Abstract
A cutting apparatus embodying the principles of the present invention includes first and second cutting torches which can be selectively operated, depending upon the nature and thickness of a workpiece which is being cut. The cutting apparatus includes a pivotally moveable torch mounting plate on which each of the first and second torches is mounted, with the mounting plate in turn being rotatably moveable about a vertical main axis of the apparatus. The present apparatus provides significant savings, in that two individual torches, such as an oxy-acetylene gas torch and a plasma torch, and can be mounted on the same mechanism for positioning to produce bevel and vertical cutting in materials having different thicknesses and/or cutting requirements at a significant savings in machine complexity.
Claims16
An apparatus for cutting a workpiece, comprising:
- a main support frame defining a main axis extending through the main support frame;
- a torch mounting plate mounted on and depending from said support frame, said torch mounting plate being pivotally movable about a pivot axis that intersects said main axis at a right angle thereto;
- a first cutting torch mounted on said torch mounting plate;
- and
- a second cutting torch mounted on said torch mounting plate,
- said torch mounting plate being selectively movable about said pivot axis to selectively position a selected one of said first and second cutting torches for cutting said workpiece.
An apparatus for cutting a workpiece, comprising:
- a main support frame defining a main axis extending through the main support frame;
- a rotatable torch support depending from and mounted on said main support frame for rotation with respect thereto about said main axis;
- a torch mounting plate mounted on and depending from said torch support for rotation therewith about said main axis relative to said main support frame, said torch mounting plate being pivotally movable with respect to said torch support about a pivot axis that intersects said main axis at a right angle thereto;
- a first cutting torch mounted on said torch mounting plate, said first cutting torch being axially movable relative to said torch mounting plate along a first cutting axis that intersects said pivot axis;
- and
- a second cutting torch mounted on said torch mounting plate, said second cutting torch is axially movable relative to said torch mounting plate along a second cutting axis that intersects said pivot axis,
- said torch mounting plate being selectively movable about said pivot axis to selectively position a selected one of said first and second cutting torches for cutting said workpiece.
