Abstract

The invention relates to a method of the cold extrusion processing of aluminum alloy automobile wheels and is characterized in that (1) a round aluminum-magnesium alloy plate is taken; (2) annealing treatment of the aluminum-magnesium alloy plate is carried out; (3) cold extrusion of the aluminum-magnesium alloy plate which goes through the annealing treatment is carried out, and one end of the plate is extruded into a round cylinder while the other end is extruded into a spoke and a hub and the edge of the spoke is provided with a circular ring or a curved surface bridge washer; (4) cool rolling is carried out on the round cylinder to form a sizing rim; (5) metal machining is carried out at the hub part to manufacture a fixing hole for connecting. Compared with the existing casting automobile aluminum wheels, the technical proposal has the advantages that firstly, the walls of the cold extrusion aluminum automobile wheels are thin, which reduces the material consumption and leads the material cost to be low; secondly, the cold extrusion forming wheel structures are compact, has good air tightness and the product qualification ratio is greatly improved; thirdly, the cold extrusion wheels are good in toughness, high in strength, resistant in collision and long in service life.

Description

The method of cold pressing aluminum alloy automobile wheel
Technical field
The present invention relates to the processing method of automotive wheel, particularly relate to the method for cold pressing aluminum alloy automobile wheel.
Background technology
Existing automotive wheel is to adopt steel made mostly, and cost is lower, but the shortcoming of its existence has: the one, and Heavy Weight, the oil consumption of travelling is big, and the weight of people through 1 kilogram of the every increase of test wheel is arranged, and just is equivalent to that loading capacity increases by 25 kilograms on the car; The 2nd, steel easily get rusty, and service life is short.So people have developed automobile aluminium wheel, but existing automobile aluminium wheel adopts low pressure casting or pressure casting method processing, and the aluminium wheel one that these two kinds of methods are produced is a wall thickness, and consumptive material is big; The 2nd, foundry goods has pore, because existing automobile does not have the inner tube of a tyre mostly, requires cover tire and wheel that very high air-tightness is arranged, and the wheel if leachy wheel leaks gas is exactly scrapped wheel, so casting aluminum vehicle wheel qualification rate is low; The 3rd, casting aluminum vehicle wheel intensity difference, cracked easily after being impacted.
Summary of the invention
The objective of the invention is provides a kind of wall thin material to economize in order to overcome the shortcoming that prior art exists, dense structure, and air-tightness is good, intensity height, the method for the cold pressing aluminum alloy automobile wheel of good toughness.
The technical scheme of cold pressing aluminum alloy automobile wheel method of the present invention is: it is characterized in that:
1., get the almag plate of a circle;
2., to the annealed processing of almag plate;
3., the almag plate after the annealing in process carried out one of cold extrusion be extruded into circular cylinder, the other end is extruded into spoke and wheel hub, there are annulus or curved surface ring in the spoke edge;
4., circular cylinder is carried out cold rolling and make the typing wheel rim;
5., carrying out metalworking at hub portion makes and is connected and fixed the hole.
The method of cold pressing aluminum alloy automobile wheel of the present invention is compared with existing casting of automobile aluminium wheel, has following advantage: the one, and cold extrusion aluminum alloy automobile wheel wall is thin, and consumptive material is economized, and the cost of material is low; The 2nd, through cold extrusion shaped wheel dense structure, air-tightness is good, and product percent of pass improves greatly; The 3rd, cold extrusion wheel good toughness, intensity height, impact resistance, long service life.
Description of drawings
Fig. 1 is an aluminium alloy plate schematic diagram of the present invention;
To be the present invention carry out schematic diagram after the cold extrusion to aluminium alloy plate to Fig. 2;
Fig. 3 is the aluminum alloy automobile wheel schematic diagram that the present invention finalizes the design.
The specific embodiment
The present invention relates to the method for cold pressing aluminum alloy automobile wheel, as Fig. 1, Fig. 2, shown in Figure 3, its major technology is characterised in that:
1., get the almag plate 1 of a circle;
2., to the annealed processing of almag plate;
3., the almag plate after the annealing in process carried out one of cold extrusion be extruded into circular cylinder 2 shapes, the other end is extruded into spoke 3 and wheel hub 4, there are annulus 5 or curved surface ring 6 in the spoke edge; If annulus 5 needs to make curved surface ring shape through cold rolling.
4., circular cylinder 2 is carried out cold rolling and make typing wheel rim 7;
5., carry out metalworking in wheel hub 4 parts and make structures such as being connected and fixed hole 8.
The method of cold pressing aluminum alloy automobile wheel of the present invention is with existing casting method production Aluminum wheels of automobiles compare, have following advantage: the one, cold extrusion aluminum alloy automobile wheel wall is thin, the consumption Material is economized, and the cost of material is low; The 2nd, through cold extrusion shaped wheel dense structure, air-tightness is good, product Qualification rate improves greatly; The 3rd, cold extrusion wheel good toughness, intensity height, impact resistance, service life Long.
