Let's talk about the correct operation method of the four-roller CNC bending machine.


Generally prepare from the following aspects:

How to correctly operate the four-roller  CNC bending machine(图1)

1. Clarify machine functions


The plate rolling machine is a kind of public forging machinery and equipment that can bend non-metallic plates into cones, spheres, cylinders or other shapes. This performance is used in large widths in the creation, boiler steam, chemical industry, and non-metallic materials. Structure and machine building, etc.


2. Working principle


The four-roll bending machine and the three-roll bending machine have different roller motion forms, but the working principle is the same. They both use the principle of three-point fixed circle to roll with different radii. The position of the upper roller is fixed and the lower roller moves upward linearly to clamp the steel plate. The rollers on both sides move in a straight line or arc to move closer to the roller to adjust the radius of curvature of the roll.

3. Familiar with operating procedures


(1) The rolling machine must be managed by a dedicated person.


(2) The operator must be familiar with the structure, performance and use of the rolling machine, and can only operate after the approval of the responsible manager.

(3) Check carefully whether the safety device is in good condition before starting the machine.


(4) During operation, it is strictly forbidden to put hands and feet on the roller, transmission parts and workpieces.


(5) After work is interrupted, the clutch should be turned to neutral.


(6) Multi-person collaborative operations must be directed by a special person.


(7) Overwork is strictly prohibited.


(8) The tilting reset of the lifting and turning bearing of the upper roller and the balancing of the upper roller must be carried out after the main drive is stopped.


(9) It is forbidden to pile up workpieces and debris in the workplace, so that the machine tool and the site are kept clean at all times.


(10) After the operation is completed, the power supply should be cut off and the power box should be locked.


The four-roller plate bending machine is an important equipment in the production of enterprises. It must be operated in the correct manner during use, otherwise not only the damage to the equipment will affect the production, but also unexpected consequences will occur.
