Abstract
Способ изготовления тонкостенных крупногабаритных оболочек оживальной формы из заготовки конусной формы из малопластичных труднодеформируемых сталей путем однопереходной штамповкой в штампе, выполненном с зазором между матрицей и пуансоном, с предварительным нагревом заготовки, отличающийся тем, что перед штамповкой со стороны большего диаметра заготовки формируют фланец для зажима ее в матрице, а нагрев заготовки производят до температуры, определяемой по пределу прочности, найденному из соотношения: ! ! где σBt - предел прочности нагретой заготовки; ! σB - предел прочности обрабатываемого материала при t=20°; ! mB - коэффициент вытяжки при t=20° в точке максимального прогиба; ! mBt - коэффициент вытяжки в точке максимального прогиба при нагреве; ! К - коэффициент пропорциональности, выведенный опытным путем, зависящий от механических свойств обрабатываемого материала.A method of manufacturing thin-walled large-sized shells of a lively shape from a cone-shaped blank from low-plastic hardly deformed steels by single-pass stamping in a stamp made with a gap between the die and the punch, with pre-heating the blank, characterized in that a flange is formed before stamping from the side of the larger diameter of the blank to clamp it in the matrix, and the workpiece is heated to a temperature determined by the tensile strength found from the relation:! ! where σBt is the tensile strength of the heated billet; ! σB is the tensile strength of the processed material at t = 20 °; ! mB is the drawing coefficient at t = 20 ° at the point of maximum deflection; ! mBt is the drawing coefficient at the point of maximum deflection during heating; ! K is the coefficient of proportionality, derived empirically, depending on the mechanical properties of the processed material.
