利用作者在应力极点轨迹基础上提出的滑移线场应力图解法,本文对圆轴V砧横锻应力进行了图解分析,并与圆轴平砧横锻应力作了比较。分析表明,采用V砧横锻提高了滑移线场内各点的静水压力,减少了锻件内部开裂的危险性。对于V砧横锻时锻件心部出现的难变形区的范围,本文也通过图解分析进行了定量地论证。 Based on the stress field mapping of the slip-line field proposed by the author, this paper gives a graphical analysis of the transverse forging stress of the round-axis V-Anvil, and compares it with the horizontal-forging stress of a round-axis anvil. Analysis shows that the use of V-anvil cross-forging increases the hydrostatic pressure at each point in the slip line field and reduces the risk of internal cracking in forgings. For the cross-forging V-when forging the heart of the Ministry of the difficult deformation of the area, this article also by graphic analysis of a quantitative demonstration.
