During the operation of cold bending equipment, it is crucial to pay special attention to maintenance and care. This ensures the equipment operates smoothly, thereby not affecting normal production and also extends the equipment's lifespan.

1. Maintenance and care for rolling mill rolls. It is essential to apply anti-rust oil to the rolls approximately every ten days. Additionally, when the equipment is planned for extended non-use, the rolls should also be coated with anti-rust oil.

2. Maintenance and care of cutting die molds. In the production process, add lubricant every half-hour to the areas of friction on the cutting die to prevent accelerated wear and tear. Additionally, if it is observed that the burrs on the wounds are too large and not in accordance with regulations, it is due to the blade being insufficiently sharp. Proper handling is required; otherwise, the blade head or mold may be damaged. For practical methods to make the cutting die sharper, please refer to: What are the methods for cold bending edge treatment?

3. Maintenance and Care for Piercing Molds. The maintenance concept for piercing molds is similar to that for cutting dies. When the mold is found to be insufficiently sharp, it must be flat-ground to enhance its sharpness.

4. Maintenance and Care of the Transmission Mechanism. For cold bending machines, the friction in the transmission mechanism is quite severe. By transmission mechanism, we refer to components such as chains, gears, and reducers. This area experiences accelerated wear and tear due to high wear and long-term operation. Therefore, special attention should be paid to lubrication solutions for these locations. During operation, lubricate the connections and gears every half hour, and check the oil level in the reducer approximately every ten days. The amount added should be based on the actual situation, ensuring the oil level is maintained at about two-thirds.
