关于不同厚度的济南铝板折弯度的问题

最近经常碰到客户在买济南铝板时会问关于铝材折弯的问题,比如3mm的铝板折弯的时候该系数是多少?该用哪些刀?5mm厚的铝板折弯系数是多少?铝板折弯时为什么会开裂?铝板折弯180度时开裂的原因?
Recently often encountered customers in the purchase of Ji'nan aluminum plate will ask about the aluminum bending problems, such as the 3mm aluminum plate bending time the coefficient is how much? What kind of knife to use 5mm thick aluminum plate bending coefficient is how much? When the aluminum plate bending why will crack the aluminum plate bending 180 degrees when the reasons for cracking?

1.折弯的边与铝板的轧制方向平行,这样很容易开裂,将折弯方向转90度。Bending edge and aluminum plate in parallel, so it is easy to crack, bending the direction of 90 degrees.

2.180度折弯角度太多,要大于最小折弯半径,一般折弯半径为板厚的1.5倍。180 degree bending angle is too much, should be larger than the minimum bending radius, the general bending radius is 1.5 times the thickness of the plate.

3.材料的原因,用有的铝板是合金,韧性没有纯铝铝板好,易开裂。The reasons for the material, with some aluminum alloy, toughness is not pure aluminum, easy to crack. 

4.板材厚度太厚,折弯180度超出了材料的弯曲极限。The thickness of the plate is too thick, bending 180 degrees beyond the bending limit of the material.

其实济南铝板折弯系数是有规律的,一般是铝板厚度的0.8倍,比如3mm,铝板折弯系数是2.4,5mm铝板折弯系数是4.刀的话一般用尖刀为佳,用直剑刀压力太大,铝板容易有裂纹。
