Today's hydraulic press brakes are offered in a broad range of capacities,following these six steps can make a significant difference in bending performance, wear and tear of system components, and the lifespan of the press brake.
1. Take a Look Around
Verify that the hydraulic press brake is in clean condition. The table and die area should be free of mill scale, the punch and die alignment and inspect the tooling's condition. The actual position of the backgauge fingers should be checked and should match the readout value for the corresponding axes. Also verify the proper operation of all devices, including palm buttons, up button, e-stops, foot pedal control, and indication lights.
2. Take Precautions
The press brake ram always should be supported before performing any maintenance work on machine hydraulics or the mechanical system. To do so, place the ram on two equal size wooden blocks or lower the ram, supported by the tooling.The electrical system should be locked out to ensure it cannot be engaged.
3. Check out the Hydraulic Circuit
Check the oil level in the tank periodically. If the press brake is equipped with a hydraulic tool clamping system for punch and die clamping, also check this oil level periodically. Problems and irregularities in the operation of the pump and valves may occur if dirt is present in the oil. Every 2,000 hours of operation, check the quality and viscosity of the oil. To do so, obtain an oil sample and have your oil supplier analyze it. The supplier will be able to provide a complete profile detailing the oil's condition and, as a result, will recommend replacing or filtering the oil.
4. Review the Mechanical Equipment
A press brake's mechanical components—piston bolts, chain sprockets, and guides—must be checked a minimum of twice a year.Components requiring weekly lubrication are:Ram guiding system,Guide encoders, encoder guiding system,Rack and pinion system,Ball screws,Guides and rails,Gear segment.Maintain the proper clearance between the ram gibs.
5. Examine the Electrical Equipment
Check all connections on terminal strips, relays, and terminal boxes on motors.
Reseat all printed circuit boards and check for physical damage (cracked solder points, burned parts, etc.).
Check all voltages coming from power supplies and transformers.
Check all cables and switches for damage or malfunction.
Check fans for operation.
Check operation of all machine functions and safety features (e-stops, two-hand controls, etc.).
It is critically important to keep the internal panel temperatures within the range specified by the manufacturer. Keep the internal and cooling fans functioning and the filters for the air-conditioning system or heat exchanger clean. Keep the electrical panel doors closed.
6. Inspect the Tooling
To maximize the press brake tooling's life, select the right tooling for the application. Keep tooling clean and free from mill scale, and perform a visual inspection of tooling every time before use. Tooling that is cracked or damaged in any way must be returned to the tooling manufacturer for evaluation, reconditioning, or replacement. Using tooling that is dented or cracked can put both the machine and operator at risk for serious damage.
