Method for production of a contact piece for a switchgear assembly, as well as a contact piece itself

摘要

The disclosure relates to a method for production of a component, such as a contact piece, for a switchgear assembly. To introduce a slot and apply a contact outer contour directly during the powder-metallurgical production process of the contact material, contouring in the form of a slot or slots is introduced into the powder-metal material, which is located in a mold, essentially in a direction parallel to a normal to a surface of the component, to form the component with a slot.

主权项

1. A method for powder-metallurgical production of a component of a switching device, comprising:
placing powder-metal material into a mold; arranging a film between a lower die of a pressing tool and the mold on one side and the powder-metal material on another side; providing a plurality of inserts through openings in the lower die; and contouring slots into a surface of the powder-metal material by applying the plurality of inserts to the film and to the powder-metal material where the slots are to be formed, using a pressing process in a direction normal to the film and to the surface of the powder-metal material to form the slots in the component.
