Description

one

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting pipes and tube blanks.

A device for cutting pipes is known, comprising a cutting disc with a drive for rotating it L1 J.

A disadvantage of the known device is its low productivity due to the considerable time spent on auxiliary tool movements and pipe feed.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by, j, that a device for cutting pipes, containing a cutting disk with a drive for its rotation, is provided with a guide that covers the cutting disk, installed with a variable clearance relative to the cutting disk, with a change in the gap size from the same pipe diameter to the difference between the diameter of the pipe and the thickness of its wall.

The curvilinear guide is made with a circular arc profile that encloses the cutting disk in an arc of 7G radians in length, and the axis of the arc of the circumference of the guide is eccentric with respect to the axis of rotation of the cutting disk with a value equal to half the wall thickness of the pipe being cut.

FIG. 1 shows a device with a circular arc-shaped guide, general view; in fig. 2 shows section A-A in FIG. one.

The device consists of a base 1 with a guide 2 fixed on it and a stand 3 with a cutting disk C mounted on it, the axis of which is located with an eccentricity a relative to the center of the arc of the guide. The disk is connected to the drive of its rotation (not shown). Plate 5, fixed to the end of the base, is an emphasis when cutting the pipe. In the case of separation of a small pipe length 394

Cooking in two parts of the same can be installed on the other side of the base at a corresponding distance from the top of the cutting deck. The device also includes a loading device I, not shown with tray 6, and a drum to ensure the axis of the pipe being cut is parallel; axis of rotation of the disk (not shown).

The device works the following. About.

The pipes to be cut or pipe blanks 7 from the loading device on the tray alternate between the guide 2 and the cutting plate C, which is transmitted by a special drive. Blade of the cutting disk (presses the pipe to the guide and draws it into the gap between them, Los1;; as the gap between the guide 2 and the cutting disk 4 gradually decreases, the blade of the disk penetrates into the pipe wall, rolls it along the guide the resulting force of friction and cuts. In this way, several pipes are cut simultaneously, while the auxiliary elements are carried out simultaneously with the pez-kk process.

The technical and economic effect of the use of the proposed device for the south consists in increasing: 1 1 - e - and performance for a non-burst cutting machine at the same time: 1l1 - x
