Description
Technical field
The present invention relates to a kind of manufacture method of aluminium alloy wheel hub of vehicle.
Background technology
Compared to steel wheel hub aluminium alloy wheel hub, there is lightweight, heat radiation and damping performance is good, dimensional accuracy is high, the advantage such as specious, have now increasing automobile to start to adopt aluminium alloy wheel hub.Therefore the research of the machining manufacture of aluminium alloy wheel hub obtains to be paid attention to widely.
Aluminium alloy automobile hub classical production process has casting and rotary press modelling.Wherein, casting can be divided into gravitational casting and low pressure casting again, and production cost is low, production efficiency advantages of higher to use casting method production aluminium alloy wheel hub to have, but its end properties is poor; And it is good to use spinning process to manufacture aluminium alloy wheel hub end properties, but its production equipment is expensive, spended time is long.Above-mentioned two kinds of forming methods have respective unvanquishable technological deficiency.For this reason, people open up manufacture method and the manufacturing process of new aluminium alloy wheel hub.
Different according to manufacturing process, wheel hub can be divided into one chip (single piece type), two-piece type and three-chip type according to structure.One chip is placed on the forge die last time extruded (here once refer to entirety, not number of times) by overall aluminium ingot, and spoke basic styling shaping rear-wheel hub together with wheel rim becomes overall; Two-piece type separates forging by wheel rim part and spoke; Three-chip type separates forging simultaneously by spoke and wheel rim, and wheel rim is also divided into two part forgings.Wherein, the wheel rim of three-chip type must be combined into wheel rim entirety with welding and fluid sealant and avoid gas leakage, and spoke part and wheel rim must be screwed simultaneously.Adopt laser weld between the spoke of tradition multiple-piece aluminium alloy wheel hub and wheel rim, the fourth of the twelve Earthly Branches connects or the methods combining of bolted.Wherein, laser weld has that speed of welding is fast, welding precision advantages of higher, but it has, and welding equipment is expensive, energy ezpenditure is large, easily produce the shortcomings such as weld defect; The fourth of the twelve Earthly Branches connects and bolted link cost is low, easily process, but it is low in conjunction with low precision, bond strength.
For this reason, a kind of new welding technology being called friction stir welding arises at the historic moment, and it is usually used in the low-melting alloy that welding take aluminium alloy as representative, and it has, and weld seam is attractive in appearance, pollution-free, bond strength advantages of higher.Adopt agitating friction welding technology to wheel hub weld refer to spoke placed as in wheel rim by the plumb joint squeeze flow position of a high-frequency rotation, this position is made to melt fusion under high temperature action, simultaneously because this connecting portion of effect expanded with heat and contract with cold can reduce, after the cooling period so just in time spoke part is stuck in wheel rim inside accurately.The advantage of this technology is that connecting portion is more firm, and intensity is higher also more difficult to come off.Meanwhile, similar forging technology also can produce the higher effect of connecting portion molecular density.
Under normal circumstances, when carrying out the welding of tubular article hoop, the steel pipe that overall diameter be equaled extend neck interior diameter to be welded inserts extend neck to be welded, to realize its inner support.But existing when using friction stir welding to weld wheel hub, back of weld is not padded, and weld seam forms space, have impact on the attractive in appearance and dimensional accuracy of product design.Meanwhile, wheel hub is a kind of special barrel, and its special character is, the diameter of whole wheel hub is also non-constant, intermediate portion diameter is less and both sides diameter is comparatively large, causes being difficult to steel pipe to insert in welding wheel hub, in addition, there is spoke the side of wheel hub, due to the stop of spoke, after wheel hub is loaded, steel pipe can not reinstall in wheel hub, add friction stir welding difficulty, cause the hub welding method of friction stir welding to be difficult to play its superiority.
