众所周知,采用闭式模锻比开式模锻节约20％～40％的原材料;减少切边,相应减少飞边所消耗的加热及锻造设备能量;锻模尺寸小且锻件流线不会被切断,提高了零件的完整性。但闭式模锻锻模寿命低,并对下料制坯及坯料定位等要求较高,锻件出模困难,一般只适用于形状简单而对称的锻件。目前,在摩擦压力机上采用较多,而在锤上采用较少。我厂是锻造专业化厂,一些简单的圆盘类锻件已广泛采用闭式模锻生产,而且都是锤上
As we all know, the use of closed die forging than the open die forging saves 20% to 40% of the raw materials; reduce trimming, the corresponding reduction in flash heating and forging equipment consumed energy; forging die small and forgings streamline will not be cut , Improve the integrity of the part. However, the closed die forging die life is low, and the blanking billet and billet positioning and other demanding, forging a die difficult, generally only applicable to shape simple but symmetrical forgings. Currently, more is used on the friction press while less on the hammer. Our factory is forging specialized factory, some simple disc forgings have been widely used in closed die forging production, and are hammer
