SU72529A1 - Method of pressing and stamping metal products - Google Patents

Description

The invention reduces the effort required for the deformation of the metal by assisting accessions to the shyuosam, which provides for npejHBHOOTb pressure.

The prerequisite method means that during the normal approach of a tool and a product, the pressure between them will be repeatedly npijHBaxa.

Adaptation to presses for carrying out the method is characterized in that its slider or table, or both, is provided with a hydraulic influence by a pneumatic cushion communicated with a pressure source through a shut-off valve that is multi-sided and closed during time (sh: working stroke of the press.

The workpiece indra, filled with liquid, is connected to the reservoir by tubes. In the reservoir, the fluid is under the pressure of the wah piston. A stop valve rotating valve in one of the tubes, as well as a second stop valve in the other tube of the synchronic valve with a press. When the press is turned on (working stroke), the rotating crane automatically turns on and starts to spin at the speed of rotation. At the same time, when the press starts to work, the first shut-off valve opens automatically, and the liquid in the cylinder begins to flow into the tank 2 through the pressure of the valve at the pressure of the press. At the moment of connecting the first pipe to the reservoir through the hole of the rotating tap, part of the liquid from the cylinder under the action of the pressure of the press flows into the reserve fire, and the sample together with the slider

is lowered by a magnitude. rotating will overlap ne | W7U, the sample is amended. Since the motion of the slider is continuous, some movement of the sample occurs. This way, the world is going through the gap.

When the sample has been crimped and the slider is pushed up, the first shut-off valve will automatically close, and the second stop valve will open, and the liquid from the reserve tank will, under the pressure of the weight of the piston, flow into the working cylinder and send it to the original odozhivie.
