Rotating embossing head for inscribing metal workpieces, tools or plates comprises a rotating element impinged upon by a fluid under pressure to produce a rotating movement transferring impact forces to a force-absorbing surface

摘要

Rotating embossing head (1) comprises a support sleeve (3) containing a part (4) moving along a movement axis (12) and having a needle (8) guided along the movement axis by at least one guide element (13, 15) and protruding out of the support sleeve, a force-absorbing surface (11) for the needle, and a restoring device (14) arranged between the support sleeve and the moving part to restore the moving part. A rotating element (21) rotatably arranged about an axis of rotation (21a) in a control housing (20) is impinged upon by a fluid under pressure to produce a rotating movement. The rotating movement transfers impact forces to the force-absorbing surface via a transfer device. Preferred Features: The rotating element is a turbine element having a paddle region (23) with radially protruding projections.
