Ликвидация разрушения твердосплавных волок при обработке полос из сплавов электросопротивления

Abstract

Carbide dies with the traditional channel parameters showed an unsatisfactory resistance to fracture during drawing nichrome and ferrochrome bands . In order to increase their resistance by forces favorable direction normal to the surface of the canal zone, reducing the probability of failure, a die complied with the length of the output area equal to 0.24-0,32 the full length of the channel . With the improved channel smoothed voltage in weakened areas in the zone of action of maximum stress they confront a larger section of the insert and holder, reduced stress intensity, the destruction of insertions eliminated.
