It is an object of the invention to provide one kind through into machining is no longer carried out after shape forging, not only increase only efficiency,
Save raw material and improve the net process into shape forging of engaging sleeve end tooth of the service life of engaging sleeve.
A kind of net process into shape forging of engaging sleeve end tooth, including end tooth upper die forming process and engaging sleeve end tooth
Disposable net shaping forging process:
Contour forming process comprises the following steps on described end tooth：A1, the engaging sleeve product figure provided according to client, are carried out
The 3-D Moulding Design of part, generates the part 3D solid of cold conditions, with reference to forging technology and the demand of process for machining outside
Profile and rear end face reserving machine add surplus；B1, the forged material for choosing forging, according to the linear expansion coefficient of the material and forging temperature
Degree, calculates the shrinkage factor of the forging at a temperature of needed for disposable net shaping forging technology；C1, the contraction with reference to forging
Rate, expands to cold conditions forging, generates hot entity forging, and by hot entity forging reincarnation into mould on hot end tooth reality
Figure modelling；D1, the solid modelling according to mould on the hot end tooth of generation, by programming, to mould on end tooth zero on CNC milling machine
Part first carries out rough milling end tooth, then mould part on end tooth is heat-treated, and finish-milling processing end tooth is carried out after heat treatment, extremely
This, completes the forming process of mould on hot end tooth.
Described disposable net shaping forging process comprises the following steps：A2, by mould on end tooth, cavity plate, push rod assembling, tight
It is fixed on forging equipment, according to mould program ver-ify upper and lower mould concentricity；After b2, verification meet the requirements, mould is preheated
Processing, 200 ° ~ 260 ° are preheated to by mould；C2, by the qualified bar of sawing be placed in Medium Frequency Induction Heating Furnace heat, be heated to
Temperature needed for forging, frequency, the loading frequency of Reasonable adjustment bar are forged according to the processing of forging equipment；D2, adjustment forging are set
Standby hitting power, the bar for being up to forging temperature is placed in cavity plate, starting device, and disposable strike is carried out to bar and is forged into
Shape；After the completion of e2, shaping, in forging equipment reseting procedure, start push rod, the hot forging of engaging sleeve is ejected into cavity plate, and profit
Manually or manipulator takes the hot forging of engaging sleeve away, the disposable net shaping forging process of engaging sleeve end tooth is so far completed.
Further, the material of described forging is 20CrMnTiH or 22CrMoH, described linear expansion coefficient for 14 ×
10-6, described forging temperature is 950~1000 degree, and described shrinkage factor is 1.0133~1.014.
The present invention is a kind of net process into shape forging of engaging sleeve end tooth, and its advantage is：
A kind of net process into shape forging of engaging sleeve end tooth of the present invention, improves engaging sleeve production efficiency, reduces the production
The production cost of product, particularly cutter are consumed, while improving the intensity of end tooth, the service life of overall lifting engaging sleeve reaches
The manufacture section material of engaging sleeve end tooth, efficient and destruction material less metallic fiber flow direction, and then the intensity of lifting end tooth is reached, it is whole
Body lifts the service life of engaging sleeve；Engaging sleeve end tooth it is net into shape forging, end tooth dense internal organization degree can be improved, change
End tooth metal streamline direction, improves the distribution of forging carbide, anisotropy is eliminated, in the hope of the inside required for acquisition
Tissue and performance.
