A disadvantage of the known machine is the limited technological capabilities.

The purpose of the invention is the expansion of technological capabilities by providing processing pipes of various 15 diameters.

This goal is achieved due to the fact that the machine is equipped with a support element rigidly fixed to the spindle internal shaft and installed therein 20 perpendicularly to the spindle axis, with the possibility of rotation by an additional shaft kinematically connected to the spindle outer shaft, while the forming tool is mounted '5 with the possibility adjustment movement along an additional shaft.

A bevel gear 10 is attached to the outer shaft of the drive spindle, coupled to bevel gears 11 and 12, which are mounted on an additional shaft 13, on which the forming tool 14 is mounted. The shaft 13 passes through the support member 15, which is mounted on the inner shaft of the drive spindle by nuts 16. To adjust the position of the tool on the shaft 1-3, a set of interchangeable bushings 17 is installed.

The machine operates as follows: ‘After fixing the workpiece 18 in front of the drive spindle 3 with the forming tool 14, the electric motor b is turned on, which transmits rotation to the drive spindle through the V-belt 7 and gear 8 and 9 gears.

one . . The present invention relates to the processing of metals by pressure, in particular to machines for running. The known machine for running-in of tubular blanks, containing a spindle mounted on the frame, made in the form of internal and external drive shafts, and the Shchi tool form. A disadvantage of the known machine is the limited technological capabilities. The purpose of the invention is to expand those long-term possibilities by providing the liver with processing of pipes of different diameters. This goal is achieved due to the fact that the machine is provided with a supporting element rigidly fixed on the inner shaft of the spindle and mounted therein perpendicularly to the axis of the spindle with the possibility of rotation with an additional shaft kinematically connected with the outer shaft of the spindle, while the forming tool is installed with the possibility of adjusting nor along the additional shaft. FIG. 1 shows a machine, a general view; in fig. 2 - drive spindle. On the frame 1 in the bearing assemblies 2 mounted drive spindle 3 having an inner 4 and outer 5 shafts. These shafts are driven in rotation from the electric motor 6 through a long-time transmission 7 and gears 8 to 9 with different gear ratios. A conical gear 10 is mounted on the external shaft of the drive spindle and connected to the bevel gears 11 and 12, which are mounted on an additional shaft 13 on which the forming tool 14 is fixed. The shaft 13 passes through the supporting element 15 which is fixed on the internal shaft of the drive spindle by means of a nut 16. For adjusting the position of the tool on the shaft 1-3 a set of interchangeable bushings 17 is installed. The machine operates as follows. After securing the workpiece 18 in front of the drive spindle 3 with the forming tool 14, the electric motor b is activated, which transmits the rotation to the drive spindle via the V-belt 7 and the gear 8 and 9 gears. The gear train 9 transmits rotation to the outer shaft 5, on which a tapered gear 10 is transmitted by Zeplena, transmitting the rotation through wheel 11 to shaft 13, the Forming tool 14 is made ggak, which, when rotated around its axis, turns with its forming surface product profile. But since the workpiece is fixed, it is necessary to bring the tool into rotation around the axis of the workpiece. This is accomplished by gearing 8, which transmits the rotation to the internal shaft 4, on which the support element 15 is mounted. Through the element 15 passes the shaft 13 with the tool, which allows the tool to rotate with the shaft 13 around the axis of the workpiece. To adjust the position of the tool, a set of interchangeable sleeves 17 is provided, which can be easily changed on the shaft 13, displacing the position of the HHCfpyMeHTa along the axis of the shaft 13. Claims , and a forming tool, characterized in that, in order to expand technological capabilities, it is provided with a supporting element rigidly mounted on the internal spindle shaft and a perpendicular element mounted therein to the axis of the spindle rotatably additional shaft is kinematically associated with an outer shaft of the spindle, wherein the forming tool mounted for movement along an additional adjusting shaft.
