Abstract
The present invention relates to wheel hub manufacturing technology fields, and in particular to a kind of hollow aluminium alloy wheel hub spinning casting technique.Including following technological process：It casts turning spinning crimping welding curled edges at unsawn timber wheel hub D rings and machines application；Turning refers to leaving crimping by specified requirement by any superfluous material parts turning at wheel hub D rings and on the top of wheel hub D rings at the wheel hub D rings, notch is formed at wheel hub D rings at this time, the spinning crimping refers to being closed notch to rotary punching at crimping by spinning process, is formed between crimping and hub body at this time hollow.The present invention passes through spinning flanging process, achieve the purpose that the hollow mitigation weight of packet, it is 518.5 cm3 by hollow part volume, it is 2.7g/cm3 according to A356 density, it is computed hollow part and saves aluminium weight 1400g, in the case where not influencing Strength Safety, the lightweight of wheel hub is realized, there is excellent application prospect and market value.
Description
Technical field
The present invention relates to wheel hub manufacturing technology fields, and in particular to a kind of hollow aluminium alloy wheel hub spinning casting technique.
Background technology
As the cost of the energy such as automobile, diesel oil is higher and higher, complete vehicle weight is required to get over now with various OEM clients
Come stringenter, the lightweight requirements of vehicle are the requirements of each main engine plants, and wheel is being protected as one important safety member of vehicle
It is current each main research direction of wheel producer to carry out loss of weight design to wheel under the premise of card wheel performance.In various drops
In the measure of low oil consumption, automobile lightweight mitigates the dead weight of automobile as important measures：Wheel lightweight brings section material effect
While beneficial, energy-saving benefit is equally huge.Spinning casting is to carry out rotation punching to tread ring part on the basis of low pressure casting
Pressure changes the internal structure of tread ring position metal, and molecule is in more highdensity fibrous arrangement, has higher compared to conventional cast
Mechanical property performance, it is more preferable to show as intensity higher, toughness.At the D rings of traditional wheel hub, to achieve the purpose that feeding is general
That all designs is thicker, and therefore, we are designed a using this design feature of wheel hub D rings by the way of spinning crimping
Hollow wheel hub achievees the purpose that mitigate weight.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of hollow aluminium alloy wheel hub spinning casting techniques.
Technical scheme is as follows：
A kind of hollow aluminium alloy wheel hub spinning casting technique, including following technological process：Cast turning-at unsawn timber-wheel hub D rings
Spinning crimping-welding curled edges-machining-application；Turning refers to by specified requirement by wheel hub D rings at the wheel hub D rings
Place's any superfluous material parts turning simultaneously leaves crimping on the top of wheel hub D rings, forms notch, the spinning volume at wheel hub D rings at this time
While refer to being closed notch to rotary punching at crimping by spinning process, formed between crimping and hub body at this time it is hollow,
Then curled edges are welded by welding procedure again, that is, completes to wrap hollow technique, obtains wheel hub semi-finished product.
The beneficial effects of the present invention are：The present invention achievees the purpose that the hollow mitigation weight of packet by spinning flanging process,
It is 518.5 cm3 by hollow part volume, is 2.7g/ cm3 according to A356 density, is computed hollow part and saves aluminium weight
1400g realizes the lightweight of wheel hub in the case where not influencing Strength Safety, has excellent application prospect and market value.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the present invention.
Wherein：D, it represents at wheel hub D rings；1, crimping before spinning；2, hub body；3, hollow；4, crimping after spinning.
Specific implementation mode
The invention will now be described in further detail with reference to the accompanying drawings.
Refering to figure, a kind of hollow aluminium alloy wheel hub spinning casting technique, including following technological process：Cast unsawn timber-wheel
Turning-spinning crimping-welding curled edges-machining-application at hub D rings；Turning refers to being wanted by specified at the wheel hub D rings
It asks any superfluous material parts turning at wheel hub D rings and leaves crimping on the top of wheel hub D rings, formed at wheel hub D rings at this time scarce
Mouthful, the spinning crimping refers to being closed notch to rotary punching at crimping by spinning process, at this time crimping and hub body 2
Between form hollow 3, then curled edges are welded by welding procedure again, that is, complete to wrap hollow 3 technique, obtain wheel hub half at
Product.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention,
General Principle defined herein can be realized in other embodiments without departing from the spirit or scope of the present invention.
The scope of the present invention is limited by claim and its equivalent.
Claims (1)
