METHOD OF OPERATING HAND-HELD MOTOR-DRIVEN PRESS AND HAND-HELD MOTOR-DRIVEN PRESS Russian patent published in 2013 - IPC B25B27/10 B25B28/00 B21J9/14 H01R43/04 

FIELD: process engineering.

SUBSTANCE: invention relates to hand-held tools. On switching on the press, one or several press jaws displace from initial position into working position unless preset pressing force is reached or preset time lapses. Thereafter, said press jaws automatically open. Press jaws opening can be interrupted before reaching of initial position at intermediate position to start the nest pressing cycle from said intermediate position. Magnitude of displacement, or time, or pressure whereat jaws opening can be interrupted before reaching of initial position at intermediate position to start the nest pressing cycle from said intermediate position is recorded and saved.

EFFECT: definite pressing pressure is maintained.
