Definitions

  • the invention relates to a screw or rivet made of an aluminum alloy of the AlZnMgCu type for connecting components made of aluminum, magnesium or their alloys.
  • a self-punching fastening device for making a riveted joint under The use of semi-hollow rivets is known for example from WO-A-95/09307.
  • screws and punch rivets from aluminum materials are technically possible.
  • screws are made from the well-known material AA7075, with one Tensile strength of about 500 to 600 MPa is achieved.
  • An expansion of the possible uses would only be possible if the named connecting elements are manufactured economically from materials with higher strength could.
  • Well-known materials with higher strength are the alloys AA7049, 7049A, 7149, 7249, 7349, 7449 and 7055, but their manufacture is not easy.
  • WO-A-96/34993 also describes the manufacture of rivets Alloy AA7050 in the composition called 6.2% Zn, 2.2% Mg, 2.3% Cu and 0.12% Zr.
  • the object of the invention is therefore to provide an alloy with which screws or rivets can be used of the type mentioned at the outset can be manufactured easily and economically with high strength.
  • the alloy is made of 6.0 to 8.0 % By weight zinc 2.0 to 3.5 % By weight magnesium 1.6 to 1.9 % By weight copper 0.05 to 0.30 % By weight zirconium Max. 0.10 Wt% chromium Max. 0.50 Wt% manganese Max. 0.10 % By weight titanium Max. 0.20 % By weight silicon Max. 0.20 Wt% iron others individually max. 0.05% by weight, total max. 0.15 wt .-%, and the balance is aluminum and unavoidable impurities.
  • the material used according to the invention is compared to comparable high-strength materials of the group AA7xxx easier to cast and easier to process warm by pressing and rolling.
  • the corrosion resistance is also significantly better than comparable alloys according to the prior art.
  • Suitable starting materials for the production of screws and rivets are extruded rods, whereby as Pre-material for punch rivets, for example, the use of sheet metal is also conceivable.
  • the alloy When producing screws or rivets over bar stock, the alloy first becomes one Cast press bolts and the bolt after a homogenization annealing to a rod-shaped primary material pressed. After solution annealing and quenching of the primary material, this is usually caused by cold tumors processed into screws or rivets, which are then used to achieve the desired strength with sufficient Elongation can be subjected to heat curing.
  • a particularly preferred production variant which allows a higher degree of cold forming with a correspondingly increased strength and also a better one Corrosion resistance leads to a regression annealing before cold forming of the primary material into a screw or rivet at a temperature of about 180 to 260 ° C for a period of about 5 seconds to 120 minutes carried out. A short treatment time applies to a high heat treatment temperature.
  • Both screws or rivets according to the invention can be thermoset to the state T 6 or T 7 strengths up to 740 MPa can be achieved.
  • the finished heat-treated screws or rivets can be anodized, coated, painted or further protected against corrosion in another way.
  • screws can also be sealed, for example, with a Teflon or Ormocere layer.
  • sealing and gluing in accordance with the known sped-cap method is also advantageous.
  • the continuous casting was carried out for all alloys under the following conditions: lowering 6.5 to 7 m / min cooling water 75 l / min meniscus state 42 mm water level 40 cm under the mold
  • annealing was carried out at 460 ° for 6 h. This was followed by a high-temperature anneal at 470 ° / 3h + 480 ° / 18h.
  • the solution was carried out at a temperature of 470 ⁇ 3 ° C for a period of 0.5 h.
  • Table 2 shows the data of all alloys obtained on the 10 x 50 mm flat profile.
  • the heat treatment was carried out in each case as follows: solution annealing 470 ° C / 0.5 h stretch ⁇ 1% fertilizlagem ⁇ 1 day Harden Condition T 651: 130 ° C / 14h Condition T 7351: 105 ° C / 5h + 175 ° C / 7h
