Abstract

FIELD: powder metallurgy. SUBSTANCE: method involves charging powder into die; providing cold pressing by applying discrete impacts; withdrawing and effectuating sintering; forming lock in section, with powder material density gradient being taken into account during calculation of section; providing thermal fixation and final mechanical working. EFFECT: increased efficiency, improved quality by reduced wearing of cylinder-piston ring pair.

Изобретение относится к порошковой металлургии и может быть использовано для изготовления порошковых поршневых колец. Изобретение позволяет уменьшить износ пары "цилиндр - поршневое кольцо". Способ включает следующие операции: засыпку порошка в матрицу, холодное прессование дискретными усилиями, извлечение заготовки, ее спекание, формирование замка в сечении, определяемом с учетом градиента плотности порошкового материала, термофиксирование и окончательную механическую обработку.The invention relates to powder metallurgy and can be used for the manufacture of powder piston rings. EFFECT: invention makes it possible to reduce wear of a cylinder-piston ring pair. The method includes the following operations: filling the powder into the matrix, cold pressing with discrete forces, removing the billet, sintering it, forming a lock in the cross section, determined taking into account the density gradient of the powder material, heat fixing and final machining.
