A setting tool includes a sleeve-shaped housing (), a piston guide () and an ignition unit () located in the housing (), with the ignition unit () having a cartridge chamber bottom () for enclosing a propellant () in cartridge chamber (), which is located between the piston guide () and the ignition unit () and a locking device () having a locking position () in which the ignition unit () is held in a pre-loaded position () against an energy accumulator () and in which the cartridge chamber () remains open, and having a release position () in which the ignition unit () is displaced to its ignition position () by the energy accumulator in which the cartridge chamber bottom () closes the cartridge chamber ().

Setting tool

An explosive powder charge operated setting tool includes a housing (1), a handle (2) located on the housing, a piston guide (4) and a firing pin guide (8) each located within and being axially displaceable relative to the housing against the force of a damping device (17) bearing against a trailing end stop face within the housing directed in the driving direction. The housing (1) forms an axially extended receiving space (24) for guiding the piston guide (4). The receiving space has an axial length (LA) between a leading end face of the housing and a leading end face of the firing pin guide in a first position. The piston guide (4) has an axial length (LK) coinciding at the most with the axial length (LA) of the receiving space.

Fastening element setting tool with shock damper

An explosive powder charge operated setting tool including a housing(1), a stud guide(3) projecting beyond the housing(1) in a setting direction and axially displaceable relative to the housing(1), a guide channel(4) extending substantially transverse to a longitudinal extent of the stud guide(3) for receiving a spring-biased, strip-shaped magazine for fastening elements and having side recesses, and a pivotal lever(8) provided on the stud guide(3) and cooperating with the housing(1), the lever(8) being pivotable into a blocking position, in which the lever(8) projects into a clearance cross-sectional surface of the guide channel(4) upon displacement of the stud guide(3) toward the housing(1).

Explosive powder charge operating setting tool

An explosive powder charge operated setting tool includes a housing (1), a piston guide (13) for a driving piston (9) located in the housing. The driving piston (9) can be propelled from an initial rearward position through a bore (18) in the piston guide (13) into a forward driving position by gases generated from an ignited cartridge charge (12) in a cartridge chamber (10) located rearwardly of the initial rearward position of the driving piston. A channel (18a, 18b) is located in the housing in flow communication with the cartridge chamber and communicating with the guide bore (8) in the piston guide (13). A check valve (5) is positioned in the channel (18a, 18b) and forms a storage space closed to the ambient atmosphere and made up of a section (18a) of the channel (18a, 18b) closer to the forward driving position of the driving piston and of the guide bore (8). The check valve (5) can be closed by the gas in the storage space.

Explosive powder charge operated setting tool

An explosive powder charge operated setting tool drives fastening elements, such as bolts, nails, and the like into hard receiving materials. The setting tool has a housing (1) with a piston guide (2) including a cartridge chamber (6) axially displaceable in the housing. A driving piston (4) is axially displaceable in a guide bore (5) in the piston guide. A firing pin guide (3) is located in the housing rearwardly of the piston guide and is displaceable parallel to the driving direction of the tool. An inertia mass (12) cooperates with a control member (17) for regulating the power output of the tool.
