Technical Information SITEMA - PowerStroke Locking, actuating and releasing by pneumatic pressure TI-P12-EN-07/2012 English translation of German original SITEMA - PowerStroke Mould Closing Device Type FSKP • There is a detailed description of the control and use of the SITEMA - PowerStroke type FSKP in the „Assembly Instruction MA-P12“. pLong working Purpose The mould closing device SITEMA - PowerStroke type FSKP is a clamping unit with a a strong integrated short stroke cylinder. For this device, only pneumatic and no hydraulic is necessary. Application examples The SITEMA - PowerStroke shows its strength, if short strokes with high force (PowerStroke) and long strokes with small forces (working stroke) are required in the same application, and no hydraulic is available or desired. The SITEMA - PowerStroke is further not limited to the end position of the drive only, but can be used within the full stroke of the drive. The unit can be mounted on a standard cylinder or on a separate rod. So the unit can be used for the following applications: • • • • • • • • • • mould closing die cutting stamping riveting bending metal forming compression moulding crushing jointing fixation pShort PowerStroke Application example with SITEMA - PowerStroke mounted on a standard pneumatic-cylinder SITEMA GmbH & Co.KG .

Technical Information SITEMA - PowerStroke Locking, actuating and releasing by pneumatic pressure TI-P12-EN-07/2012 If the port L is switched to pressure-free after insertion of the rod, then the unit is ready for the closing stroke. The proximity switch 2 is no longer energised. 1.4 Executing the closing stroke closing direction closing force Design of the SITEMA - PowerStroke (clamping released) closing direction executed closing stroke The clamping system of the SITEMA - PowerStroke consists of the clamping jaws (X) Abb. 1 and the clamping sleeve (Y) Abb. 1 which are braced against each...

Technical Information SITEMA - PowerStroke Locking, actuating and releasing by pneumatic pressure TI-P12-EN-07/2012 2 Important installation prerequisites 2.1 Rod requirements The function of the SITEMA - PowerStroke is only guaranteed for proper rod surfaces: Requirements for rod: • The rod end is fitted with a lead-in chamfer (min. 3x20°, rounded) as a mounting aid. • The rod surface is hardened (at least HRC 52), polished and is within the ISO tolerance field f7. In the operating range of the SITEMA - PowerStroke it demonstrates a roughness depth of Rz= 1 to 4 µm. Optimal conditions...

Technical Information SITEMA - PowerStroke Locking, actuating and releasing by pneumatic pressure TI-P12-EN-07/2012 2.4 Monitoring by proximity switches Proximity switch 2 "clamping released" indicates, that the rod is not locked by the SITEMA - PowerStroke. So if this signal is active, the rod/tool can be moved by the standard drive. Proximity switch 3 "stroke limit reached" shows, that the whole powerstroke was performed by the unit and that the internal stop of the SITEMA - PowerStroke is reached. In this situation, the closing force is no longer fully active. So this signal 3 normally...
