FIELD: storage procedures in machine engineering and metallurgical plants, namely cutting apparatuses. ^ SUBSTANCE: apparatus includes cutters mounted with possibility of simultaneous mutually opposite plane-parallel motion. Each cutter includes supporting edge and two protrusions formed along its length at side of reciprocal cutter. One protrusions of each cutter has plane for pressing; second protrusion of each cutter has cutting plane and cutting edge. Pressing plane of each cutter is inclined to supporting edge by angle equal and turned to opposite side relative to inclination angle of cutting plane to which cutting edge of opposite cutter belongs. Protrusion with cutting plane and cutting edge of one cutter and protrusion with pressing plane of other cutter at side of blank to be cut are made in the form of changeable plates. ^ EFFECT: enlarged manufacturing possibilities, improved efficiency, more easy operation of apparatus. ^ 3 dwg |
