Description
СПОСОБ ИЗГОТОВЛЕНИЯ ИЗДЕЛИЙ ТИПА УГОЛКОВMETHOD OF PRODUCING PRODUCTS OF TYPE OF CORNERS

ИзобретенИе относитс к области обработки металлов давлением, в частности к технологии гибки.The invention relates to the field of metal forming, in particular, to the technology of bending.
Известен способ изготовлени изделий типа уголков путем гибки листовых заготовок в штампе.A known method of manufacturing angular products is by bending sheet blanks in a die.
По известному способу не может быть получен радиус изгиба, меньший допустимого, величина которого обусловлена предельно допустимыми нап.р жени ми на раст нутой стороне заготовки при гибке.By a known method, a bend radius smaller than the allowable one cannot be obtained, the value of which is determined by the maximum allowable stress on the stretched side of the workpiece during bending.
С целью уменьшени допустимого радиуса изгиба по предлагаемому способу на заготовку предварительно нанос т поперечные риски со стороны, подвергаемой раст жению в процессе гибки, глубиной, увеличиваюш,ейс по мере удалени от линии гиба.In order to reduce the permissible bending radius of the proposed method, lateral risks are preliminarily applied to the workpiece from the side subjected to stretching during the bending process, with a depth that increases as it moves away from the bend line.
Глубина рисок зависит от радиуса изгиба, свойств материала, формы и способы их нанесени . Риски нанос т любым известным способом (штамповкой, резанием и т. д.). При гибке заготовки с рисками в местных предварительного утонени возникают благопри тные услови дл развити дефомаций, что приводит к разгрузке центрального, наиболее напр женного при гибке сечени , и в конечном итоге к возможности уменьшени допустимого радиуса изгиба.The depth of scratches depends on the bend radius, material properties, shape and methods of their application. Risks are applied by any known method (by stamping, cutting, etc.). When bending the workpiece with risks in local pre-thinning, favorable conditions arise for the development of defamations, which leads to unloading of the central, most stressed during the bending of the section, and ultimately to the possibility of reducing the allowable bending radius.
