自由鍛。指用簡(jiǎn)單的通用性工具，或在鍛造設(shè)備的上、下砧鐵之間直接對(duì)坯料施加外力,使坯料產(chǎn)生變形而獲得所需的幾何形狀及內(nèi)部質(zhì)量的鍛件的加工方法。 采用自由鍛方法生產(chǎn)的鍛件稱為 自由鍛件。

Free forging. It refers to the processing method of forgings directly using the external force between the upper and the lower anvil of forging equipment, so as to get the required geometry and internal quality by applying external force directly to the billet. Forgings produced by free forging are called free forgings.

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.

自由鍛造是利用沖擊力或壓力使金屬在上下砧面間各個(gè)方向自由變形，不受任何限制而獲得所需形狀及尺寸和一定機(jī)械性能的鍛件的一種加工方法，簡(jiǎn)稱自由鍛。

Free forging is a processing method of forging parts, which can make metal in all directi of the anvil between the upper and lower anvil, and obtain the required shape and size and certain mechanical properties by the impact force or pressure, and the free forging is called free forging.

自由鍛造所用工具和設(shè)備簡(jiǎn)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(jiǎn)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.
