How to deal with the problem of large angle error in CNC press brake

Judging the quality of an automatic bending machine mainly depends on the wire feeding accuracy, bending angle and rotating angle of rotating arm. Recently, we have received the same problem from customers, that is, how to deal with the large bending angle error, which can be checked and solved from the following aspects.
When the automatic bending machine is running, the bending angle error is large, which should be dealt with from the following aspects:

1. Check whether the compensation deflection of the compensation cylinder of the automatic bending machine is large, and it can not completely return to the zero position;
2. Check whether the quick clamping wedge of the machine is loose;
3. Check whether the dead point of the equipment changes under each bending;
4. Check whether the automatic bending machine bow plate installation is standard and whether the screw hole is jacked up;
5. It is difficult to change the material, size and shape of the bending products;
6. Whether the grating ruler of automatic bending machine is loose;
7. The positioning accuracy of automatic bending machine is not accurate, whether the zero offset value of proportional valve is appropriate, and the positioning can not reach the bottom dead center, which makes it impossible to return.
