The Guide to Coil Straightener Maintenance

Coil straightening machine is play an important role in metal processing. Without them to level materials, subsequent shearing or stamping operations would become difficult. Over time, straightening machines may experience minor malfunctions that impact production efficiency and quality. Therefore, learning how to maintain straightening machines is essential. This not only extends their lifespan but also ensures their leveling performance.

1. Simple Check

The simplest way to maintain a machine is to look and listen. Surface problems are the easiest to spot. We can do a simple check: operation buttons and external parts. Press to check if the operation buttons work properly. Check for loose parts, abnormalities on the rollers, and listen for any unusual noises while the machine is running.

2. Cleaning

When the rolled stock is leveled after being unrolled, it is usually the oiled material that is being processed. After a long period of leveling work, some oil will remain in the rollers of the straightening machine. Failure to clean these oil stains promptly can cause material slippage and deviation during straightening, resulting in uneven leveling. If the oil remains for an extended period, dust and impurities may mix into the oil, increasing straightening resistance. In severe cases, it can even corrode the leveling rollers and cause the chrome plating to peel off. All of these factors affect the straightening effect. To solve this problem, regular cleaning is essential. Some leveling machines can open the upper working rollers, which will make it easier to clean.

3. Lubrication



To maintain stable leveling power, we need to pay attention to the maintenance of the drive system. For example, in some gear-driven machines, we can regularly add lubricating oil to the gear sets and universal joints to keep them running smoothly. Roller bearings are also parts that require lubrication. We can consult the manufacturer for lubrication solutions to learn more about the details.

4. Check Power Supply

Power supply is a crucial source of power; a malfunction will render the leveling machine inoperable. We should regularly inspect the power lines for aging or damage and address any issues promptly.

5. Check Hydraulic System

The hydraulic system provides the powerful pressure needed for the screed machine to press down and level, playing a vital role in the screeding process. To inspect the hydraulic system, check the remaining oil in the tank for leaks. Regularly clean the tank of deposited impurities and replace the hydraulic oil. Check for normal pressure.

6. Check Manual adjustment device

The leveling machine's adjustment device is mainly used to adjust the vertical spacing of the rollers according to different materials. At all times, we should perform a precision calibration to check its proper functioning and accuracy. If a precision calibration has not been performed, but the deviations in accuracy occur, we may unknowingly obtain an unsatisfactory leveling result.
