Precision stamping parts stamping performance of the stamping material used and the technological requirement

by:Fortuna     2021-02-01
Precision stamping is after stamping, extrusion, rolling, welding, cutting and a series of manufacture process, due to its production difficulty is bigger, so to meet the requirements of production, achieve good effect, molding, products for precision stamping parts stamping materials have higher requirements. First of all, the requirement of precision stamping parts stamping material must have a certain stamping performance, so that can be easy to get high quality and high accuracy of precision stamping parts, for production and processing; At the same time, it's a stamping process limit deformation degree and the total limit deformation degree should be enough big, easy to improve production efficiency. But premise condition is stamping material loss of precision stamping parts, precision stamping die and wear. Second, precision stamping parts stamping materials shall meet the corresponding technical requirements, such as its thickness tolerance should comply with the standards. Although different mold clearance is suitable for the different thickness of the material, but if the material thickness tolerance is too big, not only directly affect the quality of the precision stamping parts, also may cause the damage of the mould or press. And material itself also should have high surface quality and not scale, crack, rusty spot, defects such as scratch and layered, good quality material during processing is not easy to broken, also not easy to scratch the mold, precision stamping parts of the surface quality. At the same time, the requirements in the production of precision stamping materials have high percentage elongation and percentage reduction of area, the lower the yield narrowing and high tensile strength, high plasticity, large deformation degree, is conducive to stability and deformation uniformity of stamping process and improves the precision stamping forming dimensional accuracy. In addition, stamping materials must continue to processing of mechanical joint and has good adaptive performance, reduce the possibility of damages to the mechanical equipment. Use of material can meet these requirements and production of precision stamping parts, quality guaranteed.
