摘要： A setting tool driving fastening elements, comprising a holder for a fastening element; a drive-in element transferring a fastening element in the holder into a substrate along a setting axis by a setting energy Ekin of at least 30 J and at most 600 J; a drive for driving the drive-in element toward the fastening element along the setting axis, the drive comprising a capacitor, a rotor on the drive-in element; and, an excitation coil, which during discharge of the capacitor is flowed through by current and generates a magnetic field accelerating the drive-in element toward the fastening element, the drive-in element having a piston diameter dK and a piston mass mK, and wherein, for dK, 2 3 ⁢ ( a + b ⁢ E k ⁢ i ⁢ n n ) ≤ d K ≤ 4 3 ⁢ ( a + b ⁢ E k ⁢ i ⁢ n n ) where a=33 mm, b=6 mmJ−n and n=⅓ and/or, for mK, 2 3 ⁢ ( c + d ⁢ E k ⁢ i ⁢ n n ) ≤ m K ≤ 5 3 ⁢ ( c + d ⁢ E k ⁢ i ⁢ n n ) where c=20 g, d=30 gJ−n and n=⅓.

摘要： A machine tool with a tool holder which is equipped to mount a tool, such as a chiseling tool, moveably along a movement axis. A striking mechanism contains a primary drive, arranged around the movement axis, containing at least one magnetic coil. The striking mechanism has a striker and an anvil arranged within the magnetic coil on the movement axis in sequence in the impact direction. The anvil protrudes at least partially into the magnetic coil. In addition, the striking mechanism can have an air spring affecting the striker in the impact direction. A controlled power source forms an electrical circuit in which a current flows, controlled at a target value, from the power source and into at the at least one magnetic coil during an acceleration phase. A controller ends the acceleration phase when a change, typical for an impact, is detected in the current flowing in the magnetic coil or a change, typical for an impact, is detected in a control variable of a control circuit of the power source.

摘要： The driving device 1, in accordance with the invention, has a ram 3, which, driven by compressed air, drives in the fastener 2. A pump device 5 produces the compressed air. The pump device 5 has a pump cylinder 23, a pump piston 22, and an annular magnet arrangement 28, 46 around the pump cylinder 23. The pump piston 22 can move in the pump cylinder 23, along an axis 11. An axial closure 25 of the pump cylinder 23 closes off, with the pump piston 22, a pump volume 27 within the pump cylinder 23. The annular magnet arrangement 28, 46 has a magnetic coil 28, which encloses the pump cylinder 23 and which overlaps, along the axis 11, at least in part, with the magnetizable closure 25 and, in part, with the magnetizable pump piston 22.
