Hydraulic and pneumatic components

The hydraulically-operated bore clamp is particularly suitable for clamping in workpieces with smooth bore holes in the support surface ranging from 8 to 12 mm in diameter. The workpiece is put directly onto the hardened surface of the bore clamp and will not be deformed during clamping. Since clamping is effected within the bore, the remaining surfaces are free for machining on 5 sides.

- axial clamping in simple smooth bore holes
- compact eccentric design for limited space
- different support heights
- hardened support height
- easy exchange of clamping bushings and tie bolt
- 3 pneumatic monitoring functions can be connected
- separate connection for positive air pressure protection
- integrated bleeding screws

Application
For the operation of hydraulic clamping fixtures and other handling and clamping systems on machine tools.

The power units of this series consist of individual modules that are selected depending on the application and are assembled on the basis
of a type code to a power unit ready for use.

- Power unit (reservoir, pump, motor)
- Connecting block basic functions
- Valve block with up to 4 control circuits
- Electronics

- for single and double acting cylinders
- continuously adjustable operating pressure
- expandable to up to 8 pressure circuits
- constant flow rate
- wide range of valves
- wide range of hydraulic functions
- energy-saving mode S3 (intermittent mode) or S6 (unpressurised cycle)
- supplied ready for connection

Pneumatic swing clamps with locking mechanism maintain clamping force
- in the event of a pressure drop in the pneumatic line;
- if the supply line of a pneumatic clamping device has to be uncoupled in the clamped state, e.g. for clamping pallets.

Adjustable swivel speed
robust swivel mechanism
automatic locking in the clamping range
No loss of clamping force during uncoupling

Pneumatic swing clamps are used for applications which require only low clamping forces. The installed magnetic piston allows monitoring of clamping and unclamping position.

When pressurising the element, the clamping arm swings and lowers by 90° to the clamping position and then lowers to the clamping point. The position monitoring gives the required information regarding the position of the piston, but not regarding the position of the clamping arm. Monitoring is made by electronic sensors which detect the magnetic field of the magnetic piston. The switching points can be continuously adjusted by displacement of the magnetic sensors.
