The maintenance of punching machines first requires regular cleaning of the equipment. Remove dust, debris, and other foreign objects from the surface and interior of the equipment to prevent them from entering the mechanical transmission components and affecting the operation of the equipment. For transmission components such as guide rails, screws, gears, etc., lubricating oil should be applied regularly to reduce friction, prevent wear, and extend service life. The hydraulic system of the hydraulic punching machine should be regularly checked for the quality and quantity of the hydraulic oil. If the hydraulic oil deteriorates or is insufficient, it should be replaced and replenished in a timely manner. The mold is a key component of the punching machine. After each use, the residue on the surface of the mold should be cleaned, and the mold should be checked for wear, cracks, and other conditions. If there are any problems, they should be repaired or replaced in a timely manner. Regularly inspect the electrical system of the equipment to ensure that the circuit connections are secure and free from short circuits, leakage, and other phenomena. In addition, develop a reasonable equipment usage plan to avoid long-term overload operation of equipment, keep daily operation records of equipment, and facilitate timely detection and handling of potential problems.
