Изобретение относитс  к области обработки металлов давлением.This invention relates to the field of metal forming.

Известно устройство дл  изготовлени  полых изделий давлением рабочей среды, содержащее матрицу с конической рабочей поверхностью и со сквозными отверсти ми дл  удалени  воздуха между заготовкой и матрицей и концентрично расположенную в ней оправку с отверсти ми дл  подачи рабочей среды в полость заготовки.A device for the manufacture of hollow articles by pressure of a working medium is known, which contains a matrix with a conical working surface and with through holes for removing air between the workpiece and the matrix and a mandrel with holes for concentrating the working medium in the cavity of the workpiece located concentrically in it.

Однако герметизаци  такого устройства достаточно сложна.However, sealing such a device is quite complicated.

С целью упрощени  конструкции в предлагаемом устройстве оправка установлена с возможностью осевого перемещени  в процессе деформировани , а ее рабоча  часть выполнена с цилиндрическим и коническим участками, суммарна  длина которых равна длине трубки-заготовки, а наибольший диаметр конического участка равен наибольшему диаметру готовой трубки.In order to simplify the construction in the proposed device, the mandrel is installed with the possibility of axial movement during the deformation process, and its working part is made with cylindrical and conical sections, the total length of which is equal to the length of the billet tube, and the largest diameter of the conical section is equal to the largest diameter of the finished tube.

На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.

Деформируемую трубку (тюбик) 1, снабженную пробкой 2, закрепл ют на оправке 3, в которой выполнены канал а и отверсти  б, по которым сжатый воздух (рабочую среду) подают в полость трубки.A deformable tube (tube) 1, provided with a stopper 2, is fixed on a mandrel 3, in which a channel a and apertures b are made, through which compressed air (working medium) is fed into the cavity of the tube.

Оправка 3 помещена в 4 с конической рабочей поверхностью и с каналами в дл  выхода воздуха.The mandrel 3 is placed in 4 with a conical working surface and with channels in for air outlet.

Оправка 3 крепитс  на полом стержне 5, совершающем пр молинейное возвратно-поступательное движенпе под воздействием домкрата 6, и имеет рабочие цилиндрический А и конический Б участки, причем суммарна  длина их равна трубки-заготовки, а наибольший диаметр конического участка Б равен наибольшему диаметру готовой трубки.The mandrel 3 is mounted on the hollow rod 5, which performs a rectilinear reciprocating movement under the influence of the jack 6, and has cylindrical A and conical B sections, the total length of which is equal to the blank tube, and the largest diameter of the finished tube .

Воздух, вводимый через полый стержень 5 по каналу а, нагнетаетс  в оправку 3, и трубка 1 прижимаетс  к внутренней стороне матрицы 4. Под воздействием домкрата 6 оправка 3 продвигаетс  вперед и компенсирует расширение отверсти  основани  и укорачивание длины трубки, осуществл   герметизацию последней .The air introduced through the hollow rod 5 through the channel a is injected into the mandrel 3, and the tube 1 is pressed against the inner side of the matrix 4. Under the influence of the jack 6, the mandrel 3 moves forward and compensates for the expansion of the base opening and shortening the tube length by sealing it.
