Definitions

  • the invention relates to a Häantschmati with a stop and / or gripping and / or measuring element, as set forth in claim 1.
  • DE 697 22 935 T2 discloses a back stop unit which is constructed on the basis of a scissors lift unit.
  • two horizontally aligned stop fingers arranged on a common, running in the direction parallel to the sheet bending line, guide rail, and thereby individually displaceable in this direction.
  • This common guide rail is mounted on the scissor lift units via two rods guided on the upper legs of the scissor lift unit.
  • Scissor lift unit with a common guide rod, on which the guide rail is mounted ensures that the guide rail and the attached stop fingers can always maintain their horizontal orientation, even with a change in the positioning height, and not arbitrary in terms of their horizontal orientation can be moved.
  • On the underside of the two legs of the scissor lift unit two guide elements are mounted, which can be moved in horizontal guide rails along the longitudinal direction of the guide rails in order to achieve a height adjustment of the stop fingers.
  • the described guide rails are partially formed as spindles in order to achieve the desired height adjustment via an adjustment of the guide elements relative to each other.
  • the arrangement of the Schuanschlagtechnik described takes place directly on the machine frame of a bending machine.
  • this back stop unit which is designed as a scissor lift, is thus limited to the half of the scissor lift unit facing the bending press, since the stop finger can not assume a position in which it can be positioned on the side of the scissor lift unit facing away from the press brake.
  • a disadvantage of known designs, which are driven by linear drives, is that there is a relatively high center of gravity of the entire backgauge unit.
  • the present invention has for its object to improve a Häanschlagiser for connection to a sheet metal processing machine, in particular a bending machine such that it is designed advantageous in terms of their moving masses, and also makes the best use of the available space to a large variation to achieve positioning possibilities.
  • This object of the invention is solved by the features according to claim 1.
  • the free positioning of the support arm by means of a linear displacement of a support arm and the rotary shear joint required for this purpose are important, as opposed to the possibility of an inverse position in which the support arm, which receives a stop element, is not turned towards the bending press , but in the, facing away from the bending press side shows, and thus makes the best use of the available space.
  • a back stop unit is formed with a stop and / or gripping and / or measuring element, which is arranged by means of a rotary joint on an adjustable support arm.
  • This backgauge unit serves to position a sheet to be processed on a bending press.
  • the support arm is connected by means of a further rotary joint with a guide element which engages in a guide rail.
  • a support arm is present, which is connected via a hinge with the support arm and a rigid connection with another guide element.
  • This further guide tion element engages as the first guide element of the support arm in the guide rail.
  • The, the support arm and the support arm connecting, joint is designed as a rotary sliding joint.
  • An advantage of the design according to the invention is that the control of their position via drives, which are arranged in the underlying guide rail can be done by the formation of the Stromanschlagiser means of two articulated arms.
  • This arrangement of the drives ensures that no large moving masses are arranged at a great distance from the machine frame, and thus to the guide and drive unit.
  • high accelerations can also be realized by drives with comparatively low power in the adjustment of the stop and / or gripping and / or measuring element, whereby a high adjustment speed and therefore short cycle times can be achieved.
  • the rotary joint between stop and / or gripping and / or measuring element and support arm is designed as a rotary drive, such as a servomotor.
  • a rotary drive is any angle ⁇ between the stop and / or gripping and / or measuring element and a normal, standing on a working plane of the bending press X-axis in the rotary drive variably adjustable.
  • the greatest possible freedom of application of the backgauge unit is ensured by the free adjustability of the angle of rotation of a stop and / or gripping and / or measuring element.
  • a straight sheet can be struck, but also a sheet, which already has a bending point, and therefore is not aligned horizontally in the stop area.
  • a gripping element for example, can carry the sheet actively in the bending process by the free adjustability of the angle of rotation, or change the tool on the bending press and transferred to a tool storage.
  • a stop and / or gripping and / or measuring element parallel kinematic, eg via linkage or traction mechanism, is formed, so that the angle ⁇ between stop and / or gripping and / or measuring element and the X-axis is always the same regardless of the position of the support arm.
  • the stop and / or gripping and / or measuring element is mounted on the swivel joint via a quick-change device and / or has at least one stop finger.
  • the quick-change device ensures that the set-up times for mounting the various tools mentioned above, which can be attached to the stop unit, remain as short as possible, and therefore incur the lowest possible machine times. This minimization of machine off-times has a positive effect on the productivity of the machine and therefore also positively on the operating costs of the machine.
  • the stop finger is mounted either as a separate stop unit in order to ensure the greatest possible freedom of use in the stop position, or that the stop finger is part of the gripping or measuring tool, for example, without tool change between the individual processing operations get along.
  • a plurality of stop fingers are mounted in the execution of a tool turret on the circumference to bring different Anschlagfingergeometrien used.
  • a measuring unit detects a torque which is initiated by a force exerted at a distance from the axis of rotation and normal to the stop finger.
  • detecting the torque can be detected in certain positions of the stop finger, the force exerted on the stop finger stop force.
  • a gripping element for actively guiding the sheet to be bent
  • a deviation of the actual position of the sheet to the desired position can be detected via the torque.
  • a collision of the stop and / or gripping and / or measuring element can be detected with an object, whereby the personal safety can be increased, since a risk of crushing is prevented by detection.
  • Another Advantage is that a possible jamming of the bending tool can be detected in a bending tool change.
  • the stop finger has a plurality of abutment surfaces, which are retrievable or actively predetermined with respect to their position and their position by a control device.
  • the stop finger not only, as a conventional stop finger, can be used as a stop for a straight plate, but that also bent and already bent sheets can be positioned with the stop finger by the orientation of the stop finger changed -, and one of the other stop surfaces is used for positioning.
  • the dimensions of bending sequences can be realized more accurately.
  • the stop finger has a stepped shoulder, whereby two mutually perpendicular stop surfaces are formed.
  • the advantage here is that the sheet can be positioned on a stop surface in a horizontal position and at the same time supported by the right angle on horizontal stop surface sheet, to prevent bending of the sheet by the action of gravity.
  • the guide rail has separate, mutually parallel guide surfaces for the guide elements of the support arm and the support arm.
  • a drive of the two guide elements can be implemented, in which they can be moved independently of each other.
  • the guide element of the support arm and the guide element of the support arm on the common guide rail are independently displaceable by two mechanical Versteilantriebe in the guide direction.
  • a longitudinal and a height positioning of the stop and / or gripping and / or measuring element on the position of the support arm and the support arm to each other can be achieved.
  • the independent drives can also be achieved that the guide elements can be moved past each other, and therefore an inverse position is possible.

In this case, however, the back gauge unit 7 would have to be measured exactly to the machine frame 8 after installation.
