Definitions
- Bieaekopf for bending rod and tubular workpieces
- the invention relates to a bending head for bending rod and tubular workpieces, with a rotatable about an axis holder which carries a bending mandrel at one axial end, and with at least two other tools, each having a holding body with the bending mandrel facing the axial End comprise a bending pin and each of which, in each case independently of the other tools, is rotatable.
- a bending head for a bending device for rod-shaped and tubular workpieces in which the workpiece is clamped between a central bending mandrel and a clamping device movable relative thereto and bent by pivoting the bending mandrel and the clamping device when the workpiece is clamped .
- This known bending head operates with a plurality of axes of rotation, one of which serves to rotate the bending mandrel, while another is associated with the pivoting of the clamping device. Another axis of rotation is intended to cause a clamping movement by radially advancing the clamping device against the workpiece (or back).
- this known bending machine can be a bending of the workpiece in two opposite bending directions without changing the bending head, but is very complicated and not very flexible when using a once mounted bending mandrel, with complex components can not be produced.
- a bending machine for rod and tubular workpieces which has a bending head with a circular disc, which carries in its center a bending mandrel and is pivotable about a central bending axis. Further, a jaw is provided which is rotatably mounted about a second axis on the circumference of a turntable, which in turn can be rotated about an axis parallel to the central axis of bending and mounted at a distance from this axis on the circular disc.
- a bending head of the aforementioned type is described in WO 2010/080522 A2.
- This known bending head can work with two or more tools, which are mounted on a turntable on the center of a bending mandrel mounted around it and at a distance from it and formed independently rotatable by their own rotary actuators.
- This known bending head also allows the production of complicated bending forms, but is very complex in its overall structure at the same time a very large space requirement.
- the invention aims to develop such a known bending head such that it has a significantly reduced space requirements and a less expensive construction while maintaining its suitability for producing very complex bent parts.
- the invention proposes a bending head of the type mentioned, in which the holding body of the tools are arranged concentrically to the holder of the bending mandrel and pivotable about its axis of rotation.
- the holding body of the tools are designed as concentric with each other in running hollow shafts, sitting in the radially innermost of the holder of the bending mandrel rotatable.
- each tool consists of a holding body with a projecting at the radial end surface bending pin. Since its diameter is usually not very large, and the wall thickness of the holding body to which the bending pin is attached, in the radial direction can also be made relatively small, so that a total in conjunction with the concentric arrangement of the holding body and the mandrel a very considerably smaller space requirement for the bending head according to the invention than in the generic bending head.
- the holding body of the individual tools and the holder of the bending mandrel in each case independently, are rotatable, can be rotated independently during operation of the mandrel and the bending pins, wherein for each of these elements twisting in both directions of rotation is possible.
- each of these can have an extraordinary effect due to these three concentrically arranged individual elements taking into account the two possible directions of rotation large variety of different constellations of mandrel and bending pins are achieved with each other, which is given a remarkably large flexibility.
- the production of very complex bent parts is possible.
- the holding bodies of the tools are designed as concentric hollow shafts, in whose radially innermost the holder of the bending mandrel is rotatably seated, a very small space requirement of the bending head according to the invention is achieved without any restriction of its flexibility.
- An advantageous embodiment of the bending head according to the invention also consists in that the bending mandrel and / or the bending pins between an active operative position in which they act during bending on the workpiece to be bent, and a non-active rest position parallel to the axis of rotation of the bending mandrel are adjustable. This ensures that parts of the bending head in addition to the rotational movements that they can perform, are also lowered, which means that the tool rims (single or multiple, independent or shared) or the mandrel lowered below the bending plane and z. B. can be raised again on the other side of an inserted workpiece.
- a bending pin which is not required for this bending operation, move out by lowering its holding body from the bending plane, so that it can not interfere with the subsequent bending operation.
- the holding body of the tool with the radially outermost bending pin is rotatably mounted on an upper end wall of a housing and is in driving connection with a first rotary drive mounted on this housing, in particular on its upper end wall.
- the holding body of the tool with the radially outermost bending pin preferably has an outer toothing, preferably in the vicinity of the upper surface of the end wall of the housing, which is in meshing engagement with a gear connected to the first rotary drive, wherein, again preferred, the first rotary drive on the side facing away from the bending pins of the tools of the upper end wall of the housing is attached thereto.
- a particularly great flexibility of the bending head according to the invention can be achieved in that the holder for the mandrel as well as the holding body for the other tools are each connected to its own rotary drive, so that a complete independence of their movements can be reached.
- first rotary drive is connected to a first lifting device, which is designed for stationary mounting on a machine frame of a bending device and, after being mounted there, allows a process of the entire bending head with all its associated facilities parallel to the bending axis ,
- the holding body of each tool is connected to a device by means of which it can be moved from a non-active rest position to an active operative position (and vice versa), which means moving out of the bending plane or driving it into each of them used tools allows.
- An advantageous embodiment of the invention also results when the holder of the bending mandrel is connected at its axial end opposite the bending mandrel to a second rotary drive which is attached to a first plate, which in turn by means of a second lifting drive together with the second rotary drive and the holder for the bending mandrel in the direction of the axis of rotation of the latter is movable.

- This embodiment makes it possible to move the holder for the radially innermost bending pin relative to the mandrel and the holder of the latter in the longitudinal direction of the axis of rotation of the mandrel, thus in particular the bending pin while maintaining the bending mandrel in the bending plane or the mandrel while maintaining the innermost bending pin lower in the bending plane.
- the second lifting drive preferably comprises on the output side a spindle shaft on which a spindle nut attached to the first plate is seated, wherein the spindle shaft is rotatably mounted with its axially projecting end portion in a second plate spaced a distance from the first plate but stationary in the axial direction of the spindle shaft is and the second plate surrounding the bending mandrel holding body of the tool for the radially innermost bending pin at its end facing away from the bending mandrel axially opposite her rotatable, but held stationary in the direction of the axis of rotation bears.
- the second plate also carries a third rotary drive, by means of which the holder for the radially innermost bending pin can be driven in the direction of rotation.
- This makes it possible to mount the drive for the holder for the radially innermost bending pin in a particularly space-saving manner within the overall device.
- a third lifting drive is provided, by means of which the second plate is longitudinally displaceable in the direction of the axis of rotation of the bending mandrel.
- all rotary and lifting drives are covered by a downwardly open housing, protruding on the upper end wall of the bending head to the outside.
