Combined tool for carbon fiber aramid paper honeycomb sandwich composite board

The invention discloses a combined tool for a carbon fiber aramid paper honeycomb sandwich composite board. The combined tool for the carbon fiber aramid paper honeycomb sandwich composite board comprises a tool bar and a tool bit, wherein the tool bit comprises a first cutting component and a plurality of second cutting components, the first cutting component is used for machining an upper carbonfiber layer and a lower carbon fiber layer of the composite board, and comprises an upper tool disc and a lower tool disc, a plurality of first spiral grooves are formed in the periphery of each tooldisc correspondingly, and first tool teeth of the tool discs are formed between every two adjacent first spiral grooves; the plurality of second cutting components are used for machining an aramid paper honeycomb sandwich layer of the composite board, and the second cutting components are stacked together; each second cutting component comprises two blades which are adjacent to each other up anddown, and a plurality of second spiral grooves are formed in the periphery of each blade correspondingly, and second tool teeth of each blade are formed between every two adjacent second spiral grooves; the second cutting components are located between the two tool discs, and the cutting directions of the first tool teeth of the tool discs and the cutting directions of the second tool teeth of each blade are consistent. According to the combined tool for the carbon fiber aramid paper honeycomb sandwich composite board, synchronous cutting of carbon fiber composite material and aramid paper honeycomb core material can be realized, the machining quality and the machining efficiency are improved, and the service life of the tool is prolonged.
