Abstract

The invention discloses a press stroke and die setting height adjusting mechanism in the field of presses. The press stroke and die setting height adjusting mechanism comprises a machine body cross beam. A rotatable crankshaft is horizontally arranged on the machine body cross beam. A connecting rod is arranged on the connecting rod journal of the crankshaft. An upper toggle rod and a lower toggle rod are hinged to the ends of the connecting rod correspondingly. A guide column which can vertically move is hinged to the lower end of the lower toggle rod. A sliding block is arranged at the lower end of the guide column. A rotatable eccentric shaft is arranged in the position, corresponding to the upper toggle rod, of the machine body cross beam and is parallel to the rotation axis of the crankshaft. The upper end of the upper toggle rod is fixedly connected with the eccentric section of the eccentric shaft. The main shaft section of the eccentric shaft is sleeved with a worm gear. The machine body cross beam is provided with a rotatable worm. The axis of the worm is perpendicular to the rotation axis of the eccentric shaft. The worm gear and the worm are engaged with each other. One end of the worm is in transmission connection with a rotary driving mechanism. The press stroke and die setting height adjusting mechanism can randomly adjust the press sliding block stroke and the die setting height, can automatically adapt to dies with different specifications and workpieces with different sizes, and is convenient to adjust and savable in time and effort.
