Description
Technical field
This utility model relates to a kind of mould utilizing PM technique compacting bronze structures part.
Background technology
Bronze is the great invention of in human history, and the application of bronze powder metallurgy is also in iron-based powder smelting
Before gold, but bronze powder metallurgy is for making the most little of structural member, iron-based powder at present
The comparison that metallurgy occupies is many, because in addition to the reason of the aspects such as material cost, suppresses with bronze powder metallurgy
Still there are some problems in structural member, to using the bronze machinery zero requiring cannot to substitute with iron based compacts
Part, has two big subject matters；First bronze powder metallurgy pressed density is low, and the mechanical strength of part does not reaches
Use requirement.Second bronze powder is metallurgical to be changed very when sintering, and dimensional accuracy can not meet use requirement.
Utility model content
In order to solve problem present in background technology, this utility model provides the powder of a kind of bronze structures part
The metallurgical molding finishing mold in end, this mould can produce intensity and precision bronze structures part the most up to standard.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
The powder metallurgy forming finishing mold of a kind of bronze structures part, including press portion and moulding section, pressure
Part processed is arranged on moulding section top, it is characterised in that moulding section includes shaping former, shaping former
Middle part be provided with medium altitude groove, the bottom of medium altitude groove is provided with shaping undershoot, the bias one of shaping undershoot
Side arranges perforation, and perforation middle and upper part is provided with shaping core rod, and bottom is provided with plug extension bar, and shaping core rod is
Hollow, fixing bolt passes the hollow bulb of plug and is fixed on the top of plug extension bar by adjusting pulvinulus；
Press portion includes bonding press, and the bottom of bonding press is fixed with shaping upper punch by upper press cover, whole
The profile of shape upper punch and medium altitude groove external shape fits, shaping rushes to eccentric setting shaping core rod passage, whole
Core rod passage is corresponding with shaping core rod.
The upper end of described shaping core rod is provided with stage portion, and the diameter of stage portion top shaping core rod is less than step
The diameter of subordinate portion shaping core rod.
Shaping undershoot is fixed on undershoot pressure pad, and undershoot pressure pad is fixed on board.
The beneficial effects of the utility model are: custom-designed powder metallurgy die, and this mould can be suppressed
Go out intensity and precision bronze structures part the most up to standard.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated
Fig. 1 is the assembling structural representation of powder metallurgy forming finishing mold described in the utility model；
Detailed description of the invention
This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings:
Embodiment 1
As it is shown in figure 1, the powder metallurgy forming finishing mold of a kind of bronze structures part, including press portion and
Moulding section, press portion is arranged on moulding section top, and moulding section includes shaping former 5, shaping former
The middle part of 5 is provided with medium altitude groove 6, is used for filling bronze powder, the end of medium altitude groove 6 in medium altitude groove 6
Portion is provided with shaping undershoot 9, and the eccentric side of shaping undershoot 9 arranges perforation, and perforation middle and upper part is provided with shaping
Plug 8, bottom is provided with plug extension bar 11, and shaping core rod 8 is hollow, and fixing bolt 7 is through plug
Hollow bulb is also fixed on the top of plug extension bar 11 by adjusting pulvinulus 10.The upper end of shaping core rod 8 is arranged
Having stage portion 14, the shaping core rod diameter on stage portion 14 top is straight less than the shaping core rod of stage portion 14 bottom
Footpath.Shaping undershoot 9 is fixed on undershoot pressure pad 13, and undershoot pressure pad 13 is fixed on board 12.
Press portion includes bonding press 1, and the bottom of bonding press 1 is fixed with shaping upper punch by upper press cover 2
3, the profile of shaping upper punch 3 and medium altitude groove 6 external shape fits, in shaping upper punch 3, eccentric setting has shaping core
Rod passage 4, shaping core rod passage 4 is corresponding with shaping core rod 8.
The present invention it is critical only that shaping core rod is provided below adjustment pulvinulus, by changing or plain grinding pulvinulus, with
Adjust the shaping degree of depth.By such totally-enclosed finishing shape, not only protect whole endoporus and stably reached in 4 grades
The requirement of hole precision, is also greatly improved density.
It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, permissible
Above-mentioned embodiment is carried out various amendment, changes and combine, and think this amendment, change and combine
Within the scope of originality thought.
