B18500_swing_clamp_Low_pressure
This unique series of Swing Clamps provides considerable clamping force at lower hydraulic pressures, allowing direct connection to the low-pressure hydraulic system of a machine tool. These are extremely compact, heavy-duty clamps with a reinforced swing mechanism and a heavier clamping arm to exert high clamping force in relation to clamp size. Swing Clamps utilize a sturdy helical-cam mechanism to swing the clamping arm clear for unrestricted loading. Arm can be mounted to start its 90° swing from any position within 360°. The top-flange version shown here allows low-profile mounting, using either standard fittings or manifold mounting.
Available in four clamp sizes, double-acting only, with a choice of clockwise, counterclockwise, or zero° swing. Available with 45° and 60° swing angles by special order. Clamping force at 1000 psi with a Standard Clamping Arm:
            450 lbs     (3 series)
            850 lbs     (4 series)
          1870 lbs     (6 series)
          2990 lbs     (7 series)

Clamping Action 

Swing Clamps are pull-type cylinders where part of the total stroke is used to swing the piston, and the remaining stroke is available as the clamping range. Applying fluid pressure to the A (clamping) port swings arm 90° over workpiece then clamps down. Switching pressure to the B (unclamping) port positively lifts arm then swings it back 90° for loading/unloading.

 

Reinforced Swing Mechanism 

Reinforced swing mechanism ensures positive arm position. The safety-clutch mechanism normally incorporated into our swing clamps is omitted in this design. In case the workpiece hits the clamping arm during loading, the angular position of the swing-clamp arm will be exactly maintained. Using a longer, heavier clamping arm will also not declutch the swing arm and affect arm position.

 

Mounting and Fluid Supply 

 

    standard fittings                             manifold mountings

Dual mounting capability allows any clamp to be mounted using standard fittings or manifold mounting. Two 1/4″ BSPP ports. For optional manifold mounting, use the O-ring ports underneath, instead of the standard ports. Do not use NPT fittings. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing. Fasten clamp with four socket-head cap screws.

 

Clamping Arms 

Order clamping arm separately – see clamping accessories.  The maximum allowable operating pressure is 5000 psi. Longer, custom clamping arms will reduce allowable operating pressure, inversely proportional to arm length. Optionally, the clamping arm can be positively keyed to the piston rod in a fixed 90° position by inserting an indexing pin (order separately).
