RING-SHAPED OR PLATE-LIKE ELEMENT AND METHOD FOR PRODUCING SAME

摘要

A ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, for example for devices which are subjected to high pressures, such as igniters for airbags or belt tensioning devices, includes a feedthrough opening, whereby the feedthrough opening is located substantially in the center of the ring-shaped or plate-like element and whereby the ring-shaped or plate-like element has a thickness. The ring-shaped or plate-like element has a relief region in the area of the feedthrough opening. Further, the ring-shaped or plate-like element in the relief region has at least one thickness which is reduced by the height of the relief region and which is selected so that the feedthrough opening can be punched out of the ring-shaped or plate like element having the reducing thickness.

主权项

1. A method of producing a base body for a metal-sealing material-feedthrough, the method comprising the steps of:
providing a blank from a wire-shaped material for processing; processing said blank to reshape said blank into one of a ring-shaped element and a plate-like shaped element having a front side and a rear side; pressing one of said ring-shaped element and plate-like element against a punch, whereby the material of one of said ring-shaped element and plate-like element surrounding said punch in order to incorporate at least one of a relief region at said rear side of the element which is characterized by a reduced thickness, punching one of said ring-shaped element and said plate-like shaped element formed from said processing step to incorporate a feedthrough opening extending from a front side of the element to a rear side of the element and being located within the relief region.
