蒸汽锤是一个活塞—连杆—滑块往复直线运动机构。汽锤落下部分包括:活塞、锤杆、锤头、上砧块和斜楔组成。汽锤正常作业时,落下部分每分钟往复运动80次,一个昼夜连续工作运动近10万次之多,使锤在工作时各个零件受到极大的循环冲击载荷,特别是直接进行锤击的落下部分,受力更大,更直接。锤杆容易折断,锤头燕尾破裂严重。多年来虽然对汽锤的一些易损零件(例如锤杆、锤头、上、下砧等)在材质、热处理及生产工艺上作了一系列的改进,收到了一定效果。但锤头燕尾破裂严重,寿命低,配
Steam hammer is a piston - connecting rod - slider reciprocating linear motion mechanism. Hammer falling parts include: piston, hammer, hammer, anvil and wedge on the composition. Hammer normal operation, falling part of the reciprocating movement 80 minutes per minute, a continuous work of day and night movement of nearly 100,000 times, so that the hammer at work all parts subjected to a great cycle of impact load, especially direct hammer down Part, greater force, more direct. Hammer easily broken, hammer swallowtail rupture serious. Over the years, although some of the consumable parts (such as hammer rod, hammerhead, upper and lower anvil, etc.) of the steam hammer have made a series of improvements in the material, heat treatment and production process, and received some results. But the hammer swallowtail rupture serious, low life, with
