Ikhwalithi Yokwakheka Kwe-Weld Engaguquki

Irobhothi le-spot welding liqhuba izinhlelo ezinamapharamitha we-welding ahleliwe. I-Welding current, ubude besikhathi bokushisela, ama-motion trajectories kanye nomfutho we-electrode kusetshenziswa ngendlela evamile evaliwe{1}}ngendlela eyiluphu kuyo yonke inqubo. Ama-welds angekho angaqedwa ngokuphelele, kuyilapho ukujula kokungena kanye nobukhulu bokushisela bawo wonke amaqoqo ezinto zokusebenza kufana kakhulu, kuletha ukungaguquguquki okulawulekayo kwikhwalithi yokushisela.

Ukusebenza Okuphezulu Kokukhiqiza

Okwekholomu-lohlobo lwendawo yokushisela, ukusebenza mathupha kukhawulelwe ukufinyeleleka komuntu. Ukushisela ezindaweni ezigobile eziyinkimbinkimbi noma ezindaweni zangaphakathi kudinga ukuhlakazwa okuphindaphindiwe, ukuhlanganisa kabusha kanye nokumiswa kabusha kwesakhiwo, okuholela ekuphumuleni okuyisiza okukhulu. Uma i-fixture isiboshiwe futhi ibekwe endaweni eyodwa, irobhothi lokushisela lincike{3}}ekuxhunyweni kwama-axis amaningi ukwenza ama-engeli ahlukahlukene kanye nezindawo, ukunciphisa kakhulu isikhathi sokuphumula esichithwa ekushintsheni kwezinto.

Ukulandeleka Okuqinile

Isilawuli serobhothi lendawo sirekhoda amapharamitha wokushisela kuwo wonke amaphoyinti okushisela, athobelana nekhwalithi yokugcinwa kwengobo yomlando eshiwo amasistimu okukhiqiza izimoto afana ne-IATF 16949.

Ukusebenza Okuzenzakalelayo Okuphephile

Ukukhiqiza okuzenzakalelayo kugcina o-opharetha bekude namazinga okushisa aphezulu, i-spatter yokushisela kanye nentuthu yokushisela eyingozi. Kuphinde kuvimbele ubunzima obungokomzimba obubangelwa ukuphatha mathupha izibhamu zokushisela ezisindayo, okubonisa ngokugcwele izinzuzo zokusebenza zerobhothi elishisela indawo ekukhiqizeni izimboni.

Indawo yokusebenza yerobhothi yokushisela incike ekusebenzeni okuhlanganisiwe kwamasistimu amathathu amakhulu: isibhamu esishiselayo esakha ama-weld nuggets, irobhothi lezimboni eligibelisa futhi limise isibhamu esishiselayo, kanye nesilawuli esivumelanisa ukunyakaza kwerobhothi nesikhathi sokushisela. Ukusebenza okuhambisanayo kwalezi zingxenye ezintathu kunquma kakhulu izinga lokushisela nokuzinza kokusebenza kwawo wonke umugqa wokukhiqiza.

Isibhamu sokushisela esilula se-pneumatic siyisilinda-i-driven resistance spot welding tong eyakhelwe ngokukhethekile amarobhothi ashisela amabala anomthamo womthwalo ongu-20 kg wezingcezu zokusebenza-ezinosayizi omaphakathi. Ihlanganisa ikakhulukazi izakhiwo ezimbili ezivamile:-uhlobo oluqondile lwe-C-idizayini yokucindezela kanye nomklamo wesikere wohlobo lwe-X-. Ithatha umzimba ongasindi futhi incike kusilinda somoya ekucindezelweni kokushisela okukhiphayo, ifakwe{8}}nezingalo ze-electrode ezipholile, i-valve elawula umoya womoya kanye nesistimu yokupholisa{9}}eyakhelwe kumjikelezo wamanzi, futhi ingagxunyekwa ngokuqondile{10}kundawo yokushisela yamarobhothi esihlakala.

Isisindo esiphelele sesibhamu esishiselayo, i-transformer nezintambo sinquma umthamo okaliwe werobhothi. Amapharamitha amathathu abalulekile kufanele abekwe phambili ngesikhathi sokukhetha imodeli:

Amandla okulayisha: Kumelwe isekele ukuhlanganiswa okugcwele kwesibhamu sokushisela nge-margin eyengeziwe yokuphepha egciniwe.

Irediyasi yokusebenza: Qinisekisa ukuthi isivalo se-electrode singafinyelela kuzo zonke izindawo zokushisela endaweni yokusebenza.

Inombolo Yezimbazo: Inquma ukuguquguquka kwerobhothi ukuze kugwenywe ukungqubuzana nezakhiwo eziyinkimbinkimbi zomsebenzi.

Yonke imisebenzi yokushisela indawo yerobhothi incike ezintweni ezimbili ezibalulekile:-umjikelezo wokushisela wesiteji ezine ukuze ukwakheka kwamalungu kanye nesethi yamapharamitha ayinhloko alawula inqubo yokushisela. Kuphela ngokuqonda ngokugcwele lezi zakhi ezimbili lapho ikhwalithi yokushisela ingalawulwa kancane kancane futhi kugwenywe ukuchezuka okufihliwe kumapharamitha wenqubo.

I-Resistance spot welding yakha ilunga ngalinye ngezigaba ezine ezilandelanayo. Ukushisa okudingekayo ekuhlanganisweni kwensimbi kuvela ekungangeni kukagesi kwengcezu yokusebenza esikhundleni samalangabi angaphandle noma izintambo zokugcwalisa. Ngemuva kokuthi ama-electrode ebopha amashidi ensimbi, amandla aphezulu ageleza ezintweni ezigqagqene. Ukushisa kwe-Joule (umphumela oshisayo we-I²R) kukhiqizwa ezindaweni ezincibilikayo ngenxa yokumelana nokuthintana, kugxile endaweni yokushisela futhi kuncibilike insimbi yendawo ibe yichibi elincane elincibilikisiwe. Uma i-welding current isinqamukile, ama-electrode ahlala eboshiwe ukuze kuvunyelwe ichibi elincibilikisiwe ukuthi liphole futhi liqine ngaphansi kwengcindezi, ekugcineni enze i-weld nugget{4}}ijoyinti elishiselwe langempela. Zonke ezinye izinyathelo ezisebenzayo zisebenzela ukudala nokubumba le nugget ye-weld.

Izinyathelo Eziningiliziwe Zokusebenza:

1. {0}Isiteji sengcindezi: Ama-Electrode ayavala futhi amandla okubamba akhuphukela kunani elimisiwe.

2. Isiteji Samanje Welding: I-Welding current ivuliwe, futhi izindawo zokuthintana zamashidi ziyancibilika ngaphansi kokushisa kokumelana.

3. Forge Holding Pressure Stage: Ukunikezwa kwamandla kuyanqanyulwa ngenkathi ama-electrode elokhu ecindezela, okwenza ichibi elincibilikisiwe liqine libe yi-weld nugget ecinene.

4. Isiteji sokukhipha: Ama-Electrode avuliwe, futhi irobhothi liya endaweni yokushisela elandelayo.

Inhlanganisela yamapharamitha enqubo (eyaziwa nangokuthi ishejuli yokushisela) inquma ukuthi ingakhiwa yini i-weld nugget efanelekayo:

1. I-Welding Yamanje(ezinkulungwaneni zama-ampere; ububanzi obujwayelekile bensimbi bucishe bube ngu-8,000 kuya ku-15,000 ama-ampere): Amandla anganele ahluleka ukwakha i-weld nugget evumelekile, kuyilapho ubuningi bamanje bubangela i-spatter yensimbi encibilikisiwe.

2. Amandla{0}engcindezi yangaphambili(ngamakhulu ama-newtons noma amaphawundi{0}}amandla): Ukucindezela okunganele kubangela kalula i-spatter yokushisela; ukucindezela ngokweqile kwenza amashidi ensimbi abe mncane futhi kunciphisa usayizi we-weld nugget.

3. Isikhathi Sokushisela(kukalwa ngemijikelezo ye-AC noma ama-millisecond): Isikhathi sokushisela esifushane siyamukelwa kumashidi amancane, kuyilapho ubude besikhathi budingeka kumapuleti awugqinsi.

4. Isikhathi Sokubamba: Ukucindezela okuqhubekayo kusetshenziswe ngemva kokunqunywa kwamandla ukuze kuqinisekiswe ukuqina okuphelele, okuqinile kwe-weld nugget.

5. Duty Cycle: Inombolo ephezulu yokushisela okulandelanayo isibhamu esingakwazi ukukwenza ngaphambi kokudinga isikhathi sokuphumula sokupholisa, okuphinde kuchaze umthamo wangempela ophezulu womugqa wokukhiqiza.

Ukuze ubone ukuthi siyafaneleka yini, beka imfuneko yangempela phambi kukanjiniyela. Thumela ingxenye yakho yomdwebo, isikhathi somjikelezo, kanye nemikhawulo yeseli, futhi sizobuya nokucushwa nesikhathi sokuhola.
