The invention relates to the processing of metals by pressure and can be used in the manufacture of wire rods and pipes of ferrous and non-ferrous metals.

A device for deforming a metal with the use of oscillations, including a fiber mounted in a fiber holder and placed in front of it in a fixed case, a self-braking wedge clamp for metal 1, is known.

The disadvantages of the known device are the complexity of the design due to the presence of a separate traction member for carrying out the metal working process, its low productivity due to the fact that the fixed wedge clamp is - passive in the metal working process and its application is weak. It affects the reduction of the dragging force, as well as the fact that the device contains only one deforming unit (dragging with a wedge clamp for metal).

A device for deforming a metal using oscillations is known, including a fiber installed in a vibration holder, a self-braking wedge clamp placed in front of a wok in a stationary case, and an additional wedge assembly 2 mounted on the vibrofocus holder at the exit of the die.

The disadvantage of this device is its low productivity, due to the fact that the device contains only one deforming unit, as well as the fact that the wedge clamp installed in front of the HAIL is passive during metal processing and the rate of metal deformation is determined by the rate of oscillation .

The closest to the proposed technical essence and the achieved result is a device for deforming a metal using oscillations, containing a hollow frame with ends in the form of flat membranes, on which a wedge clamp and a die are fixed coaxially and sequentially along the lug, source of working medium supply pulse, connected to the hollow body 3.

The drawback of the device is its low productivity due to the fact that the device contains only one deforming unit.

The purpose of this method is to increase device performance.

The goal is achieved by the fact that a device for deforming a metal using vibrational oscillations, comprising a hollow body with flat membrane ends on which a wedge clip and a die are fixed coaxially and sequentially in the course of drawing, the source of pulsed working medium supply, connected to the hollow body, is provided with additional a wedge clamp and a wave one, with the additional portage attached to the first membrane along the wedge clamp, and the additional wedge clamp attached to another membrane e behind the trail.

The drawing shows the proposed device, the cut.

The device contains a vibration exciter comprising a hollow body 1 with ends made in the form of flat membranes 2 and 3. In the first along the metal drawing 4

The membrane 2 is mounted with a self-braking clamp 5, behind which a portage 6 is installed. The spring 7 serves to initially press the jaws 8 of the clamp 5 to the metal 4.

On the second membrane 3, a second portage 9 is installed, behind which a wedge clamp 10 is placed. To press the jaws 11 of the clamp 10 to the metal 4, a spring 12 is provided. The hollow body 1 is filled with the working medium 13 and is connected to its pulse supply source (not shown) through

hole 14.

The device works as follows.

Metal 4 with a pre-pointed end is introduced into the device and a pulsating pressure fluid is supplied to the exciter (the direction of fluid flow is indicated by an arrow). Under the action of each pressure pulse, the membranes 2 and 3 bend outward. In this case, the first along the portage 6 gets movement

towards the metal 4, the front end of which is clamped by a clip 10 moving along the metal. Thus, metal 4 is drawn through the first filament 6 during the rise of the pressure pulse.

a length equal to the sum of movements during this time of the dies 6 and clamp 10. During the period of increase in pressure in the exciter, the second ditch 9 moves along the metal 4 and does not deform it.

During the decay of the fluid pressure, the membranes 2 and 3 return to their original position. At this time, the wire 9 moves towards the metal 4, the rear end of which is clamped by the clip 5 moving along the metal. During the decay of the pressure pulse, the metal 4 is pushed through the fiber 9 by a length equal to the sum of movements during this time of the dies 10 and clamp 5.

With a new pressure pulse, the cycle repeats.

Since the deformation of the metal of the first HAIR 6 takes place only during the buildup of the pressure pulse in the vibration exciter, and the die 9 deforms the metal

only during the fall in pressure, the loading of the said fibers occurs alternately. This makes it possible to double the deformation of the metal in a single pass through the device and to increase the productivity of the device approximately by half.
