Description
Technical field
The utility model relates to a kind of extrusion die, especially a kind of stephanoporate thin wall aluminium-alloy pipe hot-extrusion mold of degree of precision.
Background technology
Coaxial stephanoporate thin wall aluminium-alloy pipe is widely used in the industries such as automobile, electric power, household electrical appliances at present.Its Main Function is by coaxial aperture, to shunt the object of the different fluids that require.And produce the type aluminium-alloy pipe in batches by the mode of hot extrusion, to reach efficient heat exchange be that current production efficiency is higher, the good mode of quality stability.Can required mould be guarantee normal key point of producing, and the processing of patrix core is the key point of the type Design of Dies, processing.It is that the whole processing of patrix is (as Fig. 1 that current existing the type aluminum pipe is prepared mould, shown in Fig. 2, 1a is patrix, 2a is counterdie, 3a is lower die model core, patrix 1a and patrix core are overall structure), the core rod preparation work of existing the type aluminum pipe mould mainly comprises: blank is opened slightly, wire hole, line cutting shape chamber, heat treatment, finish turning inside and outside circle, electric spark side is done manual work and is with, electric spark forehand reinforcement, leading flank mill metamorphic layer, leading flank polishing, main shortcoming and technology barrier are repeatedly to utilize electric spark to repeat processing, operation is many, precision is low, in manufacture and use procedure, be unfavorable for maintain and replace, after the loss of work band, must freeze and repeat again processing or scrap more to renew mould, be unfavorable for steady production and cost control.Because of the reason of this technique and structure, it is abnormal that the existence of metamorphic layer also can cause mould abnormal cracking, tube wall fineness deficiency, surperficial wire drawing etc. to produce aborning simultaneously.In addition the also same problem of ubiquity in the production of other similar unitary mould, use procedure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of stephanoporate thin wall aluminium-alloy pipe hot-extrusion mold is provided, and solves that existing integrative-structure mould process is complicated, blank is larger, the problems such as manufacture, production risk coefficient height.
The technical scheme providing according to the utility model, described stephanoporate thin wall aluminium-alloy pipe hot-extrusion mold, comprises upper die and lower die, and lower mold cavity arranges lower die model core, and upper mold cavity arranges patrix core; It is characterized in that: described patrix core and patrix are split-type structural, patrix core is fixed by screw and the patrix at middle part.
Described patrix core comprises core pipe, and the excircle of core pipe connects a plurality of forming parts, and forming part is connected with core pipe by reinforcement respectively.
Die cavity between described patrix core and lower die model core is the forming surface of aluminium-alloy pipe thin-walled.
Adopt stephanoporate thin wall aluminium-alloy pipe hot extruding die lamps structure described in the utility model can solve the various problems of integrative-structure mould when producing in prior art, as larger in complex process, blank, manufacture, production risk coefficient is high, particularly core plan metamorphic layer cannot all effectively be removed, the problems such as machining accuracy production lower and that cause thus in core cross section is abnormal reduce mold materials loss approximately 8% ~ 20% simultaneously.

The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 3～Fig. 4: as described in stephanoporate thin wall aluminium-alloy pipe hot-extrusion mold comprise patrix 1, counterdie 2, patrix core 3, core pipe 3-1, lower die model core 4, screw 5, die cavity 6, forming part 7, reinforcement 8 etc.
As shown in Figure 3, Figure 4, the utility model comprises patrix 1 and counterdie 2, and counterdie 2 inner chambers arrange lower die model core 4, and patrix 1 inner chamber arranges patrix core 3, and patrix core 3 is split-type structural with patrix 1, and patrix core 3 is fixing with patrix 1 by the screw 5 at middle part;
Die cavity 6 between described patrix core 3 and lower die model core 4 is the forming surface of aluminium-alloy pipe thin-walled, patrix core 3 comprises core pipe 3-1, the excircle of core pipe 3-1 connects a plurality of forming parts 7, forming part 7 is connected with core pipe 3-1 by reinforcement 8 respectively, and forming part 7 is respectively used to the moulding of aluminium-alloy pipe endoporus.
Hot-extrusion mold described in the utility model has solved mould production in prior art, use cost is high, the technical problem that process stability is limited.Hot-extrusion mold described in the utility model adopts split type patrix 1 and patrix core 3 to substitute original overall structure, and patrix core adds technological process corresponding to man-hour and is: blank is opened slightly, wire hole, heat treatment, finish turning inside and outside circle, line cutting section, electric spark forehand reinforcement, front and back sides grind metamorphic layer, front and back sides polishing.Add and make man-hour line cutting processing and the convenient metamorphic layer of removing become possibility.The hot extruding die lamps structure that the utility model adopts can be optimized for line cutting processing by patrix core cross section processing and forming spark machined in prior art, by originally repeating total hole count-1 of N(N=) inferior spark machined need simultaneously complete that N sub-electrode changes the outfit or the clamping workpiece senior machine tooling of rotation processing (or have), change to ordinary lines cutting off machine clamped one time, processing, improved dimensional accuracy form accuracy, simplified work flow, reduced production cost.And after energy cutting on line machines, carry out the grinding and polishing of part, remove electric spark on surface and process formed metamorphic layer, improve the surface smoothness of part.The structure that hot-extrusion mold described in the utility model adopts can reduce stock volume, can process separately spare unit by patrix core high for required precision, easy loss simultaneously, is beneficial to the replacing after loss in production or use procedure; Can promote by a relatively large margin the die life of this type of high accuracy tubing preparation process, and can, by changing in time high-quality core print, stablize production control process.
