Product Specification

Four-Roller CNC Plate Rolling Machine With Pre-Bending Function 25mm Thick Plate High Performance And Heavy Duty

Brief introduction:

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 cylindrical and arc-shaped workpieces of various specifications at one time. With the help of auxiliary devices, it can roll conical cylindrical parts.

Advantages:

1. The material alignment, pre-bending and rounding of CNC four-roll plate rolling are completed in one rolling process. The remaining straight edge of pre-bending is ≤1.5 times the plate thickness, and the rounding accuracy is high. This four-roller plate rolling machine can perform symmetrical or asymmetrical bending according to the arrangement of the adjustment positions of the rollers on both sides. Therefore, the machine can roll into an ideal cylinder at one time without using a press to pre-bend the plate end.

2. The pre-bending rises through the lower roller to clamp the end of the steel plate, and the side rollers rise obliquely to achieve pre-bending of the end of the plate.

3. The lifting and lowering 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 synchronization accuracy of ±0.15mm.

4. The lower roller and side roller of this machine can be tilted at one end, and can rise and fall simultaneously in the tilted state.

5. The upper and lower rollers are both main drives, and the friction between the steel plate and the roller drives the side rollers to rotate, providing torque for the rolling.

6. Compared with the symmetrical three-roller plate bending machine, the four-roller plate bending machine can directly pre-bend the end of the plate without the help of other equipment molds, and the remaining straight edge is smaller; compared with the asymmetric three-roller plate bending machine, it can do without the plate. Turn around and roll into workpiece. This not only improves the efficiency and ensures the quality.

Way of installation:

1. install it on the ground

2. install it under the ground
