滚辗与辊压是两种与传统成形方法不同的新方法。下面探讨这两种方法的特点和采用可能性。滚辗滚辗制品一般是具有光滑的环形外表面和内部有径向肋板的中空零件。采用的毛坯是高度不同的锻造或铸造环形件,其体积几乎与成品锻件相同。带肋板的中空件的成形过程如图1所示。图中只表示出直接起成形作用的工具,这儿是指一个环形的模具和成形辊。模具的内径相当于成品锻件的外径。装在固定架内的模具由单独传动装置传动。图上所见的轴,一方面起滚辗成环的作用,另一方面也起肋板成
Rolling and rolling are two different methods of forming a new method. The following discusses the features and possibilities of these two approaches. Rolling products are generally hollow parts with a smooth annular outer surface and radial ribs inside. The blanks used are highly forged or cast rings that are almost the same size as the finished forgings. The ribbed hollow part forming process is shown in FIG. 1. The figure shows only the tool that acts directly to shape, here a ring mold and forming roll. The inner diameter of the die is equivalent to the outer diameter of the finished forgings. The mold mounted in the holder is driven by a separate actuator. The shaft seen on the figure, on the one hand, plays the role of roller rolling, on the other hand, it also acts as a ribbed plate
