Definitions

  • the present invention relates to a joint for Blechumformmaschine for connecting two abutting edges in a sheet metal forming part and a passage in a sheet metal forming part which is parallel to the sheet plane and formed by lateral bending of the sheet.
  • ⁇ For this purpose were previously only known in the prior art "dovetails" known. However, these have the decisive night part that they could be joined only by a movement in the third dimension, outside the plane of the sheet. This is at the geometric relationships
  • the object of the present invention is therefore also to provide a joint connection for sheet-metal parts, which allows joining in a plane without movement processes perpendicular to the sheet plane, ie in the third dimension.
  • a joint connection in which the abutting edges have rectangular punctures arranged perpendicularly to the course of the abutment edge, which have a greater width along the edge than the sheet metal tongues remaining therebetween and their trailing edge running centrally in the middle of the abutting edge has a projection which extends on the abutting edge.
  • this projection has the shape of a flat, that is obtuse, isosceles triangle whose tip points to the abutting edge.
  • the sheet metal tongues have a centrally arranged indentation on their front edge parallel to the abutting edge. This also improves the material flow.
  • the object of the invention is achieved by a passage in a sheet metal forming part, in which the sheet is provided at its two outer edges with a joint connection as described above, and the passage is made by joining this joint connection.
  • this passage can then be provided with an internal thread.
  • Figure 2 is a detail view of Figure 1, showing the design of the abutting edges more clearly.
  • FIG. 3 shows the joint connection according to the invention after joining.
  • FIG. 1 shows sheet-metal parts 10 which are each to be connected along their lateral edges to a joint connection according to the invention.
  • the respective abutting edges 12 are provided with rectangular perforations 14 arranged at right angles to the course of the abutting edge 12.
  • the punched holes 14 have a greater width along the abutting edge 12 than the sheet metal tongues 16 remaining therebetween.
  • the trailing edge 18 running parallel to the abutting edge 12 has a projection 20 in the center, which extends onto the abutting edge 12.
  • the sheet metal tongues 16 have at their front edge 22 parallel to the abutting edge 12 a centrally arranged indentation 24, which is preferably designed in the form of a gentle curvature.
  • a particular advantage of this structure is that the respective abutting edges are formed identically, they are merely offset in such a way that always sheet tongues 16 from one side to recesses 14 from the other side.
  • Fig. 2 shows a more detailed representation of this design, while in the middle of Fig. 1 it can be seen how the two abutting edges 12 are adjacent to each other before the beginning of the joining process. It should be noted that in this state, the sheet metal tongues 16 protrude into the recesses 14 in such a way that between the lateral boundaries of the sheet metal tongues 16 and the recesses 14, a free space 24 remains.
  • the sheet 10 is provided with substantially rectangular cutouts 14 along the two abutting edges 12, which are to form the seam later. hen, so that wider cutouts 14 alternate with interposed thinner tongues 16, the side edges parallel to the direction in which the two abutting edges of the sheet 10 are pushed towards each other.
  • the sheet 10 is not cut parallel to the course of the seam in the "bottoms" of the cutouts 14 but has a flat tongue 20 protruding onto the joint, projecting in the joining direction like a flat triangle, this protruding point preferably having an angle of greater
  • the tongues 16 projecting between the recesses 14 are likewise not cut off parallel to the course of the abutting edge 12, but instead have corresponding indentations 24. These indentations 24 are preferably curved so as to be curved inwards, so that a concave arc is formed ,
  • the solution according to the invention makes it possible to produce a kind of "dovetail jointing" merely by movement in the sheet metal surface.
  • the two abutting edges 12 of the respective metal sheet 10, which each have identical but staggered shapes, can only be pushed into one another in the sheet metal plane possible, since the tongues 16 are always a bit thinner than the recesses 14 located therebetween.
  • the curved bulges 24 of the tongues 16 strike the flat tips 20 at the base of the recesses 14, as shown in FIG 1.
  • the further joining movement in the impact direction then causes the front ends of the tongues 16 to widen and swerve to the side, since this takes place simultaneously at both abutting abutting edges 12, finally forms one suitable Hi Intersection, through which the two sheets 10 fixed be connected and can absorb the surprisingly high forces against the joining direction, before it breaks.
  • FIG. 3 The final state of such a joint connection is shown in Fig. 3.
  • the same reference numerals designate here the same components, only just after the corresponding deformation.
  • a "true" dovetail connection has formed.
  • the present invention is suitable for all sufficiently ductile materials. So it is not only, as shown here, suitable for sufficiently ductile steel sheet, but also for light metal sheets, sheets of copper and copper alloys and even for plastic materials, always provided that the material has sufficient ductility to the flow of the tongues 16 on impact to ensure the projections 20.
  • the present invention for the first time teaches the design of the abutting edges 12 of the joint in such a form in which wider cutouts 14 are provided, engage in the thinner tongues 16, so that between them a great game 26th given is.
  • the recesses 14 is then a pointing in joining direction triangular elevation 20 provided with a tip in which the two sides of the triangle meet at an angle of preferably less than 90 ° to each other.
  • the tongues 16 each have a central indentation 24, which abuts the tip of the triangular projections 20 during the joining, so that the tongue 16 respectively begins at its front edge to flow apart laterally, whereby a corresponding undercut is created in the play area 26, and the finished joint connection, as shown in Fig. 3, similar to a conventional dovetail jointing.

Abstract

L'invention concerne une liaison d'assemblage pour des pièces façonnées en tôle, cette liaison étant destinée à assembler deux bords d'aboutement (12) d'une pièce façonnée en tôle. Selon l'invention, avant la réalisation de la liaison d'assemblage, les bords d'aboutement (12) présentent des découpes (14) rectangulaires disposées à angle droit par rapport au sens du bord d'aboutement (12), la largeur de ces découpes (14) le long du bord étant supérieure à la largeur des languettes de tôle (16) formées entre celles-ci, et leur bord arrière (18) qui s'étend parallèlement au bord d'aboutement (12) présentant en son centre une partie saillante (20) s'étendant en direction du bord d'aboutement (12).
