B. CYLINDER SWING SPEED CONTROL Flow control valve for the clamping process. All standard cylinders are prepared for retrofitting the flow control valve (accessory delivered upon request). C. CYLINDER OPENING CONTROL FOR ROBOTIZED UNLOADING 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.

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,...

INSTALLATION INSTRUCTIONS FOR LINK CLAMP CYLINDERS CG SERIES CORRECT CLAMP ARM INSTALLATION 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. L 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...

If the workpiece needs to be clamped on an inclined If the cylinder is installed at a different angle, the surface, the cylinder must be installed at right angles clamping forces would produce reaction forces that to the surface. could damage the cylinder. 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.

CG LINK CLAMP CYLINDERS 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: 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. If the clamp arm dimensions are known, the maximum operating pressure is determined on the basis of the following formula: With...

In this case, the following formulas must be used: Fm = Spring force [kN] k, l = Clamping arm dimensions [mm] p = Pressure [bar] S = Clamping area [cm2] 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 l at which the R limit value is reached. The cylinder-specific clamping force for different clamping arm lengths can be represented in a graph.
