自由锻和模锻的区别
Difference between free forging and die forging
自由锻是将加热好的金属坯料放在锻造设备的上，下砥铁之间，施加冲击力或压力，直接使坯料产生塑性变形，从而获得所需锻件的一种加工方法。自由锻由于锻件形状简单，操作灵活,适用于单件，小批量及重型锻件的生产。
Free forging is a processing method that places the heated metal blank between the upper and lower grinding iron of the forging equipment and applies impact force or pressure to directly produce plastic deformation of the blank, so as to obtain the required forging. Due to the simple shape and flexible operation of forgings, free forging is suitable for the production of single piece, small batch and heavy forgings.
自由锻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，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。
Free forging is divided into manual free forging and machine free forging Manual free forging has low production efficiency and high labor intensity. It is only used for repair or production of simple, small and small batches of forgings. In modern industrial production, machine free forging has become the main method of forging production. It plays a particularly important role in heavy machinery manufacturing.
