Abstract
An edge trimmed piece that is cut from a long metal slab with a cutting torch carried along the slab edge is automatically crosscut into short manageable length pieces with a secondary crosscutting torch. Both torches are mounted on the same carriage and the crosscutting torch is periodically activated to move along an acute angular path with respect to the edge trim cut, resulting in an effective crosscut transverse to the main trim cut. The crosscutting operation may be carried out without interruption of the edge trim torch, thereby enhancing productivity and trim cut quality.
Claims10
An apparatus for simultaneously edge-cutting a metal workpiece and crosscutting the edge-cut piece into manageable lengths comprising:
- a carriage mounted horizontally over the workpiece and movable relative to the workpiece in the direction of the desired edge cut and at a selected edge cutting speed;
- an edge cutting torch mounted on the carriage for movement therewith along a path of the edge cut;
- a crosscutting torch mounted on the carriage for movement therewith and for independent horizontal cutting movement across the edge-cut piece, at an acute angle to the path of the edge cut and at a selected crosscutting speed;
- and
- means for adjusting at least one of the angle of movement and the crosscutting speed to provide a crosscut generally transverse to the edge cut.
A method for simultaneously edge-cutting a metal workpiece and crosscutting the edge-cut piece into manageable lengths, said method comprising the steps of:
- (1) positioning a carriage for horizontal movement over and relative to the workpiece in the direction of the desired edge cut and at a selected edge-cutting speed;
- (2) mounting an edge-cutting torch on the carriage for movement therewith along a path of the edge cut;
- (3) mounting a crosscutting torch on the carriage for movement therewith and for independent horizontal cutting movement across the edge-cut piece at an acute angle to the path of the edge cut and at a selected crosscutting speed;
- and
- (4) adjusting one of the angle of movement and the crosscutting speed to provide a crosscut which is generally transverse to the edge-cut.
