maintenance and maintenance of press brake : what are the benefits? how to proceed?
Press brake are powerful tools used to bend, cut and shape different materials, and they require regular maintenance and maintenance to keep them in good working condition. Proper maintenance is a necessary condition to ensure the life and safe operation of the machine, regular inspection and cleaning can improve the function of the machine and prevent premature failure of components. This paper discusses the importance of maintenance in the press brake and the main components that need to be maintained.
The importance of regular maintenance
The importance of regular maintenance cannot be overemphasized.
As we all know, the service life of the press brake depends on the quality of the product, but also depends on the user's maintenance measures. Regular maintenance is not only necessary to extend the life of the press brake, but also to eliminate failures, reduce the rate of workpiece damage, and the potential danger to the operator. The enterprise should develop a detailed regular maintenance plan and record it in the form of a table, and the press brake operators and maintenance personnel need to be professionally trained.
Regular repair and maintenance can find the failure of the press brake in time to avoid expensive maintenance costs.
Benefits of bender maintenance
There are many benefits to maintaining a bender, including:
1) Improved safety: Regular maintenance reduces the risk of accidents and machine failures that can cause injury to operators and equipment.
2) Increase productivity: Proper maintenance ensures efficient operation of the machine, reduces downtime and maximizes productivity.
3) Reduce maintenance costs: Regular maintenance helps detect minor problems early, avoiding costly repairs and time-consuming downtime.
Maintenance of press brakes helps to extend service life and reduce costs. The maintenance of press brake is mainly divided into several parts, including hydraulic system, mechanical part, lubrication, electrical equipment, tooling, etc. The daily maintenance of press brakes is trivial, but relatively simple. Once the daily overview process is complete, specific maintenance tasks can be handled.
This paper will introduce several important aspects of press brake maintenance.
1. Get a full checkup
Check the overall condition of the brake machine before using it.
Check the processing area and work surface for residues; Check whether there are defects and cracks in the upper and lower molds, if there are cracks in the molds, it will affect the bending quality of the workpiece; Test the accuracy of the position of the rear gauge and stop finger.
In addition, testing whether all buttons, switches, indicators and foot controls are touchable and some important components require special maintenance is a routine check item before each use of the press brake machine.
2. Hydraulic circuit
The hydraulic system is the most critical component in the press brake, and it is checked and inspected regularly to ensure that the system is leak-free, the hydraulic oil is clean, and the system is adequately cooled. Hydraulic oil is the energy source of the hydraulic system, so it is important to keep the oil circuit and hydraulic circuit clean.
The hydraulic circuit includes fuel tank, valve group, pipeline, motor, oil pump, etc. When cleaning valves, fuel tank caps and related accessories, it is not recommended to use detergent. In addition, visually check whether the oil level in the tank is within the safe range every day, otherwise it will affect the work of the hydraulic pump, resulting in insufficient power to drive the ram. Also, make sure the tank is well sealed and well ventilated, but the tank is not completely sealed and a breathing apparatus is needed to prevent the tank from creating a vacuum. The seal is designed to prevent particles from entering the tank and contaminating the oil, which can clog the valve and damage the hydraulic pump, thus affecting the operation of the hydraulic system.
3. Hydraulic accessories
Check all pipes and hoses for leaks, especially hydraulic pumps and connection accessories, such as tubing expansion, aging or pipe wear, should be replaced in time.
Check the cylinder assembly, valves, and hydraulic blocks for leaks, and if there is too much oil on the piston, wipe it clean and lubricate properly.
Check pump and safety valve maximum pressure.
4. Clean the fuel tank and filter
Before replenishing the oil, it is necessary to clean the tank and filter.
To clean the filter of the oil pump inlet and outlet holes, the air breathing apparatus on the tank needs to be cleaned with compressed air. Filters and air brewers need to be replaced after reaching a certain service life. The oil temperature should not exceed 60 degrees, otherwise it will affect the stability of the oil and damage the parts.
5. Cleanliness and level of oil
Use the manufacturer's recommended oil type to ensure the cleanliness of the oil.Check the oil level in the tank every day, and fill the oil with an electric pump, and check the quality and viscosity of the oil every 4000 to 6000 hours.
6. Mechanical parts
Regular inspection of mechanical components is necessary to ensure the stability of all components.
The mechanical system of the press brake must be lubricated regularly to ensure its smooth operation. All moving parts, including bearings, gears and guides, require regular inspection and thorough cleaning, and replacement of worn parts to avoid costly repairs.
It is important to regularly tighten all bolts, nuts and screws and check the connection between the piston and ram. Check the joint of the base for cracks, and check whether the rear gauge and stop finger are intact.
It needs to be recalibrated if needed.
7. Lubrication system
The lubrication of the press brake parts is an important factor in extending the service life of the machine. Lubrication is essential to ensure the smooth and efficient movement of the parts of the machine and to reduce the wear of the parts.
Some parts of the press brake are affected by sliding, rolling or friction. Lubrication can reduce friction and damage to parts, and parts that need regular lubrication and cleaning include ball screws, guides, back gauges, gears, etc. These parts should be lubricated at least once a week, some parts may even need to be lubricated every day, and it is important not to over-lubricate. Because this can lead to insufficient friction or component contamination, be sure to clean all parts and use the manufacturer's recommended lubrication products before using lubricants or greases.
8. Electrical equipment
The maintenance of electrical equipment is the most important thing to extend the service life of the press brake. The electrical connection should be checked regularly to ensure that it is not loose, short circuit and no wear. If there is wear or damage, it should be repaired in time to avoid safety hazards
Check the entire electrical system, including all electrical connections and switches, at least once a year. Before the inspection, the main power switch must be turned off, and other checks can be carried out after the power is turned on.
When assembling electrical parts, keep them clean and safe.
Check the connection status of the terminal box and terminal band on the monitor and relay;
Check that all wires are loose, the insulation is damaged, the wires are clean and orderly, if the wires are loose, tighten them, and then clean them with a clean cloth or compressed air.
Check the filter of electric control cabinet and inverter box, clean with compressed air;
Check all cables, printed circuit boards, switches, if damaged or faulty, repair and replace;
Check whether the limit switch and voltage are in good condition, and keep the cooling fan and heat exchanger filter clean and working normally;
Check whether the outer panel of the power box is turned off, and whether the switch and indicator functions of the power box are normal.
9. Tool system
The press brake machine used to bend different metal plates, the correct maintenance of the machine tooling, including calibration and maintenance, to ensure the precision and accuracy of material processing.
The machine's press and mold will be in direct contact with the plate, so the material of the mold is particularly important, and the material of the workpiece also needs to be considered, because the material with rolling chips will wear the mold.
After use, the punch and die need regular maintenance to avoid rust and corrosion. After each use, wipe the punch and die with a clean lint-free towel and alcohol, this is done to eliminate fingerprints, as the pH of the hand will corrode the die surface, then put on gloves and apply an anti-corrosion lubricant to the die. Finally, put them into the toolbox and place at least one bag of silicone in it, which will need to be replaced if the punch or mold is damaged.
Conclusion
Maintaining the press brake is essential for its longevity and safe operation, while maximizing its productivity. Press brake maintenance includes hydraulic circuits, hydraulic accessories, tooling systems and electronic accessories. In addition, lubrication of mechanical components, guide rails, rear gauges, shafts, ball screws and other components is necessary, as well as the cleaning of the foundation. By following the manufacturer's guidelines for regular maintenance, the operator can enjoy the full benefits of the machine and prevent any costly breakdowns that can be avoided with proper maintenance, maintaining a safe working environment is Paramount.
