Emkhiqizweni wezimoto, izivalo zebhethri zamandla amasha, kanye nokwakhiwa kweshidi lensimbi, iumshini wokushisela indawoidlala indima ebalulekile ekukhiqizweni kwansuku zonke. Phakathi nesigaba sokuthenga, izinkampani eziningi zigxila kakhulu kumthamo wamandla, ububanzi bamanje, nezinhlelo zokulawula, nokho zishaye indiva indaba engokoqobo: ukuthi okokusebenza kungakwazi yini ukugcina ukusebenza kahle okuzinzile esikhathini eside nokuthi ukunakekelwa okujwayelekile kuqondile futhi kuyalawuleka.
Idatha yasensimini ibonisa ukuthi imishini yokushisela i-medium frequency inverter spot ngaphandle kokulungiswa okujwayelekile ingaba nokwehla ngo-15%–25% ekusebenzeni kahle komjikelezo wokushisela, kanye nokwenyuka okuphawulekayo kwesikhathi sokuphumula esingalindelekile. Ukusetshenziswa kwe-Electrode kuyenyuka, amanani okusebenza kabusha akhuphuka, futhi izindleko zokusebenza ezifihliwe zidlule ngokushesha okulindelwe. Esikhundleni sokusabela ekuqhekekeni, ukuhlelwa kokulungisa okuhlelekile kusiza ukuvimbela ukulahlekelwa okusebenzayo ngaphambi kokuthi kuthinte umkhiqizo wokukhiqiza.
Kungani Ukunakekelwa Kokuvamile Kuthinta Ngokuqondile-Ukusebenza Kwesikhathi Eside
Ikhwalithi Yokushisela Incike Ekuzinzeni Kwesistimu, Hhayi Kuphela Izilungiselelo Zamanje
Umshini wokushisela indawo ye-frequency emaphakathi usebenzisa ubuchwepheshe be-inverter ukuletha-impendulo esheshayo, elawulwa ngokunembile DC welding current. Kodwa-ke, ikhwalithi ye-weld yangempela incike ngaphezu kwamapharamitha kagesi. Isimo se-electrode, ukungaguquguquki kwamandla okubamba, ukusebenza kahle kokupholisa, nokuzinza kwesistimu yokulawula konke kusebenza ndawonye.
Uma okunye kwalokhu okuguquguqukayo kukhukhuleka, usayizi we-weld nugget namandla kungashintsha ngisho nalapho imanje elihleliwe lihlala lingashintshile. Ukunakekelwa okujwayelekile kuqinisekisa ukuthi amasistimu kagesi, ama-mechanical, kanye ne-thermal ahlala elinganiselwe ngokuhamba kwesikhathi.
Ukulahleka Kwempumelelo Kuthuthuka Kancane Kancane
Ukwehla kokukhiqiza akuvamile ukwenzeka ngobusuku obubodwa. Izimpawu eziyisixwayiso zakuqala ngokuvamile zihlanganisa imijikelezo yokushisela ehamba kancane, ukugqoka ama-electrode kaningi, opharetha abalungisa ngokuphindaphindiwe imingcele, nokuncipha kokuvumelana kwe-weld. Uma zizitshwa, lezi zinkinga ezincane ziyanqwabelana futhi ekugcineni zibangele ukuvalwa kwemishini.
Indlela yokulungisa yokuvimbela inciphisa isikhathi sokuphumula esingahlelelwe futhi izinze okukhiphayo kuzo zonke izikhathi zokukhiqiza ezinde.
Izenzo Ezinhlanu Ezibalulekile Zokulungisa Ukuze Kuthuthukiswe Ukusebenza Komshini Welding Wendawo
Ama-Electrode Ahlanzekile Nokulungiswa Nsuku Zonke Ukuze Ugcine Ukumelana Okuqinile Kokuxhumana
Izendlalelo ze-oxidation noma i-weld spatter kumathiphu we-electrode zandisa ukumelana nokuxhumana, okubangela ukusatshalaliswa kwamanje okungalingani kanye nokushisa okweqile kwendawo. Lokhu kuthinta ngqo ukwakheka kwe-nugget kanye nokuvumelana kwe-weld.
Ekupheleni kweshifti ngayinye, gqoka amathiphu e-electrode usebenzisa isigqoko sethiphu esifanele futhi uhlole izindawo zokulungisa izinto ukuze uthole ukungcola. Ukugcina ubuso be-electrode obuhlanzekile, obuyisicaba kubaluleke kakhulu{1}}ezinhlelweni zevolumu ephezulu ezifana nezindawo zokukhiqiza umshini wokushisela indawo yezimoto, lapho ukuvumelana kuthinta ngokuqondile ubuqotho besakhiwo nokusebenza kwayo.
Hlola Ukugeleza Kwamanzi Okupholisa Nekhwalithi Ukuze Uvikele Izingxenye Eziyinhloko
Amamojula e-IGBT nama-welding transformer akhiqiza ukushisa okubalulekile-kumijikelezo ephezulu yomsebenzi. Uma ukusebenza kahle kokupholisa kwehla, izingxenye zangaphakathi ziwohloka ngokushesha futhi zingase ziqalise ukuvalwa kokuvikela okushisayo.
Ngaphambi kokuqala imisebenzi yansuku zonke, qinisekisa ukugeleza kwamanzi okuzinzile nokucindezela. Njalo hlola ukuqhutshwa kwamanzi ukuze uqinisekise ukuthi ahlala ngaphakathi kwemikhawulo enconyiwe, futhi uhlanze izihlungi ukuvimbela ukukala noma ukuvinjwa.
Emshinini{0}wokushisela indawo wemboni olayisha kakhulu wezinhlelo zokusebenza zeshidi lensimbi, isistimu yokupholisa ethembekile ibalulekile ekugcineni umthamo wokukhiqiza ongashintshi.
Qinisa Uxhumano Lwe-Pneumatic kanye Nemishini Ukuze Uqinisekise Amandla Okushisela Okungaguquki
Ukuzinza kwamandla okushisela kubalulekile ekwakhekeni kwe-nugget okungaguquki. Ukukhweza okuxegayo kwamasilinda, izingalo ze-electrode ezingaqondani kahle, noma ukunyakaza{1}}okubangelwa ukudlidliza kungabangela ukuhlukahluka kwamandla, okuholela kusayizi wokushisela okungahambisani namandla.
Yenza ukuhlolwa kwetorque yamasonto onke ekuxhumekeni kwesakhiwo okubalulekile ngokuya ngemininingwane yomkhiqizi. Njalo qinisekisa ukuqondanisa kwengalo ye-electrode kanye nokuphindaphinda ukuze ugcine ukulawulwa kwengcindezi okunembile.
Qinisekisa Ukungaguquguquki Kwepharamitha Ye-Welding Nyanga Zonke ukuze Uvimbele Ukukhukhuleka
Ngokusebenza okunwetshiwe, ukuchezuka okuncane ekulinganisweni kwamanje noma kwamandla kungase kwenzeke. Lezi zinguquko zivame ukukhula kancane kancane futhi zingase zingabangeli ama-alamu ngokushesha, kodwa zingathinta ikhwalithi yokushisela ngokuhamba kwesikhathi.
Yenza ama-weld wokuhlola ajwayelekile njalo ngenyanga, ulinganise ububanzi be-nugget namandla okudonsa, futhi uqhathanise imiphumela namabhentshimakhi omlando. Izinhlelo zokulungisa umshini wokushisela i-Midium frequency inverter ezihlanganisa ukugawulwa kwedatha nokuhlaziywa kwethrendi kuvumela abakhiqizi ukuthi bathole ukushintsha kokusebenza okucashile ngaphambi kokuthi kuthinte ikhwalithi yomkhiqizo.
Buyekeza Isofthiwe Yokulawula kanye Nezinhlelo Zokushisela Esemuva
Izibuyekezo ze-Firmware ngokuvamile zihlanganisa ukuthuthukiswa kwe-algorithm, izithuthukisi zokuzinza, nokusekelwa okunwetshiwe kwezinto. Ukwehluleka ukubuyekeza isistimu kungase kuvimbele umshini ekusebenzeni ngendlela efanele.
Ngaphambi kokwenza ngcono, yenza ikhophi yasenqolobaneni yazo zonke izinhlelo zokushisela futhi ugcine amarekhodi epharamitha ahlelekile. Okokusebenza okusekela ukuhlonza okukude nezibuyekezo zesofthiwe kunciphisa kakhulu isikhathi sokunakekela futhi kunciphise ukuphazamiseka kokukhiqiza.
Ungawukhetha Kanjani Umshini Wokushisela Wendawo Oqinile Kakhudlwana Kumbono Wokulungisa
Lapho behlola okokusebenza, abathengi abaningi bagxila ezindlekweni zokuthenga ekuqaleni kuyilapho bebheka{0}}izindleko zesikhathi eside zokusevisa kanye nezindleko zomjikelezo wokuphila. Empeleni, ukunethezeka kokugcinwa kunomthelela kakhulu emvelweni jikelele.
Idizayini Yesakhiwo Eyenza Lula Ukunakekela
Imishini-yekhwalithi ephezulu ivamise ukufaka izakhiwo ze-modular ezinamasistimu kagesi ahlukaniswe ngokusobala, okupholisa umoya, nawewomoya. Shintsha{{2}amadizayini ama-electrode asheshayo, izihlungi ezifinyeleleka ngaphandle, nezinkomba zokugeleza kwamanzi ezibonakalayo kunciphisa isikhathi sokulungisa futhi kuthuthukise isikhathi sokukhiqiza.
Izici Zokuvikela Eziphelele
Amasistimu athuthukisiwe afaka ukuqapha ukugeleza kwamanzi,{0}}ukuvikela izinga lokushisa elingaphezulu, nama-alamu amanje angajwayelekile. Lezi zivikelo zivikela izingxenye ezibalulekile kanye nabaqhubi abaqaphile ngaphambi kokuba izinkinga ezincane zikhule zibe ukwehluleka okukhulu.
Lawula Amasistimu Anamandla Okuphatha Idatha
Imishini yesimanje yokushisela indawo kufanele isekele ukugawulwa kwepharamitha, ukuthekelisa idatha yomlando, nemisebenzi yokulandeleka. Ama-algorithms okulawula okuzinzile anokumelana nomsindo oqinile aqinisekisa okukhiphayo okungaguquki kuyo yonke imijikelezo yokukhiqiza emide kanye nokuthuthukiswa kwenqubo yosekelo.
Isiphetho
Ukusebenza kahle okuphezulu emshinini wokushisela amabala aphakathi nendawo akwenzeki ngephutha. Kuvela ezinkambisweni zokunakekela ezinezigwegwe ezigcina uzinzo kuwo wonke amasistimu kagesi, emishini, nawokupholisa.
Ngokuhlanza ama-electrode nsuku zonke, ukuqapha izinhlelo zokupholisa, ukuqinisa imihlangano yemishini, ukuqinisekisa ukungaguquguquki kwepharamitha, nokuvuselela isofthiwe yokulawula, abakhiqizi bangakwazi ukuthuthukisa ukusebenza kahle ngokuhlelekile, ukunciphisa isikhathi sokuphumula, nokwelula isikhathi sokuphila kwemishini.
Ezinkampanini ezihlola ukuthengwa komshini wokushisela, ukucaciswa kokusebenza kanye nentengo kufanele kucatshangelwe ngokuhambisana nokugcinwa -nokuqina kwesikhathi eside. Indlela egxilile yomjikelezo wokuphila{2}iqinisekisa kokubili izinzuzo zokukhiqiza nokulawulwa kwezindleko ngokuhamba kwesikhathi.
