鍛造設(shè)備是指在鍛造加工中用于成形和分離的機(jī)械設(shè)備。鍛造設(shè)備包括成形用的鍛錘、機(jī)械壓力機(jī)、液壓機(jī)、螺旋壓力機(jī)和平鍛機(jī),以及鍛造操作機(jī)、開卷機(jī)、矯正機(jī)、剪切機(jī)、等輔助設(shè)備。

Forging equipment is the mechanical equipment for forming and separating in forging. Forging equipment includes forging hammer, mechanical press, hydraulic press, screw press, forging machine, forging machine, coiler, straightening machine, shearing machine, and other auxiliary equipment.


隨著電動(dòng)機(jī)的發(fā)明,十九世紀(jì)末出現(xiàn)了以電為動(dòng)力的機(jī)械壓力機(jī)和空氣錘,并獲得迅速發(fā)展。自由鍛的基本工序包括鐓粗、拔長、沖孔、切割、彎曲、扭轉(zhuǎn)、錯(cuò)移及鍛接等。第二次以來,七十五萬千牛的模鍛水壓機(jī)、一千五百千焦的對六萬千牛的板料沖壓壓力機(jī)、十六萬千牛的熱模鍛壓力機(jī)等重型鍛壓機(jī)械,和一些自動(dòng)冷鐓機(jī)相繼問世,形成了門類齊全的鍛造機(jī)械體系。

With the invention of motor, the mechanical press and air hammer powered by electricity appeared at the end of nineteenth Century, and developed rapidly. Since the Second World War, the forging water press, one thousand and five hundred thousand char, the punching press of Liu Wanqian cattle, the hot forging press of sixteen thousand thousand cattle, and some automatic cold heading machines have come out in succession, forming a complete system of forging machinery.


在現(xiàn)代工業(yè)生產(chǎn)中,機(jī)器自由鍛已成為鍛造生產(chǎn)的主要方法,在重型機(jī)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.
