Description
TECHNICAL FIELD
[0001] The utility model relates to guide and guide wheel axle dismantling technical field, concretely relates to a kind of bar pre-precision rolling guide and guide wheel axle dismantling auxiliary device. BACKGROUND
[0002] In steel rolling production, guide and guard system is the core device to ensure that bar material enters the roll accurately, and guide wheel axle is the key component of guide and guard, which needs to be regularly disassembled, maintained or replaced due to long-term high temperature, high pressure and friction. However, the disassembly process of the traditional guide wheel axle has the problems of difficult operation, low efficiency, the guide wheel axle and the guide frame are tightly fixed by pins, the internal space is narrow, and the worker needs to bend down to observe the pin position and repeatedly hit with an ordinary hammer. This process relies on experience, and any slight mistake will cause the pin to be deformed or damaged. The disassembly time of a single disassembly is about 10 minutes, and skilled workers are needed to operate, which affects the production rhythm. The tool is not special, and the easy-to-damage component is used with the traditional general knocking tool (such as ordinary hammer and crowbar), which does not match the size and space of the guide wheel axle pin. When knocking, it is easy to slip, not only damaging the pin, but also possibly scratching the guide frame, increasing the cost of spare parts replacement. According to statistics, the scrap rate of the pin caused by improper disassembly is as high as 30%, which significantly increases the maintenance cost. There are safety hazards and high labor intensity. The worker needs to maintain the bent-down posture for a long time, and there is a risk of being hit by the rebound of the hammer. In addition, it is easy to cause waist strain.
[0003] Therefore, it is urgent to design a bar pre-precision rolling guide and guide wheel axle disassembly auxiliary device to solve the problems of existing technology, such as difficult operation, low efficiency, easy damage, high cost and high labor intensity of workers.
