Advantages of 4 roller plate bending machine


The CNC four-roller plate rolling machine can process and roll metal sheets into various parts such as cylinders, cones, and arc plates. The four-roller plate rolling machine can pre-bend and roll various specifications of cylindrical and arc-shaped workpieces at one time. With the aid of auxiliary devices, it can roll tapered parts.


The material alignment, pre-bending, and rounding of the CNC four-roller coiling are completed in one coiling process. The remaining straight edge amount of pre-bending is less than 1.5 times the thickness of the plate, and the rounding accuracy is high. According to the arrangement of the rollers on both sides of the four-roller bending machine, we can perform symmetrical or asymmetrical bending. Therefore, the machine can be rolled into an ideal cylinder at one time, without using a press to pre-bend the plate end.


The pre-bending is lifted by the lower roller, clamping the end of the steel plate, and the side roller is inclined to rise to realize the pre-bending of the end of the plate.


The lifting displacement of the lower roller and side roller of the machine is controlled by an intelligent PLC programmable controller, with automatic leveling, digital display on the screen, and a synchronization accuracy of ±0.15 mm.


The bottom roller and side roller of this machine can be tilted at one end and can rise and drop simultaneously in the tilted state.


The upper and lower rollers are the main drives, and the side rollers are driven to rotate by the friction between the steel plate and the rollers to provide torque for the winding.


Compared with the symmetrical three-roller bending machine, the four-roller bending machine can directly pre-bend the end of the plate without using other equipment molds, and the remaining straight edges are smaller. Compared with the asymmetrical three-roller bending machine, it can roll into a workpiece without turning the plate. This not only improves the efficiency, guarantees the quality of the workpiece, but also has a simple process and convenient operation, which reduces the labor intensity of workers.
