CUTTING WATER TABLE AND METHODS OF USE

摘要

A water table for cutting metallic materials comprises an upper water pool supported above a false vessel bottom. The surface of the upper pool water volume is regulated relative to workpiece support rails secured above the upper pool surface. An actual vessel bottom is positioned below the false bottom and supports a lower pool volume. Bearing directly upon the lower pool surface is an enclosed air pressure volume regulated by an air supply source. The upper and lower pool volumes are hydraulically linked by flow conduits. A frangible rupture disc in a pressure release vent assures an absolute pressure limit within the air volume to avoid over-pressurization or under-pressurization of the water table.

主权项

1. A metal cutting water table comprising:
a vessel comprising a primary water volume located beneath a plurality of support rails, wherein the support rails are secured to the vessel in parallel alignment along a common support plane, wherein the vessel additionally comprises a secondary water volume beneath the primary water volume, and wherein the primary water volume and the secondary water volume are hydraulically linked by a plurality of water conduits; an air volume bearing upon the secondary water volume to support a predetermined surface level for the primary water volume; an air control conduit for controlling additions and reductions of air in the air volume; a pressure relief conduit opening into the air volume; and a rupture disc closing the pressure relief conduit, wherein the rupture disc ruptures to open the pressure relief conduit at a pressure differential across the rupture disc that is equal to or exceeding a predetermined value.
