[0001] The invention relates to an armature head cutting device. Background technique
[0002] In the prior art, an armature is composed of an armature body and an enameled wire embedded in an armature slot of the armature body. During the production process, the enameled wire is first embedded in the armature slot with a margin, and then the excess enameled wire joint is cut off with a cutter. The disadvantages of this treatment method are: 1. Since the enameled wire is relatively soft, the cutter generally cuts the enameled wire joint in the form of extrusion, which tends to make the enameled wire tilt radially, resulting in incomplete cutting, and the enameled wire is at the commutator. It is easy to form a bow shape, which will affect the subsequent process, resulting in a large void rate during spot welding and reducing the welding strength. If the enameled wire is welded in the armature slot before cutting, although it can prevent deformation during c...
