a: The neutral layer of the deformation zone is calculated accurately, the material used in the deformation zone is calculated accurately, and the symmetry of the roller processing is good.
b: The non-deformed area is as free as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers is consistent during assembly.
c: Before the material is bitten, the guiding oblique opening should be set according to the rolling state of the front road. Before the pressure is stabilized, the material slides smoothly in the roller.
The problem of bending and twisting in production is mainly caused by the imbalance of the force, the left and right forces are unbalanced, the left and right are bent, and the upper and lower forces are unbalanced, resulting in distortion. Solution: The design is balanced by force, accurate in processing and easy to install and adjust.
The accuracy of the roller processing is the key. For this purpose, special tools are specially produced under the projector, and the magnification is 20 times for detection.
The main drive side adopts the roller cone bearing to ensure that the radial runout of the main shaft is within 0.04MM, ensuring that the main shaft will not move left and right. The ordinary ball bearing itself has a gap, and the axial movement cannot be avoided in the precise transmission.
