The working principle of the rolling machine

The upper roller of the symmetrical plate rolling machine is in the symmetrical position of the center of the two lower rollers through the hydraulic oil in the hydraulic cylinder acting on the piston to make vertical lifting motion, and the last stage gear of the main reducer drives the gears of the two lower rollers to mesh for a rotating motion, which is used for rolling plates. provide torque. The flat plastic metal plate of the plate rolling machine passes between the three work rolls (two lower rolls and one upper roll) of the plate rolling machine. With the help of the lower pressure of the upper roll and the rotation of the lower roll, the metal plate passes through multiple passes. Continuous bending (inner layer compression deformation, middle layer unchanged, outer layer tensile deformation), resulting in permanent plastic deformation, rolled into the required cylinder, cone or part of them. The disadvantage of this hydraulic three-roll plate bending machine is that the end of the plate needs to be pre-bent with other equipment. The plate rolling machine is suitable for large plate rolling machines with a thickness of more than 50mm. A row of fixed idlers is added to the lower part of the two lower rollers to shorten the span of the two lower rollers, thereby improving the accuracy of the rolled workpiece and the overall performance of the machine.

Regardless of whether it is a large or small enterprise using a plate bending machine or a factory similar to a plate bending machine manufacturer, this equipment must be equipped with a sealing device to prevent leakage during processing and the intrusion of dust.
In addition to gap seals, seals are used to control the gap between two adjacent coupling surfaces below the minimum gap through which the liquid to be sealed can pass. The seals in the hydraulic system of the plate bending machine are in contact seals, usually There are two types of self-sealing compression seals and self-sealing self-tightening seals, also known as lip seals. However, the factors affecting the performance of various seals in the hydraulic system of the plate rolling machine are different, just like the three-roller roll The seal of the trigger is actually still affected by the temperature, pressure and the existing medium.
