Abstract

The invention relates to the processing of metals by pressure, in particular, to devices for changing the diameters of the ends of pipes. The purpose of the invention is to increase productivity and quality. The device contains a rolling head 1, carriages 4 and 5 with semi-matrixes (PM) 8 and 9. At the ends of PM 8, there are guides and stops 17, which interact with grooves and fingers 18 of PM 9. Pipe (T) 34 are inserted into the working area up to the stop 17. By means of the drive, PM 8 and 9 are reduced, clamping T 34. The protrusion on PM 8, inserted into the groove, provides rigid fastening T 34. Stop 17, interacting with the finger 18, moves, providing access to the rolling head 1. If necessary reconfiguration of the device for processing pipes of different diameters PM 8 and 9 are diluted with a protrusion of the groove and manually rotated to mate the two identical slots whose diameter corresponds to the diameter of the pipe. 4 hp f-ly, 5 ill.

Phie.1

The invention relates to the processing of metals by pressure, in particular, to devices for changing the diameters of the ends of pipes.

The aim of the invention is to improve productivity by reducing installation time and improving the quality of the flare.

FIG. 1 shows the ycTjioiicTBo for flaring, general view; in fig. 2 view A H: I of FIG. one; in fig. 3 - section B B on. I; in fig. 4 - section B - B in FIG. 2; on phi 5 a section G - G on fig. one.

The device for flaring contains a roll head 1 with a rotational drive and axial non-displacement (not shown), case 2. In the guides 3 of which are placed carriages 4 and 5. the bearing axes b and 7. On the latter, MHOI-O are nested semi-matrices 8 and 9. On the semi-matrix 8 sch) sides of the inner end, the strips with BiiicTyna guides I) with holes 11 are separated, and on the semi-matrix 9 grooves 12, one feature one) 1z of the projections 10 are inserted into groove 12. (|) 11xir snag two of the same double-sided matrixes 8 and 9. The holes 11 are made in the form of intersecting circular holes 13 and 14. Different diameters. The holes with a smaller diameter 13 coaxially to the nests of the half-matrix 8. The fastener 15 is fastened to the outer last one, in which are placed the springs 17, which are spring-loaded with springs 16, which can interact with the fingers 18 fixed on the one-minute) 9. The distance from the working surfaces iiopoB 17 to luiiixca 19 of the v. parting head 1 in its extreme working position is directly proportional. p.pie dm-meter.

The carriages 4 and 5 are connected by n, i;, fii4M 2i), the slats 21 and HiecTepim 22 are connected to the ipoc 23 pnevmotsi.shndra 24. In hiroke

The carriages 4 and 5 are equipped with sub-grids with fixed locks |) 31. installed with the possibility of interaction with nests of 32. B1 is filled in axes 6 and 7.

The device works in the following way.

In the original application, Karelki 4 and 5 are divorced, with a fout of 1NOTK 23 through springs

26, the pusher 27, the roller 28 interacts with the step 33 of the slide 29 and 17 overlaps the valve i nezda. The pipe is 34 hours long (a recess 13 is inserted into the working zone up to the stop 17. Then by means of a tube).

24, the cages 4 and 5 are reduced, semi-matrices 8 and 9 clamp the pipe. With a good pore 17. interacting with the finger 18, it moves to align the axis of the hole 35 made in it with the axis of the socket. Roller bushing 1 through hole 35 is inserted into the pipe, the flaring process is carried out. After flaring, the head I and the carriages 4 and 5 with the half matrices 8 and 9. And also the stops 17, under the influence of the spring 16, rotate to the initial position. After processing the first pipe through ogr-pc-ee 14, it is removed from the device (.st., At the next stage of expansion);

g, diameter) and the cycle repeats. If necessary, the flaring of pipes of another diameter of the cylinder 30 of the slider 29 is moved to the upper position, the roller 28 comes into contact with the group 36 of the slider 29. Semi-matrices 8 and 9 are separated, and the protrusion 10 comes out

5 1GZ of the groove 12. The semi-matrix 8 and 9 are turned to mate two identical nests, the diameter of which corresponds to the diameter of the pipe being processed. In the case of 1ol (), a mat. Mat) is fixed by means of fixers 31. Che) Without opening 13, the treated coarse 34 is inserted into the working area up to the stop 17. The cylinder 24 of the carriage 4 and 5 of the pulley). the protrusion 10 is inserted into the groove 12 and the floor of the matrix is clamped to the pipes.
