working principle of 3-roll bending machine

3 roll bending machine
3 roll bending machine

The upper roller of the 3 roller plate bending machine acts on the piston in the symmetrical position of the two lower rollers by the hydraulic oil in the hydraulic cylinder to perform vertical lifting movement. The gears of the lower gears driven by the final gear of the main reducer engage the cooperative rotary motion of the two lower roller gears to provide torque for rolling the plate.

The flat metal plate of the 3 roll bending machine passes through the three work rolls (two lower rolls and one upper roll) of the coiling machine, and the metal plate passes through multiple passes using the lower roll of the upper roll and the rotation of the lower roll. Continuous bending, produces permanent plastic deformation, rolling into the desired cylinder, cone, or part thereof.
