Definitions

  • the invention relates to a device for rivet-like connection of sheets with the features mentioned in the preamble of claim 1.
  • Such a device is known from DE-OS No. 3106313. It has two levers next to the anvil of the die, which have the counter cutting edges.
  • the levers are pivotable about axes running transversely to the press stroke direction, and a helical compression spring acts on the two levers in such a way that they are pretensioned in the cutting position in which they rest on the anvil.
  • the linear distance between the two lever swivel axes is greater than the distance between the two punch cutting edges.
  • the die comprises a plurality of components: an anvil that tapers towards the free end extends from a base;
  • the counter-cutting elements in the form of pierced steel plates are supported on the base on the oblique side surfaces of the anvil.
  • a bolt is guided through the bore, on which spring washers also act on the outside of these plates. The distance between the plate edges, with which they are supported on the base and by which they tilt when they move sideways, is therefore greater than the distance between the cutting edges and counter-cutting edges in the cutting position.
  • the cutter body and the return leaf spring are formed in one piece, angled or bent, and the cutter bodies are supported by the anvil.
  • chips can get between the cutting parts and the parts of the anvil that support them, thereby jeopardizing the usability of the entire device. It would be more desirable that the elements with the counter cutting edges were moved exactly to the side.
  • the object of the invention is to provide a device of the same type, in which an optimal connection is created, in which a simple structure also allows inexpensive mass production, and which can finally have minimal dimensions in the direction transverse to the press stroke.
  • leaf springs can, as already mentioned, be relatively thin, there is only a minimal projection in the direction transverse to the press stroke.
  • the die comprises the anvil 14 and two cutting parts 16, which are identical to one another.
  • Anvil and cutting parts are captively connected to one another, for example by a hollow rivet 18.
  • the three components lie flat against one another, likewise in the end area facing the punch 12.
  • the anvil is excluded on the sides facing the cutting parts in such a way that it has an approximately rhombic cross-section; The free spaces created in this way enable chips that fall into it to be discharged to the outside without preventing the cutting parts from springing back.
  • the side of the cutting parts facing the anvil surfaces is supported in the foot area, where the rivet 18 is also seated, for example by means of a screw (not shown) which extends through the rivet and fastens the die to a holder which also holds it on the supports the side facing away from the stamp 12.
  • the cutting parts can rebound in the area of their free end.
  • FIG. 1 While the shape of the anvil and the stamp are shown in FIG. 1 roughly in accordance with reality, the shape of the cutting parts drawn there is not the cheapest. 2 and 3 show better shapes.
  • the stability of the device is essentially determined by the alternating stress on the cutting parts deflected during each operation. It is therefore preferred to design it in such a way that the deformation is distributed as evenly as possible over the free length - corresponding to the deflection of a beam clamped on one side under end-side loading -, resulting approximately in the profile shown in Fig. 2a.
  • the flanks of the cutting parts are cut out in a semicircular shape, or, as shown in FIG. 2c, slit-like cutouts 20 at the edge or slit-like openings 22 in the solid part of the cutting parts can be provided.
  • Such different contours with the same cutting part thickness result in different spring characteristics, and this is necessary in order to adapt to different sheet qualities: With the same sheet thickness, the cutting parts for stainless steel should be much stiffer than for aluminum, for example.
  • leaf spring assemblies can be used, e.g. are interchangeable; as can be seen, only the innermost leaf springs 24 are riveted to the anvil and form the actual cutting part, while the rest are interchangeable and the entire package is inserted into a holding block 26.
  • both cutting parts it is also possible for both cutting parts to be formed together with a foot 28 as a one-piece component cut to length from a strand, in the U-shaped profile of which the anvil is inserted.
  • the cutting part cross-section was adapted to the cheapest deformation characteristic curve according to FIGS. 2a-2c by variable width of the cutting parts.
  • the thickness of the cutting parts according to FIG. 3c can also be varied, with approximately the same characteristic being achieved as with the spring parquet according to FIG. 3a.
  • the anvil part 30 according to Fig. 4a does not have the rhombus-shaped cross-section as indicated in Fig. 1, but has a simple rectangular cross-section in the central area.
  • a roof-like slope 32 is provided on the foot side and is conveyed outward along the chips.
  • the two cutting parts need not be parallel; they can also lie on a corner and form the die with a corner anvil 36; the stamp cross-section 38 then has the shape of an equilateral, right-angled triangle.
  • the die has parallel cutting edges, but these are not located on the edge opposite the clamping or support point, but on a side edge running perpendicular to it.
  • the clamping point of the Springs are not, as in all other embodiments, essentially under the patrix, but to the side thereof, and accordingly the space under the patrix can be quite narrow.
  • two punches 12 'can also work together in a press with a common die 40; two connecting points are then obtained simultaneously for each stroke, the connection being more secure than a single connection with a correspondingly enlarged cross section.
  • FIG. 4e shows a perspective view of a detail from a complete tool, equipped with male parts P and female parts M. It can be seen that the upper tool 46 and lower tool 48 have both male parts and male parts; So that the sheets to be connected are not braced or even bent, the distance between the counter-cutting edges of the upper and lower tools is the same as the thickness of the two sheets to be connected when the tool is closed - i.e. in the deformation end position.
  • FIG. 5a shows an embodiment in which the anvil 50 is designed as a circular cylinder, the height of which can be adjusted in the direction of the arrow in relation to a base 52, for example by adjusting screws.
  • the cutting parts 54 have the shape of hollow cylinder sectors or barrel staves, which - except for the separating slots between them - completely enclose the anvil.
  • the separation slots can be designed in different numbers and different slot widths.
  • the cutting parts 54 are inserted or clamped in corresponding cutouts in the base 52.
  • the cutting parts can be made by slitting a sleeve or consist of individual segments.
  • stamp 56 in the form of a simple circular cylinder.
  • the cross sections of anvil 50 and punch 56 are essentially congruent.
  • both sheets are cut through, and only in the area of the slits between the cutting parts do the pressed material slugs still hang on the surrounding sheet metal.
  • the stamps can be provided with recesses in the area of the die slots so as not to constrict the remaining connecting webs.
  • connection point there is only a different outline shape of the connection compared to FIGS. 1 to 4a or 4b.
  • the stamp with cross-sectional dimensions 58 which are reduced by approximately twice the thickness of the sheet pressed through compared to the homologous dimensions of the anvil, the sheet is pressed through, but not cut, so that it is in the finished connection like a push button in the other Tin sits.
  • Such a design enables the connection point to remain fluid-tight.
  • the circular cylindrical shape is of course by no means mandatory, and other polygonal contours are also conceivable, for example square or hexagonal (cf. FIG. 5b for the matrix of a square connection point).
  • One die each with ejectors 60 - z. B. in the form of spring-loaded pins and an associated male with ejectors 60 are mounted on circular bases 62 of the same diameter.
  • the ejectors can also be arranged in the area independently of the matrices or patrices.
  • a male plate 64 and a female plate 66 are provided with column guides 68 and thus positioned in a reproducible manner with respect to one another. The two plates are then drilled together at the corresponding points, and the plinths 62 are then inserted into the bores 70 which are inevitably aligned, and these are rotated into a desired angular position and fixed therein. Damaged matrices or matrices can then be exchanged in a few simple steps.
  • Fig. 7 shows an example of a hand-held device equipped with a male die 80 and a female die 82.
  • the male die 86 is articulated on the female die 84 by means of bearing bolts 88, and the cylinder body 90 of a high-pressure hydraulic cylinder, the tappet 92 of which is inserted into the recess of the female die Male jaw operated in the sense of a press stroke.
  • the provision is made by the tension spring 94.
  • FIGS. 9a and 9b show a rivet-like insert N in two sections perpendicular to one another through such a connection. This insert to a certain extent represents the tip of the male part remaining in the connection.
  • Fig. 10 shows in section, largely schematic, a device with which such a connection can be made.
  • the die M is arranged in a conventional manner in a lower tool 100.
  • a slot 102 is formed above it, into which the sheets 104, 106 to be connected fit with play.
  • the lower tool has a guide channel 110 for the upper tool 108 above the die.
  • a recess 112 extending transversely to it opens into this channel 110 and serves as a magazine for the rivets N.
  • the means by which the stack of rivets in the recess 112 is conveyed are familiar to the expert and are therefore not shown here.
  • a cut extruded profile can be inserted into the recess, from which the upper tool cuts off a rivet with each press stroke.
  • Such a pliers-like design of the device has the great advantage that little space is required above and below the connection point and the connection can also be made in poorly accessible places.
  • the fact that the relative movement of the male and female dies no longer runs along a straight line, but rather along a circular arc — possibly even having a relatively small radius — does not impair the usability of the device.
  • the drive by a hydraulic cylinder is by no means mandatory; since straight guidance is not essential, a force-transmitting lever linkage can be provided, which even allows manually operated devices.
  • Fig. 8 shows an embodiment in which the male P and the female M are provided on the circumference of a disk 70 and 72, respectively, which are rotatable in the direction of the arrows. There is therefore no press in the usual sense of the word, but the two tool components are brought into operative connection with one another and with the plates 74, 76 by means of the rotary drive. In the left part of FIG. 8, the connection just established can be seen at 78.
  • the discs are located at the end of a floating shaft that is driven synchronously by a motor.
  • the disks can be coated with a friction-enhancing material between the respective male / female combinations that come into engagement, e.g. have a soft rubber pad, or can also be corrugated.
  • sheet metal used above includes not only thin sheets (less than 2 mm thick) or middle sheets (less than 4 mm thick), but also heavy plates, e.g. Aluminum 5 mm thick.
  • parts of extruded or other profiles are to be understood as sheet metal in the sense of the invention.
  • a frame made of U-profiles can be connected to a sheet metal cladding with the aid of the subject matter of the invention.
  • the two sheets to be joined do not have to have the same thickness or may consist of different materials; so you can e.g. easily connect an aluminum sheet of 3 mm thickness with a stainless steel sheet of 1 mm thickness.
