鍛造是指把加熱后的金屬材料鍛制成各種形狀的工具、機械零件或毛坯。鍛造過程中要對這些滾燙的金屬坯料進行各種加工，因此加工過程中高溫、、振動和噪聲是避免不了的。所以鍛造過程安全防護很重要。

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.

定期對設(shè)備進行保養(yǎng)，所有的操作者工作之前必須帶好防護用具。在進行鍛造作業(yè)時，幾個操作者之間要集中精力，互相配合，躲開危險方向，選擇相對安全的位置。

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.

拔長 拔長是使坯料的長度增加，截面減小的鍛造工序，通常用來生產(chǎn)軸類件毛坯，如車床主軸、連桿等。

沖孔 用沖子在坯料上沖出通孔或不通孔的鍛造工序。彎曲 使坯料彎曲成一定角度或形狀的鍛造工序。

Drawing and drawing is a forging process that increases the length of the billet and reduces the section. It is usually used to produce shaft parts, such as spindle and connecting rod.

Forging punch punching out through holes or blind holes in the blank. The forging process of bending the billet into a certain angle or shape.
