Slitting lines are commonly used in the machining industry. Although the slitting line is of good quality, it is inevitable that there will be failures during use. Let's take a look at the faults that are prone to occur in the slitting line.

When using slitting lines, we should observe the following precautions:

1. When rolling a narrow cylinder, it should be placed in the rolling center.

2. After the workpiece enters the slitting line reel, you should avoid rolling your hands and clothes into the reel.

3. The workpiece must be placed smoothly and can only be started after it is in place. The signal should be clear, and one person should be appointed to command.

4. Do not put your hands on the rolled steel plate, and it is forbidden to use the template for inspection. After the machine is stopped, check the roundness with the template.

5. When the pressure of the rolled workpiece is insufficient, when rolling to the end of the steel plate, please reserve a margin to prevent the workpiece from falling and hurting people.

6. During the working process, it is forbidden to stand on the workpiece or find the roundness on the rolled cylinder.

7. When rolling large diameter cylinders or high data strength workpieces, some moving rolls should be reduced and repeated.

Don't worry when the slitting line has problems during use. Stop the slitting line first, check which parts have problems, and then take appropriate action to solve the problem.

Generally, the slitting line is running most of the time, but it is necessary to interrupt the oil temperature drop of the slitting line and the cooling effect of each component when it is resting. If the installation of the slitting line does not meet the technical specifications, it is easy to cause sealing leakage, the safety protection effect cannot be guaranteed, and even accidents may occur.

Valve oil leakage is usually caused by a clogged or damaged valve, and the valve should usually be replaced. Check the upper cylinder and port to make sure the slitting line has no gaps. Some oil seals are used for too long and will lose elasticity due to rubber aging. In this case, the failed oil seal needs to be removed as soon as possible.

In addition, other problems may occur: incorrect installation of many moving parts on the automatic slitting line; misalignment of the journal with the center of the oil seal edge; prevention of blockage of the check valve and exhaust valve; increased temperature in the slitting line tank, oil and gas The entire space cannot be discharged, the pressure in the fuel tank increases, the consumption of lubricating oil increases, and the cycle is shortened.

During the maintenance of the slitting line, due to the dirt on the contact surface is not cleaned, the sealant is improperly selected, the sealing direction is reversed, and the seal is not replaced as soon as possible, oil leakage may occur. Due to the interference of the air pressure difference inside and outside the casing, the oil leakage of the soft seal often occurs. Therefore, it is necessary to regularly check, unblock and clean the hydraulic press.
