Abstract
The invention belongs to the field of motor production and manufacturing and particularly relates to a wire cutting device of a stator winding machine. The wire cutting device comprises a fixed base block and a pressing block. A cutter is disposed on the base block. The pressing block moves in a reciprocating manner and is used for dragging an enameled wire to the cutter for cutting and tightly pressing the enameled wire to the base block. The moving direction of the pressing block is parallel with pointing direction of the edge of the cutter. A groove directly facing the cuter is formed in the pressing block, and cutting is completed by the meshing and separation of the cutter and the groove. The wire cutting device has the advantages that manual wire cutting by a worker after plastic package stator winding is not needed, the worker does not need to pull the wire during winding of the next stator, and the worker does not need to manually rewinding the loosened wire after plastic package stator winding is completed.
