Description
Изобретение относитс к области обработки металлов давлением и может быть использовано при производстве гаек.The invention relates to the field of metal forming and can be used in the manufacture of nuts.
Известен способ получени внутренней резьбы методом пластической деформации , а именно, накатыванием роликовыми головками 1.A known method for producing internal threads by the method of plastic deformation, namely, by rolling roller heads 1.
Указанный способ имеет следующие недостатки s длительный процесс получени резьбы не дает возможности подн ть производительность труда на этой операции s значительных пределах;дл . изготовлени указанного инструмента расходуютс высококачественные инструментальные стали; сравнительно сложна наладка на каждый типоразмер нарезаемой резьбы; накатка и выдавливание резьбы в качественных и высоколегированных стал х затруднительна ввиду высоких механических свойств этих сталей.This method has the following disadvantages; the long process of obtaining threads makes it impossible to raise the productivity of labor in this operation over considerable limits; the manufacture of this tool consumes high-quality tool steels; relatively difficult to set up for each size of cut thread; knurling and extruding threads in high-quality and high-alloyed steels are difficult due to the high mechanical properties of these steels.
Наиболее близким из известных способов к изобретению вл етс выдавливание внутренней резьбы с помощью метчика 2.The closest of the known methods to the invention is the extrusion of internal threads using a tap 2.
Этот способ обладает вышеприведенными недостаткамиThis method has the above disadvantages.
Целью изобретени вл етс повышение производительности труда при изготовлении деталей с внутренней резьбой .The aim of the invention is to increase labor productivity in the manufacture of parts with internal threads.
Поставленна цель достигаетс тем, что заготовку с внутренним отверстием, большим наружного диаметра получаемой резьбы, подвергают объемному обжатию на инструменте, который затем извлекают из заготовки вращением.The goal is achieved by the fact that the workpiece with an internal hole, large outer diameter of the obtained thread, is subjected to volumetric compression on the tool, which is then removed from the workpiece by rotation.
На фиг. 1 показана установка дл получени внутренней резьбы одновременно на всей длине нарезки методом объемной пластической деформации в продольном разреза; на фиг« 2 - разрез А-А на фиго 1; на фиг. 3 - раз5 рез Б-Б на фиг с 2.FIG. Figure 1 shows an installation for producing an internal thread simultaneously over the entire length of cutting by the method of volumetric plastic deformation in a longitudinal section; Fig "2 - section aa in Figo 1; in fig. 3 - time5 cut BB in FIG. 2.
Установка содержит подвижный пуансон 1, в который устанавливаетс заготовка 2 гайки дл образовани в ней внутрекней резьбы, стакан 3, обеспе0 чивающий поперечное обжатие, боковые стойки 4 и 5, формирующий инструмент 6 дл образовани внутренней резьбы, :имеющий два одинаковых резьбовых участка , калибрующую втулку 7, матрицу 8, The installation contains a movable punch 1, in which the blank 2 is installed to form an internal thread in it, a cup 3 providing lateral reduction, side racks 4 and 5 forming a tool 6 for forming an internal thread: having two identical threaded sections calibrating the sleeve 7, matrix 8,
5 а также стойки 9 и 10, органичивающив .толщину гайки,5 as well as racks 9 and 10, the thickness of the nut;
Изготовление гаек осуществл етс следующим образом.The manufacture of nuts is carried out as follows.
Отштампованна заготовка 2 гайки Stamped billet 2 nuts
0 с наружными размерами, обеспечивающи0 with external dimensions providing
