Description
(54) ИНСТРУМЕНТ ДЛЯ ПРЕССОВАНИЯ ТРУБ(54) TOOL FOR PIPE PRESSING
1one
Изобретение относитс к обработке металлов давлением, а именно к конструкции прессового инструмента дл прессовани труб.The invention relates to the processing of metals by pressure, in particular to the design of a pressing tool for pressing pipes.
Известен инструмент дл прессовани труб, содержащий контейнер с размещенной в нем матрицей, т гой и нресс1Ьайбой.A tool for pressing pipes is known, which contains a container with a die, traction and press-fit.
Однако при работе в процессе прошивки, при движении иглы вперед, в определенный момент происходит отрыв части мета.кла в зоне между передним торцом иглы и матрицы . Этот объем выталкиваетс иглой через очко матрицы, образу так называемую «переднюю пробку, котора г л етс отходом, а ее величина может достигать и более от первоначального веса слитка.However, when working during the flashing process, when the needle moves forward, at a certain moment, a part of the metaclock is torn off in the area between the front end of the needle and the die. This volume is pushed out by the needle through the point of the matrix, forming the so-called "front stopper", which becomes waste, and its value can reach even more than the initial weight of the ingot.
Наиболее б.лизким техническим реи1еиием к изобретению вл етс прессовый инструмент , включающий контейнер с размещенной в нем матррщей с обжимным участком, заострешюй иглой и прессшайбой.The most technical solution to the invention is a pressing tool, including a container with a mat with a crimping section, a pointed needle and a press washer.
Недостаток указанного уст|1ойства заключаетс в с.южиости ирисиособ.леин дл перемещени мат)11цы, в необходимости дополнительн1 1х операций, вынолненных оператором пресса, а также в удлинении циклаThe disadvantage of this device is in the manpower irisiosle.lein for moving the mat, the need for additional 1x operations, performed by the press operator, as well as in lengthening the cycle
нрессовани и сниженни производительности агрегата.compressing and reducing the performance of the unit.
Кроме того, работа в таком режиме ненадежна , а порой невозможна из-за недостаточности сил трени металла по стенкам контейнера, удерживающих с,щток на рассто нии от матрицы.In addition, work in this mode is unreliable, and sometimes impossible due to the inadequacy of the friction forces of the metal along the walls of the container, which hold c and the brushes away from the matrix.
Целью изобретени вл етс обеснечение надежности ироцесса прошивки слитка без образовани нередней пробки.The aim of the invention is to deplete the reliability of the process of the ingot firmware without the formation of an irregular plug.
Это достигаетс тем, что в матрице выполнена камера дл свободного раскрыти торца пропщваемого слитка, котора размещена перед обжимпым участком матрицы и имеет диаметр заходного отверсти равный 1,5-4 диаметра иглы, высоту 0,3 - 1,1 диаметра , а 6oKOBi)ie стороны образующие камер , расно,южены к осн матрицы под yr;io О-45°.This is achieved by the fact that in the matrix there is a chamber for free opening of the end of the bored ingot, which is located in front of the crimping section of the matrix and has a diameter of the inlet opening 1.5-4 needle diameters, height 0.3 - 1.1 diameters and 6oKOBi the sides forming the chambers, rasno, are south to the basis of the matrix under yr; io O-45 °.
На фиг. 1 иоказан инструмент в момент, предшествующий окончанию ироцесса ироНИ1ВКИ слитка, продольный разрез; на фи1 2 - то же, после оконча1и1 .FIG. 1 and the tool is shown at the time preceding the end of the ingot iroNI1VKI process, longitudinal section; on fi1 2 - the same, after the ending1.
