Description
Technical field
The utility model belongs to forging mold technical field, specifically a kind of hammering for processing vehicle transmission forging shaft
Mould.
Background technology
Slip shaft yoke and slide fork forgings be transmission shaft important part, transmission forging shaft by hammer forging technique manufacture and
Into pulling technique plays a very important ring, drawing impression in the forging process of slip shaft yoke and slip fork forgings
It is the cross-sectional area for reducing blank part, increases its length, has the function that to distribute metal, be easy to the blank after pulling
Full of cavity；Slip shaft yoke and slip yoke class product belong to the elongated product of the wide bar portion of fork, in order to meet the shaping needs of fork
The selection blank bigger than bar portion sectional area, the pulling effect of bar portion blank directly influence blank and are full of feelings in mold cavity
The stock utilization of condition and forging, the efficiency of pulling can also directly affect the production efficiency of the entire production line.For these problems,
Design a kind of hammer forging die for processing vehicle transmission forging shaft there is an urgent need for us solve existing hammer forging die hammering often, efficiency it is low etc.
Problem.
Utility model content
In order to solve the above technical problems, the utility model provides, a kind of pulling number is few, and raising production efficiency, reduces worker
The hammer forging die of the processing vehicle transmission forging shaft of labor intensity.
The utility model is that technical solution is used by solving above-mentioned technical problem：A kind of hammer for processing vehicle transmission forging shaft
Forging die, includes the upper die and lower die of upper and lower pairing, and the face that upper die and lower die are involutory is hammering face, the hammering face phase of the lower die
To be provided at both ends with locating slot, the hammering face of the upper mold is provided with the locating piece of insertion locating slot, the upper die and lower die
Symmetrical groove is set respectively on hammering face, and formed respectively after upper die and lower die molding pulling cavity, blocking cavity and
Finish-forging cavity, the pulling cavity include hammering portion and accommodate the receiving portion of one end deformation after forging is hammered, the hammering portion
Thickness be less than the thickness of receiving portion, hammering portion is connected with receiving portion by 30 ° of sloping platform rounded corner transition, hammering portion end
Opening, stretches into pulling cavity to be forged for fixture clamping blank, flash gutters is equipped with around the finish-forging cavity.
Further improving as a kind of hammer forging die for processing vehicle transmission forging shaft of the utility model：The pulling cavity is located at
The side of upper die and lower die, and the side for pulling out cavity is open state.
Further improving as a kind of hammer forging die for processing vehicle transmission forging shaft of the utility model：The bottom of the lower die is set
It is equipped with for fixed dovetails.
Beneficial effect
A kind of hammer forging die for processing vehicle transmission forging shaft of the utility model, the utility model is by varying pulling compared with prior art
Cavity hammering size, reduces pulling number, improves production efficiency, and hammering portion is connected with receiving portion by 30 ° of sloping platform rounded corner transition
Connect, worker's back-and-forth motion blank in pulling, which need not raise blank end, can easily be moved rearwards blank, effectively
Reduce the labor intensity of worker；The utility model is reasonable in design simple and direct, efficiently solves transmission forging shaft and is pulled out in hammering
When, pulling hammering often, difficult shaping the problem of, improve stock utilization and production efficiency.
