HYDRAULIC INTENSIFIER WITH URM-FL FILLING SYSTEM


When the “P” port is pressurized with low pressure, the high pressure is available at “A” outlet port by the pilot check valve “X”. When the oil circuit has been filled, the pressure automatically increases: as soon as the pressure set at the sequence valve “S” is exceeded, the hydraulic intensifier works and increases the hydraulic pressure at “A” port. The sequence valve “S” have to

: Outlet port - high pressure (secondary circuit)

: Inlet port - low pressure (primary circuit)

: Control (opening) of the pilot-operated check valve

: G1/4” port for pressure controller or manometer for pressure monitoring

be setted with pressure valve between 80-90% of the low inlet pressure. The URM450-FL2 and URM450-FL3 hydraulic intensifiers are equipped with an integrated pilot check valve that ensures a fast flow unloading of the high pressure and minimizes any counterpressure caused by inside check valves in line.

MULTI-PASSAGE ROTARY JOINTS WITHOUT LEAKAGE RECIRCULATION

ROTARY JOINT APPLICATION (EXAMPLE)

GV series

Turntable

Fixed table

Axis

of

rota

tio

n

GV series multiple-passage rotary joints are designed to supply rotating or swinging fixtures (work-holders) with pressurized oil. These rotary joints can be coupled when pressurized and must be installed in the centre of rotation. A low torque is required for starting the rotating movement. GV multi-passage rotary joints do not require leakage lines as no internal oil leakage occurs.

To ensure a long service life of the internal seals, make sure to connect the rotary joint to all hydraulic supply ports. The operating temperature should not exceed 60°C. In addition, we recommend using oil filters with a 10 micron filter mesh.

GV rotary joints are made of heat-treated and ground high-quality steel. They are only suited for operation with hydraulic fluids, cooling lubricants must not be used.

Application example:1) Cylinder no. 1 pushes the workpiece against the

“D” stop.2) The pressure increases up to XX bar and

opens the sequence valve.3) Cylinders no. 2 and no. 3 push the workpiece

against the “B” and “C” stops.4) The pressure uniformly rises in all cylinders as

the sequence valve is completely open.

Sequence valves are used in hydraulic systems that require a pressure-specific priority or sequence of motions. A one-directional check valve is provided for the free return flow when operation is inverted. These extremely compact valves can be mounted either with the supplied O-Rings or in-line using the G1/4” BSPP ports directly on the clamping equipment.

Material:• Valve/cartridge body: Free machining steel,

blued.• Internal parts: High-grade steel, tempered and

ground.• Valve body surface: Zinc-plated

PRESSURE REDUCING VALVES

INSTALLATION DIMENSIONS

DIAGRAM

General instructionsThis valve is used to provide a reduced constant outlet pressure at the “A” port as compared to the higher inlet pressure at the “P” port. If pressure increases are likely to occur at the “A“ port, a pressure relief valve must be installed at this port. Mounting instructions:Before tightening the valve, unscrew the counter nut (AF=30 Z) completely. Tighten the valve body (AF=24 Y) with a torque of 70 Nm. Then tighten the counter nut (AF=30 Z) with a torque of 60 Nm. Proceed in reverse order for demounting.

MAX. OPERATING PRESSURE = 500BAR - VALVE ADJUSTMENT RANGE = 30÷380 BAR

ADJUSTMENT SEQUENCE

The pressure reducing valves of cartridge type VRP are designed as two way valves WITHOUT DRAINAGE. As soon as the set pressure is reached, the appropriate cone moves in closing position and with increasing pressure, stable closing is ensured as long as the pressure upstream from the valve is not released.

To adjust the set pressure, proceed as follows:1) Loosen the BR counter nut in order to ensure free

access to the R1 adjusting screw.

2) Pressurize the valve and check the set pressure downstream from the valve.

3) Release the pressure.4) Turn the R1 adjusting screw clockwise or

anticlockwise, i.e. turn it clockwise to reduce the set pressure and vice versa.

5) Pressurize the valve and check again the set pressure. Repeat the above steps until the desired pressure

value is reached and tighten the BR counter nut.

NOTE HYDROBLOCK checks all products to 100% before shipment. If requested during order placement, HYDROBLOCK will deliver the valve with the pressure being set to the specified value.

The CP30F pressure monitoring cylinder has been developed to check the clamping pressure in a remote fixture. As soon as the clamping pressure is reached, the external bolt is extended by 3 mm from the cylinder head and remains in this position as long as the operating pressure required for the fixture is maintained. If the clamping pressure decreases, the rod is retracted again into its initial position. Thanks to the easy adjustment of the operating pressure by an adjusting screw at the cylinder and the availability of different pressure ranges, the CG30P stands out for unparalleled versatility.

Application:When the fixture is separated from the hydraulic pressure generator, the use of a hydraulic accumulator is not always sufficient to keep the operating pressure at a level that ensures safe and reliable machining. Substantial oil leakage may reduce the clamping pressure exerted on the workpiece and cause serious damage to the equipment. By using the CP30F pressure monitoring cylinder, the operating pressure can be checked immediately before the machining process. If the required pressure level is not reached, the machining process is not enabled and the machine changes into emergency status.

Upon request, the valve protection cartridge is available for the entire swing clamp cylinder series.With the CPV01 valve protection cartridge the final user can perform clamping operations without any workpiece being mounted in the fixture for a functional check or for cleaning purposes. In this case, there is no risk of damage to the VCS clamp arm position control valve caused by excess stroke.

Installing the valve protection cartridge:The valve protection cartridge is factory-mounted to HYDROBLOCK cylinders when ordered as an option.However, retrofitting can also easily be carried out by the end user on the basis of corresponding mounting instructions. A simple M12x1 threaded seat is required on the clamp arm plate for mounting the valve protection cartridge for clamp position control valves.

ADJUSTMENT OF THE VALVE PROTECTION CARTRIDGE:To adjust the valve protection cartridge for clamp arm position control valves, proceed as described in the instructions 1 to 4 for the adjustment of the clamp arm position control valve. Use the 5 mm hexagon socket provided at the threaded cartridge end for this purpose. Upon completion of the adjustment, the pressure switch will indicate that the compressed air circuit is closed and enables the machine cycle start.The bolt of the valve protection can compensate an excess stroke of up to 10 mm and re-establish the starting conditions as soon as the cylinder has reached the unclamping position. Make sure that no stroke over 10 mm is performed during clamping operations without workpiece. We recommend mounting the swing clamp cylinders such as to ensure that the clamp arm in clamping position is close to the lower limit stop of the piston. In this case, the workpiece is properly and reliably clamped and perfect operation of the valve protection cartridge is guaranteed.

Using the unidirectional VRF18 flow control valve, the end user can set the swing speed of the clamp arm directly at the fixture and define the clamping sequence of the cylinders at the workpiece to be machined. This valve can exclusively be used for cylinders with flange connection and must be connected to the “A” clamping port. When the swing clamp cylinder is in unclamped state, the flow is free.

Note: To avoid damage to the internal seals, flow control valves MUST ONLY be adjusted when unpressurized. (see page 21)

The FIl14-10M is a modular filter of particularly compactdesign. The complex filtering system with two flowdirections is made of special steel; the nominal mesh sizeis 10 micron. The filter insert can be easily checked and replaced. The zinc-plated metal body is particularly suitable for installation in state-of-the-art machine tools and offersoptimum protection for hydraulic clamping systems,valves and pressure intensifiers. These filters are also indispensable for systems equipped with manual or automatic quick-action couplings, where a contamination of the hydraulic circuit by chips and metal particles can hardly be avoided during coupling and uncoupling.

Hydraulic accumulators are used in static clamping systems to compensate internal leakage or to minimize pressure variations caused by temperature changes.

AtteNtION:Hydraulic systems equipped with diaphragm accumulators must be provided with a pressure relief valve and a pressure gauge. In addition, a shut-off valve is to be provided for emptying the accumulator for maintenance or repair purposes. Before operating the accumulator, the minimum hydraulic pressure must exceed the gas pressure by at least 10%. Make sure not to exceed the specified maximum pressure values.

Note:Hydraulic accumulators cannot be used to compensate substantial external oil leakage. The cause of such leakage must be identified and eliminated.
