Abstract
The utility model relates to a one-die multiple-part aluminum alloy tube hot-extrusion die, which is assembled and combined by an upper die and a lower die. A feeding end of the lower die is provided with a soldering chamber and a cavity, a discharge hole is processed at a discharge end of the lower die, a pressure reduction counter bore is arranged at a feeding end of the upper die, flow distribution holes of the upper die and the cavity of the lower die are in twofoldness distribution, namely the flow distribution holes are uniformly distributed surrounding the cavity of the lower die, all bridge sites of the upper die are processed into water-drop-shaped structures, a plurality of square-headed die cores are arranged on a discharge surface of the upper die, and supporting bosses are disposed among the square-headed die cores and are directly tightly attached with the bottom of the soldering chamber of the lower die. The one-die multiple-part aluminum alloy tube hot-extrusion die resolves the problem that products manufactured by a one-die multiple-part tube die are non-uniform in wall thickness, difference of flow speeds is high and rejection rate is high, and has the advantages of uniform wall thicknesses of extruded products, identical flow speeds and high yield.
Description
Technical field
The utility model relates to a kind of aluminium section hot-extrusion die, and the hot extrusion of main aluminium alloy pipe belongs to the mold machining technology field.
Background technology
Developing rapidly of World Economics, increasing to the demand of various resources, but a lot of valuable source is limited, non-renewable, how to save energy and reduce the cost just becomes our present sixty-four dollar question.After aluminium alloy was developed as product material, its unique advantage was recognized the world over, and application is more and more widely, had related to all trades and professions now.Wherein aluminium alloy pipe is the maximum kind of aluminium product consumption, and aluminium section bar manufacturer is in order to enhance productivity, to reduce production costs, and all the direction that has more towards a mould develops.But the wall unevenness of article of manufacture is even at present, and the speed of flow velocity differs greatly, the percent defective height is a hard nut to crack of puzzlement aluminium section bar manufacturer development.In actual production,, all do not obtain obvious effects although adopted some measures.If it can not effectively be solved always, just can't realize the doulbe-sides' victory of enterprise's production cost and production efficiency.
The utility model content
The utility model purpose is to overcome a mould and has more that the wall unevenness of pipe mold article of manufacture is even, the problem that speed differs greatly, percent defective is high of flow velocity, provides that a kind of extruded product wall thickness is even, flow velocity is consistent, an one-die multiple-part aluminium alloy tube hot-extrusion die of high finished product rate.
The technical solution adopted in the utility model:
An a kind of one-die multiple-part aluminium alloy tube hot-extrusion die, form by the upper die and lower die assembly, described counterdie feed end is provided with seam chamber and die cavity, discharge end is processed with discharge opening, described patrix feed end is provided with the decompression counterbore, the tap hole of patrix adopts with the die cavity of counterdie and becomes multiple to distribute, described one-tenth multiple distribution be a plurality of tap holes die cavity of being evenly arranged in counterdie around, all bridge locations of patrix are processed into water droplet shape structure; The charge level that goes out of described patrix is provided with a plurality of square toes core rods, is provided with support rim between the described square toes core rod, and this support rim directly and bottom the seam chamber of counterdie is adjacent to.
The technique effect that the utility model is obtained:
1, the utility model patrix tap hole adopts and the number distribution at double of counterdie die cavity, be arranged in the counterdie die cavity around, allow each die cavity look approximate independent, but by three or three above tap holes and bridge location control feed, so just guarantee the stability of square toes core rods, avoided the seam line on section bar surface again;
2, the patrix feed end is provided with the decompression counterbore, and all bridge locations are processed into water droplet shape structure, like this with regard to effectively reduced because of bridge location be provided with many on the pressure that is molded as;
3, patrix is provided with a boss in the middle of the square toes core rod of discharge end, it directly and bottom the counterdie seam chamber is adjacent to, its effect is exactly to support patrix, the strain that allows the patrix bridge location produce is reduced to minimum, can effectively control the beat of wall thickness like this, strengthen the stability of mould discharging, prolong the service life of mould again.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the cutaway view at the A-A place of the present utility model.
Wherein, patrix 1, counterdie 2, pin 3, screw 4; Decompression counterbore 1.1, tap hole 1.2, bridge location 1.3, support rim 1.4, square toes core rod 1.5; Seam chamber 2.1, die cavity 2.2, discharging opening 2.3.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to Fig. 1-2, an one-die multiple-part aluminium alloy tube hot-extrusion die adopts pin 3 and screw 4 assemblies to form by patrix 1 and counterdie 2.Described patrix 1 feed end is provided with the decompression counterbore 1.1 of sinking 10mm.The tap hole 1.2 of patrix 1 adopts the 2.2 one-tenth multiples distributions of die cavity with counterdie 2, and be arranged in counterdie 2 die cavity 2.2 around.All bridge locations 1.3 of patrix 1 are processed into water droplet shape structure, as Fig. 5.The charge level that goes out of patrix 1 is provided with a plurality of square toes core rods 1.5, is provided with support rim 1.4 between the described square toes core rod 1.5.The square toes core rod 1.5 of patrix 1 crosses along slipping over bridge location 1.3.Described counterdie 2 feed ends are provided with seam chamber 2.1, and discharge end is processed with discharge opening 2.3.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
