Definitions

  • the invention relates to a method and an apparatus for producing pressure-rolled tubes according to the preamble of claim 1 or 2, (see e.g. FR-A-468 918).
  • DE-A-44 46 919 describes a method for Ironing presses of internally toothed parts are described, whereby on a Mandrel a workpiece is arranged, which by applying force from Spinning rollers is plastically deformed.
  • the synchronous pressing method is detailed and described the counter-rotation pressing method.
  • the pressure rolling technology allows the weight advantages to be exploited to the full due to the smallest wall thicknesses because of the highest solidifications that can be achieved used materials (steel, steel alloys, aluminum and Aluminum alloys, titanium and titanium alloys, copper and copper alloys, Stainless steels etc.) and the extreme uniformity of the manufactured parts.
  • the method allows, in particular, inside the Workpieces with excellent surfaces, i.e. the roughness is extreme low. These low surface roughness ensure special Protection against cracks caused by internal notches in e.g. Exceed overloads can.
  • the process also allows high repeatability. Scattering within the work pieces is minimal.
  • the invention has for its object a method according to the preamble of claim 1 and an associated device according to the preamble of claim 2 further develop with them Cost-effective and tolerance-accurate pressure-rolled pipes with inner Wall thickenings can be made at the ends.
  • the outer diameter of the first mandrel corresponds to that Desired inner diameter of the undickened middle area of the finished pipe and the outer diameter of the paragraph corresponds to that desired inside diameter of the wall thickening.
  • the mandrel and / or the shoulder is open provide a profile on the outside.
  • the profile can only be on be attached to certain sections and advantageously consists of Ribs and grooves. However, any other conceivable profile is possible.
  • the mandrel and / or the shoulder is at least partially a polygon in cross-section, e.g. a hexagon.
  • a mandrel is here of course the first or the second mandrel or both.
  • This method and this device are particularly suitable for the production of structural parts for bicycles / motorcycles.
  • Fig. 1 shows schematically the first operation on a pressure rolling machine for the production of a tube 3 with end wall thickenings.
  • the pipe 3 is arranged on a first mandrel 1a and is by Force application of the pressure rollers 2 plastically deformed.
  • the outer diameter of the first mandrel 1a corresponds to that desired inner diameter of the later thickened central area of the finished pipe 3.
  • a tailstock-side shoulder 4 is arranged on the first mandrel 1a, the outside diameter d 1 of which corresponds to the desired inside diameter of the end-side wall thickenings of the finished tube 3.
  • the spinning rollers 2 begin on the tailstock-side paragraph 4 their forming work and work in the direction of not shown Machine spindle.
  • the feed of the spinning rollers 2 is 8 indicated.
  • Fig. 2 shows the semi-finished pipe 3a produced after this operation with the one-sided wall thickening produced on one side 5.
  • Reference number 9 is the end of processing by the spinning rollers 2 indicated.
  • the semifinished pipe 3a After the semifinished pipe 3a has been removed from the first mandrel 1a, the semifinished pipe 3a is in a second operation (see FIG. 3) on the side with the wall thickening 5 that has already been produced into a lathe chuck 6 (mandrel or the like) mounted in the press-rolling machine. ) clamped.
  • a mandrel 1 b attached to the tailstock is pushed into the semi-finished tube 3a.
  • the second mandrel 1b has an outer diameter d 2 which corresponds to the inner diameter of the wall thickening.
  • the spinning rollers 2 then form the second wall thickening from the tailstock end towards the machine spindle.
  • the reference number 12 indicates the end of processing by the pressure rollers 2.
  • Fig. 4 shows the finished pipe 3 with the end wall thickening.
  • 5 a, b, c show three different tubes 3, each with a different one Inner contour.
  • 5a shows a tube 3 with a hexagonal cross section.
  • 5b, c show a tube with fins 10 and grooves 11.
  • a pressing mandrel 1b with ribs 10 and grooves 11 is shown in FIG. They are one Many variations of these mandrels 1b, as well as paragraphs 4 possible here not all of them can be displayed.
  • the devices allow the Production of conical parts, partially conical parts, combined with partial if necessary different wall thicknesses, as well as with ribs or inside Grooves in one step.
