Requirements for materials and shapes of deep-drawn metal stamping parts

What are the requirements of stamping parts processing plants in terms of material, shape, and size for deep-drawn metal stamping parts? Let’s take a look below; 1. The materials used for deep drawing metal stamping parts should have good plasticity to ensure smooth deformation under the action of tensile force, low yield strength and high tensile strength, that is, low yield. Strength ratio, large plate thickness directivity coefficient and small plate plane directivity to reduce ear protection and trim margin; 2. The height of deep drawing metal stamping parts is as small as possible to reduce the number of drawing times and the drawing process The influence of the work hardening effect; 3. The shape of the deep drawing stamping parts is as simple and symmetrical as possible, so that the drawing deformation is even, so as to facilitate the forming; 4. The round corner radius r between the bottom and the side wall of the deep drawing metal stamping part, It should be r≥t (t is the material thickness, mm). In order to make the deep drawing smoothly, r≥(3~5)t should be taken, and rp ≥t, rp ≥2t should be met, and rpu003d(3~ 5) t,rdu003d(5~10)t; 5. The fillet radius R between the flange and the side wall of the deep drawing metal stamping part should be R≥2t. In order to make the deep drawing go smoothly, generally R≥( 4~8) t; 6. The fillet radius R1 between the four walls of the rectangular part should be R1 ≥ 3t. In order to reduce the number of drawing times, as much as possible R1 ≥ 0.2H (H is the height of the drawing part) so that it can be used once The drawing is successful, the fillet radius r1 between the bottom and the side wall of the rectangular deep-drawn stamping part should meet r1≥t; Recommended article: Stamping parts processing factory talk about the number and order of stamping parts processing Previous: Hydroforming technology for stamping parts The role of
