1. Overhaul of the air supply system: Once the air supply system leaks, the air pressure will inevitably decrease, which will cause some poor pneumatic actions. Therefore, always check and replace the seals, and keep the air piping normal. In addition, too much moisture in the air will cause the machine to rust and cause the solenoid valves and various cylinder pistons to operate poorly. Therefore, attention should be paid to the dehydration equipment near the equipment at the initial end of the air supply pipe, and always check the protection.

2. Maintenance of the oil supply equipment: The relative rotation and sliding of the presses will cause burns and malfunctions if the oil supply is lacking. Therefore, you should always check the fuel supply status carefully to make it stand out. Firstly, check whether the fuel tank, tank, oil cup, pump, etc. are sufficient and have no dirt; secondly, check whether there is any oil leakage at the oil filling parts, oil pipes, and joints. If there is oil leakage, replace the seals immediately. Once the leaked oil adheres to the clutch or brake, it will affect its function and pose a risk, so special attention should be paid. In addition, the finishing of the oil filter, the replenishment of the lubricator installed in front of the solenoid valve, and whether the dripping amount of the lubricator is appropriate are all items that cannot be lost.

3. Protection of clutches and brakes: To ensure smooth and accurate actions of clutches and brakes, it is necessary to adjust the clearance of the conflict disc. If the gap is too large, the action time will be delayed, the seals will wear out, and the air demand will increase, which will cause adverse effects; if the gap is too small or the gear spline shaft of the conflict disc will not slide well, the return spring will be damaged, etc., which will cause the clutch and brake to be disengaged. The conflict discs collide with each other, and the sound of conflict occurs, which causes heat generation and wears out the conflict disc, and the current value of the main motor becomes larger. The clutch and brake actions must be accurate, and the error of the designated stop position should be within ±5°. If it exceeds, it is necessary to adjust. At this time, you should check: whether the brake conflict disc is worn or not, whether the action is not good; whether the clutch and brake conflict disc are attached to oil; whether the cylinder piston seal is worn or leaked; whether the air pressure can change; the interlocking timing of the brake and the clutch can be Whether to be disrupted. Therefore, it is necessary to check and repair the operating circuit, rotary cam switch, solenoid valve and air source of its actions.

4. Overhaul of tightened bolts: Through long-term use or overload, the tightened bolts will become loose. To determine the appearance of looseness, as long as the press bears the load, it is enough to investigate whether the contact surface between the base of the frame and the column can have an oil balance. There is an oil balance, indicating that the tightening bolts are loose. It is very risky to operate the press with the tightening bolts loose, and it is necessary to tighten it from the beginning. The amount of tightening can be determined by referring to the description of the description.

V. Correction of other loose bolts: Whether some bolts (including equipment bolts of subordinate equipment) can be loosened is also a matter that should be checked regularly. If there is any looseness, it should be tightened immediately. The electric screw press is used for stamping operation, and the oscillation is large, especially the high-speed press, the oscillation frequency is high, and the bolt loosens quickly. Loose bolts often lead to unforeseen incidents, and it is necessary to treat them carefully.

6. Regular inspection and repair of transmission system, electrical system and various auxiliary equipment functions. Normal inspection is an important part of regular maintenance and protection. It can prevent problems before they happen. Therefore, it is necessary to include the press operating procedures. Before daily operation, during start-up processing, and after operation, check the corresponding items in order to find problems in time deal with.

Seven, timing accuracy check: With the continuous use of time, the accuracy of the press is also decreasing. Therefore, the accuracy should be checked regularly and the accuracy is found to be reduced, so that it can be recovered as soon as possible to avoid affecting the accuracy of the stamping product and the life of the mold. The usual low requirements for presses are that after the accuracy is reduced by one level, it is necessary to correct and recover as soon as possible, which is also convenient for subsequent quality management.
