Description
Technical field
The present invention relates to a kind of running gears that elimination welding residual stress machine is impacted for automatic ultrasonic, belong to welding neck
Domain.
Background technique
After using the welding of various welding welding methods, weld seam is easy to produce biggish welding remnants and answers metal material
Power especially can generate biggish tensile stress in face of weld, if technological means is not taken to eliminate or reduce this portion of residual
Stress is easy to produce face crack when weld seam is on active service or even is broken, especially high-strength steel, high-carbon steel or big slab,
The seam of complicated welding point is easiest to that the crackle due to caused by face of weld residual stress or fracture occurs.Traditional elimination weldering
The method for connecing residual stress is in the case where permission using stress relief annealing, largely or can completely eliminate weld seam
Residual stress, but the method that not every welding structure can take stress relief annealing in actual production.
Ultrasonic bonding stress elimination equipment method is external more popular after welding treatment method, ultrasonic bonding stress elimination
The basic principle of equipment is exactly to push percussion tool to impact metal with 20,000 times per second or more frequencies using high-power ultrasonics
Body surface is made metal surface generate biggish compression plasticity and is become due to the high frequency of ultrasonic wave, the big energy efficiently and under focusing
Shape；Ultrasonic bonding stress elimination equipment wave changes original stress field simultaneously, generates the compression of certain numerical value；And make by
Impact site is strengthened, surface local strengthening and the method for eliminating residual stress.This method is first in the Ukraine of the former Soviet Union
Prolong life, rapidly developed in nineteen sixties in the U.S., it is recognized that be that raising fatigue performance of welded structure is most effective
Method, and promoted and applied rapidly in developed country, ultrasonic bonding stress elimination apparatus is set as after welding treatment
Standby, it can improve the Multiple factors for influencing weldquality simultaneously, such as stress, defect, toe of weld geometry, surface peening be several
Aspect, so have the effect got twice the result with half the effort to the fatigue behaviour for improving welding point, the fatigue for the welding point that can make that treated
Intensity improve 50%-120%, 5-100 times of fatigue life.After using the processing of ultrasonic bonding stress elimination equipment,
Traditional polishing and the process that removes slag are eliminated, working time 20% has been saved, has reduced labor intensity, improved production efficiency.
Meanwhile this method is also widely used in following three aspects: (1) intensive treatment is carried out to metal parts surface, to improve zero
The surface quality of part and fatigue life；(2) stress field is adjusted, welding deformation is reduced, guarantees the dimensional stability of workpiece；(3) right
The processing that position eliminate welding stress is repaired in machine components local welding.Present this method is in external mechanical manufacturing engineering
In, it especially has higher requirements to fatigue behaviour and requires generally to have used in the welding structure engineering for eliminating residual stress.
Ultrasonic impact eliminates welding residual stress equipment and generally consists of two parts, and power supply and impact gun, the two pass through electricity
The connection of source line, man-hour manually hand-held impact gun when use, to weld impingement, since impact gun quality is bigger, and there is shake in while impacting
It is dynamic, worker's physical strength is consumed very much when working long hours.The big thickness of a large amount of high-strength steel is frequently present of in large-scale steel structure production at present
Plate welding point, such as the peripheral Collsion proof safety shell in nuclear power engineering, large pressurized vessel etc. exist in these steel constructions a large amount of
Long length is straight or regular weld seam, if these weld seams are impacted using conventional ultrasound eliminates welding residual stress machine to eliminate weldering
Power is scooped out, must be the engineering of a time and effort consuming, a large amount of manpowers is needed to handle, and for a large amount of straight or bending half
It is easier to realize mechanization, automatic welding for the biggish weld seam of diameter, while mechanization, automatic ultrasonic also may be implemented
Welding residual stress is eliminated in impact.
