Description
Technical field
The present invention relates to the production of aluminium section bar, particularly a kind of al profile extrusion line.
Background technology
Aluminium section bar production is by the rear extrusion modling on fixed mould of aluminium bar heating.All there are the problems such as efficient is low, intensification is slow, heating is inhomogeneous in main fuel oil, combustion gas or the electric radiation of adopting of the aluminium bar heating of using on the existing al profile extrusion line.Because the restriction of these mode of heatings is so that the heating system of aluminium bar is separated with extrusion system on the al profile extrusion line.Aluminium bar heats in heating furnace first, then cuts off to be put on the mould and pushes.Because the aluminium bar after the heating all has certain heat loss in carrying and extrusion process, the temperature of aluminium bar heating need to be higher than the required temperature of extruding, causes certain energy waste.
Summary of the invention
In order to overcome the above problems, the present invention proposes a kind of apparatus and method of al profile extrusion line, its technical scheme is: aluminium bar heating system and extrusion system are integrated, propulsive mechanism is advanced to aluminium bar in the insulating sleeve before the extrusion die, the peripheral induction coil that twines of insulating sleeve carries out eddy-current heating to aluminium bar, reaches heating and pushes the effect of carrying out synchronously.
The concrete device of a kind of al profile extrusion line that the present invention proposes is as follows:
Described al profile extrusion line device mainly comprises pedestal, propulsive mechanism, mould, slide rail, insulating sleeve, induction coil, intermediate frequency power supply, temperature detection part and temperature controller etc.
Propulsive mechanism, mould, slide rail, insulating sleeve are installed on the same pedestal.Before described insulating sleeve is placed on mould, its peripheral induction coil that twines.Described induction coil links to each other with intermediate frequency power supply.Can place aluminium bar on the described slide rail.Described propulsive mechanism comprises propelling driver and pushing ram, and the promotion aluminium bar moves to mould at described slide rail and pushes.The diameter of described pushing ram is identical with aluminium bar, than the little 2～20mm of internal diameter of described insulating sleeve.
Described insulating sleeve length l is identical with described induction coil, determines to temperature required time t and the pace v of described pushing ram according to the aluminium bar eddy-current heating, and it determines that formula is l=vt.
In described insulating sleeve exit a temperature detection part is set, described temperature detection part links to each other with temperature controller.Described temperature controller can be controlled described propelling driver.
The concrete grammar of a kind of aluminium section bar production process that the present invention proposes is as follows:
(1) aluminium bar is placed on the described slide rail, starts eddy-current heating and described propelling driver, advance by the speed drive pushing ram of setting, aluminium bar is advanced in the described induction coil heats.
(2) temperature after described insulating sleeve exit uses described temperature detection part to the aluminium bar heating detects.If the temperature after the described insulating sleeve exit aluminium bar heating is lower than the required temperature of heating, stop described pushing ram and advance, move on after temperature required until aluminium bar reaches, and reduce the pace of described pushing ram.If the temperature after the heating of described insulating sleeve exit aluminium bar is higher than the required temperature of heating, improve the pace of described pushing ram.
(3) can produce some frictional heats because aluminium bar pushes in mould, the temperature after the heating of described insulating sleeve exit aluminium bar can be than pushing low 10～50 ℃ of required temperature.
Useful technique effect of the present invention has:
A kind of al profile extrusion line provided by the invention, heating system and extrusion system are integrated, reduce widely the space of al profile extrusion line, improve the automated production degree of Extrusion Process of Aluminum Alloy Profile, can effectively control the quality that aluminium section bar is produced.Aluminium bar uses eddy-current heating and insulating sleeve insulation, homogeneous heating, and heat time heating time is short, greatly improves the efficiency of heating surface, and heating-up temperature is lower than the required temperature of extruding, and energy savings does not have exhaust emissions, environmental protection.
