鍛造是指把加熱后的金屬材料鍛制成各種形狀的工具、機械零件或毛坯。鍛造過程中要對這些滾燙的金屬坯料進行各種加工，因此加工過程中高溫、、振動和噪聲是避免不了的。所以鍛造過程安全防護很重要。

Forging is a tool, mechanical part, or blank that is forged from a heated metal material to a variety of shapes. In the process of forging, these hot metal billets should be processed, so high temperature, dust, vibration and noise can not be avoided during the process. Therefore, the safety protection of the forging process is very important.

鋁合金鍛件的生產可在多種鍛造設備上進行。鍛錘可用于開式模鍛和閉式模鍛，其生產費用較低，鍛打時需要控制好錘頭的高度、打擊力量和速度，因為在急劇變形過程中鋁合金對應變速率敏感并具有放熱性。機械壓力機和螺旋壓力機都廣泛用于鋁合金閉式模鍛，適宜于生產中等尺寸、大體積和形狀適度的鋁鍛件。Pulloutisoftenusedinforgingrodsandshaftparts。

The production aluminum alloy forgings can be carried out on a variety of forging equipment. Hammer can be used for open die forging and closed die forging, the production cost is low, when the need to  the forging hammer height, strike force and speed, because of the sharp deformation in the process  Alloy strain rate sensitive and exothermic. Mechanical press and screw press are widely used in aluminum alloy closed die forging, which is suitable for the production of medium size, large volume and moderate shape  aluminum forgings.

自由鍛造分手工自由鍛和機器自由鍛。手工自由鍛生產效率低，勞動強度大，僅用于修配或簡單、小型、小批鍛件的生產。

Manual free forging is inefficient and labor intensive. It is only used for the production of repair or simple, small and small forgings.Free forging cists of manual free forging and machine free forging.
