1. The thicker the
stainless steel sheet, the greater the bending force required, and as the thickness of the plate increases, the margin of bending force should be larger when selecting bending equipment. Stainless steel has poorer thermal conductivity than ordinary low-carbon steel, and the extension The rate is low, resulting in a large deformation force required;
2. The greater the tensile strength, the smaller the elongation, the greater the required bending force, and the larger the bending angle should be. Compared with the stainless steel with the same thickness as carbon steel, the bending angle is larger. Special attention should be paid to this point, otherwise it will Bending cracks appear, affecting the strength of the workpiece;
3. In the case where the plate thickness corresponds to the bending radius in the design drawing, according to experience, the unfolded dimension of a bent workpiece is the sum of the right-angled sides minus the two plate thicknesses, which can fully meet the design accuracy requirements, and the unfolded amount can be calculated according to the empirical formula. Simplify the calculation process and greatly improve production efficiency;
4. The greater the yield strength of the material, the greater the elastic recovery. In order to obtain a 90-degree angle of the bent part, the smaller the angle of the press knife must be designed, the austenitic stainless steel is bent relative to the carbon Steel has a large elastic recovery deformation, so the angle of the pressing knife is smaller than that of carbon steel.
