Technical field
The utility model relates to a kind of arcuate member powder cold pressing forming mould.
Background technology
Powder moulding mold is meant by powder is suppressed, so that it forms predetermined shape.The structure of present powder forming mould all is to go up low punch to stretch into simultaneously in the die cavity mouth of former, and forming belt is big apart from the distance of die cavity mouth, and knockout press is big, and die wear is serious.And during the compacting arcuate member, take along the compacting of arcwall face axis direction, for the less part of thickness, because the narrow charging difficulty of die cavity, easy formation lacks material, produces waste product, so is difficult to realize automatic charge.
The utility model content
At defective that exists in the prior art and deficiency, the purpose of this utility model is to propose a kind of arcuate member powder cold pressing forming mould that can improve die life.
In order to achieve the above object, the utility model proposes a kind of arcuate member powder cold pressing forming mould, comprise frame, and be fixed on bed die and former on the described frame, described former comprises that the former body reaches the through hole through described former body, described bed die is provided with a bed die protuberance, and the top of described bed die protuberance is the arc of epirelief; Suitable so that the described bed die protuberance of described bed die protuberance shape and described shape of through holes can stretch in the described through hole and with the wall sealing of through hole; Also comprise on setting and the described frame and the mold that can vertically move, described mold has a mold protuberance, the bottom of described mold protuberance has the camber line of an indent, and described bed die protuberance shape and described shape of through holes are suitable; The via top of described former body has and the suitable last convex of described mold protuberance bottom indent camber line.
Preferred as technique scheme, described former is fixed on the former base, and described former base is fixed on the base by fixing spring.
Preferred as technique scheme, described former is fixed on the former base, is provided with spring between described former base and the described bed die.
Preferred as technique scheme, described frame also comprises feeding unit, described feeding unit is fixed on the described frame and can moves along described frame; Described feeding unit bottom is provided with discharging opening, and described discharging opening is provided with and the suitable arc-shaped recess of the via top of described former body.
Preferred as technique scheme, described feeding unit comprises feeding mouth.
Preferred as technique scheme, described frame surface is provided with track, described feeding unit be provided with the suitable roller of track to move along described track.
The utility model proposes a kind of arcuate member powder cold pressing forming mould, have former, mold, bed die.Former has through hole, and via top has and the suitable camber line of mold protuberance the camber line that bed die protuberance top has epirelief.So in use, mold moved down so that the overlapping and sealing of the arc-shaped recess of mold bottom, make then and move on the bed die and make in the through hole of bed die protuberance insertion former with the arc convex of former via top.By the bed die pressurization, just powder compaction can be become the upper and lower arcuate member that all has predetermined arc like this.This structure can reduce the wearing and tearing to mould, improves the life-span of mould.The utility model can also increase a feeding unit simultaneously, can realize automatically transporting materials.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model preferred embodiment comprises frame 1 and is fixed on bed die 9 and former 10 on the described frame 1 as shown in Figure 1.As shown in Figure 1, former 10 is by on former base 4, and former base 4 is connected with base 1 by spring 3.Can cushion the downforce of mold so effectively, prevent because the excessive mould that causes of downforce damages.Equally, also be provided with spring 11 between the base 3.2 of this former base 4 and bed die 9.
As shown in Figure 4, described former 10 comprises that the former body reaches the through hole 4.2 through described former body.As shown in Figure 3, described bed die 9 is provided with a bed die protuberance 3.1, and the top of described bed die protuberance 3.1 is the arc of epirelief; Suitable so that the described bed die protuberance 3.1 of described bed die protuberance 3.1 shapes and described through hole 4.2 shapes can stretch in the described through hole 4.2 and with the wall sealing of through hole 4.2.As shown in Figure 3, bed die 9 can comprise a bed die base 3.2, and bed die protuberance 3.1 is fixed on the bed die base 3.2 by set bolt 3.3.
As shown in Figure 1, also comprise on setting and the described frame 1 and the mold 7 that can vertically move, described mold has a mold protuberance, as shown in Figure 5, the bottom of described mold protuberance has the camber line 5.1 of an indent, and described bed die protuberance shape and described shape of through holes are suitable; The via top of described former body has the last convex 4.1 suitable with described mold protuberance bottom indent camber line 5.1.Like this when mold 9 moves down, touch former 10, mold protuberance bottom indent camber line 5.1 is stuck on the convex 4.1, the top of through hole 4.2 that so just can airtight former, as described in Figure 2, form one in conjunction with bed die protuberance 3.1 again and hold material space 8.
As Fig. 1 and shown in Figure 6, described frame 1 also comprises feeding unit 6, and institute's feeding unit 6 is fixed on the described frame 1 and can moves along described frame 1; Described feeding unit bottom is provided with discharging opening, and described discharging opening is provided with the arc-shaped recess 6.1 suitable with the via top of described former body.When feeding unit 6 moved to through hole 4.2 tops of former 10, the last convex 4.1 fitted seal through holes 4.2 of this arc-shaped recess 6.1 and former 10 through holes 4.2 were to fail material like this.As shown in Figure 6, described feeding unit comprises feeding mouth 6.2.As shown in Figure 1, described frame 1 surface is provided with track 5, and described feeding unit 6 connects roller to move along described track 5 by fixed head 6.3.As shown in Figure 1, also comprise cam lifting mechanism 2, be used to drive bed die and move.
In use, its process comprises shown in Fig. 8 a-Fig. 8 f:
Shown in Fig. 8 a, each mechanism is in initial position, and the bed die protuberance is stretched in the through hole.Shown in Fig. 8 b, at first feeding unit 6 translations so that discharging opening overlaps with the through hole of former, and are failed material.As Fig. 8 c, after defeated material finished, feeding unit 6 was removed.As Fig. 8 d, this moment, bed die moved down, and the bottom of bed die protuberance is overlapped with via top.Shown in Fig. 8 e, bed die extruding powder, and drive former base 4 and move down, because the bottom surface, top of bed die protuberance has arc-shaped recess, and via top has last convex 4.1, can make the bottom of bed die protuberance and through hole airtight fully; And the top of bed die protuberance has the arc of epirelief, so just can be pressed into an arcuate member as shown in Figure 7.Shown in Fig. 8 f, cam lifting mechanism 2 is driven on the bed die move, finished product is made.Then under the effect of spring 11, the bed die return.
Certainly; the utility model also can have other embodiment; under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
