General stamping die by: up and down pallet, up and down pad feet, up and down mold base: the general use of A3, Q235 and other "soft material" made from supporting the entire mold to facilitate die-cutting, blanking and so on.

Upper and lower template: the upper and lower template from the fixed edge, into the block, into the child, the top material pin role, external positioning, internal positioning, floating guide pin, dual-use pin, guide plate, these are also fixed in the next The template, the next template hardness requirements must be around HRC58 ~ 62, the hardness is too low will affect the quality of punching. Thickness is generally 25 ~ 40mm. Some blade cut directly on the template, that is, in the template directly dig the blade, so if the blade is missing, collapsed, worn, burrs are not good repair mode; there is another approach is to dig into the block, That the knife edge dug into a block (the block used to be known as the "lower die blade"), and then into the lower mold under the template inside. Height to ensure the same as the next template, the error should be in the plus or minus 1 to 2, the best within plus or minus 0.005mm, the general grinder master or fitter can be achieved. Too many products will be printed (mold).

Upper and lower pads, pads generally made of Cr12. According to the needs of each mold up and down the thickness of the plate are not the same, look at punching force, if the red hole less, then the upper and lower plate can be properly made a little thin 8 ~ 10mm can, if punching more, it is necessary Appropriate to do a little thick, generally about 17 ~ 20mm. Underlying plate is mainly blanking holes, spring through holes, screw through holes, guide holes and other ventilation holes.

Upper and lower plywood, plywood up and down the main punch from the punch, punch, guide posts with the general can be 17 ~ 20mm. Stamping die plywood material hardness generally do not need particularly high, usually with soft material can be, but too soft not, it is possible to pull the punch hanging directly into the plywood inside to pull the plywood bad. Therefore, the design of stamping die, from the president of the workpiece blanking process to consider the structure of the mold, die material selection, the selected punch tonnage, blanking gap size, etc., in order to make the finished workpiece burr smaller , To extend the life of the mold.

Stop plate, stripper plate, stopper plate with Cr12, but the stripper must use hard materials such as Cr12Mov. Stopper and stripper plate by M6 or M8 screws and then locked together, the stop plate above is mainly some through holes, punch through holes, guide post holes and so on. Stripper mainly from the material, the pressure material, the role of leading punch. In general we use the stripper to guide the punch, guide post, punch. When aluminum is produced, it is necessary to use a stop plate to guide the punch because the aluminum flakes easily jump into the stripper, pull the punch to the hair, or jam the punch, pull the punch off and pull out the stripper. , While unloading plate unilateral appropriate enlarge 10 to 20; or stripper to do two, the above section is used to guide the following section also unilateral enlarge 10 to 20. Stop plate thickness of 8 to 17 mm, but also according to the number of punching, the size of the force to be seen; strip thickness of 20-25 mm.

Die, punch, also known as punch or knife, is used to wash away the excess material, cut off, or cut open, puncture, stretch. Such as: stretch punch, bending punch, slide the knife, hit the salad punch, punch convex punch, pumping Bud Chong, riveting punch riveting and so on. The material of the concave punch mold needs higher hardness. Common concave mold punch materials are: Cr12Mo1v1, Cr12Mov, Skd-51, Skd-11, W6Mo5Cr4V2 (tungsten steel) and the like.
