Distortion solution of cold bending machine


Distortion solution of cold bending machine:
   1. The neutral layer in the deformation zone is calculated accurately, the material used in the deformation zone is calculated accurately, and the roller processing has good symmetry.
   2. The non-deformed area should not be compressed as much as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers should be kept consistent during installation.
  3. Before the material is bitten into, a guide oblique opening should be set according to the rolling state of the front track, and the material will slide smoothly in the roll before being stably pressed.
  4. The accuracy of the roller processing is very important. For this reason, special tools are specially manufactured for inspection under the projector with a magnification of 20 times.
  5. The main drive side uses roller cone bearings to ensure that the radial runout of the spindle is within and outside 0.04MM to ensure that the spindle will not move left and right. There is a gap in the ordinary ball bearing itself, which cannot prevent axial movement during precise transmission.
  6. The problems of twists and distortions in production are mainly caused by unbalanced forces, unbalanced left and right forces, zigzags, unbalanced up and down forces, resulting in distortion. Solution: The design is balanced in force, the processing is accurate, and the installation and adjustment are convenient.
