在现代工业生产中，机器自由锻已成为锻造生产的主要方法，在重型机械制造中，它具有特别重要的作用。而产生的锻件形状和尺寸主要由操作工的技术水平决定。
In modern industrial production， machine free forging has become the main method of forging production， and it plays a particularly important in he**y machinery manufacturing. The shape and size of the forgings are mainly determined by the technical level of the operator.
镦粗 镦粗是对原坯料沿轴向锻打，圣霖国际锻造，使其高度减低、横截面增大的操作过程。这种工序常用于锻造齿轮坯和其他圆盘形类锻件。镦粗分为全部镦粗和局部锻粗两种。
Upsetting and upsetting is the process of forging the original billet along the axis， reducing its height and increasing its cross section. This process is usually used to forge gear blanks and other disc shaped forgings. The upsetting is divided into two kinds of upsetting and local forgings.
自由锻生产率低，加工余量大，圣霖国际锻造厂，但工具简单，通用性大，圣霖国际锻造生产，故被广泛用于锻造形状较简单的单件、小批生产的锻件。自由锻设备有空气锤、蒸汽-空气锤和水压机等，分别适合小、中和大型锻件的生产。
Free forging has many advantages such as low productivity， large machining allowance， but simple tool and versatility. So it is widely used for forging single piece and **all batch forgings with simpler shape. The free forging equipments include air hammer， steam air hammer and hydraulic press， etc.， which are suitable for the production of **all and medium he**y forgings， respectively.
