Abstract

The utility model relates to technique improvement of a machine tool, specifically to a three-point support type knife rest guider of a mechanical plate shearing machine. The three-point support type knife rest guider comprises a rack, and left and right guiders and left and right sliding knife rests on both sides of the rack, and is characterized in that left and right guiders employ three-point support guiding structures, which means that a spring compact rolling support is installed on the front side of sliding knife rests at each side of the rack, and two fixed rolling supports in upper-lower arrangement are arranged on the rear side. The three-point support type knife rest guider solves the problem that the slide knife rest of a conventional mechanical plate shearing machine employs a flat type guide rail structure which has gaps between a guide pair, is easily wearing, is difficult for adjusting, and affects the stability of the gap between blades. The utility model is applicable to modification of the guide pair of a mechanical plate shearing machine.
