Anti-sputtering structure of numerical control electric spark forming machine

The anti-sputtering structure of the numerical control electric spark forming machine comprises a base, a fence fixedly connected to the top of the base and an electric spark machining assembly arranged on the top of the base, and the front face of the fence is fixedly connected with a connecting block. In the moving process of the output end of the electric spark machining assembly, the transmission structure is used for driving the bevel gear to rotate, the bevel gear transmits power and drives the protective door to swing through the shaft rod, and when the electric spark machining assembly moves to the maximum stroke, the rubber mat on the back face of the protective door makes contact with the fence and completes protective sealing of the fence. Sparks generated in the machining process of the electric spark machining assembly can be shielded by the fence and the protective door, the influence of the sparks on the surrounding environment is reduced, and the problems that an opening mode of an existing nu
