自由鍛的基本工序主要有鐓粗、拔長、沖孔、切割、彎曲、扭轉(zhuǎn)、錯(cuò)移及鍛接等。模鍛又分為開式模鍛和閉式模鍛．金屬坯料在具有一定形狀的鍛模膛內(nèi)受壓變形而獲得鍛件，模鍛一般用于生產(chǎn)重量不大、批量較大的零件。

The basic process of free forging are upsetting, stretching, punching, cutting, bending, torsion, displacement and welding etc.. Die forging is also divided into open die forging and closed die forging. metal billets are pressed and deformed to form forgings in the forging die chamber with a certain shape, and die forging is generally used for producing parts with small weight and large batches.

選擇好的鍛件產(chǎn)品跟鍛造工藝或者鍛造廠家肯定是有關(guān)系的，現(xiàn)在有越來越多的鍛件廠走向市場，對(duì)此，用戶挑選鍛件產(chǎn)品的難度就增加了。如果對(duì)鍛件缺乏專業(yè)的認(rèn)識(shí)，那么，在選擇的時(shí)候就會(huì)多很多顧忌。

The selection of good forging products is closely related to forging process or forging factories. Now more and more forgings factories are going to the market. Therefore, users' difficulty in selecting forgings is increasing. If the forgings are lack of professional knowledge, there will be a lot of scruples when choosing.

鍛造設(shè)備種類很多，按照工作部分運(yùn)行方式不同，鍛造設(shè)備可分為直線往復(fù)運(yùn)動(dòng)和相對(duì)旋轉(zhuǎn)運(yùn)動(dòng)兩大類。直線往復(fù)鍛造設(shè)備1、動(dòng)載撞擊的鍛造設(shè)備2、動(dòng)靜載聯(lián)合的鍛造設(shè)備3，能沖擊的鍛造設(shè)備。

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

自由鍛造所用工具和設(shè)備簡單，通用性好，成本低。 同鑄造毛坯相比，自由鍛消除了縮孔、 縮松、氣孔等缺陷，使毛坯具有更高的力學(xué)性能。鍛件形狀簡單，操作靈活。

Free forging tools and equipment are simple, versatility and low cost. Compared with the casting blank, the free forging eliminates the defects such as shrinkage porosity, porosity, porosity and so on, so that the blank has higher mechanical properties. The shape of the forgings is simple and the operation is flexible.
