Abstract

FIELD: plastic metal working, cold stamping with use of pressure of elastic medium to manufacture extremely thin-walled members of piping systems. SUBSTANCE: filling agent is put into tubular skelp 9 with positioning of end parts 5 by points 8 of narrowing of rigid members 6 over sections of its transition to expanded part and central part 7 over section of maximum expansion. Then skelp is placed into impression of matrix 1 of stamping gear. In process of upsetting of skelp with filling agent there is created internal pressure of elastic medium which is distributed differentially over internal surface of skelp depending on degree of expansion. This makes it possible to manufacture extremely thin-walled articles of complex design with simultaneous decrease of rejects. EFFECT: reduced difference of internal pressure of elastic medium on sections of transition of skelp into expanded part. 1 dwg

Изобретение относится к обработке металлов давлением, в частности к холодной штамповке с использованием давления эластичной среды, и может быть использовано при получении особо тонкостенных элементов трубопроводных систем. Технический результат заключается в снижении перепада внутреннего давления эластичной среды на участках перехода заготовки в раздаваемую часть. В трубчатой заготовке устанавливают наполнитель, размещая концевые части местами сужения жестких элементов на участках перехода ее в раздаваемую часть, центральной частью, эластичного цилиндра на участке максимальной раздачи, и помещают заготовку в ручей матрицы устройства для штамповки. В процессе осевой осадки заготовки с наполнителем создают внутреннее давление эластичной среды, которое по внутренней поверхности заготовки распределяется дифференцировано в зависимости от степени раздачи. Это позволяет изготавливать особо тонкостенные изделия сложной конструкции при одновременном сокращении брака.The invention relates to the processing of metals by pressure, in particular to cold stamping using the pressure of an elastic medium, and can be used to obtain particularly thin-walled elements of pipeline systems. The technical result consists in reducing the differential pressure of the elastic medium in the areas of transition of the workpiece into the part being distributed. A filler is installed in the tubular billet, placing the end parts in places of narrowing of the rigid elements in the transition sections to the distributable part, with the central part of the elastic cylinder at the maximum distribution area, and placing the billet in the creek of the die of the stamping device. In the process of axial settlement of the preform with a filler, an internal pressure of an elastic medium is created, which is distributed differentially over the inner surface of the preform depending on the degree of distribution. This allows us to produce particularly thin-walled products of complex design while reducing rejects.
