自由锻都是以生产批量不大的锻件为主，采用锻锤、液压机等锻造设备对坯料进行成形加工，获得合格锻件。 自由锻的基本工序包括镦粗、拔长、冲孔、切割、弯曲、扭转、错移及锻接等。自由锻采取的都是热锻方式。

Free forging is in the production of *all quantities of forgings， the forging，forging生产厂家， hydraulic press forging equipment is carried out on the blank forming process， obtain qualified forgings. The basic process of free forging including upsetting，鞍山forging， stretching， punching， cutting， bending， torsion， displacement and welding etc.. The free forging is all hot forging.

在现代工业生产中，forging价格，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.

铝合金锻件的生产可在多种锻造设备上进行。锻锤可用于开式模锻和闭式模锻，其生产费用较低，锻打时需要控制好锤头的高度、打击力量和速度，因为在急剧变形过程中铝合金对应变速率敏感并具有放热性。机械压力机和螺旋压力机都广泛用于铝合金闭式模锻，适宜于生产中等尺寸、大体积和形状适度的铝锻件。

The production aluminum alloy forgings can be carried out on a variety of forging equipment. Hammer can be used for open die forging and closed die forging， the production cost is low， when the need to the forging hammer height， strike force and speed，forging哪家好， because of the sharp deformation in the process Alloy strain rate sensitive and exothermic. Mechanical press and screw press are widely used in aluminum alloy closed die forging， which is suitable for the production of medium size， large volume and moderate shape aluminum forgings.
