Description

Technical Field

[0001] The utility model relates to the technical field of motor stator processing, in particular to a motor stator twist end expanding machine. Background Art

[0002] As the name suggests, flat wire motors use flat copper wire in their stator windings. The windings are first made into a hairpin-like shape, inserted into the stator slots, and then the ends of the hairpins are welded at the other end. During the processing of flat copper wire motors, the twisted ends of the stator's flat copper wires need to be expanded. During the expanding process, the copper wires need to be expanded outward. In order to prevent the copper wires from breaking the insulating paper when they expand, a protective mechanism for protecting the insulating paper needs to be installed. However, existing expanding machines all manually install limit mechanisms, which is time-consuming and labor-intensive. In addition, during the closing process, the copper wires have an upward force relative to the iron core and the insulating paper, which causes the insulating paper to be pulled when the copper wires move upward, affecting the processing quality.
