Definitions

  • the present invention relates to a roll forming machine for manufacturing profiles, in particular metal.
  • the object of the present invention is to remedy these drawbacks.
  • This object of the invention is achieved with a profiling machine of the type which can operate with different sets of pairs of profiling heads according to the type of profile to be manufactured, remarkable in that said pairs of heads are mounted on carriages which can slide in the two direction of a direction transverse to the profiling line, so that one game can be replaced by another with the minimum of manipulations.
  • said profiling machine comprises carriages supporting a plurality of pairs of profiling heads belonging to separate sets
  • said profiling machine comprises distinct groups of carriages supporting pairs of profiling heads belonging to distinct sets
  • said profiling machine comprises on the one hand first and second sets of pairs of profiling heads mounted side by side on a first group of carriages, and on the other hand third and fourth sets of pairs of profiling heads mounted side by side on a second group of carriages independent of said first group, said profiling machine comprises at least one double-acting cylinder for moving each of said carriages,
  • - Said profiling machine comprises two double-acting cylinders mounted in opposition to move each of said carriages, so as to selectively place the carriages of said first group in one of the following three positions: inactive heads, first set of active heads, second set of heads active, and to selectively place the carriages of said second group in one of the following three positions: inactive heads, third active head set, fourth active head set,
  • one of said two jacks is longer than the other, so as to take into account the size of a drive motor for the pairs of profiling heads supported by the corresponding carriage,
  • said profiling machine comprises means to prevent it from starting up as long as said carriages have not reached an alignment allowing the use of one of said games
  • - Said means comprise a plurality of holes formed in said carriages, arranged so as to be aligned when said alignment is reached, and a laser beam arranged so as to pass through all of said holes when said alignment is reached
  • said carriages are mounted on rollers rolling on rails, and said rails include recesses arranged so as to index the positions of said carriages corresponding to the use of each of said j eu,
  • - Said profiling machine comprises gantries provided with wedges adapted to support said carriages when said rollers are in said recesses.
  • FIG. 1 is a perspective view of a part of the roll forming machine according to the invention
  • FIGS. lat and 1b are enlargements of details of FIG. 1,
  • FIG. 2 is a perspective view of a carriage of this profiling machine supporting first and second pairs of profiling heads belonging respectively to separate sets,
  • FIG. 2a is an enlargement of a detail of FIG. 2,
  • FIG. 3 is a bottom view of part of the profiling machine of Figure 1
  • - Figures 4a, 4b, 4c are schematic views showing the three positions that can occupy each of the carriages.
  • the roll forming machine 1 comprises a plurality of carriages Ci arranged transversely to the profiling line shown by arrow F.
  • profiling line the person skilled in the art will understand here that the path intended to be taken by each sheet to be profiled moving inside the profiling machine 1, between its inlet 3 and its outlet 5.
  • each carriage Ci comprises first Pli and second P2i pairs of profiling heads arranged side by side, that is to say in alignment one of the other according to direction T.
  • profiling head is understood here to mean a plurality of preferably metallic discs Di supported by the same axis Ai, each pair of heads Pli, P2i therefore being formed of two such pluralities of discs Di, Dj mounted on two parallel axes Ai, Aj. Note that these pairs of heads have not been shown in Figure 1, and this for the sake of clarity.
  • the set of pairs Pli with i even, Pli with i odd, P2i with i even and P2i with i odd respectively define four sets of pairs of heads each making it possible to obtain profiles of a determined type.
  • set of pairs of heads designate the set of pairs of heads placed one after the other in the direction F (see Figure 1), to obtain a predetermined type of profiles.
  • Each carriage Ci further comprises a geared motor assembly Mi for driving the two pairs of heads Pli and P2i, this assembly being supplied by suitable electrical connections not shown.
  • the disks Di, Dj of each pair of heads rotate in opposite directions in order to gradually give the desired shape to the sheet plates which supply the profiling machine 1.
  • Each carriage Ci comprises rollers Ri adapted to allow this carriage to slide on corresponding rails RAi (see FIG. 1).
  • the rails RAi include hollows CRi capable of receiving the rollers Ri.
  • the profiling path is delimited by first ni and second 112 gantries.
  • a plurality of shims CAi are fixed on these gantries, these shims being capable of cooperating with shoulders Ei (see the detail view 2a) formed on each of the carriages Ci when the rollers Ri are found in the CRi hollows.
  • double-acting cylinders Vi are interposed between each carriage Ci and a fixed support S connected to the ground.
  • each carriage Ci is connected to the fixed support S by means of two double-acting cylinders Vli and V2i having a common rod Ti.
  • the jack Vli which is connected to the carriage Ci is preferably longer than the jack V2i connected to the fixed support S.
  • each carriage Ci can occupy three different positions, corresponding to the different situations of the cylinders Vli and V2i.
  • the position shown in Figure 4a corresponds to the situation where the cylinders Vli and V2i are both elongated.
  • the profiling machine 1 comprises means for preventing it from starting up until the carriages Ci have not reached an alignment allowing the use of the set of pairs of heads desired.
  • these means may include holes TRi formed in each carriage Ci, and a laser beam RL arranged so as to pass through the holes TRi of all the carriages Ci when said alignment is reached, and thus illuminating a photocell CP triggering the authorization to start the profiling machine.
  • the profiling machine 1 makes it possible to manufacture four different types of profiles simply by suitably sliding the carriages Ci before manufacture. It is therefore no longer necessary, as in the prior art, to lift each pair of profiling heads by means of an overhead crane to replace it with another, which allows on the one hand to considerably reduce the time of shutdown of the roll forming machine, and on the other hand to eliminate all risks for personnel linked to lifting operations.
  • the hollows CRi formed in the rails RAi make it possible to index the different possible positions of the carriages Ci, so again here to improve the accuracy of the transverse positioning of the pairs of heads Pli, P2i.
  • the wedges CAi allow, by cooperating with the shoulders Ei (see FIGS. 1b and 2a), to immobilize completely each carriage Ci once the rollers
  • the profiling machine according to the invention could comprise only a single group of carriages each supporting a plurality of pairs of profiling heads belonging to separate sets.
  • the profiling machine could comprise separate groups of carriages each supporting only one pair of profiling heads belonging to a given set.
