本文提出了一端或两端具有粗大头部的长轴线类锻件的镦挤技术,论述在压力机的一次行程中可以镦锻出长径比大于3的坯料。阐述了计算工艺参数的方法。并以双头梅花板手制坯工艺的改进为例,介绍了镦挤制坯技术在生产中的应用。
In this paper, the upsetting technology of long axis forgings with thick heads at one end or both ends is proposed. It is discussed that a blank with an aspect ratio greater than 3 can be upset forged in one stroke of the press. The method of calculating process parameters is expounded. Taking the improvement of handmade billets of double plum blossom plate as an example, the application of upsetting and extruding billets technology in production was introduced.
