Maintenance and maintenance of four-corner welding machine

7. 1 Regularly check the fastening joints on the cylinders of various mechanism parts to prevent looseness.

7.2 The working faces of locating plate, profile baffle and upper and lower pressure tongs should be kept clean and free of oil stain, so as not to reduce the welding quality or dirty the profile surface, and other parts should also be kept clean and wiped once per shift.

7.3 The PTFE welding cloth wrapped on the heating plate must be kept intact, clean and flat, otherwise it should be replaced, and the welding cloth should be replaced after power failure. Plastic residue on the welding cloth should be scraped off in time.

7.4 Oil-free lubricated bearings or linear motion ball bearings shall be selected for each sliding mechanism of the welding machine, and the lubrication of oil mist in the air source processor shall meet the above requirements, otherwise the functional reliability of the solenoid valve will be affected.

7.5 The shaft and bearing must be cleaned frequently and lightly lubricated. In general, linear bearing does not need any lubrication, because the amount of grease in the bearing can meet the use requirements.

7.6 The filter element and water storage cup of water separation filter in air source processor should be cleaned and drained regularly.

7.7 For the power supply system at the welding site, check the relationship between the phase of the four-corner welder and the center line every time it is overhauled.

7.8 The electric control cabinet should be kept clean. Non-professionals are prohibited from opening the two-wire interface cover of the programmable controller. It is forbidden to dismantle the internal program of the programmable controller to save the battery without reason.

7.9 The programmable controller keeps the battery discharge life for more than 5 years. When the battery voltage drops, the battery, Y and LED indicators in the upper right corner of the PLC panel will light up. Regardless of the working conditions, it is recommended to replace the battery every five years. Before replacing the battery, cut off the power supply, and the battery replacement must be completed within 30 seconds.

7. 10 The service life of the nose counterweight wire rope is one year, and it should be checked once per shift. If you find any damage such as rotation and fuzzing, please replace it in time to avoid accidents.

7. 1 1 For welded profiles with a thickness less than 36MM, you can contact our company to customize a special pad.
