Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] A method for processing lightweight aluminum alloy chassis parts, such as figure 2 As shown, for a forging that only needs to be forged once, the steps include:

[0024] S1. Use the T6 aluminum alloy as the billet blanking, put the billet into the heating equipment and heat it at 50-150°C below the solid solution temperature, and the heating time and holding time are 3-30 minutes;

[0025] S2, heating the blocker to 300-550°C;

[0026] S3, taking out the blank and transferring it to the pre-forging die to form it into a forging;

[0027] S4, the forging is taken out, then water quenched to room temperature;

[0028] S5. Cut the edge after cooling the forging, and then perform machining treatment to obtain the final product.

[0029] The billet heated in step 1 is an age-hardened aluminum alloy billet, and after the forging and pressing are c...

Abstract

The invention relates to a machining method of a lightweight aluminum alloy chassis part. A T6 state aluminum alloy is used as a blank for blanking, the blank is heated in a heating device till temperature is lower than the solid solution temperature by 50-150 DEG C; the heating time and the heat preserving time are 3-30 min, a mold is heated to 300-550 DEG C, and the blank is transferred into themold and made to form a forged piece; then the forged piece is taken out and subjected to water quenching till room temperature is achieved; and then the forged piece is subjected to edge cutting after cooling, machining treatment is performed, and a final product is obtained. Because the blank is the aging hardened state aluminum alloy, it is not needed to perform subsequent solid solution agingheat treatment reinforcing essential for a traditional hot die forging process, and therefore the forming production period is shortened, and the production efficiency is greatly improved; and meanwhile, the using performance of products can be guaranteed, and cost is also reduced.

Description

technical field [0001] The invention belongs to the field of thermal forming of aluminum alloy forgings, and in particular relates to a processing method for lightweight aluminum alloy chassis parts. Background technique [0002] In the automobile manufacturing industry, the aluminum alloy body is usually used to reduce the weight of the automobile structure, so as to achieve the purpose of energy saving and environmental protection. Therefore, forged forgings and punching parts that can be heat-treated to strengthen aluminum alloys have been widely used in automobile manufacturing. Although its amount is not large (accounting for only about 1.4% of the total amount of aluminum used), it is a part that bears large static loads and dynamic loads, so it is very important. [0003] At present, when the aluminum alloy chassis parts are formed by die forging, the process flow is long. For example, if figure 1 As shown, the domestic aluminum alloy die forging forming process is ...
