Abstract
The utility model belongs to the welding equipment category, it is formed through cable junction by ultrasonic power generator and the portable vibration processing rifle of taking piezoelectricity ceramic transducer, amplitude transformer, multi-needle working head. The portable vibration processing gun converts an ultrasonic electric signal of the ultrasonic power generator into mechanical vibration with ultrasonic frequency, and acts on a welding area through the vibrating needle. The air cooling structure is very convenient to use, the labor intensity is low, and cooling liquid such as water and the like is not needed in use, so that the welding residual stress can be obviously eliminated, the bearing capacity of the welding structure is improved, and the fatigue life of the welding structure is prolonged.
Description
Affiliated technical field
The utility model belongs to the welding equipment class, relates in particular to a kind of portable vibration treating apparatus that is used to eliminate welding residual stress.
Background technology
Fatigue fracture is the principal mode that metal structure lost efficacy, and wherein welded fatigue failure performance is more outstanding.Welding residual stress is the one of the main reasons of fatigue failure, and the double action of external load and internal residual stress will cause the generation of weld metal zone and nearly seam district crackle.Big quantity research and practice show that the general crack initiation of fatigue rupture of welding point is the transition position of mother metal and weld seam in the toe of weld position of welding point, can improve welded fatigue strength effectively if can improve the fatigue crack crack initiation performance of welding point transition region.Common after welding treatment, as heat treatment, mechanical grinding toe of weld method, shot-peening method, overload method, hammering method, local rolled-on method, point-like heating and TIG molten amend the law, ultrasonic vibration method etc., be to solve welding residual stress problem method preferably.But this problem complexity that becomes when handling the Welding Structure of large-scale, heavy wall, conventional after welding treatment method all has certain difficulty, even becomes impossible.
Summary of the invention:
The purpose of this utility model provides a kind of portable vibration treating apparatus that is used to eliminate welding residual stress, to solve an above-mentioned difficult problem.
The purpose of this utility model realizes like this:
A kind of portable vibration treating apparatus that is used to eliminate welding residual stress is handled rifle by the portable vibration of ultrasonic power generator and band piezoelectric ceramic transducer, luffing bar, spininess working head and is formed by connecting through cable.
Supersonic generator is provided with the inlet wire seat of single phase poaer supply and the output line seat of ultrasonic power, also is provided with knob and the vernier knob of regulating size of current on the supersonic generator panel, and the test button, and is provided with overload-alarm lamp and buzzer.
The utility model links to each other by power line single phase poaer supply with ultrasonic power generator in being arranged on casing, frequency, power conversion through the ultrasonic power generator, handling rifle by the cable of high pressure resistant voltage with portable vibration links to each other, portable vibration is handled rifle and is changed the ultrasonic signal of telecommunication of ultrasonic power generator the mechanical oscillation of supersonic frequency into, acts on the zone of welding by immersion needle.
Because the utility model has adopted above technical scheme, on the military equipment of certain model, directly use product of the present utility model that welding point is eliminated welding residual stress and handle.Result shows, there is welding vestige stress without the welding point of vibration processing near yield strength, and the residual stress of treated welding point changes the compression that helps fatigue performance of welded structure into by tension, and its numerical value can reach the yield limit of compression.This device is because volume is little, in light weight, so very convenient in use, labour intensity is little.And owing to adopt air-cooled structure, so in use do not need cooling liquid such as water.And the portable vibration treating apparatus in use, can eliminate welding residual stress significantly, improves welded bearing capacity and fatigue life, thereby obtained good economic and social benefit.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is explained as follows:
In Fig. 1, the shell of supersonic generator 1 can be designed to horizontal or vertical, in the laboratory or fixedly station use available the former, the available latter who under situation of movement, uses.On horizontal cabinet, wheel is housed, handle is housed on vertical cabinet is convenient to move.Two junction blocks are arranged in the back of cabinet, and one is that the inlet wire seat of single phase poaer supply links to each other with power line 2, and one is that the output line seat of ultrasonic power links to each other with output cable 9.Output cable can not adopt common electric wire, must adopt high voltage bearing power source special line.An ammeter is arranged, the situation of change that can observe output current at any time in the front of cabinet.For electric current that makes output and the optimum Match of vibrating on the rifle arrival acoustics, also be provided with knob and the vernier knob of regulating size of current in front on the plate, and the test button.And this equipment of use for safety also is provided with overload-alarm lamp and buzzer.
In Fig. 1, vibration rifle 3 is made up of shell, piezoelectric ceramic transducer, luffing bar 4, spininess working head 6, handle 7, switch 8, and rifle body front casing 5 front ends are the column type muzzle, through the spininess working head 6 that is threaded.Switch 8 is equipped with in the appropriate location of handle 7 behind the rifle body, directly controls when being convenient to operate.
The utility model is in real work, after power line 2 is connected the single phase poaer supply of 220V, supersonic generator 1 is started working, after piezoelectric ceramic transducer receives the signal of telecommunication of supersonic generator 1, generation 20～30KHZ, output amplitude are 3～5 microns vibration, after luffing bar 4 amplifies, produce 30～60 microns ultrasonic vibration, transfer vibrations on the workpiece by spininess working head 6, workpiece is carried out ultrasonic vibration handle.Experimental result shows, there is welding vestige stress without the welding point of vibration processing near the welding point yield strength, and the residual stress of treated welding point changes the compression that helps fatigue performance of welded structure into by tension, and its numerical value can reach the compression yield limit of material.
