Abstract

The invention relates to the production of pipes and can be used in the line of continuous tube-welding mills. The aim of the invention is to simplify the design and reduce the metal consumption of a device for cutting moving tubes into measured lengths. The device comprises a frame 1, on the guides of which a trolley 2 is installed, carrying an adjustable end stop 3, a cutting unit in the form of a plasma torch 4, a mechanism for returning the trolley in the form of a rail 8. The pipe is cut, abutted against the stop 3, moves the trolley 2 until it interacts with a limit switch VK 1, which turns on the plasma torch 4. After cutting, pneumatic cylinder 12 is turned on, the rod 11 of which catches rail B and inlet. The billet on trolley 2 is retracted from the pipe being cut and reset by reset mechanism 13.

Description

I13

The invention relates to the manufacture of pipes and can be used in a line of continuous pipe welding mills.

The chain of the invention is to simplify the design and reduce the metal consumption of the device dp cutting moving pipes.

FIG. 1 shows a device for cutting moving tubes into measures of length, general view; in fig. 2 - the seizure of the trolley return mechanism at the moment of clamping in FIG. 3 - the same at the moment of unclamping.

The device for cutting moving tubes to measured lengths includes a frame 15 on the guides of which a trolley 2 is mounted, on which an adjustable end stop 3 is mounted, a plasmatron A, a trolley returning mechanism 5 and removing the cut billet, a billet dumping mechanism 6, 7. The carriage return mechanism 5 and removal of the cut-off workpiece includes a rail 8 connected via gear 9 to the wheelset of the carriage 2. At the end of the rail 8, a spring-loaded gripper 10 is mounted cooperating with the rod 11 of the pie-cylinder 12. The drive mechanism 6 drops the workpiece from hinged on the trolley 2 pneumatic cylinder 13.

The device works as follows.

The pipe, coming out of the mill, buttted against the stop 3, drags the cart 2 which, by pressing the limit switch VK1, switches on the plasma torch k. When the trolley is moving to the left, the piston of the pneumatic cylinder 12 is in the right edge position and the rail 8 moves away from the pneumatic cylinder 12. When the end switch BK2 is turned on, the plasma torch

enters, air is supplied to the right

pneumatic cylinder cavity. The rod 11, while moving, catches the rail 8 with the gripper 10, opens the gripping jaws, is gripped by them and begins to push the trolley 2 with the pipe cut off. Due to the fact that the speed of movement of the trolley is greater than the translational speed of movement of the pipe being rolled, the cut billet is moved away from the pipe, and the end switch of the VCR gives the command to supply air to the pneumatic cylinder 13, which actuates the lever system of the workpiece 6. After the cut off of the cut pipe, the end switches (not shown) are turned on and air from the pneumatic system enters the pneumatic cylinder 13, which returns the mechanism for resetting the workpiece to its original position. In this case, the lever 14 turns on the limit switch BK4, which gives a command for the return stroke of the pneumatic cylinder 12. The carriage 2 moves backward. When the rod 11 is moved, the grippers 10 of the slats 8 are driven into the wedge 15, unfold, and release the rod.
