Abstract
The invention discloses an automotive half-axle swing forging die repairing process. The repairing process comprises the following steps: a, surface pre-processing: removing a heat fatigue corrosion layer and cracks out of a to-be-repaired surface; b, performing the ultrasonic flaw detection to ensure that the die has no flaw; c, preheating the surface of the die at the preheating temperature of 200-250 DEG C; d, powder injecting and remelting: carrying out spray welding and remelting at the same time; e, slowly cooling after powder injecting and remelting; f, finely processing the repaired surface. The automotive half-axle swing forging die repairing process has the advantages that a repairing plating layer in well combination with a substrate can be obtained, the process is simple and the repairing cost can be reduced.
Description
Technical field
The present invention relates to the mould repair field, be specifically related to a kind of automobile axle shaft rotary forging die repair skill of returning to work.
Background technology
Material is the modified back surface hardening of the automobile axle shaft rotary forging mould of 5CrMnMo, and case hardness 56--58 HRC is in the use; Because continuous 1300 ℃ of high temperature workpiece of spreading, the workpiece heat is constantly passed to mould, makes die surface softening; Soften in order to overcome because of what intensification caused; The water-cooled of having in use not stop to carry out, after long-term the use, die surface produces the many places checking and surperficial bulk is peeled off.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of automobile axle shaft rotary forging die repair skill of returning to work is provided.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of automobile axle shaft rotary forging die repair skill of returning to work may further comprise the steps:
A. surface preparation is removed the heat fatigue corrosion layer and the crackle on surface to be repaired;
B. the mould zero defect is found out in ultrasonic examination;
C. die surface preheating, preheat temperature 200-250 ℃;
D. dust and remelting limit surfacing limit remelting;
E. slow cooling behind the spray fusing;
F. carry out fine finishining to repairing the surface.
Characteristics of the present invention are: can obtain and matrix bond excellent repairing coating, technology is simple, reduces rehabilitation cost.
The specific embodiment
The present invention includes following steps: surface preparation, remove the heat fatigue corrosion layer and the crackle on surface to be repaired; Defectives such as mould flawless are guaranteed in ultrasonic examination; The die surface preheating, preheat temperature 200-250 ℃; Dust and remelting, limit surfacing limit remelting is to guarantee that die surface is smooth smooth; Slow cooling behind the spray fusing; Carry out fine finishining to repairing the surface; Die surface spray-welding coating hardness after the reparation is 60-62HRC, satisfies working condition requirement.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
