Description

(54) PIPE CUTTING DEVICE

one

The invention relates to mechanical engineering and can be used to cut pipes into blanks.

According to the main author. swith No. 538828, a pipe cutting device is known, comprising a tube clamping mechanism mounted in a housing and kinematically connected to each other and a cutting head in the form of a rotating faceplate, on which spring-loaded cutting tools interacting with the inner surface of the annular are installed with radial back-to-post movement. a copier mounted on a plate that can be rotated from an individual drive, made in the form of electromagnets, fixed in the case evenly around g copier (1).

During operation of this device, the copier is heated to 100-120 ° C and, as a result of this, the temperature broadening of the copier to 0.2-0.25 mm, which causes vibration, skewing of the copier along the axis of rotation and its jamming over the outer diameter the stator poles of electromagnets, i.e., the reliability of its operation decreases.

The purpose of the invention is to increase the reliability of the device.

The goal is achieved by the fact that a pipe cutting device containing a pipe clamping mechanism mounted in a housing and kinematically interconnected and a cutting head in the form of a rotating plate, on which spring-loaded cutting tools interacting with the inner surface are installed with the possibility of radial reciprocating movement ring

10 copier mounted on the faceplate can be rotated from an individual drive, made in the form of electromagnets, fixed uniformly around the copier in the case, fitted with an insert mounted by means of support plates with the possibility of turning the sleeve with an impeller on it, and the copier mounted on the sleeve and made with central and radial through holes.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3- section BB in FIG. 2

The device e; 1 pipe cutting includes a housing 1, a bearing spindle 2 with a pulley 3. At the front end of the housing 1, an electromagnet case 4 is mounted, covering the face plate 5 installed on the front end of spindle 2, on which two shoulders are attached, axle b one shoulder contact rollers 7, and on the other shoulder cutting discs 8. Contact rollers 7 interact with copier 9, st -. bath with the faceplate by means of the spring 10. A stop 11 of its rotation is installed on the camcorder, periodically in contact with the groove 12 of the faceplate 5. To return the levers 6 to the initial position, a spring 13 is provided mounted on the lever ah and rests against the stops 14 of the shaft 5. Around the bridge 9 6 Kupfiyce 11 electromagnets are installed 15. Copier 9 is mounted on the faceplate 5 by means of a support made in the form of a sleeve 16 fixed rigidly in the central opening of the console of the copier, mounted through bearings 17 on the faceplate 5. On the cylindrical side The sleeve of the sleeve 16 is fixed to the wing 18. In the flange of the copier 9, ventilation channels 19 are provided.

The device works as follows.

V-belt drive (not shown) spindle 2 together with faceplate 5, levers 6, contact rollers 7, cutting discs 8, spring 10, copier 9 with sleeve 16 fixed on it, impeller 18 rotates around cut off iGtoBKK (not shown) with a fixed angle by speed. When the electromagnet 15 is turned on between bolts 4 and copier 9, a magnetic force field arises, braking the copier 9, as a result of which the faceplate surpasses the copier 9. The contact rollers 7, roaming the copier 9 of the copier 9, turn the levers 6 to perform working cutting discs 8. There is a piece of workpiece. The faceplate 5 overtakes the copier 9 until the stop 14 comes into contact with the groove 12 in the faceplate 5, after which the faceplate 5 and the copier 9 rotate together, overcoming the resistance of the magnetic field. When you turn off the electromagnets 15 spring 10 returns the copier 9 to its original position, and the spring 13 returns to its original position the levers 6, using this centrifugal force arising from the masses of the levers.

The cycle is repeated.

When the device is in operation, the impeller 18, constantly rotating, blows the outer surface of the copier 9 n through the channels 19 to the inner surface of the console of the copier 9 and sleeves 16, preventing the parts from heating.

The device of this design has a high reliability.
