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.

鍛造工藝過程一般由以下工序組成，即選取鋼坯下料、加熱、成形、鍛后冷卻。鍛造的工藝方法有自由鍛、模鍛和胎膜鍛。生產時，按鍛件質量的大小，生產批量的多少選擇不同的鍛造方法。

The forging process is generally  of the following processes, namely, the selection of high quality billets, heating, forming and cooling after forging. The forging process includes free forging, die forging and fetal membrane forging. When manufacturing, according to the size of forgings and the number of production batches, different forging methods are chosen.

自由鍛造是靠人工操作來控制鍛件的形狀和尺寸的，所以鍛件精度低，加工余量大，勞動強度大，生產率也不高，因此它主要應用于單件、小批量生產。

Free forging is by manual operation to the shape and size of the forgings, so the precision of the forgings is low, the processing allowance is large, the labor intensity is big, and the productivity is not high. Therefore, it is mainly used in single piece and small batch production.

拔長

也稱延伸，它是使坯料橫斷面積減小、長度增加的鍛造工序。拔長常用于鍛造桿、軸類零件。

自由鍛造的基本工序包括鐓粗、拔長、沖孔、彎曲、扭轉、錯移、切割及鍛接等。

Pulling length

Also known as elongation, it is a forging process to reduce the cross-sectional area of the billet and increase the length. Pullout is often used in forging rods and shaft parts.

The basic processes of free forging include upsetting, drawing, punching, bending, torsion, offset, cutting and forging.
