Working principle of rolling machine


Jun 07,2023

Rolling machine is a type of equipment that uses work rollers to bend and shape sheet metal, capable of forming different shaped parts such as cylindrical and conical parts. It is a very important processing equipment. The working principle of a rolling machine is to use external forces such as hydraulic pressure and mechanical force to move the working rollers, thereby causing the sheet metal to be bent or rolled into shape. Based on the rotational motion and orientation changes of different shapes of work rolls, elliptical parts, curved parts, cylindrical parts, and other parts can be processed.

The upper roller of the symmetrical plate rolling machine passes through the hydraulic cylinder in a symmetrical direction at the center of the two lower rollers

Oil is used for the vertical lifting movement of the piston, which is driven by the final gear of the main reducer to drive the two lower roller gears to mesh and rotate together, providing torque for the rolled sheet metal. The standard flat plastic metal plate of the rolling machine passes between the three working rollers (two lower rollers and one upper roller) of the rolling machine. With the downward pressure of the upper roller and the rotational motion of the lower roller, the metal plate undergoes multiple consecutive twists and turns (inner layer compression deformation, middle layer unchanged, outer layer stretching deformation), undergoes plastic deformation, and is rolled into the required cylinder, cone, or part of them. The defect of this hydraulic three roller plate rolling machine is that the end of the plate needs to be pre bent with other equipment. This rolling machine is suitable for large rolling machines with a rolling thickness of over 50mm. A row of fixed rollers is added below the two lower rollers to shorten the span between the two lower rollers, thereby improving the accuracy of the rolling workpiece and the overall performance of the machine.
