Abstract

The invention discloses an aluminum alloy hub and a preparation method thereof, wherein the preparation method comprises the following steps: (1) mixing aluminum powder, iron powder, manganese powder, silicon powder, copper powder and zinc powder, then smelting the aluminum powder, the iron powder, the manganese powder, the silicon powder, the copper powder and the zinc powder, and obtaining molten aluminum M; (2) adding slag-cleaning agent and refining agent to the molten aluminum M, then obtaining molten aluminum N; (3) moulding the molten aluminum N by pouring, then obtaining the aluminum alloy hub. By means of the method, the low qualified rate of finished products caused by easily appearing cracks in the surface of the hub prepared of conventional aluminum alloy material can be avoided.

Description

Technical field [0001] The invention relates to the field of wheel hub manufacturing, in particular to an aluminum alloy wheel hub and a preparation method thereof. Background technique [0002] Wheel hubs are also called rims, wheels, and tire bells. They are cylindrical metal parts with the inner profile of the tire supporting the tire and centered on the shaft. There are many types of hubs according to their diameter, width, molding method, and material. The material and preparation method of the hub determine the quality of the hub, and the surface of the hub made of conventional aluminum alloy materials is prone to cracks, resulting in a low pass rate of the finished product. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide an aluminum alloy wheel hub and a preparation method thereof that have a good force bearing effect and are not prone to cracks on the surface after processing, so as to greatly improve the qualified rate of the fi...
