自由锻造分手工自由锻和机器自由锻。手工自由锻生产效率低，劳动强度大，仅用于修配或简单、小型、小批锻件的生产。
Manual free forging is inefficient and labor intensive. It is only used for the production of repair or simple，forging， ***all and ***all ee forging c***ists of manual free forging and machine free forging.
随着电动机的发明，十九世纪末出现了以电为动力的机械压力机和空气锤，并获得迅速发展。第二次***以来，七十五万千牛的模锻水压机、一千五百千焦的对六万千牛的板料冲压压力机、十六万千牛的热模锻压力机等重型锻压机械，forging谁家好，和一些自动冷镦机相继问世，形成了门类齐全的锻造机械体系。
With the invention of motor，forging价格， the mechanical press and air hammer powered by electricity appeared at the end of nineteenth Century， and developed rapidly. Since the Second World War， the forging water press， one thousand and five hundred thousand char， the punching press of Liu Wanqian cattle， the hot forging press of sixteen thousand thousand cattle， and some automatic cold heading machines h***e come out in succession， forming a complete system of forging machinery.
基本工序：自由锻造时，forging生产商，锻件的形状是通过一些基本变形工序将坯料逐步锻成的。自由锻造的基本工序有镦粗、拔长、冲孔、弯曲和切断等。
The basic process is: free forging， the shape of forging is gradually formed by some basic deformation processes. The basic process of free forging is upsetting， drawing， punching， bending and cutting.
