Factors affecting the minimum bending radius of stamping parts

What are the factors that affect the minimum bending radius of stamping parts? Let’s take a closer look; 1. The mechanical properties of the material, the better the plasticity of the stamping material, the higher the plastic index, and the smaller the minimum bending radius; 2. The relationship between the fiber direction of the stamping material and the direction of the bending line. The sheet material is anisotropic, and the plastic index along the fiber direction is higher than the plastic index in the vertical fiber direction; therefore, if the bending bending line is perpendicular to the sheet fiber direction, the value of rmin/t is less than the bending line The fiber direction is parallel to the bending rmin/t value; when bending a workpiece with a small r/t, try to make the bending line perpendicular to the fiber direction of the sheet to increase the degree of deformation and avoid the outer fiber from cracking; multi-directional bending of the workpiece , Can make the bending line and the fiber direction of the sheet material be at a certain angle; Recommended article: What is the method of bending metal stamping parts?
