Definitions

  • the object of the present invention is a method for obtaining by rolling metal strips provided with reinforcing reliefs of considerable height, as well as the device for implementing the method, that is to say the cylinders of corresponding appropriate form.
  • the cavities of the cylinder are connected without a sharp angle with the surface of the cylinder, most often by a surface rounded or at least chamfered.
  • the lateral faces of the cavities of the cylinder are inclined surfaces converging towards the bottom of the cavities and not perpendicular to the surface of the cylinder.
  • the inclination (a) "undercut” of the side walls with respect to the perpendiculars to the axis of the cylinder must be limited to an angle of the order of 5 °, this in order to limit the possible development of the metal pushed back into the cavities and allow without too much difficulty, in the subsequent step, the exit from the cavities of the cylinder of the patterns formed in relief on the strip.
  • This shape, slightly flared towards the bottom of the cavities of the rolling rolls, has proved particularly advantageous for the production of sheets ribbed longitudinally in the rolling direction, the cavities then having the form of circular grooves.
  • the high ribs with parallel lateral faces adhere strongly in the cavities or grooves of the cylinder. This phenomenon is further accentuated when the cavities or grooves of the cylinder have "undercut" side faces which generate in the strip ribs with a dovetail cross section, in the axial plane of the cylinders.
  • the traction to be exerted on the laminated strip to detach it from the grooved cylinder may be greater than 40 N / mm2.
  • the overall wrinkling imposed on the strip measured by , S being the initial cross section and s being the final cross section of the product, ie high, generally greater than 60.
  • the method according to the invention therefore consists in machining at least in one of the cylinders cavities or grooves conforming to the description above and in setting them up, in introducing a strip the thickness of which is such that the overall working is greater than 60% with a slight tightening (P) of the rollers, to fix the strip on the winder and to exert a certain traction (F), to gradually and simultaneously increase the speed, the tightening (P) and the traction (F), so that obtain the desired canvas thickness (e).
  • This rolling method also applies to composite strips where the metal core is coated with at least one surface metal layer (such as brazing, cathodic protection or the like) or even to metal-plastic composites.
  • at least one surface metal layer such as brazing, cathodic protection or the like
  • junction of two ribbed strips or sheets thus obtained by any known means (brazing, bonding, etc.) makes it possible to obtain structures resistant to biaxial forces when the ribs are crossed (not parallel).
  • FIG. 1 we see a flat strip (1) 12 mm thick and 950 mm wide, made of annealed quality aluminum 3003, which is laminated between two cylinders (2, 3) to give a strip (4) whose cross section is shown in Figure 3. At the exit of the cylinders, this strip (4) is wound on a winder (5) which exerts a tensile force (F) of the order of 200,000 N.
  • the clamping force (P) between the two cylinders (2, 3) is of the order of 7,000,000 N, that is to say relative to the width of the sheet (1) of the order of 7,000 N / mm.
  • the cylinder (2) comprises a series of parallel peripheral grooves (6) the cross section of which is shown in FIG. 2, while the cylinder (3) comprises, according to the prior art, a series of hollow patterns (7) of shallow depth , regularly arranged on its surface.
  • the ribbed strip (4) has on one side ribs (11) of height (h) substantially equal to the depth (p) of the grooves (6) of width (1 1 ) substantially equal to the width (1) of the grooves (6), in their narrowest part and of pitch (p) equal to the pitch of said grooves (6).
  • the strip (4) has asperities (12) of small thickness, here 0.2 mm corresponding to the patterns (7) of the cylinder (3). These asperities correspond to the prior art.
  • the strip (4) has a thickness (e) of only 1.8 mm.
  • the metal of the strip (1) pushed back by the peripheral surface of the cylinder (2) penetrates substantially to the bottom of the grooves (6) of the cylinder (2) to form ribs (11).
  • the metal flourished in these grooves (6) wider at the bottom than at the inlet, however without filling them completely, as shown by the width (1 2) of the ribs (11) at their upper end.
  • the metal of the strip (1) was forced back by the pressure exerted by the external surface (9) of the cylinder, in the grooves (6). It flourished in these grooves following their divergent lateral faces (10), this up to substantially mid-height of the grooves (6), before being “stretched” at the outlet of the groove.
  • the strip (4) would be wound on the cylinder (2) if it was not pulled by the winder (5) with a force (F) of the order of 200,000 N.
  • F force of the order of 200,000 N.
  • the force (F) allowing the extraction of the sheet (4), causes a sort of lateral rolling of the base of the ribs (11).
  • the lateral rolling of these ribs makes it possible to obtain the desired great heights and proves to be beneficial by compressing the metal.
  • a lateral traction is then carried out on the sheet.
  • the slots (16) widen in the form of substantially hexagonal holes (17), as shown in Figures 6 and 7.
  • the ribs (11) deform in a zig-zag (18).
  • the high and relatively wide ribs give good rigidity to the perforated sheet which has a honeycomb appearance.
  • the slots all have the same length, but one could also obtain perforated and ribbed sheets with slots of different lengths. It is important, however, by good execution, that they are regularly staggered in a horizontal plane.
  • the cylinder (3) has small hollow patterns (7) which give rise to roughness (12).
  • the cylinder (3) could just as easily be smooth or, on the contrary, include deep grooves similar to the grooves (6) of the cylinder (2). With a grooved cylinder (3), we would obtain a sheet (4) with ribs (11) on its two faces.
