硬质合金化纤切断刀刃口角度对耐用度的影响

Influence of Edge Angle on Endurance of Carbide Cutter for Chemical Fiber

在自制的小型实验性短纤维切断装置上,通过模拟涤纶短纤维的切割加工过程,对化纤切断刀刃口角度与耐用度之间的关系进行了研究。结果表明,刃口角度过小或过大都会影响切断刀的耐用度,在一定生产条件下存在一个最佳的刃口角度。

The relationship between endurance of hard alloy cutter edge and the edge angle is investigated through simulating the process of cutting polyester staple with a self-made miniature fiber cutting equipment. The result shows that the edge angle has an important effect on the cutter blade endurance in the course of fiber cutting. It will decrease the cutter blade＇s endurance serionsly, when the angle is very small or large.
