Definitions

  • the invention is based on a tool for the mechanical processing of plates for their interconnection (clinching or the like) by means of a punch and a die according to the preamble of claims 1 and 2.
  • the sheets are first deep drawn by means of pins and die without piercing and it is then greased the edge of the bottom of the deep-drawn sheet metal sections radially against the resilient walls, creating a tight anchorage that looks outwardly similar to a rivet, which of course also optical advantages Has. Since the side walls are pivoted apart on the side facing the sheets during radial crimping, however, a difficult to control displacement of the support of the sheets on the die results.
  • the punch has a pin of smaller diameter, are deep drawn through the plates to be joined together in a blind bore of a die and squeezed so as to achieve a firm connection between the plates .
  • stamp and die existing tools are used for pressing, punching or the like. of plates, i.a. also for joining parts to plates (DE OS 19913695).
  • the service life of the tools used here corresponds to the use and the requirements of the tool material and is in many cases unsatisfactorily low.
  • the cost of producing the tools is very high, as they must have a total of a corresponding hardness in the claimed range (US Patent No. 5,177,861).
  • such hardnesses can lead to breakage of the tool, especially if an often required significant longitudinal extension is given transversely to the working direction thereof.
  • Because of the bracket is also a minimum longitudinal extension in Working direction required, ie, due to these circumstances stamp and die, with such required for a long service life hardness, have a certain tendency to fracture, such a breakage can have disastrous consequences.
  • the tool is used in mass production in the connection of sheets in motor vehicles, such defects have devastating consequences.
  • the aim is a tool with optimum life, with extremely favorable hardness and only a small tendency to breakage.
  • the tool according to the invention with the characterizing features of claim 1 or 2 has the advantage that only the part that is actually required for machining, namely the insert has the desired hardness and due to its design undergoes less or no breaking stress, while the other Part, namely the receiving part, according to its purpose of softer and may consist of elastic material.
  • the other Part namely the receiving part, according to its purpose of softer and may consist of elastic material.
  • cross-sections of the die and / or die, which transfer the labor especially are larger than those of the insert part, so that larger cross-sections of more elastic material can advantageously be present in the invention for force transmission and smaller cross-sections serve for the actual plate processing, with corresponding cross-sections material hardness.
  • the invention can thus be used either on the stamp side or on the die side, or on both sides.
  • punch and / or die are formed transversely to the drive direction (to the working direction) divided to thereby achieve a sufficient positive engagement and thus given adhesion.
  • the side walls of the recess formed as a blind opening a radial distance to the lateral surfaces of the pin of the punch and extend in the direction of movement of the punch.
  • the positive connection between insert and receiving part is advantageously carried out in which the recess or bore as a bore. is formed, in which the corresponding insert part with the end facing it can be inserted or used.
  • the edges of the insert part may be chamfered or rounded in order to achieve a simpler insertion.
  • the positive connection between insert and receiving part is formed as a press connection, d. H. a radial pressure exists between the inner wall of the recess and the lateral surface of the insert part.
  • connection between receiving part and insert is formed rotationally.
  • This rotational fit can be achieved by simply flattening the circular cross section underlying the AufEnglishung.
  • the tool is used for rivet-like joining of components such as plates, bolts, nuts or the like, with a plate using a die stamped before, stampable in the plate lost punch which is driven by serving as a tool die insert part and which remains in the plate after processing (DE-OS 19913695).
  • the tool according to the invention with tool holders in an exploded view, but without the inclusion of the same in the machine tool itself, shown, between two a stamp 1 and a die 2, two sheets 3 to be joined together are arranged.
  • the stamp 1 is down actuated and pulls with a arranged at its end pin 4, the corresponding acted portions of the sheets 3 in a recess 5 of the die 2 to crush this deep drawn sheet metal sections also radially when continuing the stroke, so that a rear engagement of the deep-drawn and crushed plate sections takes place , whereby a firm connection between the plates 3 is created by this clinching.
  • the punch 1 is arranged on a tool holder 6 in the machine tool, not shown here, and consists of two parts, namely a receiving part 7 and a pin 4 having insert 8. Due to the higher stress, the insert 8 with pin 4 has a much higher hardness 6, receiving part 7 and insert part 8 are connected to each other via a press connection 9, wherein the upper end of the insert part 8 in a recess 10 of the receiving part 7 form-fitting manner is plugged and is suitable to absorb high forces. As a rotation between insert 8 and receiving part 7 serves a flattening 11, on which in the recess 10 projecting end portion of the insert part. 8
  • the die 2 which is also arranged in a tool holder 6, is formed in two parts, consisting of a recess 5 having receiving part 12 and a pressed-in recess 5 stopper 13, for better insertion into the recess 5 on its underside a fold 14 has. On its upper side, a fold 15 may also be provided, so that finally a favorable for the production bead 16 is formed.
  • the remainder of the recess 5 is used in a known manner as a deep-drawn hole 17 of the die 2. The bottom of this deep-drawn hole 17 is thus formed by the plug 13, which is also a significant greater material hardness than the receiving part 12 of this die.
  • the tool holder 6 has in each case one connected to the machine tool base member 18, in which punch 1, or die 2 are used and held by union nuts 19, or spring plate 20, and springs 21 in their working position.
