Hello, masters, why does the single punch die bend twice at a time, and the height of both sides of the product is uneven, and the angle is greater than 90 degrees? How to solve it. be ...
Before bending, the material will be bent due to inaccurate movement and positioning, and the two sides will be uneven; Collectively referred to as grabbing materials;

The reason why it is greater than 90 should be caused by the rebound of materials; The above problems: First of all, the positioning of the material before bending should be accurate, the bending position should be made with rebound compensation angle and strong pressing rib, and the two bending punches should be as high as possible with negative clearance, so as to ensure the positioning, pressing, strong pressing and rebound compensation angle and solve the problem.
