定期對設(shè)備進(jìn)行保養(yǎng)，所有的操作者工作之前必須帶好防護(hù)用具。在進(jìn)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.

在現(xiàn)代工業(yè)生產(chǎn)中，機器自由鍛已成為鍛造生產(chǎn)的主要方法，在重型機械制造中，它具有特別重要的作用。而產(chǎn)生的鍛件形狀和尺寸主要由操作工的技術(shù)水平?jīng)Q定。

In modern industrial production, machine free forging has become the main method of forging production, and it plays a particularly important in heavy machinery manufacturing. The shape and size of the forgings are mainly determined by the technical level of the operator.

鐓粗主要有以下形式：

完全鐓粗。完全鐓粗是將坯料豎直放在砧面上， 在上砧的錘擊下， 使坯料產(chǎn)生高度減小，橫截面積增大的塑性變形。

Upsetting mainly includes the following forms:

Full upsetting. Complete upsetting is to place the blank vertically on the anvil surface, hammering on the anvil, so that the height of the blank decreases, the cross-sectional area increases plastic deformation.
