Working principle:
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, and the hydraulic oil in the hydraulic cylinder acts 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 rotational motion, so as to roll the plate. 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. This 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.

Due to the different fields of use, the types of plate rolling machines are also different. According to the number of rolls, it is divided into three-roller and four-roller. The three-roller is divided into a symmetrical three-roller plate rolling machine, a horizontal down three-roll plate rolling machine, an arc down type plate rolling machine, an upper roll universal three-roll plate rolling machine, and a hydraulic CNC plate rolling machine. From the transmission, it is divided into mechanical type and hydraulic type. In terms of the development of the plate rolling machine, the upper roll universal type is the most backward, the horizontal downward type is slightly advanced, and the arc downward type is the most advanced.
