Try to use large gap punching as much as possible based on the specific situation, while ensuring that the workpiece does not experience edge collapse; The straightening process should be "straightened" rather than "smashed straight"; The drawing depth distribution of each sequence of the drawing piece is critical; Cold stamping parts should pay attention to the anisotropy of the material (which is related to the binding method of the raw material). This will not be displayed in the blanking and punching processes, but it will be very obvious in the deep drawing process, and sometimes in the bending process. Therefore, it is important to pay attention to the layout method before forming; For processes with subsequent surface treatment (especially coloring processes), it is necessary to control the uniformity of the chemical composition of the raw materials.
