Abstract
The invention relates to a hot extrusion die of aluminum alloy pipes with multiple output, in particular to the hot extrusion of the aluminum alloy pipes and is formed by assembling and combining an upper die (1) and a lower die (2), wherein, a feeding end of the lower die (2) is provided with a welding chamber (2.1) and a die cavity (2.2) and a discharging hole (2.3) is processed at a discharging end of the lower die (2); the feeding end of the upper die (1) is provided with a decompress counter bore (1.1), and split flow holes (1.2) of the upper die (1) are distributed in a multiplied way with the die cavity (2.2) of the lower die (2) and are positioned at the circumference of the die cavity (2.2) of the lower die (2); all bridge sites (1.3) of the upper die (1) are processed into water drop structure; the discharging surface of the upper die (1) is provided with a plurality of square head die cores (1.5) which are provided with a support lug boss (1.4) among the square head die cores (1.5), and the lug boss (1.4) is closely and directly attached to the bottom part of the welding chamber (2.1) of the lower die (2); the square head die cores (1.5) and the bridge sites (1.3) are transited smoothly. The hot extrusion die can cause the extrusion products of the aluminum alloy pipes to be uniform in wall thickness, consistent in flow rate and high in rate of finished products.
Description
(1) technical field
The present invention relates to a kind of aluminium section hot-extrusion die.The hot extrusion of main aluminium alloy pipe.Belong to the mold machining technology field.
(2) 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.
(3) summary of the invention
The objective of the invention is to overcome a mould and have 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, provide 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 object of the present invention is achieved like this: an a kind of one-die multiple-part aluminium alloy tube hot-extrusion die, form by the upper die and lower die assembly, and it is characterized in that:
Described counterdie feed end is provided with seam chamber and die cavity, and discharge end is processed with discharge opening,
Described patrix feed end is provided with the decompression counterbore, and the tap hole of patrix adopts and becomes the multiple distribution with the die cavity of counterdie, and be arranged in counterdie die cavity 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, and described square toes core rod and bridge location cross along slipping over.
Compare with existing similar mould, the utility model mould has following characteristics:
1, the 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, and it directly and bottom the counterdie seam chamber is adjacent to, and its effect is exactly to support patrix, and 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.
By above-mentioned improvement, the present invention can make the aluminium alloy pipe that the extruded product wall thickness is even, flow velocity is consistent, yield rate is high.
