Definitions

  • the invention relates to a method and a device for producing expanded metal from a material web, preferably made of metal.
  • expanded metal also called expanded metal
  • a vertically and laterally movable cutter bar is used to produce expanded metal (see, for example, US Pat. No. 3,570,086).
  • the cutter bar cuts incisions spaced apart from one another transversely to the longitudinal direction of the sheet and, in the further course of the cutting movement, simultaneously stretches the transverse strip of the web which has been released by the incisions to the required extent, the expanded metal not only (non-elastically) bent, but also is stretched.
  • the cutter bar is laterally displaced with simultaneous advance of the sheet metal web in order to form the next, offset incisions and to stretch the next transverse strip with a further vertical cutting and stretching movement.
  • the method is not applicable to thin sheet metal strips, such as. B. for the production of the lamellar grid of the packs of mass transfer columns, in which the ratio of the grid web thickness to the web width must be very small (EP-B 0 069 241). No stretch is possible and the grid webs would tear at the nodes if the known method were used.
  • a method of another type is known from US Pat. No. 4,105,724, in which a plastic film made of PVC is provided with staggered incisions, heated in a heating chamber and pulled out of the heating chamber more quickly than it is introduced, resulting in a cellular structure which is subsequently hardened by cooling becomes. It is not a expanded metal process, but a thermoplastic process. A precisely defined and uniform lattice shape is neither intended nor attainable with this method, especially since the lattice emerging from the chamber can still deform slightly before solidification during transport.
  • the devices for carrying out the above-mentioned methods are designed in accordance with the respective method sequence.
  • the device known from GB-A 2 120 138 has two pairs of sprockets which are spaced apart from one another by a material web section and driven at constant speed and which drive two chains provided with prongs. The tines of the two chains reach into the pre-perforated material web at the edges and push tabs out of the web.
  • the object of the invention is to produce expanded metal with high precision and uniformity, in particular with regard to the mesh size and grid height.
  • Mesh size and grid height should - as far as possible - be independently selectable and - once selected - the continuous production of any length of grid strip with exactly the same and exactly uniform grid structure should be guaranteed.
  • Continuous production, in particular a slip-free and non-jerky conveying of the material web or the grid strip should preferably be made possible.
  • each stitch can be shaped and stretched in exactly the same way, so that an absolutely regular grid with high precision of the mesh size and grid height is obtained.
  • the method according to the invention is particularly suitable for the production of special expanded metal meshes, in which high precision and regularity of the mesh structure (mesh size, mesh height, etc.) are important, namely the lamellar mesh used according to EP-B 0 069 241 for packings of mass transfer columns.
  • the lamellar mesh used according to EP-B 0 069 241 for packings of mass transfer columns.
  • a very thin one must be used Starting material are used, in contrast to the usual expanded metal grids, the width of the slats (grid webs 8 in Fig. 1 of the accompanying drawing) is much larger than their thickness.
  • the sheet metal strip 2 is provided with offset incisions by means of a cutting and punching device (not shown).
  • FIG. 1 The shape and position of the incisions in the (still unstretched) sheet metal web 2 can be seen from FIG. 1 (cf. also the corresponding FIG. 8 of EP-B 0 069 241).
  • These are mutually parallel cutting line sections 3 of the same length, which are enlarged in the middle of the section to form a rhombic recess 4 and are offset by half the length in relation to the incisions 3 adjacent in the longitudinal direction (conveying direction) 5.
  • 1 further shows the nodes 6, the rows 7 and columns 9 indicated by dash-dotted lines, and the four webs 8 of the expanded metal 12 to be formed, which are shown in FIG.
  • node points 6 or node surfaces 16 are understood to mean the entire transition area between the webs 8, 18, including the edges delimiting the cutouts 4, 14.
  • the grid height h can be seen from FIG. 3, the angle of inclination n of the node surfaces 16 to the grid plane 20 from FIG. 6.
  • the thickness of the sheet 2 is appropriately 0.15-0.3 mm, the width of the webs z. B. 6 mm.
  • the ratio of the width of the lattice webs 18 to their thickness is therefore considerably greater than in the case of conventional expanded metal.
  • the device for the production of expanded metal consists of three in the conveying direction 5 each around a sheet metal web or web section 21, 22 of z. B. a few tens of times the mesh size w spaced apart from each other, the sheet metal or grid web 2, 12 conveying conveyors 23, 24, 25 and a calibration means 26 for grid height adjustment.
  • the sheet metal strip 2 can be fed into the device directly from the cutting and punching device (not shown).
  • the finished grid 12 is best sheared to the desired grid length immediately after the device with the aid of a cutting device 10.
  • the (constant) conveying speed of the second conveying means 24 is increased in relation to the (likewise constant) conveying speed of the first conveying means 23.
  • the (constant) conveying speed of the third conveying means 25 is also increased compared to that of the second conveying means 24.
  • the conveying speed of the calibration means 26 corresponds to that of the previous funding 25.
  • All three conveying means 23, 24, 25 are fundamentally constructed in the same way in that they are designed to engage in the incisions 3, 4 of the material web 2 or the stitches 13, 14 of the grid web 12 that result therefrom.
  • the design of the conveying means 24, 25 is completely the same, which is why the latter is first described in more detail, through which the grating 12 runs in the finished form, but with an as yet uncalibrated height.
  • It consists of a pair of rolling elements 30, 31 that interlock with each other in the manner of gearwheels and recesses. More specifically, each of the two rolling elements 30, 31 is formed from a number of toothed disks 33-38 seated on a common shaft 32 and corresponding to the number of rows of nodes 17.
  • the grid 12 has only six rows of nodes 17, which is why only six toothed disks 33-38 are provided; in practice, however, the number is naturally higher).
  • the center planes of the toothed disks 33-38 are spaced apart from one another in accordance with the knot row spacing a.
  • the node points 16 of the first, third and fifth row of knots 17 run between the respectively converging tooth flanks 39, 40 of the first, third and fifth toothed disk pairs 33, 35, 37.
  • the tooth flanks 39, 40 of these toothed disk pairs are therefore aligned with one another transversely to the conveying direction 5.
  • the tooth flanks 39, 40 of the second, fourth and sixth disk pairs 34, 36 and 38 are offset in the circumferential direction 41 by the node column distance b from those of the first, third and fifth disk pairs 33, 35, 37 by the node surfaces 16 of the second, fourth and sixth row of nodes 17 record.
  • FIGS. 6 and 7 show how the node surface 16 runs between two interacting tooth flanks 39, 40 of a pair of disks, meanwhile the preceding node surface 16a comes to lie between the two tooth flanks 39a, 40a and the next front node surface 16b runs out of the tooth flanks 39b, 40b.
  • the teeth are designed in such a way and the mutual arrangement is such that the tooth flanks roll over the lattice node surfaces 16, which have the inclination angle n to the lattice plane 20 resulting from the lattice geometry and the stretching process generated, in a deselection process similar to an involute toothing, thus making the three-dimensional Grid is held without any impairment and at the same time is transported linear and straight.
  • the centers of the toothed disks 29 of the preceding conveying means 24 are accordingly spaced apart from one another in accordance with the larger node row spacing a there. And the tooth spacing (in the disk circumferential direction) is also smaller in accordance with the smaller node column spacing b there.
  • the no-exerting funding 23 is made somewhat simpler. It consists of a pair of rollers 28 (just like the conveying means 24, 25) which transports the sheet metal strip 2 smoothly against the pull of the second conveying means 24.
  • the rollers 28 (only schematically indicated) z.
  • the conveying means 23 is basically the same, namely designed to engage in the recesses 4 of the material web 2, like the subsequent conveying means 24, 25 which engage in the corresponding recess spaces 14 of the grid web 12.
  • the teeth of the toothed disks 29, 33-38 applies accordingly analogously to the knobs or projections 27 and recesses of the rollers 28. Accordingly, the axial distance of the knobs or projections 27 in the conveyor 23 is greater than the distance between the toothed disks 29 in the conveyor 24 and the circumferential distance of the knobs or projections 27 is smaller than that of the teeth of the toothed disks 29.
  • the toothed disks 29, 33-38 of the conveying means 24, 25 have the same number of teeth.
  • the different tooth spacing in the conveying means 24, 25 is thus, as indicated schematically in Fig. 4/5, achieved by a different disk diameter.
  • This makes it possible to drive the shafts 32 of the conveying means 24, 25 together at the same speed, simply with the aid of a chain drive 42 via sprockets 43 seated on the shafts 32.
  • the calibration means 26 for the calibration of the grid height consists of cylinder shells 44, 45 rotating at a distance corresponding to the desired grid height h, between which the grid 12 is passed.
  • the calibration means 26 is constructed in the same way as the conveying means 25, so like this it has toothed disks 46 which act on the node surfaces 16 and which - because they rotate at the same conveying speed as the toothed disks 33-38 - do not serve for pulling, but for further transport.
  • the only difference is the much larger diameter of the shafts (cylinder jackets) 44, 45 in the passage area of the grating 12, between which the calibration gap is formed with the height h, so that webs 18 projecting beyond this height are pressed back into the correct position.
  • a particularly precise calibration is achieved by stretching the grille 12 with the conveying means 25 to such an extent that it is consistently slightly higher than the calibration gap between the cylinder shells 44, 45.
  • the calibration of the grille height h is facilitated by the cutouts 4. Thanks to them namely, the webs 8 can be simply rotated about their diagonal without deforming themselves by further deforming the bending edges surrounding the node surface 16, which immediately reduces the grid height.
  • the sheet metal strip 2, which has not yet been stretched and is provided with the cuts 3, 4, is transported continuously (uniformly) with the aid of the conveying means 23 and at the same (constant) first speed as it passes through the cutting and punching device (not shown).
  • the conveyor 23 transports the belt 2 without slippage, so it holds it in the recesses 4 of the belt 2 (and in the recesses) of the counter-roller) engaging projections or knobs 27 against the pull of the faster conveying second conveying means 24.
  • the second conveying speed which is increased in relation to the first speed, but which acts as a traction means due to the speed difference, so that the web section 21 running freely between the conveying means 23/24 is gradually stretched to form a three-dimensional expanded mesh structure.
  • Free-running means that the web can deform freely. Of course, this is not countered by a merely supporting sliding surface or the like).
  • the tooth flanks of the toothed disks 29 roll over the node surfaces 16 now inclined by the stretching process, the resulting three-dimensional grid being held and transported linearly and in a straight line.
  • the calibration means 26 ensures that the grid is held and transported and, at the same time, its height is calibrated.
  • the grid is only gripped at the grid node locations, and preferably at all grid node locations, in order to ensure a uniform grid formation.
  • the tooth shape, especially the tooth width, is selected in such a way (cf. Fig. 6/7) that the tooth flanks only engage and roll over the central, flat area of the inclined node surfaces 16.
  • the adjoining lattice webs 8 can also be set as inclined surfaces 18 over four bending edges which immediately delimit the node 16. Care must be taken to ensure that all toothed lock washers are correctly adjusted and exactly aligned.
  • care must also be taken to ensure that there is always a node column 19 in engagement between the tooth flanks. Otherwise it would not be possible to hold on to the grille continuously and to transport it continuously.
  • the invention has made special use of the (known) cutouts 4 at the nodes 6 for this particularly simple production and manufacturing device.
  • the recesses 4 are in fact used for the timely unimpeded retraction and extension of the teeth of toothed disks with the largest possible diameter in the lattice structure, so that there is always a node column 9 in engagement between two tooth flanks.
  • the use of the recesses 4 with regard to the simplification and advantages in the lattice height calibration has already been pointed out above, and also the securing against slipping in the first pair of rollers 28 by means of the projections or knobs 27.
  • the grid is continuously fixed and positioned. And it is not conveyed in jerks, but steadily with the conveying speed gradually increasing in the area of the sections 21, 22.
  • the three-dimensional lattice shape that results from the pure stretching process can (of course only within certain limits) be influenced and changed by the roller shape, for example the lattice height by the calibration means 26. This enables the desired lattice to be produced with the required precision.
  • Another advantage is the high production speed that can be achieved thanks to the continuous, uniform rotation of the conveyor.
  • the manufacturing process can be interrupted at any time, and the grid can be stopped in any position and restarted immediately or after a period of time without impairing its quality.
  • the grid can thus also be produced intermittently, for example in order to be able to cut off a finished grid part when the grid is stationary.
  • the calibration means 26 can also work at a higher conveying speed than the preceding conveying means in order to act as a traction means at the same time.
  • a particularly precise calibration of the grating height is achieved according to the exemplary embodiment, the grating being stretched through the conveying means 25 to such an extent that the grating height is greater than the calibration gap width between the jackets 44, 45 and the calibrating means 26 and conveying means 25 operate at the same conveying speed.
  • the mesh size w and lattice height h which are decisive for the lattice structure can be precisely preselected using the method according to the invention.
  • the mesh size by appropriate selection of the quotient of the conveying speeds of the conveying means 24, 23 and 25, 24.
  • the grid height h by the distance (calibration gap) between the cylinder jackets 44, 45 of the calibration means 26. (The grid height increases during stretching, ie with the mesh size, can, however, be reduced with the help of the calibration agent compared to the setting that results automatically during stretching).
  • the Speed quotients set constructively.
  • the speed quotients could also be freely selectable by means of individually controlled, independently driven conveying means in order to be able to produce grids of different mesh sizes (and thicknesses) in rapid succession.
  • the device shown in FIGS. 4 to 7 can furthermore have an exchangeable feed drum, on which tape 2 provided with the cuts 3, 4 is wound, which is continuously pulled off the feed drum and fed into the conveying means 23.
  • At least the one or more acting as a traction means can also consist of a positive and negative roller which three-dimensionally represent the entire grid. Since these can practically only be produced with a relatively expensive three-dimensional erosion process, this version is particularly to be considered in the case of special grids to be formed from sheet metal webs with intricately designed incisions / recesses 3/4 or in the case of grids with grid webs to be shaped in a special way be.
  • the grating which has already been three-dimensionally preformed on the way to the pair of rollers acting as a traction means is also held and transported in this case (as in the embodiment shown in the figures) as it passes between the positive and negative rollers in the rolling process.
  • other calibration rollers are possible, e.g. B. also those that increase the grid height following the described simple grid manufacturing device 23-25.
  • positive and negative rollers can not only be used at the grid node locations, but can also be attacked on the bars and any specially designed bars.
  • the grid shape can also be calibrated, that is to say influenced by deformation between the two rollers, and the grid can thus be brought into a desired calibrated, final shape.
  • Calibration is therefore understood in the context of the invention to mean any lattice deformation, from the setting of a single lattice parameter, such as the height h, to the deformation of the entire lattice structure into a desired, precisely determined three-dimensional final shape.
  • the positive and negative rollers can also be made simpler, namely in such a way that they only engage certain parts of the grid, e.g. B. analogous to the toothed disks 33-38 only in the area of the accounts of the grid.
  • the entire three-dimensional node, including the bending points surrounding it, which form the transition to the lattice webs, is depicted in a positive and negative form in the pair of rollers.
  • the pair of rollers can also only engage on the grid webs and thereby bring them into a specifically desired shape.
  • a simple height calibration can also be accomplished with this, but also to a larger grid height.
  • a pair of rollers can also be used as the conveying means, one roller of which carries knobs engaging in the recesses 4 and the other of which has corresponding holes. Furthermore, only a rotating body provided with knobs or other projections can be used as the conveying means.
  • the use of not only simple incisions 3, but also rhombic or other, e.g. B. circular recesses 4 provided sheet metal strip achieve various advantages.
  • the method can also be carried out with a sheet metal strip cut only in the customary manner.
  • the expanded metal can also be produced from a non-metallic material, provided that the plastic deformability of the material web required for the production of expanded metal is guaranteed.
  • the funds are to transport or pull the material or lattice web continuously (evenly) at a uniform speed, therefore continuously and above all not jerkily. And the material web should be conveyed without slippage. This is because the invention is based on the knowledge that any conveyance, even slightly jerky, and any slippage can impair the uniformity and precision of the lattice structure.
  • rotating bodies preferably rotating pairs of rolling bodies (pairs of rolling bodies), are used as conveying means at constant speed, which guarantee a uniform drive.
  • the rotating bodies are designed for the slip-free drive of the material or grid web and in such a way that at least the second and further ones Funding corresponds to the lattice structure, so it does not affect it This is achieved by thinking of the lattice structure as being three-dimensionally mapped onto the circumference of the rotating body and designing the circumferential surface accordingly.
  • the grid is placed around the circumference of the rotating body and pressed into the circumferential surface.
  • roller body pair leads in the case of the preferred roller body pair to the fact that the peripheral surface of one body is designed as a positive form of the grid and that of the other body as a negative form of the grid.
  • the rolling elements are then designed so that they roll over the grid without changing the grid structure.
  • one rolling element could be placed on one side of a grating track (which has the lattice structure at the entrance to the relevant funding) and the other rolling element on the other side of the grating track, and each of the two rolling elements could then be rolled over the relevant side of the grating track , wherein the positive-form circumferential surface of one rolling element engages in the grid path and the grid path would in turn engage in the negative-form circumferential surface of the other rolling element.
  • mapping the grid structure onto the circumference of the conveyor rotating body and its rolling (in the manner of an involute) on the grid track can be realized in a wide variety of variants depending on the desired grid structure, and is therefore neither restricted on the toothed pulley arrangement and on the overall image of the grid on the rollers, but also allows a wide variety of interim solutions.
  • the circumferential surfaces can also be designed differently than exactly adapted to the lattice structure 12 which is automatically set by the train on the material web 2. Namely, they can - within certain limits - be designed according to a desired lattice structure which is different from that which is set automatically by the train Lattice structure differs. With roller circumferential surfaces designed in this way, the grid web is then shaped or calibrated in accordance with the desired grid structure as it passes through the conveying means. The reshaping or calibration can also be carried out with the help of one (or more) rotating calibration means with the same or increased peripheral speed as the preceding conveying means.
