Cons: impossible to manufacture panels of complex shape, for example with protuberances on the walls of the profile.

The closest technical solution known is the description of the patent USSR No. 452945, IPC B 21 D 13/10 from 25.08.72, published in Gazette No. 45 from 05.12.74, "Device for corrugating metal strip", ed. Edgar Vibe van. Dick (prototype), containing clips installed, with the possibility of a counter-movement in the plane of the tape, the restrictor clips and bending punch, equipped with a clamp placed between the clamps and having the ability to move perpendicular to the plane of the tape, and the mandrel having the ability to move across the tape.

Disadvantages: inability to obtain profiles of complex shape, for example with protuberances on the walls of the profile.

The technical result of the corrugations of complex shape is due to the fact that the device for the corrugation is of the metal strip, comprising upper and lower plates, clamps, installed with the possibility of a counter-movement in the plane of the metal strip, the bending punch, equipped with punch plate placed in her spring-loaded springs retainers, pilomatricoma, with grooves, wedges mounted on the top plate with the possibility of contact with pilomatricoma, pullers mounted on the top plate with the possibility of vertical movement in the slots of volumetric, U-shaped brackets mounted on the top plate, rocking chairs, swivel mounted on the punch plate and interacting with these spring-loaded clamps and wedges are mounted on U-shaped brackets below work surfaces volumetric along their axis of symmetry, with the possibility of contact with rocking chairs, the working surface of the bending punch is made in the form of a zigzag profile with ridges at an angle to the horizontal plane, and the working surface of volumetric made in the form of a longitudinal vertical halves specified zigzag profile, ridge which closed up are located relative to each other in a checkerboard pattern, while for fixation obtained flute after moving metal strip on one of polymetric performed a longitudinal projections with inclined and faces, one of which has a working surface in contact with the working surface of the bending punch.

Working surfaces of the bending punch is made in the form of a zigzag profile with ridges at an angle to the horizontal plane, and the working surface of volumetric made in the form of a longitudinal vertical halves specified zigzag profile, ridge which closed up are located relative to each other in a checkerboard pattern.

The location of the ridge at an angle to the horizontal plane allows to obtain the reliefs in the walls of the corrugations with greater depth, where reduced angle of inclination of the ridge increases the length of the ridge and, consequently, increases the length of the stretchable fiber material, which gives the possibility of obtaining the corrugations of the complex form.

To fix obtained flute after moving metal strip on one of polymetric performed a longitudinal projections with inclined faces, one of which has a working surface in contact with the working surface of the bending punch that allows fixation of the workpiece when moving it on the step. Such manufacturing corrugated parts with deep relief in the side walls enables more effective filler in sound-absorbing panels, for example, for aircraft engines.

The operation of the device

In the initial position the bending punch 6 with the upper plate 2 and the associated wedges 15, 16, U-shaped brackets 19 with wedges 21, the rods 17, 18 is in its upper position. The clamps 4 and 5 under the influence of the nuts 29 are also raised up, allowing you to apply the metal strip 1 in the area of stamping.

Advance metal strip 1 in the area forming step, equal to the length of the corrugations in the cross section in the scan.

During the course down the upper plate 2, along with other related details: wedges 15, 16, U-shaped brackets 19, wedges 21, the rods 17, 18, and nuts 29, the clamps 4 and 5 are omitted and press the metal strip 1 to pilomatrical 11, 12, the bending punch 6 suitable metal band 1 and touches it, and the wedges 15, 16 come into contact with pilomatricoma 11, 12. When moving the bending punch 6 wedges 15, 16 shift polimetrica 11, 12 are pressed thereto by a metal band 1 (blank) to the bending punch 6, allowing you to warp almost no stretching of the material. Along with this, the device provides a small tension of the metal strip 1 (0,2...0,5%) for a more precise design of the corrugations in the final stage of the stamping.

This is ensured by way of the delay offset volumetric 11 and 1 2 by adjustment of the angle of the wedges 15, 16 and volumetric 11, 12.

When moving volumetric 11, 12 to the plug 6 at the same time stamped (pressed) relief, in this case, the ridge 26 in the side walls of the metal tape 1 (procurement).

During the course of the upper plate 2 down with it down U-shaped brackets 19 with wedges 21, freeing rocking 20, which under the action of springs 8, 9 push the latches 10, locking volumetric 11, 12 at the end of the stamping, that is, when closing volumetric 11, 12 from bending punch 6.

During the return of the upper plate 2 bending punch 6, lifting, is withdrawn from engagement with the corrugation in the metal tape 1, the nuts 29 are lifting clamps 4 and 5, freeing the metal strip 1 and the wedges 21 jam on rocking 20, which sink clamps 10, and spring-loaded by a spring 30 polimetrica 11, 12 are moved apart, shifting in its original position.

Due to this design can be stamped in relief with more depth, so as to decrease the angle of the ridge 26 in the horizontal plane increases the length of the ridge 26 and, consequently, increases the length of the stretchable fiber material. The ridges 26 volumetric 11, 12 closed up are located relative to each other in a checkerboard pattern, which enables to reproduce the topography of the metal tape 1 without counter nataskivanie of the ridge 26 on each other.

To fix obtained flute after moving metal strip 1 on one of bolometric (polimetrica 11 figure 10) performed a longitudinal protrusions 27, 28 with inclined faces, one of which 28 has an active surface 22 in contact with the working surface 24 of the bending punch 6.

Longitudinal ledges 27, 28 (figure 10) are used for fixation of the metal tape 1 during operation of the device by fixing stamped corrugations between them after moving metal the ribbon 1 step each time before dieing.

The device is equipped with podsumowanie plate 7 placed in her spring-loaded (spring 8, 9) clamps 10, pilomatricoma 11, 12 with the slots 13, 14, the wedges 15, 16, fixed on the top plate 2 with the possibility of contact with pilomatricoma 11, 12, the rods 17, 18 mounted on the upper plate 2 can move in the slots 13, 14 volumetric 11, 12, U-shaped brackets 19 fixed to the upper plate 2, the jacks 20, pivotally mounted on a punch plate 7 and interacting with these spring-loaded clamps 10, and also wedges 21 mounted on the U-shaped brackets 19 below work surfaces 22, 23 volumetric 11, 12 along their axis of symmetry, with the possibility of contact with the beam 20 through slanted at the angle of the surfaces when they contact with each other.

Rocking 20 pivotally mounted on the punch plate 7 and are biased by springs 8, 9, attached to the clamps 10. The rods 17, 18 fixed to the upper plate 2, a vertically move in the slots 13, 14 volumetric 11, 12, raising or lowering the metal strip 1 at the time of operation of the device.
