Preparation method of aluminum alloy spherical crown, corrosion-resistant aluminum alloy spherical crown and support
The invention provides a preparation method of an aluminum alloy spherical crown, a corrosion-resistant aluminum alloy spherical crown and a support. The preparation method of the aluminum alloy spherical crown comprises the following steps: S1, blanking; s2, thermal forming; s3, solution treatment; s4, cold deformation is conducted, specifically, the blank obtained in the S3 is put into a second mold, the second mold is completely filled with the blank, cold press forming is conducted, and the cold deformation amount is 2-4%; and S5, aging. According to the preparation method of the corrosion-resistant aluminum alloy spherical crown, cold deformation is carried out after solution treatment, thermal stress and residual stress generated by solution treatment can be offset, and the dimensional stability of the machined spherical crown is improved; the element composition of the aluminum alloy bar is optimized, so that the prepared aluminum alloy spherical crown has higher strength, hardness and corrosion resistance; through the sizes of the first mold and the second mold, the deformation of each part of the spherical crown blank is accurately controlled, crystal grains are uniform, and the problems that hot die forging metal of the aluminum alloy spherical crown blank is not fully filled and demolding is difficult are solved.
