Hydraulic bending roll maintenance procedures
Hydraulic bending roll maintenance procedures:
1, according to the machine lubrication schematic, wire drawing machine according to the requirements of the oil cup lubrication and artificial lubrication points for refueling.
2, according to the parameters of the hydraulic bending roll trigger coil plate, the plate thickness of 20 mm, maximum length is 2500 mm, plate material yield limit is less than 250 mpa.
3, after turning on the power supply, wire drawing machine of roller on the positive and negative directions and roller lifting movement, check the movement has all the normal card death phenomenon.
4, in strict accordance with the hydraulic bending roll roll plate processing procedures and operation method, on the roll to the limit position, pays great attention to the safe operation of equipment.
5, after the main drive down, before being on the rise and fall of roller, wire drawing machine roll bearing of dumping the reset and the upper roller camber.
6, in the process of operation, if found to have abnormal phenomena, such as the irregular noise, shock, it is necessary to stop the machine immediately to check.
In 7, the operation personnel to coordinate each other, follow rolled plate, head of the command, no password, forbidden to start the machine.
8, for the hydraulic bending roll roll plate operation should be pay attention to the hand was pinned under involved with steel plate.
9, with the lifting of driving plates or drum, be careful not to collision and wire drawing machine.
After the hydraulic bending roll coil plate, finish do work is expected to do site, and make the equipment maintenance work, turn off the power supply in a timely manner.
