Laser-plasma composite cutting nozzle and cutting device

The utility model relates to the technology of cutting devices, and provides a laser-plasma composite cutting nozzle and a cutting device. An arc channel is arranged in the middle of the laser-plasma composite cutting nozzle, an annular gas collection chamber is arranged in the nozzle around the arc channel and communicated with the arc channel through an annular gas passage, the annular inner side of the gas passage is communicated with the arc channel, and the annular outer side of the gas passage is communicated with the annular gas collection chamber. And the auxiliary gas inlet channel is communicated with the outer side edge of the annular gas collection chamber and is used for tangentially feeding auxiliary gas. A laser-plasma composite cutting device comprises a nozzle. According to the nozzle, the cutting quality can be improved, the risk that the service life of an electrode is shortened due to the fact that active gas is used is reduced, and the cutting speed of metal plate materials can be increas
