近几十年来,由于模锻件的大型化,对切边压力机的吨位要求也越来越大。鉴于制造大型机械压力机的困难,国内外都设计制造了切边液压机。国内自六十年代以来,定型生产了多台1000吨、2000吨、3200吨用于同模锻锤或无砧座锤配套的热切边液压机。但这些设备在使用中尚存在一些问题。对此,我们做了一些工作,现整理出来,供参考。 In recent decades, due to the forging of large-scale, trimming presses on the tonnage requirements are also growing. In view of the difficulty of manufacturing large mechanical presses, both at home and abroad have designed and manufactured trimming hydraulic machine. Since the 1960s, China has produced more than 1,000 tons, 2,000 tons and 3,200 tons of eager edge hydraulic presses for die forging hammers or anvilless hammers. However, there are still some problems in the use of these devices. In this regard, we have done some work, now sorted out for reference.
