鋁卷加工工藝要注意體現(xiàn)哪些效果?

來源:http://www.kangyanghua.com/ 發(fā)布時間:2021-07-06

硅對硬質合金有腐蝕效果。雖然一般將超越12%Si的鋁合金稱為高硅鋁合金,彩涂鋁卷引薦運用金剛石刀具,但這不是肯定的,硅含量逐步增多對刀具的損壞力也逐步加大。因此有些廠商在硅含量超越8%時就引薦運用金剛石刀具。
Silicon has corrosive effect on cemented carbide. Although the aluminum alloy with more than 12% Si is generally called high silicon aluminum alloy, and the diamond tool is recommended for color coated aluminum coil, this is not certain. The damage force of the tool is gradually increased with the increase of silicon content. Therefore, some manufacturers recommend the use of diamond tools when the silicon content exceeds 8%.
硅含量在8%-12%之間的鋁合金是一個過渡區(qū)間,既可以運用一般硬質合金,也可以運用金剛石刀具。但運用硬質合金應運用經PVD(物理鍍層)辦法、不含鋁元素的、膜層厚度較小的刀具。
The aluminum alloy with silicon content between 8% and 12% is a transition zone, which can use both general cemented carbide and diamond tools. However, the use of cemented carbide should be PVD (physical coating) method, does not contain aluminum, the film thickness of the tool is small.
由于PVD辦法和小的膜層厚度使刀具堅持較尖利的切削刃成為可能(否則為避免膜層在刃口處反常長大需要對刃口進行足夠的鈍化,切鋁合金就會不夠尖利),而膜層資料含鋁可能使刀片膜層與工件資料發(fā)作親合效果而損壞膜層與刀具基體的結合。由于超硬鍍層多為鋁、氮、鈦三者的化合物,可能會因硬質合金基體隨膜層剝落時少數(shù)剝落造成崩刃。
PVD method and small film thickness make it possible for the tool to stick to a sharp cutting edge (otherwise, in order to avoid the abnormal growth of the film at the edge, it is necessary to passivate the edge sufficiently, and the cutting of aluminum alloy will not be sharp enough), and the film data containing aluminum may cause the affinity effect between the blade film and the workpiece data and damage the combination between the film and the tool matrix. Because the superhard coating is mostly composed of aluminum, nitrogen and titanium, the edge may collapse due to a small amount of peeling off of cemented carbide substrate with the film peeling off.

建議運用下列三類刀具之一:
It is recommended to use one of the following three types of tools:
1.不鍍層的超細顆粒硬質合金刀具
1. Uncoated ultrafine cemented carbide tools
2.帶未含鋁鍍層(PVD)辦法的硬質合金刀具,如鍍TiN、TiC等
2. Cemented carbide tools without aluminum coating (PVD), such as tin, tic, etc
3.用金剛石刀具
3. Using diamond tools
刀具的容屑空間要大,一般建議用2齒,前角、后角要大(如12°-14°,包含端齒后角)。
It is generally recommended to use 2 teeth, with large rake angle and rake angle (e.g. 12 ° to 14 ° including rake angle of end teeth).
假如只是一般銑面,可以用45°主偏角的可轉位面銑刀,配用專門加工鋁合金的刀片,應該效果更好。
If only general milling face, can use 45 ° main deflection angle of indexable face milling cutter, with special processing aluminum alloy blade, the effect should be better.
氧化鋁在1808年在實驗室使用電解還成為鋁材,于1884年即被作為建筑資料運用在華盛頓紀念碑尖頂上至今;鋁材參加各種金屬元素合成的鋁合金資料已被建筑工業(yè)廣泛應用在各環(huán)節(jié)上。 鋁合金常用板材厚度:高檔金屬屋面(和幕墻)體系的一般為0.8-1.2mm(而傳統(tǒng)的一般要≥2.5mm).
Alumina was used in the laboratory in 1808 and became aluminum material by electrolysis. In 1884, it was used as building materials on the spire of Washington Monument; The information of aluminum alloy synthesized by various metal elements has been widely used in all aspects of the construction industry. Thickness of common aluminum alloy sheets: the thickness of high-grade metal roof (and curtain wall) system is generally 0.8-1.2mm (while the traditional thickness is generally ≥ 2.5mm)
