Abstract

Изобретение относитс  к станкостроению и может быть использовано дл  отрезки деталей трубчатой формы при совмещенной обработке их резанием и пластическим деформированием. Целью изобретени   вл етс  повышение стойкости отрезного инструмента путем снижени  усилий резани  при отрезке. В полость заготовки ввод т раскатник, обеспечивают необходимую величину нат га раскатных роликов и сообщают подачу резцу 1 и жестко св занному с ним деформирующему ролику 3. Проход резца осуществл ют до половины толщины стенки заготовки. При этом резец 1 работает в зоне окружных раст гивающих напр жений, обеспечиваемых раскатными роликами, и осевых раст гивающих напр жений, создаваемых роликом 3. Затем резец 1 выводитс  из зоны резани , а резец 2 осуществл ет прорезку оставшейс  толщины стенки, работа , как и резец 1, в зоне раст гивающих напр жений. 4 ил.The invention relates to a machine tool industry and can be used for cutting pieces of tubular shape with a combined treatment of their cutting and plastic deformation. The aim of the invention is to increase the durability of the cutting tool by reducing the cutting forces during the cutting. A raskatnik is introduced into the preform cavity, the required amount of tension of the rollers is provided, and the cutter 1 and the deforming roller 3 rigidly connected with it are fed. The cutter passes to the half of the wall thickness of the preform. The cutter 1 operates in the zone of circumferential tensile stresses provided by the rolling rollers and the axial tensile stresses generated by the roller 3. Then the cutter 1 is taken out of the cutting zone, and the cutter 2 cuts through the remaining wall thickness, working as cutter 1, in the tensile stress zone. 4 il.

Формула изобретенияClaim Способ отрезки деталей трубчатой формы при растяжении зоны обработки в направлении, перпендикулярном подаче режущих инструментов, направленной к оси вращения детали, отличающийся тем, что, с целью повышения стойкости резцов, зону обработки дополнительно растягивают в направлении, параллельном направлению подачи режущих инструментов, для чего в полости детали в одной плоскости с режущими инструмен тами размещают не менее двух равнорасположенных роликов, причем первоначально отрезку до половины толщины стенки детали осуществляют резцом, расположенным на5 против ролика, а последующую обработку ведут другим резцом, равноудаленным от соседних роликов.The method of cutting tubular shaped parts by stretching the processing zone in a direction perpendicular to the supply of cutting tools directed to the axis of rotation of the part, characterized in that, in order to increase the resistance of the cutters, the processing zone is additionally stretched in a direction parallel to the feed direction of the cutting tools, for which the cavity of the part in the same plane with the cutting tools is placed at least two equally spaced rollers, and initially cut to half the wall thickness of the part is carried out by a cutter m na5 disposed against the roller, and the subsequent processing of another lead cutter, equidistant from adjacent rollers.
