Definitions

  • the present invention relates to a method for expanding an elongated and at least regionally flat metal element, which in each case has two opposite edge regions extending in the longitudinal direction and a central region arranged between them and provided with cuts, the edge regions of the metal element being transverse to the longitudinal direction and parallel to Surface extension of the metal element are moved apart, so that connecting sections of the central region formed by the cuts and connecting the edge regions to one another are folded.
  • Elongated and at least regionally flat metal elements are used, for example, to produce profile elements for construction, in particular upright or plaster profiles. Folding over or folding the connecting sections results in a widening of the metal element with the same amount of material. As a result of the folding, wider metal elements can thus be produced with reduced material consumption and reduced weight.
  • a particular advantage of the folding method is that no time-consuming punching is required to produce the corresponding cutouts and, in particular, there is no waste of material.
  • the cutting patterns required for the folding process can be of various types. A variety of such different cutting patterns are mentioned in the above DE 102 59 307 A1 described and illustrated. For a better understanding of the present application, the disclosure content of DE 102 59 307 A1 , in particular with regard to the specifically described and illustrated cutting patterns, expressly included in the content of the present application.
  • the metal elements are flat at least in the area of the cutting patterns. In other areas, for example also in the area of the longitudinal sides of the metal elements, the metal elements can also deviate from the flat shape. In particular, thickenings, attachments or bent areas can be formed on the longitudinal sides. For example, the metal elements can already be pre-formed as U- or C-shaped profiles. Furthermore, the metal elements can be manufactured from roll material that is bent in different ways during manufacture. The term “surface extension of the metal element” accordingly means the plane of local expansion at the point where the pulling apart and folding takes place. It should also be pointed out that when the edge areas are moved apart, parts of the central section are generally also moved.
  • the edge areas are preferably pulled apart automatically in a continuous process, as is the case, for example, in FIG DE 10 2006 010 795 A1 is described.
  • the edge areas are gripped by suitable clamping holding devices and pulled apart in opposite directions.
  • this method has proven itself in practice, there is a desire to reduce the force required to pull it apart and to have more precisely defined folding edges.
  • profile elements of the type mentioned at the beginning are mass-produced articles represent, which is manufactured at a very high speed, for example 100 to 150 m / min, and which is subject to high cost pressure.
  • the invention provides that after the cuts have been made in the central area, the edge areas are offset against one another in a first process step before moving apart by targeted application of force in a direction transverse to the surface extension of the metal element and in a subsequent second process step in the offset state are moved apart.
  • the edge areas and possibly also parts of the central area are moved at least locally in two planes offset parallel to one another.
  • the connecting sections to be folded, which are each in direct or indirect connection with both edge areas, are set up, that is, after being moved, they run obliquely from one of the two parallel planes to the other plane. This is advantageous in that when the edge areas are subsequently pulled apart, there is a favorable leverage effect, so that the force required for folding is reduced.
  • a pressing or rolling tool the pressing surface of which has a step defining the offset, can be pressed against the metal element.
  • the step can be designed as a one-sided flank between two essentially smooth sections of the pressing surface, which at least locally define two planes offset parallel to one another.
  • the step is preferably located in the area of the central section, so that the edge areas are accordingly pressed into the two planes offset parallel to one another.
  • One embodiment of the invention provides that the metal element is passed between two rotatable rollers, the outer surfaces of which have respective circumferential steps with oppositely aligned flanks. In this way it is possible to move the edge areas in one continuous pass.
  • the rollers can be rotated in opposite directions when the metal element is passed through and, in particular, driven in opposite directions.
  • the edge areas are preferably offset from one another by a directional offset which corresponds to at least 3 times and at most 7 times the thickness of the metal element. Such an offset has proven to be particularly favorable in practice.
  • an embossed pattern is embossed in the central section before or during the displacement of the edge regions.
  • Such an embossed pattern causes a stiffening of the expanded metal element and accordingly an increase in stability in the profile element produced.
  • the embossing pattern can in particular comprise reinforcing beads which define depressions.
  • the cuts of the central area are preferably arranged completely in the depressions of the embossed pattern.
  • the metal element is preferably moved in the longitudinal direction during the displacement of the edge regions and / or while the edge regions are moving apart, so that the corresponding method steps are carried out in one continuous pass.
  • the invention also relates to a device for expanding an elongated and at least regionally flat metal element, which has two opposite edge regions extending in the longitudinal direction and a central region arranged between them and provided with cuts, in particular a device for carrying out a method as described above, with a stretching unit which is designed to hold the edge regions of the metal element and to move them apart transversely to the longitudinal direction and parallel to the surface extension of the metal element, so that connecting sections of the central region formed by the cuts and connecting the edge regions to one another are folded.
  • the device comprises a straightening unit connected upstream of the stretching unit, which is designed to offset the edge regions against one another by applying force in a direction transverse to the surface extension of the metal element, transversely to the surface extension of the metal element.
  • the transverse displacement of the edge areas by means of the straightening unit results in a favorable leverage effect for the subsequent step of pulling the edge areas apart.
  • the straightening unit ensures that inaccurate kinks or incorrect kinks are avoided.
  • the straightening unit can comprise a pressing or rolling tool, the pressure surface of which has a step that defines the offset. This enables a particularly simple construction.
  • the pressing surface can have two at least substantially smooth outer sections which are arranged on both sides of the step and which form the edge regions of the metal element are assigned and, viewed at least locally, extend in two mutually offset planes.
  • the step here forms one or more flanks running between the levels.
  • the pressing or rolling tool preferably has at least one rotatable roller, on the outer surface of which the step is designed to run around.
  • a straightening unit can process roll material in motion.
  • the pressing or rolling tool comprises two rotatable rollers, between which the metal element can be passed, the outer surfaces of the rollers having respective circumferential steps with oppositely aligned flanks.
  • the edge areas and possibly parts of the central area are thus each clamped between the rollers and fixed in a reliable manner in the mutually offset planes.
  • An embossed pattern which preferably extends over the step, can be formed on the pressing surface.
  • an embossed pattern has a stiffening effect.
  • the embossing pattern can in particular comprise reinforcing beads which define depressions.
  • the cuts of the central area are preferably arranged completely in the depressions of the embossed pattern.
  • the device can comprise a feed unit, by means of which the metal element can be moved in the longitudinal direction during the displacement of the edge regions and / or during the moving apart of the edge regions.
  • the feed unit can in particular comprise a drive roller or an arrangement of several drive rollers.
  • the metal element can be made of galvanized steel, aluminum or copper, depending on the application.
  • the metal element can have a thickness of more than 0.5 mm, preferably of more than 0.6 mm.
  • Such thick metal elements can at best be expanded with great difficulty using current methods and devices. Due to the reduction in force and increase in reliability made possible by the displacement, thicker and more rigid metal elements can also be processed with a device according to the invention.
  • the stretching unit can have at least two clamping sections for holding clamping of the edge areas and a device for automatically moving the clamping sections apart. This enables the expansion process to be carried out easily and quickly.
  • the clamping sections can be designed as shown in FIG DE 10 2006 010 795 A1 is described.
  • the device comprises a pressing or rolling unit connected downstream of the stretching unit for pressing or rolling the expanded metal element flat.
  • the folds or kinks produced during folding can be leveled out in this way.
  • a device according to the invention can comprise an embossing unit connected upstream of the straightening unit for embossing an embossing pattern in the central section.
  • the straightening unit can have a combined embossing / offset roller or roller, by means of which both the edge areas can be displaced transversely to the surface extension of the metal element and an embossing pattern can be embossed in the central section.
  • the offset of the edge areas and the creation of the embossing pattern can therefore be carried out in combination at a single work station. A separate embossing unit is then not required.
  • Fig. 1 shows a detail from a flat metal element 11, which has two opposite edge regions 13 extending along a longitudinal axis L and a central region 17 arranged between them and provided with interlocking cuts 15.
  • the edge areas 13 are free of cuts, which is preferred but not mandatory.
  • the in Fig. 1 The section shown is clearly shortened compared to the actual length of the metal element 11.
  • the metal element 11 forms a long metal strip which, for example, can have a length of several 100 m.
  • the metal element 11 is already in the DE 102 59 307 A1 which are explicitly referred to.
  • the cuts 15 are arranged such that the edge regions 13 of the metal element 11 can be pulled apart at right angles to the longitudinal axis L, as in FIG Fig. 1 indicated by arrows.
  • connecting sections 19 formed by the cuts 15 are folded in the form of narrow webs along kink lines 21, so that a resulting metal element 11 with an enlarged width is produced.
  • a corresponding folding process is in the Figs. 2 to 4 shown in detail.
  • Correspondingly expanded metal elements can be used, for example, for the production of profiles, as they are, for. B. as edge protection or as stand profiles for drywall, z. B. in the form of U and C profiles can be used.
  • the edge regions 13 are not starting from the in Fig. 1
  • the basic state shown is drawn apart at right angles to the longitudinal axis L, but rather offset from one another at right angles to the surface extension of the metal element 11 in a preceding method step.
  • the shifted state is in the Figures 5 to 8 shown, where Fig. 5 a side view transverse to the longitudinal axis L, Fig. 6 a side view in the direction of the longitudinal axis L, Fig. 7 a perspective view and Fig. 8 an enlarged view of the area A in Fig. 7 is.
  • the shape of the cuts 15 of the in Figures 5 to 8 The metal element 11 shown differs slightly from the shape of the metal element 11 shown in FIG Figs. 1 to 4 Sections 15 shown, but this is not important with regard to the relocation process.
  • a device according to the invention for expanding a metal element 11 has, in addition to the straightening unit 29, a stretching unit connected downstream of the straightening unit 29, which, however, is shown in FIG Figures 9-14 is not shown.
  • the stretching unit serves to hold the edge regions 13 of the metal element 11 and to pull them apart transversely to the longitudinal axis L and parallel to the surface extension of the metal element 11.
  • the stretching unit can have clamping sections engaging the edge regions 13, as shown in FIG DE 10 2006 010 795 A1 are disclosed.
  • a device according to the invention for expanding a metal element 11 can also comprise a pressing or rolling unit downstream of the stretching unit for flattening or flat rolling the expanded metal element 11 and / or a feed unit for moving the metal element 11 along its longitudinal axis L in a feed direction R, which is shown in FIG Figures 9-14 is also not shown.
  • a device according to the invention for expanding of a metal element 11 comprise an embossing unit (not shown) connected upstream of the straightening unit 29 for generating the embossing pattern 27.
  • the straightening unit 29 comprises two rotatable press rollers 30, 31, between which the metal element 11 is passed. During the passage, the press rollers 30, 31 are rotated in opposite directions, either passively or by means of a drive.
  • the press rollers 30, 31 are preferably made of steel and have respective pressure surfaces 33 which have two smooth outer sections 35, 36 and an embossing section 39 arranged between them.
  • the embossing sections 39 of the two press rollers 30, 31 are shaped complementarily and aligned with one another so that the embossing pattern 27 is not impaired when the metal element 11 is passed through the press rollers 30, 31.
  • the smooth outer sections 35, 36 of a pressure surface 33 run at different distances from the axis of rotation D ( Fig. 10 ) so that they are offset radially.
  • a step 45 is thus formed between the smooth outer sections 35, 36 and is arranged completely circumferentially on the pressure surface 33.
  • the step 45 in the illustrated embodiment is overlaid with the embossed section 39 and accordingly has a plurality of flanks 47.
  • a further smooth section could also be provided, in which case the step 45 would preferably be designed as a single, one-sided flank.
  • the steps 45 of the two press rollers 30, 31 are designed to be complementary, so that when the metal element 11 is passed through the press rollers 30, 31, the opposite edge regions 13 are moved apart as desired across the surface extension.
  • the offset defined by the steps 45 in the illustrated straightening unit 29 is five times the thickness of the metal element 11, which has proven to be beneficial in practice.
  • the press rollers 30, 31 are spaced from one another in such a way that the metal element 11 is not or not significantly pressed ( Fig. 13 ).
  • embossed pattern 27 it is possible not to produce the embossed pattern 27 on the one hand and to move the edge regions 13 on the other hand, as described above, in different work stations, but in a single work station.
  • a work station can have a combined embossing / offset roller or roller which, due to its shape, accomplishes the offset of the two edge regions 13 and the formation of the stiffening embossed pattern 27 in one and the same work step.
  • the invention enables the connecting sections 19 to be folded with reduced expenditure of force and with more precisely defined folding edges, as a result of which the expansion of metal elements 11 is significantly simplified.
