CUTTING FLUID CATCH MECHANISM

Abstract

The invention relates to a device for attachment to a metalworking device or a chip conveyor designed to capture fluid used in the machining process so that the fluid can be reused. More specifically, the cutting fluid catch mechanism provides a slanted surface such that the metal swarf, the pieces of metal or debris resulting from machining operations slides down the slanted surface but the cutting fluid is captured by the catch mechanism and directed to a cutting fluid reservoir where it can be filtered and reused.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Now referring to the drawings in detail, wherein like reference numerals refer to like elements throughout, FIG. 1 shows a top elevational view of drip tray 11. Drip tray 11 comprises a planar rectangular surface 13, a pair of side walls 15, 17 shown in FIG. 2 and FIG. 3 protruding upwardly from the planar rectangular surface 13 and a flange 19, 21 extending outwardly from each of the pair of side walls 15, 17. Each flange 19, 21 may further comprise a plurality of apertures 23. Generally speaking, apertures 23 may be used to suspend the drip tray 11 from a metalworking machine or chip conveyor. Drip tray 11 further comprises a curl 25 at one end. Curl 25 is comprised of at least two sections, a first upwardly angled section 27 being angled upwardly from the generally planar rectangular surface and a downwardly curved section 29 which is curved downwardly relative to the short upwardly angled section 27 such that the short upwardly curved section 27 curves below the plane of the generally rectangular planar surface 13. As an example, as shown in FIG. 13 drip tray 11 may be suspended from the metalworking machine using wire attached via one or more of the apertures 23. Drip tray 11 is installed such that the end opposite the curl 25 is higher than the end with the curl 11 such that the cutting fluid flows downhill to the curl 25.

[0022] Referring now to FIGS. 4-7, which show several views of the drip reservoir 31. The drip reservoir 31 can be of virtually any shape provided that it collects cutting fluid that flows down the flat rectangular surface 13 of the drip tray 11 to the curl 25 in the drip tray 11. As shown in FIG. 5, drip reservoir 31 comprises a bottom surface 33, and two generally upwardly extending side walls 35, 37 and two generally upwardly extending end walls 39, 41. In the embodiment shown in FIG. 5, the upwardly extending side walls 35, 37 each further comprise a flange 43, 45. Each flange 43, 45 may further comprise apertures 47 for use in attaching drip reservoir 31 to drip tray 11. Drip reservoir 31 further comprises an aperture 49 in one of the side walls 35, 37. As shown in FIG. 13, a hose 51 can be attached aperture 49 to drain drip reservoir 31 of cutting fluid.

[0023] In operation, as metal schwarf and cutting fluid is ejected from a metalworking machine, the schwarf lands on the drip tray 11. At that point the cutting fluid has the opportunity to run down the drip tray 11 and over the curl 25, where it drops in the drip reservoir 31. Metal schwarf simply slides down the drip tray 11 and over the curl 25 into a recycling bin.

[0024] Drip tray 11 is attached to drip reservoir 31 in a sliding relationship such that, if necessary, the position of the drip reservoir 31 can be adjusted relative to the drip tray 11. Depending on the installed angle of the drip tray 11, the drip reservoir 31 may need to be extended outwardly to catch cutting fluid. Steeper drip trays 11 may require a fully extended drip reservoir 31. Shallower drip trays 11 may require less extension or schwarf will land in the drip reservoir 31. To permit this extension and retraction function, the drip tray 11 further comprises slots 27. Fasteners (not shown) are inserted through drip reservoir 41 apertures into slots in drip tray. When fasteners are loosened, drip reservoir 31 may be adjusted relative to drip tray 11.

[0025] Preferred embodiments of this invention are described herein. Variations of those preferred embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.
