Distortion solving method of cold bending machine
Mar 15, 2018

1. Accurate calculation of neutral layer in deformation zone, accurate calculation of materials used in deformation area, good symmetry of wheel processing.

2, the deformation of the region as far as possible not under pressure (such as the bottom of the slide), assembly, upper and lower rollers in the gap between the same.

3, before the material bite, should be in accordance with the front of the rolling state, set the guide oblique mouth, in the stable compression before the material in the rolling slip smoothly.

4, the wheel processing accuracy is the key, for this purpose, specialized in the production of special tools under the projector, magnified 20 times times to detect.

5, the main transmission side, the use of roller cone bearings, to ensure that the spindle radial runout in the 0.04MM to inside and outside, to ensure that the spindle will not move around, ordinary ball bearings have their own gaps in the precise transmission can not avoid the axial movement.

6, the production of bending distortion of the problem, is mainly caused by unbalanced force, left and right by the force imbalance, left and right bending, up and down under the force imbalance, resulting in distortion. Solution: The design is balanced by force, the processing is accurate, the installation adjusts conveniently.


Previous: Cold bending machine will become the mainstream of development at home and abroad

Next: The development foreground of the domestic cold bending machinery at present
