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.
  • 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.
  • a generic ring rolling device for expanding a ring blank is in the CH 706 844 A1 described. It comprises a pressing element, a plurality of rotatably mounted mandrels, around which in each case a ring blank can be stored, and a rotatable revolver drum in which the mandrels are rotatably mounted. By rotating the revolver drum, the mandrels are 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 respective 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 turret drum per mandrel, for example, two roller bearings and at least two rotatably mounted support rollers, which support the mandrel in the direction of Revolvertrommelcoolachse out, so that the mandrel is located during rolling between the support rollers and the pressing member.
  • 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 rotation axis, wherein the mandrel rolls on its support rollers.
  • the ring rolling device has the advantage that both the feeding of the ring blank into 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 good rolling precision can be achieved.
  • a disadvantage of this known ring rolling device consists in the complexity of the device due to the many supporting rollers and their storage, which also has a negative influence on the rigidity of the system, and the relatively large masses to be moved, which are also caused by the supporting rollers.
  • the present invention is therefore based on the object to simplify a ring rolling device of the generic type constructive.
  • the achievable rolling precision should be improved as much as possible, moving masses should be kept as low as possible and the rigidity should be increased as much as possible.
  • a ring rolling device for expanding a ring blank comprises a pressing element, a rotatably mounted mandrel having a first end portion, a second end portion and therebetween a central part, around which the ring blank is storable, and a feed arrangement, in in that the mandrel is rotatably mounted with its first end part in a first rolling bearing and with its second end part in a second rolling bearing so that the middle part of the mandrel is exposed for supporting the ring blank.
  • the mandrel to the pressing element now and then moved away from it, wherein between the mandrel and the pressing element, a decreasing roll gap is formed, in which the ring blank is rolled.
  • the second rolling bearing is arranged axially fixed in the Zustellan eleven and the mandrel is axially movably mounted relative to the second rolling bearing, so that the second end portion of the mandrel from the second rolling bearing is pulled out or inserted into this.
  • the first rolling bearing in the feed arrangement is arranged axially fixed and the mandrel is mounted axially movable relative to the first rolling bearing.
  • the pivot bearing of the mandrel in axially fixed bearings is structurally less expensive than the storage on different types of bearings and in addition to support rollers.
  • less mass must be moved both during the movement of the delivery arrangement as well as the insertion of the mandrel through the ring blank and insertion into the second rolling bearing or vice versa when pulling out the mandrel again.
  • the latter is the case because the bearings themselves are axially fixed and only the mandrel itself axially, that is to say in its longitudinal direction, must be moved. This allows a high speed when feeding and ring rolling of ring blanks in the machine cycle.
  • the first and the second rolling bearing are designed as tangentially movable bearings, in particular spherical roller bearings or self-aligning ball bearings.
  • Spherical roller bearings and self-aligning ball bearings withstand high radial and axial loads and are well suited to compensate for misalignments. Moreover, they are relatively compact.
  • axially fixed sleeve-shaped bushes for receiving the mandrel are rotatably mounted in the first and in the second rolling bearing.
  • the bushes allow easy insertion of the mandrel in the bearings.
  • the bushings are arranged tiltable relative to the axis of rotation of the first and the second rolling bearing, wherein expediently the tiltability of the bushings is limited by stops. This allows a safe insertion of the mandrel in the rolling bearing or their sleeves.
  • the bush arranged in the second rolling bearing advantageously has a funnel-shaped insertion bevel.
  • the mandrel is advantageously formed conically or rounded at its front end on the second end portion.
  • the feed arrangement in an advantageous embodiment variant has a preferably adjustable stop element for the front end of the mandrel 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 stop element partially protrudes into the second rolling bearing and is formed with a feed line opening into the interior of the second rolling bearing for a cleaning and / or cooling agent.
  • the cans can be easily cleaned and / or cooled at times when no mandrel is stored in them or the mandrel is at least partially pulled out.
  • the stop element is rotatably mounted. As a result, the wear due to an adjacent, rotating mandrel can be significantly reduced.
  • the feed arrangement expediently comprises an alternative stop element for a stop collar on the first end part of the mandrel for positioning the mandrel in its longitudinal direction.
  • the alternative stop element is formed by the rotatably mounted in the first bearing sleeve. This design of the stop element is structurally particularly simple.
  • the feed arrangement is a rotatable turret drum, wherein the turret drum is arranged relative to the pressing member so that by turning the turret drum between the mandrel and the pressing member, a decreasing nip is formed.
  • the storage of the mandrel on a revolver drum is structurally favorable and allows a high machine cycle.
  • the revolver drum comprises two spaced apart, rotationally rigidly interconnected, disc-like drum parts, in which the first roller bearing and the second roller bearing for the mandrel are arranged axially fixed.
  • disc-like drum parts of the mandrel can be stably and rotatably mounted on both sides of the ring blank supporting middle part.
  • the first and the second rolling bearing are each interchangeably mounted in the drum parts as a whole.
  • the ring rolling device can be quickly and easily converted to another mandrel diameter.
  • At least the bushing arranged in the second rolling bearing has a form-locking element, preferably designed as an annular groove, for applying an assembly tool.
  • the second rolling bearing can be easily removed by means of the tool from the ring rolling device.
  • the ring rolling device has a preferably closed cooling system for the roller bearings and / or infeed arrangement.
  • 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 together with the mandrel adjustment device, makes it easy to store a ring blank around the mandrel.
  • a ring blank may be mounted around a mandrel at a first station, a ring blank rolled at a second station, and a ring blank from a mandrel at a third station be removed.
  • 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.

  • 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 collar 12 and 13 prevent during the ring rolling a lateral expansion of the ring blank 9.
