Each roller power for each roller is average, total production line is stressed, the wear is balanced, and the service life of the roll is extended.
Roller material good material is to use its wear resistance, but the specific strength and hardness are contradictory, the red hardness should be utilized during heat treatment, and the hardness can be achieved after two or even three times of tempering after quenching.
The arc part of the track is the core part of the slide rail. The arc position of the first few passes after the press forming, in the subsequent pass rolling the vertical edge, the formed arc should be formed, and the effective tube bundle protection is carried out by the upper and lower rolls or the horizontal wheel.
Otherwise, the arc position of the material will change during the stretching process, R becomes smaller and becomes a triangle, the steel ball is not in the end, the two points contact the noise, and when the R becomes large, the coordination rail is swayed, and the track is blurred when used. Uneven force, deformation of the slide rail and shortened life.
Rolling stability problem, the production often encounters the problem of material yaw in the raceway, in fact, the single set of rollers is asymmetrical, the left side is strong, the material is yaw to the right; the right side is strong, the material Deflection to the left.
