Способ относится к обработке металлов давлением, а именно к изготовлению глубоких тонкостенных цилиндрических изделий из многогранных листовых заготовок с помощью многопереходной технологии комбинированной вытяжки. В целях экономии штампуемого металла при получении многогранной заготовки и получении изделия с ровным без "коронок" краем многогранную заготовку получают вырубкой или отрезкой из листового проката и подвергают многопереходной вытяжке по комбинированной схеме. На первом переходе вытяжку осуществляют цилиндрическим пуансоном, на боковой поверхности которого выполнены лыски по числу граней заготовки глубиной, равной 0,1 - 0,25 зазора между матрицей и цилиндрической поверхностью пуансона, а на последующих - такими же по форме пуансонами. При вытяжке заготовку или полуфабрикат ориентируют вершинами "коронок" по лыскам. После вытяжки полуфабрикат получается с переменной по периметру толщиной стенки. На последней операции комбинированную вытяжку осуществляют с равномерным по периметру зазором.The method relates to the processing of metals by pressure, in particular to the manufacture of deep thin-walled cylindrical products from multi-faceted sheet blanks using multi-transition technology of combined drawing. In order to save stamped metal, when receiving a multi-faceted billet and getting a product with an even without a crown edge, a multi-faceted billet is produced by cutting or cutting out of sheet metal and is subjected to a multi-transition drawing according to a combined pattern. At the first transition, the hood is carried out with a cylindrical punch, on the side surface of which the flats are made according to the number of faces of the workpiece with a depth of 0.1 - 0.25 gap between the die and the cylindrical surface of the punch, and at subsequent ones - with the same shape of punches. When drawing a billet or semi-finished product orient the "crowns" tops on the flats. After drawing, the semi-finished product is obtained with a wall thickness that varies along the perimeter. In the last operation, the combined hood is carried out with a uniform gap around the perimeter.
