鋁板生產(chǎn)廠家告訴你鋁板折彎后開裂怎么辦？
　　The aluminium plate manufacturer tells you what to do if the aluminium plate cracks after bending.
　　鋁板彎曲后開裂的幾個主要原因及注意事項:
　　Several main causes and precautions for cracking of aluminium sheet after bending:
　　1. 鋁板硬度
　　1. Hardness of Aluminum Plate
　　鋁板太硬，不易開裂。這就要求選擇優(yōu)質(zhì)的鋁板，主要是鋁合金和狀態(tài)鋁。通常1系列、3系列、5系列比較常用;6系列、7系列硬度過高，要做退火處理才能使O態(tài)良好彎曲。以及鋁的質(zhì)量。
　　Aluminum sheet is too hard to crack. This requires the selection of high quality aluminium sheets, mainly aluminium alloys and state aluminium. Usually, series 1, 3 and 5 are commonly used; Series 6 and 7 have too high hardness, so annealing treatment is needed to make the O state bend well. And the quality of aluminium.
　　2. 鋁板厚度
　　2. Thickness of Aluminum Plate
　　太厚的鋁板彎曲不好，我們要了解，盡量用薄一點的鋁板。
　　Too thick aluminium sheets do not bend well. We need to understand that we should try to use thinner aluminium sheets.
　　3.R角彎曲的大小
　　3. The Size of R Angle Bending
　　彎R角越大，說明成功率越高，所以盡量調(diào)整彎R角越大。
　　The bigger the bend R angle is, the higher the success rate is, so adjust the bend R angle as much as possible.
　　4. 鋁板紋理方向
　　4. Texture Direction of Aluminum Plate
　　彎曲方向應(yīng)垂直于鋁的紋理方向，而不是平行的。

                             
　　The bending direction should be perpendicular to the texture direction of aluminium, not parallel.
　　5. 鋁件在需要拉絲時，較好是先彎曲再拉出形狀，在工序允許的條件下，否則會增加彎曲和開裂的概率。
　　5. When drawing aluminium parts, it is better to bend first and then draw out the shape. If the process permits, otherwise it will increase the probability of bending and cracking.
　　,是較重要的國家,國家分為硬半硬,軟狀態(tài)(通常是軟狀態(tài)稱為O狀態(tài))并不是所有努力彎曲效應(yīng)基本行(鋁板是H18,段H19和H38所有困難)半硬狀態(tài)鋁板基本上可以彎曲(H24半剛性)O彎曲的狀態(tài)肯定是沒問題,但是因為太軟,基本上用這種狀態(tài)來折彎是比較少的，那么你應(yīng)該選擇純鋁或純鋁合金，鋁的硬度不是很高，有1100、1050、1060等。可推薦使用1100h26鋁合金硬度較好，可采用3003、3005、5052等半硬狀態(tài)即可。
　　First of all, the most important countries are divided into hard and semi-hard state, soft state (usually called O state) is not the basic line of bending effect (aluminum plate is H18, section H19 and H38 all difficulties) semi-hard state aluminum plate can basically bend (H24 semi-rigid) O bending state is certainly no problem, but because it is too soft, basically using this state to bend is relatively small, then you should. Choosing pure aluminium or pure aluminium alloy, the hardness of aluminium is not very high, there are 1100, 1050, 1060 and so on. It can be recommended to use 1100h26 aluminium alloy with better hardness. It can use 3003, 3005, 5052 and other semi-hard states.
　　具體情況建議樣品來確定,如果在6061年,2024年,7075年,由于硬度太高,特別是T6狀態(tài),更應(yīng)該彎曲,除非熱量褶皺,優(yōu)質(zhì)的區(qū)別是鋁和氧化鋁性能的質(zhì)量差,寬容,表面效果,水晶的準確性和區(qū)分的均勻穩(wěn)定,彎曲的效果有些不同于孤獨。
　　Specific circumstances suggest that samples should be determined if in 6061, 2024, 7075, due to the high hardness, especially in T6 state, they should be bent. Except for thermal folds, the difference of high quality is poor quality of aluminium and alumina, tolerance, surface effect, crystal accuracy and uniform stability of differentiation, and the effect of bending is somewhat different from that of loneliness.
