Embodiment Construction

[0014] The material of the thin-walled casing is GH907, and the design diameter of the thin-walled casing is The amount of wear is 0.03mm on one side, and the maximum deformation is 0.12mm on one side. The repair method is as follows:

[0015] (1) Use CNC lathe to turn the worn and deformed thin-walled receiver stop, with a unilateral machining allowance of 0.15 mm, round the stop and ensure the thickness of the spray coating in the next process;

[0016] (2) Plasma spray NiCrAl coating on the processed seam with a thickness of 0.3mm;

[0017] (3) Using a CNC lathe, the NiCrAl coating is turned with an outer circular cutting full-arc insert (R1.5, the cutting edge arc is 250°), and the machining process is completed in three passes, and the machining allowance of the first knife is 0.02mm ;The machining allowance of the second knife is 0.08mm; the machining allowance of the third knife is 0.05mm, and the seam size is machined to the design size Complete the wear and deform...

Abstract

The invention relates to a method for restoring abrasion and deformation of a spigot of a thin-wall cartridge receiver. According to the technical scheme, the method for restoring the abrasion and the deformation of the spigot of the thin-wall cartridge receiver comprises the following steps: machining the abraded and deformed spigot of the thin-wall cartridge receiver, spraying a NiCrAl coating on the spigot and lathing the NiCrAl coating. According to the method for restoring the abrasion and the deformation of the spigot of the thin-wall cartridge receiver, the problem of restoring the failure of the spigot of the thin-wall cartridge receiver made from GH907 materials is solved, and meanwhile it is guaranteed that the cartridge receiver meets the requirements of design paper after being repaired. In this way, the service life of the cartridge receiver is prolonged so that the cartridge receiver can continue being used, and therefore production cost is saved.

Description

technical field [0001] The invention relates to a method for repairing parts, in particular to a method for repairing wear and deformation of a thin-walled casing. Background technique [0002] The casing parts have complex structures, large diameters, thin walls, and are mostly difficult-to-machine materials, which are expensive. The dimensional accuracy and technical conditions of the seam of the thin-walled casing are relatively high, and it is not easy to repair after the seam is worn and deformed. Therefore, it is the development trend of engine repair technology in actual production to study the repair technology after wear and deformation of the seam of the thin-walled casing. The research of the present invention on the wear and tear repairing technology of the thin-walled casing whose material is GH907 has not been carried out in China before, and it is still the first case. Contents of the invention [0003] The purpose of the present invention is to provide a ...
