Causes and countermeasures for bending deviation of metal tensile parts

In the production process of metal stretched parts, it is inevitable to produce some product defects, such as bending deviation. Therefore, we need to analyze the causes of this bending offset problem, and give reasonable countermeasures in combination with the actual production. Especially now with the development of science and technology, people's demands and requirements for metal tensile parts are getting higher and higher. Let's briefly introduce it. 1. Reasons When the blank slides along the surface of the die during the bending process, it will receive frictional resistance. If the frictional resistance on both sides of the blank is different, the blank will shift to the side with the larger frictional resistance. 2. Countermeasures for curved parts with asymmetrical shapes, adopt symmetrical bending (single-sided curved parts are cut symmetrically after two pieces are bent); an elastic pressing device is added to the bending mold, so that the blank can be pressed to prevent movement during bending ; Adopt the inner hole and shape positioning form to make the positioning accurate.
