Why are metal stamping parts torn and twisted

When processing metal stamping parts, stamping factories will find that metal stamping parts are torn and twisted. What is the reason for this problem? Is it due to an error in the process flow or the quality of the raw materials? In fact, there are many reasons for the tearing and distortion of processed stamping parts, mainly including the following categories: 1. The design of the flanging forming mold is defective: the mold is a two-cavity left/right part shared, because this process is in addition to turning In addition, it also has the shape formation, and the product is particularly complex, and the bending is narrow, and the molding stipulates that the concave die material core is consistent with the molding surface, etc., resulting in a large mold structure standard molding process and a small total stripping area. 2. The main parameters of the forming process are not implemented in time: in the whole process of making and forming, the process specifies the cavity, the stripper core and the two products must be attached together, and squeeze when the slide of the CNC lathe guide rail is lowered. The plate is plastically deformed to complete the forming. The processing technicians did not immediately adjust the working pressure of the CNC lathe in this section according to the specific regulations of the processing technology, or did not communicate with each other during the work handover of each turn. The information content of the reliability of the CNC lathe's work pressure , Resulting in unstable quality of stamping parts.
