Abstract
The present invention discloses a kind of blade and squeezes bar mould, including drift, recipient, extrude insert, guide pin bushing and push rod, recipient is provided with through hole vertically, through hole includes the first positioning hole being connected from the bottom to top, second positioning hole, endoporus, the radius of first positioning hole is more than the radius of the second positioning hole, the radius of second positioning hole is more than the radius of endoporus, the lower end of extruding insert is provided with the positioning boss being engaged with the first positioning hole, extrude upper end and the second positioning hole interference fits of insert, and the upper surface of extruding insert is acted against on the transition face between the second positioning hole and endoporus.The present invention in extruding insert lower end by setting positioning boss, make its registration, stably, and the oral area of extruding insert is designed to the end face structure that the transition face between the second positioning hole, endoporus is engaged, so that the oral area of extruding insert is not easy to wear, the service life of extruding insert is substantially increased, reduces maintenance cost.
Description
Technical field
The present invention relates to a kind of mould, more particularly to a kind of blade to squeeze bar mould.
Background technology
Blade squeezes a kind of mould that bar mould is the crowded bar of progress blade during Blade precision forging, and it is typically by drift, extruding
Cylinder, extruding insert, guide pin bushing and push rod composition.As shown in figure 1, bar mould recipient is squeezed with extruding the cooperation of insert for existing blade
Structural representation；The blade of such a structure squeezes bar mould, and it is sharp side that it, which extrudes the oral area of insert upper end, and it easily wears, and uses
Life-span is shorter, using soon just needing to change, greatly reduces blade and squeezes the efficiency of bar, and increases maintenance cost, thus,
It is badly in need of solving.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, providing a kind of blade squeezes bar mould, to solve the crowded bar of existing blade
The extruding insert of mould is easily worn, and service life is short, and maintenance cost is high, reduces the problem of blade squeezes bar efficiency.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of blade squeezes bar mould, including drift, recipient, extruding insert, guide pin bushing and push rod, and the recipient is vertically
Through hole is provided with, the through hole includes the first positioning hole, the second positioning hole, the endoporus being connected from the bottom to top, first positioning
The radius in hole is more than the radius of the second positioning hole, and the radius of second positioning hole is more than the radius of endoporus, the extruding insert
Lower end be provided with the positioning boss being engaged with the first positioning hole, extrude the upper end of insert and the second positioning hole interference fits,
And the upper surface of extruding insert is acted against on the transition face between the second positioning hole and endoporus.
As a preferred embodiment of the present invention, the drift is locked by upper latch segment.
As a preferred embodiment of the present invention, the recipient is locked by lower latch segment.
As a preferred embodiment of the present invention, the positioning boss of the extruding insert and the first positioning interporal lacuna coordinate.
Beneficial effects of the present invention are that a kind of blade squeezes bar mould by setting convex in extruding insert lower end
Platform, make its registration, stably, and the oral area for extruding insert is designed to that the transition face between the second positioning hole, endoporus matches
The end face structure of conjunction, so that the oral area of extruding insert is not easy to wear, the service life of extruding insert is substantially increased, is reduced
Maintenance cost, reduces maintenance times, improves blade and squeezes bar efficiency.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.It is appreciated that
It is that embodiment described herein is used only for explaining the present invention, rather than limitation of the invention.
It refer to shown in Fig. 2 and Fig. 3, Fig. 2 is the structural representation that a kind of blade of the present invention squeezes bar mould；Fig. 3 is this hair
Bright recipient and the fit structure schematic diagram of extruding insert.
In the present embodiment, a kind of blade squeezes bar mould, including drift 1, recipient 3, extruding insert 4, guide pin bushing 6 and push rod
7, the drift 1 is locked by upper latch segment 2, and the recipient 3 is locked by lower latch segment 5, and recipient 3 is along axle
To being provided with through hole, the through hole includes the first positioning hole, the second positioning hole, the endoporus 31 being connected from the bottom to top, and described first
The radius of positioning hole is more than the radius of the second positioning hole, and the radius of second positioning hole is more than the radius of endoporus 31, described to squeeze
The lower end of pressure insert 4 is provided with the positioning boss 41 being engaged with the first positioning hole, the positioning hole of positioning boss 41 and first
Gap coordinates, upper end and the second positioning hole interference fits of the extruding insert 4, and the upper surface for extruding insert 4 acts against the
On transition face 32 between two positioning holes and endoporus 31.
Above-mentioned blade squeezes bar mould, and it extrudes the oral area of the upper end of insert 4 and is designed to end face structure, with the second positioning hole, interior
Transition face 32 between hole 31 is engaged, and not only increases positioning precision, and can extend its service life, simple in construction, easy
In realization.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and modifications all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
