Description
Technical field
The present invention relates to the brush coating technology, specifically be meant the especially brush plating lathe of connecting rod of inner bore parts.This lathe at be the part of endoporus class, it both had been applicable to the reinforcement to new product spare, was applicable to the reparation of abrasion piece again and made.
Background technology
The brush plating is a kind of surface processing technique, and it is to utilize electrochemical method that metal ion is reduced to metal, and is deposited on the surface of metal or on-metallic article, forms the metal cladding of satisfactory level and smooth densification.Along with science and technology and the development of producing, the field that the brush coating technology relates to is more and more wider, and people are also more and more higher to the requirement of coating.At present, the application of metal plating has spreaded all over each production and the research department of economic activity, has great significance in production practice.
But along with China's rapid growth of economy, the energy and problem of resource are more and more outstanding, and the exploitation of a lot of resources has entered mid-term or late period, and the expert estimates that to the year two thousand twenty, China will have a strong impact on development because of the scarcity of the resource and the energy.For this reason, Chinese Academy of Engineering Xu Bin scholar academician vigorously advocates Green Remanufacture Project in China, provides a most effectual way for addressing this problem.The technology of wherein a lot of tradition and new research and development has been listed in the gordian technique of re-manufacturing technology, as hot-spraying techniques, laser technology, plasma technology, brush coating technology etc.But the brush coating technology also mainly rests on the manual brush plating stage in concrete the application, exist labor strength big, and brush plating efficient is low, shortcomings such as quality of coating instability.In addition, the anode of plating pen generally adopts graphite during brush plating, the outside is wrapped up in water-absorbing material (as cotton, artificial wool, polyester-cotton blend cover etc.), this plating pen is simple in structure, flexible during use, relatively be fit to scattered different brush plating of feature, but also have tangible problem in using, the one, lapping is not wear-resistant, and every brush plating just needed parcel again in 20～30 minutes; Another problem is that the plating pen can't replenish metal ion in plating bath, in order to save plating bath, generally all as much as possible the plating bath that gutters down is reclaimed during brush plating and utilization once more, but carrying out along with the brush plating process, concentration of metal ions in the plating bath reduces gradually, and sedimentation velocity and quality of coating also descend gradually, when concentration of metal ions be lower than original liquid concentration 40% the time, plating bath just has to scrap, and the plating bath of scrapping needs strict emission treatment.Certainly and since brush plating in the past at part generally all be the part of a little scattered or short runs, these problems also are not very outstanding.
Making is the industrialization of maintenance again, and it with a difference of the maintenance of general meaning is, maintenance to as if scattered part to be repaiied, its quantity may be one or several, and the situation between each part has nothing in common with each other seldom, vary, can't formulate unified technological specification.And make again to as if the part to be repaiied of standard in batches, pre-treatment and preprocessing have been carried out in their unifications before making again, therefore it is identical to wait to repair the position, it is consistent to wait to repair requirement, can formulate unified technological specification and carry out the manufacturing again of mass, can build the streamline of making again at a certain part as production.Under this background, the automatic technology of brush plating progressively is developed.
Interior hole type parts (as the connecting rod of engine, cylinder body etc.) is one of most important part type, and it and cylindrical class part (as axle, bearing, wear ring etc.) are formed kinematic pair jointly, realize the relative movement and the transmission of power of part.The inefficacy of interior hole type parts causes satisfying dimensional requirement based on wearing and tearing and distortion, therefore, mainly is to recover its coordinating size and surface property to the reparation of such part.In actual use, generally adopt old-fashioned plating pen to carry out brush plating, old-fashioned plating pen generally adopts graphite anode (Special Circumstances also have the stainless steel of employing as anode), and wraps absorbent cotton and polyester-cotton blend cover outside.It is method very commonly used in the prior art that artificial hand-held old-fashioned plating pen carries out brush plating and since brush plating to as if the part of mass, this method exposes following problems.
The one, brush plating efficient is low.Artificial brush plating can only one of brush plating be plated pen at every turn, and the requirement of workpiece reparation industry is not satisfied in brush plating in batch.
The 2nd, brush plating standard disunity.Because brush plating is manual operation, randomness is strong, and to workman's technical requirements height, the workpiece qualification rate of brush plating also can be affected.
The 3rd, the plating bath waste is serious.Prolongation along with the brush plating time, concentration of metal ions in the plating bath descends, but when concentration of metal ions drops to 40% left and right sides of original content, just can't continue to obtain qualified coating, plating bath just has to scrap in this case, and also have about 40% not utilization of metal (generally being nickel) this moment in the plating bath, cause very big waste.
The 4th, need repeatedly change the plating pen.The technique of brush plating process comprises multistep operations such as clean, the strong activation of electricity, weak activation, prime coat and plating working lining, owing to can not obscure mutually between the plating bath, and the raffinate in the plating lapping is difficult to remove totally, therefore per step operation all needs to change the plating pen in the brush plating process, realizes that the automatization brush plating is extremely inconvenient.
The 5th, parts fixation accuracy requirement height.Because the cotton elasticity in the jacket is very little, therefore necessarily require to plate between pen and the workpiece very high quality of fit is arranged, otherwise will cause pressure distribution inequality between plating pen and the workpiece, the local current density that pressure is big is big, and the coating deposition is fast, otherwise, the part current density that pressure is little is little, and sedimentation velocity is slow, and last result is a brush plating off-centre, and the big part of pressure is owing to sedimentation velocity causes the coating part too thick soon, and very coarse.When post-production, when being ground to when requiring size, the zone that coating is thin almost is ground to matrix, and the coarse particles in thick zone does not also grind off, and therefore becomes waste product.With regard to the connecting rod part that this project is selected, because the irregularity of its size, the clamping precision problem almost is insurmountable, therefore must start with from the angle of technology, reduces the requirement to clamping precision.
The 6th, the brush plating temperature is too high.The brushing plating voltage that requires at the brush plating plating bath carries out brush plating, and its current density range is 1-2A/cm
2, when carrying out the inner hole part brush plating,, carrying out brush plating as requested voltage because plating pen is bigger with the part contact area, its electric current will reach kiloampere even thousands of amperes, will produce a large amount of heat energy.Simultaneously again since during the plating of this kind plating brush in the part plating bath amount of institute's splendid attire seldom, the plating bath circulation is not smooth, so the heat that brush plating produces can't in time discharge and cool off, causes temperature to raise rapidly, the coating of burning.
The 7th, cost is higher.Plating pen is a running stores, and the replacing because size is just had to inadequately after for some time is used in anode loss gradually in the brush plating process, and the employed high purity graphite price of anode is more expensive, and therefore the replacement cost of plating pen is very high.
The contriver develops a kind of specially at the plating pen of brush plating usefulness in the early stages, and its concrete structure is a handle, handwriting and insulation crossbeam; This handle comprises a handle main body, suspension part and clamping part, and this suspension part connects a handle main body top, and this clamping part connects a handle main body below; This clamping part lower end clamping one anode; This handwriting is made up of at least two plate bodys and bristle, and this bristle is located on this plate body outer surface, parallel this anode both sides of being located at of this at least two plate body, and this at least two plate bodys upper end is connected with this handle main body; This at least two plate bodys lower end all is located on this insulation crossbeam with the anode bottom and is not contacted mutually.This plating pen not only can effectively be saved plating bath, and long service life, makes the brush plating cost significantly reduce.But the improvement of plating pen can not effectively solve the problem of brush plating efficient, and therefore based on this problem, the contriver has also proposed a kind of electric brushing coating installation, and this device has a motor can drive the rotation of plating pen, with the brush plating that realizes semi-automation.The more artificial brush plating efficient of this device obviously improves.
But through studying for a long period of time, the contriver finds that still there are a lot of problems in said apparatus, in conjunction with bad, makes the brush plating poor effect as the to-and-fro movement of the rotation of plating pen and base.In addition, need repeatedly to change the liquid flushing in the brush plating process, because the motion of base makes these programs must realize under the environment that leaves standstill that efficient is further limited.The motion of base also causes the plating bath spilling easily, is connected poorly sealed problem such as loosening with connecting rod.
In sum, can't satisfy the requirement of endoporus automatization brush plating, even can't guarantee to obtain qualified product, therefore need make improvements and improve by traditional way.
