  • the clamping jaw used for forming is moved in the direction of the bending core.
  • the tube in question is clamped between the bending core and the clamping jaw.
  • the bending core is rotated about the bending axis and at the same time the clamping jaw is pivoted about the bending axis.
  • the clamped between the bending core and the jaw tube is thereby pulled around the bending core.
  • a slide rail of the bending tool is arranged upstream of the clamping jaw on the side remote from the bending core of the pipe to be bent.
  • Object of the present invention is to provide a bending device and a bending tool that allow flexible workpiece machining.
  • this object is achieved by the bending tool according to claim 11, as well as by the bending device according to claim 1, comprising the bending tool according to claim 11.
  • the functions bending bending and roll bending are integrated into a single bending tool.
  • the user has the choice of which of the two bending methods he uses.
  • it is possible to create on the same workpiece both bends after the drawing bending process as well as bends after the roll bending process.
  • Characteristic of the drawing bending process are the clamping of the workpiece to be bent between the bending core and clamping jaw and the pulling of the thereby moving in the direction of the workpiece axis workpiece around the bending core.
  • no movement of the workpiece to be machined takes place in the direction of the workpiece axis.
  • Rolling bending elements which can be considered are both bending tool parts which roll on the workpiece surface during said relative movement, as well as bending tool parts which slide along the workpiece surface.
  • the bending device according to the invention and the bending tool according to the invention are able to handle machining tasks of various kinds. Pull bending is preferred, for example, when only a small workpiece length is available for applying the bending tool downstream of the bend to be created.
  • Pull bending is preferred, for example, when only a small workpiece length is available for applying the bending tool downstream of the bend to be created.

  • Such short clamping lengths are available, for example, in machining cases in which bends are to be created on a workpiece, which have only a small mutual distance along the workpiece axis. Bends close to each other are to be created, for example, in the manufacture of fuel and brake lines and of exhaust systems for motor vehicles.
  • Roll bending is characterized by its particularly easy implementation. Neither is the workpiece to be clamped in the bending machining between the bending core and the roll bending member nor does it require a rotation of the bending core associated with the bending pivotal movement of the roll bending member.

  • either the drawing bending unit or the roll bending unit of the bending tool can be transferred to the position in relation to the workpiece clamping in which it can be used to create a bend on the workpiece.
  • the verticianlich claim 6 provided mobility of the bending tool in the transverse direction of the workpiece axis allows, for example, make the change of the bending unit to be used in fixed at the Maschinen Swisseinponent workpiece. After opening the bending tool this is moved in the workpiece transverse direction until the workpiece comes to rest outside the bending tool. Subsequently, the for the change the bending devices required to be used rotational movement of the bending tool are performed around the tool axis of rotation.

As a result, it can be freely selected from which side of the clamping of the workpiece a workpiece which is to be bent several times is machined. You can also change the page of editing. If the bending tool is also rotatable about a tool rotational axis according to claim 5, the position change of the bending tool can be connected from one side of the workpiece clamping to the opposite side with a change of the bending unit to be used and possibly also with a change of the bending direction.
  • the invention type of construction according to claim 8 is characterized in that the tool rotation axis serving for positioning the bending tool relative to the workpiece to be machined coincides with at least one axis of the bending operation to be performed by means of the bending tool.
