Abstract
A method of manufacturing a stator core is disclosed. The method includes advancing a blank at each of a plurality of press cycles to form a segment at each of the press cycles and shaping the segments. Shaping the segments further includes activating a tooth punch, activating a mounting-ear punch, and activating an joint punch. The method also includes separating the segments from the blank.
Claims13
A method of manufacturing a stator core, comprising:
- advancing a blank at each of a plurality of press cycles, wherein each of the press cycles forms a segment;
- shaping the segments, wherein shaping the segments includes:
- activating a first tooth punch according to a first schedule, wherein the first tooth punch has a first tooth profile;
- activating a second tooth punch according to a second schedule, wherein the second tooth punch has a second tooth profile different from the first tooth profile, such that the segments have asymmetric teeth;
- activating a mounting-ear punch;
- and
- activating a joint punch;
- separating the segments from the blank and moving the segments to a base;
- and
- rotating the base.

- activating a profile punch, wherein the profile punch shapes at least one profile of the segment;
- activating a mounting-ear punch, wherein the mounting-ear punch shapes at least one mounting-ear of the segment;
- and
- activating an joint punch, wherein the joint punch shapes at least one joint of the segment;
- separating the segments from the blank and moving the segments to a base;
- and
- rotating the base.
