Problems solved by technology

[0006] The materials used in current bicycle tripods are mainly made of iron products. The bicycle tripods made of iron products are heavy in weight, poor in strength, and easy to rust; bicycle hubs made of stainless steel are not easy to rust, but they are heavy in weight and strong in strength. also bad

Embodiment Construction

[0019] Below in conjunction with embodiment the method of the present invention is further described.

[0020] An aluminum alloy used in the preparation of a bicycle tripod and a production method thereof. The technical proposal is that the aluminum alloy is composed of aluminum ingots, silicon elements, magnesium elements, and iron elements.

[0021] The specific implementation is as follows:

[0022] 1. Selection of aluminum ingots: select aluminum ingots for remelting with an aluminum content of ≤99.80% as raw materials for production.

[0023] 2. Raw material composition and ratio: aluminum ingot 98.53%, silicon element 0.51%, magnesium element 0.71%, iron element 0.25%.

[0024] 3. Melting: Add aluminum ingots into the melting furnace to melt, and add the above-mentioned various metal elements in sequence according to the process requirements, and then effectively remove the impurities and gases in the melt through degassing and slag removal refining methods to obtain mi...

Abstract

The invention relates to an aluminum alloy for the preparation of a triangular frame of a bicycle and a production method thereof. The aluminum alloy comprises an aluminum ingot, a silicon element, a magnesium element and an iron element, and is then prepared according to a conventional aluminum bar production process. According to the invention, the produced aluminum alloy has the characteristics of high strength, high elongation percentage, high wear resistance, high hardness, favorable corrosion resistance and the like; and a triangular frame of a bicycle manufactured by using the produced aluminum alloy as a raw material also has the above characteristics. Meanwhile, the structural weight of the manufactured triangular frame of a bicycle can be reduced by 50% or above. Besides, the triangular frame of a bicycle is excellent in product quality, and has special features, thus having very wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a novel aluminum alloy, and in particular relates to an aluminum alloy used in preparing a bicycle tripod and a production method thereof. technical background [0002] The bicycle tripod is the skeleton of the entire bicycle. If the strength and rigidity of the bicycle tripod are not enough, it is obvious that the bicycle will fall apart and there is no way for the customer to use it. In this way, the bicycle will have no value, so the bicycle tripod is a a decisive part. [0003] People are fat or thin, and bicycles are sometimes used to transport goods, so how much a bicycle can carry is an important indicator for judging the quality of a bicycle. And it is the tripod that determines the load capacity of the bicycle. Therefore, the maximum carrying capacity of the tripod needs to satisfy the mechanical strength and rigidity of the tripod. [0004] In view of the fact that bicycles are ...
