New developments in technology formation of products electrotechnical appointment on the basis of carbon

摘要

In this paper provides an analysis of existing processes and press-dies for the manufacture of products electrotechnical appointment mass use (brushes, contact inserts of trolleybuses and trams) on the basis of carbon. Proposed and tested simplified versions forming process, in which raw materials are waste products of graphite electrodes, and no firing and graphitizing operations and finish machining. To carry out the forming process developed design of press-dies for the two and three-way forming a multi-forming for use on the universal press equipment. Original methods of forming and design the press-dies are protected by patents and allow to obtain products of high density and quality.
