Abstract

The invention relates to the processing of metals by pressure, in particular, can be used in mechanical engineering for cutting pipes into dimensional workpieces. The purpose of the invention is to increase productivity and reliability. A bar is fed to the device. Turning on the actuator head 7 is reported to rotate. After the shaft 40 is moved in the axial direction, the elements 9, 10 rotate the crankshafts 11c with the journals 14, 15, move the sliders 16, 17 relative to each other in the opposite direction. The axes of rotation of the cutting rings 22,23 are displaced eccentrically relative to the axis of rotation of the head 7, and the cutting edges of the rings are inserted into the wall of the pipe 50. Due to the frictional force between the pipe 50 and the cutting rings 22, 23, the latter is rotated together with the sleeves 20, 21. in which the cutting edges of the rings 22, 23 roll around the wall of the pipe 50. 7 Il.

SUMMARY OF THE INVENTION A device for cutting pipes, comprising a housing, a pipe clamping mechanism, a cutting head made in the form of a spindle carrying a slider, a sleeve mounted therein with a 20 rotation-free possibility thereon, a cutting tool fixed therein, made in the form of a flat ring with an inner a one-sided cutting edge located in the plane of its end face opposite to the end face of the sleeve, and the radial mechanism. moving the slider, characterized in that in order to increase productivity and reliability, it is equipped with an additional slider arranged coaxially with the existing slider and an additional slider installed therein and arranged with a cutting tool arranged to interact with its flat end with the mating surface of the cutting the tool of the existing slider, the mechanism of radial movement of each of the sliders is made in the form of a pair of crankshafts placed diametrically opposite in the w pindel, wherein the eccentricity of the crankshaft journals with the existing slider mounted on them is directed diametrically opposite to the eccentricity of the crankshaft journals with the additional slider mounted on them.
