Definitions

  • the invention relates to a double-head pipe bending machine, namely a pipe bending machine with two on one Machine frame attached bending heads, according to the Preamble of claim 1.
  • the usual pipe bending machines have a machine frame a bending head with a rotatable bending template and one the tube against the bending template pressing jaw, which is attached to a swivel arm is. By swiveling the swivel arm and simultaneous rotation of the bending template becomes too bent pipe section around the bending template.
  • Double-head pipe bending machines are also known have two bending heads.
  • the pipe to be bent is on the bending templates of both bending heads and the Swivel arms with the associated jaws pivoted at the same time around the outer pipe sections to bend.
  • double-head pipe bending machines only straight tubes can be bent, but not tubes, that are already pre-bent.
  • the invention has for its object a double-head pipe bending machine to create who is able complex bending processes without retrofitting on the same Machine.
  • a double-head pipe bending machine from which the generic term of claim 1 is known from US-A-4 843 859.
  • On the A sledge is attached to the machine bed Longitudinal direction of the machine bed is movable and a Pipe holding device carries.
  • the Carrying part moved such that one of the bending heads in the Work position arrives while the other bending head away from the work position in a waiting position is in which he must remain until the Processing by the other bending head is finished.
  • the invention has for its object a double-head pipe bending machine to create the bigger one Flexibility with regard to the mobility of the two bending heads Has.
  • the double-head pipe bending machine there are two bending heads facing the same direction from that Machine frame. This direction is called the longitudinal direction designated.
  • a pipe to be bent into a Pipe holder is clamped, one of the Bending heads fed to be bent by this. After completing this first bending process, this will be Pipe released from the first bending head and the pipe holder with the cross slide in the transverse direction procedure to attach the pre - bent pipe to the to attach the second bending head that follows Bends.
  • the fact that a single pipe holder Serving both bending heads is for one complex bending process only one clamping of the pipe is required.
  • Pipe bending machine also used for mandrel bending can be, with a mandrel in the interior of the tube is pushed in, the pipe section not to be bent reinforced. Furthermore, on the bending heads Wrinkle smoothers can be used.
  • the bending heads move the pre-bent tube to the second bending head after being released from the do not hinder the first bending head, are the bending heads movable on the machine frame, for example in Longitudinal direction and / or in the transverse direction and / or in the height direction.
  • the double-head pipe bending machine has a machine bed a machine frame 10, which all components wearing. From an end wall of the machine frame 10 are two bending heads 11 and 12. Each of these Heads has a support member 13 on its top a rotatable bending template 14 carries on her Has circumference at least one bending groove into which the half of the circumference of the pipe to be bent is used becomes.
  • a pivot arm 15 is also on the support part 13 provided around the vertical axis of rotation of the bending template 14 is pivotable and a jaw 16 carries the tube 17 against the circumference of the bending template 14 presses.
  • the jaw 16 also has a groove that encompasses part of the circumference of the pipe.
  • the clamping jaw 16 is a pressing device 18 pressed against the bending template 14.
  • the unbent pipe section is supported by a slide rail 19 supported on a protruding from the support member 13 Support arm 20 is provided and a pressing device 21 are pressed laterally against the pipe can.
  • Each bending head 11, 12 is along a vertical guide 23 on the machine frame 10 movable in height. A is used to drive this vertical movement Spindle 22.
  • the bending heads can also be moved in the longitudinal direction its distance from the machine frame 10 to change. Also a movability of the bending heads 11.12 in the transverse direction, that is to say parallel to the side of the Machine frame to which they are attached is possible.
  • Fig. 1 the two bending heads 11, 12 are in the respective Pipe receiving position shown, the Swivel arms 15 are directed towards each other.
  • the bending heads are therefore mirror images of each other.
  • the bending templates 14 Since the radii of the bending templates 14 the pipe curvature determine and since the bend grooves to the pipe diameter are adapted, the bending templates 14 can easily be replaced, as well as the jaws 16.
  • the pipe holding device 25 On the machine frame 10 is the pipe holding device 25 provided on a cross slide 26.
  • the Cross slide 26 consists of a cross slide 27, the in the transverse direction of the machine frame 10 along Guide rails 28 is movable, and a longitudinal slide 29, on the cross slide along guide rails 30 is movable.
  • the Cross slide 27 or the longitudinal slide 29 also in movable in height.
  • the longitudinal slide 29 carries the Pipe holding device 25 into which the unbent pipe 17 is clamped and around the longitudinal axis of the tube is rotatable.
  • the longitudinal direction is the axial direction of the pipe holding device 25 and the transverse direction direction perpendicular to this.
  • a mandrel retraction cylinder 31 On the cross slide 26 is a mandrel retraction cylinder 31 provided, which carries a mandrel 32, which by the pipe holder 25 passes through and not part of the pipe to be bent from the inside.
  • the longitudinal slide is used when the pipe bending machine is in operation 29 moved into the rear end position. Then the pipe is clamped in the pipe holder 25.
  • the tube 17 is moved by moving the longitudinal slide 29 and the cross slide 27 laterally to the Bending template 14 of the bending head 12 created while the clamping jaw 26 and the slide rail 19 are in the Treatment position. Then the jaw 16 and the slide rail 19 pushed towards the tube 17, so that the tube between the bending template 14 and Clamping jaw 16 is clamped. Then the swivel arm 15 and the bending template 14 pivoted around the bending angle, so that the tube 17 is bent. Since that The tube is pulled, the longitudinal slide 19 advanced in the longitudinal direction.
  • Fig. 2 shows a bent tube with the double-head tube bending machine 1 are produced can.
  • This pipe has several bends in different ones Room levels on, with the individual pipe bends have different radii of curvature.
  • the plane in which the bend is made is turned the pipe holding device 25 about its longitudinal axis set.
