Description
Technical field
The utility model belongs to the precision forging field shaping technique of complex character part, is more particularly to a kind of universal joint
Portion precise molding die.
Background technology
Universal joint is the parts of prior varied angle power transmission, for needing to change the position for being driven axis direction.It is
" joint " part of the univesal wheelwork of automobile driving system.Product is symmetrical member, and required precision is high.In precise forming,
Because product characteristics are complicated, appearance profile degree requires high, for the mismatch amount of product, Wall-Thickness Difference, reference circle.In traditional design mould
During lamps structure, positioned using alignment pin, product design profile tolerance can ensure, but the weak point of this mould structure exists
In, it is impossible to ensure the uniformity of the reference circle of product.
Utility model content
The purpose of this utility model is to provide a kind of universal joint die finish for the reference circle uniformity for ensureing product and signed an undertaking
Structure.
According to one side of the present utility model, there is provided a kind of universal joint finishing mold structure, including upper bolster is with
Die holder,
The upper bolster includes Upper Die-sleeve, pressure block, drift set and punch holder, the pressure block and drift set assembling
In the Upper Die-sleeve, the pressure block is located at the top of drift set, and the Upper Die-sleeve is provided with the first cavity and the second chamber
Body, the shape of the first cavity are matched with the profile of the pressure block, and the pressure block is fastened in first cavity, described
The profile that the shape of second cavity covers with the drift is matched, and the drift set is fastened in second cavity, the punching
The 3rd cavity is provided with headgear, the shape of the 3rd cavity is matched with the profile of the punch holder, and the punch holder card is set
In the 3rd cavity, drift is fixed with the punch holder,
The die shoe offers the cavity plate being engaged with the drift.
Using Split mold structure, Split mold is positioned using cake position is cut, and ensures the uniqueness at positioning, solves
There is the problem of excessive mismatch amount, reference circle deviation in workpiece, ensure that in follow-up and connected part be not in deviation.
In some embodiments, in the fast center line of the center line of the Upper Die-sleeve, the pressure, drift set
Heart line is consistent with the center line of the punch holder.Thereby guarantee that the precision of mould.
In some embodiments, the drift is structure as a whole with the punch holder.Integrative-structure is easy to make and tied
It is real durable.
Brief description of the drawings
Fig. 1 is a kind of structural representation of universal joint finishing mold structure of the embodiment of the utility model one.
Embodiment
Fig. 1 schematically shows a kind of universal joint finishing mold of embodiment of the present utility model.As shown in figure 1,
The universal joint finishing mold includes upper bolster and die shoe.
Upper bolster includes Upper Die-sleeve 1, pressure block 2, drift set 3 and punch holder 4.Pressure block 2 and drift set 3 are assemblied in mould
In set 1.Pressure block 2 is located at the top of drift set 3.Upper Die-sleeve 1 is provided with the first cavity and the second cavity.The shape of first cavity with
The profile of pressure block 2 is matched, and pressure block 2 is fastened in the first cavity.The profile phase that 5 set 3 of the shape of second cavity and drift
It coincide, drift is fastened in the second cavity for 5 set 3.The 3rd cavity, shape and the punch holder 4 of the 3rd cavity are provided with drift set 3
Profile matches.Punch holder 4 is fastened in the 3rd cavity.Using Split mold structure, Split mold is determined using cake position is cut
Position, ensure the uniqueness at positioning, solve the problems, such as that workpiece occurs that mismatch amount is excessive, reference circle deviation, ensure that follow-up
And connected part is not in deviation.The fast center line of the center line of Upper Die-sleeve 1, pressure, the center line of drift set 3 and punching
The center line of headstock 4 is consistent.Thereby guarantee that the precision of mould.Drift 5 is fixed with punch holder 4.Drift 5 is with punch holder 4
Integrative-structure.Integrative-structure be easy to make and it is durable.Die shoe offers the cavity plate being engaged with drift 5.
Above-described is only some embodiments of the present utility model.For those of ordinary skill in the art, exist
On the premise of not departing from very utility model creation design, various modifications and improvements can be made, it is new that these belong to this practicality
The protection domain of type.
