Cold forming machine

1. Through the principle of average force each time, the rollers of the entire production line are evenly stressed, the wear is balanced, and the service life of the rollers is prolonged.

2. The arc part of the track is the core part of the slide rail. The arc position after the first few passes is suppressed and formed. When the vertical edge is rolled and folded in the next pass, the arc formed should be effectively protected by the upper and lower rollers or horizontal wheels. Otherwise, the arc position of the material will definitely change during the stretching process. R becomes smaller and becomes a triangle, and the steel ball is not at the bottom. Two-point contact will produce noise. When R becomes larger, the matching track will shake and the track will become blurred when using the slide rail. Uneven force and deformation of the slide rail shorten the service life.

3. Rolling stability issues. The problem of deflection of the raceway material is often encountered in production. In fact, a single set of rollers is asymmetrical, with the force on the left side and the material deviating to the right; the pressure on the right side is great, and the material swinging to the left.

4. The problem of bending and distortion in production is mainly due to unbalanced force, unbalanced force on left and right, bending of force on left and right, and deformation of unbalanced force on upper and lower sides. Solution: Balanced design force, accurate processing, convenient installation and debugging.

5. The machining accuracy of the roller is the key. To this end, a special tool was specially made to detect the bottom of the projector and zoom in 20 times.

6. Tapered roller bearings are used on the main drive side to ensure that the radial runout of the main shaft is within and outside 0.04MM to ensure that the main shaft does not move left or right. Ordinary ball bearings have their own clearance, and axial movement cannot be avoided during accurate transmission.
