Abstract

DEVICE MOROZOVA G.A. FOR CUTTING PIPES containing a base, two knives, one of which is made in the form of a sleeve, and the other is associated with a rotational drive, characterized in that in order to increase productivity, the knife associated with the drive is made in the form of a disk consisting of two halves symmetrical with respect to the plane passing through the axis of its rotation; at the ends of each of which there are bevels converging toward this plane from the center of the disk to the periphery, and on the end surface of the sleeve there is a cut with a radius equal to the radius of the disk, axis disk rotation perpendicular to the axis of the sleeve.

Description

The invention relates to the processing of metals by pressure and can be used in engineering for cutting pipe ends along a radius.

The purpose of the invention is to increase the productivity of the device for cutting pipe ends.

Fig. 1 shows a device for trimming pipe ends in the initial position, a general view; in fig. 2 - the same plan; in fig. 3 shows section A-A in FIG. one.

The device for cutting pipe ends contains knives 1 and 2, the first of which is rigidly mounted on the drive shaft 3 (not shown). The knife 1 is made in the form of a disk, the end surfaces of which are made in the form of two symmetrical halves 4 and 5, each of which has a bevel to the periphery at an acute angle a to the plane 6 of longitudinal section. The knife 2 is made in the form of a cylindrical sleeve having from the end facing the knife 1, a notch 7 along a cylindrical generatrix with a radius equal to a given radius of trimming the pipe end and the radius of the circumference of knife 1, while the knife 2 is positioned so that its axis 8 of symmetry with the plane 6 of the longitudinal section of the knife 1 and perpendicular to the axis 9 of its rotation. In addition, the knife 2 has holes 10 for

installation eccentric schtifta replen on the bed 12.

and to prepare the device for operation, the knife 1 is installed so that one of the disk halves, for example half 5, is directed toward the end of the cylindrical sleeve in Fig. 2. The tube billet (shown in dotted lines) is inserted into the i ;;; knife 2 and with noMOiUbio eccentric shaft 11, rotating it around its own axis, pressing it to the stand until it stops on the disk, which will go into the tube billet just as far as the radius is necessary to cut the end of the pipe. Then, the drive is turned on, the rotational movement of which is transmitted through the shaft 3 to the knife 1. Since the working half of the disk of the knife 1, facing 2, knocks the end surfaces which are made with the bevel to the periphery, and the circumference: 1. highlander tsilnn. knife 2, then the disk, the incursion of the cutting edges 13 onto the pipe billet, begins to press the console, 1 pipe billet against the inner wall of the cylinder., the knife sleeve 2 n gradually. -jie.-u-irb wall the end of the pipe billet with .uvvx opposite sides, forming sy; metrichS

A low notch with a radius equal to the radius of the circumference of the disk of the knife 1. After making half a turn, the disk cuts the end of the pipe to a predetermined radius, after which the drive is turned off and the rotation of the disk of the knife 1 stops.

Then, turning the eccentric pin 11 and removing it from the holes 10 of the cylindrical sleeve of the knife 2, push the pipe with its cut off radius and the cycle repeats.

DEVICE OF MOROZOV G.A. FOR CUTTING THE END OF PIPES, containing a base, two knives, one of which is made in the form of a sleeve, and the other is connected with a rotation drive, characterized in that, in order to increase productivity, the knife associated with the drive is made in in the form of a disk, consisting of two halves symmetrical with respect to a plane passing through its axis of rotation, on the ends of each of which bevels are made, converging to this plane in the direction from the center of the disk to the periphery, and a cutout with a radius of an apparent radius of the disc, the disc rotation axis perpendicular to the sleeve axis.
