Patent ID: 7036806

Claim:
An electrically operated pressing tool ( 0 ) comprising: a spindle ( 14 ) for connecting tubular workpieces, with a fork-shaped receiver ( 3 ), a clamping pincer ( 4 ) exchangeably held in the fork receiver ( 3 ) by a connection bolt ( 5 ) and with a controlled electric drive motor ( 10 ) for actuating the clamping pincer ( 4 ), a spindle ( 14 ) driven by the electric drive motor ( 10 ) via a reduction gear ( 11 ) in active connection with the clamping pincer ( 4 ), the spindle ( 14 ) connected to the gear ( 11 ) via a shaft ( 13 ), the shaft ( 13 ) passing through at least one radial bearing ( 19 ) and an axial thrust bearing ( 18 ) supported on a housing ( 21 ) of the pressing tool, and between the thrust bearing ( 18 ) and the support on the housing ( 20 , 21 ) a force or pressure sensor ( 25 ) arranged which on reaching a predefined nominal value of the clamping force emits a switching signal (S) to a control ( 22 ) of the electric drive motor ( 10 ).
