Description
Affiliated technical field
The present invention relates to aluminium sheet production technology field, relate in particular to the production technology of producing the aluminium sheet be applicable to that the required aluminium shell product of punching out cosmetic bottle cap, perfume bottle cap, lipstick pipe box, eyebrow pencil cover etc. and electronics industry is required.
Background technology
Existing production is applicable to that the production technology of the aluminium sheet that the required aluminium shell product of punching out cosmetic bottle cap, lipstick pipe box, eyebrow pencil cover and electronics industry is required is a calendering technology, be about to raw material aluminium base and form the aluminium base again by between two cylinders of milling train by fusing refining strand, pressure by cylinder is pressed into certain thickness aluminium sheet (perhaps aluminum strip) with the aluminium base, again with aluminium sheet by being provided with the milling train of the littler cylinder in gap, roll and thinner aluminium sheet, the aluminium sheet that repeatedly needing to obtain thickness like this by the milling train calendering.
The shortcoming of above-mentioned prior art is: in the indwelling process of aluminium base before entering calendering technology, inevitable surface can contact with air and produce oxide layer, in calendering technology, this kind oxide layer can be mixed with the inner aluminium of aluminium base, and owing to calendering and broken, distortion, extend, produce phenomenons such as " Bark mark ", " mountain peak line ", " annual ring line " thus in the finished product surface of aluminum plate, cause surface smoothness low, color and luster is inhomogeneous.
Summary of the invention
The invention provides a kind of technique of preparing extrusion aluminum board, its purpose is to overcome the prior art shortcoming, a kind of production technology is provided, can produces phenomenon, even, the highly polished aluminium sheets of surface color such as " Bark mark ", " the mountain peak line " that can eliminate on the finished product aluminium sheet, " annual ring line ".
The technical solution adopted for the present invention to solve the technical problems is:
Technique of preparing extrusion aluminum board is characterized in that: comprise the steps:
(1): aluminium bar, mould, the ingot-containing tube preheating procedure of heating:
Aluminium bar: preheating in 2-5 hour in advance, 500 ℃ ± 100 ℃ of preheat temperatures;
Mould: preheating in 2-5 hour in advance, 450 ℃ ± 100 ℃ of preheat temperatures;
Ingot-containing tube: preheating in advance, 430 ℃ ± 100 ℃ of preheat temperatures;
(2): extrusion process: aluminium bar is inserted in the ingot-containing tube, the extruding aluminium bar, and aluminium sheet is extruded from the mould mouth;
(3): cut the packing aluminium sheet.
Above-mentioned basic steps, purpose are that making aluminum be easier to be overstock distortion by preheating is convenient to processing.Ingot-containing tube and mould get preheating can guarantee the maintenance of aluminium bar temperature in extrusion process.
Above-mentioned steps (2) can also add operation (2a) before: aluminium bar is inserted the preceding detected temperatures of ingot-containing tube, and temperature should reach more than 480 ℃.
Lower the temperature owing to several hrs after the aluminium bar preheating can be subjected to ambient influnence, therefore before extruding, guarantee certain temperature can guarantee that squeezing effect is unaffected.
Can insert operation (2b) afterwards in step (2): aluminium sheet excises the aluminium sheet rearward end after the mould mouth is all extruded.
Above-mentioned operation (2b) can replace with operation (2c): the rearward end of aluminium sheet is stayed in the ingot-containing tube, and excision aluminium sheet rearward end.
Above-mentioned steps can be replaced, and its purpose all is to guarantee end product quality with the main aluminium sheet rearward end amputation that is made of primary aluminum base surface oxide layer.
The above-mentioned aluminium trade mark that base adopts is 1070-1080.
The trade mark 1070,1080 grades all are the GB trade mark (seeing GB/T 3190-1996) high purity aluminum alloy, and the aluminum content height is fit to make the more excellent aluminium sheet of quality.
Above-mentioned ingot-containing tube is a hollow cylinder, cylindrical shell outside parcel insulation electrolysis stone, and cylindrical shell one end correspondence is provided with mould, and the corresponding tubular axis of mould place is provided with through hole, and the cylindrical shell other end is to there being passive power-actuated push rod.
Said structure is applicable to the use of this technology, can process qualified aluminium sheet effectively.
The usefulness of technique scheme is: adopt extrusion process processing aluminium sheet, the aluminium sheet that is extruded out from the mould mouth is to be made of the aluminium in the middle part of the aluminium base, cause the aluminium base surface oxide layer of " Bark mark ", " mountain peak line ", " annual ring line " to stay the last rear end of aluminium sheet just, excision is handled easily, and the most of surface of aluminum plate color and luster that processes is even, and is highly polished.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that extrusion process of the present invention uses
The specific embodiment
Below be most preferred embodiment of the present invention.
Brilliance board 1070 trade mark aluminium that the aluminium base selects for use Guizhou Aluminum Factory to produce, its composition following (percentage):
Al：99.7-99.8；Si：0.0515；Fe：0.1017；Cu：0.0010；Mn：0.0030；Mg：0.0014；Zn：0.0100；Ni：0.0025；Cr：0.0010；Pb：0.0012；Sn：0.0010；Ti：0.0111；B：0.001；Be：0.0010；Bi：0.0010；Na：0.0010；Sr：0.0010；Li：0.0010；V：0.0061；Zr：0.0049。In the fusion process, at the aluminium coolant-temperature gage during at 700 ℃-740 ℃, aluminium per ton add 0.3-0.5KG titanium boron fining agent (40%TI, 4%B).Guaranteed to improve the aluminium bar interior tissue, can increase substantially the final mechanical performance of product, improved intensity simultaneously, extensibility is improved the uniformity and the brightness of heat-tinting.
