Abstract
The invention relates to a circular tube forming fan-blade type divergent upper die and a corresponding divergent die of the circular tube forming fan-blade type divergent upper die. The bridge of the circular tube forming fan-blade type divergent upper die comprises a surface, a curved side surface and a straight side surface; the curved side surface is waved and comprises a first concave part, a second concave part and a convex part, wherein the two ends of the convex part are connected to the first concave part and the second concave part, respectively, and the three parts are in smooth transition with each other; the two outer side ends of the first concave part and the second concave part are connected to the straight side surface, respectively, and together form a fan-blade-shaped bridge. The circular tube forming fan-blade type divergent die comprises the upper die. A cambered transition surface (7) is formed between the curved side surface (2) and the surface (1). The circular tube forming fan-blade type divergent upper die and the corresponding divergent die of the circular tube forming fan-blade type divergent upper die provided by the invention are simple in structure and ingenious in design; and the fan-blade-shaped bridge obviously improves the welding-on property of the extrusion product and the use safety coefficient of the extrusion product, and simultaneously also improves the extrusion efficiency.
Description
Technical field
The present invention relates to a kind of shaping round tube fan leaf type shunting patrix and corresponding divergent die thereof.
Background technology
The hot extrusion pipe is divided into all size goods of light-wall pipe (wall thickness≤5mm) and thick-walled pipe (wall thickness〉5mm) by wall thickness, thick-walled tube is applied to guarantee after turning processing some assembly parts of precision, generally plays the load-bearing effect; The follow-up manufacturing procedures such as cold-heading, reducing, bending, cold-drawn that generally are accompanied by of thin-wall circular tube, its requirement to pipe itself lay particular emphasis on mainly that high ductibility, dimensional accuracy are high, seam performance height etc.On processing technology, the extruding pipe has 2 types.One uses the seamless pipe of punching technology extruding, and this pipe itself is seamless, safe, but that shortcoming is dimensional accuracy is low, needs adjust dimensional accuracy by the follow-up operations such as multiple tracks is cold rolling, cold-drawn of carrying out, and wastes time and energy, processing charges is difficult to bear.Its two, produce seamed pipe by combination die technology extruding, this pipe dimensional accuracy is higher, although follow-uply also will carry out cold rolling, cold-drawn processing, at least reach more than 50% but reduced manufacturing procedure compared with seamless pipe processing, make it greatly save cost, can be applied on a large scale.But seamed pipe is due to mould self structure factor, and at least 2 seam lines inevitably can appear in pipe, and after the client, extended meeting relates to the burst pressure test, air tightness test detects tubing seam feature.According to market feedback information, some pipe applications secondary suppliers clearly propose now, can use seamed pipe, but prerequisite is to guarantee high seam, generally judge to detect pipe enlarging rate, what require that the enlarging rate reaches body could judge more than 1.2 times that pipe is qualified.Generally can only reach reluctantly requirement on market, safety coefficient is nowhere near, and there is very big hidden danger in product quality.
Summary of the invention
The technical problem to be solved in the present invention is the defects that how to overcome prior art, and a kind of shaping round tube fan leaf type shunting patrix and corresponding divergent die thereof are provided.
For solving the problems of the technologies described above, the bridge of this shaping round tube fan leaf type shunting patrix comprises surface (1), bent side (2) and straight sided (3), described bent side (2) undulate, comprise the first recess (4), the second recess (5) and protuberance (6), wherein protuberance (6) two ends connect respectively the first recess (4) and the second recess (5), three parts seamlessly transit, the first recess (4), the second recess (5) two outboard ends connect respectively straight sided (3), jointly surround the bridge of flaabellum shape.
As optimization, be equipped with arc transiting surface (7) between described bent side (2) and surface (1).
As optimization, described arc transiting surface (7) is the arc transiting surface of evagination.
As optimization, described arc transiting surface (7) is the arc transiting surface of indent.
As optimization, the quantity of described bridge has three, and the sectional area of these three bridges is identical.
So design, the bridge of divergent die is designed to flabellum shape, make it possible to realize crushing failure at high speed, general extrusion speed 3 line aluminium alloys 〉=30m/min, 6 line aluminium alloys 〉=20m/min, extruding efficient is more than 3 times of traditional design divergent die, greatly reduce processing cost, and the seam performance obtains rapid progress, and after tested, 3 line aluminium alloy pipe enlarging rates reach more than 1.5 times, even reach capacity 1.8 times, greatly improved the safety coefficient that seamed extruding pipe uses.
This shaping round tube fan leaf type divergent die is the divergent die that comprises above-mentioned patrix.
A kind of shaping round tube fan leaf type of the present invention shunts patrix and corresponding divergent die is simple in structure, the design is ingenious, and the design of fan leaf type bridge has significantly improved the seam of extruded product and the safety coefficient that extruded product uses, and has also promoted simultaneously extruding efficient.
