Problems solved by technology

[0002] At present, the general production process of wheel hubs is casting, heat treatment, machining, various inspections, painting, packaging and storage, such as figure 1 It is a partial cross-sectional view of the tire ring of a general cast wheel hub product. Due to the limitation of casting production, the wall thickness at A' in the figure is about 6mm, and the wall thickness at B' is about 5mm. The wheel hub casting is tall and thin, and the castability Unstable, the thicker part of the finished tire ring makes the whole wheel hub heavier, and it is easy to cause poor air leakage due to unstable casting, and the tensile strength and elongation are relatively ordinary, and the strength is not good enough
This production process cannot produce high-strength and lightweight wheels

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] see figure 2 As shown, the present invention discloses a molding method of an aluminum alloy wheel hub. The rolling step is added in the molding process, thereby improving the arc angle of the rib tail and the feeding of the mounting surface during casting production, good castability, and light weight of the wheel hub. Its specific molding steps are as follows:

[0031] (1) Casting: Aluminum alloy raw materials are cast into wheel hub blanks, and the shape of the blank molds must be designed to be short and fat according to the rolling requirements; image 3 It is a partial cross-section...

Abstract

The invention discloses a forming method for an aluminum alloy hub, which comprises the following forming steps: casting, calendering, heat treating, machining, testing, coating, and packing and storing. According to the forming method, feeding for a rib tail arc angle and a mounting face is improved during foundry manufacturing; the castability is good; the strength is effectively improved; and the thickness of a finished rim is thinner than that of a normal rim, so as to achieve the effect that the hub is light in weight, and is convenient to use and transport.

Description

technical field [0001] The invention relates to a manufacturing method of a wheel hub, in particular to a forming method of an aluminum alloy wheel hub. Background technique [0002] At present, the general production process of wheel hubs is casting, heat treatment, machining, various inspections, painting, packaging and storage, such as figure 1 It is a partial cross-sectional view of the tire ring of a general cast wheel hub product. Due to the limitation of casting production, the wall thickness at A' in the figure is about 6mm, and the wall thickness at B' is about 5mm. The wheel hub casting is tall and thin, and the castability It is relatively unstable, and the thicker part of the finished tire ring makes the entire wheel hub heavier. Due to the unstable castability, it is easy to cause poor air leakage, and the tensile strength and elongation are relatively ordinary, and the strength is not good enough. This production process cannot produce high-strength and lightw...
