What is Plate Rolling Machine?

The plate rolling machine is a kind of equipment that uses work rolls to bend sheet metal. It can form parts of different shapes, cylindrical and tapered. It is essential processing equipment. The working principle of the plate bending machine is to move the work roll through the action of hydraulic pressure, mechanical force, and additional external parties to make the plate bend or bend into shape. According to the rotation, movement, and position changes of work rolls of different forms, the plate rolling machine can process parts such as the oval, arc, and cylindrical elements.

3-roll plate bending machine VS 4-roll plate bending machine

In the 3-roll plate bending machine , the upper roller of the 3-roll plate bending machine uses the hydraulic oil in the hydraulic cylinder to act on the piston to move vertically at the central symmetrical position of the two lower rollers. Provide torque for rolled sheets. The flat plastic metal plate of the bending machine passes between the three working rolls (two lower rolls and one upper roll) of the bending machine. With the help of the lower pressure of the upper roll and the rotation of the lower roll, the metal plate is passed through multiple passes. Continuous bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed) to produce permanent plastic deformation and roll into the required cylinder, cone, or part of them. The disadvantage of this hydraulic 3-roller bending machine is that the end of the plate needs to be pre-bent with the help of additional equipment. This rolling machine is suitable for large, more than 50mm thick devices. A row of fixed idlers is added under the two lower rollers to shorten the span of the two lower rollers, thereby improving the precision of the rolled workpiece and the machine’s overall performance.
