Metal stamping parts material selection
1. As far as possible, choose the right size for the length plate, after cutting from the steel plant, it is not necessary to perform secondary shearing to reduce the cutting cost; for the coil plate, try to select the shape and process of uncoiling and coiling, and reduce the number of The workload of the shear, improve work efficiency.
2. There is a deviation in the thickness of the plate, usually within the allowable range of deviations, the plate with the lower deviation should be selected first.
3. Determine the shape and size of the sheet metal of the metal stampings. It is a prerequisite for analyzing the degree of deformation of the stamped parts, designing the craftwork, and formulating the technological procedures. If the shape of the sheet material is appropriate, not only the phenomenon that the deformation is unevenly distributed along the sheet material can be significantly improved, but also the forming limit can be improved, and the height of the lug can be reduced and the trimming margin can be reduced. In addition, for some parts that are formed directly after blanking, if accurate sheet shapes and sizes are given, the number of trial die adjustments can be reduced, thereby shortening the production cycle and increasing productivity.
4, in the product design selection, to avoid the use of high-grade material caused by excess product performance, at the same time, to meet the requirements of the product, process, as far as possible to choose the existing production models used materials, material thickness, the formation of material platform, For the convenience of subsequent procurement and inventory management.
