现在应用摆动辗压技术的工厂越来越多,工艺范围日趋广泛,所取得的经济效益也越来越大。但是,目前还存在摆辗模具寿命偏低的问题,影响了摆动辗压技术的推广和效果。因此,如何合理的设计和使用模具,使其达到或超过常规锻造所使用的模具寿命,已成为一个重要的课题。我厂200t卧式摆动辗压机的模具使用寿命已达到常规锻压模的水平。现简介如下: 模具工作条件(与常规锻造相比,以下同)是摆动辗压机的模具与锻件接触时间长。以我厂200t摆动辗压机辗压半轴为例,锻件随凹模做水平进给,到辗头接触锻件时为8秒,辗头辗压锻件为6～8秒,锻件与
Now the application of swing rolling more and more factories, a growing range of technology, the economic benefits obtained by more and more. However, there is still the problem that the life of the swinging die is low, affecting the promotion and effect of swinging rolling technology. Therefore, how to reasonably design and use molds to meet or exceed the mold lifetimes used in conventional forging has become an important issue. Our factory 200t horizontal swing rolling mold die life has reached the level of conventional forging die. Now briefings are as follows: Die working conditions (compared with conventional forging, the following is the same) is swinging the rolling mold and forgings long contact time. Take our factory 200t oscillating roller rolling semi-shaft as an example, the forging with the die to do the level of feed to the roller contact forgings when 8 seconds, roller head forging for 6 to 8 seconds forgings
