About the three-roller rolling machine maintenance rules

[Jun 22,2019]

The upper roller of the three-roller reeling machine acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder in the central symmetrical position of the two lower rollers, and the two lower roller gears are meshed by the final gear of the main reducer for the rotary motion, which is a rolled plate. Torque is provided. The flat plastic sheet of the coiling machine passes through the three work rolls (two lower rolls and one upper roll) of the winding machine, and the metal plate passes through multiple passes by the lower pressing of the upper roll and the rotating motion of the lower roll. Continuous bending produces permanent plastic deformation and is rolled into the desired cylinder, cone or part of it.
The maintenance rules for the three-roller coiling machine are explained as follows:
1. According to the requirements of the machine lubrication diagram, refuel the oil cup lubrication and manual lubrication points as required.
2. The coil is made according to the parameters specified by the coiling machine. The thickness of the coil is 20mm, the maximum length is 2500mm, and the yield limit of the coil material is less than 250Mpa.
3. After the power is turned on, carry out the lifting movement of the lower roller in the forward and reverse directions and the upper roller to check whether the movement is abnormal or not.
4. Operate strictly according to the processing procedure and operation method of the coiling plate. When the upper roller is lifted to the limit position, it is necessary to pay great attention to the safe operation of the equipment.
5. When the main drive is stopped, the upper roller can be lifted and lowered, the tilting of the inverted bearing and the lifting of the upper roller.
6. In the course of operation, if irregular noise or impact is found to be abnormal, stop the inspection immediately.
7. The personnel in the operation should coordinate with each other and listen to the command of the person in charge of the coil. Without a password, it is forbidden to start the machine.
8. When carrying out the coiling operation, it should be very careful that the hand is pressed by the steel plate and rolled together with the steel plate.
9. When lifting the steel plate or reel with the vehicle, be careful not to collide with the machine.
