Abstract
Изобретение относитс к области металлообработки и может быть использовано при прот гивании глубоких отверстий. Цель изобретени - повышение производительности прот гивани за счет уменьшени длины прот жки. Прот гивание осуш,ест- вл етс прерывисто комбинированной прот жкой 1, содержаш,ей деформируюш,ий 2 и дополнительный 3 элементы, а также ре- жуш.ую секцию 4, состо щую из зуба 5 и стружечной канавки 6. Дополнительный элемент 3 располагают между деформи- РУЮШ.ИМ элементом и режушим зубом в максимуме волны внеконтактной деформации , причем его диаметр и положение в прот жке определ ют из следуюших соотношений: dg dg rfa+U, где ds - диаметр деформирующего элемента; U - величина упругого восстановлени обработанного отверсти ; da - диаметр дополнительного элемента,,447 а° д/t- D, где а - нат г на дефор.мирующий элемент; t - толщина стенки детали; D - диаметр прот гиваемого отверсти . В момент остановки процесса обрабатываема поверхность входит в контакт с дополнительным элементом с образованием остаточной кольцевой канавки, обеспечивающей деление стружки по длине, что обеспечивает возможность работы с большим подъемом на зуб. 2 ил. (О слThis invention relates to the field of metalworking and can be used to draw deep holes. The purpose of the invention is to increase the productivity of the drawing by reducing the length of the draw. Pulling dry is intermittently combined by pulling 1, containing, deforming, 2 and an additional 3 elements, as well as a holding section 4, consisting of a tooth 5 and a chip groove 6. An additional element 3 between the deformation element and the tooth cutting at the maximum of a non-contact deformation wave, and its diameter and position in the broach are determined from the following relations: dg dg rfa + U, where ds is the diameter of the deforming element U is the elastic recovery value of the machined hole; da is the diameter of the additional element, 447 a & d / t - D, where a - nat g on the deforming element; t is the wall thickness of the part; D is the diameter of the hole being drawn. At the moment of stopping the process, the surface to be processed comes into contact with an additional element with the formation of a residual annular groove, which ensures the division of chips along the length, which makes it possible to work with a large lift to the tooth. 2 Il.
