How many deep drawing methods are there for metal stamping parts?
When stamping parts processing manufacturers use stamping equipment to deepen metal stamping parts, they usually use the following methods: 1. Panel drawing method Panel products are all flat metal stamping parts with complex surface shapes and roughness during the drawing process. Deformation is complex, and its forming performance is not only deep drawing, but also deep drawing and expansion conform to the forming; 2. The blank deformation on the flange of the elliptical drawing method is deep drawing, but the amount of deformation and the rate of deformation are along the contour shape Corresponding changes, the larger the curvature, the greater the plastic deformation of the metal stamping blanks. On the contrary, the smaller the curvature, the smaller the plastic deformation of the blanks. Third, the step drawing method; the original drawing product on the left is re-drawn to form The bottom of the step on the right, the deeper part is deformed at the beginning of the drawing, and the shallower part is deformed in the later part of the drawing, and the side wall of the stepped part is likely to cause shear stress deformation; 4. The deformation of the blank on the elliptical drawing method flange Drawing deformation, but the deformation and deformation rate change with the change of the contour shape. The larger the curvature, the greater the plastic deformation of the blank. On the other hand, the smaller the curvature, the smaller the plastic deformation of the metal stamping blank; Cylinder drawing method The drawing of cylindrical metal stamping parts with flanges. The flange and the bottom are in a plane shape, the side wall of the cylinder is axisymmetric, and the deformation is evenly distributed on the same circumference, and the blank on the flange produces deep drawing deformation; recommended article: What technical requirements should the stamping material meet? : How to inspect the metal stamping parts when the manufacturer receives materials?
