轮转锻造是一种经济的成形方法,坯料金属可全部利用,制件的强度比用切削法所得更高。普通轮转锻造只局限于生产圆截面的制件。采用固定主轴的轮转锻造可以克服这个缺点。此法已发展多年,但仅在最近才引起人们注意。Torrington公司发展了一种新型固定主轴式轮转锻造机。目前用定轴式轮转锻造机生产的制件数量还有限,但其应用范围已很广泛。枪管钻柄是最早用此法生产的制件之一。目前正用此法将管材制成如图1所示的具有
Rotary forging is an economical method of forming, the billet metal can be fully utilized, the strength of the workpiece is higher than the cutting method. Ordinary wheel forging only limited to the production of circular cross-section of the workpiece. Rotary forging with a fixed spindle can overcome this disadvantage. This method has been developed for many years, but only recently attracted the attention of people. Torrington company developed a new fixed-spindle rotary forging machine. At present, the number of parts produced by the fixed-shaft rotary forging machine is still limited, but its application range is very wide. Drill stem is one of the earliest parts produced by this method. This method is currently used to make the pipe shown in Figure 1 has
