Description
Technical field
The present invention relates to the technical field of aluminum-alloy wheel producing and manufacturing technique, more specifically, relate to the improvement of existing aluminum-alloy wheel producing and manufacturing technique.
Background technology
The features such as aluminium alloy wheel hub is elegant in appearance with it, safety and comfort have been won more next many private car owners' favor.Now, nearly all new model has all adopted aluminium alloy wheel hub, and a lot of friend car owner also changes the wheel hub of the former upper use of sending a car into aluminium alloy wheel hub.
Aluminium alloy wheel hub advantage: one, now generally all think that the wheel hub of aluminium alloy is better than steel wheel hub, reason be nothing but following some: 1. elegant in appearance.2. light, fuel-efficient; 3. the expansion and contraction of aluminium alloy is high, good springiness; 4. heat radiation: aluminium alloy is better than the heat conductivity of steel.5. good rigidly, protects circle property good, difficult deformation, and the each several part wearing and tearing of car are just little, are applicable to running at high speed; Steel soft, easily distortion, four-wheel location is all useless, during high speed (more than 160) obviously car can shake, affect the life-span of car; 6 good springiness, improve the ride comfort in Vehicle Driving Cycle, are easier to absorb vibration and the noise in motion.
Along with the development intratype competition of aluminium alloy deep processing enterprise is more and more fierce, main engine plants are also more and more harsher to the requirement of quality product.Homogeneity competition reaches white-hot.Country is also day by day perfect to the examination of enterprise energy consumption and auditability.Traditional aluminum alloy wheel producing and manufacturing technique can not meet the demand of the factors such as environment, energy-conservation, water saving, cost, urgent need is developed the pollution of a kind of minimizing to environment, significantly reduce energy consumption, water consumption and noble metal consumption, simplification of flowsheet, enhance productivity, and the low aluminum-alloy wheel producing and manufacturing technique of cost.
Summary of the invention
The present invention is at least one defect overcoming described in above-mentioned prior art, and a kind of aluminum-alloy wheel producing and manufacturing technique is provided, and it can reduce fuel, shortens the production time, reaches energy-saving and cost-reducing effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of aluminum-alloy wheel producing and manufacturing technique, wherein, comprises the following steps:
S1. solid solution: the wheel without Vehicle Processing is framed up and carry out solid solution by T6 heat treatment requirements, in stove, temperature is 535 ℃ ± 5 ℃, and soaking time is 5 hours;
S2. quench: the product after solid solution is immersed to temperature at 10-15 in second be to carry out quench treatment in the pond of 70-90 ℃;
S3. school shape: the relative dimension of wheel rim and tympanic part is calibrated according to drawing requirement;
S4. cleaning, ball blast: to product surface clear up, Shot Blasting;
S5. clean: product is carried out to degreasing, table tune, Passivation Treatment;
S6. dry, timeliness: in temperature, be 150-230 ℃, soaking time be 35-120min to product dry, timeliness; And make product hardness reach 70-90HB.
In the present invention, in step S1, because the solid-state dissolving of aluminium alloy, diffusion are slow; It is inhomogeneous that charging mode causes product to be heated; Melting, castability are inevitably poor; For alleviating product weight, a lot of product design intensity is low.Through test, confirm, with soaking time, by 3.5 hours, extend to 5 hours, its intensity and plasticity all improve thereupon.
Further, in described step S1, while framing up, product is strung to 10 of every strings with ￠ 12 reinforcing bars, be highly no more than 1.5 meters, 60 of every frames.In described step S4, the diameter of ball blast sand is 0.5～0.8mm.
Product of the present invention can be undertaken by suspension type chain in circulation process, chain speed 1.8-2.0m/min reaches product and does not land, reduce the knock damage in circulation process, shorten 5 hours delivery dates, enhance competitiveness, oven dry, timeliness are merged to optimization, reduce fuel, reach energy-saving and cost-reducing effect.
Compared with prior art, beneficial effect is: method of the present invention is simple, can reduce fuel, shortens the production time, reaches energy-saving and cost-reducing effect.The present invention is expected to significantly promote the manufacturing technology level of bike wheel and the market competitiveness of bike wheel, shorten 5 hours delivery cycles meeting under the prerequisite of product performance, also the energy-saving and emission-reduction that bike wheel is manufactured, the significant economic and social benefit of getting will be contributed to realize simultaneously.
