Definitions

  • the present invention relates to a ring rolling apparatus according to the preamble of independent claim 1.
  • a known variant for producing rings is first to forge a ring blank, which is then further processed by ring rolling.
  • the ring blank is mounted around a mandrel and then rolled between the mandrel and a forming roll.
  • the thickness of the ring blank is reduced and at the same time its circumference is increased, since no material is removed.
  • the nip between the mandrel and the forming roll must be continuously reduced, which can be done for example by a displacement of the mandrel to form the forming or vice versa.
  • the forming roller is formed so that its radius increases continuously, starting from a start zone against the rolling direction.
  • a constant reduction of the roll gap occurs at a constant spacing of the mandrel, whereby the ring blank is rolled to a smaller thickness.
  • four mandrels are mounted on a turntable, so that by rotating the turntable by 90 ° each of the next mandrel is rotated with the next previously arranged around it ring blank for forming roll back into the rolling position. This rotation is done exactly when the turntable faces the start zone of the forming roll where the ring blank is not yet in contact with the forming roll.
  • the rolling of the ring blank is only then by turning the forming roller, while the turntable is no longer rotating.
  • a disadvantage of this ring rolling device is that it requires a specially shaped forming roll.
  • the rolling of the ring blank must be carried out during exactly one revolution of the forming roll and the next ring blank must be brought into the rolling position at exactly the right time by a coordinated rotation of the turntable.
  • a ring rolling apparatus comprising a roller as a pressing member and a turntable with a plurality of rotatably mounted thorns around which are mounted to be rolled ring blanks.
  • the mandrels are movable towards the pressing element every now and then.
  • a shrinking roll gap is formed between the mandrel and the pressing element, in which the ring blank is rolled.
  • the mandrels in each case engage in a conical bore in a mandrel-roll pin rotatably mounted in the turntable and are fixedly connected at the top with a second mandrel-roll pin.
  • the present invention is therefore an object of the invention to provide a ring rolling device of the type mentioned, which allows a fast and accurate feeding and rolling of ring blanks.
  • a ring rolling device for expanding a ring blank comprises a pressing element, a rotatably mounted mandrel, around which the ring blank is storable, and a rotatable revolver drum in which the mandrel is rotatably mounted.
  • the revolver drum By turning the revolver drum, the mandrel is movable towards the pressing element from time to time.
  • the turret drum is arranged relative to the pressing member so that by rotating the turret drum between the mandrel and the pressing member, a decreasing rolling gap is formed, in which the ring blank is rolled during rotation of the turret drum.
  • the revolver drum for rotatably supporting the mandrel has at least two rotatably mounted support rollers which support the mandrel in the direction of the revolver rotating axis, so that the mandrel is located between the support rollers and the pressing element during rolling.
  • the inventive ring rolling device has the advantage that both the feeding of the ring blank in the rolling position and the rolling of the ring blank by the revolver drum is rotated towards the pressing element. By this rotation, first a roll gap is formed and the ring blank is brought into contact with the pressing element and then the rolling gap is reduced, whereby the ring blank is rolled between the mandrel and the pressing element, that is, the wall thickness of the ring blank is reduced.
  • the at least two rotatably mounted support rollers enable support of the mandrel during rolling to accommodate the rolling forces over a desired mandrel length and rotation of the mandrel during rolling about its mandrel axis of rotation. In this way, a high rolling precision can be achieved. In addition, the mandrel only needs to be placed on the support rollers, which can be done very quickly.
  • the axes of rotation of the mandrel and the support rollers and the revolver rotating axis and, if the pressing member is a drive roller whose axis of rotation are preferably parallel, but this is not essential.
  • the turret drum comprises two spaced apart, rotationally rigidly interconnected, disc-like drum parts, in each of which a part of the mandrel is rotatably mounted, so that a central part of the mandrel is exposed between the two disc-like drum parts for supporting a ring blank.
  • disc-like drum parts of the mandrel can be stably and rotatably mounted on both sides of the ring blank supporting middle part.
  • the disk-like drum parts for rotatably supporting the mandrel each have at least two rotatably mounted support rollers which support the mandrel in the direction of the revolver rotation axis, so that the mandrel is located between the support rollers and the pressing element during rolling.
  • the at least two support rollers allow a support of the mandrel on both sides of the central part for receiving the rolling forces over a desired mandrel length and a rotation of the mandrel during rolling about its mandrel rotation axis.
  • each support roller has a support flange for supporting the mandrel.
  • the mandrel is then only on the support flanges, allowing for easier placement.
  • the support flanges are each arranged at one end of the support rollers and serve as lateral guides for the ring blank.
  • the ring blank can thus be stabilized during rolling without additional components.
  • the mandrel is rotatably mounted in the revolver drum in at least one rolling bearing.
  • Rolling bearings also provide good support of the mandrel for receiving rolling forces over a desired mandrel length and rotation of the mandrel during rolling about its mandrel axis of rotation.
  • Rolling and support rollers can also be combined.
  • the revolver drum has a stop for positioning the mandrel in the longitudinal direction of the mandrel. This allows accurate positioning of the mandrel and the ring blank thereon for rolling and is particularly important if the mandrel and / or the pressing element has a profiling to be transmitted to the ring blank.
  • the inventive ring rolling device on a Dornverstell noticed for adjusting the mandrel in the longitudinal direction of the mandrel.
  • This makes it possible, by retracting the mandrel, feeding a ring blank into a loading position and again pushing the mandrel and pushing through the mandrel through the present in the loading position ring blank this ring blank in a simple manner around the mandrel around or store.
  • the finished rolled ring can be removed again by withdrawing the mandrel from the mandrel.
  • the ring rolling device according to the invention preferably has a ring blank feed device with which ring blanks can be supplied individually to a point at which the mandrel can be pushed through the supplied ring blank, that is to say the loading position mentioned above. This allows together with the Dornverstell worn in a simple way, the storage or placing a ring blank around the mandrel.
  • a ring blank may be stored around a mandrel at a first station, a ring blank rolled at a second station, and a ring blank removed from a mandrel at a third station.
  • the rolling throughput can be increased significantly, that is, in a shorter time more ring blanks can be rolled into rings.
  • the ring rolling device can be attached, for example, to a cold or hot forming machine.
  • the advantage can be exploited so that the still warm ring blanks produced by the hot forming machine can be rolled directly with the ring rolling device.
  • An additional warming of the ring blanks can be omitted for a hot ring rolling.
  • inventive ring rolling devices can be used both for a hot ring rolling and a cold ring rolling.
  • cooling of the components of the rolling device may optionally be provided.
  • the inventive ring rolling device has a drive device for driving the pressing element, so that the ring blank is rotatable during rolling by the movement of the pressing element.
  • a drive device for driving the pressing element so that the ring blank is rotatable during rolling by the movement of the pressing element.
  • This makes it possible to rotate the ring blank on the rotatably mounted mandrel by means of the pressing member during rolling several times, wherein the ring blank is rolled to a smaller thickness with each rotation.
  • a greater reduction in thickness and a more uniform, material-sparing rolling can be achieved.
  • Particularly advantageous is a - depending on the size of the ring blank and the desired wall thickness reduction - three to thirty times, in particular eight to twelve times, turning of the ring blank during rolling proven.
  • the pressing element is a rotatably mounted drive roller.
  • a drive roller can, for example, be driven continuously by means of a motor and in turn transmit its rotational movement to the ring blank mounted around the mandrel as soon as it comes into contact with the drive roller.
  • the turning of the drive roller can take place continuously and at constant speed, and a return of the pressing element after rolling is dispensed with.
  • an inventive ring rolling device comprises a pressing element as a drive roller 1, which has at its periphery a rolling surface 11 which is bounded on both sides by a collar 12 and 13 respectively.
  • the collars 12 and 13 prevent during the ring rolling a lateral expansion of the ring blank 9, as best of the FIGS. 9 and 10 seen.
  • the drive roller 1 is over a Shaft 14 is rotatably mounted on a bearing plate 15 and is driven by a drive device 10.
  • the bearing plate 15 is mounted, for example via three rail gripping elements 151, 152 and 153 in the direction of a revolver rotation axis 39 adjustable above and below each of a rail 81 and 82, which in turn are firmly anchored in a machine frame 8.
  • an adjusting spindle 154 By means of an adjusting spindle 154, the bearing plate 15 and thus the drive roller 1 mounted thereon can be adjusted in the direction of the roll gap, whereby the size of the roll gap can be adjusted at its narrowest point.
  • the adjusting spindle 154 has for this purpose, for example, an external thread which engages in an internal thread in a passage 83 through the machine frame 8, through which the adjusting spindle 154 is arranged.

  • Fig. 2 can be seen that in the present revolving drum 3 five mandrels 2 evenly distributed, based on the revolving revolver axis 39 at an angular distance of 72 °, are rotatably mounted.
  • the turret drum 3 is rotatably mounted on the machine frame 8 via a shaft 33 and is rotated by means of a drive device 30, for example an electric drive or servomotor.
  • the ring rolling device shown has a ring blank feed device 5 on.
  • the ring blank feed device 5 is designed to supply ring blanks 9 individually to a point at which a mandrel 2 can be pushed through the supplied ring blank 9, that is to say a loading position.
  • the ring blank feed device 5 has a supply chute 51 in which a plurality of ring blanks 9 can be stored.
  • the storage chute 51 is provided at its lower end with an opening through which passes a ring blank 9 due to gravity directly to the loading position.
  • a hinged retaining element 52 which is held in a retaining position by means of a spring element 54 acting on a cam follower 53, in which it holds the ring blanks 9 in the supply shaft 51.
  • the cam follower 53 is simply acted upon by means of a control cam 55 which is rotatably mounted about the revolver rotating shaft 39 and counter to the spring force.
  • the ring rolling device has a mandrel adjusting device 4 for adjusting the mandrel 2 in the longitudinal direction of the mandrel 2. Since the bearing of the ring blank 9 around the mandrel 2 around and the removal of the rolled ring 90 from the mandrel 2 takes place at two different locations, namely on the one hand directly below the supply chute 51 and on the other hand approximately after a rotation of the revolving drum 3 by about 150 ° the Dornverstell issued 4 two separate adjusting 41 and 42 which are fixed to the machine frame 8.
