Ukushisela Ikalishi likaRhino: Kungani Umhlangano Oqinile Wozimele Uqala Ngaphambi Kwe-Arc Yokuqala
Unqamule ishubhu. Womile-wahlanganisa amalunga. Usukulungele ukushaya i-arc kuhlaka lwenqola yakho ye-Rhino—futhi yilapho kanye ukwakhiwa kwe-DIY okuningi kuhluleka khona. Hhayi kusukela kunsimbi ebuthaka, kodwa kusukela ekushiseni okungalawuleki, ukungena okungahambisani, noma izinto ezilungiswe kabi. Sihlanganise ozimele bezinqola zangokwezifiso ezingaphezu kuka-12,000 e-Botou Haijun Metal Products Co., Ltd.—hhayi njengezibonelo, kodwa ukuze zisetshenziswe ensimini ezivini zaseNyakatho Melika, izifutho zezithelo zase-Europe, nabavuni irayisi baseNingizimu-mpumalanga Asia. Esikubona nsuku zonke akuyona inkolelo-mbono. Iba amalungu asontekile ngemva kokudlula okukodwa. Ama-gussets aqhekekile ngaphansi kuka-300 kg womthwalo okhokhelwayo. Imicu ekhumula emigodini efakwayo ngoba i-base plate ihlanekezelwe ngesikhathi sokushisela.
Ukushisela inqola kaRhino okuqinile akukho mayelana ne-amperage noma i-filler wire yodwa. Kumayelana nokulandelana, ukuzibamba, nokuziphatha kwezinto ezibonakalayo. Insimbi egoqekayo—izinga lethu lamafreyimu e-Rhino—linweba u-12.5 µm/m·°C. Isitimela esiseceleni esingama-600 mm esishiswe sibe ngu-400°C ngaphandle kokucisha sizokhula cishe ngo-3 mm ngaphambi kokupholisa. Lokho kukhula akushabalali. Ivala ingcindezi eyinsalela. Futhi ukuphuka kokucindezeleka akubonakali ngesikhathi sokushisela-kodwa phakathi nomjikelezo wesithathu womthwalo.
Izinyathelo Ezintathu Ezingaxoxiswana Ngaphambi Kokushisela
Ukweqa noma yikuphi kwalokhu kushintsha inqola yakho ye-Rhino isuke ethuluzini iye kwisibopho sezomthetho:
Lungisa wonke amalunga-hhayi nje amaphuzu we-weld. Sebenzisa amajigi e-engeli ensimbi anezitobhi ezilungisekayo. Bamba umjikelezo wonke wobakaki ngamunye, hhayi nje umthungo wokushisela. Sithole ukuthi amakhona angavaliwe ashintsha aze afike ku-1.8° ngesikhathi sokudlula kwezimpande—okwanele ukuze aqondise kahle izikhwezi zamasondo ngo-4.2 mm ekuphakameni kwe-ekseli. I-tack kusengaphambili ngezikhawu ezingu-10-mm—futhi uqinisekise isikwele kabili. Ama-tack weld kufanele angene ngokugcwele, angabi ama-dabs angaphezulu. Ngemva kokuqopha, kala ama-diagonal ngaphesheya kukanxande oyinhloko. Umehluko > 1.5 mm usho ukuthi ukuhlanekezela kuyakha. Gaya futhi uphinde ubambe. Ungaqhubeki. Shisisa kuqala kuphela uma i-ambient yehla ngaphansi kuka-10°C—noma usebenzisa > ishubhu yodonga engu-3-mm. Ngensimbi evamile egoqelwe ebandayo engu-2-mm (Q235 noma i-ASTM A1008), ukushisa kwangaphambili kwengeza ingozi enkulu kunenzuzo. Ukuhlolwa kwethu kwesifutho sikasawoti kubonise amalunga ashisiwe ngaphambilini agqwalile ngo-27% ngokushesha ezinzwaneni ze-weld ngenxa yokwakheka kongqimba lwe-oxide olushintshile. Kungani i-"Weld It" Ihluleka Njalo
Abanye baphikisa ngokuthi ukushisela kwe-MIG kuthethelela ngokwanele kumafreyimu enqola. Kepha imininingwane yethu ye-CMM ixoxa enye indaba. Ezinqoleni ezingu-147 ezihlolwe ngokungahleliwe zesitayela sikaRhino ezakhiwe abathandi bokuzijabulisa, ama-68% abonise ukuchezuka kwe-angular > ±2.3° emajoyini ekhona. Ngu-11% kuphela ophase ukuhlolwa kokusebenza ngomthwalo ophelele. Imbangela? Ukungahambisani kwesivinini sohambo. Ukwehla ngo-15% kwejubane lokuhamba kwandisa okokufaka kokushisa ngo-34%. Lokho kuncibilikisa insimbi eyisisekelo eyengeziwe, kunwebe indawo ethinteke ukushisa (HAZ), futhi kuthambisa isakhiwo sokusanhlamvu esiseduze nendawo yokushisela. Umphumela: imifantu yokukhathala iqala emingceleni ye-HAZ ngemva kwamahora okusebenza angu-1,200–1,800—hhayi iminyaka kamuva.
Sisebenzisa i-pulsed MIG kukho konke ukukhiqiza ozimele benqola ye-Rhino. Imvamisa ye-Pulse ihlala imile ku-120 Hz. I-Peak current ibamba ku-185 A. Ingemuva lamanje lehla liye ku-42 A. Lokhu kuletha ukudluliswa kwamaconsi okunembile, kunciphisa i-spatter ngo-70%, futhi kugcina ububanzi be-HAZ bungaphansi kuka-1.1 mm—ngisho nakumashubhu angu-2.5-mm. Kwabashisela be-DIY abangenawo amandla okushaya kwenhliziyo? Sebenzisa i-short-circuit transfer, gcina u-stick-out ngaphansi kuka-12 mm, futhi uhambe ku-35-40 cm/min. Noma yini ehamba kancane imema ukushiswa. Noma yini esheshayo imema ukushoda kwe-fusion.
Izindleko Zangempela Zokushisela Ikalishi likaRhino
Akukhona nje ukwehluleka kwesakhiwo. Ama-welds abuthakathaka ashayela izindleko ezifihliwe:
Ukusebenza kabusha: Ukugaya i-gusset ephukile kuthatha imizuzu engu-22. Ukuyishisela kabusha ngendlela efanele—ngokulawula izinga lokushisa elifanele—kwengeza okunye okungu-18. Lokho imizuzu engama-40 elahlekile ngokuhlanganyela. Kuhlaka olugcwele? Ngaphezu kwamahora ama-3. Udoti wezinto ezibonakalayo: Isitimela esiseceleni esisodwa esihlulekile sisho ukuklwebha womabili amareyili—ngoba ukumadanisa okusanhlamvu kanye nokuqedwa kwe-post-weld akunakwenzeka ngaphandle kwe-mill-level annealing. Isikhathi sokuphumula senkundla: Inqola ehlulekayo ekuvuneni ibiza u-$190/ihora emsebenzini olahlekile nesikhathi sokungenzi lutho kwemishini. Amakhasimende ethu abika isilinganiso sesikhathi sokulungiswa sokuhluleka okuhlobene nokushisela: izinsuku eziyi-11.3. I-Botou Haijun igwema lokhu ngokuphoqelela imikhawulo yezinga lokushisa elingu-≤150°C. Siqapha yonke i-weld nge-infrared thermography—hhayi ukuqagela. Uma izinga lokushisa likhuphuka ngaphezu komkhawulo, siyama kancane. Siyalinda. Siyapholisa. Akukho okuhlukile.
Okusebenzayo-Futhi Okungasebenzi-kumafreyimu enqola ye-Rhino
Sihlole imikhuba emihlanu evamile kuwo wonke amasampula e-weld angama-420. Nakhu okwabambile:
Umumo we-Gusset ubalulekile. Ama-gussets angunxantathu anemilenze engu-45° asebenza kangcono kuneyonxande ngo-41% ekuhlolweni kokuqina kwe-torsional. Amakhona erediyasi kumathiphu e-gusset ehlise ukugxilisa kwengcindezi ngo-63% (kukalwa ngamageji ohlobo). Indlela yokushisela ilawula ukuhlanekezela. Ukushisela kusuka phakathi kuya ngaphandle kojantshi abade kunqamule ukugoba ngo-82% uma kuqhathaniswa namaphasi okuqala ukuya ekupheleni. Ukulandelana: phakathi nendawo → iphoyinti ¼ → iphoyinti ¾ → iziphetho. Ukukhululeka kwengcindezi yangemva kokushiswa akukona ukukhetha kumthwalo okhokhelwayo >250 kg. Sibamba amafreyimu ku-580 ° C imizuzu engu-45 ezithandweni ezilawulwayo. Ukupholisa komoya ngemva kokukhulula u-94% wengcindezi esele. Ukweqa lesi sinyathelo kunyuse izinga lokuqalisa kokuqhekeka ngo-5.7× ekuhloleni ukuphila okusheshisiwe. Inothi elilodwa lokugcina: Ukushisela ikalishi likabhejane akuphathelene namandla anonya. Imayelana nokubikezelwa, ijometri ephindaphindwayo. Yonke insimbi kufanele isebenze ebandleni, ingahlanganisi iziqephu ezimbili. Lowo mqondo wehlukanisa izinqola ezihlala amasizini amahlanu kulawo alahliwe ngemuva kweyodwa.
Uma uzimele wenqola yakho ye-Rhino udinga ukushiselwa okunembayo okusinda emithwalweni yomhlaba wangempela, i-Botou Haijun Metal Products Co., Ltd. inikeza ukwakhiwa kwezinga lobunjiniyela—okwakhelwe phezu kwensimbi egoqwe ebandayo, eqinisekiswa nge-CMM nokuhlola okuqinile, futhi kusekelwe ukulawulwa kwenqubo eqondaniswe ne-ISO. Asizithengisi izingxenye. Siletha isiqiniseko sobukhulu.
