How to arrange the production plan for U-shaped stamping parts

There are many different types of metal stamping parts, including precision stamping parts, metal stamping parts, automotive stamping parts and so on. U-shaped stamping parts are a kind of metal stamping parts, which are relatively widely used. For stamping factories, how to arrange the production plan for U-shaped stamping parts is a problem. Next, the author of Precision will introduce to you. When the part is a U-shaped stamping part, the production of the metal stamping part includes three basic processes: blanking, punching and bending. According to these processes, we can have three processing plans: Option one, blanking first, then punching In the bending, three sets of single-process molds are used for manufacturing; Option two, first blanking, punching, then conform to the stamping mold, and then bending, using composite molds and single-process bending molds for manufacturing; Option three, punching -Blanking, continuous stamping of the die, and then bending. Choose continuous mold and single-process bending mold for manufacturing; below, we will analyze these types of programs by scientific research: Program 1 The mold organization is simple, but it requires three processes and three molds, and the productivity is low. Scheme 2 Two sets of molds are required, and the shape and position accuracy and specification accuracy of the metal stamping parts produced by the composite mold are easy to ensure, and the productivity is high. However, because the hole row height of this part is 4.75mm, which is lower than the lower limit of the allowable wall thickness of the concave and convex mold is 6.7mm, it is not suitable for the selection of the compound stamping die process. Scheme 3 also requires two molds, and the productivity is also high, but the precision of the stamping mold of the part is slightly weaker. In order to ensure the shape and position accuracy of the metal stamping parts, it is necessary to set the guide pin on the mold, so the mold processing and installation are slightly more complicated than the composite mold; [Recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
