Reasonable selection of stamping materials-hardware

Reasonable selection of stamping materials (hardware) The selection of stamping materials should consider the use requirements of stamping parts, stamping process requirements and economy. Reasonable selection of materials according to the requirements of the stamping process (1) Reasonable selection of materials according to the use requirements of the stamping parts  The selected materials should enable the stamping parts to work normally in the machine or components and have a certain service life. Therefore, according to the use conditions of the stamping parts, the selected material should meet the corresponding strength, stiffness, toughness, corrosion resistance and heat resistance. For any kind of stamping parts, the selected material should be able to follow its stamping process. It is a basic and important material selection requirement to form a qualified product that will not crack or wrinkle stably. For this reason, the following methods can be used to select materials reasonably. ① Test punch. Based on previous production experience and possible conditions, select several sheets that can basically meet the requirements of stamping parts for trial punching, and choose the one that has no cracks or wrinkles and has a low rejection rate. The result of this method is relatively intuitive, but with greater blindness. ②Analysis and comparison. On the basis of analyzing the properties of stamping deformation, compare the large deformation degree during stamping forming with the allowable limit deformation degree of sheet metal stamping forming performance, and use this as a basis to select the plate suitable for the stamping process requirements of this kind of part . .
