Description
Technical field
This utility model belongs to small dimension precision die processing technique field, particularly relates to a kind of plane distribution composite die preparing gap hollow aluminium alloy section bar.
Background technology
At present, the extruding of small dimension Precision Aluminum alloy hollow product forms is main adopts plane distribution composite die extruding to produce, the goods obtained by the method have section structure complicated and changeable, produce equipment precision requirement is low, production cost is low, efficiency high, the Precision Aluminum alloy product that the method is made is widely used in electronic machine, communication equipment, national defence tip precision optical machinery, precision instrument, nuclear submarine and the field such as boats and ships, auto industry.Traditional plane distribution composite die adopts the mode that set breaks into type to complete the processing of core rod and nib, completes for the processing mode inlayed after the core rod employing parts processing of the especially complex class mould of mold insert structure.For a class multi-pore channel gap aluminum alloy hollow section series products, this series products is because of gap width little (0.2～0.5mm), gap length big (1～5mm), and length-width ratio is generally 5～25, is difficult to ensure molding by the mould structure of rigidity.
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of plane distribution composite die preparing gap hollow aluminium alloy section bar, it is characterised in that positioned assembling by upper die and lower die by seam 7 and pin 8, be crushed to hollow profile product；Several tap holes 1 it are provided with in upper mould, forming shunting bridge 2 between each tap hole, centre is provided with core rod 3, and counterdie is sequentially provided with bonding container 4, nib 5 and empty cutter 6 from top to bottom, bonding container 4 connects with the tap hole 1 of upper mould, and the core rod 3 of upper mould is inserted in the nib 5 of counterdie；
There is a through wire hole 9 at core rod 3 position of described upper mould, has a tinsel 10 in wire hole 9, and wire hole 9 two ends processing taper bevel for welding 11 is used for burying tinsel two ends and knots.
Described tap hole 1 is all in horn-like extension.
The material of described tinsel 10 is nickel or cobalt or the metal material suitable with the elevated temperature strength of H13 steel and toughness.
The H13 steel welding wire welding of described bevel for welding 11 is filled and led up.
Described wire hole 9 diameter 0.03mm～0.05mm bigger than tinsel 10 diameter.
Beneficial effect
This utility model provides a kind of plane distribution composite die preparing gap hollow aluminium alloy section bar, solves the problems such as traditional moulds processing method cannot be processed or mould manufacturing procedure precision complicated, uncontrollable, manufacture and maintenance cost be high；This utility model is applicable to the porous gap aluminium alloy pipe of the aluminum alloy material that all employing divergent dies produce hollow profile and produces, the mode wearing filament is adopted to complete the machine-shaping of position, product gap mould, this configuration reduces mould difficulty of processing, add die life, the Mold Metal silk prepared can be replaced after damaging, and greatly reduces follow-up maintenance cost.

Detailed description of the invention
Below in conjunction with Figure of description and one group of specific embodiment, this utility model is further described.
Embodiment discloses a kind of plane distribution composite die.Fig. 1 is the product structure figure of the gap hollow aluminium alloy section bar that this utility model is suitable for, Fig. 2 is the product partial enlarged drawing of the gap hollow aluminium alloy section bar that this utility model is suitable for, product is " 8 " font diplopore hollow profile, one " one " shaped base is had below " 8 " word, an elongated gap is there is between holes, gap width 0.2mm, length 1.5mm, length-width ratio is 7.5.This series products according to traditional dies, is then gone up and is needed a piece diameter 0.2mm of processing between mould two core rod, and the crossbeam of long 1.5mm, difficulty of processing is big and the life-span is short.
Fig. 3 is mould elevation cross-sectional view on plane distribution composite die of the present utility model, and Fig. 4 is the partial enlarged drawing that on plane distribution composite die of the present utility model, the core rod of mould wears a structure.Two core rods of upper mould process a through wire hole at work strip 2/3 position, diameter 0.25mm, two ends, hole processing taper bevel for welding, the tinsel material connected between core rod is Inconel718 alloy, diameter 0.2mm, connect the knotting of tinsel two ends fixing, fill up the bevel for welding at wire hole two ends with H13 steel welding wire；This design structure effectively instead of rigid elongate beam structure.
Fig. 5 is top view and the sectional view of plane distribution composite die counterdie of the present utility model, and Fig. 6 is the sectional view of plane distribution composite die counterdie of the present utility model；Counterdie includes bonding container, nib and discharging opening.
This utility model is applicable to the porous gap aluminium alloy pipe of the aluminum alloy material that all employing divergent dies produce hollow profile and produces, the structure adopting tinsel traverse wire hole completes the machine-shaping of position, product gap mould, this configuration reduces mould difficulty of processing, add die life, the Mold Metal silk prepared can be replaced after damaging, greatly reducing follow-up maintenance cost, the product inner surface quality obtained and gap size all meet designing requirement.
