So, it is always formed on the die-forging hammer by the open-dieforging with insert mode.
液压支架中的缸底生产批量不是太大，外形多变，所以它多在锤上用镶块模开式模锻成形。

A distinction may be made between open-dieforging, usually in the form of hammer forging, and closed-die forging.
锤锻中常用的开式模锻与闭式模锻是有区别的。

Based on the analytic results of the numerical simulation, the forming process and the mould structure for the spur-gear open-dieforging were designed properly.
