How to solve the offset of bending stamping parts during the bending process
When stamping parts are produced by stamping processing factories, various problems will occur, resulting in waste of costs, reduction of production efficiency, and so on. Therefore, we must understand the causes of these problems, analyze and verify, so as to avoid the problems. The author of this article will introduce you to the reasons and solutions for the offset of bending stamping parts during the bending process. 1. Reason: When the blank slides along the surface of the die during the bending process, it will be subjected to frictional resistance. If the frictional resistance on both sides of the blank differs greatly, the blank will shift to the side with larger frictional resistance. 2. Solution: (1) The curved parts with asymmetrical shape are formed by symmetrical bending (single-sided curved parts are symmetrically bent with two pieces and then cut). (2) An elastic material pressing device is added to the bending die, so that the blank can be pressed to prevent movement during bending; (3) The inner hole and shape positioning form are used to make the positioning accurate.
