Abstract
A support for a material being cut in an oxidation cutting operation comprising a stanchion and a tip connected to and projecting above the stanchion to contact and support a material being cut. In cross section the tip is characterized by angled sides which extend upwardly and inwardly from a base to an apex which contacts the underside of the material being cut. Such a configuration minimizes direct impingement of the oxidation stream of the cutter upon the tip and directs molten material flowing from the kerf away from the support.
Claims17
A material support for an oxidation cutting operation comprising:
- longitudinally extending stanchion means for operatively underlying and supporting, at least in part, material to be cut by an oxidation cutter, and
- longitudinally extending tip means operatively connected to said stanchion means and projecting above said stanchion means for supporting the material to be cut,
- said tip means in cross section having a recess in the bottom thereof for receiving a portion of said stanchion means, and angled side portions, said side portions extending from a base portion inwardly and upwardly from said base portion to define an upwardly directed acute vertex for contacting an underside of the material to be cut to minimize direct impingement of the oxidation stream upon said tip means and to direct molten material, from a kerf in the material to be cut, away from said tip means, and
- said tip means being constructed of material with a thermal conductivity greater than the thermal conductivity of said stanchion means and having a mass substantially greater than the mass of said portion of said longitudinally extending stanchion means to distribute and dissipate within said tip means hot spots generated upon said tip means by the oxidation cutter.
A work table for supporting a material to be cut by an oxidation cutting operation comprising:
- a generally planar work surface;
- a plurality of vertical, longitudinally extending stanchion means positioned upon said work surface for operatively underlying and supporting material to be cut by an oxidation cutter;
- and
- a plurality of longitudinally extending tip means, at least one connected to each of said stanchion means and extending between said stanchion means and the material to be cut,
- each of said tip means in cross section having a recess in the bottom thereof for receiving a portion of the stanchion means to which such tip means is connected and having angled sides extending from a base portion upwardly and inwardly to define an upwardly directed acute vertex for contacting an underside of the material to be cut to minimize direct impingement of the oxidation stream upon said tip means and to direct molten material, from a kerf in the material to be cut, away from said tip means, and
- each of said tip means being constructed of material with a thermal conductivity greater than the thermal conductivity of said stanchion means and having a mass substantially greater than the mass of said portion of said longitudinally extending stanchion means to distribute and dissipate within said tip means hot spots generated upon said tip means by the oxidation cutter.
In a work table for supporting a material to be cut by an oxidation cutting operation, the work table including a stanchion for supporting in a horizontal position, material to be cut by the oxidation stream
- the improvement comprising:
- tip means removably mounted on the stanchion to project above the stanchion for directly supporting the material to be cut,
- said tip means in cross section having a recess in the bottom thereof for receiving a portion of said stanchion, and upwardly and inwardly converging side portions forming an upwardly directed acute vertex for contacting an underside of the material to be cut to minimize direct impingement of the oxidation stream upon said tip means and to direct molten material, from a kerf in the material to be cut, away from said tip means, and
- said tip means being constructed of material with a thermal conductivity greater than the thermal conductivity of said stanchion and having a mass substantially greater than the mass of said portion of said longitudinally extending stanchion to distribute and dissipate within said tip means hot spots generated upon said tip means by the oxidation cutter.
