铝面板构件钣金加工的实现

铝面板挂耳可用两种方法加工：一是整体式，在下料铝面板时先留下挂耳尺寸，然后在冲压时直接折弯而成，即与铝面板连成一体，而挂耳上的开孔在铝面板开角时一同加工出来；另一种是分离式，将直角铝型材（已先冲好孔）用抽芯铆钉加装在铝面板构件的浅槽边帮上。

铝面板挂耳可用两种方法加工：一是整体式，在下料铝面板时先留下挂耳尺寸，然后在冲压时直接折弯而成，即与铝面板连成一体，而挂耳上的开孔在铝面板开角时一同加工出来；另一种是分离式，将直角铝型材（已先冲好孔）用抽芯铆钉加装在铝面板构件的浅槽边帮上。

加强筋通常采用铝槽材或铝角材，加强筋的数量由铝面板构件的尺寸而定。

用闪光焊在铝面板的背面焊上螺栓（亦即种钉），把加强筋上的开孔插到螺栓上并再加垫片和弹簧垫圈，旋入螺帽固紧，再将加强筋的两端头部用抽芯铆钉铆接在铝面板构的浅槽边帮上。这样一来，铝面板就与加强筋构成一个整体。显然，加强筋的作用，一是提升铝面板构件的刚度，以增加抗风压性能，二是保证铝面板构件使用过程中的平直度，以免凹陷或变形。至此，铝面板构件的钣金加工就全部完成。

钣金加工在室温和不润滑的情况下进行。有些厂家是在引进的钣金生产线上连续完成下料、冲压、折边、焊接、种钉和打磨等各道工序的。

钣金加工对钣金密度的要求

可是高密度机架带来的好处是显而易见，至少可以获得较高的运算能力和可用度。另外一个挑战来自于成本(例如：烟雾报警器/平方英尺)，但是它并不会致使高密度产生明确的费用。此外，对较高密度给予预期的高水平监测将抵消上述不利因素。
