补充资料：锻造
| 锻造 forging 利用锻压机械对金属坯料施加压力，使其产生塑性变形以获得具有一定机械性能、一定形状和尺寸锻件的加工方法。锻压的两大组成部分之一。通过锻造能消除金属的铸态疏松，焊合孔洞，锻件的机械性能一般优于同样材料的铸件。机械中负载高、工作条件严峻的重要零件，除形状较简单的可用轧制的板材、型材或焊接件外，多采用锻件。锻造按成形方法可分为：①开式锻造（自由锻）。利用冲击力或压力使金属在上下两个抵铁（砧块）间产生变形以获得所需锻件，主要有手工锻造和机械锻造两种。②闭模式锻造。金属坯料在具有一定形状的锻模膛内受压变形而获得锻件，可分为模锻、冷镦、旋转锻、挤压等。按变形温度锻造又可分为热锻（加工温度高于坯料金属的再结晶温度）、温锻（低于再结晶温度）和冷锻（常温）。锻造用料主要是各种成分的碳素钢和合金钢，其次是铝、镁、钛、铜等及其合金。材料的原始状态有棒料、铸锭、金属粉末和液态金属等。金属在变形前的横断面积与变形后的模断面积之比称为锻造比。正确地选择锻造比对提高产品质量、降低成本有很大关系。 |
