Abstract
The invention relates to a manufacturing method for improving the yield rate of aluminum alloy wheel hub spin forming. The method comprises the following steps: smelting, casting, rough machining, heating, spinning, heat treatment, and finished product forming. It is characterized in that: During the intermediate step of casting the pier, the rounded corners are machined on the inner rim of the aluminum alloy wheel blank formed by casting. The diameter of the rounded corners is controlled at 6-10 mm. The roughness of the rounded surface of the inner rim of the wheel hub blank is controlled between 3.2 and 6.3. The manufacturing method of the present invention is simple and easy, and by changing the inner rim structure of the aluminum alloy wheel hub blank in the manufacturing process, the spinning process is effectively increased. Improve the fluidity of aluminum alloys and improve the yield of aluminum alloy wheels.
Description
technical field [0001] The invention belongs to the field of aluminum alloy wheel hubs, in particular to a manufacturing method for improving the spinning forming yield of aluminum alloy wheel hubs. Background technique [0002] The following process steps are required in the manufacturing process of aluminum alloy wheel hubs: 1. Melting: melting aluminum ingots into aluminum water, and adding trace elements to improve alloy properties; Aluminum alloy wheel hub blank; 3. Rough machining: machining the positioning hole and positioning surface for blank spinning on a CNC lathe; 4. Heating: heating the blank in a heating furnace to the temperature required by the spinning process; 5. Spinning Pressing: the upper spinning machine spins the rim part until the rim is formed as a whole; 6. Heat treatment: heat-treat the wheel blank after spinning; 7. Finishing: finish the heat-treated wheel blank to form a finished aluminum alloy car hub. The qualified rate of aluminum alloy whee...
