How does a plate rolling machine work?

The plate rolling machine is a kind of equipment that uses work rolls to bend and form sheet materials. It can form parts of different shapes such as cylindrical parts and conical parts. It is very important processing equipment. The working principle of the plate bending machine is to make the work roll move through the action of hydraulic pressure, mechanical force and other external forces, so that the plate can be bent or rolled into shape. According to the rotational movement and position changes of work rolls of different shapes, elliptical parts, arc parts, cylindrical parts and other parts can be processed.

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 of the plate rolling machine. With the help of the lower pressure of the upper roll and the rotational movement of the lower roll, the metal plate is continuously bent for multiple passes, resulting in permanent plastic deformation. Roll into the desired 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.
