Abstract
A device for producing an abrupt or sudden feed motion contains in a casing a feed device, which can be triggered by a trigger. The force necessary for advancing the feed device is applied by a spring, which is tensioned with the aid of a drive. The tool requires no cartridges for propellant charges.
Claims19
Device for producing an abrupt feed motion, having
- a casing (1),
- a feed device, which is movable between a retracted starting position and an advanced impact position, said feed device being connected to a piston and having an axial piston guide (7) for guiding the piston,
- a striker spring, which can move the feed device from the starting position into the impact position, and
- a drive for tensioning the striker spring, and
- a trigger for releasing the drive and the tensioned striker spring, said trigger comprising a displaceable tubular element (18) positioned coaxially to the piston guide (7) and moveable relative to the piston guide (7) for triggering the tensioned striker spring.

Device for producing an abrupt feed motion, having
- a casing (1),
- a feed device, which is movable between a retracted starting position and an advanced impact position,
- a striker spring, which can move the feed device out of a starting position and into the impact position,
- a drive for tensioning the striker spring, as well as with
- a trigger for releasing the tensioned striker spring, in which the feed device is connected to a piston (11), the device has an axial piston guide (7), wherein the drive has a dispensable tubular element (18) positioned coaxially to the piston guide (7) and which triggers the tensioned striker spring, and
- wherein the drive is constructed in such a way that following the advance of the feed device the drive further relaxes the setting spring to facilitate the sliding back thereof.
