Along with the development and progress of solid-state mutually empty array antenna technology, the integrated degree of antenna is more and more higher.In antenna, be integrated with solid-state T/R assembly, the high-power heater members such as power supply, these high power devices are responsive especially to the requirement of temperature, and excess Temperature or non-uniform temperature can cause the decline of antenna overall performance, thereby reduce the Stability and veracity of radar signal.At present the heat radiation research emphasis of solid state phased array antenna is concentrated on the water-cooling channel forming technique aspect of the efficient cold drawing of structure water-cooled integrated component, how to manufacture a kind of low thermal resistance, the structure water-cooled integrated component of high cooling efficiency becomes the key of solid state phased array antenna heat radiation.
Common structure water-cooled integrated component is the prolate type aluminium alloy hollow plate that comprises several water-cooling channels, and its classical production process mainly contains: the butt welding of half block metal substrate, pipe laying method, pipe laying casting and two-way positional punch.A series of defects and the deficiencies such as these traditional processing methods can cause such as welding point seepage, and water cooling structure part structural strength is low and production efficiency is low, and yield rate is low.Therefore, structure water-cooled integrated component progressively adopts bridge die extrusion to produce present stage.Yet, strict demand due to operations such as Structure weight reduce and follow-up machined, welding, diameter≤the 5mm of most of water-cooling channel, this type of architectural feature has proposed very high requirement to the stability of minor diameter divergent die core rod, the unreasonable of Design of Dies will cause core rod to produce the elastic-plastic deformation perpendicular to the direction of extrusion, cause the hole shape deviation of water-cooling channel excessive, reduce yield rate and production efficiency.Existing water cooling structure part shunting extrusion die, its core rod diameter or size remain unchanged along the direction of extrusion, and core rod termination comprises work band, cause core rod termination diameter or size to be greater than core rod root, this architectural feature core rod, the in the situation that of water-cooling channel diameter≤5mm, very easily produces even plastic lateral deformation of lateral elasticity bending, cannot guarantee the glacing flatness of water-cooling channel on the one hand, on the other hand, larger lateral thrust degree can cause core rod timeliness, and divergent die is scrapped.
Utility model content
The purpose of this utility model is: the existing shunting extrusion die of pin is not suitable for the production of the water cooling structure part that comprises extra small bore diameter water-cooling channel, and a kind of aluminium alloy cooled plate shunting extrusion die that comprises extra small diameter core rod proposing, this mould also helps the service life that extends shunting extrusion die.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of aluminium alloy cooled plate shunting extrusion die that comprises extra small diameter core rod, comprise upper die and lower die, described patrix is evenly distributed with a plurality of tap holes around centre, between tap hole, be provided with shunting bridge, the centre of shunting bridge is provided with and the core rod of shunting bridging and being integrated, core rod extends and protrudes patrix along the direction of extrusion, described counterdie is provided with seam chamber, described middle part, seam chamber is provided with the nib of getting through, between nib and the end of core rod, form width for the gap of the water-cooled sheet material wall thickness produced of shunting extrusion die, the diameter of described core rod and shunting bridge coupling part is greater than the diameter of mandrel tip.
Described a kind of aluminium alloy cooled plate shunting extrusion die that comprises extra small diameter core rod, described core rod cross-sectional diameter remains unchanged after reducing gradually along core rod and shunting bridge coupling part to mandrel tip is first tapered, the tapered part reducing of cross-sectional diameter forms core rod root, and the angle between core rod root hypotenuse and core rod axis direction is 15 °～30 °.
Technique effect of the present utility model is, can guarantee stability and the resistance to lateral bending ability of extra small diameter core rod, avoids the lateral elasticity distortion of core rod, can push and produce the aluminium alloy water-cooled sheet material that comprises extra small diameter limbers.
