  • the present invention relates to a sheet metal cutting device incorporating a bottom blade mounted integrally on a sheet feed table, a top blade borne in apivotable beam and a transverse blade mounted perpendicularly to the latter.
  • the object of the invention is to introduce a sheet metal cutting device which permits extremely rapid and precise cutting to size of rectangular plates. It is characterized by the fact that the transverse blade is arranged to pivot about the axis of the pivotable beam in a vertical plane perpendicular to the cutting level of the top blade and is guided at the sides by adjustable guide elements. This permits one to cut a plate to a desired rectangular size with two cuts anda single turn.
  • transverse blade which functions as a top blade, to be mounted to pivot on a lateral prolongation of the axis of rotation of the pivotable beam.
  • the two top blades are movable individually toward and away from each other and independently of one another and each operable by its own separate actuating element.
  • FIG. 1 shows a diagrammatic view from above of the proposed device
  • FIG. 2 shows a section in accordance with the line A-A in FlG.ll;and
  • FIG. 3 shows a section in accordance with the line B-B in FlG. 1.
  • the proposed sheet metal cutting device incorporates a plate feed table 1 in which are mounted a first bottom blade 2 and a second bottom blade 3 at right angles to it.
  • a beam 4 capable of being pivoted about the two shafts 5 and 6 and incorporating a first top blade 7.
  • a second top blade 9 is mounted to pivot on a prolongation 8 of the shaft 6. The top blade 7 operates in conjunction with the bottom blade 2 and the top blade 9'with the bottom blade 3.
  • the two pairs of blades are connected to a mechanical, electrical or hydraulic driving device not illustrated.
  • the top blade 9 is guided at the sides by guiding elements 10, 10, 10', 11 and 11', and these-guiding elements are adjustable.
  • the uncut plate is fed into the sheet metal cutting device and both pairs of blades are actuated simultaneously.
  • the plate is then withdrawn, turned about diagonally and again cut with both pairs of blades simultaneously. It is thus possible to cut the plate to the desired rectangular size with two cuts and a single turn.
  • a sheet metal cutting device comprising a sheet feed table on which a bottom blade and atransverse bottom blade are integrally mounted at right angles to each other, a first top blade mounted on a pivotable beam, a transverse top blade mounted perpendicularly to said first top blade, said transverse top blade being pivotably mounted on a lateral projection along the axis of said pivotable beam and moving in a vertical plane perpendicular to the cutting plane of the top blade, guiding means at the sides of each of said two top blades including adjustable guide elements.
  • a sheet metal cutting device in accordance with claim 1 including actuating means for independently and separately operating each of said two top blades.
