The invention discloses an electric device production device which comprises a bearing mechanism for placing a
magnetic core and a winding mechanism for winding the
magnetic core, the bearing mechanism comprises a driving part, the driving part drives the
magnetic core to rotate in the horizontal direction, the bearing mechanism further comprises a
diameter changing part, an adjusting part and a speed adjusting part which are sequentially connected, the
diameter changing part abuts against the surface of the magnetic core, and the speed adjusting part abuts against the surface of the magnetic core. According to the electric device production device, as the number of
layers of
copper wires on the surface of the magnetic core is increased, the
copper wires on the surface of the magnetic core extrude the variable-
diameter part to be away from the magnetic core in the vertical direction, the variable-diameter part drives the adjusting part to act, the adjusting part adjusts the speed adjusting part to be switched to a low-speed gear, and the horizontal
moving speed of the magnetic core driven by the driving part is slowed down; the winding speed of the
copper wires on the surface of the magnetic core is matched with the feeding speed of the magnetic core, the situation that the copper wires on the outer ring of the magnetic core are arranged loosely due to the fact that the
moving speed of the magnetic core is too high is avoided, and therefore the winding quality of the copper wires on the surface of the magnetic core is improved.
