1. The unit size, plate thickness, bending strength, the greater the thickness is, and the bending force should be greater when selecting bending equipment. Stainless steel, because its poor thermal conductivity is lower than ordinary low-carbon steel and low elongation, leads to deformation force;
2. The larger the unit size and tensile strength are, the smaller the elongation is, and the larger the bending strength and discount corner should be. The larger the folding bending angle is, compared with the stainless steel with the same thickness of carbon steel, the larger the folding bending angle should be. Special attention should be paid, otherwise bending cracks will occur that will affect the strength of the workpiece;
3. In the case of designing the corresponding plate thickness and bending radius, according to experience, the workpiece bending is the size of the right side minus two thicknesses, which can fully meet the design accuracy requirements. According to the empirical formula, the calculation amount can simplify the calculation process and greatly improve the production efficiency;
4. The greater the yield strength of the material, the greater the elastic recovery. In order to obtain a bending angle of 0 degrees, the smaller the pressure required is, the smaller the angle design. Austenitic stainless steel recovers elastically in bending relative to carbon steel, so the pressure angle is smaller than carbon steel.
