Definitions

  • the invention relates to a rolling device for the production of stainless steel plates for drying wet masonry, which are driven into the masonry and are corrugated to increase their rigidity, the waves running with their longitudinal axis in the driving direction, with two deformation rollers have a gear-shaped profile in cross-section which forms deformation ribs which run in the axial direction and which mesh with one another in the manner of gearwheels, the axial distance between the two deformation rollers being greater than the sum of the radii of the pitch circles of the toothed rollers.
  • the invention also relates to a plate produced with this rolling device.
  • the corrugation of the insulating plates increases their rigidity. In the known wave-shaped insulating plates, it can still happen that the plates unintentionally bulge and deform when driven into the masonry, whereupon they can jam in the mortar joint between the guides or against each other.
  • the boards can be made of harder and thicker material according to general knowledge. However, this considerably complicates the wave-shaped profiling and also the breaking of the plates.
  • the simplest way to produce such corrugated plates is by rolling or pressing, with them being deformed over their entire width simultaneously between profiled pressing tools or being passed through profile rollers in the longitudinal direction of the shafts.
  • this deformation is only possible when using plates made of relatively soft, easily deformable steel, because stretching of the material occurs here, which is due to the profiling process and is therefore unavoidable.
  • hard material that has a ferritic structure and is not stretchable cracks occur that make the boards unusable or at least cause disadvantageous deformations when driving the boards into the masonry.
  • DE-OS 25 05 199 describes a method for producing ventilation ducts, pipe claddings and the like.
  • the so-called cross-profiling is used to produce corrugated channel walls.
  • Deformation rollers are used, which are arranged at a certain distance from one another and interlock with deformation ribs running in the axial direction.
  • a flat sheet metal sheet is passed through these toothed rollers, which is deformed into a corrugated profile with a trapezoidal profile cross section and then cut into the individual components with the aid of a cross cutting device.
  • This profiling process is basically also possible with hard material because the sheet metal plates are only bent when they are deformed, but not stretched over the entire cross section. To achieve this, however, certain design features of the rolling device are required, and particular care must also be taken to ensure that the finished corrugated plates have a profile cross section which makes them suitable for their particular purpose.
  • the invention has for its object to provide an improved rolling device with which it is possible to produce corrugated plates for draining damp masonry made of stainless steel so that they have an advantageous profile for driving into the masonry despite the use of hard material and do not deform during driving, in particular also have no cracks due to the profiling which could endanger the moisture insulation.
  • the rolling device according to the invention is characterized in that the interlocking deformation ribs are formed on their flanks as an involute profile, to which the profile of the tip circle and the base circle connects, that the pressure angle of the deformation ribs in the area of the pitch circle is at least 30 ° and that The tooth height of the deformation ribs is at least 15% of the radius of the pitch circle.
  • This relatively simple rolling device enables the production of the described plates with the advantageous cross-sectional profile, which can consist of hard steel with a ferritic structure, without cracks or other damage occurring during rolling.
  • the formation of the deformation rollers according to the invention ensures that only one deformation rib of one deformation roller is in engagement with one deformation rib of the other deformation roller, thereby avoiding stretching of the material over the entire deformation cross section of the deformed plates and the resulting cracks.
  • the possible diameter of the deformation rollers is limited.
  • the forming rollers which have to be long enough so that long plates, e.g. with a length of one meter and more, can be profiled, therefore have a limited bending stiffness.
  • the deformation rollers held at their ends in bearings are provided with support rollers which act on the deformation rollers at diametrically opposite locations on the deformation rollers in the region between the bearings. It is then also possible to process relatively thick sheets without difficulty.
  • the support rollers expediently have a tooth profile with the same tip circles and root circles as the deformation rollers and are in engagement with them. It is a further advantage if the distance between the support rollers and the associated deformation rollers is adjustable. The appropriate contact pressure can then always be set depending on the thickness and rigidity of the processed sheet.
  • the distance between the deformation rollers, including any support rollers, can also be adjustable, for example by means of a wedge or vertical spindle bearing adjustment. This measure also serves to adapt the rolling device to the thickness of the sheets used and also to change the height of the corrugated profiles.
  • the support rollers are expediently provided in pairs, with a plurality of support roller pairs being arranged alongside one another along the deformation rollers and being adjustable separately from one another. This further increases and improves the possibility of adapting the rolling device to the respective operating conditions.
  • the deformation rollers for synchronizing their rotational movement are provided with gears which are rotatably mounted on them and which mesh with one another.
  • the deformation rollers themselves and their deformation ribs are thereby relieved of influences and forces which are necessary for synchronization, thereby precluding an adverse change in the wave profile of the plates due to such forces. It is advisable to provide the deformation rollers with their own drive motors with the interposition of elastic couplings.
  • a further advantageous embodiment of the rolling device according to the invention is that straightening rollers through which the plates are guided are arranged on the inlet side and / or on the outlet side of the forming rollers. These straightening rollers not only effect the correct feeding of the plates to be profiled into the rolling device, but in particular they ensure that the finished corrugated plates just leave the rolling device. This eliminates the need to straighten the plates afterwards.
  • the straightening rollers with rubber or plastic coated cylindrical rollers are advantageous. They can be arranged so as to be adjustable transversely to the direction in which the plates pass through the shaping rollers, as a result of which their position and their mutual spacing can be adapted to the respective properties of the plates and the operating conditions.
  • the straightening rolls are expediently empirical adjusted each time until the corrugated plates produced have a sufficiently precise flat shape.
  • a preferred embodiment of the rolling device according to the invention consists in that the deformation rollers are each rotatably mounted in a box-shaped housing, the housings are arranged one above the other in a frame so as to be adjustable relative to one another and have guide shafts provided one behind the other in the longitudinal direction of the deformation rollers, into which the support rollers are slidably inserted and in which they are supported by a set screw. It is a simple and robust rolling device, which nevertheless enables precise adjustment.
  • the straightening rollers are arranged on the box-shaped housings and are preferably supported with the aid of adjusting spindles, so that they can also be adjusted in a simple manner.
  • a plate made of stainless steel can also be produced, in which, according to the invention, the wave profiles adjoining one another via turning points are circular. At the turning points, two circular sections with opposite curvatures adjoin each other, so that there are practically no flat patches in the area of the turning points.
  • a plate profiled in this way does not have the greatest possible stiffness and is in particular less stiff than a comparable plate with a rectangular or trapezoidal wave profile.
  • FIG. 1 shows a perspective view of a plate produced with the rolling device according to the invention
  • FIG. 2 shows the enlarged wave profile
  • FIG. 3 shows a detail of the rolling device for producing the corrugated plate
  • FIG. 4 shows the entire rolling device in a schematic representation
  • 5 shows a side view of the rolling device, partly in an axial central section
  • FIG. 6 shows a cross section through the rolling device along the line VI-VI in FIG. 5.
  • the plate 1 shown in Fig. 1 is made of stainless steel and is corrugated to increase its rigidity.
  • the waves denoted by 2 in FIG. 1 run parallel to one another.
  • the entire (cross-sectional profile 3 of a plate 1 is composed of a plurality of wave profiles 4, which adjoin one another to form wave crests and wave troughs.
  • the cross-sectional profile 3 is curved in its entire course, the adjacent wave profiles 4 only via turning points 2, the wave profiles 4 are circular in shape in the exemplary embodiment according to Fig. 2.
  • the straight line 6 shown in dash-dotted lines passes through the apexes of a wave crest and the adjacent wave trough as well as through the intermediate turning point 5, the curved course of the cross-sectional profile 3. It is also possible within the scope of the invention to deviate from the circular wave profile, which is also curved differently can be. It is only essential that flat surfaces are avoided in the course of the cross-sectional profile, because flat areas would favor a local deformation of the plate.
  • the corrugated plates 1 must be made of hard, stainless steel so that they withstand the mechanical stresses acting on them and do not weather in the masonry itself.
  • the materials that meet these requirements can be difficult to deform, especially because they are not stretchable.
  • sheet metal panels made of such material are stretched, cracks and sores occur, which, when the panels are driven into the masonry, impair the bending stiffness and the tightness is no longer guaranteed after driving in.
  • the rolling device shown schematically in Fig. 3 enables the production of corrugated sheet metal plates made of hard material without this being stretched over the entire deformation cross section.
  • the rolling device according to FIG. 3 consists of two deformation rollers 7 and 8, which in cross section have a gear-shaped profile with deformation ribs 9 and 10.
  • the two deformation rollers 7, 8 are rotatably arranged one above the other with parallel axes, their deformation ribs 9, 10 meshing like a gear.
  • the center distance of the two deformation rollers 7, 8 is greater than the sum of the radii of the rolling circles 11 and 12 of the toothing of the rollers 7, 8, shown in dash-dot lines in FIG. 3. This creates a space between the interlocking deformation ribs 9, 10, between the successive ones Plates 1 are inserted to be provided with shafts 2.
  • the interlocking deformation ribs 9, 10 are formed on their flanks 13 and 14 with an involute profile, to which the profile of the tip circle 15 and the root circle 16 adjoins.
  • the deformation rollers 7, 8 are designed and arranged such that only one deformation rib 9 of the one deformation roller 7 engages with the deformation ribs 10 of the other deformation roller 8 stands.
  • the deformation rollers 7, 8 are designed with a relatively small diameter compared to the tooth height 17 of the two deformation rollers 7, 8.
  • the tooth height 17 is at least 15% of the radius of the pitch circle 11, 12 of the associated deformation roller 7.8.
  • the plate 1 is inserted in the still flat state in FIG. 3 from the left between the two deformation rollers 7, 8, which are driven at the same speed and in opposite directions.
  • the plate 1 is deformed and provided with the shafts 2 between the deformation ribs 9, 10 of the deformation rollers 7, 8.
  • the plate 1 can slide in the direction of its plane, so that only its width is reduced.
  • Fig. 4 shows schematically the entire Walzvorrichtnng with the deformation rollers 7, 8, the deformation ribs 9, 10 and with the sheet metal plate 1, which is provided with the shafts 2 when passing through the device in the direction of the arrows.
  • the shaping rollers 7, 8 must, however, have a relatively small diameter in order to be able to deform the plates 1 without stretching.
  • the relatively thin deformation rollers 7, 8 can therefore bend, in particular with a greater length, which results in irregular wave heights over their length and the plates are given a convex shape.
  • FIG. 1 shows schematically the entire Walzvorrichtnng with the deformation rollers 7, 8, the deformation ribs 9, 10 and with the sheet metal plate 1, which is provided with the shafts 2 when passing through the device in the direction of the arrows.
  • the two deformation rollers 7, 8 with support rollers 19 are therefore and 20, each of which act on the deformation point at diametrically opposite positions on the deformation rollers 7, 8 on the latter.
  • the support rollers 19, 20 have the same gear profile as the deformation rollers 7, 8 and are in engagement with them, the toothings rolling directly onto one another.
  • the distance between the support rollers is 19, 20 adjustable to the associated deformation rollers 7,8.
  • the distance between the two deformation rollers 7 and 8 itself is expediently designed to be adjustable so that it can be adapted to the thickness of the plates 1 to be deformed and the height of the shafts 2 produced can be selected.
  • the bearings of the deformation rollers 7, 8 can be used for this purpose be provided with wedge or spindle bearing adjustments not shown in the drawing.
  • the deformation rollers 7 and 8 are each supported in a box-shaped housing 21 and 22, the two housings 21, 22 being arranged one above the other in a frame 23.
  • the housings 21 and 22 have guide shafts 24 which are provided one behind the other above or below the deformation rollers 7, 8 in the longitudinal direction thereof and are intended for receiving the support rollers 19, 20.
  • a support roller 19 is inserted in the middle guide shaft 24 above the deformation roller 7 and can be displaced with the aid of an adjusting screw 25 against the associated deformation roller 7.
  • Such a deformation roller 19 together with the adjusting screw 25 could be inserted in all six guide shafts 24 shown in FIG. 5.
  • the deformation rollers 7 and 8 are provided for synchronizing their rotational movement with gears 26 and 27 attached to them, which are in engagement with one another, as can be seen from FIG. 5.
  • the deformation rollers 7, 8 are also driven in this exemplary embodiment by means of their own drive motors 28, 29.
  • the on the frame 23 are anchored.
  • Elastic couplings 30 and 31 are switched on in the drive connection.
  • straightening rollers 32 are arranged on the inlet side of the deformation rollers 7,8 shown there on the left and straightening rollers 33 are arranged on the outlet side.
  • the straightening rollers 32, 33 advantageously consist of cylindrical rollers coated with rubber or plastic and are adjustable transversely to the direction of travel of the plates, so that their distance can be matched to the thickness of the plates.
  • the straightening rollers 33 are, as can be seen from FIG. 6, mounted on pivoting levers 34 and supported by means of adjusting spindles 35, so that they can be easily adjusted.
  • the rolling device shown and described is relatively simple in construction and nevertheless enables the advantageous production of corrugated plates made of hard stainless steel without the plate material being stretched during the deformation.
