Definitions

  • the invention relates to a method and an apparatus for producing a workpiece with internal toothing, in particular a ring gear, according to the preamble of the first claim.
  • Such internal gears are generated for example by pressure-rolling.
  • a cup-shaped preform is gem. DE 198 30 817 A1 pressed by means of tapered rollers during a feed movement against a tool chuck, which has the outer profile of the internal teeth to be generated, and reduced in diameter, wherein the preform rotates relative to the tapered rollers.
  • the material of the cylinder wall region of the preform flows into the profile of the tool chuck, whereby the inner profile of the workpiece is generated.
  • the disadvantage is the workpiece material demanding high flexing work in the flow-forming and thus insufficient quality of the internal teeth produced.
  • the flexing work is also associated with a high local energy input, which leads to energy losses. Due to the high stress of the tool chuck, it often comes to a breaking out of the outer teeth shown therein.
  • the productivity of this method is relatively low with a high device cost, because it can be made only 3 to 4 parts per minute.
  • JP 61 038732 A describes the production of a workpiece with internal toothing by means of ironing, wherein an upper die is lowered and thus a further die is pressed against a cup-shaped preform whose bottom has an elongated formation running in the direction of the upper die.
  • the face of the preform is seated during the downward movement on a stop of the mandrel, which in turn is held shock-damped by hydraulic cylinders. Due to the very specific design of the preform or the workpiece and, accordingly, the tool, this device has only limited use.
  • the object of the invention is to provide a method and apparatus for energy-saving production of a workpiece with internal teeth, in particular a ring gear, which ensure a significant increase in productivity with high quality of the internal teeth in a relatively simple structural design of the device.
  • the device for producing a workpiece with internal teeth in particular a ring gear for transmission, has a mandrel with an outer profile corresponding to the internal teeth to be generated, and a forming tool, which reduces the outer diameter of a cup-shaped preform during a feed movement, whereby material of the cylinder wall area in the outer profile the spine flows.
  • a drawing ring is used as the forming tool, which ensures ironing of the cylinder wall area during the advancing movement and acts on the preform during the ironing two tool elements generating axial compressive stresses in the cylindrical side wall of the preform, the preform being directed towards the end face of the cylindrical side wall first die element in the form of an axially movable, designed as a cylindrical pressure sleeve plunger is arranged such that it acts during the ironing on the end face with a force.
  • an axially movable counter-holder is arranged such that it acts during the ironing on the bottom of the bottom of the preform with a counter-holding force.
  • the counter-holder can have a circular pressure surface pointing in the direction of the underside of the base, which acts essentially on the entire bottom region, or an annular pressure surface, which is adapted to the width of the cylinder wall of the preform and aligned substantially flush with it, and onto the edge region of the preform Bottom of the bottom of the preform acts.
  • the pressure stamp is axially movable in the direction of the advancing movement of the drawing ring by a movement corresponding to the ironing length of the preform.
  • the axial lifting movement of the plunger taking place during ironing can be regulated as a function of its pressure force.
  • the plunger is mounted axially movable via a hydraulic piston.
  • the device may advantageously be integrated in a hydraulic press, consisting of a press table and a press ram.
  • the mandrel is arranged axially fixed on the press table and mounted on the mandrel, axially displaceable via a hydraulic piston, the plunger.
  • the plunger At the press ram of the pull ring are preferably fixed to the frame and the counter-holder preferably arranged axially movable via a hydraulic piston.
  • the plunger is preferably formed as a cylindrical pressure sleeve.
  • The, the length of the Preform adapted, distance of the pressure surface of the plunger to the end face of the mandrel is adjustable for example via spacers.
  • the mandrel is rotatably mounted when producing a helical toothing.
  • the production of the workpiece with internal teeth characterized in that a cup-shaped preform, having a bottom and a substantially cylindrical side wall, over a mandrel, which has the outer profile corresponding to the internal teeth to be generated, is reduced in its outer diameter, so that material of Cylinder wall portion flows into the outer profile of the mandrel, according to the invention reducing the outer diameter by ironing by means of a draw ring and during the ironing additional axial compressive stresses are applied to the cylindrical side wall of the preform, which are produced by two acting on both sides of the cylindrical side wall of the tool elements , wherein in the direction of the end face of the cylindrical side wall of the preform, a first tool element in the form of an axially movable, designed as a cylindrical pressure sleeve, plunger during the ironing on the end face with a force acts.
  • a counter-holder simultaneously acts on the underside of the bottom in order to avoid deformations in the bottom region and to apply a counter-holding force.
  • the counter-holding force of the counter-holder and the force of the plunger should be mutually adjustable so that during the entire Abstreckvorganges a flow of material is ensured in the radial direction to completely fill the contour of the mandrel.
  • the plunger performs an axial stroke movement corresponding to the ironing length of the preform in the direction of the advancing movement of the drawing ring, which is regulated as a function of its pressure force.
  • the productivity can be increased by 4 to 6 times in comparison to the spin forming.
  • Fig. 1 and 2 the basic structure of the device integrated in a press is shown.
  • the lower tool part 2 On the press table 1, the lower tool part 2 is arranged, which has a first hydraulic piston 3.
  • On the lower tool part 2 is axially fixed on a punch 4 of the mandrel 5 is fixed, which has an outer profile 6.
  • the hydraulic piston 3 is mounted on an adapter 8 of the printing sleeve designed as a pressure piston 9 axially movable.
  • the axial position of the plunger 9 can be changed over distances 10, the between Adapter 8 and plunger 9 are attachable.
  • the tool upper part 11 is arranged on the press ram P and has a counter-holder 12, which is axially adjustable via a second hydraulic piston 13.
  • the drawing ring 14 is further fixed to the frame via an adapter 15.
  • Gem. Fig. 1 the cup-shaped preform N was inserted with the cylindrical side wall N1 down over the mandrel 5, so that the end face N2 in the direction of the plunger 9 and the bottom of the bottom N3 in the direction of the anvil 12 has.
  • the hydraulic piston 13 moves the counter-holder 12 in the direction of the tool lower part until the counter-holder 12 rests against the underside of the base N3.
  • the frame-mounted on the press ram P frame 14 moves in the forward stroke with the press ram P in the direction of the press table 1, simultaneously the first hydraulic piston 3 is pressurized and presses the plunger 9 with the force F1 against the end face N2 of the preform N (Fig. 2).
  • the counter-holder 12 exerts a counterhold force F2 on the bottom of the cup.
  • the pressure piston 9 performs a movement in the direction of the preliminary stroke of the drawing ring 14 in accordance with the ironing of the preform N, the pressure acting on the side wall N1 being produced by the forces F1 and F2 is maintained.
  • the material flow is favored so that material flows reliably into the profile 6 of the mandrel 5. This ensures excellent quality of the internal teeth.
  • Fig. 3 and 4 in the counter-holder 12 provide a material overflow 12.2.
  • the counter-holder 12 has in the direction of the preform N a pressure piece 12.1, which is also reduced in diameter in the direction of the preform N, so that between the pressure piece 12.1 and adapter 15, a gap is formed, in which the excess material can flow and thus as Material overflow 12.2 is used.
  • FIG. 5 it is also possible, in addition to the material overflow 12.2 provided in FIGS. 3 and 4, to arrange a further material overflow 12.3 at the end of the cylindrical side wall N1.
  • This can be the gap between serve the outer diameter of the plunger 9 and the inner diameter of the pull ring 14.
  • an increased axial pressure is exerted for calibrating in order to achieve a better filling and a higher accuracy of the internal toothing.
  • the possibly excess material can flow off as described above.
  • the increased pressure can now be applied, for example, by the pressure piston 9 being connected to a threaded ring G1 via an intermediate piece Z which has threads G at its outer diameter and which in turn is connected to the cylinder 3.1 and thus via the lower tool part 2 the press table 1 is supported.
