Abstract
The utility model discloses a die for pressing a molybdenum slab. The die comprises a base. Two first slide blocks and two second slide blocks are symmetrically arranged on the base. The two sides of the base are respectively connected with a semi-circular side protecting sleeve. A hollow upper punching head is arranged above the first slide blocks and the second slide blocks. A cross rod is arranged in a cavity of the upper punching head. A round end cover is arranged above the upper punching head. The top of the end cover is connected with a handle. The die for the molybdenum slab solves the problem that external dimension of the slab prepared through the prior art is poor in precision. Moreover, the molybdenum slab manufactured in a pressing mode is high in density and uniform, molybdenum powder is not wasted in the pressing process, and the utilization efficiency of raw materials is high.
Description
Technical field
The utility model belongs to material Preparation equipment technical field, relates to a kind of compacting molybdenum plate base mould.
Background technology
The pressing mode of existing molybdenum plate base mainly contains two kinds, and a kind of is to adopt the 500t hydraulic press by the mechanical presses steel mold, makes the molybdenum powder in mould be shaped to standard-sized blank.The second is to adopt cold isostatic press by the mode of hydraulic pressure, and the glued membrane that molybdenum powder is equipped with in extruding obtains crude green body, then through finishing, reaches standard size.
The slab of hydraulic press compacting, although dimensional accuracy is high, raw material availability is high, but because the thickness of the general blank of restriction of equipment all is no more than 15mm, the substance maximum is only also 2kg, and the mode of its moulding is the single way stempressing moulding, and sotck thinkness can not be excessive, otherwise there will be green density inhomogeneous, fall the defects such as limit arrisdefect.
The slab of the quiet machine compacting such as cold, be by with rubber, making sheath material, according to Pascal's law, take liquid and be pressure medium, utilize goods in closed pressure vessel at each to impartial super-pressure pressure state compacted under.Use the slab of rubber package set material as the mould compacting, because die deformation is serious, cause the apparent size precision of slab poor, need to repair blank, and the utilization rate of raw material is low.
The utility model content
The purpose of this utility model is to provide a kind of compacting molybdenum plate base mould, has solved the poor problem of slab apparent size precision prepared by prior art.
The technical scheme that the utility model adopts is: compacting molybdenum plate base mould, comprise base, on base, be symmetrically arranged with two the first slide blocks and two the second slide blocks, the both sides of base are connected with respectively a semicircular side sheath, the top of the first slide block and the second slide block is provided with the upper punch of inner hollow, is provided with cross bar in the cavity of upper punch; The top of upper punch is provided with circular end cap, and the top of end cap is connected with handle.
Characteristics of the present utility model also are,
After two the first slide blocks and two the second slide blocks combine, rectangular enclosure of the common formation of its inwall.
The outer wall shape of the shape of the inwall of side sheath and the first slide block and the second slide block adapts.
One end of each side sheath is provided with a lug boss, and the other end is provided with a recess, and the shape of lug boss and the shape of recess adapt.
The beneficial effects of the utility model are: compacting molybdenum plate base of the present utility model is high by molybdenum plate base dimensional accuracy prepared by mould, and the high and uniformity of density is higher to the utilization rate of raw material.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model compacting molybdenum plate base with mould;
Fig. 2 is the structural representation after the utility model compacting molybdenum plate base completes with die assembly.
In figure, 1. base, 2. the first slide block, 3. the second slide block, 4. side sheath, 401. lug bosses, 402. recess, 5. upper punch, 6. cross bar, 7. end cap, 8. handle.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is elaborated.
Compacting molybdenum plate base of the present utility model with mould as shown in Figure 1, comprise base 1, on base 1, be symmetrically arranged with two the first slide blocks 2 and two the second slide blocks 3, the both sides of base 1 are connected with respectively a semicircular side sheath 4, the top of the first slide block 2 and the second slide block 3 is provided with the upper punch 5 of inner hollow, in the cavity of upper punch 5, is provided with cross bar 6; The top of upper punch 5 is provided with circular end cap 7, and the top of end cap 7 is connected with handle 8.
After two the first slide blocks 2 and two the second slide blocks 3 combine, rectangular enclosure of the common formation of its inwall.
The outer wall shape of the shape of the inwall of side sheath 4 and the first slide block 2 and the second slide block 3 adapts.
One end of each side sheath 4 is provided with a lug boss 401, and the other end is provided with a recess 402, and the shape of the shape of lug boss 401 and recess 402 adapts.
During work, first the first slide block 2 and the second slide block 3 are placed on base 1, then two side sheaths 4 are closed from two side direction intermediate sleeve of base 1, the corresponding fit of recess 402 of the lug boss 401 of a side sheath 4 and another side sheath 4, and the inner wall shape of the side sheath 4 of cover after getting togather is corresponding with the outer wall shape of the first slide block 2 and the second slide block 3; In the rectangular cavity that the first slide block 2 and the second slide block 3 form of now appropriate molybdenum powder being packed into, after installing, will hold again cross bar 6 upper punch 5 is aimed at and put into rectangular cavity and contact with molybdenum powder.The mold integral that finally will install molybdenum powder is put into cold isostatic press, under the effect of ambient pressure, two side sheaths 4 promote the first slide blocks 2 and the second slide block 3 pushes molybdenum powder from the side, and upper punch 5 and base 1 are from above-below direction extruding molybdenum powder, and molybdenum powder is pressed into the molybdenum plate base the most at last.
When mould is not used, after mould is assembled according to top duty, with end cap 7, cover in the upper end of side sheath 4, to avoid mold fouling.
By the way, compacting molybdenum plate base of the present utility model has solved the poor problem of slab apparent size precision prepared by prior art with mould, and the molybdenum plate base density be pressed into is high and uniformity, and in pressing process, molybdenum powder is without waste, higher to the utilization rate of raw material.
