Fig. 5 a, 5b, 5c are the wheel rim of aluminium alloy wheel hub of the present invention and the assembly technology figure of spoke.
The specific embodiment
See also Fig. 1 and Fig. 2.Aluminium alloy wheel hub of the present invention comprises wheel rim 1 and the spoke 2 of being located at wheel rim 1, and wherein, said wheel rim 1 is for to form a center hollow structure by aluminium alloy plate one spin forming, and its edge flange becomes a kink 11.Spoke 2 one are connected in the wheel rim hollow and separate the hollow space of wheel rim; Its bowl type structure for forming by aluminium alloy plate one spin forming; And which is provided with breather port 21 and knock hole 22; The center that said knock hole is positioned at spoke is used for the location, and said breather port is around said knock hole, and doing ventilates uses.Wheel rim 1 forms back-off shape ladder with spoke 1 through spinning and is connected, and connects as one through friction rabbling welding.
In this specific embodiment, wheel rim 1 is formed by high intensity cold rolling aluminum alloy 6061 whole spinning, and spoke 2 is formed by high intensity cold rolling aluminum alloy 6061 or 7075 shear spinnings, and spoke 1 is connected through the assembling of back-off seam spinning with wheel rim 2, and reinforces through the circumferential weld weldering.The ultra lightweighting aluminium alloy wheel hub that adopts aluminum alloy 6061 to process is following with the parameter comparison of the wheel hub that adopts aluminum alloy 6061 forgings to process:
It is thus clear that the performance of aluminium alloy wheel hub of the present invention obviously is superior to traditional forged hub, and weight obviously alleviates.
The method for making of aluminium alloy wheel hub of the present invention is following:
1, makes wheel rim
Cut suitable aluminium alloy plate earlier and aluminum alloy plate materials is rolled into the triangle hollow cylinder, shown in Fig. 3 a;
Adopt friction stir weld that said hollow cylinder docking port is welded into integral structure and rolls up and be pressed into hollow circular cylinder, shown in Fig. 3 b.
Utilize spinning machine that hollow circular cylinder is spun into the wheel rim of a center hollow structure, and with the edge flange of wheel rim, shown in Fig. 3 c;
Process seam 12 with the CNC lathe in the inboard of wheel rim, shown in Fig. 3 d.
2, make spoke
Aluminium alloy plate is cut into circle, and it is spun into one bowl of type structure, shown in Fig. 4 a;
Again on bowl type structure towards breather port 21, shown in Fig. 4 b, breather port 21 is used to the usefulness of ventilating, and also can reduce simultaneously the weight of spoke and the material of use;
Make back-off 23 in the outside of bowl type structure the rim of a bowl then, make knock hole 22 at the center, shown in Fig. 4 c, knock hole 22 is used for the location.
3, assembling spoke, wheel rim
The rim of a bowl end face with spoke links to each other with the seam end face of wheel rim earlier, shown in Fig. 5 a;
Again in the back-off position of spoke with the said wheel rim of spinning machine spinning, wheel rim is pressed at this place is absorbed in the back-off of spoke, and make wheel rim be spun into over-surplus fit structure, shown in Fig. 5 b with spoke;
Adopt the friction rabbling welding of circumferential weld that wheel rim and spoke is integrally welded in the back-off position then, shown in Fig. 5 c;
Add with full dog point socket set aluminum alloy plug more at last and stir weldering, stifled welding process hole.
Obviously, the 1st step and the 2nd step can be in no particular order, and the 1st step and the 2nd step can carry out simultaneously, also can carry out for the 2nd step earlier and carry out for the 1st step again.
Wheel rim of the present invention has adopted high intensity cold rolling aluminum alloy 6061, and material property is superior to forging 6061 aluminum alloys.Adopted cold-welding technique---friction stir welding simultaneously, guaranteed that welding is with the same intensity of mother metal.
The material of spoke is divided into 6061,7075 cold drawn aluminum alloys according to different usage conditions, especially 7075 mechanical characteristicss above common straightcarbon steel.
Because whole production link of the present invention adopts cold worked technology, has practiced thrift productive costs, has reduced energy consumption,, when gaining in strength, also saved great deal of raw materials owing to adopted spin forming and wheel rim hollow structure.And 6061 aluminum alloys after the heat treatment, polishing performance is splendid, and 6061 superior anode performances, and it is abundant especially to make outward appearance select.
The structure of wheel hub of the present invention is welded by stirring, spinning, and the CNC machined into forms; When having guaranteed run-out tolerance, also improved dynamic balance performance; Compare traditional balance block and have only 1/3 weight, improved service life greatly, also improved safety performance simultaneously.The flange technical application of wheel rim improves shock resistance greatly.This process structure belongs to mechanical cold worked category, and the production process carbon emission is zero, meets following low-carbon (LC); Environmental protection requirement, the application of high performance aluminium materials has simultaneously alleviated the weight of wheel; Alleviating of wheel weight means energy consumption minimizing at double, greatly reduces carbon emission; Along with this The Application of Technology,, the industry of high energy consumption, maximum discharge is transformed into the industry of low-carbon (LC), energy-saving and environmental protection with the manufacturing process of thoroughly overturning truck, passenger vehicle wheel hub.China's aluminium resource is abundant especially simultaneously, truck, and freight car wheel replaces steel with aluminium, meets national long term growth plan.
