Abstract
The invention relates to a non-flash die for extruding aluminum alloy shell parts. The non-flash die mainly comprises a female die, a male die, a cavity, curved surface teeth, a left female die, a right female die, positioning holes, screw holes, a threaded connection part and pin holes and is improvement on an extrusion forming die aiming at the condition that flashes are easily generated in the process of extruding the aluminum alloy branched shell parts. According to the non-flash die, the curved surface teeth are formed additionally on the conical part of the female die, so that oddments and flowing metal which are generated in the extrusion process are restrained and blocked, and the flashes are prevented from being generated; through introduction of the male die, mutually meshed curved teeth are increased, and the residual free space in which the flowing metal can flow is reduced, so that the probability of forming the flashes is reduced; and therefore, the flashes are not generated when the branched shell parts are extruded, the extrusion forming quality and efficiency are improved, metal materials are saved, and the non-flash die is very ideal and can be applied to extrusion forming of various similar parts.
Description
Technical field
The present invention relates to a kind of non-trimming mould of extruding aluminium alloy housing part, belong to the branch art field of mechanical Design of Dies and application.
Background technology
Along with scientific and technical development, the kind of parts is more and more, required precision is more and more higher, in Aero-Space, weapon industry, have a lot of fork classes, gusset shells part, not only complex-shaped, its requirement of strength is more and more higher, in order to make to equip lightweight, the normal alloy in lightweight that adopts, aluminium alloy for example, this will ask moulding process to reach a new technology height.
The material Aluminium Alloys in Common Use of housing branch fork part, its processing method mostly adopts metal mould forming, in traditional open die, must design flash gutters, the weight of the part overlap after moulding reaches the 10-35% of gross weight, and then adopt machining to remove overlap, both wasted a large amount of materials and energy consumption, the service life of having reduced again mould, improve the processing cost of part, therefore produce overlap in extruding branch fork part process, become a difficult problem.
Summary of the invention
Goal of the invention
The object of the invention is the situation for background technology, design a kind of non-trimming extrusion die for moulding aluminium alloy branch fork part, the design that adopts punch, die to combine, on die joint in concave die cavity, design curved surface tooth, at extrusion process mean camber tooth, first mesh, control the metal flow at die joint middle part, shelves are lived the moulding distortion of metal, make it not produce overlap.
Technical scheme
Primary structure of the present invention comprises: punch, die; Punch comprises threaded joints, installing hole, punch installing hole, punch forming part, punch tapered portion, punch extend portion, punch neck; Die comprises neck, mounting-positioning holes, lifting screw under neck on die cavity, curved surface tooth, bottom curved surface tooth, branch fork forming part, mold cavity forming portion, die cavity tapered portion, die cavity;
Die is that forward is cone-shaped, by left part die, right part die, form overall structure, die middle chamber is comprised of neck under neck, mold cavity forming portion, die cavity tapered portion, die cavity on die cavity, in die cavity tapered portion, be provided with curved surface tooth, in the bottom of curved surface tooth, be provided with bottom curved surface tooth, in die cavity tapered portion bottom, be provided with branch fork forming part; In the centre position of die outside, divide symmetrical the first mounting-positioning holes, the second mounting-positioning holes of being provided with, in the top of die outside symmetry, be vertically provided with the first lifting screw, the second lifting screw;
Punch, for oppositely cone-shaped, is an integral body, and top is punch threaded joints, and threaded joints bottom is punch neck, and punch neck bottom is punch tapered portion, and punch tapered portion bottom is punch forming part, and punch forming part bottom is the punch portion that extends; Minute symmetrical the first installing hole, the second installing hole of being provided with on punch neck, punch neck centre position is provided with punch installing hole.
Described die is by the symmetrical overall structure that forms of left part die, right part die, and left part die, right part die shape, structure, size are just the same, are assembled into overall structure after machine-shaping.
Described curved surface tooth is comprised of interconnective rectangle teeth groove, suppresses the generation of overlap in branch fork housing part extrusion process.
Beneficial effect
The present invention compares with background technology has obvious advance, in extrusion process, easily to produce the actual conditions of overlap for aluminium alloy branch fork housing part, extrusion molding dies is improved, die cavity tapered portion at die has been set up curved surface tooth, make the clout that in extrusion process die joint produces and mobile metal is restrained blocks, hindered the formation of overlap, along with advancing of punch, intermeshing curved surface tooth is more and more, the remaining free space for metal flow is fewer and feweri, the chance that makes to form overlap also can be more and more less, thereby make branch fork part in extrusion process, not produce overlap, improved the quality of branch fork housing part extrusion modling, saved metal material, improved extruding efficiency, it is the non-trimming extrusion die that very good Al-alloy casing branch is pitched part, this mould structure can be used for the extrusion modling of multiple like parts.
