摘要
本文对长轴类延伸型系列货叉锻件经过试验研究,制定了成形辊锻新工艺;提出新的模具设计方法;解决了小压下大宽展问题;避免了货叉弯曲过程中的拉缩现象。
A new forge method used in the rolling forge of long-axial-extented fork sets of fork-lift is proposed based on experiments. The problem of wide stretch under small press is solved by a new desigen of dies. The shortening during the bending deformation of forks is avoided.
