Definitions

  • the invention relates to a method for producing fillings from so-called stretching material and an apparatus for carrying out this method.
  • Expanded material is to be understood as thin foils, mostly made of metal, paper, wood but also made of plastics, which are initially provided with a large number of individual cuts, all of which are parallel to one another, but offset, and then stretched transversely to the direction of these cuts, which creates a more or less two-dimensional latticework with, for example, diamond-shaped spaces and webs made of foils, the thickness of which corresponds to the distance between the cuts made.
  • an expanded metal can be used in very different ways: starting with very thin latticework, which can serve, for example, as explosion protection for tank containers, fire protection in general and the like, the use extends to the production of footrests , Catwalks and the like when using several mm thick sheets.
  • One of the uses of expanded material referred to below only as expanded metal also consists in producing fillers of a certain shape and size from the essentially two-dimensional latticework by means of deformation, with which containers containing liquid, explosive substances, such as fuel tanks, are subsequently filled . If such a container ignites, there is no explosion of the explosive gases accumulated in the container free space, but a normal, controlled burning of the container contents.
  • the containers are to be completely filled with the packing elements for this purpose, these packing elements have such a high proportion of cavities on that the volume for the liquid contents of the container is reduced by filling with the packing by about 1 percent to 6 percent.
  • the packing not only contain the same size and shape, but also about the same density and thus film mass, since only by a uniform distribution of the metal foil within the packing and further by a uniform distribution of the Filler in the container to be filled - due to the uniform shape of the filler - on the one hand reliably achieves the explosion-preventing effect and on the other hand the reduction in the container volume can be limited. Therefore, a manufacturing process and a device for carrying out the process are necessary, in which the changes made to the expanded metal during the reworking of the packing elements run smoothly and in a defined manner, and consequently the packing elements produced not only have the same shape and dimension externally, but also approximately same and defined interior structure.
  • a spherical shape of the filler body has proven to be suitable for the subsequent filling of motor vehicle tanks and smaller gasoline canisters, namely with a diameter of approximately 2 cm.
  • a method and a device for carrying it out according to European patent application 179044 is known for producing the expanded metal from expanded metal, in which a web of expanded metal, in particular expanded aluminum, is rolled up in the longitudinal direction to form a tubular structure, and this hollow cylindrical tube is cut into hollow cylindrical pieces which are then formed into balls.
  • This is achieved by means of a device which has a funnel-shaped sleeve, through which the sheet of expanded metal is pulled and is thereby formed into a tube strand.
  • a subsequent cutting device hollow cylindrical pieces are cut off from the tubing string and individually formed into balls in an upsetting device.
  • the aluminum foil of the expanded metal is only 60 to 80 ⁇ m thick, it is very difficult to actually produce a hollow cylindrical tube from the ribbon-shaped expanded metal and to produce hollow cylindrical pieces from it by cutting it.
  • a slight deviation of any of the process parameters, such as throughput speed, adjustment of one of the devices, etc., will either result in a structure when the hose is cut, in which the ends are squeezed together and the expanded metal is interwoven, or it will not become pure as soon as it passes through the calibration nozzle creates an annular cross-section, but an incomplete ring cross-section with material concentrations in certain cross-sectional areas.
  • the device which is used in particular to carry out this method, has, for the purpose of longitudinal transport of the strand transversely to the longitudinal direction movable plates with openings which can be moved transversely to the strand, that the free passage through the partially aligned openings can be enlarged and reduced, as a result of which the strand extending through it can be reduced in cross section and can also be clamped against the plates.
  • a gradual further transport in the longitudinal direction is then possible, which in addition to the longitudinal transport results in a mechanical consolidation of the cross section of the strand.
  • Two diametrically opposite forms of the revolver are axially movably connected to one another with respect to their bottoms, so that the pressing process for the ball in one form causes the finished ball to be ejected in the opposite form if the ball is still inside the form.
  • the calibration opening which advantageously even has an inlet funnel instead of rounded inlet edges, can have at most one opening corresponding to the full width of the metal strip, but preferably the diameter of the calibration opening is Infeed correspond approximately to half the belt width and the length of the calibration opening should also be large. This leads to wavy throws in the transverse direction of the belt and consequently to a compression from the original bandwidth to the diameter of the calibration opening, but usually not to the production of a tubular structure with a cavity in the middle of the tube, the material density only increasing, depending smaller is the smallest opening diameter compared to the bandwidth.
  • the process in this section is discontinuous due to the subsequent mechanical clamping of the strand through the converging plates in the form of individual movement steps in the longitudinal direction and subsequent opening and moving back of the plates, the process as a whole can be carried out continuously, which is particularly due to the arrangement of the molds a form turret is possible. Additional heating of the calibration opening and the guide makes it easier for the stretch material to slide through.
  • the individual forms preferably consist of a blind hole, the bottom of which forms part of the negative form for the later filler, and the opening of which is directed towards the outlet of the guide.
  • the blind hole is formed by an approximately cylindrical shape, which can be closed by a hemispherical convex bottom.
  • the application of this method in a device created in this regard proceeds as follows:
  • the expanded metal is delivered as a two-dimensional, ribbon-shaped latticework. It can be delivered from a roll are or can also be fed directly from a device arranged in front for the production of the strip-shaped expanded metal into the device for the production of packing elements.
  • this band-shaped expanded metal is first drawn through a so-called calibration opening, which consists of a passage with a circular cross-section and rounded inlet edges, which is arranged in a thick plate made of metal or a similar hard material.
  • the cross section can be reduced in the longitudinal direction of the opening, so that the opening has a conical shape, or can remain the same, so that it is essentially a cylindrical shape of the opening.
  • the axial length of this calibration opening should be at least twice its diameter.
  • This strand must now be compressed and squeezed at certain intervals transversely to the longitudinal direction. This is done in that after the calibration opening transversely to the longitudinal direction of the strand, two plates are arranged one behind the other, each having identical, approximately pear-shaped openings. However, these openings in the two plates are mirror-inverted and only partially overlapping each other, so that the longitudinal axes of the pear shape in the two plates run parallel to each other, but when covering the thick ends of the two pear shapes, the thin ends in the two plates in different Show directions.
  • openings must be dimensioned such that when the thick ends of the two pear-shaped openings cover one another Free passage arises, which is larger than the cross section of the strand of expanded metal emerging from the calibration opening, which must always run through the free passage of the two plates.
  • the clamping of the strand is released by moving the two plates relative to one another by enlarging the free passage opening again to the original dimension, and the two plates are moved together again along the longitudinal direction of the strand to the original position in order to achieve the next compression and clamping of the To be able to make strands.
  • the expanded metal is not only further compacted transversely to its longitudinal direction, but also the transverse folding of the original expanded metal tape, as had happened in the calibration opening, is finally fixed by squeezing it together. This will distribute the material in The transverse direction of the strand is set practically irreversibly, so that a redistribution could only be brought about by targeted mechanical effort.
  • this transverse compression also reduces the overall cross-section of the strand at individual points on the strand, since the compression occurs not only at a certain axial point of the strand, but also in a certain area in front of and behind this axial point of the strand takes place. Since the distance between the clamping points in the axial direction of the strand is smaller than the area in which the cross-section of the strand is affected, the entire strand is constricted in this step, albeit to different extents.
  • this further compressed strand is then introduced into a guide with a round cross-section, which corresponds in shape to the calibration opening, but has smaller cross-sectional dimensions corresponding to the reduced cross-section of the strand.
  • This guide serves to introduce the strand into the shape arranged behind it, which consists of a blind hole arranged in a metallic body, which with its open side faces the outlet of the guide.
  • the bottom of the blind hole forms part of the contour for forming the packing.
  • the length of the blind hole is to be selected so that the part of the strand located therein corresponds exactly to the amount of expanded metal which the subsequent filler body is to contain, when the strand is pushed into the bottom of the blind hole.
  • both the bottom of the blind hole and the end face of the stamp have a concave, approximately hemispherical shape, so that when the stamp is completely inserted into the blind hole, a spherical cavity is formed, onto which the strand section of the expanded metal is compressed, so that a spherical packing is created.
  • the mold is moved away from the position aligned with the guide in that not a single mold is arranged behind the guide, but rather a mold turret on which several molds are arranged in a star shape, the blind holes of which are accessible from the outside, the star turret being arranged in this way that its axis of rotation extends transversely to the longitudinal axis of the guide and intersects with it so that the individual molds can be brought into positions just behind the outlet of the guide and aligned with it by rotating the turret.
  • the turret is then rotated one position further, that is until the next mold is directly behind the outlet of the guide.
  • the shape in which the severed strand section is already located has also been moved on and should now be in alignment with the stamp, which then acts on the shape.
  • the finished packing must be pushed out of the mold by an ejector.
  • the turret should preferably be equipped with an even number of shapes and designed so that the bottoms of the opposing shapes are mechanically connected to one another and can move a certain distance in the axial direction of the blind holes.
  • the bottom of the blind hole of this shape can be moved in the direction of the center point of the turret when the stamp is pressed into the shape which is just aligned with it, with the result that the bottom of the blind hole of the opposite shape moves from the center point or away from the axis of rotation of the turret, that is to say toward the opening of the blind hole, as a result of which a packing element which is possibly still in this shape is expelled.
  • each of the floors of the Blind holes must be cushioned against the center of the turret, so that when the stamp is withdrawn from one mold, both bottoms each again assume the starting position, namely the central position between the two blind hole openings.
  • such a device can process a whole series of expanded metal strips in parallel, which would result in the calibration openings and guides often having to be arranged next to one another in metal rails and the two plates arranged immediately one behind the other also having a corresponding number of pear-shaped openings .
  • Fig. 1 the complete device for the production of spherical fillers made of ribbon-shaped expanded metal is shown in plan view, while Fig. 2 shows the same system in a side view.
  • the band 1, consisting of expanded metal first runs (from the left side) into a calibration opening 4.
  • This calibration opening 4 is more or less a funnel with an approximately circular cross section, which has a strongly rounded leading edge on the inlet side of the band 1 1 and 2, this calibration opening 4 - with the exception of the rounding of the inlet edge 25 - is shown with a cylindrical shape, while in FIG. 6 the special configuration with a tapering cross section, ie in the form of a truncated cone with rounded inlet edges,
  • the previously essentially two-dimensional tape 1 is pushed together transversely to its longitudinal direction 3 and thrown into folds and thus compressed into a strand 2 with an outer contour that is approximately round in cross section.
  • a longitudinal transport 26 is arranged after the calibration opening, which at the same time further reduces the cross section of the strand 2, but not uniformly over the entire length of the strand 2, but at individual points on the strand.
  • This longitudinal transport 26 consists of two plates 13 arranged parallel to one another and transversely to the longitudinal direction 3, each of which is provided with openings 9. These openings 9 have a pear-shaped contour, as the views of the plates 13 shown in FIGS. 4 and 5 show. These pear-shaped openings 9 thus have a thick end 11 on the one hand and a thin end 12 on the other hand. The two plates 13 can be moved parallel to one another.
  • the pear-shaped openings 9 being arranged in the plates 13 such that the axis of symmetry 10 of the pear-shaped openings 9 runs parallel to the direction of movement of the plates 13.
  • the thin ends 12 of the openings 9 in the two adjacent plates point in opposite directions.
  • the two openings 9 can never completely overlap, but only the greatest possible free passage 14 through the plates 13 can be achieved in that the two thick ends 11 of the pear-shaped openings 9 are made to coincide.
  • This largest possible free passage 14 must be at least as large as the cross section of the strand 2 after it has left the heatable calibration opening 4, since it must run through this largest possible free passage 14 in the plates 13 into the guide 5.
  • the constriction of the strand 2 at individual points in this step is so great that the stroke 16, which is at the same time the distance between the constriction points of the strand 2, is not sufficient to the original cross section of the at the points in the middle between the constriction points To receive strand 2, as it is when leaving the calibration opening 4.
  • the distance and stroke 16 between the constriction points of the strand 2 is so small that the constriction of the strand 2 at individual points results in a more or less severe reduction in cross section over the entire length of the strand.
  • the guide 5, which essentially consists of a tube piece 6 with a round inner diameter and a chamfered, rounded inlet edge 35, is somewhat smaller than the calibration opening 4, but otherwise it is very small in terms of design options (see FIGS. 3 and 6) similar. Furthermore, both with the calibration opening 4 and with the guide 5, it should be noted that the axial length of both the calibration opening 4 and the guide 5, minus the rounding of the leading edge, still corresponds at least to the outlet diameter at the end of the calibration opening 4 or guide 5.
  • the guide 5 serves to introduce the strand 2 into the mold 7 lying just behind it, which together with the base 21, which represents one half of the negative form of the later filler 24, forms a blind hole 18.
  • the Walls of the blind hole 18 later serve as a guide for a stamp 8, which is fed between the walls of the blind hole 18 onto the floor 21, and whose concavely shaped end face 28 forms the other half of the outer contour of the later filling body 24.
  • the strand 2 is first inserted into the form 7 until it stops on the bottom 21 of the blind hole 18 and then through a cutting device 15 between the pipe section 6 forming the guide 5 and cut the form 7.
  • This cutting device 15 consists of a knife 17, which shears the strand 2 against the outlet edge of the pipe section 6 forming the guide 5.
  • This change of position of the shape 7 occurs in that several shapes 7 are arranged radially on a turret 19 such that their blind holes 18 point radially outwards with the free opening.
  • the axis of rotation 20 of the turret 19 is transverse to the longitudinal direction 3 of the strand 2 and the entire arrangement and design of the turret 19 is selected so that the molds 7 are adjusted in alignment with the guide 5 and in alignment with the punch 8 by rotating the turret 19 can.
  • a mold 7, after severing the strand 2, with the section 23 located therein, can be pivoted about the axis of rotation 20 of the turret 19 such that it is aligned with the punch 8, which enters between the walls of the blind hole 18 and the section 23 between it concave end face 28 and the concave bottom 21 of the blind hole 18 forms into a ball.
  • the previously considered mold 7 with the filler 24 located therein is also moved by one rotational position and is now in the embodiment shown in FIG. 2 with four molds 7 on a turret 19 in the horizontal position with respect to the guide 5.
  • the filling body 24 now falls downwards into a collecting container 27. If this is not the case, the packing 24 must be pressed out of the mold 7.
  • the bottom 21 of the blind hole 18 is movable in the axial direction of the blind hole 18.
  • the bases 21 of two opposing shapes 7 are mechanically fixed to one another via a plunger 30.
  • the opposite base 21 moves away from it. It can thereby be achieved that when the plunger 8 is pressed into the mold 7 lying on top of the turret 19 in FIG. 2, the corresponding bottom 21 yields somewhat in the direction of the axis of rotation 20, as a result of which the bottom 21 is possibly still in the lower shape 7 lying packing 24 pressed out of this shape.
  • FIG. 3 shows a top view of a calibration opening 4 in the viewing direction of the longitudinal direction 3. This can also be a corresponding supervision of the guide 5. In both cases the free inner diameter can be seen on the one hand and the rounded inlet edge 25 or 35 on the other hand as an annular zone.
  • the tube pieces 6, through which the calibration opening 4 and the guide 5 are formed can be replaced.
  • the same also applies to the molds 7 with the associated bottoms 21. This makes it possible that not only an easier replacement of the said parts in the event of wear is possible, but also a simple retrofitting of the device with other requirements for the shape or dimensions of the packing or Intermediate products if desired.
  • the calibration opening 4 and the guide 5 can either be formed by a one-piece component of a correspondingly large axial length, as is realized here in the guide 5, or else by a multi-piece design, for example a solid component which forms the smallest cross-section as in the calibration opening 4, and an inlet funnel 31 made of thinner material.
