Abstract
The invention relates to the technical field of automobile part processing, in particular to a thermal treatment method for a gearbox housing. The thermal treatment method comprises the following steps: wiping greasy dirt on the surface of the gearbox housing, flushing the gearbox housing by use of water, and scrubbing the gearbox housing by use of alcohol; spraying a thermal treating agent which is preheated to a temperature of 40 DEG C to the surface of the gearbox housing, wherein the thermal treating agent is prepared from 12 parts of acrylate emulsion, 10 parts of sodium laureth sulfate, 0.5 part of potassium carbonate, 0.5 part of flavonoid glycoside, 10 parts of cyclohexane and 40 parts of water; putting the gearbox housing into a constant-temperature furnace to dry; putting the gearbox housing into a carburizing furnace for carburizing; and quenching the gearbox housing under pressure of 0.7 MPa, and naturally cooling the gearbox housing when the gearbox is cooled to a temperature of 80 DEG C, thereby completing the thermal treatment. According to the thermal treatment method for the gearbox housing, the surface of the gearbox housing is protected by carrying out thermal treatment after spraying the thermal treating agent and reasonably designing the formula of the thermal treating agent, so that the thermal treatment effect of the gearbox housing and the product quality are improved.
Description
Technical field
The present invention relates to vehicle component processing technique field, be specifically related to a kind of gear box casing heat treatment method.
Background technology
Generally, gear box casing is adding man-hour, and heat treatment is requisite manufacturing procedure. In prior art, gear box casing is made directly carburization step when heat treatment, and is not added with any heat treatment agent as protective agent, and heat treatment efficiency so can be caused low, product of low quality, and product surface causes the defects such as damage.
Summary of the invention
For the technical problem existed in prior art, it is an object of the invention to provide a kind of gear box casing heat treatment method, for achieving the above object, present invention employs techniques below scheme:
A kind of gear box casing heat treatment method, step is as follows:
Step 1., erasing transmission housing surface greasy dirt, then with water rinse 10 minutes, be then used by ethanol clean 5 minutes;
Step 2., the heat treatment agent being previously heated to 40 DEG C is sprayed into the surface of gear box casing, heat treatment agent is made up of 12 parts of acrylic acid ester emulsions, 10 parts of sodium laureth sulfate, 0.5 part of potassium carbonate, 0.5 part of flavonoid glycoside, 10 parts of hexamethylene and 40 parts of water;
Step 3., put in constant temperature oven dry 1 hour, constant temperature in-furnace temperature is 75 DEG C;
Step 4., gear box casing is put into carburizing in carburizer, treatment temperature is 900 DEG C;
Step 5., pressure be under 0.7MPa quench, make its natural cooling when being cooled to 80 DEG C, thus completing heat treatment.
Preferably, the preparation method of the heat treatment agent that 2. described step uses is: first adds 10 parts of sodium laureth sulfate and 20 parts of water in container, stirs 5 minutes; Then 0.5 part of potassium carbonate it is slowly added to, stirring while adding, stir 5 minutes after interpolation; Then 12 parts of acrylic acid ester emulsions and 10 parts of water it are slowly added to, stirring while adding, stir 5 minutes after interpolation; It is then slowly added into 0.5 part of flavonoid glycoside, stirring while adding, stir 5 minutes after interpolation; Finally it is slowly added to 10 parts of hexamethylene and 10 parts of water, stirs 20 minutes.
Beneficial effects of the present invention shows:
1), the heat treatment agent that uses in heat treatment method, its formula is novel in design, rationally, particularly with the addition of a small amount of flavonoid glycoside, it is possible to significantly improve heat treated treatment effeciency, makes the quality of product significantly improve.
2), the preparation method of heat treatment agent, by progressively adding and rationally selecting charging sequence, the solubility property between each material can not only be improved, moreover it is possible to avoid the possibility of particle agglomeration, make the heat treatment safeguard function of heat treatment agent be obviously improved.
3), gear box casing heat treatment method, operating procedure is succinct, heat treated step is carried out by heat treatment agent again after being sprayed, formula by appropriate design heat treatment agent, thus realizing being protected of transmission housing surface, then improve the thermal effectiveness of gear box casing and the quality of product.
