  • a method for manufacturing an aluminium alloy automobile hub comprises the following steps of:
  • the materials outside the workpiece 1 are squeezed through the spinning rollers 5 , so that after the materials are issued to lower levels, the rim 6 for spokes is formed under the mutual effect of the first spinning base 3 and the spinning rollers 5 .
  • step 2) sleeving the workpiece 1 onto a second spinning base with the opening of the workpiece 1 downward, wherein the workpiece 1 is fixed to the second spinning base by a second upper pressure head, with a side wall of the workpiece 1 being thinned by spinning through the spinning rollers 5 to finally form a hub blank by spinning.
  • strong spinning is used, which is generally divided into a cold spinning and a heat spinning. In the process, the cold spinning and the heat spinning can both be implemented.
  • the second spinning base is a mould formed by a rim, and is also called an internal model, and the spinning rollers are molded against the internal model by pressing the side wall of the workpiece or the rim.
  • the solution treatment which is conducted at a temperature of 530-540° C. for 150-180 min, comprises placing the hub blank into a cold water tank within 25 s and stirring the cold water until the temperature of the hub blank is cooled to water temperature; and wherein the aging treatment comprises placing the hub blank into an aging oven with an aging temperature of 150-170° C. for 12-15 h, and then slowly cooling the hub blank to indoor temperature with the oven; and
  • step 1) further comprising, before step 1), selecting an aluminum alloy disk with a corresponding thickness and diameter, locating and punching the aluminum alloy disk, and spinning the aluminum alloy disk spun into the workpiece 1 in a shape of a shallow hat by strong spinning. After the spinning is ended, the workpiece 1 in a shape of a shallow hat is put on the mould with the opening thereof downward.

  • a preferred embodiment of the present disclosure is as follows.
  • Step 1 selecting materials.
  • An aluminum alloy disk with a corresponding thickness and diameter is determined to be purchased according to the specification of the hub to be manufactured, and the 6-series and improved aluminum alloy sheets are used in the aluminum alloy disk.
  • Step 2 locating and punching.
  • the aluminum alloy disk in step 1 is located and punched through a punching machine, so as to determine a central point of spinning.
  • Step 3 initial spinning.
  • the spinning mould is prepared according to the specification and shape of the hub to be manufactured, and the aluminum alloy disk is firstly spun into the workpiece 1 in a shape of a shallow hat by strong spinning to form the shape as shown in FIG. 1 .
  • Step 4 reverse spinning. Opening an external mold, wherein the workpiece 1 in a shape of a shallow hat is installed in the spinning machine with an opening of the workpiece upward, the workpiece 1 is pressed by the first upper pressure head 2 in spinning, the spinning rollers 5 spin the workpiece 1 from top to bottom, and as shown in FIG. 2 , the aluminum material of the workpiece 1 after strong spinning is spun to the rim 6 for spokes to form the shape as shown in FIG. 3 .
  • Step 5 fine spinning. After the opening of the workpiece 1 is arranged downwardly, the workpiece 1 is sleeved onto the second spinning base, the workpiece 1 is fixed on the second spinning base by the second upper pressure head, and the external wall of the workpiece 1 is spun to be thinner and in a shape through the mould by strong spinning, so as to form the hub blank in the shape as shown in FIG. 4 .
  • the reason of using multi-passes spinning as steps 3 to 5 is that one-pass spinning has limited deformation due to the aluminum sheet having relatively large thickness, especially the reverse spinning is further required.
  • the thickness of the material is increased to the rim 6 of the spoke while the workpiece 1 becomes thinner.
  • the spinning forming process is then performed on the workpiece 1 , wherein the material is gradually deformed in the whole process according to the performance of the aluminum alloy to finally form the hub blank.
  • Step 6 solution and aging treatments. After the hub blank in step 5 is spun and formed, T6 solution and aging treatments needs to be conducted, wherein the solution temperature is 530-540° C. and the solution time is 150-180 min; the hub blank is placed into a cold water tank within 25 s, and the cold water is stirred, until the temperature of the hub blank is cooled to the water temperature.
  • the hub blank is placed in an aging oven, wherein the aging temperature is 150-170° C. and the aging time is 12-15 h, and then the hub blank is slowly cooled to the indoor temperature with the oven.
  • Step 7 repairing. Reconstructive repair is conducted to the hub blank by a special tool after the hub blank is slightly deformed by the solution and aging treatments, so as to comply with next machining requirement on the hub.
  • Step 8 machining.
  • the hub blank after reconstructive repair is machined in a lathe and a processing center using a special clamp, to finally manufacture the hub product as shown in FIG. 5 and FIG. 6 .
