Definitions

  • the invention relates to a profiling head equipped with anti-bending means for forming, by rolling, plates of sheet metal or equivalent having a certain profile, for example U, V or other.
  • the invention also relates to machines equipped with such profiling heads.
  • a profiling line of a profiling machine the sheet is progressively formed by passing through profiling heads equipped with rolling cassettes.
  • the profiling machines comprise one or more profiling lines until the desired profile is reached.
  • the sheet is unrolled from a reel, formed by passing through the rolls of rolling profiling heads, then collected on an output conveyor equipped with plate cutting shears and finally stacked.
  • bending machines can be provided for bending the shaped sheet metal plates. Electronic equipment for controlling the profiling lines is also provided.
  • Each rolling cassette of the profiling heads comprises a set of two parallel shafts on which rollers and spacers are mounted.
  • the sheet is formed by passing between these rolling means respectively having a complementary profile, the two shafts being adjusted in distance on vertical uprights according to the sheet thicknesses.
  • a support frame for the shafts comprising the vertical uprights and a base is provided.
  • the current trend is to substantially reduce the diameter of the mounting shafts and rollers.
  • the use of such shafts cause problems of bending and adjustment of the trees due to their deformation due to the dynamic stresses generated by the weight of the sheets and their advancement in the profiling lines. Adjustment can then be achieved by clamping the rollers of the rollers, which causes in time a digging effect of the rings by the work of the shaft.
  • the trees are never perfectly cylindrical and their runout may, in rotation, cause their ejection.
  • the invention provides to make the adjustment of all shafts and forming means integral and to provide bending adaptation means.
  • the subject of the invention is a profiling head comprising at least one roller forming cassette comprising a set of two parallel shafts on which rollers separated by spacers are mounted to form a rolling tool, and a frame comprising vertical uprights for supporting the shafts and a base for fixing these uprights, which uprights are provided with means for vertical adjustment of the shafts.
  • the profiling head also comprises tool alignment adjustment elements, mounted laterally on each shaft in connection with at least one vertical upright, and anti-bending adjustment elements mounted substantially in the central position of each connected shaft. with the base and / or a control beam in the case where such a control beam is mounted on the vertical uprights of the frame parallel to the shafts.
  • the invention also relates to a profiling machine comprising a sheet metal storage coil, several progressive profiling heads as defined above, an output conveyor equipped with plate cutting shears profiled sheet, a tray of stacking of the plates and electronic equipment for driving profiling lines formed by each profiled sheet.
  • bending machines can be provided for bending the shaped sheet metal plates.
  • the profiling head 1 view in main section is equipped with a rolling cassette 2 having a set of two parallel shafts 20 and 30.
  • Rollers 201 to 217 are mounted on the shaft 20 and the rollers 301 to 310 are mounted on the shaft 30. Most of these rollers are mounted on bearings 3. Spacers 200 and 300 are mounted directly on the shafts 20 and 30 to wedge the rollers of one shaft on the corresponding rollers of the other shaft. The rollers and spacers form the rolling tool.
  • the forming sheet is inserted between the rollers thus positioned opposite and respectively having a complementary profile.
  • the two shafts being adjusted in distance on lateral uprights 41 and 51 depending on the desired gap between the rollers of the trees located opposite for a given thickness of sheet to be formed.
  • a tree support frame comprises the vertical uprights 41, 51 and a base 60 on which these uprights are fixed with parts 42, 43 and 52, 53 forming vices.
  • the shafts 20 and 30 are mounted parallel to the uprights 41 and 51 by means of lateral adjustment elements, respectively 61 and 71, mounted on the shafts with the aid of bearings 3 and fixed to these uprights.
  • the amounts 41 and 51 are provided with stops 44 and 54 for vertical adjustment of the shafts, whose position is locked by nuts 45, 46 and 55, 56.
  • the mounting shafts and rollers have a reduced diameter compared to those conventionally used.
  • the diameter of the shafts is 60 mm, whereas a conventional diameter is 100 mm.
  • the lateral adjusting elements 71 fixed to the upright 51 comprise tooling alignment means by centering, as detailed below, while the adjustment elements 61 mounted on the other upright 41 do not include a centering system. .
  • an adjusting beam 80 is mounted on the vertical uprights, using connectors 81 and adjusting nuts 82, parallel to the mounting shafts 20 and 30.
  • Anti-bending adjustment elements 90 and 91 are mounted substantially in the central position of each shaft, respectively in connection with the base 60 and the adjusting beam 80 via the rods 4 and 5.
  • the rod 4 has an adjustable height through a set 6 nut / lock nut mounted on a threaded end 4a of this rod 4. The rod is inserted into the non-threaded orifice 7a of a nozzle 7.
  • the other rod 5 is fixedly mounted on the adjustment beam 80 to the using means known to those skilled in the art.
  • the lateral adjustment elements 61, 71 and anti-flexion 90, 91 are mounted on bearings 3 and 3a, and automatically adjust to the vertical adjustment made on the stops 44 and 54.
  • FIGS. 2a, 2b and 2c illustrate a side view and sectional views of FIG. 1 concentrated on an alignment alignment element 71 of the tooling.
  • an alignment alignment element 71 of the tooling comprises two centering bolts with threaded screws 72 and 73.
  • the bolts are mounted on two flanges 74 and 75, disposed externally on two walls 57 and 58 of the upright 51, to pass through the walls 57 and 58.
  • FIG. 3a an anti-bending adjustment element is illustrated in FIG. 3a.
  • Such an element 90 comprises a conical ring 92a slotted longitudinally along the axis X'X of the shaft 20.
  • the ring has a thickness sufficient to serve as a spacer.
  • On this ring 92a is mounted a bearing 3a whose inner bearing 30 has the same taper as that of the ring 92a.
  • the relative position of the bearing 3a on the ring is set laterally by relative movement (arrow F) of this bearing along the conical ring 92a by means of a nut 32 in connection with a threaded portion 93 of the split ring.
  • Such a displacement simultaneously induces a constriction or loosening of this ring.
  • FIG. 3b Another anti-flexion element 91 is illustrated in FIG. 3b.
  • This element consists of a split ring 92b of the same type as the ring 92a and a bearing 3a conical inner bearing 30, identical to the bearing associated with the ring 92a.
  • a lateral displacement causes the rolling of the bearing 3a on the ring 92b whose diameter remains constant by increasing or decreasing the opening of the slot of the ring. The displacement is provided by the roller 305 which bears against the bearing 3a.
  • FIG. 4 illustrates, in cross-section along a variable plane AA of FIG. 1, the two anti-bending adjustment elements 90 and 91 of FIGS. 3a and 3b.
  • the figure highlights the use of external bearings partial 94a, 94b formed of a cylinder section disposed opposite the connecting rod 4 to the base 60 or the rod 5 connecting to the beam 80.
  • the ends of the rods 4 and 5 are respectively fixed in the bearings Partials 94a and 94b.
  • This reduction in bearing length advantageous in terms of cost, is justified by the fact that only an outer bearing portion is useful for adjustment.
  • the inner bearings 30 remain complete.
