蒸-空模锻锤锤杆是受多次冲击的典型另件,常常因为受冲击疲劳而折断。因其造价昂贵,使用寿命又较短,从而使锻锤的维修费用显著增加。为此,国内外的有关部门都对提高锤杆的使用寿命给予重视。多年来我厂也在这方面作了一些工作。实践证明,虽然影响锤杆寿命的因素较多,但抓住了主要矛盾,也可以取得良好的效果。1975年一机部在洛阳组织召开现场会,我厂介绍了在提高锤杆寿命方面的一些做法,下面就其受力条件,断裂原因、加工方法和提高寿命的措
Steamed - empty forging hammer hammer rod is subject to repeated impact of the typical pieces, often because of impact fatigue and broken. Because of its high cost, shorter life, so that forging hammer maintenance costs increased significantly. To this end, the relevant departments at home and abroad to improve the service life of the hammer to pay attention. Over the years I also made some work in this area. Practice has proved that although many factors affect the life of the hammer rod, but seize the main contradiction, but also can achieve good results. In 1975, a machine department organized a live meeting in Luoyang. Our factory introduced some ways to improve the service life of the hammer rod. The following is a brief introduction of its stress conditions, causes of fracture, processing methods and life expectancy
