Flame cutting machine advancing mechanism for bending knife machining

The utility model relates to the technical field of flame cutting, in particular to a flame cutting machine advancing mechanism for bending knife machining, which can enable a device to automatically move and perform multi-angle cutting, replaces the traditional steps of scribing and the like, reduces manual operation, and improves the working efficiency and operability of the device. Comprising a connecting shaft, two advancing mechanisms and a cutting mechanism, the two advancing mechanisms are connected through the connecting shaft, and the cutting mechanism is installed on the connecting shaft; each advancing mechanism comprises a support, a first motor, a first bevel gear, a bidirectional lead screw, a second bevel gear, an inserting rod, a plurality of sliding bars and two moving mechanisms, the two ends of a connecting shaft are fixedly connected with the supports in the two advancing mechanisms correspondingly, two sliding grooves are formed in the lower end face of each support in a bilateral symmetr
