Hub manufacturing equipment and hub manufacturing method

Abstract

The embodiment of the invention discloses hub manufacturing equipment and a hub manufacturing method. In order to manufacture a hub through an extrusion forging process and effectively improve the hub performance, the hub manufacturing equipment and the hub manufacturing method are invented. The hub manufacturing equipment comprises a first male die, a flanging die, a side die and a second male die; the first male die and the second male die are oppositely arranged, the flanging die is arranged on the periphery of the first male die in a sleeving manner, and the side die is arranged between the first male die and the second male die; the first male die and the flanging die can move relative to the second male die; when the side die, the first male die and the second male die are matched, a die cavity of the hub is formed along the side die, the first male die and the second male die; when the flanging die, the side die and the second male die are matched, a flanging die cavity of the hub is formed between the inner side of the top of the side die and the flanging die; and the flanging die and the first male die simultaneously or asynchronously move relative to the second male die. The embodiment can be applied to hub manufacturing through materials such as an aluminum alloy, a magnesium alloy, carbon fibers and a composite material.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a wheel hub manufacturing equipment and a wheel hub manufacturing method. Background technique [0002] With the development of the automobile industry, the penetration rate of automobiles has increased year by year, and it has gradually become a common means of transportation for ordinary families. The popularity of family cars has also put forward higher demands on the performance of cars such as light weight, safety, handling and environmental protection. [0003] The wheel hub is one of the most important parts of the car, and the optimization of the performance of the wheel hub plays a vital role in optimizing the performance of the car. At present, lightweight structural materials such as aluminum alloys and magnesium alloys have become the best choice for wheel hub materials due to their light weight and high strength. The wheel hub made of lightweight s...
