SU142502A1 - The method of obtaining deforming efforts - Google Patents

Description

Methods are known for producing shock deforming forces by means of electro-hydraulic shocks reproducible in a fluid medium.

For carrying out forging, stamping, flaring, embossing, work hardening, cleaning, blocking, bending, breaking, cutting and other types of material processing, the shock deforming forces of the proposed method are obtained by electro-hydraulic shocks reproduced in a piston filled with a liquid cylinder or chamber with a membrane force of blows and transmitting them directly or through the corresponding instrument connected with them to a deformable object, and the return movement of the piston or membrane is carried out Thu atmospheric pressure in the collapse of the cavitation cavities.

Electro-hydraulic shocks are reproduced in a known manner: as a result of pulsed discharges at the electrodes within the volume of any go-conducting or non-conducting liquid.

Adjusting the force or stiffness of impacts is carried out by changing the parameters of the pulses at a given spark length or the distance of the electrodes from the ground or membrane, which changes the physical properties of the fluid, such as its elasticity.

In order to replenish the loss of the working fluid or to continuously replace it with simultaneous removal of traces of the formed gas or vapor, the fluid inlet or outlet channels are cranked.

FIG. shows a device for carrying out the proposed method; in fig. 2 - the mechanism of the wedge stop.

In the guides 1 of the bed 2, the cylinder 3 freely moves under the action of its own weight, with the piston 4, which lies on the machined No. 142502-2 I MOM of the product 5. Raising and lowering the cylinder with the piston on the product

carried out by conventional means - manual or mechanical.

In the cylinder, a working cavity 6 is created filled with liquid. SKBERZ.TINKES of the cylinder into the working cavity are entered electrodes 7. By the cranked bore 8 of the working cavity is connected to the reservoir I in the capacitor and liquid, which is poured into the reservoir through the funnel 10. -

In order to eliminate reactive energy losses during shocks, a wedge-mounted device mounted above the device body was made in the form of a wedge mechanism consisting of two flat wedges I and 12, the movement of which is controlled by hydraulic cylinders 13 and 14 embedded in the frame. As the product deforms, the wedges automatically shift, creating a constant stop.

The described method can be used in the plant-building industry and other fields of technology.
