Способ листовой штамповки-вытяжки деталей типа "чашка" из тугоплавких металлов с нерекристаллизованной структурой преимущественно молибдена и его сплавов, включающий изготовление штампа с зазором между пуансоном и матрицей, рассчитанным по номинальной толщине листа, вырубку заготовок-дисков и их смазку, подогрев заготовок и штампа, отличающийся тем, что заготовки - листы партии, подлежащие штамповке, сортируют на две группы с плюсовым и минусовым допуском, изготавливают два штампа с разными зазорами с учетом допуска на толщину листа и наплыва-утолщения цилиндрической части штамповки, листы с плюсовым допуском штампуют на штампе с большим зазором, листы с минусовым допуском - на штампе с меньшим зазором.A method of sheet stamping-drawing of cup-type parts from refractory metals with an unrecrystallized structure of predominantly molybdenum and its alloys, including the manufacture of a stamp with a gap between the punch and the die calculated by the nominal thickness of the sheet, cutting blanks-discs and their lubrication, heating the blanks and stamp characterized in that the blanks — batch sheets to be stamped are sorted into two groups with plus and minus tolerance, two stamps with different clearances are made taking into account the tolerance on the sheet thickness and n Swim-thickened cylindrical part punching sheets are punched to the positive tolerance to the die with a large gap, sheets with a minus tolerance - on a smaller die gap.
