On vtedena at vadena scheme of the node nressopani.

The press unit of the machine under the design. The I6M consists of a cylinder L of coaxial with multiplier 2, a controlled check valve 3, a pressure source-g, a 1-unit control sensor 5, a pressure sensor 6, an adjustable valve 7, an adjustable separator 8, a dispenser 8, hydraulic hydraulic Yakkumul 9, adjustable retaining valve 10, adjustable throttle //, universal valve 12, check valves 13 and 14, program module 15.

The pressing unit works as follows. In the initial position (at the end of the transducer: out of the two phases of the pressing — overlapping the filler skull and the filled form), the separator 16 of the adjustable separator of the dispenser 8 is in the extreme position when the working volume of the last extrusion into the rod cavity of the multiplier 2 is pneumatic-hydraulic accumulator The torus 9 is closed (its internal cavity is iodized by the pressure of the precharge), the separator II (for example, the heater) tightly closes the inlet, there is no working fluid in the accumulator, there is no outlet pressure.

Shto1K Ova cylinder space compression / is connected to the word piston iolosti cylinder compression / n multiplier 2 is under davleiiem pressure 4 source rod cavity multiplier 2 locked controllable valve 7 is controlled by klaiai 12, steering booster valve 10 is set to pressure obeopechivayushee necessary intermediate pressure multiplication.

Software device 15 for sig: 1am pressure sensor 6 and track contrat sensor 5 provides the necessary techiological: shutter speed before starting the operation of the multiplier and gives the command to open the set-up valve 7 located at the outlet of the rod cavity of the multiplier 2. The working fluid from the rod the multiplier through the open controlled valve 7 enters the line 18, on the lotor there are the following taps: to the adjustable separator-dispenser 8, the integral guide) and the original battery I have an adjustable podium th klaian 10, check valves 13 -A 14.

An adjustable separator dispenser 8, the output of which is connected through the rod cavity of the press cylinder / with a drain, can accept the working fluid practically without backwater. The battery 9 is sealed with a pressure with a charging pre-charge and can accept the working fluid only if its

pressure will exceed the precharge pressure. Adjustable retaining valve 10 passes the working fluid only when its pressure exceeds the pressure or its settings. The check valve 13 does not allow the working fluid to pass, since its output is blocked through an adjustable throttle // controlled valve 12. The check valve 14 does not allow the working fluid to flow away from

the rod cavity of the multiplier 2. Thus, at the first moment, the working fluid from the rod stock of the multiplier 2 is displaced into the regulating separator-dispenser 8 without backwater. At the same time, the rod of the multiplier 2 is rapidly accelerated, and the pressure of the multiplication in the piston cavity of the pressing cylinder rises sharply due to the compression of the working fluid in it. As soon as the separator 16 of the separator-dispenser 8 comes to its extreme position, the pressure in the line 18 increases and exceeds the charge 1g of the preliminary charge of the battery 9 and opens it. The working fluid from the rod end of the multiplier 2 is displaced into

accumulator 9, the pressure in the latter grows, i.e. the counter pressure of the multiplier and the stockpile pressure increases. Protometer SMie s rod0: the cavity of multiplier 2 rises to the set pressure of adjustable valve support valve 10 and is maintained last and for a limited time within the cycle.

With a tail block protector: With the help of the multiplier 2 it continues its course up to the steady-state ground pressure.

multiilation The magnitude of this pressure and the set time are provided by adjusting the stroke of the splitter 16 of the adjustable splitter-dispenser 8, pre-pressurized pressure (5 hours) and the setting of the adjustable retaining valve 10. This pressure can be maintained in the system for an unlimited time in the pickle line.

After the required delay time sufficient for the formation of a box on the ebb, the software / 5 program opens the control valve 12 at the outlet of the adjustable throttle, connecting the line 18 through the rod cavity of the pressing / draining cylinder. The working fluid from the battery 9 at a speed determined by the setting of the adjustable throttle 11 is supplied to the drain, the pressure in the battery 9 decreases and at the same time the counterpressure in the rod cavity of the multiplier 2 drops. And the backpressure decreases with the NOW speed to the preload pressure of the battery I and then rez: ko to nil. The established paiBHOBecne forces on the multiilicato stem. A 2 is broken, the stem begins to move,

Continuing to compress the working fluid in the piston cavity of the pressing cylinder 1, the multiplication pressure increases to the steady-state upper limit value. SOURCE.-1IT completes the casting.
