Definitions

  • the joining tools are "open" in the direction parallel to the cuts.
  • clinching tools have also become known in which the die has a closed contour and the punch has a contour which is smaller than this, in such a way that none of the metal sheets to be joined is cut and a fluid-tight joining point is thus created.
  • Such a device is disclosed for example in DE-OS 31 06 313, Fig. 7/8.
  • the die contour is limited by its cutting parts, which are articulated on a base.
  • these tools require a relatively large amount of space, which is often not available in practice.
  • the object of the invention is to provide a joining device of the type specified in the preamble of claim 1 or 2, in which an easy to produce, little protruding die is made possible and the non-rotatable joining points in the direction parallel to the surfaces of the workpieces essentially the same tensile strength in all directions despite the oval shape.
  • the latter circumstance is important for the sheet metal designer, because he then does not have to adjust the clamping direction of the joining tools to the load of the later workpiece.
  • the stamp contour has a smaller dimensional difference with respect to the die contour in the direction of the deflection of the cutting parts than in the direction perpendicular to it.
  • the deformation of the material when passing through is accordingly anisotropic, but also in the subsequent spreading step, so that the two anisotropies essentially balance out and the joining point has an essentially constant tensile strength in all directions parallel to the sheet metal surfaces.
  • the cutting parts can be produced as simple stamped parts.
  • the cutting contour is then delimited by its end faces on the one hand, by the edge of a recess made in the anvil on the other hand, which can also be produced with little effort.
  • the limitation in the anvil causes the material to spread in a targeted manner in the direction of the resilient cutting parts. This reduces the depth of penetration of the punch and the pressure required to create a joining point.
  • the contour of the stamp and the die can be designed in such a way that the joining point on the die side results in a clearly offset oval, but on the die side at least approximately as a circular projection.
  • the cutting parts can be provided with suitable coatings to increase the service life and to prevent welding.
  • the die consists of a central anvil 18 with a recess 20, at the bottom of which the working surface 22 is located, and two cutting parts 24, which here have the shape of strong leaf springs.
  • the sheet is pushed through by the punch into the die recess, delimited by the cutting parts 24 and the anvil sections 26 on both sides of the recess 20, and when the throughput is stopped by the working surface 22 of the anvil, the material passed through flows laterally , because the cutting parts can be deflected elastically.
  • the stamp contour is oval, as can be seen in FIG. 3, and the die recess is also approximately oval (cf. FIG. 8).
  • the stamp contour is set back in relation to the die contour in such a way that neither of the two sheets is cut through when joining, and unequal in the two planes defined by the sectional planes of FIGS. 1 and 2:
  • the dimension "A” is significantly larger than the dimension "B”, and this also affects the cross-sectional shape of the finished joint connection, as shown in FIGS. 5 and 6.
  • the dimensions A and B and the working angle "C" of the stamp being matched to one another in such a way that the tensile strength of the joint connection in Direction parallel to the sheets is at least approximately the same.
  • the joining point is aesthetically satisfactory when viewed from both sheet metal sides.
  • FIGS. 1 and 2 The representation according to FIGS. 1 and 2 is largely schematic in order to explain the essentials for the invention.
  • a die designed in this way would have two major disadvantages: on the one hand, a compromise in terms of strength and elasticity must be found for the cutting parts; on the other hand, it cannot be ruled out that scraped-off chips from the workpieces will get into the gap between the anvil and cutting parts and spread the latter continuously , which of course affects the joining work.
  • the cutting parts are each deflectably supported on a cutting edge 30 of a base 32 and are held in contact with the anvil 18 by leaf springs 34.
  • the cutting parts can therefore be made of very hard material, while the leaf springs ensure almost unimpeded springing open during the material spreading phase.
  • the bearings of the cutting parts are designed with an arc-shaped support facing the punch, so that any dirt falls down from the storage area.
  • the anvil is drawn in below its working area, so that there are collecting spaces 36 for chips or other dirt; these collecting spaces are located below the bearing 30.
  • Anvil, base and leaf springs can be connected to one another by means of a rivet or the like, only the axis 38 of such a connecting element being indicated in FIG.
  • the chip formation can be significantly reduced or even completely prevented if the edges 46 of the anvil 'and the edges 48 of the cutting parts are not sharp-edged, but are rounded off.
  • FIG. 9 shows a form of the stamp in which the depth of penetration of the stamp is limited by a collar 50 which sits on the top of the stamp-side sheet.
  • This design is recommended for thin, soft sheets to prevent the displaced material from rising.
  • the press used then does not need to have a stroke limitation, but only a force limitation, which is the case with e.g. hydraulic drive is easier.
