Description
Technical field:
The present invention is a kind of ultrasound auxiliary electric spark deposition reparation and ultrasonic polishing integrated apparatus and method thereof, belongs to the renovation technique of ultrasound auxiliary electric spark deposition reparation and ultrasonic polishing integrated apparatus and method thereof.
Background technology:
Being used for mould repair at present has following several with the polishing method for processing:
1, surface coating technique:
Coating technology can be divided into following 3 classes by the bonding mechanism of coating layer forming process and coating layer and matrix:
1) thermal spraying: thermal spraying is that dusty spray is heated to the state that can bond mutually, and is ejected into substrate surface with certain speed, forms a tectal class technology, as flame-spraying, plasma spraying, detonation gun spraying and supersonic spray coating etc.Wherein flame-spraying, plasma spray are coated in the mould repair the most frequently used.Between repair layer that thermal spraying forms and the base material is mechanical bond, so be used for die surface modification and shape reparation under the non-shock loading condition more.
2) surface cladding technology: the surface cladding technology is the novel surface modification technology, by adding cladding material at substrate surface, and utilizes the thermal source of high-energy-density, makes the thin layer consolidation with matrix surface, form with matrix be metallurgical binding add the material cladding layer.By the thermal source that adopts in the cladding process, can be divided into flame cladding, argon arc cladding, laser melting coating.Flame cladding, argon arc cladding are used for mould repair, and be simple to operate though equipment is cheap, because heating surface area is excessive, causes thermal deformation, so repairing quality is not very high.The source for cladding energy density of laser melting and coating technique is very high, and the cladding material range of choice is increased greatly, can obtain and the high-performance of matrix metallurgical binding, multiduty cladding layer.The deflection that causes in the cladding process is very little, cladding layer surface smoothness height, but apparatus expensive, unfavorable with on-the-spot quick reparation.
2, gas phase deposition technology: vapour deposition is by physical processes such as chemistry or thermal evaporations, makes deposition materials vaporization and forms the method for solid rete at matrix surface.Vapour deposition is rapid, the more rich a kind of surface coating technology of type of development in the sufacing, it can be at the die surface deposit multilayer film of various materials, but it is applied to that many shortcomings are also arranged in the mould repair, as, with matrix be the physical mechanical combination, bond strength is not high, equipment complexity, heaviness, be unfavorable for field repair, these all limit its application scenario to a great extent.
3, electroplate: plating is the electrodeposition process that obtains metal deposition layer by electrolytic method on the surface of solids.It can obtain multiple coating, by disposing different plating baths, use a set of equipment can plate multiple metal, the complexity but equipment is compared with the equipment of other processing technologys, and in the process of electroplating, produce with serious pollution electrolyte, environmental pollution is more serious, the quality of comparing coating with thermal spraying is so not outstanding, can produce pernicious gas, flue dust, harmful radiation light, do not form alloy with matrix surface, the accessory size that need repair is subjected to the restriction of electroplating bath, and some big parts can't be electroplated.
4, electric spark deposition reparation: electric spark deposition technology (electro sp40rk deposition) is to utilize short pulse duration, the high-frequency pulse power that electrode material (anode) is welded to a kind of pulsed arc microwelding technology on the metallic matrix.The major advantage of electric spark deposition technology (ESD) is electrode material to be combined enough low heat inputs with matrix alloyization.It has reduced the thermal deformation of matrix material tissue, thermal stress; Simultaneously because coating is a metallurgical binding with matrix, therefore carries out surface-treated workpiece and low-heat such as plasma spraying, electrochemistry plating and import coating process and compare its surface and have better mechanical performance through ESD.Compare with above other several renovation techniques, though electric spark deposition has above advantage, but it also has its bottleneck that can't break through all the time---be difficult to obtain to surpass the dense coating of 350 μ m thickness, this problem has limited electric spark deposition The Application of Technology occasion greatly.
5, ultrasonic polishing: ultrasonic polishing is that the ultrasonic vibrational energy that the ultrasonic vibration system with suitable power output produces is attached on the die surface that will repair, thereby make polishing tool and die surface carry out ultrasonic high-frequency mechanical vibration friction, be reached for the surface finishing processing method of mold polish with certain frequency and certain amplitude.This method has been widely used in the processing of die surface polishing, has not only saved the polishing time after the mould repair greatly, and has reduced the cost of mould repair to a great extent.
