Application fields and manufacturing technical standards of metal stamping parts
Gold stampings are used in all areas of our lives:
1. In steel plate specifications, whether it is a cut-to-length plate or a coiled plate, the coil width of the same material and the same material thickness is different, and the sales price is also different. Therefore, in order to reduce costs, efforts should be made to determine the purchase roll width, and on the premise of determining the material utilization rate, try to choose a roll width range that does not increase the price. For example, for fixed-length plates, try to choose the appropriate size. After cutting from the steel mill, there is no need for secondary cutting to reduce cutting costs; for coiled plates, the specification and process of uncoiled coils should be selected as much as possible to reduce the workload of secondary shearing and improve work efficiency.
2. The thickness of the plate has deviation requirements. Generally, plates with smaller deviations should be selected within the allowable range of deviations. Metal stamping parts bending
3. The determination of the shape and size of the stamping part reaming sheet is the premise of analyzing the deformation degree of the stamping part, designing the processing performance, and drafting the process specification. If the shape of the sheet is suitable, it can not only significantly improve the uneven distribution of deformation along the sheet, but also increase the forming limit, reduce the height of the lug, and reduce the trimming allowance. In addition, for some parts that are directly formed after blanking, if the accurate shape and size of the sheet can be given, the number of mold trials and mold adjustments can be reduced, thereby shortening the production cycle and improving productivity.
