Patent ID: 8563894

Claim:
A machine for punching and laser cutting of a flat sheet metal, the machine comprising: a fixed base; a linear guide fixed to a lateral side of said base and being arranged to extend in a direction parallel to the plane of the sheet metal; a fixed punching head; a mobile laser cutting head; a compass structure which supports said laser cutting head such that said laser cutting head can pivot about an axis perpendicular to the plane of the sheet metal, said compass structure extending laterally from said linear guide and being movable along said linear guide; and a manipulator for movement of the sheet metal in a Cartesian plane (XY), wherein said compass structure includes: a first sliding pad; a second sliding pad; a first rod having a first end and a second end, said first end of said first rod being pivotably connected to said first sliding pad such that said first rod is pivotable about a first axis perpendicular to the plane of the sheet metal, and said second end of said first rod being integrally fixed to said laser cutting head; a second rod having a first end and a second end, said first end of said second rod being pivotably connected to said first sliding pad such that said second rod is pivotable about a second axis perpendicular to the plane of the sheet metal, and said second end of said second rod being pivotably connected to said second end of said first rod such that said second rod is pivotable relative to said first rod about a third axis perpendicular to the plane of the sheet metal; a first actuator which drives said first sliding pad along said linear guide; and a second actuator which drives said second sliding pad along said linear guide, wherein said first rod and said second rod are arranged to form a V-shape for articulated connection of said first sliding pad and said second sliding pad to said laser cutting head, and wherein the first actuator moves the first sliding pad independently of the second sliding pad, and the second actuator moves the second sliding pad independently of the first sliding pad.
