  • the centering piece can be fixed on both sides of the mandrel axially by clamping elements.
  • the diameter of the inner bore of the hollow block is preferably larger than the outer diameter of the mandrel prior to its forging.
  • the mandrel bar with the mandrel is advantageously centered in the hollow shaft of the block manipulator and thus directly at the scene of action with the proposed solution and guided therein during the axial positioning movements of the manipulator and / or the mandrel rod actuator centrically supported over the entire length of the hollow shaft ,
  • the mandrel bar is provided with a centering or centering ring, the outer diameter of which corresponds approximately to the inner diameter of the hollow shaft of the block manipulator.
  • the proposed method and apparatus are advantageously used.
  • the deflection of the relatively long mandrel can be efficiently prevented by the use of the centering or at least considerably minimized.

  • the block manipulator 2 faces with its loading side of a forging machine 3, in which the hollow block 1 can be forged by radially from outside acting on him forging tools 18.
  • the forging with the forging tools 18 takes place only when in an inner bore 7 (s. Fig. 7 ) of the hollow block 1, a mandrel 5 is placed.
  • the mandrel 5 is arranged at the axial end of a mandrel bar 4.
  • the mandrel rod 4 together with the mandrel 5 is guided through a central bore 6 (hollow shaft) in the block manipulator 2 and inserted into the inner bore 7 when the hollow block 1 is held by the tongs 13, 14.
  • a mandrel manipulator 16 is arranged laterally next to the mandrel rod 4, on which a carriage 17 is arranged for a rotary drive of the mandrel rod 4. According to Fig. 1 the mandrel 5 together with mandrel bar 4 is placed on the supports 15.
  • Fig. 3 then moves the block manipulator 2 back, ie to the mandrel manipulator 16 and threading the mandrel 5 together with mandrel 4 in the central bore 6 of the block manipulator 2 (the central bore 6 is incorporated in a hollow shaft, which is part of the block manipulator 2).
  • the mandrel manipulator 16 itself may have a drive and make the threading.
  • Fig. 5 closes the pivoting of the hollow block 1 at.
  • the hollow block 1 is gripped and clamped by the tongs 13, 14, ie the block manipulator 2 clamps the hollow block 1 in preparation for forging.
  • the forging itself is done according to Fig. 6 , ie the block and mandrel manipulators 2 and 16 move to the forging position.
  • the mandrel 5 is arranged axially in the hollow block 1 so that the forging process with the forging tools 18 can take place above it.
  • FIGS. 1 to 6 So show the sequence sequence of producing a tubular workpiece from the hollow block 1 in time sequence of placing the mandrel 4, preferably on block supports and an additional support with which the machine bed 19 is formed, until threading the mandrel 4 with a subsequently explained centering 8 in the central bore (hollow shaft) of the block manipulator 2 and ultimately the center-based guiding the mandrel bar via its centering in axial movements of the manipulator and / or the mandrel rod actuator, designed as a mandrel manipulator slide.
  • the mandrel bar 4 has at least one centering piece 8 (in the embodiment, it is exactly one centering piece 8). Details are in Fig. 7 represented in which the most important parts of the device can be seen.
  • the outer diameter D Z of the centering piece 8 is slightly smaller than the inner diameter D I of the central bore 6 of the block manipulator 2.
  • the outer diameter D A of the mandrel 4, however, is smaller than the outer diameter D Z of the centering. 8
  • the centering piece 8 consists essentially of two parts, namely a radially inner part 8 'and a concentrically arranged radially outer part 8 "(it should be noted that for assembly-technical reasons, the outer part 8" must be again divided to above the inner part 8 'can be mounted).
  • the inner part 8 ' has a convex outer periphery 9, as in the radial section according to Fig. 7 shows.
  • the dome-like design has the advantage that there is always a centric load in the central bore 6 (hollow shaft) of the block manipulator 2.
  • the inner part 8 ' is clamped in both axial directions by means of clamping elements 11 and 12 Mandrel bar 4.
  • the shifting and in particular threading the Mandrel 4 and thus the centering 8 in or in the central bore 6 is facilitated by a chamfer 10, which is incorporated into the outer part 8 ".
  • the inner wall of the inner bore 7 touches.
  • the wall of the inner bore 7 is usually coated or provided with a lubricant or release agent. Accordingly, when inserting the mandrel 5 into the inner bore 7, an air gap remains between the mandrel and the inner bore, as shown in FIG Fig. 7 is indicated.
