The invention provides an axle housing blank manufacturing method and device, an axle housing blank, an axle housing, an axle and a vehicle. The axle housing blank manufacturing method comprises the following steps: selecting materials; the initial pipe blank is installed on a pipe blank feeding mechanism of an axle housing blank manufacturing device, and a first core shaft is installed on a core shaft feeding mechanism of the axle housing blank manufacturing device; the initial pipe blank is moved to an auxiliary mold on a mold frame through a pipe blank feeding mechanism, and a first core shaft is moved to the auxiliary mold through a core shaft feeding mechanism and enters the initial pipe blank; starting the auxiliary mold to hit the initial pipe blank; continuing to move the initial tube blank and the first mandrel; when the initial pipe blank and the first mandrel move, the initial pipe blank is forged through the auxiliary die to obtain a special-shaped section pipe blank, and the outer diameter of the special-shaped section pipe blank is increased, and the wall thickness of the local position is reduced; after the initial pipe blank and the first core shaft reach a preset stroke, the special-shaped section pipe blank and the first core shaft are moved reversely; and carrying out radial forging and reducing processing on the pipe blank.

    本发明提供了一种桥壳毛坯制造方法和装置及桥壳毛坯、桥壳、车桥和车辆。桥壳毛坯制造方法包括步骤:选料;将初始管坯安装在桥壳毛坯制造装置的管坯进给机构上,将第一芯轴安装在桥壳毛坯制造装置的芯轴进给机构上;通过管坯进给机构将初始管坯移动到模架上的辅助模具上,通过芯轴进给机构将第一芯轴移动到辅助模具处并进入初始管坯中;启动辅助模具击打初始管坯;继续初始管坯和第一芯轴的移动;在初始管坯和第一芯轴移动时,通过辅助模具锻打初始管坯得到异形截面管坯,实现异形截面管坯的外径增大和局部位置的壁厚减薄;待初始管坯和第一芯轴达到预定的行程后,反向移动异形截面管坯和第一芯轴;进行管坯的径向锻打缩径加工。
