Abstract
The invention discloses a kind of irregularly-shaped hole helical gear one-time forming dies, include an outside upper punching, upper punching in one is equipped in outside upper punching, the mold also includes mould in one, middle mould is equipped with a helical gear green compact, the mold also includes an outer undershoot, undershoot in one is equipped in outer undershoot, a plug is equipped in the outer undershoot and interior undershoot, the interior Shang Chong and interior undershoot are circle, the interior upper punching, interior undershoot and plug maintain static dynamic together, a kind of irregularly-shaped hole helical gear one-time forming die of the invention is by designing circular interior punching, and it is fixed on mould bases and does not rotate, only outside upper undershoot rotation when forming, Special Plug then maintains static together with interior upper undershoot dynamic, to realize that irregularly-shaped inner hole aligns, the once-forming helical gear powder metallurgy compact with irregularly-shaped inner hole out, reduce subsequent grinding program, reduce manufacturing cost , there is significant economic benefit.
Description
Technical field
The present invention relates to a kind of molds, more precisely, being a kind of irregularly-shaped hole helical gear one-time forming die.
Background technique
For the helical gear mold of irregularly-shaped inner hole, upper punching is generally designed to solid or circular hole at present, plug upper section is round,
Lower section abnormity.Helical gear compact inner holes after then shaping by this design are that blind hole or upper section circular hole, green compact need higher than finished product
0.2MM or so, then by grinding at final finished, manufacturing cost is higher.
Summary of the invention
The present invention mainly solves technical problem present in the prior art, to provide a kind of irregularly-shaped hole helical gear one
Secondary shaping dies.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:
A kind of irregularly-shaped hole helical gear one-time forming die includes an outside upper punching, and upper punching, the mould in one are equipped in outside upper punching
Tool also includes mould in one, and middle mould is equipped with a helical gear green compact, which also includes an outer undershoot, under being equipped in one in outer undershoot
A plug is equipped in punching, the outer undershoot and interior undershoot.
As preferred embodiments of the present invention, the interior Shang Chong and interior undershoot are circle.
As preferred embodiments of the present invention, the interior Shang Chong, interior undershoot and plug maintain static dynamic together.
A kind of irregularly-shaped hole helical gear one-time forming die of the invention is fixed on mould bases by designing circular interior punching
On do not rotate, only outside upper undershoot rotation when forming, Special Plug then maintained static together with interior upper undershoot it is dynamic, to realize abnormity
Inner hole contraposition, the once-forming helical gear powder metallurgy compact with irregularly-shaped inner hole out, reduces subsequent grinding program, drops
Low manufacturing cost has significant economic benefit.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of irregularly-shaped hole helical gear one-time forming die of the invention.
Specific embodiment
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1, a kind of irregularly-shaped hole helical gear one-time forming die 10, outside upper to rush in 20 comprising an outside upper punching 20
Equipped with punching 30 upper in one, which also includes mould 40 in one, and middle mould 40 is equipped with a helical gear green compact 80, which also includes one
Outer undershoot 50, outer undershoot 50 is interior to be equipped with undershoot 60 in one, is equipped with a plug 70 in the outer undershoot 50 and interior undershoot 60.
As to further improvement of the present invention, the interior upper punching 30 and interior undershoot 60 are circle.
As to further improvement of the present invention, interior upper punching 30, interior undershoot 60 and the plug 70 are fixed not together
Rotation.
A kind of irregularly-shaped hole helical gear one-time forming die of the invention is fixed on mould bases by designing circular interior punching
On do not rotate, only outside upper undershoot rotation when forming, Special Plug then maintained static together with interior upper undershoot it is dynamic, to realize abnormity
Inner hole contraposition, the once-forming helical gear powder metallurgy compact with irregularly-shaped inner hole out, reduces subsequent grinding program, drops
Low manufacturing cost has significant economic benefit.
Only illustrate mentality of designing of the invention in one embodiment above, in the case where system allows, this hair
It is bright to be extended to while external more functional modules, to extend its function to greatest extent.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
