Aluminum alloy buckle and preparation method thereof

Abstract

The invention discloses an aluminum alloy buckle and a preparation method thereof. The preparation method comprises the steps: S1, extrusion forming is conducted, specifically, an aluminum alloy rod is manufactured into a long-strip-shaped aluminum alloy blank with a buckle section shape through an extrusion forming process; S2, machining is conducted, specifically, the long-strip-shaped aluminumalloy blank is cut in the section direction of the long-strip-shaped aluminum alloy blank through machining to obtain an aluminum alloy buckle blank with the required thickness; and S3 surface treatment is conducted, specifically, surface treatment is conducted on the obtained aluminum alloy buckle blank to obtain an aluminum alloy buckle product. According to the preparation method of the buckle,a zinc alloy is replaced with an aluminum alloy, not waste material is generated in the production process, and the production cost is remarkably lowered; and the surface of the aluminum alloy blankprepared through the extrusion forming process is smooth and free of burrs, the aluminum alloy blank does not need to be polished, the machining process is reduced, in addition, the surface coloring performance of the aluminum alloy texture buckle blank is good, and the decorative requirement of various buckle products can be met better.

Description

technical field [0001] The invention relates to the technical field of metal hanging buckle processing, in particular to an aluminum alloy hanging buckle and a preparation method thereof. Background technique [0002] At present, there are two methods of forming metal hanging buckles such as key chains, luggage buckles, and carabiners: die-casting and stamping. After the blanks are formed, various metal fasteners with rich colors are prepared through surface treatment processes such as electroplating or painting. finished product. Among them, stamping is to use machines such as punching machines to turn semi-finished products into finished products, and die-casting is to heat metal into a liquid state and press it into a mold to form a product that is the same as the mold. The choice of forming method is related to the product structure. The two forming methods are mainly used to obtain metal fastener products with different structures. [0003] The stamping method is main...
