How to maintain an upper roller plate rolling machine? What are the specific steps?

The upper roller plate rolling machine uses hydraulic transmission for upper roller lifting and horizontal movement, driven by the lower roller, and has a centralized electrical control system. It can complete the pre-bending of both ends of the plate and the rolling of cylindrical and arc-shaped workpieces in one operation. It can also perform certain shaping and leveling of metal plates, offering direct pre-bending, saving time and materials. Equipped with an NC system control, it improves the degree of automation. This machine is widely used in industries with high precision requirements, such as aerospace, nuclear power, and other metal structural component manufacturing, as well as chemical machinery, offshore oil platforms, and oil, gas, and water pipelines.

Hydraulic Plate Rolling Machine Maintenance Procedures

1. Lubricate all oil cups and manual lubrication points as required according to the machine's lubrication diagram.

2. Roll plates according to the parameters specified for the hydraulic plate rolling machine: plate thickness 20mm, maximum length 2500mm, and yield strength of the plate material less than 250MPa.

3. After connecting the power supply, perform forward and reverse movements of the lower roller and lifting/lowering of the upper roller to check for any abnormal jamming or jamming.

4. Strictly follow the hydraulic plate rolling machine's plate rolling processing procedure and operating methods. Pay close attention to the safe operation of the equipment when the upper roller is raised or lowered to its limit position.

5. Only after the main drive has stopped can the upper roller be raised or lowered, the tilting bearing reset, and the upper roller tilted.

6. During operation, if irregular noise, impacts, or other abnormal phenomena are observed, stop the machine immediately for inspection.

7. During operation, all personnel must coordinate with each other and obey the instructions of the person in charge of plate rolling. Do not start the machine without a command.

8. When operating the hydraulic plate rolling machine, be extremely careful not to let your hands be trapped under the steel plate or rolled into it.

9. When using a crane to lift steel plates or rolls, be careful not to collide with the machine.

After the hydraulic plate rolling machine finishes rolling, ensure that all materials are used up and the site is cleaned, and perform maintenance on the equipment, and turn off the power in a timely manner.
