Definitions

  • the present invention relates to crimping systems, and more specifically to roller crimping systems.
  • Known crimping systems are used in order to join a first metal plate and a second metal plate by folding over a flange on one of them.
  • said folding is performed by at least a roller, said roller being moved all the way along the edge of said flange by means of a crimping device.
  • the first metal plate is disposed on a work bench or cradle support, the second metal plate being disposed on said first metal plate.
  • the first metal plate comprises a flange all the way along its edge, the roller exerting a pressure on said flange all the way along said edge, with the result that said flange is folded over, being disposed on said second metal plate, said first metal plate and said second metal plate thus being joined together.
  • the crimping device moves said roller all the way along said edge, the folding over of said flange being performed by said roller moving over it successively.
  • US2005086989 and US2005229666 disclose a crimping system in which only one roller may be applied against the flange of said metal plate at any one time.
  • Patent EP1097759A1 discloses a crimping system in which two rollers act simultaneously on the flange to be folded over, one roller following the path of the preceding roller. Thus, while a first roller exerts pressure on said flange folding it over at a certain angle, the roller that follows said first roller folds said flange over at another certain angle, thereby reducing the time required in order to join the metal plates together.
  • Said crimping system comprises two robot arms, each robot arm comprising a roller. Each robot arm is controlled independently, therefore enabling control of the movement of each roller all the way along said edge independently. Thus, to perform the folding over of said flange the movement of said robot arms is controlled independently.
  • the roller crimping system comprises a work bench or cradle support upon which a first metal plate is disposed, a second metal plate being disposed on said first metal plate, said metal plates being joined together by means of a crimping process.
  • Said first metal plate comprises a flange that extends all the way along its edge, said flange being folded over in order to join said metal plates together by means of said crimping process, said flange being disposed on said second metal plate.
  • Said crimping system also comprises a first roller and a second roller that are moved in a folding direction all the way along the edge of the first metal plate in order to fold said flange over, said rollers acting simultaneously on said flange. Said first roller folds said flange over to a certain intermediate angle, said second roller folding said flange over to a folding angle.
  • the rollers are moved by means of a crimping device, said crimping device comprising a single robot arm that has a crimping tool on one of its ends.
  • Said crimping tool comprises the first roller and the second roller, only one robot arm having to be controlled in order to fold over the flange of the first metal plate
  • the crimping tool also comprises a platform, said rollers being capable of moving, in a independent way, linearly in respect of said platform in a direction of movement perpendicular to the direction of folding by means of a first actuator and a second actuator respectively.
  • FIG 1 shows an embodiment of the roller crimping system of the invention.
  • Said crimping system comprises a work bench or cradle support 4 upon which a first metal plate 30 is disposed, a second metal plate 31 being disposed on said first metal plate 30 and said metal plates 30 and 31 being joined together by means of a crimping process.
  • Said first metal plate 30 comprises a flange 30' that extends all the way along its edge, said flange 30' being folded over in order to join said first metal plate 30 to said second metal plate 31, said flange 30' being disposed on said second metal plate 31.
  • Figures 2 and 3 show the arrangement of said metal plates 30 and 31 before and after the crimping process respectively.
  • the crimping system of the invention also comprises at least a first roller 21 and a second roller 22.
  • Said rollers 21 and 22 are moved in a direction of folding A all the way along the edge of the first metal plate 30 in order to fold the flange 30' over.
  • Said second roller 22 follows the path of said first roller 21, said rollers 21 and 22 being capable of acting simultaneously on said flange 30'.
  • said first roller 21 folds said flange 30' over to a certain intermediate angle ⁇ 1 as shown in Figure 4
  • said second roller 22 folds said flange 30' over from said intermediate angle ⁇ 1 to a folding angle ⁇ 2 as shown in Figure 5 .
  • said angles ⁇ 1 and ⁇ 2 may be, for example, 30° and 60° respectively, although they may also be, for example, 45° and 90°, thereby completing the crimping process.
  • the rollers 21 and 22 are moved by means of a crimping device.
  • Said crimping device comprises a single robot arm 1 that has a crimping tool 2, shown in Figures 6 and 7 , on one of its ends, said crimping tool 2 being joined to said robot arm 1 by means of a joining piece 27.
  • Said crimping tool 2 comprises said rollers 21 and 22 and a platform 7.
  • Said rollers 21 and 22 are capable of moving, in a independent way, linearly in respect of said platform 7 in a direction of movement B perpendicular to the direction of folding A by means of a first actuator 8 and a second actuator 9 respectively.

  • said rollers 21 and 22 act simultaneously on the flange 30' of the first metal plate 30, folding said flange 30' over to the folding angle ⁇ 2 in a single passing movement.
  • the crimping system also comprises a third roller 23 joined to the second longitudinal axis 11 on the opposite end to that of the second roller 22 and a fourth roller 24 joined to the first longitudinal axis 10 on the opposite end to that of the first roller 21, although said rollers 23 and 24 may also be joined to said first longitudinal axis 10 and to said second longitudinal axis 11 respectively.
  • the rollers 21 and 22 fold the flange 30' of the first metal plate 30 over to a folding angle ⁇ 2 of 60°, said third and fourth roller 23 and 24 being used to fold said flange 30' over to a final angle of 90°, thereby completing the crimping process.
