摘要
(KR101722782) PURPOSE: A hydraulic fine-blanking head for a press and an in-feeding method thereof are provided to prevent the axial backlash between adjusting elements during cut since an adjusting unit and a fine-blanking head are integrated.  CONSTITUTION: An in-feeding method of a hydraulic fine-blanking head(3) for a press is as follows.  The movement thread(12) of an adjusting nut(6) and the movement thread(13) of a main cylinder(10) are hydraulically locked in an axial direction.  After the generation of the pressure and the force, the two movement threads are released by the switching off of the fluid and the movement threads of an adjusting mechanism move a backlash.  The fluid is blocked, a hydraulic motor is switched off and the driving shaft of the motor stops by a brake.  The locking pressure for movement threads is again switched on and the movement threads do not have the backlash on the line of force.
