一种新型时效方式在压力机机身上的应用

摘要

分析了传统热时效去除压力机机身焊接残余应力的缺陷,介绍了频谱谐波时效的技术特点与优点,用试验和数据证明频谱谐波时效的效果,验证了频谱谐波在去除压力机焊接机身残余应力的可行性.%Analysis the defects of the traditional methods TSR of the eliminate the residual stress of press frame,introduces the technical characteristics and advantages of harmonic frequency spectrum VSR,with testing and data proof harmonic frequency spectrum VSR effect,further validation harmonic frequency spectrum VSR in removing welding press frame residual stress of feasibility.
