Embodiment Construction

[0014] The technical solutions of the present invention will be described in detail by the following examples. It should be understood that the following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be interpreted as a description of the technical solutions of the present invention. limits.

[0015] In each possible embodiment of the present invention, the difference is the ratio of each component in the aluminum alloy material, and the rest of the difference is basically no. Therefore, in this application, the various ratios of aluminum alloy materials are carried out within the scope of the technical solution, which will not be repeated here. That is to say, within the scope of this application, aluminum alloys can be freely mixed. ratio, and will not affect the realization of the technical solution of the present application.

Abstract

The invention relates to a forging and pressing method of aluminium alloy with good forging and pressing property. The aluminium alloy with good forging and pressing property is obtained by adopting the forming and pressing method; two-stage isothermal tempering is carried out in an aluminium alloy tempering stage; the forging temperature of the aluminium alloy material is 330-380 DEG C; after the forging is ended, the isothermal water quenching is carried out.

Description

technical field [0001] The invention belongs to the field of metal material processing, and specifically relates to a forging method for aluminum alloys with good forging properties. Background technique [0002] In order to make the aluminum alloy have good forging properties, lead is generally added to the aluminum alloy to improve its forging properties. However, due to the harm of lead to the environment and human body, it is necessary to find aluminum alloy materials that can replace lead. [0003] The prior art proposes to add tin and bismuth to the aluminum alloy material to manufacture the aluminum alloy with good forging properties, but compared with the lead-aluminum alloy, its brittleness increases, and the aluminum alloy will have cracks during hot forging. [0004] In order to overcome the above-mentioned defects, another technology proposes to reduce the brittleness in the aluminum alloy by adding zinc to the aluminum alloy added with tin and bismuth, and redu...
