Description
Technical field
The present invention relates to mold design technical field, more particularly to a kind of one or two grades of hot schools of shift fork
Holotype.
Background technology
Some auxiliary components being commonly used in the vehicles and plant equipment, more than its shape less
Rule, shift fork is exactly common one kind in this kind of part, and the traditional diamond-making technique of these parts is more
It is casting, the processing efficiency and precision of the processing method are all very low, and easily cause traffic
Damage of other strength members etc. in instrument and plant equipment, these parts can also be using forging
Method is processed, and former forging die is unreasonable due to structure design, and mould strength is low, and precision is low,
The service life of driving parts, high cost are influenceed, therefore a kind of security of design is good, mould base
Body hardness is high, and intensity is big, upper die and lower die accurate positioning, the 1 of the blocking high precision of part
Shelves shift fork thermal recalibration mould seems very necessary.
The content of the invention
The purpose of the present invention is exactly to overcome prior art to process shift fork complex process, efficiency
Low, the low defect of precision devises a kind of one or two grades of shift fork thermal recalibration moulds, and security is good, on
Mould and lower mould are fixed conveniently, the thermal recalibration high precision of part, upper model groove and drag groove it is curved
Qu Chengdu is big, and one or two grades of shift forks are placed between upper die and lower die and carry out thermal recalibration and add at high temperature
Work, forming efficiency is high.
The required technical problem for solving of the invention can be achieved through the following technical solutions：
A kind of one or two grades of shift fork thermal recalibration moulds, upper die and lower die, the upper mould and the lower mould
Matrix is a cuboid, also including upper model groove, drag groove, fixing lug boss, it is described on
Model groove is located at the lower surface of the upper mould, and the drag groove is located at the upper table of the lower mould
Face, the upper model groove and the drag groove are symmetrical arranged before and after being, the fixing lug boss
It is arranged on front and rear each one on the symmetrical line in upper surface of the lower mould, mould is right on described
Position is answered to be provided with fixed counterbore.
The equal chamfering of all sharp edges of the upper mould and the lower mould is into 1 × 45 ° of root face.
Cylindrical hole is machined with the counterbore of the fixing lug boss of the lower mould and the upper mould.
The surface roughness of the upper model groove and the drag groove is controlled within 0.8mm.
The degree of crook of the upper model groove and the drag groove is big.
As a result of above technical scheme, the invention has the advantages that：
Mutually tied using upper die and lower die, shift fork root type groove, shifting fork bar type groove, group plug type groove
Close one or two grades of designed shift fork thermal recalibration moulds, the equal chamfering of all sharp edges of upper die and lower die into
1 × 45 ° of root face, does not easily cause personal injury during work, security is good, lower mould fixing lug boss and
Cylindrical hole is machined with the counterbore of upper mould, it is solid using connector connection during upper die and lower die matched moulds
It is fixed, be fixed conveniently, the surface roughness control of upper model groove and drag groove 0.8mm with
Interior, the thermal recalibration high precision of part, the degree of crook of upper model groove and drag groove is big, and one or two
Shelves shift fork carries out thermal recalibration processing between being placed in upper die and lower die at high temperature, and forming efficiency is high.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to
Understand and understand, with reference to being specifically illustrating, the present invention is expanded on further.
A kind of one or two grades of shift fork thermal recalibration moulds, including upper mould 1, lower mould 2, upper model groove 3,
The matrix of drag groove 4, fixing lug boss 5, upper mould 1 and lower mould 2 is a cuboid, on
Model groove 3 is located at the lower surface of upper mould 1, and drag groove 4 is located at the upper surface of lower mould 2, on
Model groove 3 and drag groove 4 are symmetrical arranged before and after being, and fixing lug boss 5 is arranged on lower mould 2
The symmetrical line in upper surface on front and rear each one, the correspondence position of upper mould 1 is provided with fixation
Counterbore (is not drawn into) in figure, fixing lug boss 5 and counterbore (figure when upper mould 1 and lower mould 2-in-1 mould
In be not drawn into) embedded install, you can conveniently realize to one or two grades of thermal recalibrations processing of shift fork,
