Full-automatic press machine

The utility model discloses a full-automatic press machine which structurally comprises a placing table, a placing groove, a buffering mechanism, a sliding block, a guide column and a sliding mechanism, the placing groove is embedded in the upper end of the placing table, the buffering mechanism is located in the placing groove, after extrusion assembly is completed, a punching head resets and moves upwards, at the moment, extrusion force on a bearing is lost, and the bearing is prevented from being damaged. A spring guide rod at the bottom applies reset elastic force to a hinged sliding block, so that a linkage rod performs linkage, a bearing placed at the upper end of a bearing plate is ejected out of a placement groove, and the assembled bearing is conveniently taken out from the interior of the placement groove; when the bearing is placed in the placing groove, the abutting wheels can elastically abut against the outer ring of the bearing through elastic cooperation of the connecting plates and the compre
