Description
Technical field
The present invention relates to a kind of reparation machine.
Background technology
Metal surface enhanced prosthetic appliance is the new product of developing in recent years both at home and abroad, is mainly used in repairing the wearing and tearing of defect, die surface of surface of workpiece and overproof etc.It has in process, can not produce thermal stress, indeformable, without the advantage such as heat-treating, be a comparatively ideal metal surface prosthetic appliance.
At present, for the R&D and production of this series products, the technology of Japan, the U.S. is leading, the introduce technology development or produce this kind equipment of domestic Ye You part producing producer.This kind equipment that can buy on domestic market is mostly external import and the production of introducing technology, and domestic production producer is relatively poor by the technical performance of this kind of equipment of own technology development.
Domestic and international most of like product, all adopts Industrial Frequency Transformer isolation, silicon-controlled voltage regulation, and resistance and inductance are to capacitor charging, and controllable silicon completes the realization of burst pulse, large electric current to capacitor discharge.Owing to adopting Industrial Frequency Transformer, the volume and weight of equipment is increased greatly; Adopt resistance and inductance to capacitor charging, the operating efficiency of equipment is obviously reduced (general work efficiency <50%); Adopt controllable silicon to capacitor discharge, make the shutoff of its output pulse current unreliable, in work, produce sometimes arc-welding effect.
For the problems referred to above, the present invention proposes the key measures of multinomial improvement, develop on this basis efficient metal surface peening and repaired machine.The equipment that the present invention develops relatively has the features such as operating rate is fast, operating efficiency is high, reliable working performance, volume is little, lightweight, the life-span is long with domestic and international similar product.
Summary of the invention
The technical solution adopted in the present invention is: machine is repaired in a kind of efficient metal surface peening, comprises equipment control case, rotary welding gun and external wire folder composition; Described equipment control case is mainly used in installing Switching Power Supply, electric capacity, double-thyristor, isolating transformer, rectifier, power switch, scram button, digital display screen, frequency adjustment controller and adjusting knob; On described rotary welding gun, be useful on the argon gas shower nozzle of protection metal surface quality.Groundwork principle of the present invention is: utilize its inner rectification, pressure regulation and high-frequency inversion technology produce the burst pulse of isolating with input power, and (1 μ s～50 μ s), large electric current (hundreds of A～several thousand A), form current loop by the metal electrode on rotary welding gun (welding rod) and surface of workpiece, thereby produce spark discharge between surface of workpiece and electrode, make it form transient state high energy, at contact area by electrode transient heating to 8000～25000 ℃, make metal electrode material surfacing to the metal works rejected region surface being repaired, form good metallurgical binding.Because the whole course of work is burst pulse, large electric current, can not produce arc-welding effect, the workpiece being repaired can not produce overheated and distortion.Utilize each adjusting knob on equipment can adjust easily the frequency (50～1500Hz) of pulse current, the peak value (100A～1500A) of pulse current, reach by adjusting output voltage the object of adjusting pulse current peak), thus the speed of capable of regulating repair and desired quality.
The present invention adopts high-frequency inversion technology, can effectively reduce the volume and weight of isolating transformer; Adopt two IGCT symmetrical operation patterns to replace the single-ended mode of operation of IGCT, make it under any working condition, can not produce arc-welding effect, improve equipment functional reliability; Owing to having replaced capacitance-resistance charging modes, the operating efficiency of equipment is effectively improved (general work efficiency >85%, and most of like product operating efficiency is only 45% left and right); The appropriate design of control and inverter circuit, makes equipment work more safe and reliable.Thereby compared with similar products, this equipment is under the condition of the same power of output, and its volume and weight obviously reduces, and has improved greatly again its operating efficiency and reliability simultaneously, reducing under the condition of electric power, operating efficiency and operating rate can improve 2～3 times; Equipment is provided with kinds of protect control circuit, and assurance equipment is worked reliably and with long-term, extension device service life.
Described equipment input power: 220V ± 15%, 50Hz; Maximum Power Output: 2KW; Pulse current frequency: 50Hz-1500Hz is adjustable continuously; Welding gun rotating speed: 50r/min-1000r/min is adjustable continuously.
The present invention is mainly used in: the repair and intensify of all kinds of metal parts; The repair and intensifies such as overproof, the wearing and tearing of all kinds of moulds; The reparation such as defect, trachoma of hot investment casting; Aero-engine titanium alloy and high temperature alloy carburizing etc.
The technical advantage that the present invention will realize is: REPAIR WELDING process is good metallurgical binding, and weld layer and workpiece adhesion are strong; Workpiece to be machined input low in calories, can not produce thermal burn, indeformable, without thermal stress change, without heat-treating; Welding process has argon shield, makes it non-oxidation layer, and sedimentary deposit can be controlled according to workpiece instructions for use thickness; Welding material can be selected according to the requirement of workpiece to be machined, and range of choice is more extensive; Have superior weldering property again, weld layer can carry out machining simultaneously; Equipment simple to operate, running cost is low, has wide range of applications.
