Abstract

The invention relates to a rotary pressing processing technology of an aluminum alloy hub. The rotary pressing processing technology of the aluminum alloy hub is used for performing powerful rotary pressing and forming on a casting / forging blank. The technology comprises a rotary pressing processing of a mandrel, rotary pressing designing of a blank and powerful rotating processing, wherein the rotary pressing processing of the mandrel is that the molded surface of the mandrel is grinded until the smoothness is Ra0.4-Ra0.8 microns; the rotary pressing designing of the blank is that a hub rotary pressing part solid model is drawn through solid modeling software, and the metal volume is calculated, and then the die forging rotary pressing blank is calculated based on the volume non-deformation design and the blank is casted; the powerful rotating processing includes first rotary pressing and secondary powerful rotating forming; the first rotary pressing is to accurately forge the blank;and the secondary powerful rotating forming is to process a hub product through a numerically controlled workshop. With the adoption of the technology, the rotary pressing efficiency and quality of the hub can be improved; and the mechanical performance of a tyre ring can be improved.

Description

technical field [0001] The invention relates to the technical field of processing technology, in particular to an aluminum alloy wheel hub spinning processing technology. Background technique [0002] In the spinning wheel hub processing technology in the prior art, the low-pressure casting rough material blank is directly heated and spun. The Chinese patent "An Integral Aluminum Alloy Spinning Wheel Hub and Its Manufacturing Method" discloses a manufacturing method of a spinning wheel hub. The initial blank is machined with a center hole and an outer circular edge, and then placed on a spinning machine for spinning. , and then finish machining on CNC machine tools. In the comparison document, the rough material is directly heated, the force on the tire ring is uneven during the spinning process, and the mechanical performance is unstable; the automatic positioning accuracy is not accurate, and the production process is easily interrupted; resulting in irregular post-hangin...
