When a drawing die design performs drawing processing, that is, before drawing, during drawing and after drawing, what assistance processes are required? In addition, when stamping and drawing manufacturers carry out process design, they should try to be as compact as possible and reduce the frequency of deep drawing, thereby reducing auxiliary processes and costs.

The pre-drawing process, the general stamping and drawing manufacturer is to soften, clean and moisten the material; the process of deep-drawing includes softening, painting and Lubrication; assisting processes after deep drawing, generally including stress relief annealing, cleaning, deburring, surface treatment, testing, etc.

How long is the service life of stretched aluminum stamping? In addition to reasonable mold structure, extremely high manufacturing accuracy, better heat treatment effect, and correct selection of punching needles and installation accuracy of stamping, the standardized use, maintenance and maintenance of molds cannot be ignored.

1. Strictly check the stamping before installation and use, and remove the dirt, and carefully stamp the guide sleeve and mold for good lubrication.

2. Regularly check the punching turntable and die mounting base to ensure the coaxial accuracy of the left and right wheel discs.
