SITEMA PowerStroke FSKP Locking, actuating and releasing by pneumatic pressure English translation of German original Technical Information TI-P12 SITEMA PowerStroke Mould Closing Devices series FSKP 0 drive system for powerful forces on a short stroke 0 pneumatic actuation 0 closing force up to 3 tonnes Technical Information SiTEMA ■ Expertise in Safety A detailed description regarding control and use of the SITEMA PowerStroke is given in the “"Assembly Instructions MA-P12”. 1 Function The Mould Closing Device SITEMA PowerStroke series FSKP clamps and actuates a rod in one direction (closing direction). A force proportional to the operating pressure is exerted to the rod by friction. Only a pneumatic system (and no hydraulic system) is needed for the use of this series. 2 Applications The SITEMA PowerStroke series FSKP with its integrated short stroke cylinder is typically used in: • mould closing • die cutting • stamping • riveting • bending • metal forming • compression moulding • crushing • jointing • fixation The series FSKP is available in 2 styles: • S types: for use with separate clamping rod • Z types: for use with standard pneumatic cylinder according to ISO 15552 1. The clamping is released; the rod is free. 2. The cylinder executes the working stroke. Then, the PowerStroke clamps the rod. 3. The PowerStroke executes the closing stroke. SITEMA GmbH & Co. KG .

Technical Information SITEMA PowerStroke FSKP Locking, actuating and releasing by pneumatic pressure TI-P12-EN-02/2016 closing direction The following function description specifies the typical case if the SITEMA PowerStroke is mounted to the stationary machine element. Then, the rod is moving. The closing direction is shown as it would appear in this case. Alternatively, it is also possible to mount the SITEMA PowerStroke to the moving machine element. Then, the rod acts as a connection to the stationary machine element. In this case, the closing direction is reversed closing direction...

If the complete closing stroke is executed, proximity switch 3 will signal “stroke limit reached”. During normal operation, this signal should never be active (see Chapter 4.4 “Monitoring by proximity switches”). With the help of this signal, the correct function of the unit can be constantly controlled. To release the clamping, pneumatic pressure at port K must be switched off and pressure must be applied to the port L. As a result, the rod first moves back a little bit (previously-executed closing stroke) and then the clamping gets released. 4 Installation prerequisites 4.1 Styles The...

Notes 1. The rod may not leave the clamping unit during operation. However, special designs which allow the rod to be removed and inserted with each stroke are possible. In this case, the rod may only be inserted in the released state (proximity switch signal 2 active) through the centre ring. Before the rod may be clamped, it has to be ensured, that the rod is inserted to at least the “minimum insertion depth” indicated in the special design's specifications. 2. During the release process force on the rod is not allowed. This has to be considered in the control of the primary drive. 3. In...
