As the cold season approaches, the use and maintenance of metal processing equipment such as press brakes become particularly crucial. In low-temperature environments, the performance and lifespan of machines may be affected, imposing additional requirements on both operators and the equipment itself during the winter. In this article, we will explore the precautions for using press brakes in winter and provide detailed maintenance guidelines to ensure smooth operation in extremely cold weather conditions.


  1. Temperature Control and Preheating: In low temperatures, the hydraulic system and lubricating oil of the press brake may become viscous, impacting normal operation. Therefore, it is recommended to thoroughly preheat the machine, especially in extremely cold weather, using either the built-in preheating function or external heating devices before starting.

  2. Selection of Hydraulic Oil and Lubricating Oil: Choosing hydraulic oil and lubricating oil suitable for low temperatures is crucial. These oils should have good low-temperature fluidity to ensure adequate lubrication of various machine components in extremely cold conditions. Regularly check the condition of hydraulic oil and lubricating oil and replace them as recommended by the manufacturer.

  3. Anti-freezing Measures: In extremely cold winter conditions, key components of the press brake, such as hydraulic cylinders and valves, may be susceptible to freezing. Using anti-freezing liquids or installing heating devices around the machine can effectively prevent this situation.

  4. Electrical System Protection: The electrical system is vital for the normal operation of the machine. In winter, ensure proper protection of the equipment's electrical system against moisture and freezing. Inspect cables, connectors, and switches regularly to prevent corrosion or damage.

  5. Safety Operation Precautions: Winter weather can lead to slippery surfaces, increasing operational risks. Operators should take precautions for slip prevention, ensuring the safety of the work area. Using cold-resistant work clothes and gloves is recommended to enable operators to work effectively in cold environments.

  6. Regular Inspection and Maintenance: Regularly inspecting and maintaining the press brake during winter usage is particularly important. This includes, but is not limited to, checking hydraulic systems, electrical systems, and mechanical transmission systems. Timely identification and resolution of potential issues can effectively prolong the equipment's lifespan.

Maintenance Guidelines:

  1. Lubrication System Maintenance: Conduct regular checks on the lubrication system, including the lubricating oil tank, lubrication pipes, and oil pump. Clean lubrication points and ensure all components receive sufficient lubrication. Pay attention to the cleanliness of the lubricating oil to prevent impurities from damaging the system.

  2. Hydraulic System Maintenance: Periodically inspect the hydraulic system's pressure, leaks, and seals. Replace hydraulic oil and ensure clear oil passages. Clean the hydraulic oil radiator to prevent excessive oil temperature. Check the working condition of hydraulic cylinders and valves.

  3. Mechanical Transmission System Inspection: Inspect the press brake's mechanical transmission system, including gears, belts, and chains. Tighten any loose components and replace parts as necessary. Maintain the cleanliness of the transmission system and use suitable lubricating oil for effective lubrication.

  4. Electrical System Inspection: Regularly inspect the electrical system's connections, grounding, and switches. Clear snow and ice from the surfaces of electrical components to ensure normal system operation. Replace damaged cables and plugs to prevent malfunctions due to electrical issues.

  5. Cooling System Maintenance: Clean the cooling system, including radiators and fans. Ensure the cooling system operates within normal temperatures to prevent equipment overheating. Check the coolant level and quality to prevent freezing during winter.

  6. Regular Calibration: Conduct regular calibration of the press brake, including the positioning of tools and the level of the worktable. Ensure the equipment maintains high accuracy during operation.

Conclusion: In the cold winter season, the use and maintenance of press brakes require meticulous attention. By following the above precautions and maintenance guidelines, you can ensure that the press brake operates efficiently and safely in extremely cold conditions, extending the equipment's lifespan and providing reliable support for production.
