摘要
大型锻件的基本锻造工序是镦粗和拔长,二者都能改善锻件的内部质量。探讨了扭转镦粗的原理,分析了影响扭转镦粗的各种因素;介绍了型砧拔长工艺,评述了各种不同型砧对拔长效果的影响。
The basic forging procedures of large forgings are upsetting and stretching, which can both improve the internal quality of forgings. The principle of torsion upsetting was discussed. Various factors influencing the twisting and upsetting were analyzed. Swage die stretching technology was introduced. The influences of various swages die stretching on stretching effect were related.
