Abstract
The utility model provides a cold isostatic pressing forming mold used to produce the sintered powder filter tube, which mainly consists of a positioning base, a mandrel, perforated steel sets, a lengthened screw sleeve and positioning powder devices. The mould is characterized in that the bottom of steel sleeve is fixed on the base in position; a positioning device for the powder is designed in the form of a concentric ring, the inner ring hole assorts with the top of the mandrel, and the outer wall is provided with screw thread and fits with the lengthened screw sleeve with outer thread. Practical use of the device adopts the upper and lower, inside and outside rigid cooperation, gives the guarantee to the uniform thickness of ring gap with powder, and keeps concentric and vertical with the inside and outside surface of the pressing billet. The mold positioning equipment for powder has evenly distributed holes and a larger number of the metal meshes, which can be kept rotation when the powder is loaded, to ensure uniform powder to fall on the ground floor around the ring and make the powder uniform.
Description
Technical field
The utility model relates to a kind of powder metallurgy cold isostatic compaction mould, particularly relates to a kind of cold isostatic compaction mould of the powder porous screen pipe pressed compact that is shaped.
Background technology
At present, elongated sintering metal powder filters the moulding of pipe and adopts the powder metallurgy cold isostatic compaction mostly, and the mould that is adopted is made up of plug, perforated metal cover, rubber sleeve and sealing plug.Use centering ring to ensure that wall thickness is all even concentric up and down.Because centering ring is by the external diameter of plug and rubber sleeve internal diameter location, the big precision in gap is very poor, and is easy to press from both sides powder and causes and slough the thimble difficulty; The length that adds centering ring is very short, and chimney filter bottom and top concentricity are relatively poor during the bigger filtration pipe of compacting length.Adopt the sintering metal powder filtration pipe of this mould and centering ring moulding often will determine the level and smooth of wall thickness and outer surface, so just increased operation and production cost through the Vehicle Processing outer wall.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of cold isostatic compaction mould of suppressing concentricity height, the uniform tubulose sintered powder of wall thickness screen pipe pressed compact is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of cold isostatic compaction mould of producing the sintered powder screen pipe, mainly by positioning base 8, plug 3, perforation steel bushing 6, lengthening swivel nut 2 and location powder filling device 1 are formed, it is characterized in that described plug 3, the lower end of perforation steel bushing 6 is fixed on the positioning base 8, lengthening swivel nut 2 is spun on perforation steel bushing 6 upper ends, and location powder filling device 1 is an annular concentric, annular distance is connected with plug 3 upper ends in it, and its outer shroud inwall is connected with lengthening swivel nut 2 upper end outer wall threads, and it is even to form thickness, the annular dress powder gap that the pressed compact surfaces externally and internally is concentric with vertical.
The utility model compared with prior art has the following advantages: the utility model reasonable in design, utilize the tubulose powder compact wall thickness of the utility model mould compression moulding even, inner and outer pipes is concentric, outer surface smoother, the sintered powder of compacting filters pipe does not need to carry out follow-up Vehicle Processing, and cost reduces.

The specific embodiment
Figure 1 shows that whole assembling schematic diagram of the present utility model, its part comprises location powder filling device 1, lengthening swivel nut 2, plug 3, rubber sleeve 4, perforation steel bushing 6, rubber stopper 7, positioning base 8, constitutes dress powder cavity 5 thus.The lower end of described plug 3, perforation steel bushing 6 is fixed on the positioning base 8, lengthening swivel nut 2 is spun on perforation steel bushing 6 upper ends, and location powder filling device 1 is an annular concentric, annular distance is connected with plug 3 upper ends in it, and its outer shroud inwall is connected with lengthening swivel nut 2 upper end outer wall threads, forms the annular dress powder gap that thickness is even, the pressed compact surfaces externally and internally is concentric with vertical.Described perforation steel bushing 6 inboards are equipped with rubber sleeve 4; Inboard, described rubber sleeve 4 lower end is provided with rubber stopper 7.Insert in the positioning base 8 after a while at the end, lower end that rubber stopper 4 is enclosed within plug 3 before the dress powder, subsequently with rubber sleeve 4 and perforation steel bushing 6 together (the two should be pre-assembled) pack into from plug 3 upper ends and be positioned on the positioning base 8, the swivel nut 2 that will extend again is spun on perforation steel bushing 6 upper ends, puts location powder filling device 1 at last.During the dress powder, metal dust shakes from the powder filling device 1 of location and falls into dress powder cavity 5.The height of location powder filling device 1 can be regulated by the length of rubber sleeve 4.
Fig. 2 is the assembling schematic diagram after cold isostatic compaction mould dress powder is finished.After the dress powder is finished, fill metal dust 10 in the dress powder cavity 5, take off location powder filling device 1 and lengthening swivel nut 2, rubber stopper 9 is filled in mould top, adopt fastening piece 11 to tighten, take off positioning base 8 subsequently, tighten the mould bottom.
Fig. 3 is the schematic diagram of location powder filling device 1 among Fig. 1.Be provided with equally distributed three holes 12 and metallic sieve 13 in the powder filling device of described location, be convenient to powder and fall into dress powder cavity 5.The hole at center cooperates with plug 3 upper end pillars, and annular outer wall cooperates with lengthening swivel nut 2 inwalls.
Fig. 4 is the partial enlarged drawing at A place among Fig. 1.Lengthening swivel nut 2 and perforation steel bushing 6 are by thread connection.
