Description

Technical Field

[0002] As the name implies, a flat wire motor uses flat copper wire in its stator winding. The winding is first made into a shape similar to a hairpin and inserted into the stator slot, and then the end of the hairpin is welded at the other end. When processing a flat copper wire motor, the tail of the flat copper wire of the stator needs to be cut flat. After the tail is cut flat, the next stator manufacturing process is end welding, and end welding requires a tail positioning tool. However, the cutting tool of the existing cutting device is incompatible with the subsequent welding positioning tool. The operating procedure is to manually cut the tail of the flat copper wire on the cutting tool, manually remove the cutting tool, and then install the welding tool. This manual operation method results in high manual labor intensity, and the cut surface of the flat copper wire is uneven, the blade is rough and has burrs, and at the same time, the rebound of the copper wire when the tool is replaced affects the tool positioning accuracy, thereby reducing the processing efficiency.
