Definitions

  • the invention relates to a device for folding sheet metal, in particular body panels in the automotive industry, in one Base frame a ram with a folding bed on top of the sheets to be folded presses against the stationary folding tools.
  • the invention is therefore based on the task of driving the plunger in to improve the way that the construction is simplified.
  • the proposal according to the invention is used as a tappet drive
  • Air cushions are used to increase the working stroke and the force to fold the To be able to apply sheets pneumatically.
  • the air cushion is between Base frame and ram arranged. It can in particular in the Base frame and at least the entire base of the ram take in.
  • the force is advantageously above a chamfer arranged on the circumference of the ram is initiated, so that this is greatly simplified in its outer shape and dimensions.
  • the ram needs only small stiffening ribs, since the folding force is no longer from the center to the Edge area of the plunger must be initiated.
  • it can Compressed air cushion in a standardized substructure of the base frame of the Folding device can be accommodated.
  • the air cushion is not only through the embedding in the base frame, but also fixed via the plunger and over several circumferential guide rails in the direction of movement of the ram in the base frame.
  • Adjustment of the fold adjustable stops in appropriate Recesses of the base frame can be arranged.
  • To connect one Compressed air hose to the compressed air cushion can also be in the base plate a corresponding passage opening of the plunger, so that the compressed air hose not through the base frame, but from above the preferably centrally arranged passage opening is fed.
  • Fig. 1 the compressed air cushion 3 is shown, which is in the base frame 2 and which is fixed to the plunger 1 with the compressed air hose 5.
  • the plunger 1 is over guided several short guide rails 8 in the base frame 2.
  • the stops 4 serve to limit the fold stroke and can be used to adjust the fold be tuned or adjusted.
  • the force is about one at the scope of the Ram 1 arranged bend 10 initiated.
  • Fig. 1.2 is an embodiment according to the prior art for explanation Hydraulic cylinder 6 shown. Here are to guide the plunger 11 in Base frame 12 long guide strips 8 used. To limit the Different folding positions are also pins 7 and Tie rod 9 applied.
