Description

1. The principle of the average force of each pass, the rollers of the whole line are equally stressed, the wear is balanced, and the service life of the rollers is extended.
2. The use of C12MoV material for the roll is to take advantage of its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV should be used during heat treatment. After quenching, the hardness can be achieved by two or even three tempering.
3. The arc part of the track is the core part of the slide rail. The arc position after the first few passes is pressed and formed. When the vertical edge is rolled and folded in the later pass, the formed arc shall be effectively protected by the upper and lower rolls 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 to the bottom. Two-point contact will produce noise. When R becomes larger, the matching rail will shake, and the track will be blurred when the slide rail is used. Uneven force, deformation of the slide rail, shortening the life.
4. Rolling stability problem. The problem of material deflection in the raceway is often encountered during production. In fact, a single set of rollers is asymmetrical, the left side is stressed, and the material deviates to the right; the right side is heavily stressed, the material Swing to the left. The way to untie is:
a: (As shown in the figure) 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 roller processing has good symmetry.
b: The non-deformed area should not be stressed 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 assembly.
