Abstract
The invention discloses a kind of processing technology of spline housing, concrete technology step are as follows：The first step：Blanking, which is carried out, from the round steel that material is 20CrMnTi forms blank；Second step：Workpiece after roughing carries out modifier treatment, and workpiece is to slowly warm up into 800 DEG C, then annealed；3rd step：Workpiece after annealing is finished, key of arranging flowers；4th step：Spline housing after finishing is heat-treated；5th step：Workpiece after carbo-nitriding, carry out blasting treatment.This programme by mutually the running through of cold and hot working, combine, using the cold working of the high-precision lathe of NC postprocessing and gear shaping bed, with reference to the new heat processing technique of special carburizer, workpiece mechanical performance is increased dramatically, the mechanical performance indexs such as the fatigue strength of workpiece, wearability, yield strength are obviously improved compared with conventional machining process, effectively extend the service life of workpiece and complete machine engineering machinery, reduce maintenance cost and enterprise image and CSAT.
Description
Technical field
The present invention relates to a kind of processing technology of spline housing.Belong to technical field of engineering machinery.
Background technology
The chain junctor that spline housing is a high rotating speed, supported again, therefore its comprehensive mechanical performance is vital, bag
Include wearability, yield strength etc..In present spline housing production technology, most enterprises are still using artificial or artificial
The method for operating machinery, Technology for Heating Processing link is weak, and workpiece service life is not high, and so not only investment is high, also extremely expends
Manpower and materials, while spline housing quality can not be completely secured, the service life of workpiece is influenceed very big.
The content of the invention
To achieve the above object, present invention employs following technical scheme：
A kind of processing technology of spline housing, concrete technology step are as follows：
The first step：Blanking is carried out from the round steel that material is 20CrMnTi and forms blank, and blank is carried out by equipment
Roughing；
Second step：Workpiece after roughing carries out modifier treatment, and workpiece is to slowly warm up into 800 DEG C, kept for 3 hours, with
After annealed；
3rd step：Workpiece after annealing is finished, key of arranging flowers；
4th step：Spline housing after finishing is heat-treated, selected heat treatment method is carbo-nitriding, with stove
920 DEG C are warming up to, comes out of the stove and is quenched in organic solution.This method heat treat furnaces used therein is pit carburizing furnace, its specification chi
Very little is deep 3 meters, 0.5 meter of diameter；
5th step：Workpiece after carbo-nitriding, blasting treatment is carried out, selected blasting method is water sandblasting, water sandblasting
After apply special antirust agent, form finished product.
Beneficial effect of the present invention：Compared with prior art, the technical program by mutually the running through of cold and hot working, combine,
Using the cold working of the high-precision lathe of NC postprocessing and gear shaping bed, with reference to the new heat processing technique of special carburizer, workpiece mechanicalness
It can be increased dramatically, the mechanical performance index such as the fatigue strength of workpiece, wearability, yield strength shows compared with conventional machining process
Lifting is write, ensures quality, effectively extends the service life of workpiece and complete machine engineering machinery, reduces maintenance cost and enterprise shape
As and CSAT.
