Definitions

  • the invention relates to a bending machine for folding sheet metal sheets with holding punches for clamping a sheet metal sheet and with at least one drivable bending tool which can be moved around the end of a holding punch serving as a counter tool.
  • the bending tool is pivotally mounted about an axis which lies at least approximately in the bending axis, so that the bending tool always presses vertically against the metal sheet during the bending process, which is bent due to the bending tool attack around the counter tool determining the bending axis .
  • the advantage of these bending machines is that bending angles of up to 150 ° can be achieved. It is disadvantageous, however, that due to the pivoting mounting of the bending tool in the area of the bending axis, it can only be bent in one direction, which necessitates frequent turning of the metal sheets if these metal sheets are to have bends on different sides.
  • this pivotable mounting of the bending tool entails a construction for the support for the support die, which limits the free space in front of the metal sheet insertion, because the support for the support post must be designed to be torsionally rigid. The manipulation of the workpiece is thereby made more difficult.
  • an upper and a lower bending tool are provided, these bending tools being arranged like pliers on the opposite legs of a cross-sectionally C-shaped support and with this support in the vertical direction relative to a pair can be adjusted by counter tools that also serve to clamp the workpiece. Due to the linear drive movement of the bending tools, however, only a bending angle of up to 90 ° can be achieved with such a bending machine, which severely limits the possible design of the workpieces. It is advantageous, however, that it can be bent in two directions, so that there is no need to turn the metal sheets frequently.
  • the invention is therefore based on the object of improving a bending machine of the type described in such a way that, on the one hand, the movement of the bending tools can be adapted in a favorable manner to the required bending of the workpiece and, on the other hand, frequent turning of the workpiece can be avoided.
  • the invention solves this problem in that the bending tool is movably mounted in two directions approximately perpendicular to each other and has separate drives for the two directions of movement.
  • any desired path for the tool can be achieved.
  • only the two drives have to be controlled accordingly. Since the bending tool is thus not bound to a straight or a circular path, all occurring ratios can nisse are taken into account. With a suitable design of the counter tools, two bevels can therefore be carried out in one work step, which is by no means possible with the known bending machines. Because of the unlimited movement and drive possibility of the bending tool, bends in different directions are of course also possible, so that frequent turning of the workpiece can be eliminated.
  • one of the two drives for the bending tool consists of a crank mechanism, on the crank rod carrying the bending tool the other drive engages.
  • the pivotable mounting of the crank rod on the crank pin of the crank mechanism offers the possibility of moving the bending tool transversely to the stroke movement of the crank mechanism by pivoting the crank rod about the crank pin.
  • Elaborate backdrop guides can thus be avoided in a simple manner. If the crank rod carrying the bending tool runs approximately parallel to the clamping plane of the sheet metal plate, a favorable space distribution is ensured because the crank rod, the must be dimensioned accordingly large as a carrier for the bending tool, the arrangement of the support of the counter tools is not in the way. This support therefore does not need to be on the insertion side of the bending machine, so that there is sufficient space for the sheet metal manipulation.
  • crank rod of the drive for the one direction of movement engaging drive for the other direction of movement can also be designed as a crank drive, which allows the two drives to be easily matched to the desired tool movement, in particular for circular path sections.
  • the two crank mechanisms need only be of the same design.
  • both drives as crank drives also offers the possibility of driving both crank drives with the aid of a linkage articulated on a common drive rocker.
  • the linkages can consist of simple connecting links.
  • a common drive rocker separate control of the two drives can be omitted.
  • the common drive of the crank drives however, one is limited to a specific tool path, which can only be changed by changing the mean rotational positions of the crank drives, the cranks of which generally have an angle of rotation less than 180 °, or by changing the transmission ratio of the linkage.
  • the approximately parallel to the clamping plane of the sheet metal crank rod of the one drive two pliers opposite bending tools, the transverse to the clamping plane crank rod of the other drive depending on the mutual distance of the two bending tools is adjustable in length.
  • the length adjustability of the crank rod acting on the bending tools transversely to the clamping plane is necessary in order to be able to position both bending tools on the metal sheet.
  • the other bending tool is located at a distance from the workpiece which corresponds to the mutual distance of the bending tools.
  • crank rod carrying the bending tools must consequently be pivoted, which is carried out in the simplest manner by shortening or lengthening the crank rod of the other drive, which is directed transversely to the clamping plane.
  • the change of use of the two bending tools requires a reversal of the direction of movement of one of the two drives with regard to the tool path.
  • the two drives are each connected via a linkage to a common drive arm, such a reversal of movement can be achieved in that the articulation point of one of the two linkages on the drive arm is adjustable between two positions opposite one another with respect to the pivot axis of the drive arm. Since two points that are diametrically positioned with respect to an axis of rotation perform opposite movements during a rotation adjustment, a corresponding adjustment of the linkage point of the linkage makes the direction of movement of the linkage above this linkage connected crank drive vice versa.
  • the bending machine shown consists essentially of a frame 1 which has two bending tools 3a and 3b, which are arranged on a C-shaped support 2, are opposite one another in the manner of pliers, and two holding punches 4a and 4b, which serve as counter tools for the bending tools 3a and 3b.
  • the sheet metal plate 5 to be bent is clamped between the holding punches 4a and 4b, the holding punches 4a and 4b being supported on rigid and torsionally rigid box girders 6, of which the upper one can be raised and lowered in a manner not shown.
  • the C-shaped carrier 2 for the bending tools 3a and 3b is carried by a crank rod 7 of a crank mechanism 8, the crankshaft 9 of which is mounted in the frame 1. Via this crank mechanism 8, the bending tools 3a and 3b can be parallel to the clamping plane of the Sheet 5 are moved.
  • a further crank mechanism 10 is provided, the crankshaft 11 of which is mounted in the frame 1 and the crank rod 12 extending transversely to the clamping plane of the sheet metal plate 5 is articulated on the crank rod 7 of the crank mechanism 8.
  • the length of the crank rod 12 of the crank mechanism 10 is adjustable, which is achieved with the aid of a cylinder 13 according to the exemplary embodiment.
  • the upper bending tool 3a is used, as shown in FIGS. 1, 3 and 4, while for the use of the lower bending tool 3b the cylinder 13 according to FIGS. 5 and 6 has to be retracted.
  • each of the two bending tools can be moved along a circular path around the bending axis 14, as is shown for the upper bending tool 3a in FIG. 2. From the fully drawn starting position, the bending tool 3a reaches its end position, indicated by dash-dotted lines, along the movement path 15, the sheet metal plate 5 being bent out of the clamping plane around the holding punch 4b serving as a counter-tool.
  • the metal sheet 5 to be bent can be bent both upwards and downwards, so that a largely unlimited design possibility for the workpiece is ensured without having to turn the workpiece frequently.
  • the movement path 15 can be changed in shape and size in accordance with the requirements determined by the shape of the workpiece to be produced. For this reason, different bending tools and counter tools can advantageously be used.
  • a common drive rocker 16 is provided for driving the crank drives 8 and 10 and can be driven via a toothed segment 17 and a pinion 18 meshing with the toothed segment 17.
  • the crank mechanisms 8 and 10 are connected to this drive rocker 16 via a linkage 19 or 20, which in the simplest case consists of a connecting link. If the drive rocker 16 is pivoted about its axis of rotation 21 from the position shown in FIG. 3 into the position according to FIG. 4, the crank drives 8 and 10 are adjusted accordingly via the linkages 19 and 20, the tool 3a being used being moved through the crank mechanism 8 is pushed forward against the holding plungers 4a and 4b and at the same time is pressed downward via the crank mechanism 10, which results in a tool movement, as shown in FIG. 2 by the movement path 15. After this working stroke, the drive rocker 21 returns to its starting position, which results in the withdrawal of the bending tool 3a.
  • the cylinder 13 must first be acted upon in order to pivot the crank arm 7 of the crank mechanism 8 around the crank pin 22 in the direction of the bending tool 3b until the bending tool 3b assumes the position shown in FIG. 5 .
  • the lower bending tool 3b since bending is in opposite directions, the lower bending tool 3b must be pushed upward via the piston drive 10, which requires the direction of rotation of the crank drive 10 to be reversed.
  • this is achieved by displacing the articulation point 23 of the linkage 20 on the drive rocker 16, for which purpose a cylinder 24 is arranged on the drive rocker 16, via the piston rod of which the articulation point 23 is adjusted, while the articulation point 25 of the linkage 19 the drive arm remains unchanged.
  • the lower bending tool 3b must also be advanced against the holding punches 4a and 4b in order to achieve a correspondingly large bending angle.
  • crankshaft 11 of the crank mechanism 10 Since, according to the adjustment of the articulation point 23 of the linkage 20 on the opposite side of the drive rocker with respect to the pivot axis 21, the crankshaft 11 of the crank mechanism 10 is driven in opposite directions, the crank rod 7 is also pivoted in opposite directions about its crank pin 22, so that the lower bending tool 3b at the Drive movement engages behind the upper holding punch 4a, as indicated in Fig. 6.
  • the metal sheet 5 can thus be bent downwards or upwards in the same way.
  • the adjustment paths can be changed via the angle of rotation of the crank mechanisms 8 and 10. This is possible, for example, by changing the swivel angle of the drive rocker 16 or by adjusting the articulation points of the linkages 19, 20 on the crank drives or on the rocker 16.
