Definitions

  • the die in many cases, is having an anvil with laterally movable jaws thereon, wherein in this case it is especially preferred that as well the anvil as the jaws at least partly are coated with the carbon layer.
  • An especially suitable coating has shown to be a carbon coating in the nature of a “diamond-like carbon”-(DLC)-coating.
  • the carbon layer is applied by plasma-coating or sputtering.
  • FIG. 1 a die according to the invention for punch riveting
  • FIG. 2 a die according to the invention for penetration staking or clinching
  • FIG. 3 the anvil of the die according to FIG. 2;
  • FIG. 4 the jaws of the die according to FIG. 2;
  • FIG. 5 the punch coated according to the invention and belonging to the die according to FIG. 2.
  • FIG. 1 is showing an embodiment according to the invention as a die for the punch riveting.
  • the corresponding die 10 is having an annular smooth exterior surface 12 facing the metal sheet parts, which are to be joined by punch riveting.
  • a die 14 is recessed, in which the joining point is formed during the punch riveting procedure.
  • the surface 12 and the die 14 according to the invention are especially coated with carbon.
  • This coating is a so-called “diamond-like carbon”-(DCL)-coating.
  • DCL diamond-like carbon
  • a plasma-coating with carbon or a coating obtained by sputtering of carbon can be used. All these methods produce an extremely thin crystalline carbon disposit on the object treated.
  • the corresponding coating can extend around the corner onto a partial surface of the lateral area of the die 10 . It is however of importance that both area, which are contacting the metal sheet to be worked, are coated.
  • FIG. 2 is showing a die 20 for penetration staking or clinching.
  • the die is consisting of a generally cylindrical anvil 22 , which is shown in FIG. 3, too, by itself having rounded front edges.
  • the upper (front) area of the anvil 22 is coated with the carbon coating DLC described above.
  • Such coating in this connection can extend, too, onto the lateral area of the anvil 22 .
  • FIG. 4 is showing the jaws 21 of the die 20 , which are coated, too, according to the invention.
  • at least the upper (front) side of the jaws 21 has to be DLC-coated. It is recommended however to coat the jaws 21 , which always are exposed to extremely high loads during the clinching or penetration staking completely in the above described manner with carbon as this is shown in FIG. 4 by the dash-dotted line.
  • FIG. 5 is showing a punch 30 , which can cooperate with the die 20 for creating a joint.
  • the punch is having especially a cylindrical projection 32 , the diameter of which is smaller than the diameter of the opening formed by the jaws 21 .
  • this cylindrical projection 32 of the punch 30 is carbon DLC-coated in the above described manner.
  • the coating here should at least extend to the front area of the cylindrical part 32 and a part of the following lateral area.
  • such coating can be applied, too, subsequently on already existing dies and punches. Further, the coating according to the invention after wear can be renewed such that instead replacing the corresponding tools simply a new coating is sufficient.
  • DLC diamond-like carbon
  • the disadvantage of the DLC-coating is consisting in the fact that the layer over the time is showing wear and therefore the adherence of aluminum again is occurring.
  • the remedy here can be a cyclic exchange of the dies as e.g. found out in the test every three days. Further, the possibility is existing to then remove the coating from the dies and renew the coating.
  • a logistical procedure has to be created, which realizes the number of circulated dies in a cost-saving manner. It is estimated that the life of a recoated die is about 60% of a new coated die. This, however, has to be shown in the practical work.
