Abstract

The invention relates to a titanium alloy thin-wall hemispheroid machining technology, in particular to a titanium alloy thin-wall hemispheroid machining method which comprises the steps that a hemispheroid blank is obtained; performing rough machining on the hemispheroid blank by taking the flange edge of the hemispheroid blank as a reference; a flange block is obtained, and the flange block is welded to the flange edge subjected to rough machining; and with the flange block as the reference, the hemispheroid blank is subjected to finish machining to the final size. The flange edge serves as the rough machining standard, rough machining is carried out on the molded surface of the hemispheroid blank, the flange block is obtained, the flange block is welded to the flange edge of the hemispheroid, the flange block serves as the finish machining standard, and finish machining is carried out on the hemispheroid blank. The wall thickness size, the height size, the inner hole size and the outer circle size of the hemispheroid can be accurately controlled, so that the design requirement of the titanium alloy thin-wall hemispheroid is met, and the use performance of the titanium alloy thin-wall hemispheroid and the assembly precision of an assembly are guaranteed.

Description

technical field [0001] The invention relates to a technology for processing a titanium alloy thin-walled hemisphere, in particular to a method for processing a titanium alloy thin-walled hemisphere. Background technique [0002] Hemispherical parts are the key structural components of aerospace products, mainly used for assembly and welding of gas cylinders, storage tanks and other components, and are used to store high-pressure nitrogen and propellants in the attitude control power system. Due to the high requirements for storage and use of gas cylinders and storage tanks, generally hemispherical parts are required to be light in weight, high in strength, and able to withstand high pressure to ensure the strength of blasting and pressure test requirements. [0003] However, the processing of titanium alloy materials is difficult, and it is difficult to control the dimensional accuracy of thin-walled parts. Therefore, it is necessary to propose a method for processing titan...
