通过对圆顶翅片散热带成形特点的分析,利用滚切成型原理开发出一种高效率、高精度、快速设计的翅片滚刀设计方法,并对滚刀的设计理论及成型原理进行阐述,以一种类型翅片的刀具为例进行滚刀的设计建模,经ANSYS仿真从而验证了该设计的正确性。 Based on the analysis of forming characteristics of the cooling fin of the dome fin, a design method of finned hob with high efficiency, high precision and rapid design was developed by using the principle of hobbing and forming. The design theory and forming principle Elaborated on a type of fin cutter as an example of hob design modeling, ANSYS simulation to verify the correctness of the design.
