Анализ условий формоизменения относительно толстолистовых заготовок с целью расширения возможностей процесса деформирования

Abstract

In the article possibilities changes of form of sheet purveyances are analysed by the operation of extraction without the clamp of flanec. It is shown that the coefficient of extraction depends on the geometrical parameters of purveyance and got good and geometry of instrument. It is reasonable in theory, that on an increment of meridional tensions size from the bend of purveyance on the edge of matrix large influence renders the radius of rounding of edge and corner between the generatrix of cone and axis of symmetry.
