1. Uhlolojikelele
I-Roll welding iwuhlobo lwe-resistance welding. Kuyindlela yokushisela lapho ama-workpieces ahlanganiswa khona ukuze akhe i-lap joint noma i-butt joint, bese ibekwa phakathi kwama-roller electrode amabili. Ama-electrode ama-roller acindezela i-weldment futhi ajikeleze, futhi amandla asetshenziswa ngokuqhubekayo noma ngezikhathi ezithile ukuze enze i-weld eqhubekayo. I-Roll welding isetshenziswa kakhulu ekwenzeni amalunga adinga ukubekwa uphawu, futhi ngezinye izikhathi isetshenziselwa ukuxhuma izingxenye zensimbi ezingavaliwe. Ubukhulu bezinto zensimbi ezishiselwe ngokuvamile buyi-0.1-2.5 mm.
Ama-Bellows asetshenziswa kuma-valve, ikakhulukazi ukuvalwa nokuhlukaniswa. Kuma-valve e-bellows ahlukahlukene, kungakhathaliseki ukuthi i-valve yokumisa, i-throttle valve, i-valve elawulayo noma i-valve yokunciphisa ukucindezela, i-bellows isetshenziswa njengento yokuhlukanisa ngaphandle kokupakisha kwe-valve yesiqu. Ngesikhathi sokusebenza kwe-valve, ama-bellows kanye ne-valve stem ziyasuswa futhi zihlelwe kabusha ndawonye. Ngesikhathi esifanayo, iphinde imelane nokucindezela koketshezi futhi iqinisekise ukuvala uphawu. Uma kuqhathaniswa nama-valve ophawu lokupakisha, ama-valve ama-bellows anokwethenjelwa okuphakeme nempilo yesevisi. Ngakho-ke, ama-valve e-bellows asetshenziswe kakhulu emkhakheni wemboni yenuzi, i-petroleum, imboni yamakhemikhali, imithi, i-aerospace, njll. Ekusetshenzisweni okungokoqobo, ama-bellows avame ukushiselwa kanye nezinye izingxenye ezifana nama-flanges, amapayipi kanye neziqu ze-valve. Izifutho zishiselwa nge-roll welding, esebenza kahle kakhulu futhi isetshenziswa kabanzi.
Ama-vacuum vacuum valves akhiqizwa yinkampani yethu asetshenziswa ezindaweni ze-uranium fluoride lapho okuphakathi kuvutha khona, kuqhume futhi kube nemisebe. Izifutho zenziwe nge-1Cr18Ni9Ti enogqinsi luka-0.12mm. Axhunywe ku-valve disc kanye ne-gland nge-roll welding. I-weld kumele ibe nokusebenza okuthembekile kokuvala ngaphansi kwengcindezi ethile. Ukuze kulungiswe iphutha futhi kuguqule imishini yokushisela ekhona ukuze ihlangabezane nezidingo zokukhiqiza, kwenziwa ukuhlolwa kwe-tooling design kanye nenqubo, futhi kwafinyelelwa imiphumela emihle.
2. Roll welding imishini
Kusetshenziswa umshini wokushisela i-FR-170 capacitor energy storage roll, enamandla okugcina amandla e-capacitor engu-340μF, uhla lokushintsha ugesi wokushaja ongu-600~1 000V, uhla lokulungiswa kwengcindezi ye-electrode engu-200~800N, kanye nesitoreji esiphezulu esingu-170J. . Umshini usebenzisa isekethe yokuma eyiziro evalelwe kusekethe, eqeda ububi bokuguquguquka kwamandla kagesi wenethiwekhi futhi iqinisekise ukuthi imvamisa yokushaya kanye ne-voltage yokushaja ihlala izinzile.
3. Izinkinga ngenqubo yokuqala
1. Inqubo yokushisela engazinzile. Ngesikhathi senqubo yokugoqa, indawo engaphezulu iqhuma kakhulu, futhi i-welding slag inamathela kalula ku-roller electrode, okwenza kube nzima kakhulu ukusebenzisa i-roller ngokuqhubekayo.
2. Ukusebenza kabi. Ngenxa yokuthi izifutho ziyanwebeka, ukushisela kulula ukuchezuka ngaphandle kokuma ngendlela efanele kwethuluzi lokushisela, futhi i-electrode kulula ukuthinta ezinye izingxenye zokuvuthela, okubangela izinhlansi nokuchaphaza. Ngemuva kwesonto lokushisela, iziphetho ze-weld azihambisani, futhi ukubekwa uphawu kwe-weld akuhlangabezani nezidingo.
3. Ikhwalithi ye-weld engalungile. I-weld point indentation ijule kakhulu, indawo engaphezulu ishisa ngokweqile, futhi kwenzeka ngisho nokushiswa okuncane. Ikhwalithi yokushisela eyakhiwe impofu futhi ayikwazi ukuhlangabezana nezidingo zokuhlolwa kwengcindezi yegesi.
4. Ukuvinjelwa kwezindleko zomkhiqizo. Ama-valve enuzi ayabiza. Uma kwenzeka ukusha, izifutho zizochithwa, okwandisa izindleko zomkhiqizo.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)
4. Ukuhlaziywa kwemingcele yenqubo eyinhloko
1. Umfutho we-electrode. Ngokufakwa kwe-welding, ingcindezi esetshenziswa yi-electrode ku-workpiece iyipharamitha ebalulekile ethinta ikhwalithi ye-weld. Uma ingcindezi ye-electrode iphansi kakhulu, izobangela ukushisa kwendawo yendawo-ngokusebenzisa, ukuchichima, i-spatter ebusweni kanye nokungena ngokweqile; uma ukucindezela kwe-electrode kuphezulu kakhulu, ukuhlehlisa kuyoba kujule kakhulu, futhi ukuguqulwa nokulahlekelwa kwe-electrode roller kuzosheshisa.
2. Isivinini se-Welding kanye nemvamisa ye-pulse. Ukuze uthole i-weld roll evaliwe, amaphuzu weld weld, ngcono. I-coefficient yokugqagqana phakathi kwamaphoyinti okushisela ingcono kakhulu ibe ngu-30%. Ukushintsha kwesivinini se-welding kanye nemvamisa ye-pulse kuthinta ngokuqondile ushintsho lwezinga lokugqagqana.
3. I-capacitor yokushaja kanye ne-voltage. Ukushintsha i-capacitor yokushaja noma i-voltage yokushaja kushintsha amandla adluliselwa endaweni yokusebenza ngesikhathi sokushisela. Indlela yokufanisa yamapharamitha ahlukene kokubili inomehluko phakathi kokucaciswa okuqinile nokubuthakathaka, futhi ukucaciswa kwamandla okuhlukile kuyadingeka ezintweni ezihlukene.
4. I-roller electrode end face form kanye nosayizi. Amafomu e-roller electrode asetshenziswa kakhulu wuhlobo luka-F, uhlobo lwe-SB, uhlobo lwe-PB nohlobo luka-R. Lapho ubukhulu bobuso bokuphela be-electrode ye-roller bungafaneleki, kuzothinta ubukhulu be-weld core kanye nesilinganiso sokungena, futhi kuzoba nomthelela othile kwinqubo yokushisela.
Njengoba izidingo zekhwalithi zamajoyinti we-roll weld zibonakala ngokuyinhloko ekubekweni uphawu okuhle kanye nokumelana nokugqwala kwamalunga, umthelela wokungena kanye nezinga lokugqagqana kufanele licatshangelwe lapho kunqunywa imingcele engenhla. Enqubweni ye-welding yangempela, imingcele ehlukahlukene iyathintana futhi kufanele ihlanganiswe kahle futhi ilungiswe ukuze kutholakale amajoyini we-roll weld wekhwalithi ephezulu.
