Description
Изобретение относитс к области металлообработки и может быть исполь зовано в инструментальной промьи ленности .The invention relates to the field of metalworking and can be used in the instrumental industry.
Известна конструкци плашки со cмeнны Aи гребенками, установленными в корпусе на резьбовых опорах и закрепленными посредством подвижных элементов 1,The known construction of the die with the change A and the dies mounted in the housing on the threaded supports and fixed by means of the movable elements 1,
Недостатком известной конструк- . ции вл етс ненадежное крепление гребенок в корпусе, так как крепление осуществл етс только за рчет сил трени .The disadvantage of the known constructions. This is the unreliable fastening of the dies in the housing, since the fastening is carried out only due to friction forces.
Целью изобретени вл етс повышение надежности креплени гребенок.The aim of the invention is to increase the reliability of fastening of the dies.
Поставленна цель достигаетс тем, что подвижные элементы выполнены в виде сегментов с двусторонними резьбовыми секторами,причем каждый сегмент предназначен дл -взаимодействи одновременно с двум гребенками .The goal is achieved by the fact that the movable elements are made in the form of segments with double-sided threaded sectors, each segment being designed to interact with two dies simultaneously.
На фиг. 1 схематически изображена предлагаема плашка со сменными гребенками,- на фиг; 2 - сечение А-А на фиг. 1; на фиг, 3 - подвизкный крепежный элемент.FIG. 1 schematically shows the proposed die with interchangeable dies, - FIG; 2 is a section A-A in FIG. one; in FIG. 3 — an attachment fastener.
Плашка состоит из корпуса 1, цилиндрических резьбонарезных гребенок 2, фиксирующих сегментов 3, эксцентричных пальцев 4, шпонок 5, винтов б и 7.The plate consists of a housing 1, cylindrical thread-cutting dies 2, fixing segments 3, eccentric fingers 4, dowels 5, screws b and 7.
В корпусе 1 выполнено центральное отверстие 8 дл прохода нарезаемого болта и три резьбовые отверсти 9, в которые установлены эксцентричные пальцы 4. Гребенки 2 одеваютс на эксцентричные пальцы 4.In the housing 1 there is a central opening 8 for the passage of the bolt being cut and three threaded holes 9 in which eccentric fingers 4 are installed. Combs 2 put on eccentric fingers 4.

Смещение резьбы у гребенок 2 на часть шага резьбы по отношению к смежной гребенке .выполнено занижением плоскости 10 корпуса 1.The displacement of the thread in the comb 2 on the part of the thread pitch relative to the adjacent comb. Performed by understating the plane 10 of the housing 1.
Регулировка отклонени среднего 5 диаметра наружной резьбы осуществл етс по резьбовому шаблону путем смещени гребенок 2 в радиальном направлении с помощью эксцентричных пальцев 4.The deviation of the average 5 diameter of the external thread is adjusted according to the threaded pattern by displacing the dies 2 in the radial direction using eccentric pins 4.
2020
Положение передней режущей грани фиксируетс с помощью шпонки 5, вход щей в выборку 11 симметрично относительно осей Х-Х и Y -Y гребенки 2.The position of the front cutting face is fixed by means of a key 5, which is included in sample 11, symmetrically with respect to the axes X-X and Y-Y of the comb 2.
2525
Гребенки 2 от смещени при резании удерживаютс сегментами 3 с двусторонними секторами 12, контактирующими с резьбой двух гребенок 2. После закреплени сегментов 3 винтами 7 образуетс неподвижное реэьThe combs 2 are prevented from cutting during the cutting by the segments 3 with double-sided sectors 12 in contact with the thread of the two combs 2. After the segments 3 are fixed with screws 7, a stationary beam is formed
