100-2 Manual coupling systems for manual operation, single-acting or double-acting, pmax = 500 bar

Manual coupling systems are used for machine tools that work with hydraulic devices but are not equipped as standard with a hydraulic interface for supplying pressurized oil to the fixture pallet. Coupling and uncoupling is carried out by the operating personnel.

In contrast to quick-release couplings, there is no risk of confusion between the pressure line and tank line with manual couplings. The coupling process is also faster. By using a hydraulically releasable non-return valve, the coupling can be easily disconnected after the clamping process has been completed without the need for force and the system pressure is maintained. To release the pressure, the T-connection is pressurized. In the single-acting version, the ball valve performs this function.

The necessary safety elements are already installed. These are a hydraulic accumulator, a non-return valve and a pressure relief valve that protects the hydraulic accumulator from a pressure increase of more than 10%. The coupling nipple unit can be equipped with two different hydraulic accumulators. HYDROKOMP recommends the hydraulic accumulator with a nominal volume of 13 cm³ up to an oil volume in the device of approx. 100 cm³. If the required oil volume is greater, the hydraulic accumulator with a nominal volume of 40 cm³ should be used. The coupling systems are equipped with G1/4 threaded connections and O-ring flange connections as standard. There are O-ring countersinks in the flange surface at the bottom and rear, which also allow the pressure oil to be supplied without a line via drilled channels.

The coupling mechanism unit is used to lock both assemblies for pressure transmission. The two tie rods are inserted into the bayonet catch. The levers are then turned sideways by 90°. The tie rods are shortened via the two integrated molded bevels and the coupling process is carried out. The locking stroke is 5 mm.

Safety holder with inductive proximity switch and plug for holding the coupling mechanism strip in a parking station when decoupled. The safety holder can be connected directly to the machine control system via the integrated proximity switch. This means that pallets can only be transported when uncoupled.
