The selection of metal stamping parts should follow these principles
1. For the fixed-length board, try to choose the appropriate size. After cutting from the steel mill, it is not necessary to carry out secondary shearing and reduce the cutting cost. For the coiling board, try to select the coiling material specification and process of the unwinding forming, reduce the second The workload of secondary shearing improves work efficiency.
2. Determining the shape and size of the Sheet metal unrolled by the metal stamping parts is the premise for analyzing the degree of deformation of the stamping parts, designing the craftsmanship and formulating the technical specifications. If the shape of the sheet is suitable, not only the uneven distribution of the deformation 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 directly formed after blanking, if accurate sheet shape and size can be given, the number of times of mold adjustment can be reduced, thereby shortening the production cycle and increasing productivity.
3, the thickness of the sheet has deviation requirements, usually within the allowable range of deviation, should first select the lower deviation of the sheet.
4. When selecting product materials, avoid using high-grade materials to cause over-performance of the products. At the same time, under the premise of meeting the requirements of products and processes, try to select the materials and materials used in the existing mass-produced models to form a material platform. Facilitate subsequent procurement and inventory management.
