[0040] Example 1: Aluminum alloy wheel hot spinning process to improve the overall strength of the wheel. The main process of the process is melting-casting preforming-homogenization treatment-heating spinning-preheating treatment-shot peening-spinning-heat treatment- Shot peening-machining-coating; specifically:

[0041] Melting: Prepare aluminum alloy according to requirements and use electric melting furnace for melting;

[0042] Casting preforming: use pressure casting to make liquid metal fill the cavity at a very high speed under high pressure, and solidify under pressure to obtain castings;

[0043] Homogenization treatment: each processed hub must be polished on the deburring machine, and then carefully polished by workers to polish the casting surface of the workpiece to be smooth and flat;

[0044] Heating spinning: at high temperature, the workpiece is heated, and the wire is spun. Before spinning, the workpiece is heated. During the heating process, a layer of str...

Abstract

Aluminum alloy wheel hot spinning process to improve the overall strength of the wheel. The main process of the process is melting-casting pre-forming-homogenization treatment-heating spinning-preheating treatment-shot peening-spinning-heat treatment-shot peening-machine Plus‑coating. The plastic deformation of hot spinning can bridge the fine loose defects, thereby improving the mechanical properties of the wheel hub. The new casting and spinning process greatly improves the overall strength and corrosion resistance of the wheel, while the machining allowance is greatly reduced, and the service life and safety of the wheel are improved. Significantly improved, which is conducive to vehicle weight reduction and fuel saving, and the production cost of wheels is reduced.

Description

Technical field: [0001] The invention relates to a common aluminum alloy wheel hub, in particular to a hot spinning process for the aluminum alloy wheel hub to improve the overall strength of the wheel. Background technique: [0002] With the rapid development of the automobile industry, the requirements for energy saving and consumption reduction of modern automobiles are constantly increasing, safety and environmental protection regulations are becoming stricter, and the requirements for automobile lightweight are more urgent. Due to the wide use of aluminum alloy wheels, its beautiful, atmospheric and changeable shape design also adds a lot to the car. At present, in the Chinese auto market, the utilization rate of aluminum alloy wheels for cars has reached at least 70 shares of the total car market. According to relevant statistics, in 2003 this proportion was about 50 copies. Aluminum alloy is light in weight, high in strength, good in formability, moderate in price, ...
