Abstract
The present invention is one machining process of shapes for roller shutter. The machining process of the shapes includes melting aluminum ingot at 750 deg.c into molten aluminum, cooling into aluminum rod, extruding at 460 deg.c into shutter leaf shapes and guide canal shapes, fast cooling to 200 deg.c and maintaining at 200 deg.c for 2.9-32 hr, quenching, acid and alkali processing, and oxidizing to color or in oxidizing pool. The product has high strength, high hardness, less deformation, less rust, high smoothness and long service life.
Description
The invention belongs to the architectural shape manufacture field, specifically is a kind of processing method of shapes for roller shutter.
In the prior art, shapes for roller shutter adopts aluminum alloy materials to make mostly, and the processing of aluminium alloys shapes for roller shutter is the production method that adopts the crawler belt rolling-type, the aluminium alloys shapes for roller shutter intensity that this method processes is low, and difference of hardness is yielding, easily get rusty, fineness is poor, and application life is short.
The objective of the invention is in order to overcome the defective of prior art, provide a kind of product strength that makes to improve, hardness is good, and deformation resistance is good, is difficult for getting rusty, and fineness is good, the processing method of the shapes for roller shutter of long service life.
The objective of the invention is to realize by following technical proposals.
Technical scheme of the present invention is that aluminium ingot is melted into aluminium water under 750 ℃ ± 5 ℃, be cooled to aluminium bar then, under 460 ℃ ± 5 ℃ high temperature, be squeezed into the door sheet section bar or the guide groove section bar of rolling door again, cool off fast in 200 ℃ ± 5 ℃ and keep down section bar being quenched in 2.9～3.2 hours, successively heat-tinting promptly gets product in the oxidation pond with inserting after sour, the alkali treatment again.
As mentioned above, the processing of the aluminium alloys shapes for roller shutter of prior art is the production method that adopts the crawler belt rolling-type, and these methods adopted many years and nobody's breakthrough so far, make its product can't be suitable for the New Times people to product quality, outward appearance, the new demand of performance etc., technical scheme of the present invention overcome prior art to the processing of shapes for roller shutter can only adopt the processing of crawler belt rolling-type prejudice, adopt and melt, cooling, the high temperature extruding, quench, acid, alkali treatment, technologies such as heat-tinting, make products obtained therefrom overcome the defective of prior art, the product strength height that provides, hardness is good, deformation resistance is good, be difficult for getting rusty, fineness is good, long service life, little with the abrasion of door sheet as guide groove, the adhesive tape of guide groove is changed inconvenience.Shapes for roller shutter of the present invention comprises the door sheet section bar of rolling door, guide groove section bar and other section bar of rolling door.Method of the present invention also can adapt to the processing of other aluminium alloy extrusions.
Be embodiments of the invention below, the present invention is not limited only to described embodiment.
Embodiment one
Get 100 kilograms of aluminium ingots; insert in the thawing furnace; under 750 ℃ ± 5 ℃, be melted into aluminium water; pour out then and in mould, be cooled to aluminium bar; being heated to 460 ℃ ± 5 ℃ again makes aluminium bar softening; with 800 tons extruders it is squeezed into the door sheet section bar of rolling door; cool off rapidly in 200 ℃ ± 5 ℃ and keep down section bar being quenched in 3.1 hours; again successively with inserting heat-tinting in the oxidation pond after acid, the alkali treatment so that product increase layer protecting film, products obtained therefrom intensity height, hardness is good; deformation resistance is good; be difficult for getting rusty, fineness is good, long service life.
Embodiment two
Get 150 kilograms of aluminium ingots; insert in the thawing furnace; under 750 ℃, be melted into aluminium water; pour out then and in mould, be cooled to aluminium bar; being heated to 460 ℃ again makes aluminium bar softening; with 1000 tons extruders it is squeezed into the door sheet section bar of rolling door; cool off rapidly in 200 ℃ of maintenances and section bar was quenched in 3 hours, more successively with inserting heat-tinting in the oxidation pond after acid, the alkali treatment so that product increases layer protecting film, products obtained therefrom intensity height; hardness is good; deformation resistance is good, is difficult for getting rusty, and fineness is good; long service life, its product cross section structural representation as shown in Figure 1.
Embodiment three
Get 200 kilograms of aluminium ingots; insert in the thawing furnace; under 750 ℃ ± 5 ℃, be melted into aluminium water; pour out then and in mould, be cooled to aluminium bar; being heated to 460 ℃ ± 5 ℃ again makes aluminium bar softening; with 1000 tons extruders it is squeezed into the guide groove section bar of rolling door; cool off rapidly in 200 ℃ ± 5 ℃ and keep section bar being quenched in 3 hours priority acid again; insert heat-tinting in the oxidation pond after the alkali treatment so that product increases layer protecting film, products obtained therefrom intensity height; hardness is good; deformation resistance is good, is difficult for getting rusty, and fineness is good; long service life, its product cross section structural representation is shown in accompanying drawing 2～6.
Claims (2)
1. the processing method of shapes for roller shutter, be that aluminium ingot is melted into aluminium water under 750 ℃ ± 5 ℃, be cooled to aluminium bar then, under 460 ℃ ± 5 ℃ high temperature, be squeezed into the door sheet section bar or the guide groove section bar of rolling door again, cool off fast in 200 ℃ ± 5 ℃ and keep down section bar being quenched in 2.9～3.2 hours, successively heat-tinting promptly gets product in the oxidation pond with inserting after sour, the alkali treatment again.
2, the rolling door guide groove section bar of the processing method gained of shapes for roller shutter according to claim 1 and roller shutter every sheet section bar product.
