铝箔分切机碟形刀结构优化

Structure optimization of dish knife in the aluminum foil slitting machine

铝箔分切机在分切过程中易出现边部毛刺、翘边问题,为提高铝箔分切精度,分析了现有蝶形刀和刀座结构。现有刀座结构在加工过程中难以保证圆度和端面跳动,碟形刀片的定位精度低,在分切过程中左右摆动。为此,提出对刀座结构进行优化,避免刀座径向开槽。优化后的碟形刀整体刚性好、精度高。试验表明,优化后的蝶形刀在分切过程中铝箔边部未出现毛刺、翘边,有效提高了分切精度。

Aiming at the burr and warp in aluminum foil slitting process and improving the accuracy of aluminum foil cutting,it analyzes the structure of the existing dish knife and knife holder. The knife holder structure makes it difficult to guarantee the precision of the knife holder in the machining process and reduce the positioning accuracy of the dish knife blade. It proposes the knife holder structure optimization method. This design avoids radial grooving in knife holder,improves the overall rigidity and precision. The experiment shows that the optimization of the dish knife in the cutting process of aluminum foil edge does not appear burr and warp.
