Definitions

  • Another previously known method is to produce light metal wheels by plastically processing a rim of a disc whereby the rim is first forged and subsequently split and compressed during a spinning process.
  • Such a method of production is shown in Norwegian patent No. 154908 and the Swedish patent publication Nos. 414592 and 414593.
  • Production of light metal wheels by plastic processing using a rim as a starting point is, however, an expensive method involving large loss of material.
  • the method gives few possibilities for designing the wheels, and therefore the method has not been widely used.
  • US-A-3822458 forming the base of the preamble of claim 1, reveals a procedure for producing a one-piece light metal wheel where in a first step a plate- or bowl-shaped blank is formed from an ingot by cutting it from such ingot; in a second step the blank is heated and warm pressed in dies of requisite cnfiguration; in a third step the plate-shaped blank is formed in a twopart die to the final configuration; and in a fourth an fifth step the finally shaped blank is split and spinforged to form the rim portions of the wheel.
  • the procedure is characterized in that the second step includes heating of the crude material to a hot rolling temperature and subsequently orbitally rolling the crude billet so as to obtain the rotationally symmetric preformed material as defined in the attached claim 1.
  • the preformed material may, after orbital rolling but before splitting, be extruded or cold forged in order to obtain a specified design for the hub of the wheel.
  • the crude material may be made from an extruded bolt of an aluminium or magnesium alloy.
  • the prior art includes production of light metal wheels by plastically forming a rim of a disc whereby the rim is first forged and subsequently split and pressed during a spinning process.
  • the requisite accuracy for the thickness and roundness of such a rim is critical to produce wheels in accordance with this known method.
  • the crude material 1 is processed by a spin-forge roller as shown in Fig. 1a into a rotationally symmetrical material 2 with a particularly specified cross-sectional geometry as shown in Fig. 1b.
  • the rotation occurs between an operatively rotating (not shown) lower implement 3 and a free running upper implement 4, a so-called "sinker".
  • the rotational axes of the two implements form a fixed angle, most often between 1 and 10 degrees.
  • the implements are shaped to give the product its characteristic form.
  • the lower implement is equipped with plungers 5 in order to facilitate handling of the billet.
  • the billet is heated to a rolling temperature dependent upon the type of its constituent material (for example, 450-520 degrees C).
  • the heated material 1 is put on the lower implement (Fig. 1a) which is then rotated.
  • the upper implement moves downwardly and begins to rotate when it meets the workpiece (material).
  • the upper implement is returned and the finished material can be taken out.
  • the orbital rolling constitutes the entire plastic processing of the hub (wheel disc) of the finished wheel product.
  • Aluminium alloys are, however, very well-suited for supplementary plastic cold processing since the alloys are very easily shaped in a soft state. Then, through various processing operations, especially cold forging, one has access to processes giving greater flexibility and many possibilities of variation with substantial freedom of design while the structural and mechanical properties are improved. The process may be conducted in one or several steps, and gives possibilities for great designing complexity, great geometric accuracy and a smooth and fine surface finish. With cold forging, designing possibilities are opened which extend well over the purely rotational symmetric. In practice, the above-mentioned methods provide great possibilities and only very slight limitations in designing freedom.
  • Figs. 2 a), b) and c examples of cold forging are shown.
  • the material 2 after the step of orbitally rolling, is pressed between an upper 6 and a lower 7 die in order to give the material a desired design.
  • this procedural step is an optional alternative, not a requisite step of the invention.
  • the rim surface is subsequently spin forged into shape in a press as shown in Figs. 4a and 4b.
  • the material is held in a rotating implement comprising upper and lower pressure dies 16 and 17.
  • a roller 12 rolls and stretches the rings 10 and 11 (Fig. 3b) (cf. Fig. 4a) outwardly to rim frame 14,15 which have different lengths (Fig. 4b).
  • This final and fourth step of the inventive process facilitates an optimal material distribution which again results in low material consumption with beneficial economy of weight. Because of improved steadiness in feeding, the spin forged surface also has an advantageous structure and quality compared with cast and machined surfaces.
  • a crude material in the form of a disc is produced (cut) from a cast or extruded billet of an AlMgSi-alloy (step 1).
  • the crude disc is heated to an appropriate hot rolling temperature of 520 degrees C and is subsequently orbitally rolled in a roller (step 2) in order to obtain a particular form and size prior to further processing (the sinker of the roller determines the form of the billet).
  • the rolled material can now be further processed in accordance with steps 3 and 4 of the inventive process. But since it is desirable to give the wheel a particular design deviating from the rotationally symmetric, the rolled material is cold forged. Following cold forging, the material is fixed to a splitting operation and is split along the material's periphery (step 3). Subsequently, the rim surface is spin forged (step 4) and after this the wheel has obtained its final form.
  • a crude material disc is made from a cast or extruded magnesium bolt of the alloy AZ31 (step 1).
  • the crude material is heated to 480 degrees C and is orbitally rolled (step 2).
  • recrystallization occurs. So that the preformed billet material will have an adequate toughness during cold forging, the material must be held at a temperature of at least 220 degrees C.
  • the material (step 3) is split and is stress annealed at 450 degrees C. Spinning of the rim surface (step 4) takes place finally at a temperature exceeding 220 degrees C.
