The invention belongs to the technical field of hub forging, and particularly relates to a new energy automobile hub forging process. A hole cutting device used in the process comprises a cylindricalworkbench, a bracket is arranged at the top end of the workbench, the bracket is of a cylindrical structure, two or more leaking grooves are formed in the top end of the bracket at equal intervals inthe circumferential direction of the bracket, a taking-out hole is formed in the side wall of the bracket, a circular ring is rotationally mounted on the outer side wall of the workbench, a gear ringis fixed to the outer side wall of the circular ring, a drive motor is fixed to the side wall of the workbench, a gear disc is fixed to the output shaft end of the drive motor, and the gear disc is engaged with the gear ring; and holes are cut in a hub prototype, so that the redundant portion of the hub prototype is cut off, on one hand, materials needed for manufacturing a hub are saved, the production cost is reduced, and on the other hand, the holes are cut in the hub, so that the working task amount of a subsequent lathe is reduced, the forging efficiency of the hub is improved, and the production efficiency of the hub is further improved.

    本发明属于轮毂锻造技术领域,具体的说是一种新能源汽车轮毂锻造工艺,该工艺中使用的切孔装置包括圆柱状的工作台,所述工作台顶端设有托架,所述托架为圆柱状结构,所述托架顶端沿其周向等距离设有两个以上的漏槽,所述托架侧壁设有取出孔,所述工作台外侧壁转动安装有圆环,所述圆环的外侧壁固定有齿环,所述工作台侧壁上固定有驱动电机,所述驱动电机的输出轴端固定有齿盘,所述齿盘与齿环互相啮合;本发明通过在轮毂雏形上切孔,使得轮毂雏形多余的部分被切下,一方面节省了制造轮毂所需的材料,降低了生产成本,另一方面,在轮毂上切孔减少了后续车床的工作任务量,从而提高了轮毂的锻造效率,进而提高了轮毂的生产效率。
