United States Patent 3,315,511 DEBURRING DEVICE FUR SLIT STEEL STRIPS Douglas A. Turner, Box 109, Salem, Ohio Filed Sept. 19, 1954, Ser. No. 395,493 6 Claims. (1. 72-221) This invention relates to deburring devices which will effectively deburr the longitudinal edges of slit steel strips.
The principal object of the invention is the provision of a deburring device that will remove burrs formed on the longitudinal edges of slit strips.
A further object of the invention is the provision of a deburring device that will maintain the gauge or thickness of the slit strip along the longitudinal edges thereof while deburring the same.
A further object of the invention is the provision of a deburring device that will maintain the gauge or thickness of slit strip passed therethrough and simultaneously deburr the longitudinal edges thereof and simultaneously maintain tension thereon so that the slit strip may be uniformly recoiled.
A still further object of the invention is the provision of a deburring device for a slit steel strip which may be operated continuously and automatically when located, for example, between a slitter and a recoiler.
A still further object of the invention is the provision of a deburring device that may be easily disassembled and the deburring elements changed to conform to the width of the slit strips to be deburred thereby.
A still further object of the invention is the provision of a deburring device for treating the longitudinal edges of slit steel strip and the like so as to maintain a desired configuration thereof and remove longitudinally extending burrs therefrom, and which will simultaneously maintain the desired gauge of the slit strip being deburred, by imparting a rolling mill action thereto simultaneously with its deburring action.
The deburring device disclosed herein is particularly useful in connection with processing steel strip of mill width into commercially desirable slit strips. Such slit strip steel is commonly supplied to users who then feed the coils of slit strip directly into processing machines, such as automatic blanking and stamping dies in suitable press arragements to fabricate desirable objects directly therefrom.
In the past, the slit steel strip has commonly had longitud'mally extending burrs on the edges thereof where the strips were slit from the original mill width of rolled steel. Devices heretofore proposed in the art for deburring the edges of slit steel strip have approached the problem by attempting to engage the opposite longitudinal edges of the slit strips in annular rotary dies having peripheral grooves therein engaged upon the longitudinal edges of the strip to be deburred. Such devices, while effecting a deburring operation, actually deform the edges of the strip and in many cases reduce it to a dog bone shape wherein the longitudinal edges of the slit strip are thicker This complicates the recoiling of the slit strip, and, more importantly, renders it difiicult in handling and feeding the strip to suitable automatic equipment for blanking and shaping articles therefrom.
It is, therefore, one of the principal objects of this invention to produce a deburring device which will actually and completely deburr the longitudinal edges of the slit steel strip passed therethrough and at the same time maintain the gauge of the slit strip uniformly thereacross and including the edge portions thereof.
A further disadvantage in the deburring devices heretofore known in the art has comprised the inability of the devices to maintain tension on the strip being deburred with the result that the strips fed to a recoiler would not be recoiled in uniform tension and an unwieldy and loosely coiled product results. The deburring device disclosed herein overcomes all of these objections heretofore found in connection with deburring the longitudinal edges of slit strip steel and at the same time facilitates the recoiling by maintaining uniform tension on the slit steel strips being passed therethrough and deburred thereby and the same are therefore capable of uniformly tensioned recoiling, which is highly desired.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
The invention is illustrated in the accompanying drawing, wherein:
FIGURE 1 is a side elevation of a deburring device formed in accordance with the invention.
FIGURE 2 is section on line 22 of FIGURE 1.
FIGURE 3 is an enlarged detail of a portion of the deburring device seen in FIGURE 2, with parts broken away and parts in cross section.
FIGURE 4 is an enlarged detailof a portion of the deburring device seen in FIGURES 2 and 3 of the drawings and illustrating portions of slit strip therein.
FIGURE 5 is a symbolic diagram illustrating the positioning of the top and bottom forming stands of the deburring device in a steel strip slitting line.
By referring to the drawings and FIGURES l and 2 in particular, it will be seen that a stand comprising a pair of spaced vertical supports It 10 is disclosed and wherein a pair of horizontally positioned rolls 11, 11 having necks 12, 12 are journalled in anti-friction bearings 13, 13 which in turn are located in the spaced vertical supports it 10' of the stand.
The bearings assemblies 13, 13 are mounted in support members 14, 14- Which in turn are secured to the spaced vertical support members It 10 of the stand as will be understood by those skilled in the art. The arrangement and mounting of the horizontally positioned rolls 11, 11 is such that they may be readily removed and replaced when desired.
Positioned in vertically spaced relation above the rolls 11, 11 and centered vertically thereabove, there is a smooth surfaced roll 15, which smooth surfaced roll 15 is provided with necks 16, 16 which are jourualled in anti-friction bearings 17, 17 and these are in turn supported by support members 18, 18 which are arranged for vertical movement relative to the spaced vertical supports 10, 16 of the stand in which the several rolls are mounted.
Means (not shown) is provided for moving the support members 18, 18 and the smooth surfaced roll 15 vertically and means may be seen in FIGURE 1 of the drawings for holding the support members 18, 18 in desired position. The holding means comprises wedgeshaped elements 19, 19 engaged against angular lower surfaces 20, 20 of the oppositely disposed support members 18, 18. The wedge- shaped members 19, 19 are arranged to be moved longitudinally by means of screws 21, 21 threadably engaged therein and held against longitundinal motion by a mounting bracket 22. It will thus be seen that the smooth-surfaced roll 15 may be elevated relative to the rolls 11, 11 heretofore referred to so as to permit an idler roll 23 to be positioned therebetween and then repositioned in desirable relation thereto. The
' 11, 11 heretofore referred to.
3 idler roll, which is best illustrated in FIGURES Z and 3 of the drawings, comprises an elongated cylindrical member 23 having a plurality of individual annular roll segments 24, 24 disposed thereon and held in side-by-sidej 'relation. The annular roll segments 24, 24 are preferably formed of a metal carbideso that they will be relativelyhar-derthan the rolls 11, 11 on which they rest and relatively harder than the smooth surfaced roll 15 which is in contact therewith. The idler roll 23 has an elongated neck section 25 with an annular guide ring 26 thereabout which is adapted to run in registry with guide channels'27 and 28 formed, respectively, in the smooth surfaced roll 15 and the horizontally positioned rolls a Each of the annular roll segments 24 has a centrally disposed rib 29, and the space between adjacents ribs 29 on adjacent annular roll segments 24 equals the width of the slit strip passed through the device for deburring the longitudinal edges thereof.
It will also be seen that the horizontall positioned rolls 11, 11 are provided with a plurality of annular grooves 30, -30 which are positioned to match the ribs 29, 29 of the annular roll segments 24 so that the ribs do not actually engage the horizontally positioned rolls 11, 11. The idler roll 23 with its annular roll segments 24 therefore rests on the horizontally positioned rolls '11, 11. The smooth surfaced roll 15 engages the periphery of the ribs 29, 29 thereof. The ribs 29, 29 are of a height equal ,to the gauge or thickness of the slit strip being deburred and with the roll 15 work the burred edges of the slit strip.
Still referring to FIGURE '2 of the drawings, it will be seen that in the form of the invention chosen for illustration, six of the annular roll segments 24 are illus- I hated inposition on the elongated cylindrical member comprising the idler roll 23 and that each of the six annular roll segments has an annular rib 29 thereon so that there are five spaces between the respective annular ribs 29, 29 through which slit strip 'maybe passed. 'It
will further be seen, by referring to FIGURE 3 of the drawings, which is an enlarged detail, that the sidesoi the annular ribs 29, 29 are shaped in a desirable manner so that sections'of the slit strip SS running through the deburring device on the pass line thereof will be firmly engaged between the lower portion of the smooth surface-d roll-15 and the upper surfaces of the annular roll segments 24, 24.
. By referring to FIGURE 4 ofithe drawings wherein a-greatly enlarged detail of portions of adjacent annular,
.By referring now to FIGURES of the drawings, the
then move through a first deburring stand carrying the legend fTop Former. wherein the deburring idler roll is positioned as heretofore described and illustrated in FIGURES l, 2 and 3 of the drawings, the samebeing indicated by the reference numeral 23,*and wherein the smooth surfaced roll 15 is shown above the slit strip sections SS and the grooved horizontally positioned rolls 11, 11 are shown positioned below and in supporting relation to the idler roll 23. r Y
The slit strip sections SS passing through the top former stand of the de-burring device will have their lower longitudinal edges deburred as hereinbefore described and illustrated and particularly with respect to FIGURE 4 of the drawings. These partially deburredjslit strip sections SS now move to a second stand which bears the legend Bottom Former and wherein the idler roll 23 is positioned above the slit strip sections and carries the reference numeral 23A. The smooth surfaced roll 15A is positioned below the slit strip sections SS and the two horizontally positioned grooved rolls which back up the idler roll 23A are positioned thereabove.
it wiil be observed that the continuous tension on each of the slit strip sections SS is thereby maintained throughout the two stands of the deburring device and that as the completely deburred slit strip sections SS move from the bottom former stand with their upper longitudinal edges deburred thereby, they will be held under proper tension so, that they may be compactly and tightly recoiled by a recoiler generally indicated by the numeral 34;
It will occur to those skilled in the art that thenovel deburring action thus performed on the longitudinal edges of the slit strip sections SS .is efiiciently done and that there is no deformation or thickening of the longitudinal edges of the slit strip sections SS as would be expected to occur with deburring devices heretofore known in the art. I
The problem of recoiiing the 'slit strip sections SS is also facilitated by the device which maintains constant full surface engagement and tension on the slit str'ip sectionsSS at all times, and thereby avoids looseness or slack.
in anyone of the slit strip sections so that they are evenly. and tightly recoiled in. a highly desirable manner. V
7 It will thus be seen that a novel and eificient deburring 7 device for deburring the longitudinal edges of slit strip steel sections has been disclosed which meets the several 7 objects of the invention, and having thus described my invention, what I claim is:
llfA deburring device for slit strips comprising an idler roll having a plurality of longitudinally spaced annular ribs thereabout, a plurality of supporting rolls for said idler'roll, at least one of-said plurality of supporting rolls having a smooth surface in engagement with'the.
