Abstract

The invention relates to equipment for pressure treatment of material in the form of wire or tape and can be used in the electrical and metalworking industry. The purpose of the invention is to expand the range of products manufactured by obtaining products with variable pitch between the corrugations and flat areas between them. The device contains a lifting base (O) 1 with guides 2 and bending heads (G) 3 and 4. A lever (P) 5 or 6 is pivotally connected to each G. P 5 and P 6 are pivotally connected to each other. on guides 2. They pull together GZ and G4 and they form a loop from the wire or tape being processed. After mutual fixation of GZ and G4, they move together a step. O 1, P 5 and P 6 are lowered and the wires or ribbon G 3 and G 4 are released to their original position. To obtain products with flat sections between the corrugations, the cycle of clamping the material — moving G 3 and G 4 — lowering O 1 with P 5 and P 6 is repeated several times. 2 hp f-ly, 8 ill. sl C

A device for making zigzag products comprises a base 1 with guides 2, on which bending heads 3 and 4 are mounted for movement. On bending heads 3 and 4 and 25, the arms 5 and 6 are hinged respectively and are connected by a hinge 7.

On the axis of the hinge 7 and the hinges 8 and 9, linking the levers 5 and 6 to the bending arms 3 and 4, the bending templates 10 are placed. and corresponding to it 35 holes 12 in the bending head 4. In addition, the device is equipped with a means of fixing one of the bending heads relative to the guide 2, made in the form of a v-shaped bar 13 with projections, 40 the distance between the axes of which is equal to the distance between guide axles 2, Pla Single 13 provided with individual movement drive 14 (Figures 1 and 6). In order to move the strip 13, grooves 15 are provided in the protrusions 11 45 of the bending heads. The bending heads 3 and 4 have a movement actuator 16. In places of articulation of the levers 5 and 6 are located the stops 17, mounted rotatably with respect to the axes 50 of the templates 10. On the bending head 3, clamps 18 are placed.

A device for making zigzag products can be embedded in automated pinia containing 55 unwinding 19, correct 20, heating 21 and calibrating 22 devices, device 23 bending the branches of the obtained product, cutting device 24 and receiving platform 25 (FIGS. 4 and 5) .

A device for producing zigzag products operates as follows.

The wire or tape from the unwinding device 19 passes through the correct device 20 and is fed to the device for receiving zigzag products. The heating devices 21 are lowered, the bending sections of wire or tape are heated, and at the same time the wire or tape is aligned with the axes of the templates 10. The bar 13 fixes the position of the bending head 4 relative to the guides 2, and the drive 16 begins to move the bending head 3 towards the bending head 4. As a result, loops (fig. 3) are formed from a strip or a tape and bending of the wire or tape relative to the axes of the bending patterns 10. In this case, the stops 17 roll around the axes of the patterns 10.

When approaching the bending heads 3 and 4 adjustable protrusion 11 enters the hole

12. The bending head 3 acts on a limit switch (not shown), a command is given to the actuator 14 for moving the bar.

13, it fits into the groove 15 and mutually fixes the bending heads 3 and 4. Next, the bending heads 3 and 4 move together one step. The base 1 and the levers 5 and 6 are lowered and the stops 17 are brought out of contact with the material being processed. The tape is bent or the wire enters the receiving platform 25. The calibration device 21 is lowered and calibrated. The actuator 16 moves the heads 3 and 4, fixed by the strap 13, to its original position. Clips 18 pick up the material being processed, strap 13 is moved to its original position and fixes the bending head 4 relative to the guides 2, and the actuator 16 returns the bending head 3 to its original position and moves the processed piece of material a step. If necessary, a cycle including clamping the material, moving the heads 3 and 4 and lowering the base 1 with the levers 5 and 6, is repeated the required number of times. As a result, a flat section is formed between the zigzags (corrugations), the length of which is a multiple of the displacement step of the heads (Fig. 7). The device also allows to obtain products with inclined branches (Fig. 8).

The proposed device provides for the expansion of the range of products obtained, since it ensures the production of products with a constant and variable pitch between the corrugations, as well as products with both parallel and inclined branches.
