Definitions

  • the present invention relates to a method of manufacturing ribbed panels, intended to obtain at the end of the ribs a practically straight edge of the panel, allowing the sealed assembly by welding of the panel with a support frame.
  • Such a panel can be produced in different ways, the most common of which are folding and stamping.
  • Bending consists of making open ribs at their two ends by pressing a flat metal profile between a punch and a die carried by a press brake so as not to stretch the metal, which has the enormous advantage of requiring a extremely low press brake power.
  • Stamping consists in pressing the profile between a punch and a die carried by a stamping press so as to produce the closed ribs by a single digging operation with stretching of the metal.
  • This process has the advantage of making it possible to produce a perfectly sealed assembly by a quick operation; on the other hand, the power to be used is considerable compared to that required for folding, so this method requires high power manufacturing means, not only very expensive but also more difficult to obtain on the market.
  • a panel with open ribs in the shape of a straight U is firstly folded, and, with special tools, the ends are crushed or folded so as to flatten the edges of the panel.
  • Another known method consists in pressing the panel between a punch and a die whose complementary profiles ensure the formation of a stamped rib by creep of the metal and connecting to the general surface of the profile, on the edges thereof, by slopes comprising several plies absorbing the excess of stamped material, and therefore forming necking ribs.
  • This method has the disadvantage of still making use of the actual stamping for the formation of the necking ribs, and therefore of requiring a press power substantially greater than that required for a simple folding.
  • the method of manufacturing panels with closed ribs according to the invention does not have the drawbacks of all the methods known hitherto. It is characterized in that it consists in pressing the sheet to be profiled between a punch and a die whose complementary profiles ensure for each rib a constant development as well as of the ends of each rib with quasi-rectilinear edges by absorption of the difference between said developed and its projection on the horizontal plane by one or more folds whose folds are almost contiguous on the edges of the panel, and perpendicular to the plane of said panel.
  • the constant press can over the entire length of each rib, apart from its two ends, be in different known geometric forms (trapezoid, rectangle, half-circumference, etc.).
  • each rib 2 of the panel 1 has a central portion 3 of regular section and which is connected at each end with the straight edge 4 of the panel by means of a connection profile 5 forming a slope and furnished with two corrugations (6,7) so that the rib opens in a quasi-rectilinear manner, with the clearances of the corrugations 6 and 7 near, on the edge 4 of the panel.
  • the developed of the two profiles 2 and 5 are always equal along these, so that the panel of the invention is produced by simple folding and therefore at using very low press brake power.
  • the variant of the method of the invention resulting in the form of rib shown in FIG. 4 consists, after obtaining, using the above defined method, ribs as shown diagrammatically in FIG. 1, to carry out an additional operation consisting of, for example using a special tool fitted with one or more pliers, to join the ends of the corrugations 6 and 7 by pressing them at their ends so as to remove the play e.
