How to choose the material of stamping parts
Stamping parts are a process that uses punches and dies to deform or break stainless steel, iron, aluminum, copper and other plates and other materials to achieve a certain shape and size. If the material of the stamping parts is not selected properly, defective products are prone to appear, leading to high costs, etc. Next, let us understand what issues should be paid attention to when selecting the material of the metal stamping parts? Matters needing attention in material selection of stamping parts: In steel plate specifications, whether it is a cut-to-length plate or a coil, the same material and material thickness have different roll widths and different sales prices. Therefore, in order to reduce the cost of metal stamping processing, it is necessary to start from the perspective of formulating the width of the purchase volume, and on the premise of ensuring the utilization of materials, without increasing the price, try to choose the volume width range. If the size of the fixed-size board is appropriately selected, after the stamping is completed, there is no need to perform secondary shearing to reduce cutting costs. For coils, please try to select the coil forming specifications and unwinding forming process, and reduce the number of times, reduce the workload, and improve work efficiency. Determining the shape and size of the unfolded sheet of stamping parts is the prerequisite for analyzing the degree of deformation of stamping parts, designing workability and formulating process specifications. If the shape of the sheet material is appropriate, not only the deformation distributed along the sheet material is not uniform, but also the forming limit can be increased, the height of the lugs can be reduced, and the trimming margin can be reduced. In addition, for some parts that are formed directly after punching, if accurate sheet shapes and dimensions can be given, the number of mold adjustments can be reduced, thereby shortening the production cycle and improving productivity.
