Definitions

  • the invention relates to a flanging device according to the preamble of claims 1 and 2.
  • flanging is understood to mean the positive connection of two parts by folding over a flange. In the body shop, an outer and an inner panel in particular are thereby connected to one another.
  • the pre- and finished folding jaws are arranged one above the other on a horizontally movable slide.
  • the folding bed For pre-folding and finishing folding, the folding bed must be moved vertically and the folding jaws horizontally. The folding bed must then have a long adjustment path between the pre-folding and finishing folds and in the respective positions the actual flanging stroke.
  • the invention has for its object to propose a generic device in which the vertical movement of the folding bed is limited to a minimum and the pre and finished folding jaws are brought into position with safe and simple movements.
  • the pre-folding jaw can also be displaced from the outside inwards into the pre-flanging position with the aid of a slide and relative to the slide of the finished folding jaw.
  • the pre-folding jaw is fastened to a swivel flap and can be pivoted from the outside inwards into the pre-flanging position by actuating the swivel flap and that the swivel flap can be locked in the pre-flanging position with the pre-folding jaws attached.
  • the folding jaws for pre-folding and finishing folding can each be moved as independently as possible into the flanging position above the folding bed on their own slides, the travel path of the folding bed can be considerably reduced.
  • the pre-folding jaws and finished folding jaws can be brought into the same flanging position one after the other, so that a large adjustment movement of the folding bed between the pre-folding and finishing folds is not necessary.
  • the folding bed therefore only executes the actual flanging stroke for the pre-folding and finishing folding, and this flanging stroke takes place at one and the same point.
  • the combination of the pivotable pre-folding jaw with the displaceable finished folding jaw is also possible in the alternative embodiment, the combination of the pivotable pre-folding jaw with the displaceable finished folding jaw.
  • a spring-operated hold-down device can be arranged on the upper slide, preferably the slide for pre-folding or on the swivel flap, which holds the two sheets on the surface of the folding bed before the pre-folding and finished folding process begins.
  • the drives for the slide with the finished folding jaw and the pivoting flap on a common console, the console itself being firmly connected to the base frame.
  • the swivel flap can be rotatably mounted on a further bracket via a further swivel joint, which is also firmly connected to the base frame or to the slide.
  • the swivel flap can be locked in the working position in that a locking unit is arranged on the slide for the finished folding, which is brought into the locking position by moving this slide with the existing drive unit.
  • the swing flap and slide can also be coupled to one another in such a way that the forward and finished folding beams can be moved one after the other into the working position with a common drive unit. It has proven to be advantageous to arrange stops on the swivel flap and on the slide, which are brought into contact for locking the pre-folding jaws. For the subsequent finishing folding, the swivel flap can then be swiveled up via a slide guide provided on the slide. Only one drive unit is required for linear movement of the slide, since the pivoting flap is forcibly actuated at the same time as the slide moves.
  • the figures show the outer edge of a folded bed 4 with the outer edges of the body panels 5 and 6 lying thereon.
  • a folding bed 4 is arranged under the entire door. With the flaring stroke, the folding bed 4 with the sheets 5, 6 lying thereon is lifted and for the 2-stage bending of the upstanding flange 7 up to the flat edge area 8 one after the other against the oblique engagement surface 14 of the pre-folding jaw 9 and against the horizontal engagement surface 15 of the finished folding jaw 10 pressed.
  • the lower slide 2 can be moved on a base frame 1 on horizontal guideways 19 for the purpose of folding.
  • the drive 12 for the slide 2 is supported on the frame 1 by the fastening 11.
  • the finished folding jaw 10 is e.g. releasably attached by a screw connection.
  • the upper slide 3 can be moved on the slide 2 for pre-folding on the guideways 20 in the direction of the double arrow shown.
  • the guideways 20 are arranged at an acute angle, preferably at an angle of 25 ° to the guideways 19.
  • the drive 13 for the slide 3 is supported by the attachment 16 on the slide 2.
  • the pre-folding jaw 9 is preferably releasably attached to the slide 3.
  • the upper slide 3 with the pre-folding jaw 9 and the lower slide 2 with the finished folding jaw 10 are in the retracted position.
  • the folding bed 4 with the components 5 and 6 is lowered into the lower end position.
  • the hold-down device 17 fastened to the upper slide 3 is held in the extended lower position by the spring 18 or in some other way.
  • the slide 2 with the finished folding jaw 10 are in the zero position.
  • the slider 3 with the pre-folding jaw 9 moves by approximately 50-60 mm at an angle of 25 ° to the horizontal and can be locked via the toggle lever (not shown) or in some other way.
  • the hold-down device 17 is in the extended position by spring force.
  • the folding bed 4 moves upwards in the flanging stroke, the sheet 6 being fixed in position by the holding-down device 17 by means of spring force.
  • the flange 7 is brought into an approximately 45 ° position by the oblique engagement surface 14 of the pre-folding jaw 9.
  • the folding bed 4 moves downwards by the flanging stroke and the slider 3 returns to the zero position.
  • the slide 3 with the pre-folding jaw 9 is in the zero position.
  • the slide 2 with the finished jaw 10 moves to the stop.
  • the hold-down device 17 is in the extended position by spring force.
  • the folding bed 4 moves upwards by the flanging stroke, the sheet 6 being fixed in position by the hold-down device 17 via the spring force. After the folding process has been completed, the folding bed 4 moves downwards by the flanging stroke and the slides 2 and 3 return to the zero position.
  • the flanging device according to the invention enables a substantial reduction in the vertical movements of the folding bed 4. This is done in that the pre-folding jaws and the finished folding jaws are brought into the same folding position via a hydraulic, pneumatic or electrical drive.
  • the pre-folding jaw 21 is firmly connected to the swivel flap 24.
  • the swivel flap 24 is on the one hand rotatably mounted on the bracket 28 via the joint 26 and on the other hand is pivoted by means of the drive 22.
  • the drive 22 is connected via the joint 25 to the swivel flap 24 and via a further joint to the bracket 23 fixedly attached to the base frame 1.
  • the swivel flap 24 is secured with the aid of the lock 29.
  • the lock 29 arranged on the slide 2 is moved back and forth together with the slide 2 by actuating the drive 12.
  • the console 28 is firmly connected to the base frame 1.
  • slide 2 is provided with an elongated hole in the area of joint 26.
