目前,吉尔——130载重汽车的7.00～20车轮采用两种完全不同的合成工艺。第一种方法是在90吨气动压床上进行的。第二种方法则是在160吨单动液压压床上进行的。图1是装在90吨压床上的冲模。图中的合成工序如下:凹模1中放置轮辋2和轮辐3,轮辋由三个沿圆周均匀分布的压爪4压紧,轮辐由凸模5压入轮辋,轮辋的压力P_1随利用压缩空气管道中气压的轮辐压入力P_2而变,如图2所示。 Currently, Jill - 130 truck 7.00 ~ 20 wheels using two completely different synthetic processes. The first method is carried out on a 90-ton pneumatic press. The second method is carried out on a 160 ton single acting hydraulic press. Figure 1 is a die mounted on a 90-ton press. The synthetic process in the figure is as follows: the rim 1 and the spokes 3 are placed in the die 1, the rim is pressed by three pressing jaws 4 evenly distributed along the circumference, the spokes are pressed into the rim by the punch 5, the pressure P_1 of the rim is changed by using compressed air Pneumatic pressure in the pipeline into the pressure P_2 change, as shown in Figure 2.
