Definitions

  • the invention relates to a joining device with a stamp tool and a counter tool and a holder with an opening for receiving the stamp tool or the counter tool. Both tools are coaxially aligned at different ends of a C-frame.
  • the known joining devices have a stamp provided with a drive and a suitable counter tool
  • Matrix which are arranged coaxially to each other, high demands being made on the coaxiality of the punch and the matrix, since the strength and the appearance of the connection produced depend to a large extent on this.
  • the coaxiality must be permanent and when the
  • Joining device can be guaranteed because of these facilities a high
  • the so-called C-frame or C-bracket serves here as a holder and counter bearing when the tools are moved, the C-bracket on the one hand having a low mass and on the other hand that of the
  • the publication DE 197 43 277 A1 describes a joining device of the type mentioned, in which two eccentric bushings are arranged in a receiving bore in the upper web of a C-bracket for holding a rivet setting tool.
  • the eccentric bushings have the same eccentricity and are rotated with a hook wrench to adjust the coaxiality or to compensate for misalignments.
  • the rotational position can be locked by means of a screw that can be inserted into the circumference of the eccentric bushing.
  • a punch rivet system is known from the article “punch riveting has a promising future in sheet metal processing” from the magazine “strips, sheets, tubes” 5/91, page 94 ff., In which the stamping tool is screwed onto the upper end of a C-bracket.
  • the invention has for its object to provide a joining device, the coaxial setting of stamping tool and counter tool can be achieved easily and inexpensively. It must be ensured that the coaxiality is permanent and when the joining device moves.
  • the joining device according to the invention also makes it possible to use different tool spacings and the use of different tools made of different materials and the use of tool holders with different diameter of the mounting hole with a C-bracket.
  • the tools can be retrofitted more easily, quickly and cost-effectively or adapted to new tasks in the event of wear or further development. This is particularly advantageous since C-brackets are very expensive. Due to the high rigidity requirements, they are usually made in one piece with the holder. Due to the separate production from two or more individual parts, the production of the entire C-frame can be made cheaper and the manufacturing time for the C-frame is shortened.
  • the objects described in the dependent claims represent advantageous developments of the object of claim 1. It is particularly advantageous to design the intermediate layer in a wedge shape, since the axial position of the stamping or counter tool can thus be influenced in one direction. It is also advantageous to provide a plurality of contact surfaces which are perpendicular to one another or are formed by the inner surfaces of a U-shaped element, so that the tool at Movements is more stable. A very advantageous versatility of the holder in relation to the distance to the counter tool is made possible if the holder and the associated end of the C-bracket are designed such that the holder can be rotated through 180 °. Further advantages of the preferred embodiments can be found in the description below.

  • the bore is at a different distance and / or a different inclination from at least two different, preferably all flat contact surfaces 6, which are simultaneously side surfaces of the holder 64. All contact surfaces 6 form the jacket of the prism.
  • the holder 64 can with each of the contact surfaces 6 on the end face 3 according to the required inclination of the Bore axis and / or the required distance of the bore axis from the end face 3 in the direction of the x-axis and / or the y-axis and / or the z-axis, so that a particularly simple adjustment of the holder and thus the stamping tool or of the counter tool is possible.
  • the end 2 of the C-bracket has a plate-shaped section 62 at the front end, which is essentially cuboid in shape and which forms the end face 3 for fastening the holder on the flat side facing the holder 64.
  • This end face 3 is at the same time the largest area of the cuboid and serves to better fasten the holder 64 to the end face 3.
  • the bores 18 for the detachable fastening of the holder 64 are provided on each contact surface 6, whereby in a preferred exemplary embodiment, analogous to the exemplary embodiment according to FIG. 6, there can be continuous openings on the opposite side of the prism through which the screws attach the holder 64 can be inserted through the end face 3.
  • the holes 18 are provided symmetrically such that when the prism is rotated through 180 ° about the x-axis, which is perpendicular to the axis of the hole 5, the prism can also be attached to the end face 3.
  • the side surfaces can have notches and, correspondingly, the end surface can have 3 lugs, the nose of the end surface in the notch of a side surface when the holder is attached to the end of the C-bracket intervenes.
  • the prism of the holder 64 can also have other base areas, for example a triangle, square or hexagon.
  • a further exemplary embodiment of the invention can consist in that one of the holders described above simultaneously forms the housing of the stamping tool.

Abstract

L'invention concerne un dispositif d'assemblage comprenant un poinçon (8), un contre-outil (25) et un support (4, 24, 34, 44, 54, 64) pourvu d'un orifice (5) destiné à recevoir le poinçon ou le contre-outil. Ces deux outils sont placés coaxialement l'un par rapport à l'autre aux différentes extrémités (2, 9) d'un étrier en C (1). L'invention se caractérise en ce que le support présente au moins une surface de contact plane (6, 7, 47) située sur la face extérieure dudit support, laquelle surface est adjacente à au moins une face frontale plane (3, 33, 43) de l'extrémité correspondante de l'étrier en C (1) et fixée sur cette face frontale de façon amovible. Au moins une pièce d'écartement (17, 22), définissant l'inclinaison et/ou l'écartement de la surface de contact par rapport à la face frontale, est placée entre lesdites surface de contact et face frontale.
