W12 Plate Rolling Machine

We are a professional plate rolling machine manufacturer with over 10 years of industry experience. Today, we would like to introduce to you the maintenance cycle of the plate rolling machine and the depth analysis of key maintenance points:

As the core equipment for sheet metal processing, the operation status of the coiler directly affects the processing accuracy, equipment life and production efficiency. Reasonable maintenance can not only reduce the sudden failure, but also avoid the decline of plate forming quality caused by equipment wear. As the coiler is subjected to large loads in the operation process, the mechanical parts are prone to fatigue, wear and tear or loosening, so it is necessary to establish a scientific maintenance system to ensure the long-term stable operation of the equipment.

The basis for the development of maintenance intervals

The maintenance cycle of the coiler is usually determined according to the frequency of use of the equipment, the characteristics of the processed material and the working environment and other factors. High-frequency, high-load operation of the equipment needs to shorten the maintenance interval, while intermittent use of the equipment can be appropriate to extend the maintenance cycle. Generally speaking, maintenance can be divided into routine maintenance, regular maintenance and long-term maintenance of three levels to ensure that the key components of the equipment is always in good condition.

Key Points for Daily Maintenance

Daily maintenance is the foundation of roll forming machine maintenance. It is mainly carried out by operators before and after daily operations and includes the following:

Lubrication System Inspection

The guide rails, gears, bearings, and other moving parts of the roll forming machine must be kept well lubricated. Before daily operations, check that there is sufficient lubricating oil and that the oil passages are unobstructed to prevent abnormal wear due to poor lubrication.

Critical Fastener Inspection

Under prolonged vibration, bolts, nuts, and other fasteners may become loose. Daily inspections of critical areas such as rollers, frames, and transmission systems are required to prevent loosening from affecting equipment accuracy or causing safety incidents.

Hydraulic and Electrical System Inspection

Inspect the hydraulic system for leaks and stable oil pressure; check electrical circuits for damage and ensure control buttons are responsive to prevent equipment malfunction due to electrical faults.

Cleaning and foreign object removal

Metal debris generated during processing may enter the transmission system and affect equipment operation. After daily operation, clean the surface and interior of the equipment to remove any remaining debris and keep the equipment clean.

Key points of regular maintenance

Regular maintenance is usually performed on a weekly, monthly, or quarterly basis by professional maintenance personnel, focusing on checking wear parts and key structures, mainly including:

Roll Shaft and Bearing Inspection

The roll shaft is the core component of a roll forming machine and directly affects the forming quality of the sheet metal. Regularly inspect the roll shaft surface for scratches, wear, or deformation, and check whether the bearings are operating smoothly. Replace or repair them as necessary.

Transmission System Maintenance

This includes inspecting transmission components such as gears, chains, and belts for wear, adjusting transmission clearances, ensuring smooth power transmission, and preventing equipment stalling or reduced precision due to transmission failure.

Hydraulic System Maintenance

Regularly replace hydraulic oil, clean filter elements, check cylinders, valves, and pipes for leaks, ensure stable hydraulic system pressure, and avoid equipment performance issues caused by oil contamination or pressure fluctuations.

Electrical System In-Depth Inspection

Check the working status of electrical components such as motor carbon brushes, contactors, and relays, test the response speed of the control system, and prevent malfunctions or shutdowns caused by electrical aging.

Long-term maintenance and replacement of key components

Long-term maintenance is usually carried out every six months or every year, mainly focusing on systematic inspection and replacement of key components of the equipment, including:

Structural component fatigue testing

Long-term load operation may cause fatigue cracks or deformation in structural components such as frames and support seats. Their safety must be assessed through professional testing methods (such as ultrasonic flaw detection), and reinforcement or replacement must be carried out when necessary.

Replacement of critical bearings and seals

Bearings, oil seals, and other components will gradually age after long-term use, leading to lubrication failure or oil leakage. They should be replaced according to the cycle recommended in the equipment manual to avoid sudden failures.

Control system upgrade and calibration

For CNC plate rolling machines, data drift or control accuracy degradation may occur after long-term use. Sensors and servo systems should be calibrated regularly, and software should be upgraded when necessary to ensure processing accuracy.

Maintenance Records and Management Optimization

Scientific maintenance management requires a comprehensive record-keeping system. After each maintenance operation, detailed records should be kept of the items inspected, parts replaced, and parameters adjusted so that trends in equipment status can be tracked. At the same time, maintenance cycles should be optimized based on equipment operating data to improve maintenance efficiency.

Maintenance of rolling machines is a systematic task. A reasonable maintenance cycle and key point checks can effectively extend the service life of the equipment and ensure processing quality. Daily maintenance focuses on prevention, regular maintenance focuses on wear control, and long-term maintenance ensures the overall performance of the equipment. Only by establishing a scientific maintenance system can the processing capacity of rolling machines be maximized, the risk of failure be reduced, and production efficiency be improved.
