CLAMP ARM CLOSING/OPENING CONTROL SERIES CG

With link clamp cylinders equipped with a single integrated pneumatic supply channel, closing of the pneumatic line can only be ensured in the clamping and unclamping positions. The combined control of both hydraulic and pneumatic supply provides reliable monitoring of the clamp arm opening and closing positions, which gives maximum safety during robot-assisted unloading and perfect machining of the properly clamped workpiece. On the one hand, a combination of the pressure switch signal of the pneumatic supply line with the pressure switch signal of the hydraulic clamping line guarantees safe workpiece clamping and optimum machining conditions. On the other hand, combining the pressure switch signal of the pneumatic supply line with the pressure switch signal of the hydraulic unclamping line guarantees that the workpiece is unclamped and the cylinder is in open position, so that safe robot-assisted unloading of the machined workpiece is ensured. In ALL intermediate positions, NO WORKPIECE POSITIONING OR MACHINING is enabled. This solution simplifies the fixture circuit and eliminates the second pneumatic supply line: when designing and implementing the fixtures, certain machining steps can be omitted without affecting the safety of the line.

CLAMP ARM CLOSING/OPENING CONTROL SERIES CG

With link clamp cylinders equipped with the VCS clamp arm control valve (e.g. CG12.70 FDV), the opening position of the cylinder can be monitored, which gives maximum safety for robot-assisted workpiece loading/unloading. Considering the cylinder type used, clamping of the workpiece can be monitored by the pressure switch of the hydraulic clamping line. With CG link clamp cylinders from HYDROBLOCK, clamping is ALWAYS performed using the large cylinder area and there is no risk of

accidental opening of the pressurized cylinder. On the other hand, pneumatic control of the CYLINDER OPEN position is of FUNDAMENTAL importance, as the difference in the CG cylinder areas does NOT ENSURE complete opening of the cylinder, i.e. when leakage or oil is detected between the hydraulic lines. If necessary, a second pneumatic line will be provided upon request in order to monitor also the closed clamp arm position/clamped workpiece state.

INSTALLATION INSTRUCTIONSFOR LINK CLAMP CYLINDERS

CG SERIES

ATTENTION:For special application requirements, it is also possible to use the clamp arm in a laterally off-set position relative to the cylinder. In this case, the operating pressures specified in the diagrams MUST be reduced. Please contact HYDROBLOCK for more detailed information.

The clamp arm should be dimensioned such as to ensure that it is arranged at right angles to the clamping point. In addition, the arm must be aligned in parallel to the surface of the clamped workpiece, as otherwise the manufacturing tolerances would be affected by undesired stress.

Improper use of the cylinder may lead to irreversible damage to the equipment.

INSTALLATION INSTRUCTIONSFOR LINK CLAMP CYLINDERS

CG SERIES

Please observe the clamping arm lengths and the fields of application specified in the catalogue. Whereas extremely long clamping arms could affect

correct workpiece removal, very short clamping arms could lead to premature wear or damage to the cylinder.

If the workpiece needs to be clamped on an inclined surface, the cylinder must be installed at right angles to the surface.

If the cylinder is installed at a different angle, the clamping forces would produce reaction forces that could damage the cylinder.

CLAMPING FORCE CALCULATION

The clamping force is determined by the clamp arm length and the operating pressure. The F clamping force can thus be calculated using the following formulas:

C = [kN]p S

100

C [kN]F =k

l

k, l = Clamp arm dimensions [mm]

p = Pressure [bar]S = Clamping area [cm2]

= 0.9

As a function of the operating pressure, the clamp arm length l should be limited to a minimum value. This

length must not be exceeded to avoid damage to the cylinder.

p S -1

[mm]lmin =k

Rmax

100

If the clamp arm dimensions are known, the maximum operating pressure is determined on the basis of the following formula:

[mm]padm

=R

max 100

S (1 + )lk

With single-acting cylinders, the Fm spring force must be deducted from the force generated by the cylinder:


16703/2017

In this case, the following formulas must be used:

Fm = Spring force [kN]

k, l = Clamping arm dimensions [mm]

The constants to be used in the above formulas are specified in the table below:

The shorter the clamp arm, the longer the reaction time R. Depending on the pressure p, there is a minimum

length lmin

at which the Rmax

limit value is reached. The cylinder-specific clamping force for different clamping arm lengths can be represented in a graph.

Pneumatic supply: The special channel integrated into the link clamp cylinder is designed for the most different supply connections. Only a simple supply bore must be provided at any position of the fixture for this purpose. In particular with extreme complex fixtures or supports it is recommended defining the position of the pneumatic line in the planning phase.

Options:• The link clamp cylinder can also be ordered

without clamp arm (order no. CG8.250VN).

Pneumatic supply: The special channel integrated into the link clamp cylinder is designed for the most different supply connections. Only a simple supply bore must be provided at any position of the fixture for this purpose. In particular with extreme complex fixtures or supports it is recommended defining the position of the pneumatic line in the planning phase.

LINK CLAMP CYLINDERS WITH THREADED BODY

CGF SERIES

18903/2017

NOTE: Due to the large clamping surfaces and the substantial pressure losses in complex hydraulic circuits composed of numerous cylinders, it may take considerably longer time to unclamp single-acting cylinders or unclamping may not be possible at all. To ensure rapid and reliable operating cycles, we recommend using double-acting link clamp cylinders for this type of application.

Hydraulic link clamps are extremely compact clamping cylinders that generate high clamping forces at low supply pressures.

The special clamp arm motion facilitates workpiece loading and unloading and is particularly suited for operation in extremely restricted space conditions.

Link clamp cylinders are available in single and double-acting version (except for the CGF32.0 that comes as a single-acting cylinder only).

Thanks to the special profile of the cylinder body, it can also be supplied in a closed seat by means of the 1/8“-BSPP “A” port at the bottom.

In the single-acting version, the upper “B” port is provided with an incorporated sintered filter

designed to protect the cylinder chamber against the penetration of dust and chips.

We recommend connecting a vent pipe that leads into an area that is free from fluids.
