Abstract
Изобретение относитс к обработке металлов давлением, в частности к листовой штамповке, и может быть использовано при изготовлении тонкостенных полых деталей путем глубокой выт жки. Цель изобретени - расширение технологических возможностей за счет обеспечени выт жки детали из тонколистовой заготовки с толщиной менее 1,2 мм и относительной толщиной менее 0,005. Штамп содержит пуансон 1, матрицу 2, основной 3 и дополнительный наружный прижимы в виде усеченных конусов, эластичную среду 5, эластичное кольцо 6, установленное в рабочем отверстии матрицы 2 на ее основной конической поверхности 7. Отверстие эластичного кольца 6 сужаетс в сторону дополнительной конической поверхности 10 матрицы 2, а наименьший диаметр не меньше величины меньшего диаметра конусной поверхности основного прижима 3. При выт жке эластичное кольцо создает подпор свободной от прижимов боковой поверхности полуфабриката, чем исключает складкообразование. 2 ил.The invention relates to the processing of metals by pressure, in particular to stamping, and can be used in the manufacture of thin-walled hollow parts by deep-drawing. The purpose of the invention is the expansion of technological capabilities due to the provision of drawing a part from a thin sheet blank with a thickness of less than 1.2 mm and a relative thickness of less than 0.005. The stamp contains a punch 1, a matrix 2, a main 3 and an additional outer clamps in the form of truncated cones, elastic medium 5, an elastic ring 6 installed in the working hole of the matrix 2 on its main conical surface 7. The opening of the elastic ring 6 tapers towards an additional conical surface 10 of the matrix 2, and the smallest diameter is not less than the smaller diameter of the conical surface of the main clamp 3. When stretched, the elastic ring provides support for the side surface of the semifinished product that is free of the presses than exclude wrinkling. 2 Il.
