Definitions

  • the invention is based on a tool for rivet-like connection of plates or plate sections lying on top of one another (clinching, or the like) or of plates with connecting parts (punch rivets, bolt connection, or the like) according to the preamble of the main claim.
  • the shell parts of the die are integrally connected to the die on their side facing away from the punch and also assume the function of the spring in the manner of a cantilever (GB 2069394).
  • the main disadvantage of this tool is in the high manufacturing costs of the same and the lack of flexibility in its use.
  • the tool according to the invention with the characterizing features of the main claim has the advantage that, apart from the fact that there is no clinching of the plates, that is, there is no leakage due to the connection point, the tool according to the invention can be used for clinching methods in which, owing to the arrangement and symmetrical to the central axis in particular through the use of more than two movable jacket parts, a controlled flow of the displaced plate material takes place.
  • the idea was overcome that with such a simple and extremely inexpensive rod or leaf spring that can be accommodated within a tool, there is sufficient force for the resetting of the jacket parts.
  • connection point there is the advantage of extremely inexpensive manufacture and, last but not least, the advantage of the tool being insensitive and easy to assemble.
  • the individual connecting sections While in the cross-shaped or star-shaped design the individual connecting sections cross, or at least can cross, in the ring-shaped design the individual springs branch off radially from this ring. It is therefore not a circumferential jacket-shaped ring, but a disk arranged in the parting plane of the die.
  • the crank has a minimum radius of 10 percent of the die diameter.
  • the durability and also the effectiveness of a leaf spring strongly depend on its design at the clamping point, with kink points more easily leading to spring breaks, in contrast to minimum radii.
  • the individual springs and their connecting section consist of flat material in a known manner (EP 0744231 B1).
  • This material corresponding to leaf springs is not only extremely easy to produce by punching the individual springs with a connecting section from one piece in order to be cranked and hardened thereafter, but also very easy to assemble.
  • the die is divided transversely to the drive direction in order to achieve the parting plane, i.e. the end face of the base part facing away from the working opening serves as the dividing plane.
  • the die base is designed as a bearing body, in which the jacket parts are mounted and guided and on the side facing away from the stamp, the connecting sections of the individual springs are supported on the end face.
  • radial and / or end-face grooves are provided in the die base part for accommodating the individual springs or their connecting sections.
  • the shell parts, the springs and the connecting sections are accommodated in such a way that a more or less smooth, cylindrical die is produced which is not only insensitive but is also easily exchangeable in the machine tool.
  • the jacket parts are non-detachably connected to the free ends of the individual springs. These jacket parts are supported, for example, to generate the counterforce of the joining force brought about by the stamp on the side of the die base facing away from the stamp. When evading, they then slide radially outwards on this base part, sometimes against the force of a single spring.
  • the jacket parts are attached to these sections by soldering, welding, or the like.
  • the free ends of the individual springs are bent inwards in the direction of the working opening, and the surfaces of the bent sections of the individual springs pointing in the direction of the stamp serve to support the shell parts fastened there.
  • relatively narrow surfaces can serve to accommodate correspondingly wide jacket parts, in particular if these jacket parts radially limit the working opening in total.
  • the parting plane runs between the base part and a base part serving to receive it in a machine tool, as indicated above, a completely self-contained tool is created.
  • a device connecting the parts exists between the base part and the base part.
  • the spring arrangement is advantageously anchored by the composition of the base part and base part.
  • connecting pins or the like serve as the connecting device. In addition to the connection, this also ensures that the two parts are fixed in relation to their rotational position.
  • the jacket parts can either completely form the radial wall of the working opening or they can form parts of the same, while other parts remain, depending on the desired design of the connecting node.
  • the radial path of the deflectable jacket parts is adamantly limited by stops of the die. This ensures that the displaced material undergoes cold compression and thus hardness quality that significantly increases the strength of the connection point.
  • the jacket parts are secured against falling out and the individual spring against overexpansion by such stops
  • the stamp is designed in the form of a rivet, a nut, a bolt or the like in order to remain positively and / or non-positively in the deep-drawing opening caused by it after completion of the enforcement.
  • This composite material creates an additional strength of the connection, above all, because the deep-drawing opening is filled with a positive fit and it is no longer possible to untie the connection point.
  • FIG. 1 shows a connecting tool in longitudinal section.
  • Fig. 2 is a plan view along line I-I in Fig. 1;
  • Fig. 5 shows a variant of the spring device or die
  • a working opening 3 is delimited by these jacket parts 2 and the die base part 1, into which regions 5 of plates 14 and 15 to be connected to one another are pressed by means of a stamp, so that a joint connection is produced in a known manner.
  • the die jacket parts 2 give radially outwards against the force of individual springs 6.
  • These single springs are connected via a connecting section 7 on the side facing away from the working opening 3 of the die bottom part, connected in one piece.
  • Grooves 8 are arranged in the bottom part of the die to protect and guide die jacket parts 2, as well as individual springs 6 and connecting section 7, so that the die can be inserted into the corresponding opening very simply and flush for installation in the machine tool, without jacket parts or spring parts being disruptive in the Are ways.
  • a base part 9 is connected to the base part 1 by means not shown, which covers the grooves 8 in which the connecting section 7 is arranged.
  • the spring device is held in the die and a completely and self-contained tool is created, the dimensions of which are adapted to those of the machine tool in which it can be used.
  • the jacket parts 2 are also guided in fixed sections for their evasive movement, these sections 18 connecting in the direction of the punch 4 to the die base part 1 or base part 9.
  • stops 19 are also arranged, by means of which the evasion path of the jacket parts 2 is limited, so that during the manufacturing process and when the workpiece material is displaced accordingly when the jacket parts 2 are pushed against these stops 19 and the stroke movement of the punch 4 continues, a corresponding cold deformation of the now crushed material takes place.
  • FIGS. 2 and 3 show a simple, cross-forming spring arrangement, namely with a cross-shaped connecting section 7 and the individual springs 6 arranged thereon, the individual springs 6 having crankings 13 in the drive direction of the plunger relative to the connecting section 7.
  • This With four individual springs, the spring arrangement is used to actuate four jacket parts.
  • the number of free springs is then also corresponding to the number of jacket parts, so that the connecting section or the like instead of a cross or a star. can be trained.
  • the individual springs 6 ' are bent inwards at their upper end, so that sections 11 are formed, on the surfaces of which mantle shell parts 2' are fastened, which indeed have the same task as in the variant in FIG. 1 take over, but are completely different.
  • the structure is such that these jacket parts 2 'radially delimit the working opening 3' towards the inside, but for the rest, including the bent sections 11 of the individual springs 6 ', are supported on the surface 12 of the die bottom part 1', so as to absorb the force of the stamp to be able to.
  • the die bottom part 1 ' is only shown in broken lines in order to be able to show the rear individual spring 6' or the rear jacket part 2 'in the given plan view.
  • the front single spring is not shown in the given view.
