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 known for example from DE 36 22 926 A1.
- 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 reshaped so that it gets 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.
- Object of the present invention is to provide a method in which 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.
- adjacent to the at least one recess arranged regions of the flat metal strip are bent before and / or during engagement of a pair of rollers. Bending is understood here to mean that the areas of the flat metal strip arranged adjacent to the at least one recess are moved out of a plane spanned by the middle part of the metal strip, so that they form an angle with this plane of the middle part of the metal strip.
- 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.
- the rigidity of the metal strip is increased, the metal strip with the bent-up areas then has a larger moment of resistance, whereby the wave formation during reduction is reduced or avoided.
- these bent-up areas are not too far away from the at least one puncture.
- the portions of the metal strip that are bent open need not be disposed immediately adjacent to the at least one recess.
- the metal strip acquires the desired higher rigidity right at the beginning of the forming process.
- pairs of rollers engage in the metal strip in order to produce the respective recess in the bending area of the bent-over areas.
- a forming process is initiated, the material of the metal strip begins to flow in the bending area, whereby the material displacement is 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.
- a particularly preferred variant of the method provides that the corresponding areas of the flat metal strip gradually bent in several pairs of rolls until a maximum angle between a central part of the metal strip and the bent-up areas is reached.
- the effect can be achieved in several roller pairs that the simultaneous bending of the corresponding areas and engagement of the rollers for generating or spreading the puncture facilitates the formation of a region of lesser material thickness.
- the puncture-widening roller of each pair of rollers first engages with the bent portion (s) of the metal band 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 °.
- this angular range is particularly suitable. In this area the effect is exploited that simultaneous bending of the corresponding areas and penetration of the rolls into the material of the metal strip to produce regions with a lower material thickness leads to a facilitation of the lateral shifting of the material.
- 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 located 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 accumulation of material can occur, which may eventually generate 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. 2 shows a section through a pair of rollers of the roll forming of Fig. 1 along the line INI
- FIG. 5 shows a section through a pair of rollers of the roll forming of Fig. 1 along the line V-V and
- Fig. 6 section through a pair of rollers of the roll forming of Fig. 1 along the line Vl-Vl.
- the roll forming 1 shows a side view of a roll forming installation 1 for carrying out the production 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 shown in Fig. 2. 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 regions 12.1, 12.2 to run with lower material thickness, and the first recesses, ie areas with reduced material thickness 12.1, 12.2, generate.
- the lower roller 2.2 two projections 10.1, 10.2.
- the projections 10.1, 10.2 are very narrow, so that only narrow grooves are inserted into the metal strip 7 by the first pair of rollers 2.1, 2.2. be pressed. To the ends of the roller 2.2, 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. Outwardly, the diameter of the upper roller 2.2 increases continuously, so that the roller 2.2 in the outer region is also frustoconical.
- 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 NI-III of Fig. 1.
- the lower roller 3.2 again circumferential projections 11.1, 11.2.
- 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 of FIG. 2.
- the distance between the inner edge of the circumferential projections 11.1, 11.2 is identical to the distance of the inner edges of the circumferential Projections 10.1, 10.2 on the reel 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 regions of the rollers 3.1 and 3.2 may be greater than the opening angle of the frusto-conical portions of the rollers 2.1, 2.2 of Fig. 2.
- the opening angle of the frusto-conical regions 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. In Fig. 1, the maximum value of the opening angle and therefore also the maximum value of the setting angle is already reached in the pair of rollers 3.1, 3.2.
- FIG. 4 shows a section through the third roller pair 4.1, 4.2 from FIG. 1. Also in FIG. 4, only one half each of the upper roller 4.1 and the lower roller 4.2 is shown.
- the lower roller 4.2 in turn has circumferential 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 of Fig. 3.
- the width of the areas with lower material thickness 12.1, 12.2 in the longitudinal direction of flat metal bands 7 run, so is still 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.
- the positive effect described above is also achieved in this pair of rollers, that the material from the areas with a smaller wall thickness 12.1, 12.2 can be displaced laterally more easily.
- the lower roller 5.2 has a cylindrical central region with a first Diameter, to which join two more cylindrical areas with a slightly larger diameter, which engage and support the areas 12.1, 12.2 with lower material thickness of the metal strip 7, so that these areas are not deformed again. Subsequent to these areas of the lower roller 5.2 is followed by another cylindrical area with a smaller diameter, which corresponds to the first diameter.
- the ends of the lower roller 5.2 are again frusto-conical, with the diameter increasing towards the outside, so that the edge regions of the flat metal band 7 are now bent upwards.
- the upper roller 5.1 is constructed complementary thereto, ie the end portions of the upper roller 5.1 are also frusto-conical, the diameter of these truncated cones decreases towards the outside.
- Fig. 6 shows one of the last forming steps.
- the flat metal band 7 has almost reached the desired profile shape.
- This profile 8 is, for example, substantially rectangular, wherein the areas of lesser material thickness 12.1, 12.2 are arranged in two opposite sides of the profile 8.
- the profile 8 is not closed. But it can also be provided to close the profile 8 and, if necessary, to weld by means of a weld.
- both the lower roller and the upper roller in all roller pairs need not be formed in one piece. It can also be provided that the rollers are composed of several roller parts, which are arranged side by side. This is shown for example in FIG. 6. There are also lateral support rollers are provided which support the sides of the profile 8.
- additional workstations may be used to carry out further manufacturing steps, such as e.g. Punching, embossing or cutting to length of the profile, be provided.
- flat metal strip 7 is provided on a coil and fed to the roll forming 1.
- the edges 9.1, 9.2 of the metal strip 7 are bent downwards, so that a plane passing through the central part 14 of the metal strip 7 with planes that run through the bent edges 9.1, 9.2, one at a time Including installation angle.
- two on the lower roller 2.2 (see Fig. 2) arranged circumferential projections 10.1, 10.2 at the bending edge in the metal strip 7 and produce a first narrow puncture, ie an area with reduced material thickness 12.1, 12.2.
- the edges 9.1, 9.2 of the metal strip 7 are pulled a bit further down.
- the bending causes the material of the metal strip 7 to flow at the bending edge, which facilitates the lateral material displacement in the region of the recess.
- the edges 9.1, 9.2 of the metal strip 7 are further bent until the installation angle reaches a maximum value (see roller pair 3.1, 3.2).
- the width of the peripheral projections arranged on the lower rollers increases, which increases the width of the regions of reduced material thickness 12.1, 12.2.
- the circumferential projections of the lower rollers continue to engage in the region of the bending edge of the erected edges 9.1, 9.2.
- the edges 9.1, 9.2 of the metal strip 7 at each puncture of the circumferential projections of the lower roller continue to pull down. Since the maximum Aufstellwinkel should not be exceeded, the edges 9.1, 9.2 of the metal strip 7 therefore in each other pair of rollers, ie z. B. in the pair of rollers 4.1, 4.2, bent before the engagement of the circumferential projections a piece upwards. As a result, flow of the material of the metal strip 7 is generated in the region of the bending edge of the edges 9.1, 9.2, thereby facilitating the formation of the regions of lesser material thickness.
- the metal strip 7 is converted into a profile 8 (see FIG. 5).
- the edges 9.1, 9.2 of the metal strip 7 are moved in the opposite direction, i. upwards, bent over. This is followed by further forming steps until the desired profile 8 has been produced (FIG. 6).
- the process is preferably a continuous process.
- the method may also include further manufacturing steps such as punching, embossing or cutting to length profiles 8.
- further manufacturing steps such as punching, embossing or cutting to length profiles 8.
