Abstract
The invention relates to a micro-channel aluminum flat tube extrusion die which comprises a die ring, a die cushion and a die sleeve. The die ring, the die cushion and the die sleeve are sequentially connected. An upper die body and a lower die body are arranged in the die sleeve. Two pits are formed in the face, facing the die sleeve, of the die cushion. Radiators are arranged in the pits. The die ring is provided with an air inlet hole and an air outlet hole, wherein the air inlet hole communicates with an air inlet of one radiator, and the air outlet hole communicates an air outlet of the other radiator. The micro-channel aluminum flat tube extrusion die is provided for overcoming the defect in the aspect of design of an aluminum flat tube extrusion die in the prior art; and the micro-channel aluminum flat tube extrusion die is good in radiating effect, long in service life and capable of better increasing the extrusion speed, and therefore the yield of aluminum flat tubes is increased.
Description
Technical field
The present invention relates to a kind of extrusion mould, especially a kind of aluminium flat conduit extrusion mould.
Background technology
The cross-sectional area of microchannel aluminium flat conduit is very little, generally at 10mm2Left and right, even if therefore adopting porous extruding, its extrusion ratio still can extrude the extrusion ratio of specification 8��50 times considerably beyond conventional aluminum, and reaches about 500 times, so big extrusion ratio, at all extrusion speed as traditionally can talk without output, this product of extruding in the past, owing to mould temperature rise is too high and temperature cannot be lowered, the method therefore adopted is generally the speed lowering extruding, reducing to 50m/min, the result caused like this has been production loss 28.47%. Therefore to be improved output and just must improve extrusion speed, 70m/min is brought up to from traditional 50m/min, but so high extrusion speed can make the rise in temperature of mould to more than 610 DEG C, common hot-work die steel is made to be in tempering and as-annealed condition, will be very fast because lose the life-span without hardness.
Summary of the invention
It is an object of the invention to solve the deficiency of aluminium flat conduit extrusion mould design aspect in prior art, it is provided that a kind of microchannel aluminium flat conduit extrusion mould, its good heat dissipation effect, it may also be useful to the life-span is long, be conducive to improving extrusion speed, thus improve aluminium flat conduit output.
Technical scheme
A kind of microchannel aluminium flat conduit extrusion mould; comprise mould ring, die-cushion and mould cover that order connects; mould is provided with upper die and lower die in overlapping; the one side that die-cushion overlaps towards mould is provided with two pits; scatterer it is equipped with in pit; being provided with air inlet port and production well on mould ring, air inlet port is connected with the inlet mouth of scatterer, and production well is connected with the air outlet of scatterer.
Further, described scatterer is fine copper scatterer. The heat conductivility of fine copper is extremely high, and it can be delivered to the heat of mould in whole scatterer fast.
Further, described scatterer comprises the air-flow passage of vertical and horizontal, and radiating effect is better.
During use, constantly pouring the lyophilize air of 0.2��0.3MPA pressure in air inlet port, the gas being filled with can take away rapidly the heat in fine copper scatterer, so circulates simultaneously, mould just can be made to remain among the temperature of 560 DEG C��580 DEG C, reach the object of crushing failure at high speed.
Useful effect: the microchannel aluminium flat conduit structure of extrusion of the present invention is simple, easy to operate, good heat dissipation effect, it may also be useful to the life-span is long, is conducive to improving extrusion speed, thus improves aluminium flat conduit output.
Accompanying drawing explanation
Fig. 1 is the structural representation of microchannel of the present invention aluminium flat conduit extrusion mould;
Fig. 2 is the A-A direction view of die-cushion in Fig. 1;
Wherein, 1-mould ring, 2-die-cushion, 3-mould cover, 4-patrix, 5-counterdie, 6-scatterer, 7-air inlet port, 8-production well.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of microchannel of the present invention aluminium flat conduit extrusion mould, Fig. 2 is the A-A direction view of die-cushion in Fig. 1, such as diagram, a kind of microchannel aluminium flat conduit extrusion mould, comprise the mould ring 1 that order connects, die-cushion 2 and mould cover 3, it is provided with patrix 4 and counterdie 5 in mould cover 3, the one side of die-cushion 2 towards mould cover 3 is provided with two pits, scatterer 6 it is equipped with in pit, mould ring 1 is provided with air inlet port 7 and production well 8, air inlet port 7 is connected with the inlet mouth of scatterer 6, production well 8 is connected with the air outlet of scatterer 6, scatterer 6 is fine copper scatterer, comprise the air-flow passage of vertical and horizontal.
During use, constantly pouring the lyophilize air of 0.2��0.3MPA pressure in air inlet port, the gas being filled with can take away rapidly the heat in fine copper scatterer, so circulates simultaneously, mould just can be made to remain among the temperature of 560 DEG C��580 DEG C, reach the object of crushing failure at high speed.
The microchannel aluminium flat conduit structure of extrusion of the present invention is simple, easy to operate, good heat dissipation effect, it may also be useful to the life-span is long, is conducive to improving extrusion speed, thus improves aluminium flat conduit output.
