Propellant magazine for a propellant-operated setting tool and a propellant-operated setting tool

A setting tool for driving in fastening elements includes a drive piston () displaceable in a piston guide () between its initial () and setting positions, and device for returning the drive piston () in its initial position upon completion of a setting process and having an electromotive drive () and a transmission () for transmitting a motive actuating torque to the drive piston ().

Setting tool

A propellant charge-operating setting tool for driving fastening elements and including a housing ( ), a setting mechanism ( ) located in the housing ( ) and actuated in response to ignition of a propellant charge ( ) for driving in a fastening element, and a device ( ) for cutting a used portion of a propellant charge-carrying magazine strip ( ).

A holder for a drive piston ( ) of a setting tool, and including a return element ( ) having a first end ( ) that applies pressure to the drive piston ( ), and a second end ( ) spaced from the first end ( ), and axial and radial stop elements ( ) fixedly securable in the setting tool and against which the second end ( ) of the return element ( ) is displaceable and elastically deformed upon displacement of the drive piston ( ) in the setting direction ( ).

Holder for a drive piston of a setting tool

A cartridge for setting devices if formed of a pot-shaped plastics material cartridge housing ( ), which has a surface ( ) contacting the inner contour ( ) of a cartridge chamber of the setting device. A sealing cover ( ) closes off the housing ( ) at its open end ( ). The sealing cover ( ) has a cylindrical section ( ), which extends into the interior ( ) of the housing ( ) and expands under the pressure developed upon ignition of the cartridge, so that a positive connection results between the housing ( ) and the sealing cover ( ).

Cartridge for setting devices

A piston holder for a drive piston of a setting tool and including at least one clamp member ( ) that is constantly non-rigidly pressed against a circumference of the drive piston ( ), and elements for supporting the at least one clamp member for an eccentric movement in a plane in which a central axis ( ) of the drive piston ( ) is located.

A piston holder for a drive piston ( ) of a setting tool and including a circumferential groove ( ) provided in a stationary, with respect to the setting tool, component of the setting tool and surrounding the drive piston ( ), with the circumferential groove ( ) becoming shallower in a drive-out direction of the drive piston ( ), and an O-shaped helical tension spring ( ) located in the circumferential groove ( ) and concentrically surrounding the drive piston ( ).

A cartridge magazine for explosive powder charge-operated setting tools including a charge-receiving member ( ) having a plurality of spaced from each other, charge-receiving chambers ( ) for receiving propellant charges ( ), respectively, and a bottom ( ) for closing the charge-receiving chambers ( ) and formed of a heat-releasing, fusible and current-conducting foil.

Cartridge magazine
