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.

不知道聽到工藝兩個(gè)字的時(shí)候我們更多的想到的是什么?我想很多人對(duì)工藝的追求大多體現(xiàn)在對(duì)一些藝術(shù)品上面。自由鍛造是靠人工操作來控制鍛件的形狀和尺寸的，所以鍛件精度低，加工余量大，勞動(dòng)強(qiáng)度大，生產(chǎn)率也不高，因此它主要應(yīng)用于單件、小批量生產(chǎn)。其實(shí)不僅僅是藝術(shù)品對(duì)工藝的要求非常高。在我們的機(jī)械領(lǐng)域?qū)に囈彩蔷媲缶?，因?yàn)橹挥懈叱墓に嚥拍苤圃斐龈漠a(chǎn)品，就比如說大口徑法蘭對(duì)它的工藝要求也是很高的。

I don't know what we think about more when we hear the two  of the craft?碾環(huán)是指通過專用設(shè)備碾環(huán)機(jī)生產(chǎn)不同直徑的環(huán)形零件，主要用來生產(chǎn)汽車輪轂、火車車輪等輪形零件。 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.

鍛造設(shè)備主要用于金屬成形，所以又稱為金屬成形機(jī)床。鍛造設(shè)備是通過對(duì)金屬施加壓力使之成形的，力大是其基本特點(diǎn)，故多為重型設(shè)備，設(shè)備上多設(shè)有安全防護(hù)裝置，以保障設(shè)備和人身安全。

Forging equipment is mainly used for metal forming, so it is also called metal forming machine tool. Forging equipment is formed by exerting pressure on metal, and its basic characteristics are large force. Therefore, most of the equipment are heavy equipment, and many safety protection devices are set up on the equipment to ensure the safety of the equipment and the body.
