简介能减少曲辅扭转角度的“错压法”。实践证明,这种新方法较传统的“错拐法”具有一系列优点,特别能获得高锻造比,保证锻件质量。本文以三拐曲轴为例,对于六拐或七拐曲轴锻件锻造也有参考价值。 Introduction The “wrong pressure method” that can reduce the angle of twists and turns. Practice has proved that this new method has a series of advantages over the traditional “wrong turn method”, and in particular, can obtain a high forging ratio and ensure forging quality. In this paper, the three-crank crankshaft, for example, for six or seven crank forging crankshaft forging reference value.
