Based on Primapress technical standards and professional manufacturing experience, this article presents standardized guidelines and in-service maintenance specifications for power presses. It covers routine upkeep and safe operating procedures to stabilize equipment performance and eliminate potential production risks.
Maintenance Guidelines
- Safety Regulations：Ensure the correct locking/opening process to ensure the safety of maintenance personnel, and ensure that the sleeve is placed at the bottom of the travel before performing brake maintenance work. If this is done, there is no need to lock the sleeve anymore.
- Operator Collaborative Maintenance：Adding press operators to the maintenance process of the press can enable them to alert maintenance or management personnel at any time when problems arise. They operate the press every day, making it easier to hear or see signs of problems. Just as driving the same car every day can immediately notice abnormal noises, the same applies to operators.
- Environmental & Cleaning Management：A clean pressure machine allows operators or maintenance personnel to quickly detect problems when they occur. For example, oil leaks, air leaks, fractures, etc. If the press is clean, its location can be easily identified.
- Electrical System Maintenance：Only qualified electrical technicians can perform electrical circuit maintenance on the press, but you can still check whether the light bulbs on the press control panel are normal. Every shift should ensure that the light bulbs are working and correctly display the various operating conditions of the press.
- Pneumatic & Balance System Maintenance：Precisely balanced presses perform better and require annual inspections. Check pneumatic systems for leaks; improper air pressure impairs brakes and balance units that control stopping time, posing risks to operators and equipment. Drain water from pneumatic regulators, lubricators and pipelines daily.
- Lubrication & Filter Replacement：Poor lubrication maintenance often leads to press downtime. Operators frequently neglect timely filter replacement for circulating oil systems. Replace filters together with oil and carry out frequent replacements routinely.
Key Maintenance Points
What aspects are important for the daily maintenance of a mechanical press? The answer is the operator. All maintenance and problem identification of the power press punching stamping machine begins with the operator, who often discovers problems early on to prevent significant and sustained damage to the power press punching stamping machine components.
The operator can pay attention to the strange noises made by the press; Abnormal temperature rise, smoke, debris or metal particles appearing in certain parts; And the leaking pipeline was found to have problems. Operators should ask themselves some questions every day, record their answers after inspection, and maintain long-term maintenance records.
Operational Maintenance and Upkeep of Power Press Machine
Comply with standard punching and forming procedures. Assign dedicated operators for team operation. Equip exposed transmission parts with guards and prohibit unguarded operation. Install molds properly at bottom dead center within rated stamping force. Concentrate on manual parameter adjustment. Ban interlayer stamping and mold-area body access, perform regular mold inspection and calibrate motor speed for different workpieces.
Before work
Before starting work, check whether the punch punching press stamping machine protection device is complete and whether the flywheel runs smoothly; Is there any protection on the upper and both sides of the foot pedal device, and is the operation reliable and flexible; And remove any objects that obstruct operations in the workplace.
- Check the lubrication condition of each part and ensure that each lubrication point receives sufficient lubrication
- Check if the mold installation is correct and reliable;
- Check if the compunching press stamping machineed air punching press stamping machineure is within the specified range
- Check whether each switch button is sensitive and reliable. It is necessary to disengage the flywheel and clutch before starting the motor;
- Perform several empty strokes on the punching press stamping machine, check the working condition of the brake, clutch, and control parts
- Check the main motor for abnormal heating, vibration, sound, etc
- Add lithium based ester oil to the slider using a manual oil pump
- Check and adjust the gap between the feeder rollers to meet the process requirements
- Check and maintain the oil level of the oil mist device to meet the specified requirements
- When the motor is started, it should be checked whether the direction of rotation of the flywheel is the same as the rotation mark.
At work
Attention should be focused during work, and it is strictly prohibited to insert hands, tools, or other objects into the danger zone. If abnormal operation or abnormal noise is found in the punching press stamping machine (such as knocking or bursting), the feeding should be stopped and the cause should be checked. After each workpiece is punched, hands or feet should be removed from the button or pedal to prevent accidental operation.
- The manual lubricating oil pump should be used regularly to supply lubricating oil to the lubrication points
- Do not adjust the punching press stamping machine without prior knowledge of its performance
- It is prohibited to simultaneously punch two layers of board material
- If abnormal work is found, work should be stopped immediately and checked in a timely manner.
After work
Before leaving work, the mold should be placed against the ground, the power should be disconnected, and necessary cleaning should be carried out.
- Release the flywheel and clutch, cut off the power, and release the remaining air
- Wipe the punching press stamping machine clean and apply rust proof oil to the workbench
- Make records after each operation or maintenance.
Conclusion
Standardized operation and scientific daily maintenance ensure the stable and safe operation of power presses. Complying with safety rules, performing regular inspections and eliminating potential faults can reduce failure rates, extend equipment service life, and guarantee personal and production safety.
