40 * 2800 mechanical bending machine, Shanghai delivery

Plate bending machine is a molding machine for continuous point bending of plates. It has the function of rolling plates with different shapes such as O-type, U-type and multi-stage R. Working principle: the upper roll of the symmetrical plate rolling machine is at the symmetrical position in the center of the two lower rolls, the hydraulic oil in the hydraulic cylinder acts on the piston for vertical lifting movement, and the gears of the two lower rolls are meshed and rotated through the final gear of the main reducer to provide torque for plate rolling. The plastic metal plate with flat specification of the coiler passes between the three working rollers (two lower rollers and one upper roller) of the coiler. With the help of the lower pressure of the upper roller and the rotating movement of the lower roller, the metal plate is continuously bent for multiple passes (the inner layer is compressed and deformed, the middle layer remains unchanged, and the outer layer is stretched and deformed), resulting in plastic deformation, and rolled into the required cylinder, cone or part of them. The disadvantage of the hydraulic three roll bending machine is that the plate end needs to be pre bent with the help of other equipment. The rolling machine is suitable for large-scale rolling machines with a thickness of more than 50mm. A row of fixed idlers are added at the lower part of the two lower rollers to shorten the span of the two lower rollers, so as to improve the accuracy of rolling workpieces and the overall performance of the machine.
