Abstract

The invention provides an embedded copper busbar wave winding coil forming device, which comprises an end forming device and a straight line edge bending device, and is characterized in that the end forming device comprises an end clamping device, an end arc jacking device and straight line edge clamping devices, the end clamping device, the end arc jacking device and the straight line edge clamping device are sequentially connected to the two ends of the coil from outside to inside, and the straight line edge bending device is arranged between the straight line edge clamping devices. The device has the advantages of consistent shape, accurate size, accurate coil span, stable and reliable product quality, reduced labor intensity, improved production efficiency, shortened process time, reduced manufacturing cost and the like.

Description

technical field [0001] The invention relates to a motor coil forming process, in particular to an embedded copper bus wave winding coil forming device. Background technique [0002] In the YR wound motor, the rotor winding usually adopts a wave winding structure. When the three-phase coils are connected in a star shape and the neutral point and the phase lead-out line are not at the same end, a layer-up coil (also called a layer-jump coil) To realize the series connection between the poles in each phase. The forming methods of the wave winding copper busbar coil include manual knocking, mold knocking and equipment forming. The scope of application of the manual method is narrow, generally without insulation pre-forming, the other end of the plug-in structure needs to be knocked on the iron core with a simple tool, limited by the operating space, it is difficult to guarantee the shape consistency of the end arc, and it is easy to damage the insulation , the size is inaccura...
