Description
Technical field
The utility model relates to the automotive hub processing unit (plant), relates in particular to a kind of device of automotive hub abrasive Flow flash removed.
Background technology
The first half of the year in 2010, the auto output of China was 847.22 ten thousand, and the terminal sale amount is 718.53 ten thousand, was sure to occupy first in the whole world, estimated the whole year in 2010 and reached 1,500 ten thousand.Along with spreading of Global finance storm, it is the most serious to be in the impact that the import and export industry of the teeth of the storm receives, and especially the influence that receives of traditional labor-intensive enterprises such as automobile manufacture industry is more serious.National governments are strict day by day to energy-saving and environmental protection and safe requirement in the economic crisis, become best selection so adopt aluminium alloy to produce wheel hub in a large number.Aluminium alloy wheel hub of vehicle is attractive in appearance, energy-conservation with it, thermal diffusivity is good, light weight, corrosion-resistant, processability is good etc., and characteristic progressively replaces the steel wheel hub.External aluminium alloy wheel hub manufacturing industry obtained to grow up fast in the seventies in 20th century.Like the aluminium alloy wheel hub of North America Light-duty Vehicle, only accounted for 19% in 1987, accounted for 58.5% to calendar year 2001; Japan's car entrucking rate crosses over 45%; Europe crosses over 50%, almost covers various vehicles to 2010 aluminium alloy wheel hubs, just progressively instead of steel ratch hub.At present in automobile, tens kinds of key components and parts of motorcycle, aluminium alloy wheel hub is uniquely can substitute import, but also can be to the important spare part of developed countries such as the U.S., Japan and Europe outlet.Along with the quickening of the globalization of auto industry market, buying internationalization process, China becomes manufacturing industry base, the world day by day.This is a golden opportunity, but is new challenge.At present the general layout in Chinese automobile market is an international capital with 40% capital; Occupy 50% the market share; Seize 70% profit; Along with the price war of vehicle complete vehicle imputes to parts, therefore almost each auto parts and components enterprise all is faced with a problem that promotes core competitiveness, and grasping and using advanced manufacturing technology is a most important ring that promotes core competitiveness.More steadily safe, more energy-conservation for responsive motor, reduce the harsher requirement of noise, pollutant emission, aluminium alloy wheel hub develops to lightweight, wide wheel rim, high strength, target direction such as more attractive in appearance.So wheel hub carries out flash removed processing before dispatching from the factory and surface treatment is very necessary, to satisfy attractive and durable requirement.
The quality of wheel hub is one of main symbol of weighing vehicle complete vehicle quality and class.Wheel hub is positioned as A level security spare.Wheel hub is one of important spare part in the automobile running system, is bearing the various stress that produce in vertical load, cross force, driving torque and the driving process of vehicle.It is the part of high speed rotary motion, requires that dimensional accuracy is high, degree of unbalancedness is little, and the wheel rim profile of support tire is accurate, and light weight also has certain rigidity, elasticity and wearability.Automobile is round-the-clock product; Need be under various outdoor climatic environments reliability service; And guarantee its durability, and wheel hub directly contacts with ground, not only receives outdoor climatic influences; The mud, sand, rubble that also need stand ground impacts and the influence of the sputter of water, is to stand the worst parts of environmental condition in the automobile.Because it is concerning one of critical component of car load safety wheel hub, improves wheel hub reliability of operation and durability so flash removed processing, surface treatment and application need be carried out in the aluminium alloy wheel hub surface, secondly be to improve its decorative appearance.High-grade automobile is especially high to quality and the outward appearance of wheel hub, therefore, improves and guarantees that the surface quality of wheel hub also is the important step of raising competitiveness in international market.
At present, after the processing on domestic aluminium alloy wheel hub surface adopts artificial polishing and mechanic shot peening and ball blast etc. to handle basically, comprise the method for oil removing, pickling and phosphatization etc. again through Chemical Pretreatment, realize the final surface that obtains cleaning and have certain fineness.The common problem that these traditional diamond-making techniques exist is: (1) is bigger to workman's specification requirement height and labour intensity, and working environment is very abominable; (2) technology stability and homogeneity of product are poor; (3) environmental pollution is serious; (4) production efficiency is low.Therefore, exploitation aluminium alloy wheel hub high-efficiency cleaning precision processing technology and equipment are particularly urgent.
Two, domestic and international present Research and development trend
At present, complex-curved flash removed and polishing processing method commonly used have: methods such as manual polishing, emery wheel polishing, electrochemical polish, the auxiliary polishing of ultrasonic wave, magnetic force polishing and abrasive Flow polishing.But conventional Machining of Curved Surface mode is difficult to be adapted to the processing of special-shaped curved flash removed and polishing owing to receive the restriction of shape and efficient, can not satisfy the requirement of precision and efficient, and its reason is following:
(1) flexible polishing mode such as magnetic grinding and electric current change need be by means of instrument such as pole form; The distribution of the magnetic line of force; The straight line processing characteristics of arrangement of electrodes and contactless water jet machining, to special-shaped curved irregular holes inner surface curved surface, groove etc. can't carry out efficiently, Precision Machining.These processing modes are mainly used in the processing of axial symmetry replicated optics element, not too are fit to special-shaped curved removal burr and precise finishing processing such as wheel hub.
(2) processing of abrasive Flow is used kinematic viscosity than higher mixing abrasive Flow in order to improve working (machining) efficiency, and is hoped that abrasive Flow has low rheology rate, morphotropism is good, and is difficult for bonding.Utilize hydraulic cylinder to carry out powerful extrusion process, can destroy special-shaped curved surface accuracy during complex surfaces such as the slit of narrow and small complicacy, groove because full-bodied abrasive Flow is flowed through, when processing be thin-walled parts the time, even can destroy part.The motion mode of extrusion honing is the reciprocating of rule in addition, and the texture that the outer surface after the processing has rule is difficult to reach high-precision finished surface.Its main application is the inner surface of pipeline flash removed, can not adapt to special-shaped curved high accuracy polishing requirements fully.
(3) people such as Mamilla Ravi Shankar is similar to the screw rod excitation abrasive Flow of drill bit or the mode through workpiece motion s through use; The motion path that changes abrasive particle makes the motion of abrasive particle have randomness; Eliminate tangible directionality cutter trade; And generation is more and the touch opportunity of processed curved surface, makes abrasive Flow further mix, and improves polishing efficiency and surface roughness.But in the spiral processing method; The required energy of abrasive particle elaboration is to be delivered to abrasive Flow again to workpiece and produce fine shear action by screw rod; The energy-producing violent loss of this process meeting; Reduce working (machining) efficiency, can not satisfy efficient modern manufacturing industry requirement, and processing uniformity awaits further improvement.
(4) also all there are certain defective in Electrolyzed Processing, grinding, polishing etc.Though like the direct contact workpiece surface of the electrode in the Electrolyzed Processing, need make electrode and workpiece to be machined keep certain clearance, so receive shape limits during Electrolyzed Processing, and the polishing that is not suitable for complicated special-shaped curved and special-shaped hole inner surface is processed.Aspect free form surface automation flash removed process technology, people such as professor Zhao Ji of Jilin University have proposed inclination angle type ultrasonic polishing method, realize the automation polishing of mold freedom curved surface through Robotics.People such as professor Zhang Lei have studied small tool robot polishing free form surface technology.The Gao Bo of Harbin Institute of Technology, Yao Yingxue, thank to professors such as outline, Yuan Zhejun and propose the air bag polishing technology is applied to optical instrument part curved surface, obtained good effect.The timing ring professor of Zhejiang Polytechnical University waits the people that air bag polishing technology and Robotics application in conjunction are polished in the grinding tool free form surface, has obtained Ra 0.005 μ m rough surface.But these process technologies all adapt to complicated abnormal shape curved surface flash removed processing such as automotive hub well than difficulty.
