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。在锻造时，金属的脆性杂质被打碎，顺着金属主要伸长方向呈碎粒状或链状分布。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, 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.

锻造设备种类很多，按照工作部分运行方式不同，锻造设备可分为直线往复运动和相对旋转运动两大类。直线往复锻造设备1、动载撞击的锻造设备2、动静载联合的锻造设备3，能冲击的锻造设备。

There are many kinds of forging equipment. According to the different operation modes of the working part, the forging equipment can be divided into two categories: straight reciprocating motion and relative rotation motion.

Linear reciprocating forging equipment

1, forging equipment with dynamic load impact

2, forging equipment combined with static and static load

3, high efficiency impacting forging equipment

自由锻造是利用冲击力或压力使金属在上下砧面间各个方向自由变形，不受任何限制而获得所需形状及尺寸和一定机械性能的锻件的一种加工方法，简称自由锻。

Free forging is a processing method of forging parts, which can make metal in all directi of the anvil between the upper and lower anvil, and obtain the required shape and size and certain mechanical properties by the impact force or pressure, and the free forging is called free forging.

自由锻造是靠人工操作来控制锻件的形状和尺寸的，所以锻件精度低，加工余量大，劳动强度大，生产率也不高，因此它主要应用于单件、小批量生产。

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.
