An assembly for assembling a winding group of a bar winding for an electric machine is provided. The winding group includes a plurality of bar conductors, each bar conductor having a first leg, a second leg and a bridge portion connecting the first leg to the second leg, and being shaped so that the first and second legs are mutually spread by a predetermined distance. The assembly includes an annular fixture delimiting a plurality of slots, each slot receiving at least one portion of either the first leg or the second leg, a guiding device defining an annular containment housing, receiving at least partially the first and second legs of the plurality of legs of the plurality of bar conductors that are housed in the plurality of slots, forming at least one radial containment wall for the first and second legs.

A device for mounting a plug in a hollow shaft is disclosed. The device includes a holding device for holding the plug to be mounted and a joining device for sliding the hollow shaft onto the plug held in the holding device. The holding device is radially adjustable relative to an axis of the hollow shaft to compensate for an axial offset between the axis of the hollow shaft and an axis of the plug. The joining device can be inclined to compensate for an inclined position of the axis of the hollow shaft and the axis of the plug.

A split-type laminated iron core is composed by laminating a plurality of metal plate materials having an annular shape. The metal plate material includes a first split piece and a second split piece arranged in a circumferential direction and divided by a predetermined cutting line. A shear surface formed on a first end surface of the first split piece and a shear surface formed on a second end surface of the second split piece abut on each other, and the first split piece and the second split piece are temporarily connected via the cutting line defined by a boundary between the first end surface and the second end surface so that the first end surface and the second end surface do not completely overlap.

Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.

Techniques for implementing and/or deploying a swage machine, which includes a die plate that enables a die to be used to conformally deform a pipe fitting around pipe segment tubing to be loaded in the swage machine, a grab plate having grab plate sections that are pivotably connected, and grab adapter sections. Each grab adapter sections includes a base sub-section connected to a corresponding grab plate section, in which an inner surface of the base sub-section includes an alignment notch, and a modular sub-section to be secured to the base sub-section, in which an outer surface of the modular sub-section includes an alignment tab to be disposed within the alignment notch in the base sub-section and an inner surface of the modular sub-section includes a grab tab section that matingly interlocks with a fitting grab notch on the pipe fitting to facilitate securing the swage machine to the pipe fitting.

Aspects of the disclosure relate to hub puller kit apparatus and methods, and associated components thereof, for pulling hubs off of power ends. In one example, the hub puller kit apparatus and methods are used to pull a hub off of a power end of a frac pump.

An extraction tool for extracting a shim located in a turbomachine and provided with a through-hole, includes an extractor pin configured to be inserted into the through-hole of the shim; a first gripping member with a first distal end intended to be positioned opposite the through-hole on a first side of the shim and arranged to retain a first end of the extractor pin; and a second gripping member including a second distal end intended to be positioned opposite the through-hole on a second, opposite side of the shim, and arranged to retain a second, opposite end of the extractor pin, after the extractor pin has been inserted into the through-hole of the shim.

A system and method for servicing a welding torch is provided. The system includes a gripping module for holding and releasing a component of the welding torch, the gripping module is movable along an axis of the gripping module and rotatable about the axis; and a control system for providing a degree of freedom in a movement of the gripping module to control or reduce a force exerted between mating components of the welding torch.

A bell cup multi-tool and method is provided for ergonomic straight-line force applications. The multi-tool includes a manipulator for providing the straight-line pressure to a distributor in a bell cup for installation or removal. The multi-tool also includes a base for securing the bell cup in a desired orientation.
