Aluminum alloy extruding machining technology for shovel tooth radiator and aluminum alloy profile thereof

Abstract

The invention relates to the technical field of aluminum alloy machining, in particular to an aluminum alloy extruding machining technology for a shovel tooth radiator and an aluminum alloy profile thereof. The aluminum alloy extruding machining technology for the shovel tooth radiator comprises sequentially the steps of raw material smelting, extruding forming, shovel tooth machining and aging heat treatment. The raw material smelting step comprises component optimization, wherein a 6063 aluminum alloy is adopted as a base material, and calculated according to the weight percentage, raw material components of the optimized aluminum alloy comprise 0.49-0.52% of magnesium, 0.37-0.40% of silicon and less than or equal to 0.13% of iron. According to the aluminum alloy extruding machining technology for the shovel tooth radiator, with the 6063 aluminum alloy adopted as the base material, through component optimization and control of the raw material smelting step, the technology is applicable to the extruding technology an shovel tooth machining; and aluminum alloy of the shovel tooth radiator prepared can be extruded and machined into the shovel tooth radiator with both property and standards qualified.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to an aluminum alloy extrusion process for a shovel-tooth radiator and an aluminum alloy profile thereof. Background technique [0002] As a device for conduction and heat dissipation, radiators have been widely used in wind power, industrial frequency conversion, casings, homes, automobiles, etc. Radiators are roughly divided into cast iron, steel, and aluminum alloys according to their materials. Among them, aluminum alloy radiators have the advantages of light weight, corrosion resistance, beautiful appearance, and diverse shapes, and have been favored by more and more people in recent years. [0003] The main production method of aluminum alloy radiator is one-time extrusion molding. Its advantage is that the process is simple, but it has higher requirements for extrusion dies. Generally speaking, when the ratio of the multiple of the radiator, that is, the m...

AI Technical Summary

Problems solved by technology

[0005] Although the shovel tooth radiator has the above advantages, it has extremely high requirements on the material, and must have a uniform metallographic structure and moderate hardness, otherwise it will easily lead to bent teeth, broken teeth, uneven tooth surfaces, and serious wear and tear on the extruded profile.

[0006] If there is no suitable extrusion process, it is only after the shoveling process that we can know whether the aluminum alloy extruded profiles produced by the previous extrusion process are qualified, and the detection is lagging. Therefore, the shoveling radiator of the current technology is difficult Achieve stable mass production
