Definitions
- the invention relates to a method and a device for producing a workpiece with internal teeth, in particular a ring gear, according to the preamble of the first claim.
- Internal gears of this type are produced, for example, by pressure rolling.
- a cup-shaped preform is gem.
- DE 198 30 817 AI pressed by means of tapered rollers during a feed movement against a tool chuck, which has the outer profile of the internal toothing to be produced, and reduced in diameter, the preform rotating relative to the tapered rollers.
- the material of the cylinder wall area of the preform flows into the profile of the tool chuck, which creates the inner profile of the workpiece. Disadvantages are the high flexing work during the press-rolling process and the inadequate quality of the internal teeth.
- the object of the invention is to provide a method and a device for the energy-saving production of a workpiece with internal teeth, in particular a ring gear, which ensure a substantial increase in productivity with a high quality of the internal teeth with a relatively simple design of the device.
- the device for producing a workpiece with internal toothing in particular a ring gear for gears, has a mandrel with an outer profile corresponding to the internal toothing to be produced, as well as a forming tool which reduces the outer diameter of a cup-shaped preform during a feed movement, whereby material of the cylinder wall area into the outer profile of the thorn flows.
- a drawing ring is used as the forming tool, which ensures ironing of the cylinder wall area during a feed movement.
- an axially movable counter-holder In the direction of the underside of the bottom of the preform, an axially movable counter-holder is arranged such that it acts on the underside of the bottom of the preform with a counter-holding force during ironing.
- the counter-holder can have a circular pressure surface pointing towards the underside of the base, which acts essentially on the entire base region, or an annular pressure surface, which is adapted to the width of the cylinder wall of the preform and is essentially aligned with it and towards the edge region the bottom of the bottom of the preform acts.
- an axially movable pressure stamp In the direction of the end face of the cylindrical side wall of the preform, an axially movable pressure stamp is arranged such that it acts on the end face with a compressive force during the ironing.
- the pressure stamp can be moved axially during the ironing by a movement corresponding to the ironing length of the preform in the direction of the feed movement of the drawing ring.
- the axial stroke movement of the pressure plunger which takes place during the ironing is advantageously controllable as a function of its pressure force.
- the pressure ram is mounted so that it can move axially via a hydraulic piston.
- the device can advantageously be integrated into a hydraulic press consisting of a press table and a press ram.
- the mandrel is arranged axially fixed on the press table and on the mandrel, axially displaceable via a hydraulic piston, the pressure stamp is mounted.
- the drawing ring is preferably fixed to the frame and the counter-holder is preferably axially movable via a hydraulic piston.
- the pressure stamp is preferably designed as a cylindrical pressure sleeve.
- the distance of the pressure surface of the pressure stamp to the end surface of the mandrel, which is adapted to the length of the preform, can be set, for example, using spacer rings.
- the mandrel is rotatably supported when producing helical teeth.
- the workpiece is produced with internal teeth, in that a cup-shaped preform with a bottom and an essentially cylindrical side wall is reduced in its outer diameter over a mandrel which has the outer profile corresponding to the internal teeth to be produced, so that the material of the Cylinder wall area flows into the outer profile of the mandrel, wherein according to the invention the outer diameter is reduced by ironing by means of a drawing ring.
- axial compressive stresses are applied to the cylindrical side wall of the preform, so that the material flow into the profile of the mandrel is promoted.
- the axial Compressive stresses are preferably applied by a pressure stamp acting on the end face of the cylinder wall.
- a counterholder acts on the underside of the floor in order to avoid deformations in the floor area and to apply a counterholder force.
- the counterholder force of the counterholder and the force of the plunger should be controllable relative to one another in such a way that a material flow in the radial direction is ensured during the entire ironing process in order to completely fill the contour of the mandrel.
- the pressure stamp carries out an axial stroke movement corresponding to the ironing length of the preform in the direction of the feed movement of the drawing ring, which is regulated as a function of its compressive force.
- Fig. 1 Device with inserted preform before
- FIG. 2 device during ironing
- Fig. 3 device with inserted preform and material overflow in the counter holder in front of the
- the press base 1 has the lower tool part 2, which has a first hydraulic piston 3. At the
- Lower tool part 2 is axially fixed over a
- Stamp 4 of the mandrel 5 attached which has an outer profile 6.
- An ejector 7 runs in the center of the punch 4 and in the mandrel 5.
- the pressure punch 9 designed as a pressure sleeve is mounted on the hydraulic piston 3 via an adapter 8 so that it can move axially.
- the axial position of the Druckste pels 9 can be changed over distances 10 which can be attached between the adapter 8 and the plunger 9.
- the upper tool 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 also fixed to the press ram by means of an adapter 15.
- the cup-shaped preform N was inserted with the cylindrical edge N1 downward over the mandrel 5, so that the end face N2 points in the direction of the pressure stamp 9 and the underside of the base N3 in the direction of the counter-holder 12.
- the hydraulic piston 13 moves the counter holder 12 in the direction of the lower part of the tool until the counter holder 12 rests on the underside of the base N3.
- the drawing ring 14, which is fixed to the press ram P, moves in the preliminary stroke with the press ram P in the direction of the press table 1, at the same time the first hydraulic piston 3 is pressurized and presses the pressure ram 9 with the force Fl against the end face N2 of the preform N (FIG. 2).
- the counter-holder 12 exerts a counter-holder force F2 on the bottom of the cup.
- the plunger 9 executes a movement in the direction of the forward stroke of the drawing ring 14 in accordance with the ironing of the preform N, the pressure acting on the wall N2 being maintained by the forces F1 and F2.
- the material flow is favored so that material flows reliably into the profile 6 of the mandrel 5. This ensures an excellent quality of the internal teeth.
- the upper tool part 11 moves upwards and the workpiece is released from the mandrel 5 via the ejector 7, which is rotatably mounted with helical teeth.
- the counter-holder 12 has a pressure piece 12.1 in the direction of the workpiece N, which is also reduced in diameter in the direction of the workpiece N, so that a gap is formed between the pressure piece 12.1 and the adapter 15, into which the excess material can flow and which therefore acts as Material overflow 12.2 is used.
- FIG. 5 it is also possible to arrange a further material overflow 12.3 at the end of the cylindrical wall in addition to the material overflow 12.2 provided in FIGS. 3 and 4.
- the gap between the outer diameter of the pressure stamp 9 and the inner diameter of the drawing ring 14 can be used for this purpose.
- an increased axial pressure is applied for calibration in order to achieve better filling and a higher accuracy of the internal toothing. Any excess material can flow away as described above.
- the piston 3, which is guided in the cylinder 3.1 is in its lowest position.
- the increased pressure can now be applied, for example, by the pressure ram 9 being connected via an intermediate piece Z, which has a thread G on its outer diameter and is also connected to a threaded ring Gl, which in turn rests on the cylinder 3.1 and thus on the lower tool part 2 supports the press table 1.
