Introduction

Bending machine is a kind of equipment that uses work rolls to bend the sheet metal. It can form parts of different shapes such as cylindrical parts and cones. It is a very important 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 other external forces, so that the plate is bent or rolled into shape. According to the rotation movement and position changes of work rolls of different shapes, parts such as oval, arc, and cylindrical parts can be processed.

 

Working principle

The upper roller of the symmetrical plate rolling machine is at the symmetrical position of the two lower rollers through the hydraulic oil in the hydraulic cylinder to act on the piston for vertical lifting movement, and the final gear of the main reducer drives the gears of the two lower rollers to mesh for rotating motion, which is the rolling motion. Provide torque. 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 passes 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 three-roller bending machine is that the end of the plate needs to be pre-bent with the help of other equipment. This rolling machine is suitable for large rolling machines with a thickness of more than 50mm. 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 overall performance of the machine.
