Изобретение относитс к заготовительному производству машиностроительных заводов , и может быть использовано при разделении труб.The invention relates to the blank production of engineering plants, and can be used in the separation of pipes.

Известно устройство дл разделени труб кручением, содержащее станину со смонтированными на ней с возможностью вращени в разные стороны узлами зажима трубы и отдел емой от нее заготовки в виде приводных шпинделей с клиновыми зажимами 1.A device for separating pipes by twisting, comprising a frame with mounted on it rotatably in different directions, pipe clamping units and a workpiece separated from it in the form of drive spindles with wedge clamps 1.

Недостатками известного устройства вл ютс невысокие производительность и качество торцов получаемых заготовок.The disadvantages of the known device are low productivity and quality of the ends of the obtained blanks.

Цель изобретени - повышение производительности и качества торцов получаемых заготовок.The purpose of the invention is to increase the productivity and quality of the ends of the obtained blanks.

С этой целью в устройстве дл разделени труб кручением, содержащем станину со смонтированными на ней с возможностью вращени в разные стороны узлами зажима трубы и отрезаемой от нее заготовки в виде приводных, щпинделей с клиновыми зажимами , зажимы зажимных узлов расположены эксцентрично относительно осей шпинделей , привод каждого зажима выполнен индивидуальным, а привод каждого щпиндел - в виде силового цилиндра с зубчатой рейкой, и зубчатого колеса, смонтированного на шпинделе с возможностью взаимодействи с указанной рейкой.For this purpose, in a device for torsion pipe separation, which contains a frame with mounted on it rotatably in different directions by the tube clamping units and the workpiece cut off from it in the form of drive chucks with wedge clamps, the clamps of the clamping nodes are eccentrically relative to the axes of the spindles; the clamp is made individually, and the drive of each pin is in the form of a power cylinder with a gear rack, and a gear wheel mounted on the spindle with the ability to interact with the specified rail.

A device for separating pipes comprises a bed 1, on which a left spindle clamping unit 2, a right spindle clamping unit 3, re-pinch drives of spindles 4, sources of rotational force of spindles - pneumatic cylinders 5 and a mechanism 6 for feeding the cut pipe are mounted. Use of pneumatic cylinders in

15 as the source of the force of rotation of the spindles gives them a sharp turn, which is important for a high-quality cut. The clamping units of the device are identical in design and each of them contains the housing of the sub-bearing support 7, in which a spindle 9 is installed on rolling bearings 8. A spindle 9 is mounted on spindle 9, which from the pneumatic cylinder sends a reverse angular movement to spindle 9 through the rail 11. The final positions of rotation of the spindle 9 are provided with screw stops along the rail 11 (not shown). The adjusting axial movement of the spindle 9 performs a threaded stop 12 mounted in the rear cover 13 of the bearing support housing 7, which through the thrust bearing 14 presses the end of the 9 screw. At the projecting threaded end of the spindle 9, whose axis is offset relative to the axis of rotation, a special thread is installed the nut 15, which with the inner conical surface holds the special collet (collet clamp) 16, pressing it against the spindle nose 9. The eye of the special threaded nut 15 is pivotally connected to the pneumatic cylinder stem plug 17, which is hinged on the bracket 18 mounted on the sharpening of the spindle 9. The pneumatic cylinder 17 informs the special threaded nut 15 of the angular reversing movement. A pipe feed mechanism 6 is fed through the spindles 9 and the collet 16 up to the stop (outside the machine) to obtain the desired length of cut. Air cylinders 17 are turned on, which are connected to the lugs of threaded nuts 15 with a large thread pitch with their rods and turn the nuts 15, which, having made axial movements, compress the collet 16 with their internal cones, crimping them around the pipe surface. The angle of rotation of the spindle 9 can be adjusted by the stroke of the rails 11, which is determined by the quality of the pipe material. After the pipe has been cut, the pneumatic cylinders 5 and 17 are switched simultaneously. The return of the spindles 9 to its original position, the removal of the threaded nuts 15 and the unclamping of the collet clamps 16 under the influence of the elastic forces of the collets. To make a new cut, the cycle is repeated. The design of the proposed pipe separation device has high productivity and allows to improve the quality of the ends of the obtained blanks. Invention Formula. for separation of pipes by torsion, comprising a frame with mounted on it rotatably in different directions by pipe clamping units and a workpiece separated from it in the form of drive spindles with wedge clamps, characterized in that, in order to increase the productivity and quality of the ends of the resulting blanks, clamps the clamping nodes are located eccentrically with respect to the axes of the spindles, the drive of each clamp is made individually, and the drive of each spindle is in the drive shaft from the toothed cylinder. rack and gear mounted on the spindle with the ability to interact with the specified rail.
