Definitions
- the apparatus has particular application in contouring the edges of metal strip being drawn through an edge contouring station delined by a heat source.
- the heat source is mounted on a yoke that moves in response to the lateral thrust of the metal strip as it oscillates from side to side and means are provided to maintain the heat source at a fixed distance from the edge of the strip during oscillation.
- This invention relates to a proximity yoke apparatus for controlling spacing between the Isides of a moving strip and edge treatment means and more particularly to edge contouring apparatus.
- This invention is in a proximity yoke apparatus for controlling spacing between the side of a moving strip and edge treatment means, such as heat source. It includes a supporting frame with a yoke mounted on the frame to oat side to side on the frame in response to the transverse oscillatory movements of a strip being fed longitu dinally through the apparatus. Guide means, which are xed on the yoke, for receiving the moving strip and aligning it n a fixed position on the yoke and movable therewith also define an edge treatment station for the strip.
- Edge ⁇ treatment means are positioned adjacent at least one edge of the strip at the edge treatment station; the edge treatment means are adjusably mounted on the yoke and movable therewith so that a fixed space will be maintained between the edge treatment means and the edge ofthe strip during floating movement of the yoke.
- the guide means includes a pair of rollers mounted on each side of the strip to contact opposite edges of the strip and the edge treatment means is posi- ⁇ 3,545,244 Patented Dec. 8, 1970 on the yoke greater latitude in side-to-side movement of the strip is permitted.
- FIG. 1 is a top view of apparatus of the invention; and FIG. 2 is an enlarged side elevation, partly in section, taken along line 2-2 of FIG. 1.
- the preferred embodiment is apparatus for edge contouring metal strip by heat. As shown, it includes a supporting frame structure 1l) on which is mounted a yoke assembly 11.
- the supporting frame structure 10 ⁇ includes laterally spaced horizontally extending beams 12 and
- a pair of spaced rollers is mounted on each beam, with each pair of rollers being in alignment with the other to receive the yoke assembly 11 and permit it to float thereon laterally with respect to the longitudinal extension of beams L2 and 13.
- the yoke assembly .11 is composed of a frame defined by two longitudinally extending spaced plates 18 and 19 which are connected by two parallel end rods 20 and 21 dimensioned to seat in the rollers 14, I15, 16, and 17; a
- ⁇ center supporting rod 22 is positioned between rods 20 and 21 and joined to the plates.
- the yoke can move laterally on the rollers in a plane parallel to the plane of the moving strip and in a direction normal to the longitudinal direction of strip travel.
- a guide assembly 23 for receiving a moving strip and aligning it with respect to the yoke assembly so as to define an edgecontouring station 24.
- the guide assembly 23 is mounted to the center supporting rod 22 by clamps 24 and 25 which have integral upright supports 26 and 27 which are internally threaded to receive a suitable assembly for pivotally mounting longitudinal horizontally extending brackets 28 and 29 to the upright supports. Evenly spaced in each bracket from the pivot point are pairs of rollers 30 and 31. Each roller is fully rotatable in the plane of the strip and grooved so that the strip will not slip out from between the pairs of rollers.
- Each bracket is adjusted on the center rod to accommodate the size strip being processed and when the strip is inserted in the rollers as shown in FIG.
- the strip is aligned on the yoke and can be rapidly moved through the guide assembly as the yoke floats side-to-side without binding.
- pivotally mounting the bracket By pivotally mounting the bracket, slight lateral movement of the rollers is permitted to compensate for slight changes in the angle of feed of the strip into the guide assembly and irregularities in the strip itself.
- tungsten inert gas heating elements 34 and 35 are mounted on the center supporting rod 22 by means of adjustable clamps 32 and 33. While two heating elements are shown, it is of course within the scope of the invention to use only one heating element whenever desired.
- the adjustable clamps the heating elements are adjusted on the center supporting rod 22 until the ends 36 and 37 of the heating elements are spaced a predetermined distance from the edge of the strip.
- the space between the metal strip and the ends of the heating elements may be adjusted vertically by adjustment knob 38 and horizontally by adjustment knob 39.
- the ends of the heating elements are located over the pivot point of the bracket so that the slight pivoting permitted by the guide assembly will not affect the fixed spacing between the heating element and the edge of the strip.
- metal strip 40 is unwound from one supply roll and fed over a first tension roll 41 which is mounted on the supporting frame so that the top of the roll is subs'tantially the same 'plane as the rollers of the guide assembly.
- the strip is moved at speeds of about 30 feet per minute through the guide assembly where the edges are rounded by the application of heat from the heating elements.
- the strip passes over a second tension roll 42 mounted atthe outlet end of the apparatus in the same manner as the lirst roll; then the metal strip is v either rewound onto a supply roll or is passed to further processing stations.
- Proximity yoke apparatus for controlling spacing between the side of a moving strip and edge treatment means comprising:
- guide means lixed on the yoke for receiving the moving strip and aligning it in a xed position on the yoke and defining an edge treatment station for the strip;
- edge treatment means positioned adjacent at least one edge of the strip at the edge treatment station, the edge treatment means being adjusably mounted on the yoke and movable therewith so that a fixed space will be maintained between the edge treatment means and the edge of the strip during floating movement of the yoke.
- edge treatment means is a heat source for rounding the edge of metal strip by melting.
