热模锻是大批和大量生产锻件效率最高,和最便宜的一种生产过程,模锻的主要优点,是能够得到复杂形状的锻件,和具有较高的性能。热模锻广泛的运用在机器制造。从机械零件制造成本来分析,零件经模锻后迸行机械加工较直接迸行机械加工的,价格约低2～2.5倍。很多的模锻件经过局部机械加工后可以直接迸行装配。因此模锻工艺和冲压工艺同样都是一种先进的工艺。 Hot forging is one of the most efficient and economical processes for mass production and mass production of forgings. The main advantage of forging is the ability to obtain forgings of complex shapes and with high performance. Hot forging is widely used in machine building. From the analysis of the manufacturing cost of mechanical parts, machined parts machined more directly after machining, the price is about 2 to 2.5 times lower. A lot of forging pieces after partial machining can be assembled directly. Therefore, forging process and stamping process are also an advanced technology.
