Embodiment 1

[0017] The invention proposes a forging process of an aluminum alloy wheel hub, which includes the following steps: S10: heating the pre-processed square aluminum alloy blank to 150°C, and keeping it warm for 0.2 hours; S20: heating the square blank for the first time to 300°C, hold for 0.3 hours, and then heat for the second time at 400°C, hold for 0.4 hours; S30: preheat the mold of the forging press at 200°C, hold for 0.2 hours; S40: put The square blank in step S20 is placed in the wheel hub mold of the forging press in step S30 for forging, and the forging temperature is 440°C to form a disc-shaped wheel hub blank; S50: after the wheel hub blank is cooled, trim it , polishing treatment, and spray wear-resistant powder to get the finished wheel hub.

Embodiment 2

[0019] The present invention proposes a forging process of an aluminum alloy wheel hub, which includes the following steps: S10: heating the pre-processed square aluminum alloy blank to 260°C and keeping it warm for 0.5 hours; S20: heating the square blank for the first time to 350°C, hold for 0.5 hours, and then heat for the second time at 60°C, hold for 0.6 hours; S30: preheat the mold of the forging press at 300°C, hold for 0.4 hours; S40: put The square blank in step S20 is placed in the wheel hub mold of the forging press in step S30 for forging, and the forging temperature is 480°C to form a disc-shaped wheel hub blank; S50: after the wheel hub blank is cooled, it is trimmed , polishing treatment, and spray wear-resistant powder to get the finished wheel hub.

Embodiment 3

[0021] The invention proposes a forging process of an aluminum alloy wheel hub, which includes the following steps: S10: heating the pre-processed square aluminum alloy blank to 200°C, and keeping it warm for 0.4 hours; S20: heating the square blank for the first time to 320°C, hold for 0.4 hours, and then heat for the second time at 440°C, hold for 0.5 hours; S30: preheat the mold of the forging press at 250°C, hold for 0.3 hours; S40: put The square blank in step S20 is placed in the wheel hub mold of the forging press in step S30 for forging, and the forging temperature is 460°C to form a wheel hub blank with a disc-shaped structure; S50: Trim the edge of the wheel hub blank after it is cooled , polishing treatment, and spray wear-resistant powder to get the finished wheel hub.

Abstract

The invention discloses a forging process of an aluminum alloy wheel hub. The forging process comprises the following steps that a pre-machined square aluminum alloy blank material is heated to 150 DEG C to 260 DEG C, and heat preservation is carried out for 0.2 hour to 0.5 hour; the square blank material is heated to 300 DEG C to 350 DEG C for the first time, heat preservation is carried out for0.3 hour to 0.5 hour, then second heating is carried out, the temperature ranges from 400 DEG C to 460 DEG C, and heat preservation is carried out for 0.4 hour to 0.6 hour; a mold of a forging machineis pre-heated, wherein the heating temperature ranges from 200 DEG C to 300 DEG C, and heat preservation is carried out for 0.2 hour to 0.4 hour; the square blank material in S20 is placed in the forging mold of the forging machine in S30 to be forged, wherein the forging temperature ranges from 440 DEG C to 480 DEG C, and a hub blank of a disc-shaped structure is formed; and after the hub blankis cooled, edge cutting and polishing are carried out on the hub blank, wear-resisting powder is sprayed, and the finished hub is obtained. According to the forging method, the utilization rate of aluminum alloy is increased, the structural strength is high, and safety is high.

Description

technical field [0001] The invention relates to the field of forging, in particular to a forging process of an aluminum alloy wheel hub. Background technique [0002] As one of the important components in the vehicle driving system, the wheel hub carries the weight of the vehicle, and the quality of the wheel hub directly affects the life of the wheel and the safety of the passengers. In the prior art, the utilization rate of raw materials in the forging of automobile wheel hubs is not high, the structural strength is insufficient, fractures are prone to occur, and the safety is not high. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a forging process for a wheel hub. The forging method improves the utilization rate of aluminum alloy, has high structural strength and high safety. [0004] In order to achieve the above object, the present invention proposes a forging process of an aluminum alloy w...
