蒸汽錘一般只适合自由鍛造,而模鍛必須用模鍛錘。但是我国工厂的鍛造設备多数还是蒸汽錘,所以普遍推行模鍛法还有一些困难。我厂出国实习同志回厂后根据苏联工厂的經驗,在蒸汽錘上进行模鍛有了很好的效果。这种經驗虽然不十分完整,但很有介紹給大家参考的价值。模鍛装置模鍛装置是利用蒸汽錘旧上下砧改装成的,如图1所示。1是蒸汽錘上砧,用楔固定在錘头上。2、3是鉄板,根据工作时的强度可以用2块或4块組成,焊接在上砧和上模4上。5是导正銷,用来避免上下模錯牙。6是鍛件。
Steam hammer is generally only suitable for free forging, and forging must be forged hammer. However, most of the forging equipment in our country is still steam hammer, so there are some difficulties in the universal die-forging method. According to the experience of the Soviet factory, the comrade in our factory went abroad to work in die forging on the steam hammer with good results. Although this experience is not very complete, but it is introduced to your reference value. Die forging device forging device is the use of steam hammer on the anvil converted into the old, as shown in Figure 1. 1 is the steam hammer on the anvil, wedge fixed on the hammerhead. 2 and 3 are slats, which can be composed of two or four pieces according to the strength of the work and welded on the upper anvil and the upper die 4. 5 is the guide pin, used to avoid the upper and lower die wrong teeth. 6 is forgings.
