Working Principle and Operating Procedures of Four Roll Plate Rolling Machine

The four roller plate rolling machine is composed of four rollers, with the upper roller being the main transmission and the position of the upper roller being fixed. The two ends of the lower roller are driven up and down by hydraulic cylinders. The lower roller can be raised to clamp the sheet head with the upper roller, and the distance between the side roller and the upper roller can be changed as needed to bend the sheet head at both ends. Then the lower roller descends, the two side rollers rise, and the sheet metal is bent and rolled into a cylindrical shape.

Any machine must be operated correctly according to the process requirements. Next, let's talk about the correct operation methods of the four roll rolling machine.

Generally, preparations are made from the following aspects:

1. Clarify machine functions

The rolling machine is a public forging machine equipment that can bend non-metallic plates into cones, spheres, cylinders, or other shapes. This performance is widely used in industries such as manufacturing, boiler steam, chemical engineering, non-metallic structures, and machine building.

2. Understand the working principle of the machine

The roller motion forms of the four roller plate rolling machine and the three roller plate rolling machine are different, but the working principle is the same. Both use the principle of three-point circle determination to roll with different radii. The position of the upper roller is fixed, while the lower roller moves upwards in a straight line to clamp the steel plate. Adjust the curvature radius of the drum by moving the rollers on both sides in a straight or curved line towards the upward roller.

3. Familiar with operating procedures

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

(2) Operators must be familiar with the structural performance and usage of the rolling machine, and can only operate with the consent of the responsible management personnel.

(3) Before starting the machine, carefully check whether the safety devices are in good condition.

(4) During operation, it is strictly prohibited to place hands and feet on the rollers, transmission components, and workpieces.

(5) After work interruption, the clutch should be set to neutral.

(6) Multi person collaborative work must be commanded by a dedicated person.

(7) Overloading work is strictly prohibited.

(8) The tilting and resetting of the lifting and flipping bearings of the upper roller and the balancing of the upper roller must be carried out after the main drive is stopped.

(9) It is prohibited to pile up workpieces and debris in the workplace, and the machine tool and site should be kept clean at all times.

(10) After completing the homework, cut off the power supply and lock the power box

The four roller CNC rolling machine is an important equipment in enterprise production. You must operate it in the correct way during use, otherwise not only will the equipment be damaged and affect production, but also unexpected consequences will occur
