What are the Factors that Affect the Size and Angle of Bending?

1. Different cores of the upper and lower dies for knives will lead to deviations in bending dimensions, and the knives should be in place to ensure that they are in place.
2. The relative distance to the lower die changes after the left and right position of the backstop is moved. Available cursor caliper measurement after fine adjustment through the rear stop screw.
3. Bending workpiece and the lower die parallelism is not enough, the upper die after the rebound of the workpiece under pressure, affecting the bending size.
4. A bending angle is not enough, the second bending size will be affected.
5. The cumulative error of bending will lead to an increase in the size error of the workpiece. Therefore, it is particularly important to ensure the accuracy of single-sided bending.
6. Material characteristics and thickness will affect the bending angle, so each workpiece bending must be the first inspection and strengthen the sampling inspection.
7. The length and thickness of the workpiece requires different pressure, the length and thickness of the plate is proportional to the pressure. So the workpiece length and thickness changes must be readjusted when the bending pressure.
8. The size of the lower die V mouth and bending pressure is inversely proportional to the plate length and thickness of a certain case, the larger the V groove the smaller the pressure required, so in the processing of different thickness of the workpiece to use the correct size of the lower die V groove as specified.
9. At one end of the bending machine, that is, a single side load processing, bending pressure will be affected, and is also a harm to the machine tool, is clearly prohibited. In the distribution of the mold should always keep the middle part of the machine tool under pressure.
10. The mold deformation, damage, wear and other phenomena will have an impact on all aspects of bending and forming, once found to be promptly reported to correct.
