Angle error and size of CNC bending machine

Quality has always been the face of the product. How to improve the quality depends on the master’s operating skills and the quality of the production equipment. How to solve the large bending angle error of the CNC bending machine?

How to control the bending angle error of the CNC bending machine? How to grasp the size of the bending machine in bending?

1. Check whether the compensation cylinder compensation deflection of the CNC bending machine is large and the zero position cannot be completely restored

2, check whether the quick clamp of the CNC bending machine is loose

3. Check whether the bottom dead center of the CNC bending machine changes every time you bend

4. Check whether the bow plate installation of the CNC bending machine is standard, and whether the screw hole is dead.

5. Changes in the plate itself of the CNC bending machine (thickness, material, stress)

6. Is the grating ruler of the CNC bending machine loose?

7. The positioning accuracy of the CNC bending machine is inaccurate: Anhui Yongya feels whether the zero offset value of the proportional valve is appropriate, and the positioning cannot reach the bottom dead center, making it impossible to return

Bending machine size control method during bending:

1, to avoid cumulative errors, measure the unfolded size for each fold;

2, avoid using the bending machine to bend the side, and avoid using a large angle;

3. For products that must be bent by the bending machine, the previous bending angle should be slightly less than 90 degrees;

4. Determine the accuracy of the measuring tool before processing;

5, do the first inspection before the formal processing, and do the round inspection during the processing;

6. ​​The bending machine selects the appropriate machine according to the accuracy requirements of the processed product;

7. Avoid choosing different tools, make sure that the tip of the upper die is on the same straight line before processing;

8. Choose a good processing method and a good process layout method to simplify the processing difficulty;

9. The position of the bending machine is accurate, and any abnormal position needs to be detected immediately.
