Definitions

  • the invention relates to a device for bending pipes a bending unit and a bending finger and with a feed device and a holding and moving device for the pipe to be bent.
  • the invention has for its object such a device to design that it can be used universally.
  • the bending unit in two parts is formed with two symmetrically arranged bending dies, each one have outwardly open, annular groove, between which the Pipe is inserted during the bending process, and that the bending finger on a rotatable support body is rotatably mounted, the axis of rotation of the Support body and the bending finger run parallel to each other.
  • the bending finger By superimposing the two rotational movements of the support body and the The bending finger can achieve a wide range for the curve of the bending finger be so that he can make very targeted bends.
  • the bending finger can the course of the contour of the bending die largely on both sides consequences.
  • the two pivot bearings can be rotated independently of one another, which is due to separate drives or by a control link.
  • An advantageous embodiment of the invention is characterized in that the Bending unit is rotatably mounted about the longitudinal axis of the pipe to be bent.
  • the bending unit in the longitudinal direction of the pipe to be bent is arranged to be longitudinally displaceable.
  • the pipeline can be bent at any point without having to be displaced itself.
  • the rotatability and the longitudinal displaceability of the bending unit can be combined, so that a universal sequence of the bending process of the entire pipeline is possible.
  • a further embodiment has proven to be very advantageous in that According to the invention, the bending die with the larger bending radii on the outer free End is arranged.
  • the Bending finger is arranged adjustable in height.
  • a further advantageous embodiment of the invention is characterized in that the feed device for the pipeline to be bent and is mounted for longitudinal displacement and for both feeding and holding during of the bending process and for longitudinally displacing the pipeline.
  • the feed device when pivoted away from the pipeline is longitudinally adjustable.
  • a further advantageous embodiment of the invention is characterized in that in the extension of the longitudinal axis of the pipe to be bent in the device Opening is provided, in which an attached to the pipeline Hose section is inserted during at least part of the bending process.
  • a lever arm is provided which, when the pipeline is brought up to Bending unit guides the hose section into the opening.
  • An advantageous further embodiment of the invention is characterized in that in the area of action of the feeder the end of a transport device for the piping to be bent is provided.
  • the feed device can thereby easily bend a pipeline Remove at the end of this transport device and feed it to the bending device.
  • a stop part is provided at the end of the transport device.
  • a pipe is driven against this stop part, so that an accurate Ready position for acceptance has been reached.
  • stop part is pliers-shaped and slidable along the pipeline is stored and in the clamped condition of a pipeline in the longitudinal direction can push against a stop located there.
  • the Stop part is provided with a recess into which the pipeline is able to intervene.
  • the stop part in Be longitudinally movable of the pipeline.
  • a further advantageous embodiment of the invention is characterized in that the stop part in the region of the recess with a side indentation Inclusion of an intermediate piece between the pipeline and an attached Hose section is provided.
  • the transport device at least two rows of Transport shoes open at the top, in which the pipes individually be transported.
  • a further advantageous embodiment of the invention is characterized in that at least one of the two rows is transversely adjustable.
  • a limit switch is arranged, which Transport device stops when a pipe arrives in the end position.
  • a device for bending pipes 2 is referred to contains a transport device 3 and a bending unit 4.
  • the transport device 3 contains two transport chains 5 and 6, of which one transport chain 6 laterally is adjustable (double arrow). Open on the top of the two transport chains Transport shoes 7, in which the pipes 2 are inserted.
  • a limit switch 8 is provided, which at Arrival of a pipeline 2 switches off the drive of the transport device.
  • This end position there is also a stop part 9, in which the Pipe 2 retracts.
  • This stop part 9 has two mutually movable jaws for clamping the pipeline.
  • the stop part 9 is also parallel to Pipeline 2 movable, making it against the end of the clamped pipeline is able to push a stop 10. The respective pipeline is then exact aligned and can be passed to the bending unit 4 without problems.
  • a feed device 11 is provided on the bending unit 4, which is pivotally mounted on the bending unit.
  • the radius of action of this feeder 11 is such that on the one hand it is the last pipe 2 in the Transport device to grasp and on the other hand this pipeline in the bending unit can bring.
  • the feed device is also longitudinally movable, whereby the pipeline 2 is displaceable within the bending unit.
  • the feeder is also in a swiveled away from the pipeline Intermediate position also longitudinally displaceable, which means that they are at the end of the Drive the bending unit arranged over the bending head 12 and the pipeline on it Can take sides.
  • a pipeline 2 is shown, which is additionally on a End is provided with a hose section 22 which via a connecting piece 23rd is firmly connected to the pipeline 2.
  • the stop part 9 To align such a trained Pipe with hose section in the transport device 3 is the stop part 9 provided with a side indentation 29 into which the connecting piece 23 engages in the lateral movement of the stop part. In a defined position of the Stop part 9, the pipeline is then aligned accordingly.
  • the bending head 12 of the bending unit 4 is equipped with two opposing bending dies 13 and 14, each of which is provided with a circumferential groove into which the pipeline comes to rest during the bending process.
  • a bending finger 15 is provided for bending, which can move along the contour of the circumferential groove of the respective bending die.
  • This bending finger is designed as a pivot lever and is rotatably supported, its bearing itself being rotatably supported again.
  • each bending die 13 with two superimposed cams is equipped, the different Have diameter.
  • the height is adjustable, the outer bending die or the inner one has a larger one Diameter than the other.
  • the bending head 12 is around together with its drives an axis 16 rotatable, in which the pipeline is also located. With a fixed feed device 11, which clamps the pipeline, the bending head 12 in the move the respective bending position lengthways as well as turn. The bending finger 15 then turns in the intended direction around one or the other bending die according to the intended bending angle.
  • the bending head 12 is shown in somewhat more detail in FIG.
  • a double-formed die 13 is arranged, the upper section of which has a smaller bending radius than the lower section.
  • the bending finger 15 acts in the figure together with the lower section, so that in this state a inserted pipe would be bent with the larger scale. Through a The bending finger 15 can also move out adjacent to the die section can be brought into active connection with the smaller bending radius.
  • the upper section of the Bending die it is also possible to use the upper section of the Bending die to be provided with the larger bending radius.
  • the bending finger 15 is rotatably supported in a bearing 18;
  • a storage 19 is provided, in which the bearing 18 of the Bending finger 15 is rotatably mounted. This storage 19 is via a drive 20th turned. This allows the bending finger to make two overlapping rotary movements execute separately or over a common backdrop (not shown) are controllable.
