For any reason, do not reach into the pivoting range of the units, when they are in operation. Disconnect and lock out pneumatic and electric supply lines before operating on or around power pivots. Functional description PNEUMAX power pivots are rotating units typically used in the field of sheet metal working. A pneumatic cylinder operates a toggle linkage and drives it to its closed or open position. A toggle mechanism, integrated in the power pivot’s housings, guarantees the closed condition even in the absence of the actuation command. Power pivots installation to the tool Power pivots can be installed by one of their mounting surfaces, using dowels and screws according to its datasheet. The tightening torques to be set are: M5 5 N m / 3.68 lb·ft M6 10 N m / 7.37 lb·ft M8 25 N m / 18.43 lb·ft M10 35 N m / 25.81 lb·ft M12 50 N m / 36.87 lb·ft Use the key support surfaces, where available. Always use all the bores on the mounting pattern. Operating conditions Pressure operating range: from 2 to 8 bar/ from 30 to 115 psi Inline lubrication isn’t required: if lubricated air is used, it is necessary to continue using lubricated air, as the oil in it may have removed the basic lubrication in the device. Safety Power pivots are designed and manufactured as components to be incorporated in more complex systems or toolings: they are not stand-alone or independent ready-to-be-used devices and for this reason they are not equipped with their own safety equipment. Power pivots should not be operated before the complete safety control system of the tooling is activated and certified as conforming to all directives and related safety requirements. All operations and any maintenance work on power pivots must be carried out exclusively by trained staff and by observing all conditions which guarantee the safety of the personnel, in a complete standstill of the whole system. Handling Make sure that the packaging is not damaged before unboxing the units; given its considerable weight, it is advisable to use a suitable lifting system and to guarantee that during its handling the load is stably balanced. QIG_C_EN Rev.00 04.2022 An external actuating arm is connected to the shaft of the linkage. Power pivots are robust and reliable devices used in fixtures to accurately position and rotate workpieces: they are equipped with robust conical roller bearings with high-load capacity and side load acceptance. They can be mounted by their rear or front mounting surfaces and be used as dump devices, or they can be mounted by their side mounting surfaces and be used to rotate parts or assemblies. The open and closed positions of the actuating arm, also referred to as swivelling table or saddle arm, is detected by an inductive sensor through integrated sensor means in the linkage. Power pivots can be equipped with brake devices configured to stop the unit during its stroke in case of pressure loss. Automotive Catalogue PIVOTING
