Torch guide for metal cutting

摘要

The torch guide encloses a structural metal section to be cut on four sides of that metal section. The cutting torch guide has co-planar top and bottom guiding surfaces and parallel first and second side guiding surfaces. The top and bottom guiding surfaces intersect the first and second side guiding surfaces at four points lying in a same plane. All four guiding surfaces being aligned perpendicular to a longitudinal axis of the structural metal section to be cut, for guiding a cutting torch around the entire structural metal section to be cut. The top and bottom guiding surfaces are adjustable at angle of 90° to 45° from the longitudinal axis, while maintaining the alignment of all four guiding surfaces along a planar cutting plane through the structural metal section to be cut.

主权项

1. A torch guide having a longitudinal axis, comprising;
a top and bottom guiding surfaces and first and second side guiding surfaces; said top and bottom guiding surfaces intersecting said first and second side guiding surfaces at four points lying in a same plane; said four points defining a closed four-sided cutting plane for enclosing a structural metal section to be cut; said first side guiding surface having a first articulation affixed thereto; said first articulation extending along a first axis of articulation; said first articulation connecting said first side guiding surface to said top and bottom guiding surfaces for adjusting a planar alignment of said first side guiding surface relative to said top and bottom guiding surfaces; said second side guiding surface having a second articulation affixed thereto; said second articulation extending along a second axis of articulation; said second articulation connecting said second side guiding surface to said top and bottom guiding surfaces for adjusting a planar alignment of said second side guiding surface relative to said top and bottom guiding surfaces and relative to said first side guiding surface, and said first and second axes of articulation extending parallel with said closed four-sided cutting plane.
