Definitions

  • the invention relates to a device for automating the process of bending workpieces of a metal sheet for using in a bending press.
  • Manipulators are used for this purpose, including industrial robots, which enable bending of a workpiece in different planes. After bending in one plane, a robot rotates the workpiece in different planes by means of grippers arranged on the boom and then transfers it to the bending machine.
  • a solution of this type is used in devices for bending edges of metal sheets produced by different manufacturers of press brakes and industrial robots, such as: Trumpf, Amada, Kuka, and Motoman.
  • One disadvantage of that solution is a slow bending process and high price.
  • Salvagnini Italia S.p.a Another approach to the problem of bending processes was proposed by Salvagnini Italia S.p.a.
  • One of the devices marketed by the company is an automated bending line for workpieces of metal sheets, equipped with a linear manipulator.
  • the manipulator after folding one edge, withdraws a workpiece from the machine and, in order to bend successive edge, it rotates and reintroduces the workpiece into the bending machine.
  • the workpiece handling is carried out in one plane and bending of the workpiece edge entails the necessity to equip the bending machine with appropriate tools.
  • the disadvantage of this solution is a limited thickness of bent workpieces to 2.5 mm and a very high price of the device.
  • the present Applicant has developed a device for automating the process of bending workpieces of a metal sheet for a bending press, which is the subject matter of the Polish patent application No. P.400138 , and which allows bending several edges of the workpiece in different planes, without the necessity to move the workpiece away from the press in order to change its position.
  • the device comprises:
  • the device is fixed to the bending press in one fixed position.
  • the purpose of the present invention is to further improve this known device by providing it with additional features and advantages.
  • the device comprises guides for attaching the device to the press along its entire length and means formed in the supporting frame for slidably mounting of the supporting frame on the guides and it comprises a driving device mounted on the supporting frame for moving the support frame along the guides.
  • Fig. 1 shows schematically the construction of the device for automating the process of bending workpieces of metal sheet for bending press in a front and side perspective view.
  • front, rear, bottom, top, right, left relate to the device shown in the accompanying drawing, as it is fixed relative to the bending press.
  • the device 1 for automating the process of bending workpieces of metal sheet for bending press comprises a supporting frame 2 having a rear side for attaching the device 1 to the press (not shown) and an opposite front side.
  • the supporting frame 2 comprises two mutually parallel side walls 3, which are connected to one another by at least one crosspiece 4, in the example shown by means of an upper crosspiece and lower crosspiece.
  • the device 1 comprises guides 6a, 6b for attaching the device 1 to the press along its entire length and means formed in the supporting frame 2 for a slidable mounting of the supporting frame 2 on the guides 6a, 6b.
  • a driving device 7 is mounted on the supporting frame 2 for moving the supporting frame 2 along the guides 6a, 6b in the X direction along the length of the press (to the left and right in the drawing).
  • the driving device 7 is attached to the lower crosspiece 4.
  • the guides 6a, 6b comprise an upper guide 6a and a lower guide 6b parallel to it.
  • the lower guide 6b is a toothed bar
  • the driving device 7 is coupled with the toothed bar via the gear wheel 5 for moving the supporting frame 2 in the X direction along the length of the press.
  • the top plate 8 is connected to a top plate driving device 11, which ensures the movement of the top plate 8 along the guides 10, whereby the top plate 8 can be displaced upwards as shown by the arrow K.
  • An axis of rotation of the top plate 8 is arranged in the bending line of the metal sheet.
  • a table 12 is arranged in the cut-out 9 of the top plate 8, the table 12 is mounted on cross-guides 13, connected to the top plate 8 and extending along the side walls 3 of the supporting frame 2.
  • the cross-guides 13 are perpendicular to the press at a rest condition.
  • the cut-out 9 in the top plate 8 has a rectangular shape.
  • the table 12 has a rectangular shape and dimensions smaller than the dimensions of the cut-out 9 in the top plate 8.
  • the table 12 is connected to a table driving device (not shown) moving the table 12 in the Y direction on cross-guides 13.
  • the workpiece to be bent is attached to the device by means of fasteners known in the art, for example suction cups or magnetic elements that are arranged in a rotatable plate 14.
  • All the above mentioned driving devices that is, drives of the supporting frame 2, the top plate 8, the table 12 and the rotatable plate 14, carrying out the above described movements of the device are connected to and controlled by an external control device connected to the control desk.
