Summary of the invention
The object of this invention is to provide a kind of production method of the aluminium alloy radiator sectional material with spiral fins, while completing section bar extrusion, traction, its linear pattern radiating fin is processed into screw type, and machining accuracy is high, good product quality.
The technical solution adopted for the present invention to solve the technical problems is: by mould, positioning disk, rolling disc, the production method of a kind of aluminium alloy radiator sectional material with spiral fins of draw-gear composition, the port of export all with the extrusion die counterdie of linear pattern radiating fin inside and outside radiating tube fixes a positioning disk, the outside of positioning disk is provided with helical rotation device, the entrance point of helical rotation device is provided with rolling disc, the outside of helical rotation device is provided with draw-gear, rotating section bar special fixture is provided with in draw-gear, the bottom of draw-gear is provided with walking track, its production method is: the aluminium ingot after intensification is under the brute force of extruder promotes, counterdie is entered through patrix tap hole, then extrude from the nib of counterdie, pass through positioning disk, become radiating tube inside and outside all with the section bar of linear pattern radiating fin, under extruder continues promotion, the head of section bar enters helical rotation device through rolling disc, draw-gear is entered again from the rear portion of helical rotation device, and the section bar special fixture be arranged on draw-gear clamps locking, the linear pattern radiating fin of section bar surrounding is along with in some the fin grooves corresponded entered on positioning disk and rolling disc inner periphery, rolling disc rotates in the lump together with the section bar in it under driven by motor, because positioning disk maintains static, section bar between positioning disk and rolling disc produces and reverses, linear pattern radiating fin on section bar is inside and outside produces screw type plastic deformation, along with draw-gear guides section bar constantly to extend along its walking track, rolling disc is along with rotation, section bar between positioning disk and rolling disc constantly produces screw type plastic deformation, produce the aluminium alloy radiator sectional material with spiral fins.
In described technical scheme, the hauling speed of draw-gear is identical with the extruded velocity of mould, and speed is adjustable.
In described technical scheme, on draw-gear, the revolution of rotating section bar special fixture is identical with the rolling disc revolution on helical rotation device; Section bar special fixture on draw-gear and the rolling disc synchronous axial system on helical rotation device.
Device structure of the present invention is reasonable, simply applicable, the linear pattern radiating fin on shaped material of radiator can be processed into screw type, and product not only perfect heat-dissipating, rate of heat exchange is high, and lightweight, intensity is high, corrosion-resistant, long service life.
