Abstract
The invention discloses a hub production method. The hub production method includes following steps: 1), melting: preferably using an oil-burning or gas-burning tower-type quick melting furnace, and also using an aluminum chip melting chamber; 2), refining: using fixed refining equipment for refining to obtain a deoxidized and desulfurized steel ladle; 4), casting at low temperature: adopting a low-pressure casting process for production, wherein a die is mainly in a form of a four-section die, and the die is cooled by both water and air; 5), using X rays to detect defects; 6), thermally treating; 7), machining; 8), checking airtightness: a method of checking airtightness of an aluminum hub is realized through a hydrostatic test which refers to maintaining pressure for 30 s under air pressure >/=0.4 Mpa and checking air leakage condition of the aluminum hub by observing air bubbles in water when the aluminum hub leaks air; 9), coating. coating thickness and spraying quality of manual spraying are difficult to control, and accuracy of the coating thickness can be controlled within 10 mm through automatic spraying which is uniform.
Description
Technical field
The present invention relates to a kind of wheel hub production method.
Background technology
At present, although the low-pressure casting process equipment investment of wheel hub is slightly higher compared with traditional gravity casting machine, but force of gravity is cast with more preferable crystallization and freezing effect, and because being improved the effect of hydrogen dissolubility in the alloy under pressure field, and can relatively reduce the effect that pin hole produces, therefore received use widely by most automaker.While it is true, low pressure casting is in wheel hub produces, still there are some problems being difficult to break away from technology
；The most traditional aluminium alloy wheel hub electroplating technology oneself can not meet the demand of the factors such as environment, energy-conservation, water saving, cost, it is badly in need of developing a kind of minimizing pollution to environment, significantly reduce energy consumption, water consumption and precious metal consumption, simplification of flowsheet, improve production efficiency, and the wheel hub film plating process of low cost.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of wheel hub production method, and this production method technique is simple, eliminates a lot of repeatability operation, improves work efficiency.
For achieving the above object, the invention provides a kind of wheel hub production method, comprise the steps, 1) fusing: select the tower quick melting furnace of fuel oil or combustion gas to be preferred during thawing, be equipped with aluminum bits melting chamber simultaneously and use；
2) refine: use fixed refining equipment refine, obtain the ladle of deoxidization desulfuration；4) low pressure casting: use low-pressure casting process to produce, mould is based on the form of four die sinkings, and mould cooling is hydropneumatic；5) x-ray inspection；6) heat treatment: the Technology for Heating Processing of aluminium wheels is the solid molten Ageing Treatment (T6 process) that adds, technological requirement temperature uniformity≤± 5 DEG C；7) machining: with import or domestic single-shaft vertical or horizontal digital-control lathe, High Precision CNC machining cell, processing sequence is subdrilling rear car, positions with product bolt hole, turning rotating speed at least 2500r/min；8) air tight test: the method for aluminium wheels air tight test has the water pressure test, the water pressure test to be pressurize 30s under the air pressure of >=0.4MPa, checks the gas leakage situation of aluminium wheels by bubble during aluminium wheels gas leakage in visual observations water；9) application: improve corrosion resistance and the aesthetic feeling of aluminium wheels, in order to ensure the quality of application, production scene requires that cleaning is dustless.Coating layer thickness and the coating quality of manual spray are wayward, and automatically spraying can by the precision controlling of coating layer thickness at 10mm and uniformly.
The invention has the beneficial effects as follows: the present invention improves working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
