Summary: ? floats appendage crime writes Bi to closely question dusk adds hard apricot Mou of warbler of locust of dispatch of chirp α κ embraces of Nai serve Guo to pull of 4 mow to add Xi of border of bless α to seek Meng of take along sth to sb to buy Wan of enzymatic of Lai of of the austral Φ of the α that add bless to live ⒎ award, and solder the welding stress that exists in component part is the problem that nots allow to ignore, the carrying capacity that it is affecting a product directly, fatigue function, be able to bear or endure corrode sex, as the new method that eliminates stress------The application that gram of a person of extraordinary powers can eliminate welding stress equipment is right army the port with taste production to have principal. Gram of a person of extraordinary powers can eliminate welding stress equipment to have the following and clear technology advantage: · is current most comb-out remains pulls stress, the technique that produces an ideal to press stress (the condition that does not remove leftover stress with method of effectiveness for a given period of time is as follows: Oscillatory effectiveness for a given period of time 30 ～ 55% , hot effectiveness for a given period of time 35 ～ 80% , a person of extraordinary powers is overcome can effectiveness for a given period of time 80% above) ; · can make solder contact exhaustion intensity raises 50%-120% , fatigue life lengthens 5 times above; The Yu Gao that · manages solder foot, indentation, bite the direct processing such as the edge to be crossed into round glide, improve the geometrical appearance of solder foot effectively thereby, the stress that drops point of foot of welding line solder greatly centers coefficient; · makes welding line reachs his to heat up what influence area falls in corrosion environment to fight corrode ability to rise greatly; · is used at eliminating to solder leftover stress, can replace the method of effectiveness for a given period of time such as heat treatment and oscillatory effectiveness for a given period of time completely, and processing technology is simple, the effect is stable and reliable. Think where processing handles, can be on aleatoric time, aleatoric working procedure undertake; , suit to be opposite particularly so mechanical spare parts is local solder the processing that repair place undertakes elimination welding stress; · eliminates solder foot to locate the tiny flaw of surface layer and slaggy defect, restrain crackle produce ahead of schedule; · local aggrandizement is handled, in spare parts surface generation presses stress certainly (and beforehand of buy pressing stress to be worth size is can accuse) , improve quality of spare parts surface and fatigue life thereby; · can eliminate welding stress processing to be able to improve performance of exhaustion of influence welding line at the same time as a result of gram of a person of extraordinary powers the element of a few respects: Aggrandizement of appearance of solder foot geometry, leftover stress, microcosmic crackle and slaggy blemish, surface, can rise substantially consequently solder the fatigue intensity of contact and fatigue life. As a result of afore-mentioned special technology advantages, make gram of a person of extraordinary powers can eliminate welding stress equipment to be in army article solder get in the rehabilitate of the production of structural member and product more and more apply widely. 1, the application on aviation engine is right the leftover stress control that component part solders on aviation engine is very strict, there is what cannot let a plane take stress to go up to the sky to say inside course of study, 410 factories pass the each function experiment of ten months to prove: Gram of a person of extraordinary powers can eliminate welding stress equipment to achieve pair of aviation engine completely to solder the requirement that component part eliminates leftover stress, OK in the production of engine and maintenance applying. But belong to excel in thin plate as a result of capable person of stricture of space of aviation engine structure, mother, do not allow to produce processing trace in spare parts surface, so, developed gram of appropriative a person of extraordinary powers to be able to eliminate welding stress equipment for aviation engine according to the requirement of 410 factories, maintained a factory to receive very good application in this factory and other aviation engine. The Nextpage2, application on ship vessel maintenance is in the maintenance of pair of ship vessels, solder repair holds larger proportion, and often be repaired by solder place also is to bear fatigue load, seawater is corroded wait for the most serious place, if these place do not undertake after solder is repaired stress handles effectively disappear remains, can continue to produce similar loss in this place, maintain periodic meeting to become shorter even. In the meantime, soldering gram of a person of extraordinary powers is used to be able to eliminate stress processing to also can decrease greatly when repair solder be out of shape and phenomenon of the craze after solder. For example 4808 factories are right this technology was used in nuclear-powered submarine maintenance, after test data makes clear solder, leftover stress value is 200 ～ 285Mpa, stress of the remains after via a person of extraordinary powers the gram can eliminate stress to handle already by comb-out (the elimination of leftover stress is led in 99% above) , and go up to become ideal originally press stress. Dockyard of Nanjing gold hill is in twice to some ship after repair below the case that the sea tries to appear in solder to repair place to discover much place craze cannot make a boat after using gram of a person of extraordinary powers to be able to eliminate welding stress equipment to repair welding line to undertake handling to all solder, again the sea tries to did not discover one place flaw, make a boat smoothly, and the maintenance quality that this boat also praises this dockyard in the client in the following use process. Gram of a person of extraordinary powers can eliminate stress equipment commonly used still producing what discover in the process to cast at the airframe to ship vessel engine blemish and after using, discover wear away and corrode place to undertake soldering the processing after repair, solder in order to eliminate leftover stress. 3, the applied titanium alloy on titanium alloy weldment already was used in great quantities by the domain such as aviation, spaceflight, shipping, enginery, gram of a person of extraordinary powers can eliminate welding stress equipment to also get comparative extensive promotion in recent years in the application on titanium alloy weldment, its application solved titanium alloy to remove the long-standing issue of stress thoroughly. Some institute uses gram of a person of extraordinary powers to be able to eliminate the trial verdict that welding stress technology obtains to be: Limit of exhaustion of the connect after using gram of a person of extraordinary powers to be able to eliminate welding stress to Ti80 alloy cruciform joint rises 64.
5% , contact exhaustion life rises 13.
5 times; Solder leftover stress was reduced 85% , solder contact has effect force to centered coefficient to reduce 22% . 4, the early-warning plane radar that some institute produces the applied electron ministry on weapons ammunition, carriage appliance, be produced in its and gram of a person of extraordinary powers was used to be able to eliminate stress equipment in maintenance process, spot of the on the spot after the adoption of this kind of equipment also went to the lavatory to undertake to radar different ground solder is repaired greatly eliminates stress to handle. Because motor tricycle of military great horse power asks in abominable ground the environment leaves Sunday run failure free operation, the frame that produces by existing production methods cannot achieve army demand. Increasing data strength grade and the circumstance of the ply that use material to fall to be able to eliminate stress equipment to undertake handling to the main welding line of frame through using a person of extraordinary powers to overcome, fatigue function is obtained namely rise substantially, achieve check and accept a requirement. Solder to the cartridge of structural style and cartridge case often produce crackle because of be in place of its welding line and sign up for cost, and solder in cartridge and cartridge case stress equipment can be eliminated to be handled to welding line only with gram of a person of extraordinary powers after ending, won't produce craze phenomenon again. If undertake to cartridge mouth ministry gram of a person of extraordinary powers can be handled again, can reduce out of round of medical canister oral to spend greatly. Altogether, gram of a person of extraordinary powers can eliminate stress equipment to be in army taste a domain to already received wider and wider application, solved a few be in before eliminate leftover stress respect special a Gordian knot. It solders to eliminating not only leftover stress is having exceedingly good show, and, also rose to solder greatly at the same time the fatigue function of component part. CNC Milling
