Description

The invention relates to the processing of metals by pressure, in particular to devices for cutting pipes, and can be used in the blanking production of engineering departments for the production of pipe blanks.

The aim of the invention is to expand the nomenclature of the permitted by the device of pipes through the thickness of their walls,

The drawing shows a device for cutting pipes, a general view

The device for cutting pipes contains bases 1S, on which cutting discs 2 with drives 3 of their radial movement are placed in the same plane. Before cutting off the cutting board 1. with knives 2 on base 1, means for supporting the pipe being cut as base 4 with supporting rollers are placed 5, In case 6, a notched Diske knife 7 with a drive of 8 radial movement and supporting rollers 9 are mounted on both cTopoiib relative to an external disk knife 7, Cutting disk 2 and notched knife 7 are arranged in parallel lnpg; planes

A pipe cutting device works the following; in a scant way.

In the support rollers 5 and 9, install the cut pipe and attach

her rotation. By turning on the actuator 8, a notched disk knife 7 is brought to the pipe and the notched pipes 10 are made to form a groove,

5 The notched disk knife 7 is retracted to the initial position, after which the pipe is moved by a step equal to the distance between the planes of the position of the cutting and

10 notched disk knives, as a result of which the groove knurled on the pipe with knife 7 is located in the plane of the cutting disk knives 2. Then, the drives of 5 and 3 and 8 cutting 2 and notched 7 knives are simultaneously turned on and the radial movement of the cutting knives 2 and cut off from the pipe billet, and notch knife 7

20 forms in the pipe the next groove with

Due to the fact that the cut-off 2 and notch 7 circular knives are installed with an uppov m. Offset relative to the feed axis of the cut

pipes, made serious for cutting thick-walled pipes without jamming the circular knives.

In order to expand the nomenclature

30 half-finished workpieces along the length of the notched disk knife 7 are installed with the possibility of adjusting the pair 8 along 1-along the feed axis of the pipe being cut

Claims (2)

1. DEVICE FOR CUTTING PIPES into billets, comprising a housing, detachable cutting knives mounted in one plane mounted therein, and a notched circular knife located in a plane parallel to the plane of the cutting circular knives, a drive for radial movement of the circular knives and a means for supporting the cut pipe, characterized in that, in order to expand the range of cut pipes along the thickness of their walls, detachable and notched disc knives are mounted in a housing with an angular offset relative to the feed axis of the cut pipe s, wherein the drive radial movement of circular blades formed as individual for each power cylinder rods on which said disc knives mounted. 2. Device according to claim 1, characterized in that, with a view to extending the range of produced billets in length, _with nadreznoy dis- kovy knife mounted for movement along © adjusting the feed axis of the pipe being cut.
