Definitions
- the invention relates to a forging machine with at least two counter-acting forging dies, which run lengthways in a forging box, each with its own mechanical linear actuators and preferably Have stroke position adjustment devices. (see e.g. US-A-4 430 881).
- Eccentric drives are used, in which the interaction of the Eccentrically rotatable sliding blocks and the sliding blocks receiving Conrod heads of the forging rams rotate the eccentric in lifting movements the forge stamp will be converted.
- the one forging Forging forces that occur therefore strain the Eccentric shafts on bend, so that these eccentric shafts accordingly must be dimensioned and stored, which means increased construction costs brings itself.
- the forging stamp is used to adjust the stroke position to provide special adjustment housing for the eccentric shaft bearing, whereby the machine frame because of the necessary bearing eyes in its rigidity is weakened and due to the displacement of the eccentric shaft center at Adjust a suitable eccentric shaft drive to compensate for this offset is required.
- the invention is therefore based on the object of a forging machine to create the type described above, which is characterized by its new drive concept and the associated high rigidity and simplified design.
- the invention solves this problem in that the lifting drives from a swash plate drive with one in the forging box around one to the respective forging punch axis parallel offset wobble axis can be rotated and driven, but is non-displaceable stored swash plate and one assigned to the swash plate, ball joint like on the swashplate facing end of the associated forging die supported thrust washer, where preferably the forging stamp over compression springs in the sense of a non-positive Connection of swash plates and pressure plates can be pressurized are.
- By rotating the eccentric relative to the forging punch axis Swashplate will depend on the forging die Swashplate bevel and the eccentricity a stroke with one of the Swashplate speed imposed on corresponding frequency, which Lifting movement is used to form the workpiece.
- the forging forces that occur are essentially directly from the forging stamp to the thrust washer transfer the swash plate, which leads to pure pressure loads and at simplified support conditions, increased machine rigidity brings. There is a non-positive between the swash plates and pressure plates Working together through suitable loads on the forging stamp is ensured.
- Compression springs are expediently used for this purpose, for example hydraulic cylinders connected to a pressure accumulator, which hold the pressure disks and press the swash plates together and their mutual Prevent taking off.
- the swash plate sits with a stub shaft rotatable, but axially immovable in an axially adjustable bearing sleeve supported in the machine box, so that through a longitudinal adjustment of the bearing sleeve independent of the actual one Stroke of the forging stamp a change in stroke position takes place because of the axial change of position of the swash plates also the pressure plates and thus the Forge stamps can be adjusted in their axial position.
- the bearing sleeve allows In addition, a stable drum disc bearing, with bending loads here too are largely avoided.
- the bearing sleeve could be axially adjustable in the machine box in any suitable manner be used, but especially a screw drive for Longitudinal adjustment is suitable, in which the bearing sleeve with the external thread in one Rotating but axially fixed locking nut supported in the forging box intervenes, which is assigned a rotary drive.
- a screw drive for Longitudinal adjustment is suitable, in which the bearing sleeve with the external thread in one Rotating but axially fixed locking nut supported in the forging box intervenes, which is assigned a rotary drive.
- the rotary drives each include a drive gear, which drive gears with one mounted on the forging box rotatable around the pass axis Interacting with the central wheel is a common one without great difficulty Stroke position adjustment of all forging stamps.
- the swash plate can be driven in many different ways, for example the swash plate can be driven via a toothed belt drive and forms with one Circumferential ring gear of a toothed belt pulley, which swash plate drive can be accommodated in the forging box to save space and is simple Use of appropriate gear ratios to achieve the desired one Swashplate speed allowed.
- the swashplate drive as a lifting drive is not only suitable for forging machines with a standing forging box, but also for forging machines, which are used as rotary kneaders, the then Forge box rotatable and drivable around the pass axis in a machine frame is stored.
- the linear actuators and the stroke position adjustment devices are arranged or supported on the forging box changes to their mode of operation is nothing due to the rotating bearing of the forging box and also the common stroke position adjustment and / or the common one Swashplate drive are retained when the respective drive wheels parts of epicyclic gears.
- a forging box 1 In a forging box 1 are in radial recesses 2 against each other acting forging stamp 3 guided longitudinally at their radially inner ends Pick up forging tools 4.
- swash plate drives 5 are provided, each of which in the forging box 3 offset by a parallel to the respective forging punch axis S.
- Swash axis T rotatable and drivable swash plate 6 and one of the Swashplate 6 associated, via a spherical bearing body 7 and spherical bearing shell 8 like a ball joint on the swashplate facing Front side of the associated forging punch 3 supported thrust washer 9 consist.
- the swash plates 6 are rotatable but axially with a stub shaft 12 immovably supported in an axially adjustable in the machine box 1 Bearing sleeve 13, which in turn with an external thread 14 in a rotatable, however axially displaceably engages in the forging box 1 supported adjusting nut 15, the adjusting nut 15 can be rotated via a rotary drive 16, the from a worm 17 and one of the adjusting nut 15 on the outer circumference formed worm gear ring 18.
- the screw 17 is with a Drive gear 19 connected, which drive gears 19 via intermediate wheels 20 with one on the forging box 1 about the forging axis A and comb driven central wheel 21.
- Toothed belt drive 22 To drive the swash plate 6 is a toothed belt drive 22, the rotating one Toothed belt 23 as a circumferential ring gear 24 of the swash plate 6 a toothed belt pulley with a seated on a parallel bevel gear shaft 25 Toothed belt pulley 26 connects.
- a small bevel gear sits on the bevel gear shaft 25 27, the one on the forging box 1 coaxial to the forging axis
- a rotatable and driven large bevel gear 28 meshes.
- a drive this Large bevel gear 28, for example via a pulley 29, therefore leads for driving the toothed belt drive 22 and thus for swash plate rotation and for the lifting movement of the forging stamp 3.
- FIG. 3 shows a similar forging machine 1, with parts remaining the same with the same reference numerals are provided, only in this machine the forging box 3 is rotating and drivably mounted in a machine frame 30 and can only with a a drive wheel 31 indicated drive around the forging axis A in rotation are offset so that the forging machine can be used as a rotary kneading machine is cash. Since the swash plate drives 5 and the stroke position adjustment devices arranged and supported together with their drives on the machine box the functions of lifting drives and stroke position adjustment devices remain unchanged and can also with a simultaneous rotation of the forging box be used unimpaired.
