This utility model relates to a swing-assisted molybdenum wire feeding mechanism. It solves the technical problems such as molybdenum wire curling that occur during the molybdenum wire feeding process in existing wire EDM machines. It includes a machine bed, with a swing column on one side. A horizontally positioned upper cantilever above the machine bed is connected to the swing column. A molybdenum wire feeding structure, parallel to the upper cantilever, is located on the upper side of the upper cantilever. A wire-drawing clamp assembly is movably mounted within the molybdenum wire feeding structure. The wire-drawing clamp assembly moves axially along the length of the molybdenum wire feeding structure via a wire-drawing drive mechanism. The advantages are: automated wire feeding; a drive motor provides power, which is transmitted to the transmission slider via a synchronous belt and drive connection assembly, ultimately driving the wire-drawing clamp assembly to automatically feed the molybdenum wire. This eliminates the need for manual dragging of the molybdenum wire, reducing operator workload and avoiding problems such as wire misalignment and damage caused by manual operation, thus improving wire feeding efficiency.
