Device for electric longitudinal-seam mash resistance welding

A numerically controlled groove-stamping machine which includes an indexing unit rotatable stepwise by means of a positioning drive about a rotational axis as a function of a stroke of a punch of the groove-stamping machine. The indexing unit is adapted to be driven, in a stepwise fashion, in two intersecting directions running at right angles to the rotational axis. A numerically controlled automatic multiple tool set is provided with the set being equipped with, for example, a stator groove and cut-off tool, a rotor groove tool, and vent hole tools. The tools of the multiple tool set, in accordance with the work steps to be executed, are adapted to be brought into engagement in an individually controllable manner.

Numerically controlled groove-stamping machine

In loading a press, it is desirable to provide a loading device which can be driven independently of the main driving means of the press and which causes a minimum of surface damage to the blanks being loaded into the press. To achieve this, gripper elements are provided which are coupled to adjustable drive systems controlled by a numerical control unit. The gripper elements are capable of motion in at least two planes perpendicular to each other to remove devices from the stack and carry them along a preselected path into a tool chamber of the press.
