Different bending stamping parts, different bending processes
Bending stamping parts are stamping products that bend metal sheets into a certain shape, size and bending rate. They are widely used in various utensils, instrument components, high-pressure vessels, etc. Different bending stampings, different bending procedures, and reasonable bending procedures can reduce the number of bending, simplify the mold structure, and improve the quality and productivity of stamping products. 1. For simple bending stamping parts, such as V-shaped, U-shaped, L-shaped, Z-shaped, etc., one-time bending can be used. For curved parts with complex shapes, it is generally necessary to use multiple bending forming. 2. For multi-angle bending stamping parts, the deformation will affect the shape accuracy of the bending parts. Therefore, it is generally necessary to bend the outer corners first, and then the inner corners. The previous bend should leave a reliable location for the next bend, and ensure that the next bend does not damage the shape of the previous bend. 3. Bent parts with asymmetric structure, the blanks are prone to deviation when bending, and the process of cutting in pairs after bending should be used as much as possible. Although the bending deformation is only a partial area of u200bu200bthe material, the rebound effect will affect the accuracy of the bending part. There are many influencing factors of springback and it is difficult to control. The accuracy of bending parts caused by springback has always been the key to bending production. The bending times and process arrangements of the bending parts need to be comprehensively considered according to the complexity of the shape of the stamping parts, the level of precision requirements, the properties of the materials, and the size of the production batch.
