Aluminum alloy material used for manufacturing bicycle frame and production process for aluminum alloy material

Abstract

The invention discloses an aluminum alloy material used for manufacturing a bicycle frame and a production process for the aluminum alloy material. The production process comprises the following steps: firstly, putting a small part of aluminum leftover waste materials into a furnace for bottoming, and then, adding Si, Fe, Cu, Mn, Cr and V according to the components; carrying out ignition heating and smelting while fire is needed to be ceased and waste materials are added, repeating the step until all wastes are added into the furnace, and controlling the temperature of molten aluminum to be lower than 950 DEG C; adding a fluxing medium into the furnace, slagging off from the interior of the furnace, and completely slagging visible impurities on the surface of the molten aluminum off the furnace; adding magnesium into a prefabricated iron cage, and then, inserting the prefabricated iron cage into the molten aluminum until magnesium is completely molten; and refining, carrying out test in front of the furnace, slagging off for the second time, stewing, and carrying out cast molding. The aluminum alloy material can improve the mechanical strength and the mechanical property of the bicycle frame, and can reduce the weight of the bicycle frame.

Description

technical field [0001] The invention relates to alloy materials, in particular to an aluminum alloy material used for manufacturing a bicycle frame and a production process thereof. Background technique [0002] Aluminum alloy is the most widely used metal structural material in the industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy is increasing. The research on aluminum alloy materials is also in-depth, and aluminum alloy is the most widely used alloy. Especially in the bicycle industry, the quality and strength requirements of the bicycle frame are constantly improving, and the bicycle frame produced by aluminum alloy forging materials has begun to be valued. In the prior art, the bicycle frame is generally made of aluminum alloy material through pressure casting. The aluminum alloy of this material has not been p...

AI Technical Summary

Problems solved by technology

Especially in the bicycle industry, the quality and strength requirements of the bicycle frame are constantly improving, and the bicycle frame produced by aluminum alloy forging materials has begun to be valued. In the prior art, the bicycle frame is generally made of aluminum alloy material through pressure casting. The aluminum alloy of this kind of material has not been processed again, and the metal structure has not been improved, and there are many problems such as low mechanical properties.
