Description
Technical field
The present invention relates to a kind of processing technology of insertion axle.
Background technology
Automobile insertion axle is one of important spare part in automobile variable speed mechanism, and insertion axle is due to high-speed driving to be mounted in
On bridge, rotating speed reaches 4000 revs/min, therefore it requires there is higher case hardness, less circumference bounce and center toughness, so
And typically now using induction hardening process or directly will be used as final heat treatment using quenched.Although impewdance matching quenching can be protected
The higher case hardness of card and centre hardness, but deformation more difficult control during quenching；Although quenched can efficiently control deformation, table
The hardness and anti-wear performance in face can not reach requirement.
The content of the invention
The invention provides a kind of processing technology of insertion axle, it makes the insertion axle processed have higher surface hard
Degree, high center toughness and the bounce of less circumference.
Present invention employs following technical scheme：A kind of processing technology of insertion axle, it comprises the following steps：Step one,
Forging：From low-carbon alloy Steel material, according to drawing requirement forging and molding；Step 2, normalized treatment：By the insertion axle after forging
In 920 DEG C of -930 DEG C of progress normalizings, harmful structure can be so refined, banded structure and Wei Shi bodies that forging is formed is eliminated, together
When improve hardness, improve cutting ability；Step 3, rough turn processing：By insertion axle is cylindrical and the rough turn processing of end face after it is preliminary
Shaping, unilateral reserved allowance 0.75-1mm, roughness reaches Ra6.3；Step 4, car overall length drill centers：Use milling flat
Drill centers lathe puts down the two ends spindle nose milling of insertion axle and drill centers；Step 5, the shaping of half smart car：By the cylindrical of insertion axle
According to the shaping of the smart car of technical requirements half, axle is cylindrical to stay 0.5mm surpluses；Step 6, it is with nothing left：Using the thimble clamping of numerically controlled lathe two,
Quickly 0.5mm surplus cars are fallen, while ensureing circumference bounce in 0.05mm once；Step 7, gear hobbing：Rolled out using gear-hobbing machine
One end spline of insertion axle；Step 8, gear shaping：Go out the other end spline of insertion axle using the gear shaping machine transplanting of rice；Step 9, carburizing and quenching
Processing：Insertion axle is vertically loaded into by progress carburizing and quenching processing in stove using fixture, carburizing medium uses nitrogen and methanol atmosphere, third
Ketone is enriched gas, and quenching liquid is using G oil；Step 10, cylindrical grinding：The bearing fit section for needing the insertion axle coordinated is carried out cylindrical
Grinding forming processing, the bearing section for the insertion axle that need not coordinate will also be carried out grinding and ensure bounce in below 0.02mm.
Low-carbon alloy Steel material is 20CrMnTi low-carbon alloy Steel materials in step one of the present invention.In step 2 of the present invention just
The temperature of fire is 920 DEG C -930 DEG C.The mm of allowance 0.75,0.8 mm or 1mm are reserved in side in step 2 of the present invention.
The invention has the advantages that：Employ after above technical scheme, the insertion axle of invention plus
Work technique, the method that smart car is improved in existing conventional machining process, first half smart car stays 0.5mm surpluses, is protected in a knife with nothing left
Demonstrate,prove circumference bounce below 0.05mm；Carburizing and quenching has been used in heat treatment instead, case hardness and center portion intensity has been heightened, in cylindrical grinding
Not only want grinding bearing to coordinate section, also to ensure below the 0.02mm that beats to mismatching section and be ground, it is so high in insertion axle
It will not also be beated during speed operating or eccentric.
