鍛造是一種利用鍛壓機(jī)械對金屬坯料施加壓力，使其產(chǎn)生塑性變形以獲得具有一定機(jī)械性能、一定形狀和尺寸鍛件的加工方法，鍛壓（鍛造與沖壓）的兩大組成部分之一。

Forging is a kind of forging process that uses pressure forming machinery to exert pressure on metal billet and make it produce plastic deformation to obtain certain processing methods of forging, which has certain mechanical properties, shape and size, and is one of the two components of forging, forging and stamping.

自由鍛都是以生產(chǎn)批量不大的鍛件為主，采用鍛錘、液壓機(jī)等鍛造設(shè)備對坯料進(jìn)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(zhuǎn)、錯(cuò)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.

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(dòng)強(qiáng)度大，生產(chǎn)率也不高，因此它主要應(yīng)用于單件、小批量生產(chǎn)。

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.
