Definitions

  • the invention relates to a swivel bending press for folding and deforming metal sheets, with a C-frame, a fixed lower beam and a height-movable upper beam as well as a bending beam that can be pivoted about the horizontal folding axis.
  • the sheet In the known swivel bending machines, the sheet is held by two cheeks and angled by a swivel bending cheek. In terms of construction, however, the folding machines available on the market are limited to a processing length of around 4 m.
  • the known bending presses mechanically or hydraulically driven, have press beams, which are preferably guided on C-shaped machine stands and on which prism tools are attached to achieve different shapes and bending angles.
  • press beams which are preferably guided on C-shaped machine stands and on which prism tools are attached to achieve different shapes and bending angles.
  • the metal sheet and swung need to prevent this special tools are used, but this is technically only useful mm for sheet thicknesses of less than third
  • the object of the invention is to provide a swivel bending press with which very long metal sheets can be bent and deformed in their edge regions in a simple and precise manner.
  • the swivel bending press according to the invention shows, in a C-frame, a bending beam which can be swiveled by swivel segments around the folding axis, the design, arrangement and swiveling of which make it possible to fold the edge areas of very long and large sheet metal panels.
  • This bending beam can be used to fold metal sheets with sheet thicknesses of 5 to 7 mm up to a length of approximately 14 m.
  • the maximum bending depth of the metal sheets is determined by the shape and size of the C opening in the C frame of the press.
  • the swivel segments holding the bending beam are each pivoted in parallel by their own or common drive, which results in a precise bending of the metal sheets.
  • the swivel bending press according to the invention enables several identical presses to be strung together to form a structural unit.
  • the essence of the invention is the fixed machine stand made of the C-brackets with the link guides in the C for the bending beam and the drive of the bending beam through the toothed segments via gear transmissions to the hydraulic or electric motor, so that the bending beam is stably supported in a simple design over a large swivel range is and allows in a simple and precise way a folding of very long and large sheet metal sheets, even with thicker sheet thicknesses.
