Ama-Welds Abuthakathaka Emishinini Yokushisela Yesitoreji Samandla?

Ekukhiqizeni ukunemba kwesimanje, iUmshini wokushisela isitoreji samandlaisibe yisisekelo sokushisela izingxenye zezimoto, izingxenye zikagesi,{0}}nezinsimbi ezingenayo insimbi. Izinzuzo zayo eziyinhloko zihlanganisa izikhathi zokukhipha ezimfushane kakhulu (imvamisa engu-3ms ukuya ku-15ms) kanye nomthelela omncane kugridi yamandla.

Kodwa-ke, abakhiqizi abaningi balwa namandla e-weld angahambisani noma "ama-welds abandayo" ngesikhathi sokukhiqiza. Lezi zinkinga azikhulisi nje kuphela amanani ezinto ezilahliwe kodwa futhi zibeka izingozi ezinkulu zokuphepha. Lesi sihloko sinikeza ukujula okujulile kwezobuchwepheshe ezimbangela zokushisela okubuthakathaka futhi inikeza amasu okuthuthukisa afinyelelekayo kanye neziqondiso zokuthenga.

1. Ukungalingani Phakathi Kwe-Welding Amandla namapharamitha

Ukukhishwa kwamandla omshini wokushisela wesitoreji samandla kulandela ifomula engokoqobo ethi $E=\\frac{1}{2}CU^2$ (lapho u-E engamandla, u-C enamandla, kanye no-U engumbane wokushaja). Ama-opharetha amaningi athembele kuphela ku-intuition ukuze alungise i-voltage kuyilapho beziba ukuvumelana kokuphuma kwamandla. Uma i-voltage isethwe iphansi kakhulu, ukushisa kwe-Joule okuwumphumela akwanele ukuncibilikisa insimbi, okuholela "ekushiseleni okubandayo."

Ngokuphambene, amandla amaningi abangela ukuxoshwa kwensimbi okunzima (i-spatter), okwenza izikhala ngaphakathi kwe-weld nugget. Amazinga emboni aphakamisa ukuthi ukushintshashintsha kwe-voltage ngokunemba okuncane-ku-plate welding kufanele kugcinwe ku-±1% ukuze kuvinjelwe ukuguquguquka okukhulu kobuqotho be-weld.

2. I-Pressure Mechanism "Ukulandela" kanye namaphutha Ezinombolo

Ukushisela isitoreji samandla kuhilela ukuqhuma okuqhumayo esikhathini esifushane kakhulu, okudinga ukulandela okukhethekile okuvela kumshini wokucindezela wekhanda lokushisela. Uma kukhona ukungqubuzana kwe-cylinder ngokweqile noma inertia ephezulu yemishini, ingcindezi ayikwazi ukusetshenziswa ngokushesha njengoba insimbi incibilika. Le lag idala i-arc kusixhumi esibonakalayo se-weld, okuholela "ekuqhumeni" noma izakhiwo zangaphakathi ezinezimbotshana.

Ngokuvamile, ingcindezi yokushisela yezingxenye ezincane ezinembayo kufanele isethwe phakathi kuka-500N no-1200N, kuyilapho izingxenye ezinkulu zesakhiwo zingadinga ngaphezu kuka-2000N. Ukucindezela okukhulu kunciphisa ukumelana nokuxhumana kakhulu, okuholela ekushiseni okunganele, kuyilapho ukucindezela okunganele kubangela ukushiswa kwendawo ngenxa yokumelana okuphezulu.

3. "Sub-optimal" Electrode Condition

Ama-Electrode asebenza kokubili njengamakhondatha kagesi kanye namathuluzi okuthwala umthwalo obonakalayo-. Ngokuhamba kwesikhathi, ama-electrode enza izendlalelo ze-oxide noma ashintsheke epulasitikini (okwaziwa kabanzi ngokuthi "amakhowe"), okwenza ukuminyana kwamanje kwehle.

Isibonelo, uma umkhawulo wethiphu ye-electrode ukhuphuka usuka ku-5mm ukuya ku-6mm, indawo yokuxhumana ikhula ngo-44%, kwehlisa ngempumelelo ukuminyana kwamanje cishe ngengxenye yesithathu.

Ochwepheshe batusa ukusebenzisa i-Chromium Zirconium Copper (CuCrZr) noma i-Beryllium Copper futhi kwenziwe ukufaka kabusha kabusha okujwayelekile njalo ngokushisela okungu-500 kuya ku-1,000 ukuze kugcinwe ukusebenza okuphezulu.

4. I-Microscopic Surface Ukungcola

I-welding yokugcina amandla izwela kakhulu esimweni esiphezulu se-workpiece. Isikali, ukugqwala{1}}amafutha avimbelayo, noma ukucwenga okungalingani kungashintsha kakhulu ukumelana nokuxhumana. Ku-copper-kuya{4}}ku-aluminium welding, isibonelo, ukumelana kwefilimu ye-oxide kuphezulu kakhulu kunokwensimbi eyisisekelo.

Ngaphandle kokuhlanza nge-ultrasonic noma ukufakwa kwamakhemikhali, ukushisa kugxila phezulu kunomnyombo we-nugget. Lokhu kudala "ibhondi engaphezulu" ekhohlisayo lapho ingaphakathi lihlala lingancibilikile, lihluleka nakanjani-ukuhlolwa kwethebhu noma ukugunda.

1. Ukulinganisa Okunembayo: Ukusungula Ilabhulali Yepharamitha Ye-Dynamic

Abakhiqizi kufanele basungule ama-matrics wepharamitha asezingeni ngokusekelwe kugqinsi lwempahla nohlobo. Ithebula elilandelayo linikeza isisekelo sezinto ezivamile; lokhu kufanele kulungiswe{1}}kusekelwe emiphumeleni yokuhlola yokudonsa{2}}kwangempela:

2. Ukugcinwa Nokuthuthukiswa: "Ukuhlola" Okujwayelekile kwama-Capacitor nama-Electrodes

I-capacitor "inhliziyo" yomshini wokushisela we-Energy storage. Ama-capacitor-ekhwalithi ephansi angase ahlupheke ngenxa yokubola kwamandla ngemva kokusetshenziswa{2}}imvamisa ephezulu isikhathi eside. Lokhu kusho ukuthi noma ngabe i-voltage setting ihlala ingashintshile, ukuphuma kwamandla kwangempela kwehlile.

Sincoma ukuhlolwa kwekota ngemitha ye-capacitance yochwepheshe; uma ukubola kudlula i-10% yenani elibizayo, i-capacitor kufanele ishintshwe ngokushesha. Ukwengeza, ukugcinwa kwelogi evuselelwe kabusha yama-electrode kuqinisekisa ingcindezi engaguquki kuwo wonke amaphuzu we-weld.

Uma okwamanje usemakethe yezinto ezintsha, lezi zindlela ezintathu zizokusiza ukuthi ubone umshini wokushisela{0}}osebenza kakhulu wesitoreji samandla:

1. Isici seProvenance:Beka kuqala imishini efakwe ama-capacitor akhethekile aphezulu-emvamisa yokukhishwa okuvela ezinkampanini ezihlonishwayo (isb., i-Nippon Chemi-Con, Rubycon). Lokhu ngokuvamile kunikeza isikhathi sokuphila sezigidi zemijikelezo, edlula kude ama-capacitor ezimboni ajwayelekile.
2. I-Digital Control Sophistication:Imishini-ephezulu kufanele ibe nobuchwepheshe bokushaja{1}bamanje kanye nesinxephezelo{2}}se-loop voltage evaliwe. Ngisho noma igridi yamandla embonini ishintshashintsha phakathi namahora aphakeme, isistimu yokulawula kufanele ilungise ngokuzenzakalelayo isikhathi sokushaja ukuze iqinisekise ukuhambisana okuphelele kukho konke ukukhishwa.
3. Ukunemba Kwendlela Yokucindezela:Hlola ukuthi ingabe umshiseli usebenzisa-amasilinda afriction aphansi noma amasistimu okucindezela okuqhutshwa yi-servo{1}}. Ukulandela okuphakeme kunciphisa kakhulu i-spatter futhi kubangele indawo yokushisela ebushelelezi, enhle kakhulu{3}}ebalulekile ekuthumeleni{4}}izingxenyekazi zekhompuyutha ezinembayo.

Isiphetho

Ukuxazulula inkinga yokushisela okubuthakathaka emshinini wokushisela wesitoreji samandla kudinga okungaphezu nje "kokulungiswa okusheshayo" noma ukulungiswa okungahleliwe. Ngokusebenzisa ukulinganisa ipharamitha yesayensi, ukulungiswa kwendawo okuqinile, nokuhlola impilo yemishini evamile, abakhiqizi bangakha-isistimu yokulawula ikhwalithi evaliwe.

Lokhu akugcini nje ngokuthuthukisa ukuncintisana kwemakethe kodwa futhi kunciphisa izindleko zokukhiqiza zizonke ngokuhamba kwesikhathi. Ezinseleleni eziyinkimbinkimbi ze-metallurgical, kuyatuseka ukuthintana nabahlinzeki abanezitifiketi ze-ISO futhi abanolwazi oluningi lwemboni ukuze kuthuthukiswe izixazululo zenqubo yokushisela.
