Definitions

  • This invention relates to the cold roll-forming of sheet metal articles wherein discrete longitudinally extending bands or zones of the article are plastically strained by cold-working during the roll-forming operation.
  • the cold-working may comprise knurling the bands or cold-reducing them.
  • Cold roll-forming sheet metal articles is a well known process. Briefly stated, a sheet metal workpiece is passed through a sequence of stands of forming rolls. Each stand produces some modification of the cross-sectional shape of the workpiece as received by the stand, and their combined effect is to bring the workpiece in a step-by-step manner into the shape of the required article. It is also known for at least one of the roll-forming stands to impress a surface pattern or otherwise cold work the workpiece in a manner not substantially modifying its cross-sectional shape. For example, one stand of rolls may knurl one or more bands of the workpiece. Indeed, the invention was developed with knurling in mind and is described primarily with reference to that mode of cold working hereinafter.
  • the invention is applicable to other cold working processes wherein the working is restricted to such bands or zones.
  • the invention is applicable to the production of roll-formed sheet steel articles wherein narrow bands of the article are cold-reduced in thickness, so as to work harden the bands and thereby stiffen the finished article.
  • the knurling process comprises pressing a tool against the metal surface to impress a pattern therein.
  • a typical knurling pattern comprises two sets of closely spaced, parallel, thin, rectilinear grooves in the knurled surface, with the grooves of each set intersecting the grooves of the other.
  • the pattern then becomes a regular grid of small, closely spaced mounds, each being a quadrilateral bounded by short lengths of groove.
  • the grooves frequently cross each other obliquely, for example with an included angle of 60° between intersecting grooves, so that each quadrilateral is diamond shaped.
  • Knurling may be applied to an article for various reasons, for example to increase the coefficient of friction so as to render an article less slippery, to provide a key for adhesive or the like, to camouflage surface defects, or simply for its ornamental effect.
  • a sheet metal workpiece having a cold- worked band extending therealong is stress relieved by superimposing a regular embossed pattern on said band, that is to say by pressing a substantially regular array of small portions of that band from the plane of the sheet.
  • the number, size, shape and spacing of the embossments (the displaced portions) are largely matters of choice that may be determined, for the most part, by cosmetic considerations, provided that the embossments form a pattern that is uniform and of sufficiently small scale to ensure that the act of forming the embossed pattern as aforesaid would cause effectively uniform contraction in at least the longitudinal direction of the embossed band.
  • the degree of that contraction may be set or adjusted by setting or adjusting the extent to which the embossments project from the plane of the sheet.
  • one or two trial runs may be made before commencing production, and the extent of the displacement of the embossments adjusted, so that the finished workpiece displays little or no distortion to the eye, after having been roll-formed to shape. In this event the expanding effect of the knurling or other cold working is substantially cancelled by the contracting effect of the embossing.
  • embossed pattern is the same irrespective of whether the embossments project from the surface of the workpiece to which knurling is applied or from the opposite surface. In the latter instance the knurled side of the workpiece would display a pattern of recesses or dimples, each corresponding to an embossment on the reverse side of the workpiece.
  • the invention consists in a method of making a cold roll- formed sheet metal article having at least one longitudinally extending cold worked zone characterised by the step of stress relieving said zone by impressing a regular embossed pattern thereon.
  • the longitudinal contraction resulting from the application of the embossed pattern would substantially equal the longitudinal extension resulting from the cold working.
  • Figure 1 is a perspective view of a portion of a sheet metal wall stud according to the invention.
  • Figure 2 is side elevation of a portion of the wall stud of figure 1
  • Figure 3 is a detail sectional view taken on line 3-3 of figure 1 drawn to a larger scale.
  • the illustrated wall stud may be roll-formed from sheet steel coated with zinc or an alloy of aluminium and zinc. It may be generally channel sectioned, and comprise two channel flanges 4, a web 5 interconnecting the flanges and inwardly directed lip flanges 6. In those particulars the stud may be completely conventional.
  • the outer surface of both flanges 4 has a band of knurling extending therealong.
  • the knurling is intended to provide a key for an adhesive whereby a wall cladding panel may be secured to each of the flanges 4.
  • the band of knurling comprises four stripes 7 of a conventional diamond knurl pattern.
  • each embossment 8 overlie the knurling.
  • Each embossment 8 is circular and presents a mound on the outer face of the flange and a corresponding depression in the inner surface thereof, that is to say each mound is hollow.
  • the central parts of each embossment 8 are displaced from the plane of the sheet metal flange.
  • the embossments 8 are arranged in four rows respectively coinciding with the knurling stripes 7.
  • the embossments in neighbouring rows are staggered, so that all together they constitute a regular pattern of embossments evenly distributed over the band of knurling.
  • Both the knurling and the ⁇ embossments may be formed by passing the sheet metal workpiece between appropriately shaped stands of pressure rolls.
  • the roll forming the concave surface of each embossment may be a metal roll with part- spherical mounds projecting from it.
  • the roll contacting the convex side of each embossment may be a tough resilient roll, or a metal roll with shallow holes in register with those mounds.
  • the mounded roll may be screw adjustable in position to provide for adjustment of the extent to which the central parts of the embossments are displaced from the plane of the workpiece.
  • each embossment may be elongated in the transverse direction of the knurled band.
  • each may be an elongated hump extending from edge to edge of the knurling band (with a corresponding groove on the opposite side of the workpiece).
  • the invention may be applied to sheet metal articles generally, and the illustrated wall stud is purely exemplary.
  • the illustrated wall stud is purely exemplary.
  • in respect of reduced stiffening zones it is particularly applicable to roof and wall cladding panels, roll-formed beams, architectral elements and sheet metal structural and frame members, whereas in respect of knurling or the like for enhancing the non-slip character of articles it is particularly applicable to metal planks, stair treads, walkway panels, metal floor tiles, ladder rungs and the surfacing members of all steel materials handling pallets.
