1. The calculation of the neutral layer in the deformation zone is accurate, the calculation of the material used in the deformation zone is accurate, and the symmetry of the roller processing is good.
2. The non-deformed area should not be pressed as much as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers should be consistent during assembly.
3. Before the material is bitten, the guiding inclined opening should be set according to the rolling state of the front track. Before the material is stably pressed, the material slides smoothly in the rolling.
4. The accuracy of the roller processing is the key. For this reason, a special tool is specially made under the projector and magnified 20 times for testing.
5. On the main transmission side, the roller taper bearing is used to ensure that the radial runout of the main shaft is within 0.04MM and that the main shaft will not move left and right. Ordinary ball bearings have gaps themselves, and axial movement cannot be avoided during transmission.
6. The problem of bending and twisting in production is mainly caused by unbalanced force, left and right forces are unbalanced, left and right bending, and up and down forces are unbalanced, resulting in distortion. Solution: The design is balanced in force, accurate in processing, and convenient in installation and adjustment.
