Claims (1)

Способ изготовления промежуточной заготовки для коллектора электродвигателя, включающий выдавливание из прутковой заготовки стакана с формированием опорных выступов ламелей, выполненных на его внутренней боковой поверхности, пуансоном, на рабочем конце которого выполнены продольные пазы, имеющие в поперечном сечении форму поперечного сечения формируемых опорных выступов ламелей, удаление дна стакана и обточку торцов, отличающийся тем, что откалиброванную прутковую заготовку сначала помещают в цилиндрическую закрытую с одного конца матрицу и указанный пуансон при продольном выдавливании стакана внедряют в заготовку на неполную длину продольных пазов, а затем, не снимая стакана с пуансона, тем же пуансоном протягивают через сквозную матрицу вытяжки с калибрующим круглым отверстием до образования полости с глубиной, равной длине ламелей коллектора и их лепестков.A method of manufacturing an intermediate billet for an electric motor collector, including extruding a cup from a rod billet with the formation of supporting lamella protrusions made on its inner side surface, by a punch, at the working end of which longitudinal grooves are made having a cross-sectional cross-sectional shape of the formed lamella supporting protrusions, removal the bottom of the glass and the turning of the ends, characterized in that the calibrated bar stock is first placed in a cylindrical closed at one end and the matrix and the specified punch during longitudinal extrusion of the cup are introduced into the workpiece to the incomplete length of the longitudinal grooves, and then, without removing the cup from the punch, the same punch is pulled through the through drawing matrix with a calibrating round hole to form a cavity with a depth equal to the length of the collector lamellas and their petals.
