Manufacturing method for shock absorber aluminum barrel

Abstract

The invention belongs to the technical field of mechanical manufacturing, and particularly relates to a manufacturing method for a shock absorber aluminum barrel. According to the technical scheme adopted by the invention, the manufacturing method for the shock absorber aluminum barrel comprises the steps that (1) aluminum alloy raw materials are placed into a 24-hour constant-temperature smelting furnace; (2)a shock absorber aluminum barrel machining mould and a tilting gravity casting machine are used in cooperation; (3) molten aluminum obtained after aluminum alloy is smelted is poured into the tilting gravity casting machine; (4) the shock absorber aluminum barrel is formed in the tilting gravity casting machine; (5) the mould is cooled; and (6) the part is taken out of the mould. The manufacturing method for the shock absorber aluminum barrel has the advantages that a brand new production method is provided and adopted, the part quality and precision are greatly improved, the production cost is lowered, the service lives of the part and the equipment are prolonged, and the production efficiency and part use safety are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular to a method for manufacturing an aluminum cylinder of a shock absorber. Background technique [0002] The aluminum shock absorber cylinder is one of the most important parts in the commonly used shock absorption components such as motorcycles and electric vehicles. The processing quality of the aluminum shock absorber parts will directly affect the entire shock absorption effect, thus affecting the use of the entire vehicle. comfort and safety. [0003] The traditional shock absorber aluminum cylinder is produced by die-casting. In the production process, the raw material is first melted into a liquid state, and then the required parts are formed by die-casting, and then the inner hole of the assembly is processed through post-processing. machining. However, due to the limitation of production equipment for parts produced by traditional die-casting, the process of...

AI Technical Summary

Problems solved by technology

However, due to the limitation of production equipment for parts produced by traditional die-casting, the process of generating parts is completed by rapid die-casting. In the process of rapid die-casting, due to the uneven temperature, it is impossible to achieve instant exhaust, resulting in production There will be some air bubbles in the parts that come out, making the service life of the parts very limited

In addition, the parts formed by the traditional die-casting method have poor density and are often post-processed, resulting in easier deformation during use

The aluminum cylinder of the shock absorber is a hollow structure. The traditional method is to produce a solid one, and then it can be formed after drilling and other post-processing. The production process is slow, and the defective rate is very high in the production process.
