Plate rolling machine is a kind of common forging machine equipment that can bend and roll nonmetallic sheet metal into cone, spherical body, cylinder or other shapes. This performance is widely used in manufacturing, boiler steam, chemical industry, nonmetallic structure and machine building. Four-roller plate rolling machine is suitable for sheet metal bending forming work, can roll round, arc and conical workpiece within a certain range, and sheet metal end pre-bending function, the remaining straight edge is small, high efficiency, and can be used on the machine for rough leveling of sheet metal.

The four-roller bending machine is composed of four rollers. The upper roller is mainly driven and the position of the upper roller is fixed. The two ends of the lower roller are driven by the hydraulic cylinder. The lower roller can be raised to clamp the plate head with the upper roller, and bend the head at both ends of the plate according to the distance between the side roller and the upper roller. Then the lower roll drops, the two side rolls rise, and the plate bends into a cylinder. Any machine should be operated correctly in accordance with the requirements of the process. Let's talk about the correct operation method of the four-roller bending machine.

Preparations are generally made in the following aspects:

1. Define machine functions

Plate rolling machine is a kind of common forging machine equipment that can bend and roll non-metallic sheet metal into cone, spherical body, cylinder or other shapes. This performance is widely used in manufacturing, boiler steam, chemical industry, non-metallic structure and machine building.

Understand the working principle of the machine

Four-roll rolling machine and three-roll rolling machine roller motion form is different, but the working principle is the same, are using the principle of three-point circle to carry out different radius rolling. The position of the upper roller is fixed, and the lower roller moves upward in a straight line to clamp the steel plate. The curvature radius of the drum can be adjusted by moving the roller up in a straight line or arc.

Be familiar with operation procedure

(1) The plate rolling machine must be managed by special personnel.

(2) the operator must be familiar with the structure performance and use of the winding machine, after the responsible management personnel agree, can be operated.

(3) Carefully check whether the safety device is in good condition before starting.

(4) During operation, hands and feet are strictly prohibited to be placed on rollers and transmission parts and workpieces.

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

(6) There must be a special person to direct multi-person cooperative operations.

(7) Overload is strictly prohibited.

(8) The lifting and reversing of the upper roll, the dumping and reset of the bearing and the balance of the upper roll shall be carried out after the main drive stops.

(9) It is forbidden to pile up workpieces and sundries in the work site, and keep the machine tools and the site clean at all times.

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

Four-roller plate rolling machine is an important equipment in the production of enterprises, you must operate in the correct way during the use, otherwise not only equipment damage affect the production, but also will have unexpected consequences.
