铝板生产厂家告诉你铝板折弯后开裂怎么办？
　　The aluminium plate manufacturer tells you what to do if the aluminium plate cracks after bending.
　　铝板弯曲后开裂的几个主要原因及注意事项:
　　Several main causes and precautions for cracking of aluminium sheet after bending:
　　1. 铝板硬度
　　1. Hardness of Aluminum Plate
　　铝板太硬，不易开裂。这就要求选择优质的铝板，主要是铝合金和状态铝。通常1系列、3系列、5系列比较常用;6系列、7系列硬度过高，要做退火处理才能使O态良好弯曲。以及铝的质量。
　　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. 铝板厚度
　　2. Thickness of Aluminum Plate
　　太厚的铝板弯曲不好，我们要了解，尽量用薄一点的铝板。
　　Too thick aluminium sheets do not bend well. We need to understand that we should try to use thinner aluminium sheets.
　　3.R角弯曲的大小
　　3. The Size of R Angle Bending
　　弯R角越大，说明成功率越高，所以尽量调整弯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. 铝板纹理方向
　　4. Texture Direction of Aluminum Plate
　　弯曲方向应垂直于铝的纹理方向，而不是平行的。

                             
　　The bending direction should be perpendicular to the texture direction of aluminium, not parallel.
　　5. 铝件在需要拉丝时，较好是先弯曲再拉出形状，在工序允许的条件下，否则会增加弯曲和开裂的概率。
　　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.
　　,是较重要的国家,国家分为硬半硬,软状态(通常是软状态称为O状态)并不是所有努力弯曲效应基本行(铝板是H18,段H19和H38所有困难)半硬状态铝板基本上可以弯曲(H24半刚性)O弯曲的状态肯定是没问题,但是因为太软,基本上用这种状态来折弯是比较少的，那么你应该选择纯铝或纯铝合金，铝的硬度不是很高，有1100、1050、1060等。可推荐使用1100h26铝合金硬度较好，可采用3003、3005、5052等半硬状态即可。
　　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.
　　具体情况建议样品来确定,如果在6061年,2024年,7075年,由于硬度太高,特别是T6状态,更应该弯曲,除非热量褶皱,优质的区别是铝和氧化铝性能的质量差,宽容,表面效果,水晶的准确性和区分的均匀稳定,弯曲的效果有些不同于孤独。
　　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.
