Description

Предлагаемое изобретение касаетс  устройства Дл  двуотупенчатого волочени  труб и имеет целью как ускорение процесса волочени , так и повышение качества продукции путем одйовременного волочени  и прокатки.чThe present invention relates to a device for two-step drawing of pipes and is aimed at both accelerating the drawing process and improving the quality of products by simultaneously drawing and rolling.

Устройство дл  двуступенчатого волочени  труб, изображенное на чертеже, состоит из станины 1 с подшипниками 2, 3 и 4, имеющими разъемные крышки и служащими дл  поддержани  матриц 5 и 6 с разными внутренними диаметрами, вращающихс  помощью .шкивов 7, 8, закрепленных на них шпонками 9, 9. Сердечних 11, один конец которого задерживаетс  вилкой 14 станины 15, несет на другом своем конце две оправки 12, 13 с разными диаметрами. С целью предупреждени  вращени  обрабатываемой трубы при вращательном движении матриц устроено приспособление, состо щее КЗ пропущенного поперек трубы, у ее переднего конца, пальца 18, вход щего своим концом в паз 20 стола устройства и служащего, кроме того, д.  зацеплени  за него т ги 19.The device for two-step drawing of pipes, shown in the drawing, consists of a bed 1 with bearings 2, 3 and 4 having detachable covers and serving to support the matrices 5 and 6 with different internal diameters, which are rotated using pins 7, 8. 9, 9. Heart 11, one end of which is held up by fork 14 of frame 15, carries at its other end two mandrels 12, 13 with different diameters. In order to prevent rotation of the pipe being processed during the rotational movement of the dies, a device is arranged consisting of a short circuit of a device that is passed across the pipe, at its front end, finger 18, entering with its end into the groove 20 of the device table and serving, in addition, to engage it nineteen.

Действие предлагаемого устройства дл  двуступенчатого волочени  труб следующее . Труба вставл етс  закатанным Концом в матрицы 5 и 6 и т гой 19 заЕ .П.The effect of the proposed device for two-stage tube drawing is as follows. The tube is inserted, rolled up, into the matrices 5 and 6 and on the late 19th of September.

цепл етс  за палец 18. Матрицы 5 и 6 привод тс  во вращение в разные стороны от шкивов 7 и 8, в то врем  как труба прот гиваетс  т гой 19.clings to the pin 18. The dies 5 and 6 are rotated in different directions from the pulleys 7 and 8, while the pipe is pulled by a pull 19.

Вращением матриц 5 и 6 создаетс  уменьшение сопротивлени  при волочении, что позвол ет производить эту операцию двум  ступен ми в один прием, чем достигаетс  ускорение процесса волочени . Одновременно получаетс  прокатка как наружной, так и внутренней стенки трубы, повышающа  механические качества еб.Rotation of the dies 5 and 6 creates a decrease in drag during drawing, which allows this operation to be carried out in two steps in one step, thus accelerating the drawing process. At the same time, rolling of both the outer and the inner wall of the pipe is obtained, increasing the mechanical qualities of the EB.

Предмет патента.The subject of the patent.

1.Устройство дл  двуступенчатого волочени  труб, характеризующеес  применением двух, с разными внутренними диаметрами, вращаю щихс  помощью шкивов 7, 8, матриц 5, 6 и двух соответствующих им и насаженных на одном сердечнике оправок 12, 13.1. A device for two-stage drawing of pipes, characterized by the use of two, with different internal diameters, rotating with the help of pulleys 7, 8, matrices 5, 6, and two matching mandrels 12, 13 mounted on one core.

2.При охарактеризованном п. 1 устройстве применение приспособлени  дл  предупреждени  от вращени  обра батываемой трубы при вращательнги  движении матриц, состо щее из пропущенного поперек трубы, у ее переднего конца, пальца 18, вход щего своим концом в паз 20 стола устройства.2. In the device described in paragraph 1, the use of a device to prevent rotation of the pipe being drawn during rotational movement of the dies, consisting of a pipe passed through the front end, finger 18, entering with its end into the groove 20 of the table of the device.
