КОНТАКТНАЯ ПЛАСТИНА И СПОСОБ ЕЕ ИЗГОТОВЛЕНИЯ

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to powder metallurgy. Particularly it relates to structure and method of production of sintered contact plate. It can be used for outfitting of current collector for railway vehicle. Contact plate is implemented in the form of strip made of posder antifriction material on the basis of copper and contains plastic layer made of powder from copper or iron. Into plastic layer there are pressed in fastening bolts. Blank for contact plate and by holes for bolts there are formed in a press during the press process. Fastening bolts, preinstalled in press mold, are pressed into heated blank during the compression process. ^ EFFECT: received plate allows high mechanical properties and allows increased operating resource. ^ 2 cl, 1 dwg, 2 ex
