Abstract

The invention relates to equipment for processing long materials and can be used for separation and molding forming operations. The goal is to improve the conditions of service. The device contains a rotor and a fixed cam 7. The rotor is formed by a drum 4 and a disk / D / 5. Matrices 9 are fixed on the D 5. In the grooves of the drum 4, when interacting with the cam 7, the sliders 13 move. The latter move the bodies / K / 11 through the springs 12 in which the punches are parallel to the axis of the rotor. At the same time, the wedges, which are in K 11, move the punches in the direction of radii D 5. They press the material to be machined to the dies 9 and perform a stamping operation. By 11, they are connected to the D 5 pivotally and when raising and lowering the sliders 13 rotate around the axes 21. 1 Cp. f-ly, 5 ill.

The invention relates to equipment for processing long materials and can be used for punching, cutting, drawing and other punching operations.

The purpose of the invention is to improve the conditions of service.

FIG. 1 shows the device, general view, plan; in fig. 2 shows section A-A in FIG. one . a first embodiment of means for connecting a punch with a cam; in fig. 3 shows a die, a punch and a mechanism for its radial movement in the first embodiment; in fig. 4 — another embodiment of means for associating a punch with a cam; in fig. 5 shows a die, a punch and a mechanism for its radial movement in another embodiment.

The device comprises a base 1, a coil 2 mounted on it, mounted on the shaft 3 and consisting of a rotor 6 and a disk 5 rotor 6 and fixedly mounted on the base 1 cam 7. The shaft 3 is connected to the drive through a gear 8 not shown). On the periphery of the disk 5, the matrices 9 are located. The punches 10 are installed in the housings 11 and are connected by means of elastic elements (springs) 12, poloshers 13 with rods 14 and rollers 15 with a cam 7. The polishers 13 are placed in the longitudinal grooves of the drum 4. The working windows of the dies 9 are located ejectors 16 equipped with springs 17. The punches 10 are equipped with springs 18. A wedge 19 and 20 are installed in the housings 11, which serve as mechanisms for the radial movement of the punches 10. In accordance with the first embodiment (Fig. 2 and 3) at the end of the rod 14 there is a shoulder, body 11 arnir- but mounted on an axis 21 fixed

pivotally mounted fork 23 and placed the plunger 24 with a spring 25.

In accordance with the second embodiment (Figs. 4 and 5), the body is made in the form of a bead 26 with a shoulder located in the groove 27 of the disk 6. In the body 11, a clamp 28 is installed, covering the punch 10.

The device works as follows.

The material to be processed from the coil 2 is continuously fed into the gap formed between the die 9 and the punch 10. The shaft 3, the drum 4, the disk 5, constituting the rotor 6, rotates continuously. In the first embodiment of the housing 11 in the initial lower position of the slider 13, the housing 11 is folded back to the position shown in FIG. 2 on the right. When the drum 4 and disc 5 are rotated, the slider 13 under the action of the cam 7 moves along the groove of the drum 4.

13 via the elastic element, in particular, the spring 12 of the fork 23 transfers the force to the axis 21 and the body 11, turning it around the axis until it contacts the material being processed and presses the latter to the matrix 9. After the body 11 is rotated, the pusher 24 closes with the slider 13 , moves the rod 14, moves the wedge 20 and 19 and the punch 10. The punch 10 makes a working stroke and, interacting with the matrix 9, forms the product. After the punching operation is completed, the slider 13 is lowered along the groove, the pusher 24 and the punch 10 released from the action of the rod 14 are returned to their original position by the action of the springs 18 and 25. The ejector 16 under the action of the spring

17 pushes the product out of the matrix 9. With further joint rotation of the rotor 6 and the body 11, the rod 14 continues to fall, loosening the compression of the spring 12, acts with a collar on the fork 23 and rotates the body 11 around the axis 21 at an angle allowing passage under the branch of the material being processed (Fig. 2 , right) Slider 13 occupies the starting position. Upon further rotation of the rotor 6, the cycle is repeated.

In the case of the second version of the housing in the form of a cup 26, the latter, at the moment of passage under the branch of the material being processed, is in the retracted lower position (Fig. 4, right). When the slider 13 moves upwards, the housing 26 under the action of the spring 12 moves in the slot 27 of the disk 5 parallel to the axis of the rotor 6 until it stops against the disk 5. At this moment the axis of the punch 10 is aligned with the axis of the matrix 9 (Fig. 5). The rod 14 through the wedge 20 and 19 transmits movement to the punch 10, and through the spring

18- on the clamp 28 and presses the material being processed to the surface of the matrix 9. Continuing its movement, the punch 10 makes a working stroke and forms the product. When moving the slider 13 down all the elements of the device occupy the initial position. Then the cycle repeats.

The technical effect of using the proposed device is to improve its service conditions.
