锻造是指把加热后的金属材料锻制成各种形状的工具、机械零件或毛坯。锻造过程中要对这些滚烫的金属坯料进行各种加工，因此加工过程中高温、、振动和噪声是避免不了的。所以锻造过程安全防护很重要。

Forging is a tool, mechanical part, or blank that is forged from a heated metal material to a variety of shapes. In the process of forging, these hot metal billets should be processed, so high temperature, dust, vibration and noise can not be avoided during the process. Therefore, the safety protection of the forging process is very important.

定期对设备进行保养，所有的操作者工作之前必须带好防护用具。在进行锻造作业时，几个操作者之间要集中精力，互相配合，躲开危险方向，选择相对安全的位置。

Maintenance of equipment on a regular basis, and all operators must take protective equipment before working. In the process of forging, several operators should their energy, cooperate with each other, avoid the dangerous direction, and choose a relatively safe.

不知道听到工艺两个字的时候我们更多的想到的是什么?我想很多人对工艺的追求大多体现在对一些艺术品上面。其实不仅仅是艺术品对工艺的要求非常高。在我们的机械领域对工艺也是精益求精的，因为只有高超的工艺才能制造出更的产品，就比如说大口径法兰对它的工艺要求也是很高的。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。

I don't know what we think about more when we hear the two  of the craft?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。 I think a lot of people's pursuit of the craft is mostly on some of the works of art. In fact, not only is the art of art demanding very high technology. In our field of machinery, we also strive for improvement in technology, because only superb technology can make more perfect products, for example, large diameter flanges require high technological requirements for them.

自由锻造的设备分为锻锤和液压机两大类。生产中使用的锻锤有空气锤和蒸汽-空气锤，有些厂还使用结构简单，投资少的弹簧锤、夹板锤、杠杆锤和钢丝锤等。

The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The forging hammers used in production are air hammer and steam-air hammer. Some factories also use spring hammer, splint hammer, lever hammer and steel wire hammer with simple structure and low investment.
