Abstract
The present invention relates to automobile air conditioner compressor Crankshaft Machining technical field, a kind of surface heat-treatment process of automobile air conditioner compressor bent axle, bent axle is placed in retort, and the part that bent axle is in addition to two end faces is all exposed in retort, then in retort, it is filled with nitrogen, and inner air is all discharged；Then retort being warming up to 1,000 1200 DEG C, the persistent period of this temperature is 20 30min, then the temperature of retort is reduced to 680 750 DEG C, is incubated 3 5h；Then take out bent axle in liquid nitrogen, be quickly cooled to room temperature.The surface heat-treatment process of the automobile air conditioner compressor bent axle obtained by the present invention, heat under full nitrogen state and be incubated, and be rapidly heated also with liquid nitrogen in cooling procedure, can effectively guarantee that crankshaft surface processes uniformly, do not have the situation of oxidation, product quality is high, and stability is high.
Description
Technical field
The present invention relates to automobile air conditioner compressor Crankshaft Machining technical field, especially a kind of automobile air conditioner compressor bent axle
Surface heat-treatment process.
Background technology
Heat treatment for automobile air conditioner compressor bent axle all uses traditional heat treatment method, in its processing procedure at present
Easily there is the situation of the trickle oxidation in local in surface, and processes uneven for crankshaft surface, easily occurs that crackle etc. does not conforms to
Lattice situation, causes product qualified rate relatively low.
Summary of the invention
The invention aims to solve the deficiency of above-mentioned technology and provide a kind of operation simple, heat treatment quality high and
The surface heat-treatment process of the automobile air conditioner compressor bent axle that qualification rate is high.
In order to achieve the above object, the Surface heat-treatent side of a kind of automobile air conditioner compressor bent axle designed by the present invention
Method, is placed on bent axle in retort, and the part that bent axle is in addition to two end faces is all exposed in retort, then in retort
It is filled with nitrogen, and inner air is all discharged；Then retort is warming up to 1000-1200 DEG C, during this temperature lasting
Between be 20-30min, then the temperature of retort is reduced to 680-750 DEG C, is incubated 3-5h；Then take out bent axle quick in liquid nitrogen
It is cooled to room temperature.
In retort, the temperature of regional is always consistent.
The surface heat-treatment process of the automobile air conditioner compressor bent axle obtained by the present invention, heats under full nitrogen state
And be incubated, and be rapidly heated also with liquid nitrogen in cooling procedure, can effectively guarantee that crankshaft surface processes uniformly, will not
There is the situation of oxidation, product quality is high, and stability is high.
Detailed description of the invention
The present invention is further described by the following embodiment.
Embodiment 1:
The surface heat-treatment process of a kind of automobile air conditioner compressor bent axle that the present embodiment describes, is placed on bent axle in retort,
And the part that bent axle is in addition to two end faces is all exposed in retort, in retort, then it is filled with nitrogen, and by inner air
All discharge；Then retort being warming up to 1140 DEG C, the persistent period of this temperature is 28min, then the temperature of retort is dropped
As little as 720 DEG C, it is incubated 4h；Then take out bent axle in liquid nitrogen, be quickly cooled to room temperature.
In retort, the temperature of regional is always consistent.
Embodiment 2:
The surface heat-treatment process of a kind of automobile air conditioner compressor bent axle that the present embodiment describes, is placed on bent axle in retort,
And the part that bent axle is in addition to two end faces is all exposed in retort, in retort, then it is filled with nitrogen, and by inner air
All discharge；Then retort being warming up to 1050 DEG C, the persistent period of this temperature is 25min, then the temperature of retort is dropped
As little as 700 DEG C, it is incubated 3.5h；Then take out bent axle in liquid nitrogen, be quickly cooled to room temperature.In retort, the temperature of regional begins
Keep consistent eventually.
Claims (2)
1. a surface heat-treatment process for automobile air conditioner compressor bent axle, is characterized in that: be placed in retort by bent axle, and bent
Axle part in addition to two end faces is all exposed in retort, is then filled with nitrogen in retort, and inner air is whole
Discharge；Then retort being warming up to 1000-1200 DEG C, the persistent period of this temperature is 20-30min, then by the temperature of retort
Degree is reduced to 680-750 DEG C, is incubated 3-5h；Then take out bent axle in liquid nitrogen, be quickly cooled to room temperature.
The surface heat-treatment process of a kind of automobile air conditioner compressor bent axle the most according to claim 1, is characterized in that: retort
The temperature of interior regional is always consistent.
