Definitions

  • the invention relates to a device for rivet-like joining of sheets by means of clinching.
  • This working process is defined in DIN 8593.
  • a limited area is penetrated through the entire sheet stack and the material passed through is spread out to form a kind of rivet head.
  • a cut in the rivet-side BLech or all the sheets can be provided, or none of the sheets.
  • a device for clinching which has the features mentioned in the preamble of claim 1.
  • a block is provided on which the die and anvil are arranged side by side and which is moved back and forth transversely to the working direction of the stamp.
  • the object of the invention is to provide a device of this type in which a large number of push-through assemblies lying in a row can be produced in a simple manner.
  • the die and anvil can each be optimally dimensioned for themselves and can even be made of hard metal, since the die does not need to be spread out.
  • the stamps can be arranged circumferentially on a disk which does not have to be synchronized with any other moving part.
  • the device according to the invention basically comprises the elements stamp, die and anvil, which - as will be shown - can be modified to a considerable extent without deviating from the basic idea of the invention.
  • stamp 20 are uniformly attached to the circumference of a stamp wheel 22.
  • the stamps are identical to one another; their working surfaces 24 pointing in the radial direction are rectangular; but they can also be rounded on the end faces.
  • the die 32 is a block with a U-shaped profile (Fig. 3); the slot facing the stamp wheel has a width on the relevant side of the die such that the edges delimiting it cut into the metal sheets with the counter edges of the stamp. The slot widens somewhat towards the inside, as can also be seen in FIG. 3.
  • the anvil here has the shape of a roller 34, rotatably mounted in the holder 30 with a pin 36. As can be seen in Fig. 2, the roller is aligned with the slot of the die 32 behind, partially below this.
  • the roller 34 is significantly wider than the slot of the die, and the top of the die is closer to the stamp wheel 22 than the circumference of the roller 34 by a preferably adjustable dimension "a".
  • the shape of the rivet head can be influenced by the shape of the contour on the circumference of the roller 34.
  • the profiling can be designed in such a way that the part of the pressed-through material originating from the die-side sheet is laterally supported, so that its spreading is prevented without, however, hindering the spreading of the sheet or sheets on the die side. This favors the formation of high stressed rivet heads.
  • the device works as follows: If the sheet 26, 28 in the drawing are guided from the left onto the holder 30 and along the upper side of the die, they reach a point where the upper side of the sheet 26 intersects the flight circle 37 of the working surfaces 24 of the punches 20 indicated by the dashed lines.
  • the stamp wheel 22 is driven to rotate counterclockwise. Accordingly, the next arriving punch cuts two parallel slots through both sheets, starting at the intersection mentioned, in cooperation with the stationary die 32 now be taken away from the stamp.
  • the material between the two slots has been pushed through in the direction of the anvil and the dimension "a" is set so that there is an undersize with respect to the sum of the sheet thicknesses between the working surface of the die 20 in question and the circumference of the roller 34, so that the material pushed through is inevitably squeezed; the roller 34 rotates through a corresponding small angle.
  • the sheets are still conveyed by the stamp 20 until it emerges from the first joining point formed in this way. This is preferably the case when the next stamp is just beginning to cut the next joining point.
  • Both the die and the anvil are preferably made of highly wear-resistant material (hard metal). It can be seen that both can be of a fairly robust design, so that interference cannot be expected even in continuous operation.
  • Fig. 4 shows that instead of the roller 34, a rocker arm 40 which can be reset by means of a spring 38 can also be used as the anvil.
  • the die can also be designed as such a spring-resetting rocker arm according to FIG. 5.
  • each type of die shown can be combined with each type of anvil shown.
  • stamps 7 are exchangeably mounted on the stamp wheel, the stamps are combined with the stamp wheel to form a one-piece star-shaped component 44, which is preferably stiffened on both sides by support disks 46.
  • FIG. 8 and 9 show how a scraper ring 47, supported by springs 48, is arranged on a stamp wheel 22 as in FIG. 1, by means of which the joined metal sheets are pressed off by the stamps.
  • a stamp assembly 50 consisting of a center block 52, two control blocks 54 and attached to these parallel stamps 20 (only one can be seen in the drawing).
  • the center block is connected via a leaf spring 74 to an obstructing drive (arrow 56), for example a hydraulic cylinder, so that the stamp assembly can be displaced relative to a stationary control housing 60.
  • Its walls 62 carry control links 64, on which the control blocks run, are raised as a result of the bevels 66 (arrow 68), the leaf spring being deflected until they return to the starting position behind the control links.
  • the ram assembly is pressed downwards as a result of the cooperating wedge surfaces 70/71, that is, into the sheets supported by the die (not shown), and on the way back the rivet head is pushed through and formed. Behind the control links, the spring 74 lifts the stamps out of the joining points again.
  • FIG. 11 schematically shows the construction of a machine with which longitudinal seams on pipe sections can be closed.
  • a first cantilever 82 carrying a stamp wheel 22 extends to the side and a second cantilever 84 parallel to it carries the die anvil assembly.
  • the drive torque is transmitted, for example, by means of a revolving chain 86.
  • the second boom can be pivoted so far about a journal bearing 88 that a finished workpiece 90 can be removed; a hydraulic swivel drive 92 is indicated.
  • Fig. 12 shows a similar machine with two arms, but in which the conveying direction is provided transversely to the extension of the arms; With this machine, for example, several pipe sections can be axially strung together. The machine can also be used to produce longer, wider, chamfered or profiled workpieces.
  • a plurality of stamp wheels can also be placed next to one another, even with rotating stamps, each of which is assigned a die-anvil assembly; the stamps can work in phase or out of phase.
  • a system for joining a flat sheet with a corrugated sheet to a composite panel could, for example, have as many joining modules as there are connecting lines to be produced, and the joining process would take place in a single pass.
  • the punch and die cut through all the sheets. If the transverse dimension of the punch is chosen to be smaller than the distance between the die cuts, the punch-side sheet metal is not cut at first, so that the joining points which arise are fluid-tight. If the die is also not provided with cutting, but with rounded edges, none of the sheets is cut. The sheets are then clamped together at the joints without cuts.
  • the device according to the invention is also possible to design the device according to the invention as a mobile device that by hand or by means of guides along seam lines of, for example, firmly clamped or larger workpieces.
