A three-dimensional wound core transformer winding machine

Abstract

The invention discloses a coil winding machine for a stereoscopic wound iron core transformer. The coil winding machine for the stereoscopic wound iron core transformer comprises a machine base, a clamping mechanism, a transmission mechanism and a coil winding supporting mechanism, wherein the clamping mechanism, the transmission mechanism and the coil winding supporting mechanism are arranged on the machine base, an auxiliary supporting mechanism is further arranged on the machine base and located below the clamping mechanism, and the auxiliary supporting mechanism can jack up and support a stereoscopic wound iron core on the clamping mechanism through regulation operations. On the premise that normal coil winding and overturning operations are not affected, the coil winding machine for the stereoscopic wound iron core transformer can stably, firmly and reliably jack up and support the stereoscopic wound iron core hung and assembled on the clamping mechanism, further shares the load of the stereoscopic wound iron core borne by the clamping mechanism, is favorable for lowering the requirement for the structural strength of the clamping mechanism, and then lowers the manufacturing cost of the coil winding machine. Besides, the coil winding machine for the stereoscopic wound iron core transformer can achieve synchronous winding of foil type coil copper foil of a cylinder structure and layer insulation materials, lowers the winding difficulty of the coil and the processing difficulty of leads, and improves coil winding efficiency.

Description

technical field [0001] The invention relates to winding equipment for transformer coils, in particular to a three-dimensional winding core transformer winding machine. Background technique [0002] The core of the three-dimensional wound core transformer is a triangular three-dimensional structure composed of three wound cores with the same geometric size and single frame. Compared with the planar wound core transformer, it has excellent performances such as complete symmetry of the three-phase magnetic circuit, remarkable power saving effect, greatly reduced noise, stronger heat dissipation and overload capacity, compact structure, small volume, and low production cost. Widely welcomed by users. However, since the core structure of the three-dimensional wound core transformer is completely different from that of the planar wound core transformer, the winding machine of the planar wound core transformer cannot be used for the winding operation of the three-dimensional wound...

Problems solved by technology

However, when the large-capacity coil adopts a cylindrical structure, it is difficult to wind the coil and handle the lead wires during the winding process. Therefore, it is generally suitable to use a foil coil structure. The winding of the foil coil requires a layer of insulating material At present, there has not been a three-dimensional wound core transformer winding machine in which copper foil and layer insulating material are wound synchronously in the prior art.
