Abstract
A metal panel shear cutter is designed for metal panels which include support ribs. The metal panel cutter utilizes an anvil type cutting blade positioned at each side of a cutting base. Each cutting blade is pivotally connected to a cutting base in the vertical plane. The cutting base also includes supports for the ribs of the panels to allow for a smooth and clean cut of the panel. The cutting blades and a small portion of the cutting base are pivotally connected to the cutting base in the horizontal plane so they may be pivoted to the desired cutting angle while the metal panel remains fixed with respect to the base. This pivotal portion of the base includes additional supports for the ribs of the panel. These supports are adjustable to accommodate the various angles at which the panels are to be cut.
Claims10
A cutter for sheet metal panels comprising:
- an elongate base plate adapted to maintain a ribbed sheet metal panel in a fixed position relative to said elongate base;
- said elongate base plate having a first base plate end wall spaced from a second base plate end wall;
- a first base plate side wall extending between said first base plate end wall and said second base plate end wall;
- a second base plate side wall spaced from said first base plate side wall and extending between said first base plate end wall and said second base plate end wall;
- a first cutting surface;
- said first cutting surface having a first cutting surface end wall spaced from a second cutting surface end wall;
- a first cutting surface side wall extending between said first cutting surface end wall and said second cutting surface end wall;
- a second cutting surface side wall spaced from said first cutting surface side wall and extending between said first cutting surface end wall and said second cutting surface end wall;
- a shear edge along said first cutting surface side wall of said first cutting surface;
- said elongate base plate and said first cutting surface being coplanar;
- said first cutting surface being pivotally connected to said elongate base plate at a junction of said second base plate end wall and said first base plate side wall;
- a shear cutting blade hingedly connected to said first cutting surface adjacent said shear edge;
- said shear blade and said shear edge cooperating to cut a metal panel placed thereon;
- whereby said first cutting surface can be pivoted with respect to said elongate base plate such that a sheet metal panel on said main portion of said elongate base table can be cut at an angle with respect to the longitudinal axis of the sheet metal panel.
