Environmental factors such as high temperature, humidity, and heavy rain in summer can easily affect the normal operation of bending machines and shearing machines, increasing the risk of equipment failure. To ensure production safety and extend the life of the equipment, please strictly abide by the following use and maintenance specifications.
一、 General precautions (applicable to bending machines and shearing machines)
1. Temperature control and heat dissipation management
Keep ventilation: Keep good ventilation around the equipment to avoid direct sunlight. Install exhaust fans or air conditioners to cool down if necessary.
Check the electrical system: High temperature can easily cause electrical components to overheat. Regularly check the heat dissipation of the electric control cabinet, motor, inverter, etc. and clean the dust.
Hydraulic system monitoring: It is recommended to control the hydraulic oil temperature of the bending machine below 60℃. If it is too high, stop the machine for cooling or replace the summer special hydraulic oil (such as ISO VG46).
If the shearing machine is hydraulically driven, check the oil circuit sealing to prevent the oil from thinning and leaking due to high temperature.
2. Moisture and rust prevention measures
Control the humidity in the workshop: A humid environment can easily cause the equipment to rust. It is recommended to use a dehumidifier or place a desiccant.
Lubrication of key parts: The bending machine guide rails, lead screws, shearing machine tool holders, slide rails and other parts need to be checked daily and applied with high-temperature resistant grease or anti-rust oil.
When the machine is stopped, the surface of the equipment can be covered with moisture-proof cloth to avoid corrosion from condensed water.
3. Safety operation specifications
Personal protection: Operators need to wear breathable work clothes and non-slip gloves to avoid operating errors due to sweating.
Equipment inspection: Check whether the hydraulic system, electrical circuits, and safety protection devices (such as emergency stop buttons and safety gratings) are normal before starting.
Avoid long-term overload operation to prevent motor overheating or abnormal hydraulic system pressure.
Heatstroke prevention measures: Arrange working hours reasonably in hot weather, provide cool drinks, and prevent heatstroke.
二、Special precautions for bending machines
1. Mold and sheet material management
Anti-rust treatment: Clean the mold in time after use and apply anti-rust oil to avoid rust caused by humid environment.
Plate inspection: The air humidity is high in summer, and the plate is easy to oxidize. Before bending, clean the surface moisture or rust to prevent scratching the mold.
2. Hydraulic and electrical systems
Replace hydraulic oil regularly: High temperature will accelerate oil oxidation, so it is recommended to shorten the oil change cycle (such as every 3 months or as required by the manufacturer).
Check seals: High temperature can easily cause rubber seals to age, so replace them in time if oil leaks are found.
三、Special precautions for shearing machines
1. Blade maintenance and adjustment
Anti-rust treatment: Clean the blade after use and apply anti-rust oil to prevent rust from affecting the cutting accuracy.
Check the blade gap regularly: High temperature may cause metal expansion, and the blade gap needs to be adjusted to ensure the cutting quality.
2. Transmission system lubrication
Check the gearbox/chain: High temperature may make the grease thinner, so use high temperature resistant grease and increase the frequency of lubrication.
四、 Maintenance plan
Hydraulic oil inspection: Check the oil quality and oil temperature every 2 weeks; the same for hydraulic shearing machines.
Lubrication point maintenance: Check the guide rails and screw lubrication daily; the shearing machine checks the tool holder and slide rail lubrication daily.
Electrical system inspection: Clean the dust in the electric control cabinet every week; the same for shearing machines.
Anti-rust treatment: Cover with moisture-proof cloth when shutting down; the same for shearing machines.
五、 Emergency Response
Equipment overheating alarm: stop the machine immediately, check the cooling system, and restart after cooling.
Hydraulic oil leakage: stop the machine for inspection, replace the seals, and clean the oil to avoid fire hazards.
Electrical failure: disconnect the power supply and have a professional electrician check it to avoid self-disassembly and repair.
Summary
When using bending machines and shearing machines in summer, it is necessary to focus on cooling, moisture prevention, lubrication, safety inspections, strengthen daily maintenance, ensure stable operation of the equipment, and ensure the safety of operators.
