In the planetary type portable impact device, the structure is simple, the energy consumption is low, the operation is simple, the labor intensity is low, the residual stress in welding can be obviously eliminated, and the comprehensive service performance of the welding structure is improved.
Description
Technical field
The utility model belongs to the welding equipment class, relates in particular to a kind of planetary portable shock treatment device that is used to eliminate welding residual stress.
Background technology
Welding vestige stress is one of reason that takes place in the metal weldedstructure military service process fatigue failure, and the alternate stress that outside alternate load produces and the superposition of welding residual stress will speed up the germinating and the expansion of welding point zone crackle.A large amount of theory analysises and experimental study all show welded fatigue crack generally in the welding toe germinating, and to internal extended.It is thus clear that peculiar welding vestige stress of welding point and geometry sudden change are two principal elements that influence fatigue performance of welded structure.If can change how much sudden changes of welding residual stress field and welding point, will improve welded fatigue behaviour effectively.At present; Eliminate welding residual stress on the engineering and the laboratory and mainly be based on welding region generation deformation elongation; Like the deformation of creep and plastic deformation etc., its process mainly comprises: post weld heat treatment, mechanical grinding toe of weld method, shot-peening, overload, hammering, roll, local heat, TIG moltenly amend the law, ultrasonic impact etc.Said method can be eliminated the part welding residual stress; But the characteristic that is limited to process itself; In the practical engineering application process, demonstrate certain deficiency, need complicated heating, heat-preserving equipment like the post weld heat treatment method, energy consumption is big; For the structure that adopts made such as quenched and tempered steel, stainless steel, composite plate, annealing is eliminated welding residual stress and is had technical difficulty; The molten construction technology complicacy that amends the law of TIG, inappropriate technology is prone to cause side effect; The shot-peening method exists that noise is big, equipment is huge, and once investment is big, energy consumption is high, can not make things convenient for deficiency such as mobile operating.Therefore need a kind of light and handy, portable equipment of exploitation be used for after welding treatment and eliminate welding residual stress, this equipment need possess efficient height, characteristic that energy consumption is low simultaneously, to satisfy the manufacturing demand of development low-carbon (LC).
The utility model content
The purpose of the utility model provides a kind of planetary portable percussion mechanism that is used to eliminate welding residual stress, possesses efficient height, characteristic that energy consumption is low in process of production.The utility model thes contents are as follows:
A kind of planetary portable percussion mechanism that is used to eliminate welding residual stress comprises planet beater wheel, transmission mechanism, motor, shell and handle;
Said planet beater wheel is installed on the planetary plate, and the speed regulator of regulating said planetary plate rotary speed is installed on the said shell, and said motor is connected with power supply through cable.
Said planet beater wheel has 2～8.
The rotation of said motor passes to said planetary plate through said transmission mechanism in the time of in working order, and said planetary plate rotates at a high speed and drives said planet beater wheel percussion weld and weld seam near zone.
Said planet beater wheel only produces rolling friction in the course of the work.
Said motor rotates the said planetary plate of driving at a high speed and rotates.
Said handle has a plurality of, and the shape of each handle is identical or different.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Symbol description
1 handle I; 2 shells; 3 motor; 4 transmission mechanisms; 5 planet beater wheels;
6 planetary plates; 7 bolts; 8 handle II; 9 speed regulators; 10 cables.
The specific embodiment
Below, further specify the utility model with embodiment, but the protection domain of the utility model is not limited in embodiment.The variation and the modification of other that those skilled in the art is made under the situation of spirit that does not deviate from the utility model and protection domain still are included within the utility model protection domain.
Embodiment 1
Be further described according to 1 pair of this utility unit of accompanying drawing below.
In Fig. 1, shell 2 is cylindrical, and motor 3, speed regulator 9, transmission mechanism 4 are equipped with in its inside.Rotate after motor 3 energized, transmission mechanism 4 passes to planetary plate 6 with high speed rotating, makes planetary plate 6 produce the high speed rotating of 10000～20000rpm, and drives four planet beater wheel 5 high speed rotating.Planet beater wheel 5 can be 2～8.Bolt 7 is fixed on planet beater wheel 5 on the planetary plate 6.Difform handle I 1 and handle II 8 (their shape also can be identical) are installed on the shell 2, are used to control, mobile device, and in processing procedure imposed load.Draw the cable 10 of sufficient length on the shell 2, connect external power source, supply with motor 3 needed electric energy.
The utility model is connected power line the single phase poaer supply of 220v earlier, starting switch in real work; Motor is started working, and produces high speed rotary motion, passes to planetary plate through transmission mechanism; Planetary plate produces the high-speed motion of rotating speed at 10000～20000rpm, and under the drive of planetary plate, the detour rotation of astrolabe of planet beater wheel is made the high speed revolution motion, planet beater wheel high speed impact welding point surface; The planet beater wheel can freely rotate in the process of impacting; Be that planet beater wheel revolution time also can rotation, in the process of impacting the welding joint surface, only produce rolling friction, specimen surface produces the plastic deformation layer.Experimental result shows; The welding vestige stress harmful that the welding point zone exists to the structural fatigue performance; After planetary portable percussion mechanism processing; Change the compression that helps fatigue performance of welded structure and military service performance into, its numerical value can meet or exceed the yield limit of original material.
