上海第八机床厂最近试制成功一种专门加工较大型锻造模具的机床。这种机床叫电脉冲成型穿孔机床,它的功率是20千瓦,可以加工一吨重的锻模。这种机床的特点是可以加工硬度较高的模具,加工后不会变形,而且生产率高,对汽车、拖拉机工厂以及有大量锻件的工厂特别适用。电脉冲成型加工是机械工业的一种新的加工技术。过去模具制造,很多工厂都是由钳工用手工加工,有些工厂用仿型铣床加工,但效率较低。而D5570电脉冲成型穿孔机床,生产效率高。如加工一副形状复杂的摇臂锻模,只化了二个半小时,但原来用仿型铣加工要25小时;又如加工一副推土机链条片锻模只化了12小时,但原来用铣削方法加工需104小时。因此这种机床加工锻模的生产率此其他制造方法大大提高。
Shanghai Eighth Machine Tool Factory recently successfully trial a larger machine forging larger die. This machine is called electric pulse forming machine, it has a power of 20 kilowatts, can process a ton of forging die. This type of machine is characterized by its ability to machine molds with high hardness without deformation after processing and with high productivity and is particularly suitable for vehicles, tractor factories and factories with large numbers of forgings. Electric pulse forming is a new processing technology in mechanical industry. Mold manufacturing in the past, many factories are hand-made by fitters, and some factories use profiling milling machines, but less efficient. The D5570 electric pulse forming punching machine, high production efficiency. Such as the processing of a complex shape rocker forging die, only for two and a half hours, but the original use of imitation milling to 25 hours; Another example is the processing of a bulldozer chain forging die only 12 hours, but the original use Milling method for 104 hours. Therefore, the productivity of this machine tool forging die greatly increased this other manufacturing methods.
