Definitions

  • the invention relates to a method for extruding a bolt provided in a transducer, in particular made of light metal, into a hollow profile through the shaping cross section of a die, which is assigned a mandrel that determines the inner contour of the hollow profile.
  • a ram an apparatus for extrusion with a ram.
  • the inventor has set itself the goal of producing a hollow profile with a flange attached in one piece in a cost-effective manner.
  • a seamless and one-piece flange tube preferably made of light metal, is created, which meets increased strength requirements and can be produced in a single operation, avoiding the bolt part that remains after the bolt has been formed and is to be sheared off.
  • a molding cavern is connected directly upstream of the shaping cross section on the die in the pressing direction, the radial extent of which is greater than the width of the shaping cross section and in which the compressed matrix laterally over the hollow profile cantilevered flange forms.
  • the removal of the finished hollow profile with flange from the extrusion press is carried out according to the invention in the pressing direction, for which purpose the die is separated radially into at least two die parts and the surfaces delimiting the shaping cross-section - primarily formed in part-ring shape - are arranged such that they can be moved with respect to one another with the die parts.
  • the divided surfaces delimiting the shaping cross-section can be moved apart by an amount forming a gap which is larger than the corresponding extension of the flange, so that the latter can be extended by the tool or the die.
  • the parting surfaces of the die parts - and possibly the parts of a tool holder holding these die parts - run diagonally through the flange plan, i.e. through two of the floor plan corners. These corners preferably determine vertical dividing surfaces, which allows the die parts to be moved laterally.
  • each of the die parts sits in a corresponding part of that multi-part tool holder.
  • the radially divided die is held together during the pressing process by a surrounding pressure ring, which in the context of the invention either represents a separate machine part or is formed by the block receiver.
  • the advantage of the conical connection surfaces between the die and the block receiver or pressure ring is that the axial connection is easy to produce and can be interrupted again.
  • the contours of the molded cavern determine the shape of the flange, it is also possible, for example, to design it with ring ribs or the like if there are corresponding grooves in the cavern floor.
  • a hollow press ram 4 projects into a bore 5 of a block receiver 6 according to FIG. 1 9 in - not shown - rest position of the press ram 4 is dimensioned such that in this rest position of the transducer bore 5, a hollow bolt B made of light metal can be placed through a loading carriage 11. If the pin axis A is coaxial to Press axis E aligned, the bolt B is inserted by the press ram 4 in the pressing direction x into the sensor 6.
  • a die 20 is seated in a tool holder 19 as a molding tool.
  • the tool holder 19 is supported against a crosshead 21 at the press exit.
  • tool holder 19 and die 20 are divided on the vertical diameter D of the circular shaping cross section or die opening 23 and can be moved apart in the radial direction z; the shaping cross section 23 thus limit two half rings 24, 24 a . From these, an outlet channel 25 widens conically to a through opening 26 of the crosshead 21.
  • an indentation 30 lies in front of the die opening 23 in the die 20, the greatest width b of which is slightly larger than the diameter f of the receiver bore 5.
  • the side walls 31 of this indentation 30 delimit an almost square outline according to FIG. 3 and are one Embodiment curved (31 a in Fig. 5).
  • the pitch diameter D forms a diagonal through two mutually opposite molding corners 32, which are thus located on the tearing surfaces 33 of the die 20.
  • This indentation 30 takes up a part of the matrix 8 1 emerging from the bolt B, which is formed into the hollow profile 3 during the pressing process.
  • This consists of a tubular part 35, the inner contour of the mandrel column 14 and the outer contour of the half rings 24, 24 a of the die opening 23 are determined, and a flange 36 integrally formed therewith with a height i.
  • This flange 36 arises from the baling residue of the matrix B 1 .
  • the distance of this flange 36 from the side walls 31 of the indentation 30 is shown exaggerated in FIG. 3.
  • the flange 36 can be removed after pressing the bolt B completely and moving the die halves 20 a and 20 b (FIG. 5) between them in the pressing direction x. Before the extruded hollow profile 3 is pulled off, the mandrel column 14 is retracted, flange corners 36 e being supported against the transducer face 18.
  • the die 20 extends in the pressing direction x from its die front 40 to form a truncated cone-like closing pressure surface 41 of a length n up to an annular surface 42, which is a shoulder-like ring shoulder 43 follows; the latter abuts an annular rib 44 of the tool holder 19.
  • the closing pressure surface 41 which is inclined at an angle w of, for example, 15 ° to the press axis E, encloses an approximately parallel pressure wall 49 of a central recess 50 of the one-piece block receiver 6, as is particularly clear from FIG. 4.
  • the closing pressure surface 41 can also be encompassed by a closing ring 51, which abuts a nose 52 of the die 20 and whose thickness h corresponds at least to the height i of the flange 36.
  • FIG. 7 An embodiment of FIG. 7 is produced thanks to a shaped groove 45 of the die 20, delimited by a shaped rib 46, a flange 36 with a circumferential rib 37, the flange 36 projecting over the die front 40; the projecting flange part is formed in a shaped cavity 54 of the transducer face 18, to which the central transducer opening 50 connects in the pressing direction x.
  • flange tubes 3 in one piece, which can be used, for example, as recipients for centrifuges of uranium separation systems.
  • the floor plan of the flange 36 which is determined by the indentation 30, is freely selectable, as is the diameter d of the flange tube 3. It is also up to the respective circumstances whether conventional hollow bolts B are used or these are tempered beforehand.
  • the device for solution annealing of the bolt B is not shown in the drawing.
  • the mandrel column 14 can be designed to move along or be a fixed part of the press ram 4.
