Abstract

The invention relates to the processing of metals by pressure and can be used in devices for stamping sheet blanks by an elastic medium. The purpose of the invention is to expand the technological possibilities of punching with an elastic medium by controlling the magnitude of the deforming force by changing the flow rate of the fluid. The press contains an injection line 1 consisting of a cylindrical section for accelerating fluid flow 2 and a conical diffuser 3, a working chamber (RK) 4, a discharge line 5, a diaphragm (D) 6, a table (C) 7. Mounted on a C 7 rig, the workpiece is pressed to D 6 and is fixed in this position. The creation of hydrostatic pressure on D 6 is carried out by converting the kinetic energy of the fluid moving along the injection line 1 at a given speed into the potential in the RK 4. The formation of the preform is formed. After that, the fluid in RC 4 is decelerated by stopping its injection by pump 8, the pressure in RC 4 is relieved, C 7 is retracted. 1 tab., 3 Il.

Description

Next, the values of LP are determined depending on the velocity at the entrance to the diffuser at the indicated values of Kip.

According to the results of calculations, a graph is plotted.

A positive effect in the application of the proposed press is due to the possibility of differential prescription for forming and calibration depending on the type of part and material, which saves energy and by reducing the time for changeover press, leading to a reduction in the complexity of manufacturing the part.
