What should I pay attention to when flanging during stamping?

Representative bending flanging processes widely used in automobile parts include V-shaped bending, U-shaped bending, and L-shaped bending. With the development of society, the market has higher and higher requirements for precision stamping parts. In order to obtain better products, every process of production must be strictly checked. The content of this article will describe what should be paid attention to during the stamping process? First of all, the flanging process has the following characteristics: 1, cracks; 2, wrinkles; 3, wrinkles; 4, adhesion; 5, springback; 6, warpage, etc. Wrinkles will occur during flanging of elongated curved surfaces. A strong pressing device is used in the mold design to prevent it. In addition, to create favorable flanging conditions, to prevent premature flanging of the middle part and cause excessive elongation of the vertical edges. Deformation or even cracking, and the selection of the stamping direction should ensure that the flanging force is balanced in the horizontal direction. Usually the stamping and the tangent at both ends of the blank form the same angle. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
