A race for a mechanical clutch assembly may be formed from multiple race layers that assembled from pluralities of stamped arcuate segments. First and second race layers may have the same shape when their arcuate segments are assembled are assembled. The arcuate segments of the first race layer may be identical to each other, and the arcuate segments of the second race layer may be identical to each other, but the first layer arcuate segments are not identical to the second layer arcuate segments. Interlocking joints between the first layer arcuate segments are not aligned with interlocking joints between the second layer arcuate segments when the race layers are joined together and aligned for use in the mechanical clutch assembly.

A system and process for fabricating motor laminations from sheet material. Various embodiments of the disclosure combine a separation process with one or both of a cutting and a scoring process that outlines the laminations prior to the separation process. In some embodiments, the separation process is a punching process and is integrated with the stacking of the motor laminations to form the stator core. In addition, a system and process where the cut and/or scored portion of the sheet material is subjected to flattening process prior to the separation process is disclosed. Performing the flattening process prior to the separation process has the effect of streamlining the process, in that the sheet material can be easily handled and conveyed from the scoring process, through the flattening process, and to the separation and stacking process, without need for separate handling of the laminations.

A chain link for a conveyor chain includes a planar elongate sheet metal conveying body having four outer corners and sides that extend between adjacent outer corners, the sides include long sides and short sides that extend between the long sides, the sides further include side face portions that extend substantially transversely to a conveying plane of the conveying body, and at each of the outer corners, the conveying body may include a corner face portion that extends transversely to the conveying plane and that connects angularly to a side face portion of a short side.

A method of manufacturing a nut integrated with a bracket forms the nut formed integrally with the bracket or a slab base nut by using a plate material supplied between a punch and a die. The slab base nut includes a base plate and a boss extending from the base plate and including female-threads. The base plate and the boss are integrated into a single piece without welding trace.

A laminated member as a laminate of a plurality of alloy ribbons is used. The laminated member has a side surface with a fracture surface. A laminated body as a laminate of the laminated member is used. A motor that includes a core using the laminated body is used. A method for manufacturing a laminated member is used that includes: fixing a plurality of amorphous ribbons to one another in a part of layers of the amorphous ribbons after laminating the amorphous ribbons; and punching a laminated member by cutting the laminate of the amorphous ribbons at a location that excludes the portion fixing the amorphous ribbons in the laminate.

A stamping strip manufacturing system comprises a stamping machine forming terminals in a strip by stamping, a supply reel around which the strip to be stamped is wound for supplying the strip to be stamped to the stamping machine, and a recovery reel around which the stamped strip is wound for recovering the stamped strip. The system further includes an autonomous mobile robot on which a cutting tool and a welding tool are mounted. The autonomous mobile robot is adapted to cut off an unqualified strip segment of the stamped strip having an unqualified terminal by operating the cutting tool, and to weld two cut ends of the cut strip to each other by operating the welding tool.
