The invention belongs to the technical field of casting machining, and discloses a machining method of a U-shape-liked slender thin-walled cast titanium alloy structural part. The machining method comprises the steps that when an internal shape is finished, three equal-height vice clamps are used for clamping the outline surface of the U-shape-liked slender thin-walled cast titanium alloy structural part; when an external shape is finished, an internal cavity of the U-shape-liked slender thin-walled cast titanium alloy structural part is filled with gypsum and sealed with paraffin, and an outline support lug is pressed to machine the outline surface of the U-shape-liked slender thin-walled cast titanium alloy structural part; hot sizing comprises the maximum deformation of the deformationarea of the U-shape-liked slender thin-walled cast titanium alloy structural part is clamped by a cramp frame, and a titanium base plate is added on the contact surface between the cramp frame and a part; and the clamped U-shape-liked slender thin-walled cast titanium alloy structural part is horizontally placed in a vacuum furnace. According to the provided machining method, the technical problems of large clamping deformation and cutting deformation and large error of boundary dimension and thin-wall dimension of the U-shape-liked slender thin-walled cast titanium alloy structural part can be solved.
Description
technical field [0001] The invention relates to the technical field of processing thin-walled parts, in particular to a processing method for a U-shaped slender thin-walled cast titanium alloy structural part. Background technique [0002] In order to ensure the assembly requirements and control the weight of the thin-walled titanium alloy casting structure, the product needs to be machined after casting. Because the product is slender, thin-walled, and cast, there is internal stress, and the clamping deformation and cutting deformation are large during the processing, resulting in large errors in the product's external dimensions and thin-walled dimensions, and a low pass rate. Contents of the invention [0003] The invention provides a processing method for a U-shaped slender and thin-walled cast titanium alloy structural part, which solves the problem of large clamping deformation and cutting deformation during the processing of a U-shaped slender and thin-walled cast t...
