Abstract

This invention relates to multipliers for a hydrostat. The aim of the invention is to increase productivity and reduce energy costs. The multiplier consists of a vessel 16 and a plunger 14 with a flange 15 and a housing 2 placed therein. The housing 2 and the plunger 14 are installed to form cavities 17-19. When the multiplier operates, a high pressure is created in the cavity 17 in one stroke of the plunger 14, which makes it possible to increase the speed of the high pressure injection and to increase the productivity of the pressing process. A multiplier requires one pump to operate, which reduces energy costs. 1 il.

This invention relates to powder metaturgy, in particular, to devices; hydrostatic treatment of powder materials.

The chain of the invention is to increase productivity and reduce energy costs.

The drawing shows a multiplier; in the upper part, the position at the moment of creating the maximum pressure in the working network of the hydrostat; at the lower part, at the moment of creating the pressure in the case of the multiplier.

The multiplier consists of a working chamber 1 associated with a multiplier consisting of a body 2j on the side surface of which holes 3 are made and having a flange 4 with sealing elements and a flange 5 with sealing elements and holes 6 in which large steps 7 of rods are located . Less; e steps 8 rods are placed in holes 9 of bushings 10 with limiters 25 11. At the end of a smaller stage 8 rods, washers 12 are fixed, and at a larger step 7, sealing elements are placed in holes 6, In an opening 15956284

placed to the right, the rod washer 12 moves the sleeve 10, and the stops 11 close the separator plungers 13 in the holes 3. The sealing 17 of the cavity 17 is accomplished by sealing the flanges 4 and 5 through the vessel 16 and through the hole 6 by sealing elements of the large steps 7 of the rods. After that, the adjustable valve 20 is actuated and the pressure from the cavity 17 is transferred to the cavity 19, acting on the flange 15, which, moving to the left, reduces the cavity 18 and creates a working pressure in the working chamber .1 in one stroke of the axial plunger 14.

The multiplier requires one pump unit, which drives all the pistons and the plunger, which reduces energy costs.

The device uses not only oils, on which standard pumping units operate, but also other non-viscous liquids, such as water.

The use of the proposed device allows to increase productivity and reduce energy costs.

13, and in the housing 2 an axial plush 14 is placed with a flange 15 on which the rods are fastened by large steps 7. The multiplier is enclosed in a vessel 16 with the formation of cavities 17-19. The cavity 1 7 between the housing 2 and the vessel 16 is connected to the cavity 19 between the flange 15 and the walls of the vessel 16 through the adjustable valve 20 and is connected to the source 21 of the fluid supply.

The device works as follows.

In the working chamber 1 is placed a mold with a powder (not shown). Fluid is pumped into the multiplier body 2 from the main pipeline under pressure, with the result that the axial plunger 14 with the flange 15 moves to the right. Simultaneously, the separator plungers 13 move in the direction from the axis, and the stem stage 8 moves in the hole 9, without moving the sleeve 10. After this, the fluid supply source 21 pumps oil into the cavity 17, the separator plungers 13 shift to the axis, creating pressure in the multiplier, at the same time, the plunger 14 additionally provides fluid transfusion and low pressing.
