Definitions

  • the invention relates to a tool set of the type mentioned in the preamble of claim 1.
  • a tool set and the joint connection that can be produced with it are disclosed in US Pat. No. 3,771,216.
  • Such joint connections have the advantage that they are fluid-tight, satisfy aesthetically and have a relatively good strength.
  • the entire cavity delimited by anvil, die, punch and anvil-side sheet metal is to be filled by the sheet metal material which has passed through.
  • the sheets to be joined are often oily or provided with other incompressible adhesions, with the result that - when the press is set to a predetermined pressure - the joint connection is inadequate.
  • a further disadvantage arises because of the inevitable tolerances of the sheet thicknesses, especially when the press is set to a predetermined stroke: the joint connection is inadequate in the case of undersize, and the die is subjected to considerable explosive forces in the case of oversize, so that it is very massive and therefore takes up a lot of space must build.
  • the object of the invention is to improve the generic tool set in such a way that even oily or otherwise soiled sheets, even those with considerable tolerances, can be safely joined and at the same time the tool set can be kept relatively small.
  • the mold assembly it is advantageous if it is built from a base into which the anvil is inserted and which has support surfaces for the die parts, because then these components can each be made of material that is suitable for the stresses that occur is best suited.
  • 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, to the foot portion 18 of the anvil 'complementary recess, so that the die parts are also securely positioned on the base. These recesses limit, together with the working section 22 of the anvil ', an annular gap 24.
  • a stamp indicated in FIG. 2 interacts, which 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 until it 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.
