The basic design specifications of metal stamping parts metal stamping parts ⑴ design must meet the product and technology performance, and ease of assembly and repair. ⑵ design stamping must help to improve the utilization of metallic material, what is metal stamping, reduce material varieties and specifications, minimize material consumption. In permitting the use of inexpensive materials, metal stamping where there is, as far as possible so that parts do not waste and less waste punching. ⑶ design stamping must shape is simple, reasonable structure, to help simplify the mold structure, simplify the number of steps, which uses the least, the most simple stamping process to complete the processing of the entire part, then other methods to reduce the processing, metal stamping Diaobingshan and facilitates the pressing operation, easy to organize mechanization and automation of production, in order to improve labor productivity. ⑷ design stampings, to ensure the normal use, try to make the dimensional accuracy and surface roughness grade lower level requirements, and to facilitate the exchange of products, reduce waste, ensure product quality and stability. Inhibition Stamping metal stamping parts produce distorted stacker 24. punch blade ends repair a slant or curved. This is an effective way to slow punching power. Mitigation punching power, you can reduce the die side of the tensile force, and thus inhibit stamping produce stacker, distorted results. 5. Daily mold production, should pay attention to maintenance punching convex, die cutting edge sharpness. When the punching edge wear, tensile stress suffered material will increase, thereby stamping produce stacker, twisted tend to increase. 6. blanking clearance unreasonable or uneven gaps also produce stampings stacker, twisted reasons, need to be overcome. Progressive Die by punching metal stampings peripheral way more than expected to form the shape of pieces. Produce stacker, distorted mainly due to the impact of stamping punching power. Punching, blanking clearance due to the presence of the material on one side of the die is stretched (Material warped upward), compressed by the punch side. When using the stripper plate when the stripper plate pressed material use, how to make metal stamping, die to prevent the material side of warped upward, this time, the stress state material change accordingly. With the stripper plate to increase its binder force, by material punch side of that is stretched (compressive force tends to decrease), while the die surface material is compressed (tensile strength tends to decrease). Flip stamping die, that is due to the material surface caused by tension. So when punching, pressed and compacted material is produced prevent pieces stacker, where the focus of twisted metal stamping cheap, Chen Feng Hardware (certified), Diaobingshan metal stamping by the Dongguan City, Chen Feng Hardware Products Co., Ltd. provided.
