锻造,不但材料利用率高,而且产品质量和生产率也优越,它起着人们所说的“廉价加工优质产品”的作用。但由于锻造的力量大,因而机器造价和模具费用贵,再加上为消除噪音和振动的措施费用,从而使成本变高,所以一般只限于大量生产使用。摆动辗压法是用较小的力对毛坯局部依次重复加压而达到整体成形的特殊锻造技术。这种方法能适应多品种、小批量生产,而且公害低,故为人们所重视。最近,其锻造范围又扩大到大尺寸的锻件和高强度材料。除了可以增加因辗压力小所得到的经济效果外,还可以节
Forging, not only high material utilization, but also superior product quality and productivity, it plays what people call the “low-cost processing of quality products” role. However, due to the forging force, so the cost of the machine and the mold expensive, coupled with the elimination of noise and vibration measures costs, so that the cost becomes high, so generally limited to mass production. Swing rolling method is to use a smaller force on the blank in turn followed by partial pressure to achieve the overall shape of the special forging technology. This method can adapt to more varieties, small batch production, and low pollution, so people pay attention. Recently, its forging range has been extended to large-size forgings and high-strength materials. In addition to increase the economic effect obtained by the small rolling force, but also can be section
