Definitions

  • the invention relates to a mandrel for a Bending device for pipes, consisting of a rigid Head and a package attached to it with only one end of layered, flexible slats, the perpendicular to the slat plane while sliding the slats is flexible to each other.
  • Such mandrels are used in pipe bending devices used to inside the tube during the bending process support.
  • This support is designed to buckle the tube, a wave formation on the inner bending bend, Flattening on the outer arch, an oval deformation of the Cross-section and a springback of the tube after Bending process can be counteracted.
  • the danger of it to the aforementioned effects when not used Bending mandrel comes in, especially with pipes that are large large ratio of outside diameter to wall thickness have and with a comparatively small radius, e.g. in the order of the pipe diameter should.
  • Typical wall thicknesses of such pipes are e.g. at 1.5 mm with a pipe diameter of 150 mm.
  • JP 619 8349 there is a mandrel of the type mentioned at the beginning known (JP 619 8349), in which between outer, on the Plates made of spring steel on the inside of the pipe Stacked flexible slats forming a package are arranged from plastic. Because the individual slats Being able to slide on top of each other is the one for the bending process bending force to be used compared to the other Bending mandrel made of solid plastic material smaller. Nevertheless, the bending force to be used is undesirable high, especially when pipes with large cross section and small bending radius should be bent.
  • the bending mandrel according to the invention made of lamellae exists, it is because of the material chosen for it "Sheet" is dimensionally stable and can be relatively easily bend because the central slats do not overlap extend the entire cross-section.
  • Bronze is suitable for this, but above all steel, especially spring steel.
  • the bending mandrel can be designed in various ways his.
  • the cutouts are in the cut slats on their not attached Ends open. According to an alternative embodiment they closed at the unattached ends.
  • the closed end can be advantageous for supporting the may be particularly heavily loaded in practice Be the end.
  • the bending force required for bending can continue can be reduced by the fact that at least some slats on its side facing the inner bending arc transversely to have notches running in their longitudinal direction. Also the bending force can be reduced in that between the individual slats sliding on each other a lubricant is provided.
  • the free end of the package can be spherical rounded, cut at an angle or tapering to a point his.
  • the lamellae are in contact with each other during the bending process move that the one on the outer arch Slat opposite the slat on the inner arch referred to the plane perpendicular to the pipe axis would remain the support in this area get lost if not after another Embodiment of the invention would be provided that the Slats have a different length, such that the slats on the side with the big one Bend the greatest length and the slat on the side has the smallest length with the small bending curve.
  • the invention further relates to a method for bending a tube using an inventive Bending mandrel in a bending device with a fixed receptacle for the tube with inserted Bending mandrel, one on the side of the small bending sheet stationary support body and one around the Center piece for the Pipe.
  • such a method is thereby characterized that the pipe and the one used Bending mandrel that extends over the entire length of the Bending arc extends throughout the entire bending process is axially fixed.
  • the method according to the invention is became possible because of the special design of the mandrel, the required bending forces relative are small, so that the bending forces to be applied also despite the greater axial length over which the fins do not slide on each other during the bending process grow uncontrollably large.
  • the tube is used during the bending process held axially fixed, then migrates during the bending process the bending area around the middle of the bending sheet.
  • the flexible mandrel must therefore be correspondingly long be designed.
  • a shorter mandrel comes in alternative method of the invention.
  • This A bending device comes with a method fixed receptacle for the tube with inserted Bending mandrel, one on the side of the small bending sheet arranged, especially around the middle of the bending sheet rotatable support body and one around the same center of the bending arc swiveling guide piece for the pipe to use.
  • Such a method is in accordance with the invention characterized in that the tube and the used Bending mandrel that at least with its flexible part over the bending area of the bending sheet extends during the entire bending process axially freely movable or controlled that the flexible part of the mandrel in the bending effective The area of the bending sheet remains.
  • the pipe can be controlled or free movable according to its different Path speeds on the inner curve and the outer curve Path velocities of the one acting on the pipe Part of the device in the sense of the smallest possible Relative movement can be adjusted.
  • the axial Movement of the tube allows the bending area fixate spatially, so that one can only get over a small length of the flexure extending flexible Bending mandrel gets along.
  • the bending device according to FIGS. 1 and 2 consists of a fixed shot 1, one on the side of the small one Bending arc fixed support body 2 and one pivotable about the center A of the support body 2 Guide piece 3.
  • the starting position for the bending process is a pipe 4 to be bent in the receptacle 1 and extends beyond the guide piece 3.
  • In the tube 4 is a Bending mandrel inserted.
  • the mandrel consists of a rigid head 5 and a package 6 attached to it of stacked slats 6a, 6b.
  • the head 5 has two Fork branches 7,8. There are 7,8 between these fork branches the slats 6a, with the exception of the outer, somewhat shortened slats 6b fastened with bolts.
  • the outer slats 6b are fastened by means of Bolts on the other fins 6a.
  • the slats 6a with the exception of the outer slats 6b window-like recesses 6c to the free end of Pact 6 are open. The simpler representation because of this this is only shown in FIGS. 3 and 5.
  • the outer slats 6b are formed over the entire surface, so that the stacked slats 6a, 6b one Form hollow body in which the individual lamellae 6a, 6b cover each other and support each other.
  • the area of the cutouts 6c can be the lamellae 6a, 6b Have grooves 6d running transversely to the bending plane.
  • the Recesses 6c and the grooves 6d favor the Flexibility of the package 6.
  • the Fig. 3 is further closed remove that the slats 6a, 6b at their free end are held together by a tension spring 9. Furthermore is this Fig. That the slats 6a, 6b a have different lengths.
  • FIGS. 7 and 8 differs from that of FIGS. 1 and 2 in that the support body 2 'about the center A of the bending arc, the tube 4 'is not axially fixed, but is pushed forward and the flexible part 6 'of the mandrel 5', 6'one has a comparatively short length.
  • the tube 4 is held axially fixed.
  • the support body 2 is rotation.
  • the bending mandrel 5,6 is also fixed axially and its flexible package 6 has a length that spans the entire length of the bend of the tube 4 extends as shown in Figs. 1 and 2.
  • a such configuration enables that during the bending process the mandrel 5.6 does not match the bending progress must be adjusted. Therefore, the procedure can be easy and quick to perform and does not lead to internal damage to the tube 4, which is which make it necessary to move the mandrel can happen.
