Abstract
A machine for machining sheet metal and presenting: a multiple-tool assembly fitted with a number of tools arranged in a ring about a vertical axis; a multiple-die assembly fitted with a number of dies arranged in a ring about a vertical axis; a work station presenting a hammer movable along a vertical axis; and a carriage for moving the sheet. The main characteristic of the present invention is that the work station presents a striker for transmitting to the work tool the pressure exerted by the hammer; and a device for rotating the work tool about is longitudinal axis.
Claims13
A machine for machining a metal sheet said machine comprising:
- a top and bottom cylindrical turret rotating about and coaxial with each other along a first vertical axis;
- plurality of multiple-tool assemblies arranged in a ring about the periphery of said top turret, each multiple-tool assembly rotatable about a second vertical axis;
- a plurality of multiple-die assemblies arranged in a ring about the periphery of said bottom turret, each multiple-die assembly rotatable about the second vertical axis;
- a work station including a hammer movable along the second axis;
- and
- an electronic control unit for controlling a carriage for gripping and moving said metal sheet, a means for driving said turrets, a means for driving said multiple-tool and multiple-die assemblies, and a means for driving said work station;
- wherein at least one of said tools of said multiple-tool assemblies is a punch tool and at least one of said tools of said multiple-tool assemblies is a threading tool for internally threading a hole formed in said sheet;
- wherein said work station comprises a striker for transmitting to a work tool the pressure exerted by said hammer and wherein a plurality of devices for rotating said at least one punch tool and at least one threading tool about a third vertical axis is provided.
A machine as claimed in claims l, 2, 3, or 4, wherein said holder of said multiple-die assembly presents, in said second ring, a number of equally spaced second through holes, each seating a respective said die;
- said second holes being formed along a respective said axis coaxial with said third axis of the corresponding said tool.
