Definitions

  • the invention relates to a Profiliergerüst for a Rollumformstrom according to the preamble of claim 1 (see, eg US-B-6-282 932 ).
  • the Profiliergerüst comprises a frame with a first forming roller and a second forming roller, between which a material strip to be formed is passed to reshape it into a profile, or a corresponding profile is passed to further reshape it.
  • the form rollers can be driven or free-running.
  • At least one of the two forming rollers is seated on a shaft, in particular a drive shaft, which in turn is mounted in an eccentric bush so that a rotation of the eccentric bushing causes an axially parallel, lateral displacement of the shaft relative to the frame, by the distance of the two forming rollers to each other adapt different material strip thicknesses.
  • Roll forming plants in which such Profiliergerüste be used, consisting essentially of a variety of such Profiliergerüsten in line, passed through which the reshaped into a profile material band and successively transformed into the desired final profile.
  • the material strip in each case passes through at least two cooperating forming rollers, which transmit the forces for forming the material strip on this. The distance between these at least two cooperating shaping rollers must be adapted to the thickness of the material band.
  • the Profiliergerüste In order to be able to profile material strips with different thicknesses in one and the same Rollumformstrom, the Profiliergerüste must be provided with such adjustable mold rollers that the distance between the cooperating mold rollers changeable and the changed material strip thickness is customizable. However, since high forces must act to deform the material strip, which act in particular in the direction of the connecting path between the forming roller axes of the cooperating shaping rollers, it is difficult to realize such an adjustment. Because the adjustment mechanism must withstand the high forming forces.
  • the rotational movement on the eccentric bush which is necessary for a lateral, axially parallel displacement of the forming roller, naturally leads to a rotation of the forming roller about the shaft axis or about the axis of the eccentric bushing.
  • this rotation is not a problem, because the form roller is then designed to be rotationally symmetrical about this axis.
  • the known eccentric adjustment of the forming rollers becomes problematic when the profiling stand is a helical roller unit, that is to say that at least one of the two forming rollers has an axis of rotation which is angled relative to the axis of the associated shaft mounted in the eccentric bushing. Because if then the eccentric bushing twisted is moved, the axis of the angled arranged form roller along a conical surface moves out of the working position.
  • the present invention is therefore the object of a profiling with eccentric adjustment of the distance of the forming rollers of the type described above to modify so that the eccentric adjustment of the distance of the forming rollers is also used when the eccentric to be adjusted form roller is angled relative to its shaft That is, it is the Profiliergerüst so a Schrägrollentician.
  • the Profiliergerüst known from the prior art with eccentric adjustment of the mold roller spacing is therefore modified according to the present invention in that the eccentric bush associated with the form roller is mounted on a support sleeve which is rotatably mounted in the eccentric bush and laterally displaceable mounted on the frame, so because of the only laterally displaceable attachment to the stationary frame can not rotate with the eccentric bushing. Accordingly, the adjustable form roller or its axis does not twist during rotation of the eccentric bush.
  • the support sleeve is laterally slidably mounted on the frame via at least two rotatably seated in the frame and in the support sleeve eccentric, said eccentric preferably have the same eccentric dimension as the eccentric bushing.
  • the eccentric bushing is twisted, the carrier sleeve will try to rotate as well as forcefully move laterally parallel to the axis.
  • the support sleeve is prevented from rotating.
  • this desired articulated behavior of the carrier sleeve can also be achieved by means of a joint arrangement or a correspondingly designed link guide of non-eccentric retaining bolts. It is important within the scope of the invention in each case only that the support sleeve is prevented from rotating relative to the frame, while a lateral displacement corresponding to the lateral displacement of the axis of the rotated eccentric bushing is possible. Nevertheless, the solution over eccentric bolts is particularly preferred.
  • the invention is preferably used in Profiliergerüsten which have at least one forming roller whose axis of rotation is angled relative to the adjustable over the eccentric bushing axis of the associated shaft, so there is a Schrägrollenhow; in particular if a housing fastened to the carrier sleeve is provided, on which the forming roller assigned to the eccentric bushing is mounted, and which includes a deflection for transmitting the torque to the shaft on the forming roller, for example a universal joint or bevel gears.
  • eccentric bushing and / or the carrier sleeve of the profiling stand according to the invention are formed axially adjustable relative to the frame.
  • axially parallel forming rollers genügtes usually not only to increase the distance between the two axes of the cooperating form rollers to perform a thicker material band or a thicker profile, but it must also be an axial offset two co-operating form roles are increased or reduced.
  • helical roller units this is immediately obvious;
  • an axial offset is necessary if the metal strip passed through has or should have a profile whose cross-section not only extends horizontally but also has a vertical component.
  • the axial adjustment of the eccentric bush and / or the carrier sleeve is independent of the rotation of the eccentric bushing. Because then not only a synchronous adjustment of the axial distance and the axial offset can be done, but also an asynchronous adjustment.
  • this can have a concentric to its outer surface thread on which a gear wheel with internal thread runs, which in turn is mounted axially non-displaceable relative to the frame.
  • an actuator can be provided with a further gear, which meshes with the aforementioned gear with internal thread.
  • To rotate the eccentric bush may be mounted on this a pivot lever whose leverage reduces the counterforce of the deformation, which aims to cause a rotation of the eccentric bushing again.
  • a pivot lever whose leverage reduces the counterforce of the deformation, which aims to cause a rotation of the eccentric bushing again.
  • At least one side roll in particular a running side roll, can be associated with the first and second forming rolls, especially if the profiling frame according to the invention is a skew roll unit.
  • the eccentric bushing is preferably slidably mounted while the eccentric bolts are roller-mounted. This reduces the resistance of the eccentric bolt against a desired lateral displacement of the shaft axis, while the eccentric bushing is not stored too smoothly to achieve a self-locking the Vercardne Trent due to the opposing force of the forming forces on the forming rollers. This self-locking can be so pronounced that no external holding forces must act on the eccentric bushing.
  • FIG. 1 shows a profiling scaffold 10 constructed according to the invention in a lateral sectional view. This comprises two cooperating, driven shaping rollers 11 and 12, between which an already pre-profiled material band 31 (FIG. FIG. 10 ) is passed, and with which further cooperates a free-running side roller 14.
  • the Profiliergerüst 10 includes next to another form roller pair 13 and 12 and a cooperating with these two free-running side roller 15th
  • the profiling stand 10 further comprises a frame 16 in which drive shafts 32, 33 and 34 for the forming rollers 11, 12 and 13 are mounted.
  • the present profiling stand 10 is designed as a skew roller unit, ie the forming rollers 11 and 13 have rotation axes 35 and 36, which are angled relative to the axes of the associated drive shafts 32 and 34. Accordingly, in each case a housing 17, 18 is provided, on which the forming rollers 11, 13 are mounted are, and which the deflection for transmitting the torque from the drive shafts 32, 34 on the forming rollers 11, 13, in this case a (not shown) bevel gear, include.
  • the drive shaft 32 is mounted in an eccentric bushing 20, which can be rotated via a pivot lever 25.
  • a rotation of the eccentric bush 20 causes a lateral, axially parallel displacement of the drive shaft 32 and the housing 17, so that the distance between the forming rollers 11 and 12 changes in the y-direction.
  • a carrier sleeve 19 is inserted into the eccentric bushing 20, on which the housing 17 is attached.
  • the support sleeve 19 makes the lateral movement of the drive shaft 32 during rotation of the eccentric bush 20 forcibly with, but it is rotatably mounted in the eccentric bushing 20, and it is prevented by a corresponding attachment to the frame 16 from rotating with the eccentric bushing 20. Accordingly, the rotation axis 35 of the forming roller 11 remains unchanged upon rotation of the eccentric bushing 20.
  • FIGS. 5, 6 and 7 in each case a partial view along the section AA FIG. 1 are, while the Figurren 5a, 6a and 7a partial outbreaks along the section BB from FIG. 1 represent.
  • the drive shaft 32 is rotatably mounted in the support sleeve 19 and this turn rotatably in the eccentric bushing 20, and this in turn rotatable in the frame 16.
  • the support sleeve 19 has a in this section all over seeing Head plate, which is provided with four holes. In each of the holes sits an eccentric pin 21, 22, 23 and 24, whose eccentric e is the same eccentric, as that of the eccentric sleeve 20th
  • the eccentric pins 21, 22, 23 and 24 are each freely rotatably mounted both in the top plate of the support sleeve 19 and in corresponding holes in the frame 16, by means of rolling bearings 37 in this particularly easy to rotate.
  • FIG. 10 shows an already profiled material strip 31, which is further formed between the forming rollers 11 and 12 and the side roller 14 - that it is not sufficient to adapt to different thicknesses of the material strip 31, to adjust the forming roller 11 in the y-direction.
  • a synchronous adjustment in the x-direction must be added since the shaping roller 11 acts approximately in the bisecting line of the form roller 12 and side roller 14 which are perpendicular to one another. For other angles, an asynchronous adjustment in the x direction must be carried out accordingly.
  • the rotation of the eccentric bushing 20 via the pivot lever 25 can be effected by means of an actuator (not shown here); so that both the adjustment of the forming roller 11 in the x direction and the adjustment of the forming roller 11 in the y direction by means of NC axis controls can be synchronous or asynchronous.
  • FIG. 9 shows.
  • a single actuator thus acts on a whole series (here on two) Profiliergerüste 10 and 10 '.
