212摇臂轴形状并不复杂(图1),它的杆部与一扇形块相连,设计锻造工艺时,必须考虑偏心聚料效果。选择不同的工艺,其生产效率及经济效益也大不相同。下面就212摇臂轴的三种主要锻造工艺:锤上模锻、锻压机立镦锻和平锻工艺进行分析比较。一、锻件图图2、图3、图4分别为锤上模锻、锻压机立镦锻和平锻工艺的锻件图。从图中可以看出,锻件的形状、机械加工余量及公差与它相应的锻造工艺密切要关。我们先撇开 212 rocker shaft shape is not complicated (Figure 1), its rod connected to a sector, the design of the forging process, you must consider the eccentric polymer effect. Choose a different process, its production efficiency and economic benefits are also very different. The following 212 on the rocker shaft of the three main forging process: hammer on forging, forging upsetting upset forging and forging process analysis and comparison. First, the forgings Figure 2, Figure 3, Figure 4 were hammer on forging, forging machine upsetting forging and forging process forgings map. As can be seen from the figure, forgings shape, machining allowance and tolerance and its corresponding forging process are closely related. Let us put aside
