The invention belongs to the technical field of casting processing, and discloses a processing method for a U-shaped slender and thin-walled cast titanium alloy structural part. The outer surface of the alloy structural part; when finishing the shape, the inner cavity of the U-shaped slender thin-walled cast titanium alloy structural part is filled with gypsum, and sealed with paraffin, and the shape lug is pressed. The outer surface of the long thin-walled cast titanium alloy structural part is processed; the thermal correction includes: clamping the maximum deformation of the U-shaped slender thin-walled cast titanium alloy structural part with a bow clamp, and the bow clamp and the part A titanium backing plate is added to the contact surface; the clamped U-shaped elongated thin-walled cast titanium alloy structural part is horizontally placed in a vacuum furnace. The method provided by the invention can solve the technical problems of large clamping deformation and cutting deformation, and large errors in external dimensions and thin-wall dimensions during the processing of the U-shaped slender and thin-walled cast titanium alloy structural parts.
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...
