Abstract
The invention relates to a production method of an aluminum alloy heat radiator sectional material with a helical fin. A guide disc is fixed at the outlet end of a lower mould, a rotating device with a rotating disc is arranged outside the guide disc, a traction device with a special clamp is arranged outside the rotating device, a walking track is arranged at the lower part of the traction device, an aluminum ingot is strongly impulsed by an extruding machine to enter the lower mould through an upper mould tap hole and then is extruded from a mould hole of the lower mould to pass through the guide disc; the aluminum ingot enters the rotating device and the traction device through the rotating disc after being changed into the sectional material, the rotating disc rotates together with the sectional material in the rotating disc under the drive of a motor; because the guide disc is fixed, the sectional material between the guide disc and the rotating disc generates helical plastic deformation, and is guided to be continuously prolonged along the walking track with the traction device, the rotating disc rotates, and the sectional material between the guide disc and the rotating disc continuously generates helical plastic deformation, thus the aluminum alloy heat radiator sectional material with the helical fin is produced.
Description
Technical field
The present invention relates to a kind of aluminium alloy radiator sectional material with fin of extrusion modling, especially a kind of production method of the aluminium alloy radiator sectional material with spiral fins.
Background technology
Radiator is the terminal device of Home Heating, by heat conduction, radiation, convection current, heat is dispelled the heat out, allows the temperature in room get a promotion.Obtained the approval of most domestic heatings at radiator industry radiator heating now.Radiator heating is high-efficiency comfortable not only, and the live and work that extremely meets the modern is accustomed to, so increasing people starts to select radiator heating, the nearly people over half choosing period of time radiator that heats in the winter time in the whole nation, and along with the development of building trade, the lifting of construction area, the continuous expansion of heating zone, the expansion that also will keep of the demand of radiator.Traditional heating radiator is with cast-iron radiator, panel radiator, and not only environmental pollution is serious during fabrication, and the thermal efficiency is low, it is slow to conduct heat, outward appearance is coarse and crude, heavy, progressively is eliminated.A kind of Al-alloy heat exchanger that adopts extrusion modling is due to lightweight, handsome in appearance, heat exchange efficiency is high and selected in a large number.But the radiating fin on these heat-exchange tubes is linear pattern, with the screw type radiating fin, compare, although technique is simple, there is the problem that affects rate of heat exchange.But the shaped material of radiator of screw type radiating fin, due to complex manufacturing, is not found the section bar of extrusion modling so far.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of aluminium alloy radiator sectional material with spiral fins, when completing section bar extrusion, traction, become screw type by its linear pattern fin machining, 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 that draw-gear forms, inside and outside radiating tube, all the port of export with the extrusion die counterdie of linear pattern fin is fixed a positioning disk, the outside of positioning disk is provided with the 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, be provided with rotating section bar special fixture 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, enter counterdie through the patrix tap hole, then from the nib of counterdie, extrude, pass through positioning disk, become inside and outside pipe all with the section bar of linear pattern radiating fin, under extruder continues to promote, the head of section bar enters tumbler through rolling disc, enter draw-gear from the rear portion of tumbler again, and the clamp clamps be arranged on draw-gear is locked, the linear fin of section bar surrounding is along with in some the fin grooves of answering in contrast that enter 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 inside and outside fin on section bar produces the screw type plastic deformation, along with draw-gear guiding section bar constantly extends along its walking track, rolling disc is along with rotation, section bar between positioning disk and rolling disc constantly produces the 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 special fixture is identical and synchronous with the rolling disc revolution on tumbler.
Device structure of the present invention is reasonable, simple applicable, the linear pattern fin machining on shaped material of radiator can be become to 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.
