Analysis of sheet metal deep drawing technology
1. Mechanical analysis of deep drawing The formability of deep drawing can be understood by analyzing the mechanics of cylindrical container forming (cylindrical stamping). The components of cylinder stamping are: round steel plate (blank), punch, die, and anti-wrinkle plate. Cylindrical forming is a processing method in which a material is changed from a blank to a cylindrical part. The deformation state of the blank during cylindrical forming is shown in Figure 2. During the cylindrical forming process, the outer peripheral material of the blank flange is compressed in the circumferential direction, and compression deformation occurs. Due to the deformation, the material undergoes work hardening, creating a circumferential compressive stress in…
