Description
Technical field
It the utility model is related to sintering art, and in particular to a kind of efficient sintering press-powder instrument.
Background technology
As shown in figure 1, sintered body is manufactured using mould 1, such as during diamond roller, it is necessary first to add in mold cavity 2
Add metallurgical powder, then pressurizeed using forcing press 5 on press-powder instrument 3, press-powder instrument 3 is by the metallurgical powder pressure in mold cavity 2
It is real to form powder compact, high temperature sintering is finally carried out again.
It is correspondingly, right in graphite jig chamber 2 because roller center typically has mounting hole in sintered diamond roller
Position is answered to be provided with entity graphite chipware 9.Press-powder instrument 3 has cavity 4, and press-powder instrument 3 is enclosed on outside graphite chipware 6, and right
Metallurgical powder pressure in mold cavity 2.
From top to bottom diameter is identical for the cavity of existing press-powder instrument 3, excessive with the contact area of graphite chipware 9, is easily pressing
Be difficult to take out outward after entering, and strength take out can cause it is internal suppressed fixed powder and loosened again, metallurgical powder is risen
Less than the effect of completely densified.
In addition, the existing outer dia of press-powder instrument 3 is also from top to bottom identical, therefore the pressed powder of press-powder instrument 3 is big
Part power applies vertically downward, to the metallurgical powder lateral pressure deficiency around press-powder instrument 3, causes pressed powder closely knit
Degree deficiency.
Utility model content
The technical problems to be solved in the utility model is that existing press-powder instrument is pressed into after mold cavity it is difficult to take out, and suppress
The problem of side force deficiency.
The purpose of this utility model is to provide a kind of efficient sintering press-powder instrument, is easy to after chipware is pressed into past
Outer taking-up, inside will not be caused to have suppressed fixed powder and loosened again, and can be preferably to the smelting around press-powder instrument
Bronze end applies lateral pressure, and pressed powder compactness is more preferable.
A kind of efficient sintering press-powder instrument of the present utility model, for the powder pressure to sintering mold intracavitary, institute
It is the cylinder with cavity to state press-powder instrument, and press-powder tool cover presses outside the chipware in mold cavity to powder, the cylinder
The periphery of bottom preset height tilts towards column axis direction.
The cavity is from top to bottom divided into the first cavity and the second cavity, the shape and diameter of the second cavity respectively with it is described
The shape and diameter of chipware are engaged；The diameter of first cavity is more than the diameter of the second cavity, and the first cavity and the second cavity connect
The place of connecing forms ladder.
First cavity and the second cavity is cylindric or prism-shaped.
The press-powder upper tool part outer peripheral face has the boss radially extended along cylinder.
Relative to prior art, technique effect of the present utility model is efficient sintering press-powder work of the present utility model
, certain avoiding space between the first cavity and chipware be present so that press-powder instrument is easy to outward after chipware is pressed into tool
Take out, thus inside will not be caused to have suppressed fixed powder and loosened again.The periphery of press-powder tool bottom is towards column axis
Direction tilts, and preferably can apply lateral pressure to the metallurgical powder around press-powder instrument, increase pressure transmission efficiency, suppress powder
Last compactness is more preferable.

Fig. 2 is the structural representation of press-powder instrument of the present utility model；
Fig. 3 is the enlarged drawing of the part marked as a in Fig. 2；
Fig. 4 is partial schematic diagram of the press-powder tool cover of the present utility model on chipware.
Embodiment
As shown in Figures 2 to 4, the sintering press-powder instrument 3 of the present embodiment, for being applied to the powder of sintering mold intracavitary
Pressure, press-powder instrument 3 are the cylinder with cavity, and press-powder instrument 3 is enclosed on outside the chipware 9 in mold cavity to press to powder, cavity
From top to bottom be divided into the first cavity 41 and the second cavity 42, the shape and diameter of the second cavity 42 respectively with the shape of chipware 9 and
Diameter is engaged；The diameter of first cavity 41 is more than the diameter of the second cavity 42, the first cavity 41 and the junction of the second cavity 42
Ladder is formed, the first cavity 41 forms avoiding space A with chipware 9.
First cavity 41 and the second cavity 42 is cylindric or prism-shaped.When chipware 9 is cylindric, the He of the first cavity 41
Second cavity 42 is cylindric.When chipware 9 is prism-shaped, the first cavity 41 and the second cavity 42 are prism-shaped.
The upper periphery face of press-powder instrument 3 has the boss 6 radially extended along cylinder, using boss 6 as the point of application, convex
The bottom up percussion of platform, can take out press-powder instrument 3.
The periphery of cylinder bottom preset height tilts towards column axis direction, forms an inclined-plane 7.Due to press-powder instrument 3
Surrounding also has metallurgical powder, and the metallurgical powder around press-powder instrument 3 can only rely on the lateral pressure of press-powder instrument 3 be pressed
It is real, therefore set the inclined-plane 7 preferably can apply lateral pressure, pressure to the metallurgical powder around press-powder instrument 3 in cylinder bottom
Powder densification degree processed is more preferable.
In pressed powder process, because the diameter of the second cavity 42 is engaged with the diameter of chipware 9, on the one hand can farthest it press
The powder of the real periphery of chipware 9, on the other hand guiding function can be played to the stroke of press-powder instrument 3, to realize more preferable press-powder
Effect.
When press-powder terminates to need to take out press-powder instrument 3, using the boss 6 in the upper periphery face of press-powder instrument 3 as the point of application, to
Upper taking-up press-powder instrument 3.Due to having avoiding space, the cavity of press-powder instrument 3 and chipware 9 between the first cavity 41 and chipware 9
Contact area is reduced, and is equal to and is reduced contact friction, therefore press-powder instrument 3 is easy to take out from chipware 9, avoids strength
Taking-up causes inside to suppress the problem of fixed powder loosens again, and metallurgical powder has preferable consolidation effect.
To sum up, a kind of convenient sintering press-powder instrument taken out of the present utility model, the diameter of the first cavity are more than second
The diameter of cavity, certain avoiding space between the first cavity and chipware be present so that press-powder instrument after chipware is pressed into very
Easily take out outward, thus inside will not be caused to have suppressed fixed powder and loosened again.The periphery of press-powder tool bottom towards
Column axis direction tilts, and preferably can apply lateral pressure, increase pressure transmission effect to the metallurgical powder around press-powder instrument
Rate, pressed powder compactness are more preferable.
The above is only preferred embodiment of the present utility model, it is noted that for those skilled in the art,
Under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as this reality
With new protection domain.
