Definitions

  • the invention relates to a profiling machine with one or more pairs of forming rollers arranged one behind the other in the feed direction of a workpiece, each of which is mounted in tool stands by means of working shafts, in addition to which a drive with a gear block and between the latter and the ends of the working shafts facing it are pushed together in their length and pulling apart adjustable cardan shafts and couplings are provided as detachable connections between the cardan shafts and the working shafts, a coupling frame or carrier being arranged between the respective tool frame and the associated gear block, on the side facing the gear block the cardan shafts and on the side facing the tool frame the releasable couplings for the working shafts are arranged, and wherein the bearing is adjustable in height at least the upper coupling shaft.
  • Profiling machines are known and allow the production of profiles with relatively complicated cross sections from strips or sheet metal strips with high accuracy and high speed.
  • Profiling machines When changing from a product to a product with a different cross-section, however, there is a loss of time due to the change of the forming rolls, which must first be disengaged and removed and replaced with new sets of rolls, which must then be engaged again.
  • JP-A-59 218 221 which is considered to be the closest prior art, a profiling machine of the type mentioned is known, in which the block containing the forming rollers must be removed from the coupling position in the longitudinal direction of the drive shafts before it can be replaced can be lifted off and replaced in the reverse order with a new tool set.
  • the working shafts and their scaffolds must therefore first be moved on their substructure until the couplings are released before a tool change can be carried out.
  • DE-A-24 39 017 aids are known which are intended to facilitate the replacement of pairs of forming rollers. Above all, the new adjustments and adjustment work that are necessary when replacing such forming rolls are to be avoided.
  • This aid consists in a fixation and support device, which can be supported on the machine part, for a pair of forming rollers, so that the replacement of the individual forming rollers is also time-consuming and difficult. Above all, considerable personnel expenditure is required.
  • a profiling machine was therefore created in which, in order to shorten changeover times in a roll stand, two pairs of forming rollers arranged one above the other are provided for different profiles.
  • the number of profiles of different cross sections that can be produced with this profiling machine is limited to a minimum.
  • the solution to this problem is that the coupling frame or the coupling carrier, together with the coupling half facing it, can be moved or displaced transversely to the feed direction of the workpiece and transversely to the working direction of the forming rollers from the tool frame and the coupling half facing this, that on the bearing of the coupling shaft or a sensor, sensor, switching element or the like on the tool frame. is provided for automatic and automatic adjustment to the respective height of the counter-coupling half of the associated working shaft and that the displacement drive for the coupling frame is controlled in such a way that the displacement movement for engaging or its last section only after the height adjustment of the coupling half of the coupling frame or carrier the coupling half of the tool frame is done.
  • the complete roll tool which can consist of one or more pairs of forming rolls arranged one behind the other, can be quickly and fully automatically changed in one or more tool stands arranged one behind the other by exchanging one tool frame for another after uncoupling, without any time have to be postponed beforehand so that unproductive downtimes that occur during the changeover are reduced to a minimum.
  • gear block and the coupling frame or the like are fastened to a common gear carrier, which is mechanically adjustable by means of a drive in guides, for example sliding guides, transversely to the feed direction of the workpiece, in particular at right angles to the feed direction.
  • guides for example sliding guides
  • the distance between the gear block and clutch remains unchanged and it is only necessary to compensate for the changing altitude, especially of the upper clutch on the coupling frame or carrier, by means of the cardan shafts located between the gear block and coupling frame.
  • a single drive is sufficient for the transverse displacement.
  • the like can be used to move the gear block with the coupling frame.
  • a motor-driven spindle can be provided, which also makes it possible to first carry out a first part of the displacement path when engaging, before then adjusting the height of those located in the coupling structure or on the coupling carrier Coupling half is carried out on a coupling half on the forming rollers which may be at a different height due to the tool change, after which the final displacement movement of the gear block and the coupling frame or the like. is feasible in the working position. This shifting movement of the gear block can therefore take place in two steps.
  • a modified embodiment in which the movable masses are reduced may consist in the fact that the gear block and the coupling frame or the like. are each attached to their own support or bearing and only the coupling frame or the like. or the like, the coupling frame.
  • load-bearing beams by means of a drive e.g. a motor-driven spindle, preferably in guides, is mechanically adjustable transversely to the feed direction of the workpiece. This is possible without any problems because the length of the cardan shafts can be adjusted in a known manner by pulling them apart and pushing them together, which also favors the height adjustment of the individual couplings.
  • the fully automatic adjustment of the height of the coupling halves facilitating embodiment of the invention can consist in that as a sensor or sensor on the coupling frame or the like. or, if appropriate, an arm, preferably oriented parallel to the axis of the coupling shaft, is provided on the tool frame, which fixes the coupling half in its coupling position to the counter-coupling half at the end of the height adjustment with a counter stop. It can thus be effected in a purely mechanical way by means of a stop arm and a counterstop that the height adjustment of the one coupling half is ended at the right moment, namely when the coupling halves have arrived in the same position for engaging.
  • An advantageous embodiment can consist in that the counter stop for the arm is one of the coupling halves.
  • the stop arm coupling frame or the like. attached, the coupling half located on the tool frame can be its counter-stop.
  • a working cylinder in particular a pneumatic cylinder, or a servomotor can be provided as the drive for the height adjustment of the coupling.
  • Such drive means can namely be stopped by a mechanical stop even when they are still under pressure or current, so that no great control effort and the like is required for the automatic alignment of the two coupling halves to one another in their coupling position.
  • both the upper and the lower bearing of the drive shafts on the coupling frame or the like. can be mechanically adjustable in height so that the couplings for a pair of forming rollers can be adapted to the working shafts.
  • One of the coupling halves in particular that of the sliding coupling frame or the like. worn coupling half, in turn - or the like - compared to the coupling frame. - Be axially displaceable against a restoring force. This applies in particular to couplings whose halves interlock positively. If the two halves do not yet fit into each other when engaging, because they are offset in the direction of rotation, one half of the coupling can initially dodge. It is then sufficient to briefly start the drive in order to bring the matching parts, for example coupling pins and coupling perforations or the like, into alignment, so that the restoring force then ends the engagement movement of the displaceable coupling half.
  • the restoring force for the preferably on the coupling frame or the like. located coupling halves can be generated by compression springs and both coupling halves located on the coupling frame can be axially displaceable against spring force.
  • the fully automatic tool change and in particular also the fully automatic re-coupling can be promoted and improved in that sensors are provided for monitoring the coupling process, which block the drive until the end of the coupling process. This ensures that the drive of the profiling machine and the forming rollers can only start again when all the couplings are really engaged and ready for operation. Further embodiments of the invention are the subject of claims 11 and 12.
  • a profiling machine designated as a whole by 1, has, in a known manner, either one or a plurality of pairs of forming rollers 2 in the feed direction of a workpiece, which pairs are formed in a known manner from matching forming rollers 3 and 4, the outer contours of which in their working area are to be formed on them Generate cross-section of the workpiece.
  • These forming roller pairs 2 are by means of Working shafts 5 are each mounted in a tool frame 6, which is constructed on a tool carrier 8 which is detachably fastened to the profiling machine 1 or its base frame 7, a lifting device (not shown in more detail) for lifting and exchanging these tool frames 6 being provided.
  • the tool carriers 8 are centered on the machine base frame 7 by means of centering bolts 9 which match the corresponding perforations.
  • centering bolts 9 which match the corresponding perforations.
  • other positioning and / or centering devices could also be provided.
  • the tool frame 6 consists of a lower bearing housing 10, columns 11 embedded therein on both sides and upper bearing housings 12 and a yoke 13, each of which carries an adjusting screw 13a which determines the position of the respective upper bearing housing 12.
  • the bearing housings 10 and 12 contain the bearings for the working shafts 5 of the lower and upper forming rollers 4 and 3.
  • the distance between the lower and upper working shaft 5 and thus the position of the upper bearing housing 12 is determined by the diameter of the upper forming roller 3 and is different from pair of forming rollers to pair of forming rollers.
  • the working shafts 5 also carry counter-coupling halves 14 of couplings 15 at their ends facing away from the forming rollers 3 and 4.
  • a coupling frame 18 is provided between the respective tool frame 6 and the associated gear block 16, on the side facing the gear block 16 the drive shafts 17 and on the side facing the tool frame 6 the releasable couplings 15 for the working shafts 5 are arranged.
  • the coupling frame 18 a different type of coupling carrier or holder could also be provided.
  • the gear block 16 can now be moved together with the coupling frame 18 transversely to the direction of advance of the workpiece and transversely to the working direction of the forming rollers 3 and 4 to release the couplings 15 away from the tool frame 6 in the direction a of the double arrow Pf 1.
  • the height of the mounting of the upper propeller shaft 17 on the coupling frame 18 can be adjusted mechanically, so that the coupling half 19 of the coupling 15 assigned to it can also be adjusted in height.
  • a sensor to be described in more detail for automatic and automatic adjustment to the respective height of the mating coupling or coupling half 14 of the associated working shaft 5 is provided on the coupling frame 18.
  • the shift drive for the gear block 16 with the coupling frame 18 is now controlled such that the shifting movement or its last section in direction b of the double arrow Pf 1 for coupling takes place only after the height adjustment of the coupling on the coupling frame. With a sufficiently long sensor, either the height adjustment and then the complete displacement movement of the gear block 16 could take place.
  • the drive group consisting of gear block 16 and coupling frame 18 is shifted in the direction b of the double arrow Pf 1 to point b1, where the shifting movement is interrupted and the upper bearing housing 18a of the coupling frame 18 is adjusted in its altitude until this vertical adjustment movement is limited and ended by the sensor, which will be described in more detail. If the coupling halves 19 and 14 are at the same height, the drive group can be shifted further from b1 to b in order to end the engagement of the coupling.
  • the gear block 16 and the coupling frame 18 are fastened on a common gear carrier 20, which is mechanically adjustable by means of a drive, in the exemplary embodiment of a motor-driven spindle 21, in or on guides 22 transversely to the feed direction of the workpiece.
  • the drive motor 23 for the spindle 21 can be seen in FIG. 1.
  • an arm 25 oriented parallel to the axis of the coupling shaft 24 is provided in the exemplary embodiment on the coupling frame 18, but could also be reversed on the tool frame 6, and which, together with a counterstop, ends the height adjustment of the two coupling halves in their coupling position.
  • the height adjustment of the coupling half 19 means the corresponding height adjustment of this arm 25 until it comes to rest on its counter-stop, in the exemplary embodiment of the coupling half 14.
  • a preferably pneumatic working cylinder 26 is provided for height adjustment of the upper coupling half 19, but this could also be accomplished by a servomotor.
  • Fig. 2 it can be seen that the one coupling half, in the exemplary embodiment the coupling half 14 located on the working shaft 5, perforations 27 and the other coupling half coming into operative connection therewith, in this case the coupling half 19 having coupling pins 28 fitting into these perforations 27, which taper somewhat at the end to simplify the coupling process. Nevertheless, it could happen that the perforations 27 and the coupling pins 28 are offset against one another in the direction of rotation when engaging in such a way that the coupling process does not initially take place.
  • one of the coupling halves in this case the coupling half 19 carried by the coupling frame 18, is axially displaceable against a restoring force, the restoring force for the axially adjustable coupling half 19 each being generated in the exemplary embodiment by a compression spring 29.
  • both coupling halves 19 of the coupling frame 18 can dodge axially against the force of such a compression spring 29 if the coupling pins 28 do not hit the holes 27 when performing the coupling movement, this case in the drawing on the lower Coupling is shown.
  • sensors can be provided for monitoring the engagement process, which block the drive for the transmission block 16 until the coupling process has ended. If the pins 28 are somewhat offset relative to the perforations 27, the drive can be briefly rotated until the pins can enter the perforations.
  • the changing of the forming roller pairs can therefore take place fully automatically in this profiling machine 1 in the following way:
  • the drive group comprising the transmission block 16 and the coupling frame 18 located on the transmission carrier 20 is moved in the direction a by means of the spindle 21 driven by the motor 23 on the guides 22 according to the double arrow Pf 1.
  • the coupling pins 28 are pulled out of the perforations 27 in the coupling halves 14 so that the tool carrier 8 carrying the tool frame 6 can be lifted off by means of a lifting device.
  • This lifting device can be provided with access to a tool magazine in which the complete tool frame 6 with tool carrier 8 can be stored.
  • the same lifting device can take another complete tool from the same tool magazine and place it on the base of the profiling machine 1, the positioning and centering being carried out by the centering bolts 9.
  • the gear carrier 20 now moves with the gear block 16 and the coupling frame 18 in the horizontal direction according to the double arrow Pf 1 in direction b. Due to the different diameters of the forming rollers 3 and 4 from the forming roller pair to the forming roller pair, the position of the upper working shaft 5 and thus the upper coupling half 14 also changes with each exchanged forming roller pair. So that the pins 28 of the coupling half 19 can be inserted into the holes 27 of the coupling half 14, the height of these coupling halves 14 and 19 must be adapted to one another. This is done by interrupting the infeed of the gear carrier 20 in direction b at b1, that is to say after part of the distance, and then lifting the upper bearing housing 18a of the coupling frame 18 upwards by means of the cylinder 26.
  • This stroke movement is automatically and automatically limited by the adjusting arm 25. If this arm 25 is in contact with the coupling half 14 serving as a counterstop, the position is reached in which the pins 28 of the coupling half 19 can be moved into the holes 27 in the coupling half 14, which is caused by a further displacement of the drive group in the direction of the double arrow Pf 1 from b1 to b.
  • the respective coupling half 19 can dodge axially in the axial direction against the force of the spring 29 if the pins 28 do not exactly meet the perforations 27. With a slight rotational movement of the coupling halves 19, the pins can be brought into line with the perforations and then inserted by the springs. This completes the tool change process fully automatically and very quickly and machine 1 is ready for production again.
  • a profiling machine 1 with one or more pairs of forming rollers 2 arranged one behind the other in the direction of feed of a workpiece, which are parted in tool stands 6, has between a gear block 16 and the ends of the working shafts 5 of the shaping rollers 3 and 4 facing them 17 and couplings 15 for Loosen the drive connection of the forming rollers 3 and 4 if they are to be replaced.
  • a coupling frame 18 is provided between the respective tool frame 6 and the associated gear block 16, on the side facing the gear block 16 the drive shafts 17 and on the side facing the tool frame 6 the releasable couplings 15 for the working shafts 5 are arranged.
  • the gear block 16 can, together with the coupling frame 18, transversely to the feed direction of the workpiece and transversely to the working direction of the forming rollers 3 and 4 for releasing the couplings 15 be moved away from the tool frame 6.
  • the mounting of at least the upper propeller shaft 17 can be mechanically adjusted in height on the coupling frame 18 and a sensor, sensor or the like is either on the coupling frame 18 or on the tool frame 6. Switching element for automatic and automatic adjustment to the respective height of the counter clutch 14 is provided.
  • the displacement drive for the gear block 16 with the coupling frame 18 is controlled in such a way that the displacement movement or its last part for engaging takes place only after the height adjustment of the coupling halves on the coupling frame.
  • the arm 25 which is displaceable from below upwards against the counter-stop
  • the coupling half 14 could also be reversely adjustable downward from an upper starting position of the bearing housing 18a.
  • the arm 25 is attached to the height-adjustable bearing housing 18a and the counter-stop is arranged in its adjustment path. If it is on the roll stand, the coupling half 19 can come to rest against the arm 25 when the adjustment takes place from a lower or upper starting position if the height positions of the coupling halves match.
  • FIG. 3 shows a somewhat modified embodiment of a profiling machine 1, in which all the essential parts and their functions correspond and which are therefore marked accordingly in the drawing, but are no longer described in detail.
  • the gear block 16 and the coupling frame 18 are each fastened on their own carrier or bearing 20a and 20b and only the coupling frame 18 or the carrier 20b carrying the coupling frame 18 can be adjusted by means of a drive, in the exemplary embodiment of a motor-driven spindle 30 in guides 31 transversely to the direction of advance of the workpiece and in the axial direction of extension of the working shafts 5. Since the length of the cardan shafts 17 is continuously and automatically adjustable by pushing or pulling them apart and can also be adapted to different heights of the couplings, this adjustment movement of the coupling frame 18 is also possible without any problems regardless of the gear block 16.
