Abstract

The invention relates to equipment used for gas-flame cutting of pipes, in particular for cutting pipes at right and sharp angles with simultaneous chamfering. The purpose of the invention is to improve the quality of the cut. The axes of the rollers 3 are located in a horizontal plane at an angle to the feed direction of the pipe being cut (T) 10. When T 10 rotates by rollers 2, a force arises at the contact points T 10 with rollers 3 that through the spindle 15, the axis 13 of the bearing, the bearing 14, the bracket 16 The carriage 7 and the stopper 9 are transferred to the frame 1. This ensures that T 10 is held against axial displacement, which can be caused by inaccuracies in the installation of the drive rollers 2, as well as deviations of the geometrical shape T 10. 4 Il.

The invention relates to equipment for gas-flame processing, in particular for cutting pipes at an angle with simultaneous chamfering.

The purpose of the invention is to improve the quality of the cut.

FIG. 1 shows a device for cutting pipes, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The device works as follows.

The rotation of the tube 10 is carried out by the driven rollers 2 on which the machined tube 10 is mounted. The mechanism for controlling the cutter 19 is driven from the rotating tube 10 to the outer surface of which the roller 20, kinematically connected to the cutter 19, is pressed.

In order to prevent the movement of the device, the cutting device for the pipe contains the axial direction of the pipe 10, the mu I with two pairs installed in connection with the inaccuracies of the mounting of the supporting rollers 2, as well as

supporting rollers 2 and 3. Moreover, the rollers 2 located on the cutting side of the pipe are driven and supported on frame 1. The drive of rollers 2 contains an electric motor 4, a gear 5 and a worm gear b.

The rollers 3, located on the side opposite to the cut pipe, non-driven and mounted on the trolley 7. Trolley frame 7

the deviations of the pipe 10 from its regular geometric shape, the axis of the rollers 3 are rotated in terms of the axis of rotation of the pipe 10 being processed. Therefore, when the pipe 10 rotates through the rollers 3, a force appears along the axis of the pipe 10 in one direction, which spindle 15, axle 13, bearing supplied with wheels 8 for moving nick 14 each, bracket 16 and stopper 9 is transmitted

on the frame 1. At the same time, the pipe 10 is kept from axial displacement, i.e., the pipe is cut in a high-quality manner.

Claims (1)

Invention Formula frame I when setting up to perform a pipe cut and a stopper 9 for fixing the relative position of the frame of the carriage 7 relative to frame 1 when performing a pipe cut. Inside the treated pipe 10, from the side opposite to the cut, there is a spacer of the tee shaft II. The ends of the rod are threaded, and the tips 12 are screwed on them to unlatch the rod in the pipe 10. The rod II is connected to the axis 13 of the bearing 14 by means of a spindle 15. The bearing 14 is installed in the groove of the bracket 16 fixed to the frame of the trolley 7 and therefore rigidly connected with the supporting rollers 3. The axes of the rollers 3 are set at an angle to the axis of rotation of the pipe 10. The bracket 16 35 together with the rollers 3 connected with it through the frame of the trolley 7 can move along the frame 1. On the latter column 17 is fixed with a mechanism 18 for controlling the position of the gas or plasma torch 19, receiving a reciprocating motion from the leading gear roller 20, rolling without slipping on the surface of the pipe 10.

Frame G is made of two parts, connected by means of a hinge 21, which simplifies its manufacture, precise installation and alignment at the place of operation, as well as transportation of a device intended for the treatment of long pipes (up to 9 .1). The device works as follows. The rotation of the pipe 10 is carried out by the driven rollers 2 on which the machined pipe 10 is mounted. The mechanism for controlling the cutter 19 is driven from the rotating pipe 10 to the outer surface of which the roller 20, kinematically connected with the cutter 19, is pressed. To prevent the rotating tube 10 from moving axially in connection with the inaccuracies of the tube 10 from its regular geometry, the axes of the rollers 3 are rotated relative to the axis of rotation of the processed tube 10. Therefore, when the tube 10 rotates through the rollers 3 at the points of their contact, a force arises, directed along the axis of the pipe 10 in one direction, which through the spindle 15, axis 13, bearing five A device for cutting pipes, which contains a frame, a mechanism for rotating the pipe being cut, a cutting mechanism mounted on the frame, and supporting rollers, characterized in that, in order to improve the quality of the cut, it is equipped with a mechanism for axial fixation of the pipe during its separation, in the form of a trolley mounted on a frame with the possibility of reciprocating movement in the direction of supplying the pipe to the cut, a bracket with a groove made therein mounted on the trolley, a bearing mounted in the groove of the bracket coaxially with the direction supply of the pipe being cut with the possibility of adjusting the movement in the vertical direction, the bearing axis installed in the inner bearing ring, the spacer P1tangi, the spindle pivotally connected at one end to the bearing axis and the other with the spacer bar, and the stopper of the cart, with the rotation mechanism being cut the pipes are made in the form of driving rollers, the supporting rollers are mounted on the trolley, and their axes are located in a horizontal plane at an angle to the feed direction of the cut of the pipe. five fig, g sixteen fig.z FIG.
