Double-head laser cutting system

The utility model relates to the technical field of laser cutting machines, in particular to a double-head laser cutting system which comprises a workbench, a cross beam, a first moving device, a longitudinal beam, a second moving device, two sets of laser cutting heads and two sets of laser modules. The output end of a first moving device on the cross beam is connected with the laser cutting head, each laser module comprises a laser tube, a primary reflector, a secondary reflector and a laser head reflector which are sequentially arranged along a light path, and the direction of laser emitted to the secondary reflector is perpendicular to the direction of laser emitted out of the secondary reflector. The primary reflector and the secondary reflector are arranged on the laser head reflector, the direction of laser reflected by the secondary reflector is parallel to the cross beam, incidence points and incidence angles of the laser on the primary reflector, the secondary reflector and the laser head reflector
