The second shift of the fitter is responsible for the inspection and maintenance of the 1500mm broadband production line heating furnace. Because the high temperature environment where the roller table is located can easily cause bearing wear, it is very difficult to remove the bearing when replacing the roller table. Therefore, each time the maintenance team has to draw a lot of energy to organize the bearing disassembly, which wastes the inspection time and increases everyone's Labor intensity. These were seen by the careful squad leader Cui Xinjun, who was determined to invent a time- and labor-saving disassembly tool to improve efficiency and reduce the labor intensity of everyone.
Cui Xinjun found that when everyone used the ordinary jack hydraulic pick-up to disassemble, if the hand is too strong, it will be easily deformed. Therefore, according to the shape of the roller bearing housing, he first welds a square box to hold the bearing seat, and after stratification, the force points of the jack are evenly dispersed in the square box, even if the jack bears a large The centripetal force, the force of the hand, will not be deformed. Cui Xinjun also welded an adjustable U-shaped bracket at the bottom of the pickpocket to avoid the inconvenience caused by the jacking of the jack.
After the completion of the special pickpocket, Cui Xinjun conducted several disassembly tests. It took three people to use six hours to disassemble a set of roller bearings. Now it can be easily completed by two people in less than half an hour, which not only greatly reduces the labor intensity, but also improves the disassembly efficiency by more than 12 times. After estimation by the technical department, the gas and labor costs for heating acetylene alone are reduced by more than 14,000 yuan per year.
Laigang staff self-made bearing removal tool
A few days ago, Cui Xinjun, the second class clerk of the machine repair workshop of Shandong Laigang Group Co., Ltd., invented the special disassembly tool, which saved time, effort and money to realize the demolition of the roller bearing equipment.
