Definitions

  • the invention relates to a tool set for connecting a plurality of sheets lying flat one above the other by means of local extrusion.
  • Such tool sets are known in different variants.
  • US-A-3,771,216 discloses a tool set consisting of a punch and a die, into the cavity of which, for example, two metal sheets are deformed in the area between the punch and die. Since the volume of the cavity of the die is constant, the stroke will only have to be set to the maximum permissible level for tolerances-related fluctuations in the sheet thicknesses, so that the die is not subjected to large explosive forces, with the result that the strength of the thinner sheets Coincidence is insufficient.
  • a tool set having the features mentioned in the preamble of claim 1 is known from US-A-3,579,809.
  • two die parts with flat end faces on facing away from each other on the outside of the anvil under tension by rubber block springs.
  • the die parts dodge, and the material of the anvil-side sheet can dodge into the opening gap.
  • the object of the invention is to modify the generic tool set in such a way that joints of the type described at the outset can be produced, with the tolerance problem also being alleviated.
  • the solution according to the invention makes advantageous use of the gap into which excess material can flow in the case of sheets with excess thickness; the press stroke can thus be set to the sheet thicknesses lying at the lower tolerance threshold, so that the joint connections always have sufficient strength.
  • grease or oil can accumulate at the bottom of the gap, which often wets sheets to be joined.
  • the mold assembly comprises a base 10 with a rectangular plan and an upper side with a V-shaped profile 12.
  • the base has a bore 14 in the center into which an anvil 16 with a foot section 18 is inserted;
  • the anvil is stepped cylindrical, but this is not essential: other layouts of the anvil (and corresponding to the die parts) are possible.
  • On the base 10 are two die parts 20 with wedge-shaped, each one of the two V-surfaces of the base supported complementary undersides; the die parts also each have a semi-cylindrical recess which is complementary to the foot section 18 of the anvil, so that the die parts are also securely positioned on the base.
  • These recesses, together with the working section 22 of the anvil define an annular gap 24.
  • a stamp 26 indicated in FIG. 2 interacts with the mold assembly and can be moved in the direction of arrow 28 by means of a press.
  • the two sheets are pushed through without being cut into the cavity delimited by the die parts, the anvil and the anvil-side sheet, finally the anvil-side sheet Sheet is deformed into the gap 24; the die parts are pressed against the top of the base by the sheet metal lying thereon, and the V-angle is dimensioned such that the die parts do not move sideways.
  • the stamp is withdrawn, the joining point remains attached to it because the die parts are lifted off the base and can move sideways, so that they detach from the joining point.
  • Leaf springs 30 are connected approximately at the line 32 to the base 10 and engage with angled ends 34 with play in corresponding recesses 36 in the die parts; these springs return the die parts to their original position. It should also be noted here that these leaf springs could be replaced by rubber springs, for example.
  • an oil drain 40 which is incorporated into the foot section of the anvil, is indicated by dashed lines and opens into an outlet channel 42 of the base.
  • Fig. 3 shows that the die parts can be provided with an undercut extending in the direction of their deflection movement, into which sheet metal material can be deformed in order to increase the strength of the joint connection.
