Definitions

  • the invention relates to a connecting element from a Aluminum alloy of the type AlZnMgCu, with a shaft for Connection of components made of aluminum, magnesium or their Alloys, especially a screw or rivet.
  • a self-punching fastening device for Production of a riveted joint using semi-hollow rivets is known for example from WO-A-95/09307.
  • the invention is therefore based on the object of an alloy to provide with the connecting elements of the type with high strength simple and Have it manufactured economically.
  • 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 % Copper 0.05 to 0.30 % By weight zirconium Max. 0.30 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, max. 0.15 wt .-%, and the balance is aluminum and unavoidable impurities.
  • the material used according to the invention is opposite comparable high-strength materials of the group AA7xxx easier to cast and lighter by pressing and rolling to be processed warm.
  • the corrosion resistance is also much better than comparable alloys According to the state of the art.
  • Suitable raw material for the production of screws and rivets are extruded rods, being used as a material for Punch rivets, for example, the use of sheet metal is also conceivable is.
  • the alloy In the production of fasteners using bar stock the alloy first becomes a press bolt shed and the bolt after a homogenization annealing pressed into a rod-shaped primary material. After one Solution annealing and quenching of the primary material becomes this usually by cold forming to the connecting elements processed, which then to achieve the desired Strength with sufficient stretch of a thermoset be subjected.
  • a particularly preferred Manufacturing variant that has a higher degree of cold forming with correspondingly increased strength and also allows leads to better corrosion resistance, is before Cold forming of the raw material into a screw or rivet recovery annealing at a temperature of about 180 up 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.
  • the finished heat-treated screws or rivets can each anodized, coated, painted or according to application further protected against corrosion in another way become.
  • To improve the releasability of the connection Screws for example, also with a Teflon or Ormocere layer to be sealed. In certain cases also a seal and adhesive according to the known Sped-cap procedure advantageous.
  • each alloy there was a flat profile 10 x 50 mm and one Round bar 40 mm diameter pressed indirectly.
  • the stud temperature was about 230 to 260 ° C
  • the recipient temperature was around 300 ° C.
  • the pressing speed was about 2 to 2.8 m / min.
  • Solution annealing was carried out at a temperature of 470 ⁇ 3 ° C over 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 Stretchers ⁇ 1% Interim storage ⁇ 1 day Harden Condition T 651: 130 ° C / 14h Condition T 7351: 105 ° C / 5h + 175 ° C / 7h
