Definitions

  • the invention relates to a profiling machine for longitudinally forming a metal strip or output profile into a profile or tube by means of a plurality of Rollumformwerkmaschineen according to the preamble of claim 1, and a method for longitudinal deformation of a metal strip or output profile in a profile or tube by means of such a profiling machine.
  • At least part of the roll forming tools of such a profiling machine is combined to form a plurality of tool groups arranged one behind the other in the working direction, each of which is held in a frame and forms a forming station with it. At least a part of the rolling forming tools arranged in a forming station is seated on upper and lower working shafts mounted in the framework, which are provided with coupling elements leading out laterally out of the framework.
  • clutch stand are arranged, on the one hand have coupling counterparts to the coupling elements of the working shafts and on the other hand connections for a drive system of the profiling to transmit torque from the drive system to the working shafts.
  • the coupling elements of the working shafts are usually made of coupling pins or sleeves, while the coupling stand is equipped with sleeves or pins which engage positively in the coupling pins or sleeves of the working shafts.
  • the coupling stand In order to disengage the working shafts of the forming stations from the drive system or to be able to couple to this, the coupling stand by means of displacement device to the scaffolds or away from them, so that the coupling elements of the working shafts and the coupling counterparts on the clutch stand either engage or be taken out of their engagement. In the case of coupling pin and sleeves this axial displacement is necessary.
  • the torque transmission is usually carried out by means of variable length propeller shafts.
  • Profiling machines are able to produce virtually endless profiles or tubes of various cross-sectional shapes from a metal strip or an output profile.
  • a multiplicity of roll forming tools are used for this purpose, which are grouped together in typically 20 to 30 forming stations arranged in line one behind the other. If a different profile shape is to be produced on one and the same profiling machine, a multiplicity of roll forming tools must accordingly be exchanged.
  • a coupling stand is provided in a profiling machine of the type described above between the forming stations and the drive system, which can engage and disengage the drive shafts, so that the Rollumformwerkmaschinegnee together with their drive shafts as Can be exchanged unit, without having to move the frame relative to the machine base or against a scaffold carrier plate.
  • An exchange of Rollumformwerkmaschinemaschine without subsequent lengthy adjustments, especially in the working axes axis-parallel direction is possible by the previous uncoupling of the drive system. This saves time when converting a Profiliermaschine to another profile shape and thus reduces adverse production stoppages.
  • a profiling machine of the present type is in the EP 0 365 976 B1 described.
  • laterally movable coupling stands be common move away from the frames of the forming stations to release the working waves. After replacing them the coupling stand moved up again almost to its coupled starting position to the scaffolds and determines the possibly changed installation height of the drive shafts. Then the coupling counterparts are moved vertically on the coupling uprights to adjust their height to the height of the respective working shaft.
  • the clutch stands are further moved together to the stands to engage the coupling elements and the coupling counterparts, whereby the Ankuppelvorgang is terminated.
  • a gear block of the drive system is moved with the coupling stands, or the changing distance between the coupling stands and the drive system is compensated by variable length drive shafts.
  • the present invention seeks to propose a profiling machine of the type mentioned above and a method using this profiling, with which the times of adverse production stoppages during conversion of a profiling on another profile shape can be further reduced.
  • the coupling stands are accordingly designed as manipulators and are used in particular in the context of the method according to the invention for the axial and / or vertical adjustment of the roll forming tools.
  • the trained as manipulators clutch stand and side rollers axially and / or vertically adjust.
  • the coupling stand can also make a lateral adjustment of the complete scaffolding or parts of the scaffolding.
  • the coupling stand of a profiling machine are preferably with first adjustment drives for axially parallel displacement or unilateral vertical adjustment (skew) of the upper and / or lower working waves provided.
  • the clutch stands comprise second adjusting drives for the axial adjustment of the roll forming tools seated on the upper and / or lower working shafts.
  • the coupling stands are provided with third adjusting drives for adjusting side rollers mounted in or on or next to the stands of the forming stations.
  • the clutch stand fourth Verstellantriebe for laterally adjusting the frameworks, ie at least one component of this lateral adjustment is oriented transversely or perpendicular to the direction of movement of the metal strip or initial profile to be formed.
  • These fourth adjusting drives are preferably at the same time also the displacement devices for moving the clutch stand to the stands and away from them.
  • the inventive design of the coupling stand as manipulators changes their property as a passive element in the prior art in an active element of the profiling, with the aid of a retooling or retraction of a profiling can be simplified and accelerated. Even while the profiling machine is in operation, the coupling stand according to the invention can assume manipulator functions, for example for readjustment work without interrupting production.
  • a forming station using the invention can now be uncoupled from the drive system with imported metal strip or output profile.
  • This is achieved in a preferred procedure in the context of the present invention, characterized in that the clutch stand a disconnected from the drive system forming station initially adjusted the upper working shaft vertically upwards and / or adjusted the lower working shaft vertically down to release tension and the coupling elements or Coupling counterparts to get as torque-free. Thereafter, then the clutch stand can be moved away from the frame to perform the Abkuppelvorgang.
  • the further new procedure is particularly advantageous, which enables the present invention:
  • the formation of the coupling stand as manipulators not only individual forming stations can be disconnected from the drive system, but also einzeine working waves, while the rest of the forming station remains coupled.
  • the corresponding coupling stand in fully uncoupled state move the coupling counterpart of the disengaged individual working shaft from the axial alignment with this working shaft, for example, in an upper or lower extreme position.
  • the clutch stand can be moved back to the frame to perform the Ankuppelvorgang.
  • the individually uncoupled working shaft naturally does not enter into engagement with the coupling counterpart moved up or down and thus remains without drive.
  • the Antriebslosstellen a single working shaft or a complete Umformstation with metal tape inserted can be particularly advantageous when retracting a profiling or optimization attempts during production. Because, as mentioned, all drive shafts of all forming stations must be coupled to the drive system when entering the metal strip in the profiling as possible to ensure the necessary transport of the metal strip.
  • the coupling stands can be moved individually toward or away from their respective stands, the new, comfortable possibility of successively transforming the forming stations results in accordance with the set-up progress a to be set up or to be converted profiling to couple to the drive system. As a result, the trial phase can be started prematurely and the set-up time can be reduced accordingly.
  • the coupling stand of a coupling station to be coupled to the drive system oscillating up and down at least one of the coupling counterparts, while it is moved to the frame to perform the Ankuppelvorgang.
  • the coupling can be done without a complex height adjustment of the coupling counterparts to the coupling elements of the drive shafts.
  • the small oscillating up and down movement of the coupling counterparts in the coupling stand ensures when coupling that they also engage with the respective coupling elements of the drive shafts, if the height adjustment previously only roughly took place. Even when uncoupling such a slight oscillating movement of the coupling counterparts may be advantageous because this can be easier to solve the coupling elements and the coupling counterparts from each other.
  • a pneumatic drive has resilient properties and is thus inherently provided with a kind of integrated overload protection, both during the coupling movement and during the uncoupling movement. So far so when coupling a drive shaft whose coupling element is offset relative to the coupling counterpart on the coupling stand in the direction of rotation, so the positive engagement producing parts of these coupling elements are not aligned and therefore can not engage each other, the pneumatic drive and thus the clutch stand stops.
  • the coupling stand will be damaged by its drive and pulls it, if an engagement of the coupling elements and the coupling counterparts is not possible; Rather, the pneumatic drive then generates only a spring force on the clutch stand, which elastically against him biases the frame of the forming station so that it moves on as soon as the coupling elements and coupling counterparts come to rest and engage in alignment by actuating the drive system.
  • the pneumatic drive brings only a resilient bias on the clutch stand, so that it moves away from the scaffold only when the coupling elements and the coupling counterparts can be solved each other, for example, by briefly reversing the drive system or by a manually applied vibration ,
  • the present invention further provides new possibilities in that the trained as manipulators clutch stand can be used to adjust the frameworks at least part of the forming stations laterally, for example on laterally displaceable quick release plates or along guides in quick release plates or the machine frame. As far as the displacement of the clutch stand actuators are used, any lateral position of the scaffolding can be approached reproducible. A profiling machine equipped in this way is accordingly suitable without additional set-up effort for the production of special profiles and profiles which are variable in the width direction.
  • a first subset of the laterally adjustable stands of the profiling machine according to the invention for forming only one arranged in the direction of movement of the metal strip or output profile left area and a second subset of laterally adjustable stands for forming only one in the direction of movement of the metal strip on the right Area serves.
  • This first subset and / or this second subset are then laterally adjusted by the associated coupling stands, preferably in each case in common, whereby the width of the forming area can then be changed or varied during production.
  • the trained as manipulators clutch stand can optionally also be used to move only parts of the scaffolding, especially a scaffold half, laterally to be able to easily and reproducibly change the frameworks in itself.
  • the coupling stands are provided with measuring devices for detecting the positions of the upper and / or lower working shafts, the Rollumformwerkmaschinee, the side rollers and / or the scaffolding.
  • Such measuring devices facilitate fully automatic adjustment of the adjustable parameters of the roll forming tools of a profiling machine, which naturally reduces set-up times and even makes it superfluous when converting to a previously produced profile shape.
  • the measuring devices may be designed so that they do not determine the positions of Rollumformwerkmaschinee directly, but indirectly, in particular by determining the positions of individual adjusting elements.
  • a correction factor or a link can be stored on this, which contains the determined by means of a precision measurement relationship between the position of the adjusting elements and the actual position of Rollumformwerkmaschinee.
  • FIG. 1 is a schematic cross-section through an inventively configured profiling a forming station 1 with an upper working shaft 2 and a lower working shaft 3 for receiving (not shown here) Rollformwerkmaschineen shown, the two working shafts 2, 3 are mounted in a frame 4.
  • This framework 4 stands on a quick-release plate 5, which is fastened by means of fastening elements 6 releasably attached to a machine frame 7.
  • the working shafts 2, 3 in the frame 4 can be moved vertically.
  • the metal strip or profile to be formed is guided by the (not shown) Rollformwerkmaschinemaschinee and thereby formed.
  • a gear block 9 of a drive system is arranged on a gear carrier 10.
  • a clutch stand 11 is interposed between the gear block 9 and the Umformstation1 .
  • two coupling counterparts 12 which are formed as a coupling pin. These can engage positively in coupling elements 13 of the drive shafts 2, 3, which are designed here as coupling sleeves.
  • the coupling elements 13 of the working shafts 2, 3 lead laterally out of the frame 4 towards the gear block 9.
  • the coupling counterparts 12 also continue as a coupling pin 14 to allow engagement in drive shafts 15, which transmit torque from the gear block 9.
  • the propeller shafts 15 are telescopically variable in length, in order not to hinder movement of the coupling stand 11 to the Umformstation1 and away from it.
  • FIG. 2 shows, however, not only the clutch stand 11 has been moved to the gear unit 9 out to disengage the drive shafts 2, 3 from the gear unit 9, but at the same time the two coupling counterparts 12 in the clutch stand 11 were moved vertically downwards or upwards. This was effected by means of two further pneumatic cylinders which form a vertical drive 18. This not only allows a height adjustment of the coupling counterparts 12 to adjust them to about changed height settings of the drive shafts 2, 3, but it is also possible by moving one of the two coupling counterparts 12 in such a Extreme position, as in FIG. 2 is shown to keep uncoupled this coupling counterpart of the associated working shaft 2, 3, although the other working shaft is engaged. Such a procedure is in the FIGS. 3 and 4 shown, in FIG. 3 the lower working shaft 3 and in FIG. 4 the upper working shaft 2 are switched without drive.
  • the vertical drive 18 of the in the FIGS. 1 to 4 The illustrated embodiment is otherwise adapted to produce small oscillating up and down movements of the coupling counterparts 12, so that both the coupling and uncoupling of the coupling counterparts 12 from the coupling elements 13 of the drive shafts 2, 3 as described above is facilitated.
  • the coarse adjustment of the height of the two coupling counterparts 12 to the vertical position of the coupling elements 13 of the two drive shafts 2 and 3 is otherwise characterized in that prior to coupling the forming station 1 both coupling counterparts 12 by means of the vertical drive 18 in the in FIG. 2 shown extreme positions are driven.
  • a first movement of the coupling stand 11 to the forming station 1 towards this moves into an intermediate position not shown in the figures.
  • FIG. 5 shows a representation corresponding to the preceding figures of another embodiment of an inventively designed profiling machine; It is therefore again a schematic cross-section with a forming station 1, which has an upper working shaft 2 and a lower working shaft 3 for receiving roll forming tools (again not shown here) for forming a profile 26 indicated here by way of example contains.
  • the two working shafts 2, 3 are also stored here in a framework 4, wherein the upper working shaft 2 can be adjusted up and down. This is done by means of a height adjustment 8, which is connected via worm gear or the like with bearing sleeves 27 of the upper working shaft 2.
  • FIG. 5 illustrated embodiment of the embodiment of the preceding figures substantially, is the coupling stand 11, which is no longer moved here by means of a pneumatic drive to the frame 4 and away from it, but by means of a servo motor 29, the clutch stand 11 via a spindle 20 Sliders 21 can slide along a slide 17 in any desired position.
  • the coupling counterparts 12 of the coupling stand 11 of this embodiment are spring-loaded in a conventional manner 22 so that they can yield when the coupling stand 11 is moved up to the frame 4 and an offset between the coupling counterparts 12 and the coupling elements 13 of the working shafts 2, 3 in the direction of rotation, so that they can not intervene directly.
  • FIG. 5 illustrated coupling stand 11 carries an adjusting drive 23 which comes into engagement with the height adjustment 8 during coupling and by means of which the upper working shafts 2 can be adjusted exactly in their height position. This height adjustment is thus effected by the trained as a manipulator clutch stand 11.
