Definitions
- the invention relates to a circular kneading machine for round forging rod-shaped or tubular workpieces, with a around the pass axis of the Workpiece rotatably and drivably mounted in a machine frame ring-shaped Forge box, the one acting in radial recesses against each other and with simultaneous rotation of the forging box via a lifting drive Forges stamps.
- the invention is therefore based on the object of a circular kneading machine to create the type described, in which the stroke position of the forging stamp can be adjusted rationally and also the larger stroke position adjustments allowed during a forging process.
- the invention solves this problem in that the forging stamp in itself known manner two parts connected to each other adjustable by screw, one drive-side, rotatable upper part in the forging box and one tool-side, rotatably guided lower part in the forging box, the upper part is a gear with a non-rotatable but axial on the upper part slidably seated and rotatable in the forging box, but axially fixed mounted ring gear and one rotatably mounted in the forging box Drive gear belongs to which drive gears are part of an epicyclic gear are.
- the gearbox for the drive connection of the drive gear and the ring gear is preferably a worm gear, the The worm wheel forms the ring gear and the one that interacts with the worm wheel Worm is connected to the drive gear.
- Forging stamps each assigned their own epicyclic gear can be adjust the forging stamps differently in pairs in their stroke position, by driving the associated gears differently from each other be what, for example, when forging tubular workpieces over mandrel is useful to by forging a slightly oval cross-section to prevent the workpiece from being forged onto the mandrel.
- the stroke position adjustment device can be used with any suitable device Combine the linear actuator if the rotatable upper part of the stamp is rotatable is taken care of.
- a linear actuator an eccentric drive is provided for the forging stamp and the Forged stamp for drive connection on the eccentric facing end of the upper part a sliding surface for a seated rotatably on the eccentric Form the sliding block, whereby the upper part and sliding block are non-positive with each other are connected and on the forging box on the one hand and on flange approaches of the
- supported compression springs pressurize the forging dies and press the top parts with their sliding surfaces onto the sliding blocks.
- This lifting drive does not only offer the advantages of an eccentric drive used for the linear actuator, but the forging die can be used because of the missing form fit between the upper part and sliding block next to the transverse displacement can also be twisted, making it relatively rotatable without additional Coupling parts or the like.
- the stroke position adjustment also during operation is feasible.
- the non-rotatable lower part due to the non-rotatable lower part, the proper Use of the forging tools on the one hand and the perfect pressurization guaranteed on the other hand by the compression springs, whereby by a corresponding adjustment of the spring travel or the preload Pressure springs may require changes in pressure balance.
- a circular kneading machine 1 for round forging rod-shaped or tubular Workpieces consists of a machine frame 2, in which an annular Forging box 3 can be rotated and driven about the through axis A of the workpiece stores.
- the forging box 3 has radial recesses 4 for receiving counteracting and at the same time stroke movable with the forging box rotation Forging stamp 5 on the workpiece side with a forging tool 6 equipped and on the side facing away from the workpiece with an eccentric drive 7 trained lifting drive are equipped.
- the eccentric drive 7 comprises the forging dies 5 assigned in ring walls 8 of the forging box 3 mounted eccentric shafts 9 with eccentrics 10, on which with the Forging dies 5 interacting sliding blocks 11 rotatably sit.
- the Forging dies 5 form for the drive connection on the eccentric facing A sliding surface 12 for the sliding blocks 11, sliding block 11 and Forging stamps 5 are connected to each other in a purely frictional manner and the Forging stamp 5 by compression springs 13, preferably hydraulic springs the forging box 3 on the one hand and the flange lugs 14 of the forging stamp 5 support on the other hand, pressurized and with their sliding surfaces 12 be pressed against the sliding blocks 11.
- the forging dies 5 are over Straight guides 15 in the forging box 3, so that when the eccentric rotation the forging dies 5 via the sliding blocks 11 a lifting movement is forced radially to the pass axis A.
- a planetary gear 16 For driving the eccentric shafts 9 is a planetary gear 16 made of one on the outer periphery of the forging box 3 rotatable and driven, for example, via a pulley 17 mounted sun gear 18 and each assigned to the eccentric shafts 9 Planet gears 19 are provided.
- the forging stamps have 5 two parts which are connected to one another in a screw-adjustable manner, one on the drive side in the forging box 3 rotatably guided upper part 51 and a tool-side, in the forging box 3 rotatably guided lower part 52 so that a rotation of the upper part 51 to a change in length due to the screw connection of the forging punch 5 and thus leads to the stroke position adjustment.
- For Rotation of the upper part 51 belongs to this a gear 20, the one on Upper part 51 rotatably, but axially displaceable and in the forge box 3 rotatable, but axially fixed gear ring 21, for example a worm wheel, and a worm 22 meshing with the worm wheel as well as an axis of rotation D rotatable about an axis of rotation D parallel to the passage axis A.
- Forge box 3 mounted drive gear 23 for the rotation of the screw 22 has.
- the drive gears 23 are part of an epicyclic gear 27 and comb with a coaxial to the pass axis A, on the forging box 3 and drivably mounted central wheel 24.
- the upper part 51 is also driven by the drive gears 23 the forging punch is twisted and the stroke position is adjusted. Since the upper part 51 forms the sliding surface 12 and the lower part 52 the Has flange approaches 14, the upper part without affecting the drive connection be twisted relative to the sliding block and the compression springs 13 can attack the lower part 52 guided in a rotationally fixed manner.
- the drive gears 23, 231 of the gear 20 of two opposing forging dies 5 each have their own epicyclic gear 27, 271 with central wheel 24, 241 be assigned so that by different drive of the two central wheels 24, 241 the stroke positions of the forging stamps 5, which are offset in relation to one another be changed unequally and the circular kneading machine 1 as a result Pipe forging must be coordinated using a mandrel.
- the forging box 3 is only one by means of a pulley indicated drive 26 rotated, can thus be independent of this rotation of the forging box via the rotary drive 16 of the eccentric drive 7 for operate the forging stamp 5, whereby the forging stamp 5 at the same time Rotation around the pass axis A its required for forging Carry out lifting movement.
- the forge box rotation on the one hand and the Lifting movement of the forging stamp on the other hand can then also be done via the Central wheel 24 or the central wheels 24, 241, the drive gears 23 or 23 and 231 and the gears 20 a change in length of the forging stamp 5 and thus a stroke position adjustment of the forging tools 6 is superimposed so that kneading is not only possible with different tool positions, but also with changing tool positions during the forging process is possible.
