Abstract
The present invention relates to a kind of microchannel aluminium flat conduit extrusion die; including modular ring connected in order, die-cushion and die sleeve; upper die and lower die are provided with die sleeve; two pits are provided with one side of the die-cushion towards die sleeve; radiator is equipped with pit; air admission hole and venthole are provided with modular ring, air admission hole connects with the air inlet of radiator, and venthole connects with the gas outlet of radiator.The present invention solves the deficiency in terms of aluminium flat conduit Extrusion Die Design in the prior art, there is provided a kind of microchannel aluminium flat conduit extrusion die, its good heat dissipation effect, service life length, is advantageous to improve extrusion speed, so as to improve aluminium flat conduit yield.
Description
Technical field
The present invention relates to a kind of extrusion die, especially a kind of aluminium flat conduit extrusion die.
Background technology
The cross-sectional area of microchannel aluminium flat conduit is very small, typically in 10mm2Left and right, therefore even if using porous extruding,
Its extrusion ratio still can be considerably beyond the extrusion ratio of traditional 8~50 times of aluminium extrusion specification, and reaches 500 times or so, so big
Extrusion ratio, it can such as be talked without yield at all according to traditional extrusion speed, extrude the product in the past, because mould temperature rise is too high
And temperature can not be lowered, therefore the method used is generally the speed for lowering extruding, reduces to 50m/min, so causes
Result be production loss 28.47%.Therefore extrusion speed must be just improved if improving yield, from traditional 50m/
Min brings up to 70m/min, but so high extrusion speed can make the temperature of mould rise to more than 610 DEG C, makes common heat
Make mould steel and be in tempering and annealed condition, it will quickly because losing the life-span without hardness.
The content of the invention
Present invention aim to address the deficiency in terms of aluminium flat conduit Extrusion Die Design in the prior art, there is provided a kind of micro- logical
Road aluminium flat conduit extrusion die, its good heat dissipation effect, service life length, be advantageous to improve extrusion speed, so as to improve aluminium flat conduit production
Amount.
Technical scheme
A kind of microchannel aluminium flat conduit extrusion die, including modular ring connected in order, die-cushion and die sleeve, die sleeve is interior to be provided with upper mould
With lower mould, two pits are provided with one side of the die-cushion towards die sleeve, radiator is equipped with pit, air inlet is provided with modular ring
Hole and venthole, air admission hole connect with the air inlet of radiator, and venthole connects with the gas outlet of radiator.
Further, the radiator is fine copper radiator.The heat conductivility of fine copper is high, and it can be rapidly the heat of mould
Amount is delivered in whole radiator.
Further, the radiator includes the gas channel of vertical and horizontal, and radiating effect is more preferable.
In use, simultaneously toward the freeze-drying air that 0.2~0.3MPA pressure is constantly poured in air admission hole, the gas being filled with
The heat in fine copper radiator can be taken away rapidly, so circulation, among mould can be made to be maintained at 560 DEG C~580 DEG C of temperature,
Reach the purpose of crushing failure at high speed.
Beneficial effect：The microchannel aluminium flat conduit structure of extrusion of the present invention is simple, easy to operate, good heat dissipation effect, makes
With long lifespan, be advantageous to improve extrusion speed, so as to improve aluminium flat conduit yield.

Wherein, 1- modular rings, 2- die-cushions, 3- die sleeves, the upper moulds of 4-, mould under 5-, 6- radiators, 7- air admission holes, 8- ventholes.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 be microchannel aluminium flat conduit extrusion die of the present invention structural representation, Fig. 2 be Fig. 1 in die-cushion A-A to regarding
Figure, as shown, a kind of microchannel aluminium flat conduit extrusion die, including modular ring 1 connected in order, die-cushion 2 and die sleeve 3, set in die sleeve 3
There are upper mould 4 and lower mould 5, two pits are provided with one side of the die-cushion 2 towards die sleeve 3, radiator 6 are equipped with pit, in mould
Ring 1 is provided with air admission hole 7 and venthole 8, and air admission hole 7 connects with the air inlet of radiator 6, the outlet of venthole 8 and radiator 6
Mouth connection, radiator 6 is fine copper radiator, includes the gas channel of vertical and horizontal.
In use, simultaneously toward the freeze-drying air that 0.2~0.3MPA pressure is constantly poured in air admission hole, the gas being filled with
The heat in fine copper radiator can be taken away rapidly, so circulation, among mould can be made to be maintained at 560 DEG C~580 DEG C of temperature,
Reach the purpose 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, service life length,
Be advantageous to improve extrusion speed, so as to improve aluminium flat conduit yield.
