自由鍛都是以生產批量不大的鍛件為主，采用鍛錘、液壓機等鍛造設備對坯料進行成形加工，獲得合格鍛件。 自由鍛的基本工序包括鐓粗、拔長、沖孔、切割、彎曲、扭轉、錯移及鍛接等。自由鍛采取的都是熱鍛方式。

Free forging is in the production of small quantities of forgings, the forging, hydraulic press forging equipment is carried out on the blank forming process, obtain qualified forgings. The basic process of free forging including upsetting, stretching, punching, cutting, bending, torsion, displacement and welding etc.. The free forging is all hot forging.

鍛造生產加熱設備和鍛壓設備不可少，這些設備釋放大量熱能，需要我們在通風凈化環境中進行。鍛造工具種類繁多，也是密集型作業，要求每個技術人員都不能馬虎，堅守自己的崗位，嘈雜的環境需要冷靜的技師，不能隨意操作。

Forged production of heating equipment and forging equipment can not be less, these release a large amount of heat energy, we need to carry out in the ventilation and purification environment. There are various kinds of forging tools, which are also intensive operati. Every technician is not allowed to be careless and stick to their. The noisy environment needs a cool technician and can not be arbitrarily operated.

在芯棒上拔長。鍛造時，先芯棒插入沖好孔的坯料中，然后當作實心坯料進行拔長。拔長時，一般不是一次拔成，先將坯料拔成六角形，鍛到所需長度后，再倒角滾圓，取出芯棒。為便于取出芯棒，芯棒 的工作部分應有1：100 左右的斜度。

Pull on the mandrel. When forging, insert the mandrel into the billet of the hole and then pull it out as a solid billet. When drawing, it is not usually drawn at one time. First, the blank is drawn into a hexagonal shape, forged to the required length, then chamfered and rounded, and the mandrel is removed. To facilitate the removal of the mandrel, the working part of the mandrel should have a slope of about 1:100.

鐓粗主要有以下形式：

完全鐓粗。完全鐓粗是將坯料豎直放在砧面上， 在上砧的錘擊下， 使坯料產生高度減小，橫截面積增大的塑性變形。

Upsetting mainly includes the following forms:

Full upsetting. Complete upsetting is to place the blank vertically on the anvil surface, hammering on the anvil, so that the height of the blank decreases, the cross-sectional area increases plastic deformation.
