Abstract

The invention relates to the medical industry and allows to expand the technological capabilities due to the possibility of cutting thin-walled rings of large diameters from elastic tubes and installing the rings on the reinforcement due to their stretching. The flexible tube 2 is pressed by the jaws of the gripper 10 to the straightening piston 22 and is moved forward by the gripper 10. At this time, the tube 2 slides along the sleeve 24, aligns and is put on the blades 23 of the collet 15. Then the petals 28 are diluted, the jaws of the gripper 9 press the tube 2 to the sleeve 24, and the pusher 14 returns the piston 22 to its original position. Further, the rotation of the cutting mechanism 11 is reported and the knife 12 cuts off the ring 1 from the tube 2, expanded by the petals 28 of the collet 15. At the same time, the gripper 10 returns to its original position and its jaws again press the tube 2 to the piston 22. At the same time, At the lower position of this mechanism, the ejector 16 moves forward and the previously cut off ring 1 is placed on the armature 3. Then the reels 5 and 13 are rotated 180 °, the cycle of the automaton is repeated. 2 Il.

Description

The invention relates to technological equipment and can be used in the medical industry.

The aim of the invention is the expansion of technological capabilities due to the possibility of cutting thin-walled rings of large diameters from elastic tubes and installing rings on the reinforcement due to their tension.

Figure 1 shows the machine, a General view; figure 2 is a section aa in figure 1.

The machine for cutting rings 1 from an elastic tube 2 and assembling them with reinforcement 3 comprises a reinforcement 3 feeding mechanism 3 mounted on a base 4 in the form of a rotary drum 5 with sockets 6. inlet 7 and 8 outlet trays, the elastic tube supply mechanism 2 in the form of a fixed 9 and rolling 10 grips, a cutting mechanism 11 with a knife 12 and an assembly mechanism in the form of a rotary drum 13, in the openings of which are located coaxially arranged pushers 14, collets 15 and shedders 16. as well as a cam command device 17 kinematically connected with the said mecha isms, and drive '18. The drive of the gripping jaws of the grippers 9 and 10 is made in the form of eccentrics 19 and 20. respectively, located on the rotary axis 21. Between the gripping jaws of the grippers 9 and 10 inside the tube 2 there is a straightening mechanism of the tube 2 in the form of a piston 22, on the rod 23 of which the sleeve 24 is freely mounted . Inside the drum 13, fixed support 25 and fixing 26 drums are installed, and the collets 15 are made in the form of a sleeve 27 and petals 28.

The machine works as follows.

The dressing mechanism is installed in the hole of the elastic tube 2, after which the end of the tube 2 is inserted between the tongs of the tongs

9. 10 to the knife 12. When you turn on the machine, the petals 28 of the collet 15 are reduced, and the sleeve 27 is moved all the way into the sleeve 24 of the dressing mechanism. Then the tong 10 moves forward. In this case, the jaws of the tong 9 are divorced, and the tube 2 is pressed by the lips of the tong 10 to the piston 22 and moves forward with the tong. sliding on the sleeve 24, due to this, the tube 2 is aligned and put on the petals 28. Next, the axis 21 is rotated, the tongs of the tong 9 are reduced and clamp the tube 2. and the lips of the tong 10 are divorced. At the same time, the collet petals 28 are pulled apart and open the end of the tube 2, and the pusher 14 moves forward and returns the piston 22 to its original position. Then the pusher 14 is retracted, and the cutting mechanism 11 receives rotation and with a knife 12 cuts off the ring 1 from the tube 2, worn on the petals 28 of the collet 15. At the same time, the gripper 10 returns to its original position, its jaws are reduced when turning the eccentric 20 and again press the tube 2 to the piston 22. Simultaneously with the start of operation of the upper position of the assembly mechanism, the ejector 16 at the lower position moves forward and the previously cut ring 1 is mounted on the valve 3. After the operation of the assembly mechanism is completed, the drums 5 and 13 rotate 180 °. In this case, the cut off ring 1 is transferred to the lower position of the assembly mechanism, and a new reinforcement 3 enters the socket 6 of the drum 5.

Next, the cycle of the machine is repeated.
