Operation problems and precautions of cnc hydraulic four roll plate bending machine
We found that many customers are very good at using the bending machine, but they are at a loss once there is a problem and don’t know what to do. If we can understand or even master some common sense about the normal operation of the bending machine, we can easily solve this problem. How to judge whether the bending machine is normal?
First, turn on the coiler. When the coiler is idling, the noise pressure level shall not exceed 90dB. When gear transmission, electrical and hydraulic components work, there shall be no irregular impact sound and periodic squeal. Try to make the mechanical transmission system operate normally, stably, without abnormal sound, and brake sensitively and reliably. Then check the hydraulic components and pipelines to ensure that there is no leakage.
During the operation of the plate rolling machine, the oil temperature in the oil tank shall not exceed 50 ℃ when the hydraulic system of the plate rolling machine is working. After 4 hours of continuous full load operation, the oil temperature in the oil tank shall not exceed 60 ℃. The hydraulic transmission parts shall be free from vibration creeping, stagnation and significant impact within the working range. The amplitude of no-load operation shall not exceed 30 μ m。

Causes of heating of plate rolling machine:
- The pressure regulation is too high, which makes the speed of the plate rolling machine become fast, thus causing the seal ring and side plate to burn out;
- The oil tank of the plate rolling machine is too small, resulting in poor heat dissipation conditions;
- Internal leakage caused by excessive axial clearance or damaged seal ring.
The bending machine will break down after being used for a period of time, so it needs to be maintained in daily production to extend its service life:
- Operate in strict accordance with the operating procedures.
- The rolling machine must always be kept clean, and the unpainted part of the anti rust grease must be kept clean.
- Before each startup, add lubricating oil regularly, fixedly and quantitatively according to the requirements of the lubrication chart, and the oil should be clean and free of sediment.
Precautions for operation of Wuxi Shenchong cnc hydraulic four roll plate bending machine
cnc hydraulic four roll plate bending machine is a kind of public forging machine and equipment that can bend non-metallic plates into cones, spheres, cylinders or other shapes. This performance has been widely used in industries such as production, boiler steam, chemical industry, non-metallic structures and machine building. Next, we will introduce the precautions when folding the lower cnc hydraulic four roll plate bending machine.
- Four roll bending machine shall be managed by specially assigned person.
- The operator shall be familiar with the structure, performance and use method of the cnc hydraulic four roll plate bending machine, and shall not operate until approved by the responsible manager.
- Before starting the machine, carefully check whether the device is in good condition.
- During operation, it is strictly forbidden to put hands and feet on rollers, transmission parts and workpieces.
- After the work is interrupted, the clutch shall be set to neutral.
- Multi person cooperation shall be commanded by a specially assigned person.
- Overload is strictly prohibited.
- The tilting and resetting of the upper roll lifting and turning bearing and the balancing of the upper roll must be carried out after the main drive stops.
- It is forbidden to pile up workpieces and sundries in the work site, and the machine tool and the site shall be kept clean at all times.
- After operation, cut off the power supply and lock the power box.
The above are the precautions for the operation of the cnc hydraulic four roll plate bending machine. I hope these contents can help you.
