Definitions
- stretch material can be produced from all thin-layer materials such as plastic, paper, wood and metal with this device, the reworking of metal foils into the generally known expanded metal should be considered as an example below.
- Expanded metal is to be understood as meaning thin metal strips or metal foils, which are initially provided with a large number of interrupted incisions in order to then be stretched, i.e. stretched, transversely to the longitudinal direction of these incisions, with the result that the metal strips previously lying between the incisions to be stretched to a latticework. If this latticework lies on the same plane as the metal foil in the initial state, this lattice is wider and shorter than the foil of the initial situation, based on the direction of the incisions in the foil as the longitudinal direction.
- metal strips which form the webs of the lattice work, lie transversely to the plane of the lattice work, so that when the lattice work is viewed from above, the webs only appear in the thickness of the original metal foil.
- the original longitudinal incisions are converted into mostly honeycomb-like or diamond-shaped cavities of the latticework during the forming into a latticework.
- expanded metal is required for a wide variety of uses. If expanded metal is required, for example, as an explosion-preventing envelope for open flames, it is sufficient to produce it from metal foils that are only a few hundredths of a millimeter thick.
- the expanded material can be used as a filter, packaging material, carrier layer in the building industry and many other things. On the other hand, it can look the same way A very stable expanded metal can be produced from sheets up to several mm thick, which can be used, for example, as a tread in scaffolding, as a footrest or the like. Of course, many other uses are also conceivable, for example as sieves, paring knives and others.
- Machines for producing such expanded metals are therefore necessary which first make a large number of defined incisions in thin metals, i.e. metal foils, all of which have the same longitudinal direction, and then pull these metal foils apart transversely to the longitudinal direction of the incisions, which makes this metal wider, but also becomes shorter and takes the form of a honeycomb grid.
- Both rollers each have a cylindrical shape and have a plurality of annular grooves in their lateral surfaces, between which annular webs also remain.
- these webs act as cutting webs which, when they run into the grooves of the pressure roller, cause the metal foil lying between them to shear off (incisions) between the edge of the cutting webs of the cutting roller and the edge of the webs of the pressure roller.
- the cutting edges on the cutting bars of the cutting roller must be interrupted, so that when the cutting bars run into the grooves of the pressure roller, only individual sections of the cutting edges slide very close to the edges of the bars of the pressure roller and thus shear off the metal foil.
- the metal foil is pressed into the grooves of the drive roller by the webs of the cutting roller, so that there is no shearing off of the metal foil in this area.
- this obstacle was immovable, it was usually a nose-shaped contact surface. In this case, however, since there was friction between the metal foil and this contact surface, the metal strip was often deformed or torn off, or there was no stretching at all, since the material tore out of the lateral guide.
- These cutting edges must be interrupted in order not to produce a continuous cut in the longitudinal direction in the metal foil, but rather a large number of individual, interrupted cuts.
- cutting rollers are not made from a one-piece cylinder, but by lining up thin disks with alternately smaller and larger diameters on a common shaft, which is concentric to the axis of rotation of the cutting roller, so that the individual disks each have the cutting webs or the Form the bottom of the grooves in between.
- the mentioned recesses in the flanks of the cutting webs are usually produced by creating recesses in the flanks of the disks forming the cutting webs by means of a milling cutter which has a shape such that the cutout caused in the peripheral surface of the cutting web has a rectangular cross-section.
- the recesses are produced by eroding. Therefore, there was always damage to the metal foil or even wrapping around the cutting roller or the pressure roller. against this, brushes, baffles and other aids for removing the cut metal strip from the cutting unit were mostly ineffective.
- the recesses in the flanks of the cutting webs were designed differently for this reason, in such a way that their cross-section, that is to say the recess visible in the peripheral surface of the cutting web, does not have a rectangular but a trapezoidal cross-section, the base of the trapezoid being on the solid cutting edge.
- the cut metal strip no longer gets caught or jammed in the cutting roller, an inclination of the trapezoidal sides of the recess relative to the base of the trapezoid of 40-75 °, in particular 45 °, having proven to be the most favorable.
- This band preferably consists of a material which has a relatively high friction compared to the material of the cut band, so that in the event that this circulating band has a higher speed than the run-up speed of the metal band, the metal band in the central region of this circumferential belt because of the good Adhesion between the metal band and belt is even pulled up.
- the aim should be that the speed of the belt matches the run-up speed of the film, which is the best way to avoid warping and damage to the film.
- toothed belts are used instead of such conveyor chains, in which at least the surface consists of rubber or rubber-like, relatively elastic material, and wherein the teeth of the toothed belt are directed outwards, so that the film at the edges in each case between the lower run of a toothed belt running over it and the upper run of a toothed belt running underneath is held and transported further, these running parallel over a certain distance in order to enable the meshing of teeth and tooth gaps of the two belts.
- fabric timing belts made from a plastic-textile mixture have proven to be advantageous.
- a tooth shape of this kind must be selected for the toothed belt in which the shape of the teeth corresponds as closely as possible to that of the tooth gaps.
- the toothed belt is sufficiently tensioned or also by mechanical support, for example by means of support devices over which the gripping debris of the toothed belt runs To strive for sufficient mutual pressure of the two belts so that the holding force of the film is sufficiently large.
- the shortening of the film in the longitudinal direction can be compensated in this way, so that at the outlet of the stretching unit, i.e. at the end of the intermeshing toothed belt, due to the shortening of the film longitudinal Just such a speed of the finished expanded metal is given as it corresponds to the speed of the toothed belt and thus the speed at which it runs out of the stretching unit.
- the speeds of these holding and conveying means logically match either the inlet or the outlet of the stretching unit with that of the material to be processed or at any point in between, a device-inherent reduction in the device The speed of the strip-like material to be processed is not given.
- FIG. 1 shows, arranged one behind the other, a cutting unit 2 and a stretching unit 3, whereby it is indicated that these two units must be arranged one behind the other with continuous passage of the film 1, but not immediately one behind the other, since in between there are other devices, for example counter, control devices, Alignment and deflection device can be interposed.
- devices for example counter, control devices, Alignment and deflection device can be interposed.
- Both cutting unit 2 and stretching unit 3 can be mounted on a uniform base frame 6 or at different locations and different base frames, depending on the requirements of the production process.
- the cutting unit 2 consists of a horizontally superimposed pressure roller 5 and a cutting roller 4, which interlock and provide the film 1 passing therebetween with a large number of individual cuts 7 arranged in the longitudinal direction.
- Cutting roller 4 and pressure roller 5 are mounted on both sides in bearing blocks 19 which are mounted on the base frame 6 and are driven by drive units, not shown, for example electric motors.
- the pressure roller 5 is located above the cutting roller 4, but the arrangement could just as well be reversed.
- the outer surface of the cylindrical cutting roller 4 has a variety of essentially annular grooves 8, between which the likewise substantially annular cutting webs 10 tower.
- the peripheral surfaces 14 of these cutting webs 10 have an approximately zigzag structure in their development, as can be seen better in FIG. 2.
- the cutting edges 11 are interrupted, which would have a continuous ring shape without the cutouts 13, as a result of which it is only possible to produce individual, interrupted cuts 7 in the longitudinal transport direction 38 of the band-shaped film 1.
- only one cutting edge 11 of each cutting web 10 is interrupted by cutouts 13.
- the cutting webs 10 are so wide that they fit exactly into the grooves 18, which are also annular in the lateral surface 9 of the pressure roller 5, so that during operation of the cutting unit 2, the cutting webs 10 of the cutting roller 4 partially protrude into the grooves 18 of the pressure roller 5 and also the ridges projecting between the grooves 18 of the pressure roller 5 into the grooves 8 of the cutting roller.
- the cutting roller 4 and the pressure roller 5 rotate together and the band-shaped metallic foil 1 passes between these two rollers, the foil 1 is sheared between the cutting edges 11 of the cutting roller and the edges of the webs of the pressure roller acting against it.
- This consists of two toothed belts 30 running into each other in the region of the edges 34 of the film 1.
- One of the toothed belts 30 is arranged above or below the film 1 and guided over at least two rollers 31 so that the lower run the upper toothed belt 30 and the upper run of the lower toothed belt 30 each run parallel to the film 1 and parallel to the other toothed belt 30.
- the toothing of the toothed belt 30 is selected so that the size of the teeth 32 corresponds to that of the tooth spaces 33, the lower run of the upper toothed belt 30 and the upper run of the lower toothed belt 30 engage because of a corresponding choice of the distance from the respective upper to the lower roll 31 due to their outward teeth 32. It is ensured by sufficient tension of the toothed belt 30 by the rollers 31 that there is a sufficiently high contact pressure of the two toothed belts 30 along the entire length of the interlocking to hold the edges 34 of the film 1 between them and not only in the longitudinal transport direction 38 and to transport but also to cause sufficient hold transversely to the transport longitudinal direction 38 for the intended extension in this direction.
- This stretching is carried out in that, when the stretching unit 3 is viewed in a top view, as shown in FIG Transport longitudinal direction 38 of the film 1, but perpendicular to the plane of the film 1.
- the upper run 39 of this belt 35 extends obliquely upwards from below the plane of the film 1, so that it forms an acute angle 40 with the longitudinal transport direction 38, which preferably increases the slope of the upper run 39 from the plane of the film 1 from 1: 2 to 1: 4, preferably 1: 3, corresponds.
- the rollers 31, by means of which this belt 35 is tensioned. are also in turn stored in bearing blocks 19 which are mounted on the base frame 6.
- this belt 35 is also driven by means of drive units, preferably electric motors, so that the upper run 39 of the belt 35 moves obliquely upward to the right, that is to say with the running direction of the film 1.
- the film 1 is grasped at its edges 34 by the pairs of toothed belts 30 and conveyed further in the longitudinal transport direction 38, the film 1 stretches transversely to the upper run 39 of the belt 35 due to the run-up of the film 1 Longitudinal transport direction, namely with increasing increase of the upper run 39 of the belt 35, which preferably has a round cross section with a diameter of the order of 25 mm.
- the speed of the belt 35 should at least correspond to that of the toothed belt 30 and plastic or rubber should be selected as the material for the belt 35 in order to ensure sufficient friction and thus entrainment between the belt 35 and to ensure the material of the film 1 to be cut.
- toothed belt 30 When choosing the toothed belt 30, it is advisable to note that not only has such a tooth profile been chosen that a mating of teeth 32 and tooth spaces 33 of the associated toothed belt 30 is ensured, but the hardness of the toothed belt material must also be carefully selected in order to to ensure a sufficient holding force against the film 1.
- the most advantageous choice here has been the choice of rubber timing belts with a hardness of around 60 shore.
- the illustrated device for producing expanded material can be used, e.g. Cut and stretch aluminum foils from 3/100 to 12/100 thick.
- the rotational speed of the toothed belt 30 and the belt 35 must be matched to the rotational speed of the cutting roller 4 and pressure roller 5. Due to the folding of the film 1 around the teeth of the toothed belt 30, the rotational speed of the toothed belt 30 is lower than the speed of the incoming cut film 1, but the extent of the reduction in the distance and height of the teeth 32 of the toothed belt 30 depends.
- the film 1 is only drawn in as far as the beginning of the stretching unit 3 in order not to hinder the display of the other parts of the device.
- FIGS. 2 and 3 contain detailed representations of the cutting roller 4.
- FIG. 2 shows a developed representation of the lateral surface 9 of the cutting roller 4, that is to say more precisely the peripheral surface 14 of the cutting webs 10 of the cutting roller 4, as they are between the annular and concentric to the axis of rotation of the cutting roller 4 Arranged grooves 8 remain, which preferably have a rectangular cross-section, as can best be seen in FIG.
- These cutting webs 10 each have two flanks 15 which, by means of the peripheral surfaces 14 of the cutting webs 10, form the annular cutting edges 11 which cooperate with the flanks of the grooves 18 of the pressure roller 5 cause the material to be cut, ie the film 1, to be sheared off.
- the cutting roller 4 and the pressure roller 5 must be assigned so close that the grooves 8 and 18 and the webs between the two rollers interpose.
- cutting roller 4 and pressure roller 5 are shown spatially separated from one another in FIG. 3 in order to facilitate the description and representation of the individual surfaces and edges.
- the recesses 13 of the circumferential surfaces 14 of the cutting roller 1 that can be seen in FIG. 2 result from the recesses 12 that can be seen in FIG. 3, as are provided in the flanks 15 of the cutting webs 10. These also protrude into the peripheral surface 14 of the cutting webs 10 and thus result in the cutouts 13.
- the shape of the recesses 12 shown in FIG. 3 is preferably obtained when the cutting roller 4, as shown in FIG. 3, consists of individual disks of alternately larger and smaller diameters, which are arranged one behind the other in the axial direction to form the cutting roller 4.
- said recesses 12 are made in the flanks 15 of the disks, which later form the cutting webs 10, by means of a disk cutter, so that the arcuate outlet of the recesses 12 results in the lower region of the flanks 15.
- these recesses 12 can also be produced in other ways, which is then mainly required is when the cutting roller 4 is not constructed from individual disks but is made from a one-piece, cylindrical part.
- FIG. 3 is a sectional view along the lines AA of FIGS. 1 and 2, that the grooves 18 of the pressure roller 5 are partially filled with rubber 17, which during the cutting of the film 1 by action by the cutting webs 10 is pressed together, but then, due to its expansion into the original state, the film 1 partially lying in the groove 18 is pressed out of it.
- these recesses 12 are so designed that its cross-section and thus the recess 13 in the peripheral surface 14 of the cutting webs 10 is trapezoidal, the base of the trapezoid lying on the line of the solid cutting edges 11.
- the sides 41 of this trapezoid of the recess 13 are preferably at the same angle 43, and preferably inclined by 40 ° to 75 °, in particular 45 °, with respect to the base 42 of the trapezoid, as shown in FIG. 5.
- the film 1 runs out of the cutting unit so easily and without cracks that both the elastic inserts in the grooves 8 of the cutting roller 4 and the wiping brushes used at the outlet from the cutting unit and other guiding devices as well as the rubber inserts the cutting rollers can only be used as further optimizations.
