Automatic four-high plate rolling machine is a bending and correcting machine for sheet metal. Special for sheet metal forming and bending work. The pre-bending and crimping of various types of cylindrical and curved workpieces can be completed after one feeding. With the aid of auxiliary devices, the conical cylindrical body can be rolled. Rough shaping of sheet metal can also be done. We should operate in accordance with the normal rules and regulations when using the fully automatic four-high plate rolling machine:

1. Operators should understand the structure and performance of the four-roll plate rolling machine, be familiar with the operation method of the control system and the bending process of the workpiece, and strictly observe the safe operation matters.

2. All buttons of the electronic control system must be placed in the original position before starting and stopping.

3. In case of irregular noise, impact, swing or oil leakage during operation, stop immediately for inspection and repair.

4. In the process of use, the transmission mechanism and connecting parts should be frequently checked to keep no loosing and no damage.

5. In the rolling process, the plate must roll along with the upper and lower rollers, and no slipping phenomenon is allowed.

6. During the rolling process, the supporting roller can be lifted only when the upper and lower rollers are clamped on the steel plate.

7. In the equipment rolling process, the lower roll and the side roll are not allowed to rise and fall at the same time.

8. During the operation of the equipment, the operator should stand on both sides of the workpiece. It is strictly prohibited to stand on the workpiece and find the right roundness on the cylinder that has been rolled.

9. The equipment must be used within the capacity of the equipment, and overload is not allowed.

10. When operating the equipment, hands and feet are strictly prohibited on rollers, transmission parts and workpieces. After the work piece enters the roll, should prevent the human hand and the clothing to be caught in the roll.

11. The work site shall not be piled up with work pieces and sundries, and the machine tools and the site shall be kept clean at all times.

12. Unloading is carried out when the lower and side rolls drop to a certain position, the head is turned to 85 degrees, and the upper roll is raised.

13. After the completion of the operation, the power should be cut off and the power box should be locked.

14. The hydraulic transmission system should be checked regularly, and the failed hydraulic components should be adjusted and replaced timely.

15. The oil tank shall maintain the specified oil level to minimize the pollution of hydraulic oil, check the deterioration of hydraulic oil at least half a year, and replace it in time if it exceeds the requirements.

16. All live parts of the electrical system should be properly grounded, electrical components should be checked regularly, dust removal, timely replacement of damaged and invalid components. Each solenoid valve, limiter should often check and adjust.
