General to be squeezed using mold to produce microchannel aluminium flat conduit, mould and die accuracy and service life directly affect the microchannel aluminium produced
The quality of flat tube.In the prior art, aluminium flat conduit extrusion die is made of common wolfram steel, the disadvantage is that its pressure that can bear
Small, hardness is not high, and it is shorter to benefit from the service life, it is difficult to complete complicated microchannel aluminium flat conduit production task.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of aluminium flat conduit extrusion coating moulds
Tool, hardness is high, can bear biggish extrusion pressure, long service life, the microchannel aluminium flat conduit flatness and yield rate squeezed out
It is improved.
To achieve the above object, the utility model adopts the following technical solution
A kind of aluminium flat conduit extrusion die of coating, including upper die and lower die, its main feature is that the upper mold is boss shape
The internal hollow cylinder of variable diameter, upper mold upper surface set bridge along cylindrical cross-section circular diameter direction, and chip is set on the bridge, and bridge two sides are set
Feed opening, upper mold upper surface are additionally provided with two cylindrical card slots；The chip is higher by upper mold upper surface；The lower die is and upper mold
Cylindrical first groove and upper mold variable diameter cylindrical fit is arranged in the cylinder of cooperation, lower die upper surface, and the is set in the middle part of the first groove
Two grooves set flat tube molding hole in the second groove, and the flat tube molding hole is consistent with aluminium flat conduit shape, cooperate with chip and constitute aluminium
The flat tube discharge hole being connected to flat tube molding hole, the first groove and the second groove is arranged in flat tube ontology cross sectional shape, lower die bottom
Between be additionally provided with the cylindrical protrusions being oppositely arranged with card slot, inlay fixation for upper die and lower die；The upper die and lower die
Outer surface is coated with alumina layer.
Further, the alumina layer with a thickness of 0.002-0.003mm.
Further, the upper die and lower die set corresponding bolt hole, using being bolted, increase its bonding strength, hold
By bigger crushing strength.
Further, the outer surface of the upper die and lower die is in truncated cone, guarantees that die ontology begins in pressure process
Position of center line is being squeezed out eventually, is guaranteeing the precision of aluminium flat conduit production.
Further, the chip structure is according to aluminium flat conduit specifications design.
Compared with prior art, the utility model has the advantages that die hardness is high, biggish extrusion pressure can be born, is used
Service life is long；When squeezing production, the truncated cone design of upper die and lower die facilitates die ontology and exists always under larger pressure
Position of center line is squeezed out, guarantees that the microchannel aluminium flat conduit flatness squeezed out is high, subsequent machining technology can be born, improve aluminium flat conduit
Yield rate.
