Definitions

  • the invention relates to a method for producing a profile having a different thickness cross section of flat metal strip by roll forming.
  • a roller pair on at least one side of the metal strip generates at least one first recess, which is widened by the following roller pairs with increasing groove width to a region with reduced material thickness.
  • Such a method is for example from the DE 36 22 926 A1 known.
  • a flat sheet is passed through a rolling mill having a very large diameter central work roll and a plurality of second work rolls of substantially smaller diameter disposed on the outer circumference of the first work roll.
  • the second work rolls are arranged one behind the other and each have one or more projections on its outer periphery, wherein the width of these projections of successively arranged second work rolls increases.
  • the flat sheet is deformed so that it comes to a special cross-sectional shape with one or more longitudinal grooves or grooves on one side.
  • wave formation can occur in the sheet.
  • first central work roll having a large diameter With the plurality of second work rolls having a substantially smaller diameter, which are arranged on the first central work roll, this wave formation is to be reduced.
  • holding plates can be provided, which are arranged between the second work rolls and press the sheet in this area on the outer circumference of the central work roll, so that the sheet does not bulge in these areas to the outside.
  • the work areas of the upper pressure rollers press the metal strip against the frusto-conical work areas of the lower roller and thus exert a shearing force on the metal strip.
  • the arranged in these areas material of the metal strip is thereby displaced laterally, so that areas of lesser thickness arise. Due to the lateral displacement of the material, a wave formation is avoided.
  • the EP 1 847 334 A1 shows a method for reducing the thickness of one-piece rolling.
  • the rolling stock is provided in a first step with at least two at a distance from each other parallel to the longitudinal extent extending bends.
  • the rolling stock is deformed in the width direction by means of rolls which penetrate the feedstock at different depths into the starting material.
  • the rolls are arranged opposite one another and each have at least one embossing region arranged obliquely to the axis of rotation of the rolls, which engages in the rolling stock in the region between the turns and reduces the rolling stock in thickness.
  • Object of the present invention is to provide a method in which the production of areas with reduced material thickness is facilitated and the formation of waves in the production of a profile of flat metal strip with in the transverse direction of the metal strip of different material thickness is further reduced or avoided. This object is achieved by a method having the features of claim 1.
  • the regions of the flat metal strip arranged adjacent to the at least one recess are moved out of a plane spanned by the central part of the metal strip, so that they are in contact with it Make an angle at the center of the metal band.
  • the bending of the respective areas can be done in both directions, ie, if the metal strip is moved horizontally in the process, the corresponding areas can be set up or down.
  • This change in the cross-section of the flat metal strip increases the rigidity of the metal strip, the metal strip with the bent-up areas then has a larger moment of resistance, which reduces or avoids wave formation during forming. Especially with wide metal bands is desired that these bent-up areas are not too far away from the at least one puncture. However, the portions of the metal strip that are bent open need not be disposed immediately adjacent to the at least one recess. The effect of facilitating the formation of a region of lesser material thickness by bending the respective regions and engaging the rollers to create or spread the puncture can be utilized in multiple roller pairs.
  • the metal strip acquires the desired higher rigidity right at the start of the forming process.
  • pairs of rollers for generating the respective groove in the bending region of the bent areas engage in the metal strip by the bending of the corresponding areas of the metal strip, a forming process is initiated, the material of the metal strip begins to flow in the bending area , whereby the material displacement is further facilitated by the engaging rollers in forming or widening the puncture.
  • the areas of the metal strip are bent in the direction of the side of the metal strip, in which the at least one puncture takes place.
  • the recess forming roller can be used as a stop for bending the corresponding areas of the metal strip, whereby the bending is facilitated.
  • a lighter formation of the puncture is possible, the risk of cracking in the region of the puncture is reduced.
  • the groove widening the groove of each roller pair first with the or the bent-up areas of the metal strip engages and presses against the corresponding counter-roller of the roller pair before the puncture is widened.
  • the first roller first engages the metal strip with only part of its peripheral surface, which requires only a smaller force.
  • the effect of simultaneously bending the corresponding areas of the metal strip and penetrating the first roll into the metal strip facilitates lateral material displacement even after the maximum pitch angle has been reached, when the bent areas of the flat metal strip come to rest before each other pair of rolls be bent back in the direction of a plane passing through the central part of the metal strip level.
  • the corresponding areas are easily pulled away from this plane, so that the desired Aufstellwinkel is reached again by the re-bending before the next pair of rollers re-bending the corresponding areas.
  • the maximum angle between the bent-up portions of the metal strip and the middle portion of the metal strip in the range of 10 ° to 80 °, preferably at 30 °, experiments have shown that this angle range particularly suitable is. In this area, the effect is exploited that simultaneous bending of the respective areas and penetration of the rollers into the material of the metal strip to produce regions of lesser material strength results in facilitating the lateral displacement of the material. At the same time, the profile in this angular range is not closed too far, so that the roller pairs of the roll forming can still attack well on the metal strip.
  • edges of the flat metal strip are bent.
  • the correspond bent areas around the edges This is particularly advantageous for narrower metal bands.
  • Another positive effect can be achieved if the side edge of the region of lesser material thickness arranged closer to the center part of the metal strip maintains a constant position. The material of the metal strip is thus pushed in the region of lesser material thickness only to the outside, so that in the central region of the metal strip no undesirable accumulations of material can occur, which may eventually produce waves or bending of the metal strip.
  • the method comprises further production steps such as stamping or embossing. These manufacturing steps can also be done before forming the flat metal strip to profile. As a result, all desired processing steps of the profile can be carried out in one system.
  • Fig. 1 shows a side view of a roll forming 1 for performing the manufacturing method according to the invention for a profile 8, which has a cross section with areas of different material thickness or thickness.
  • the roll forming 1 comprises a plurality of on roll stands (not shown) arranged roller pairs 2.1, 2.2; 3.1, 3.2; 4.1, 4.2; 5.1, 5.2; 6.1, 6.2. In Fig. 1 not all roller pairs of the roll forming 1 are shown. Between the roller pairs shown one or more pairs of rollers are omitted.
  • the roll forming 1 is supplied flat metal strip 7, which is preferably rolled up into a coil.
  • strip material for example steel, stainless steel high-strength steel, copper or aluminum and copper alloys or aluminum are used.
  • the flat metal strip 7 is formed into a profile 8.
  • steps are provided in the rollforming installation 1 in order to reduce the material thickness of the flat metal strip 7 in regions extending in the longitudinal direction of the metal strip 7 or of the profile 8, ie in the rolling direction.
  • the finished profile 8 therefore has a cross-section with different thickness. It is already known to produce such profiles. A problem with such methods is that the material displaced from the areas of lesser material thickness must not be displaced longitudinally, otherwise waviness or bending of the metal strip may occur.
  • a first pair of rollers 2.1, 2.2 is provided, which is formed so that the edges 9.1, 9.2 of the metal strip 7 are bent before and / or during the production of the first recess.
  • the edge areas are bent.
  • adjacent to the or the punctures arranged areas are bent, which can also be arranged centrally in the metal strip.
  • the following describes the method for metal strips in which the edges are bent. The following description applies analogously but also for metal strips in which the adjacently arranged to the or the punctures areas do not correspond to the edges, but are arranged more centrally in the metal strip.
  • FIG. 2 A section through the pair of rollers 2.1, 2.2 is in Fig. 2 shown. In this figure, only one half of the rollers 2.1, 2.2 is shown.
  • the lower roller 2.2 has two circumferential projections 10.1, 10.2, which engage in the metal strip 7 at the point at which the inner edge of the areas 12.1, 12.2 should trust with less material thickness, and the first recesses, ie areas with reduced material thickness 12.1, 12.2, generate.
  • the lower roller 2.2 has two projections 10.1, 10.2.
  • the projections 10.1, 10.2 are very narrow, so that pressed through the first pair of rollers 2.1, 2.2 only narrow grooves in the metal strip 7 become.
  • the roller diameter decreases, so that the end portions of the roller 2.2 are frusto-conical.
  • the arranged on the opposite side of the metal strip 7 roller 2.1 has an inner region with a constant diameter.
  • the interior is slightly longer than the distance of the projections 10.1, 10.2 on the lower roller 2.2.
  • the diameter of the upper roller 2.1 increases continuously, so that the roller 2.1 in the outer region is also frustoconical. Due to the inclined edge regions of the upper roller 2.1 and the lower roller 2.2, the edges 9.1, 9.2 of the flat metal strip 7 are bent downwards.
  • the projections 10.1, 10.2 arranged on the lower roller 2.2 serve as counterparts or bending edges, and thus facilitate the bending of the edges 9.1, 9.2 downwards. But it can also be provided réellebiegen the edges upwards.
  • both the upper roller 2.1 and the lower roller 2.2 are shown in one piece. But it can also be provided that these roles are composed of several individual pieces. Thus, for example, it may be provided that the middle region of the upper roller consists of a roller piece of constant diameter, to which join two further roller pieces whose diameter increases from the inside to the edge of the upper roller, so that these roller pieces are substantially frusto-conical. Similarly, the lower roller may be formed.
  • Fig. 3 shows a section through another pair of rollers 3.1, 3.2 along the line III-III Fig. 1 , Again, the lower roller 3.2 again circumferential projections 11.1, 11.2. However, the projections 11.1, 11.2 have a greater width than the projections 10.1, 10.2 on the lower roller 2.2 of the roller pair 2.1, 2.2 from Fig. 2 , The distance of the inner edge of the circumferential projections 11.1, 11.2 is identical to the distance between the inner edges of the circumferential projections 10.1, 10.2 on the roller 2.2. Between the pairs of rollers 2.1, 2.2 and 3.1, 3.2 further roller pairs are arranged in the roll forming 1, which are not shown. The width of the circumferential projections on the lower rollers increases on these pairs of rollers, so that the width of the areas with lower material thickness 12.1, 12.2 is increased in the roller pairs.
  • the lower roller comes first with the bent edges 9.1, 9.2 of the metal strip 7 into contact and pushes them against the upper roller, before the circumferential projections engage the lower roller in the metal strip 7 and widen the puncture. Again, the outer edge of the circumferential projections of the lower roller enters first into the metal strip 7. The required forming force is thereby reduced.
  • the inner edges of the circumferential projections have a constant distance on all roller pairs.
  • the distance between the inner edges of the areas with lower material thickness 12.1, 12.2 is constant.
  • the displaced from these areas material is thus pushed only to the outside, so that no material accumulation can occur in the central region 14 of the flat metal strip 7. Since the circumferential projections always rest over the entire width of the regions 12.1, 12.2 with less material thickness on the flat metal strip 7, a groove formation in these areas 12.1, 12.2 is avoided with less material thickness.
  • the end portions of the lower roller 3.2 and the upper roller 3.1 are again frusto-conical, the end portions of the upper roller 3.1 are formed so that their diameter increases to the ends of the upper roller 3.1.
  • the end portions of the lower roller 3.2 are formed opposite thereto, so that the diameter of the lower roller 3.2 on both sides, starting from the projections 11.1, 11.2 decreases continuously and at the ends of the roller 3.2 has the lowest value.
  • the opening angle of these frustoconical portions of the rollers 3.1 and 3.2 may be greater than the opening angle of the frustoconical portions of the rollers 2.1, 2.2 Fig.
  • the opening angle of the frusto-conical portions may increase from pair of rollers to pair of rollers until a maximum value of the opening angle is reached.
  • the edge regions 9.1, 9.2 of the flat metal strip 7 are thus bent in each pair of rollers a piece further down until a maximum installation angle is reached.
  • the maximum installation angle corresponds to the maximum opening angle of the frustoconical areas of the rollers.
  • Fig. 1 the maximum value of the opening angle and therefore also the maximum value of the setting angle is already reached with the roller pair 3.1, 3.2.
  • Fig. 4 shows a section through the third pair of rollers 4.1, 4.2 Fig. 1 , Also in Fig. 4 only one half of the upper roller 4.1 and the lower roller 4.2 is shown in each case.
  • the lower roller 4.2 in turn has peripheral projections 13.1, 13.2, which again have a greater width than the circumferential projections 11.1, 11.2 in the lower roller 3.2 Fig. 3 , The width of the areas of lesser material thickness 12.1, 12.2 extending in the longitudinal direction of the flat metal strip 7, so is further increased.
  • the lower roller 4.1 and the upper roller 4.2 again have frustoconical end portions, wherein the diameter of the upper roller 4.1 increases to the ends of the upper roller 4.1 and the lower roller 4.2 is formed opposite thereto, so that their outer diameter, starting from the circumferential projections 13.1, 13.2 decreases towards the ends.
  • the opening angle of these truncated cones has reached its maximum value at which a good engagement of the lower roller 4.2 in the flat metal strip 7 is still possible. This maximum value is in a range of 10 ° to 80 ° and is preferably 30 °.
  • the edges 9.1, 9.2 of the flat metal strip 7 are pulled inwards.
  • edges 9.1, 9.2 of the flat metal strip are again bent outwards a bit, so that in each pair of rollers simultaneous bending of the edges and engagement of the circumferential projections takes place in the flat metal strip 7.
