New energy automobile hub forging process

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of wheel hub forging, in particular to a new energy vehicle wheel hub forging process. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also known as rims, steel rims, wheels, and tire bells. There are many types of hubs according to diameter, width, molding method and material. [0004] There are also some technical solutions for forging automobile hubs in the prior art, such as a Chinese patent with application number 2019103079304, which discloses a forging process for alum...

Problems solved by technology

[0004] There are also some technical solutions for forging automobile hubs in the prior art, such as a Chinese patent with application number 2019103079304, which discloses a forging process for aluminum alloy wheel hubs, which improves the utilization rate of aluminum alloys and reduces the The production cost of the wheel hub is reduced, the forging precision is improved, and the structural strength is high. However, in the process of manufacturing the wheel hub of new energy vehicles, multiple through holes need to be turned out, which not only increases the work tasks of the lathe, but also causes waste of the wheel hub material, thus reducing the cost. The forging efficiency of the wheel hub, accordingly, the present invention proposes a new energy vehicle wheel hub forging process
