How to select materials reasonably for metal stamping parts

The nature of stamping materials is closely related to stamping production. Stamping factories need to pay enough attention to the selection of materials to ensure product quality and meet customer needs. So how does the stamping parts processing plant choose more reasonable materials? Generally, the use requirements, stamping process requirements and economy of metal stamping parts will be considered. The following author will introduce you. 1. Reasonable selection of materials according to the use requirements of metal stamping parts. The selected materials should enable the stamping parts to work normally in the machine or parts and have a certain service life. For this reason, the selected material should meet the corresponding strength, stiffness, toughness, corrosion resistance and heat resistance requirements according to the use conditions of the stamping parts. 2. Reasonable selection of materials according to the requirements of the stamping process. For any kind of metal stamping parts, the selected material should be able to stably form qualified products that will not crack or wrinkle according to the requirements of the stamping process. This is relatively basic and very important. The material selection requirements. 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 then select 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. (2) Analysis and comparison. On the basis of analyzing the properties of stamping deformation, compare the maximum 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 requirements of the stamping process . In addition, there are cold-rolled and hot-rolled plates of the same grade or thickness. Compared with the hot-rolled sheet, the cold-rolled sheet has accurate dimensions, small deviation, fewer surface defects, bright, dense internal structure, and better stamping performance. 3. Reasonable selection of materials according to economic requirements. The selected materials should be as low as possible, convenient in source, and economical on the premise of meeting the requirements of use performance and stamping process, so as to reduce the cost of stamping parts.
