The aim of the invention is to increase the reliability of a pipe separation device. The piston 3 with the rods 4, 5, being stirred in the working position, will mix the stop 8. The spring 9 is compressed. A piston 12 with a rod 13 mixed, under the action of a spring 15 and the beveled surface of the rod 13 fixes the rod 5 to the end surface. Matrices 16, 17 are decompressed. The pipe 18 is fed axially to the required length and the previously cut billet 20 is pushed out of the matrix 16. The workpiece 20 is put on the rod 4 and rests on the end of the stop 8. After axial stirring, the pipe 18 of the matrix 16, 17 clamps the pipe and rotates the matrix 16 relative to matrix 17, the pipe is cut. The piston 12 with the rod 13 is retracted to the non-operating position, the spring 15 is compressed. Then the piston 3 with the rods 4, 5 is moved to its original position.

Description

The invention relates to the processing of metals by pressure, in particular to the separation of rolled metal, and can be used in the blank production of machine-building enterprises for the production of dimensional blanks by cutting rolled pipe.

The aim of the invention is to increase the reliability of the device for cutting pipes.

Fig. 1 shows a device for separation of pipes, a section, in a position of sub-interaction with an abutment 8. In the process of moving the pipe 18, the rod 4 keeps the mandrel 19 from axial interleaving. After moving the tube 18 of the matrix 16 and 17, the tube 18 is clamped and, by rotating the matrix 16, the tube is cut in the plane A. During the cutting process of the tube 18, the compressed air is fed into the cavity 14, the nopnienb 12 with the stem 13 is retracted to the non-operating position, the spring 15 is compressed , then the supply of szh15

chi cut pipe until it stops; In Fig. 2, the air in the cavity 7 of the piston 3 is the same in the position of separation and removal of the cut piece.

A device for separating pipes comprises a cylinder 1 with a cover 2, in which a piston 3 with rods 4 and 5 is mounted, forming working cavities 6 and 7. In the opening of the cover 2, an emphasis 8 is mounted in the form of a stepped sleeve, pressed into the non-working position by a spring 9. On the cylinder 1 is a tide 10 in which a cover 11 is mounted in a cylindrical bore and a piston 12 is installed with a rod 13, which is a locking rod 5, and a working cavity 14 is formed. The piston 12 is pressed into working position by a spring 15. The cylinder 1 is mounted coaxially to the cut-off dies 16 and 17 in which a pipe 18 is cut, in which, in the cutting zone, a mandrel 19 is installed. The diameter of the rod 4, which is a pusher, is set so that it freely enters the opening of the pipe 18 and secures the mandrel 19 from movement relative to the dies 16 and 17 in the process of axial movement of the pipe 18.

The device works as follows.

In the cavity 6 of the cylinder 1 serves compressed air. The piston 3 with the rods 4 and 5 is moved to the working position (Fig. 1) and moves the stop 8, while the spring 9 is compressed. The piston 12 with the rod 13 moves under the action of the spring 15 and the beveled surface of the rod 13 fixes the rod 5 beyond the end surface from possible movement. Matrices 16 and 17) are azzhat. The pipe 18 is fed in the axial direction at a length L along arrow B to

the rods 4 and b move to the initial position (figure 2).

The rod 4 is withdrawn from the pipe, the stop 8 under the action of the spring 9 also moves to its original position and releases the workpiece 20, which under its own weight falls into a discharge tray (not shown). After removal of the core 3 to the initial position, the cavity 7 is automatically connected with the external environment, which facilitates the retraction of the support 8.
