viewpoint. 29, the concept of fine punch is not to leave the gap (or only 0.5{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030}). Generally, the blanking gap is 10{79e4fc1217237f34a2b6b85aa45956718364b30a56d5d5602af9cce4e6b77030} of the thickness of the data. The thicker the data, the larger the void fraction. 30. If the metal model is not up to the standard, it can be finished by shaping, including plum pile, flattening again, simple punching and so on.
