What should be paid attention to when selecting materials for hardware stamping parts?

Attention should be paid to the selection of materials for hardware stamping parts:
1. In the types of steel plate specifications, whether it is fixed length plate or rolled plate, materials of the same material and thickness have different coil widths and sales prices. So, in order to reduce costs, efforts need to be made in the formulation of procurement roll widths, and try to select roll width ranges that do not increase prices while ensuring material utilization. For fixed length plates, it is advisable to choose appropriate specifications and sizes. After cutting from the steel plant, there is no need for secondary cutting to reduce cutting costs; For sheet metal, it is advisable to choose the specifications and processes of the coil material for unwinding and forming, in order to reduce the workload of secondary shearing and improve work efficiency.
2. The thickness of the board has deviation requirements, usually within the allowable range of deviation. The board with the lower deviation should be selected first.
3. The determination of the shape and size of the unfolded sheet metal for stamping parts is a prerequisite for analyzing the degree of deformation of stamping parts, designing processability, and formulating process regulations. If the shape of the sheet metal is appropriate, not only can the uneven distribution of deformation along the sheet metal be significantly improved, but the forming limit can also be increased, and the protrusion height can be reduced, reducing the trimming margin. In addition, for some parts that are directly formed after being cut off, if precise sheet shape and size can be provided, the number of trial mold adjustments can be reduced, thereby shortening the production cycle and improving productivity.
4. When selecting materials for product design, avoid using high-grade materials that may result in excessive product performance. At the same time, while meeting product and process requirements, try to choose the materials and thicknesses used in existing mass-produced vehicle models to form a material platform, providing convenience for subsequent procurement and inventory management. The key performance requirement for ordinary cold-rolled sheets is their stretchability, so it is advisable to choose materials of lower grades while meeting product quality requirements. For the selection of material thickness, in addition to considering the strength and weight of the formed body, attention should also be paid to the popularization of material thickness. Due to the special material thickness, it is difficult for suppliers to supply, and the price is also high.
