I-galvanized body welding: indlela yokupheka, izinhlobo zokushisela
Okuqukethwe
Abanikazi abaningi bemishini bakhetha ukupheka izimoto ngale ndlela, ngoba i-galvanized seam ingaphezulu, iyunifomu futhi iyunifomu, ikhwalithi isezingeni eliphezulu.
Inqubo evamile njenge-galvanized welding of the body inomthwalo wemfanelo, ibonakala ngamazinga okushisa aphansi okusebenza ngesikhathi sokuncibilika kwezinto ezikhethekile zokugcwalisa.
Ngisho nabaqalayo abaye bazijwayeza kahle nge-algorithm yezenzo bazobhekana nokulungiswa kwemoto, kodwa noma yikuphi ukunganakwa kobuchwepheshe kuzoholela ekushiseni kongqimba oluvikelayo lwensimbi, futhi uxhumano luzoqhekeka noma luphule.
Odinga ukukwazi mayelana ungqimba zinc kanye ukushuba yayo
Ngenxa yokungasebenzi kahle kwesendlalelo sokuzivikela, ochwepheshe babheka ukushisela umzimba wemoto njengomsebenzi onzima. Impahla eyengeziwe ene-copper-silicon noma ingxenye ye-aluminium-bronze yomsebenzi izosiza ukufeza uxhumano lwekhwalithi ephezulu.
Ebhekene nama-punctures amancane, ngaphambi kokushisela umzimba nge-galvanizing, ububanzi bomgodi bubuyiselwa kusayizi we-18-20 mm. Futhi indawo yangaphakathi yenziwa bushelelezi ngangokunokwenzeka, iminonjana yentambo, ukugqwala noma okunye ukungcola akwamukeleki.
Ungawupheka kanjani umzimba wamagalvanized
Phakathi kwama-nuances abalulekile lapho kulungiswa imoto, kufanelekile ukugqamisa incazelo yobuchwepheshe bokugqoka umkhiqizo, ungqimba oluvikelayo lungaba nobukhulu obuhlukahlukene. Uma upheka insimbi ngamashidi ambozwe ngefilimu yamandla, ukushisa kwenzeka ngokuzumayo, kuze kufike ekushiseni okungama-degree ayizinkulungwane eziyi-1, okungaholela kulokho okweqile:
- Ungqimba oluvikelayo lwengxenye ye-auto luzoqala ukuhwamuka ngemva kokuncibilika ngokushesha.
- Ama-vapors ayakwazi ukungena ensimbi yomzimba, imiphumela enjalo izophazamisa ukwakheka kwezinto.
- Intuthu yokushisela eyeqile izothinta nakanjani ikhwalithi yelunga.
Ngemva kokwenza ukupheka ingxenye yomshini uwedwa, udinga ukukhumbula ukuthi le nqubo ihilela ukwanda kobuthi, okungalimaza impilo yomuntu.
Ukugawula umzimba wemoto
Ngaphandle kokungena komoya okunamandla nokukhiqizayo, umsebenzi akufanele uqalwe, futhi umoya akufanele ukhishwe kuphela endaweni yokukhwabanisa, kodwa kulo lonke igumbi.
Izinhlobo zokushisela insimbi
Ngaphambi kokushisela umzimba nge-galvanizing, i-coating ephezulu iyasuswa; lolu ungqimba lususwa kalula ngesenzo somshini ensimbi. Ehlome nganoma yimaphi ama-abrasives aqinile, kuzokwazi ukufeza imiphumela emihle futhi uqhubeke nokukhetha indlela yokusebenza inqubo, phakathi kwabo kuyathandwa:
- I-Semi-automatic.
- I-Inverter.
- Ukushisela umzimba ngesishisi segesi.
Uma ukusebenza ngemoto kuhilela ukusetshenziswa kwama-electrode, khona-ke amasampula omkhiqizo ajwayelekile ngeke asebenze, kuyadingeka ukuthenga amakhophi nge-rutile coating, kanye ne-alloy-carbon alloy - ANO-4, MP-3 noma OZS-4.
Welding Semiautomatic
Abanikazi abaningi bemishini bakhetha ukupheka izimoto ngale ndlela, ngoba i-galvanized seam ingaphezulu, iyunifomu futhi iyunifomu, ikhwalithi isezingeni eliphezulu.
Ukushisela umzimba kunezici eziningana, futhi amathuba okusha ayancipha. Kuzokwazi ukwenza ama-manipulations phambi kwe-voltage engaphansi kuka-220V, lokhu kusizwa ucingo olukhethekile kanye nezithasiselo zokuxhuma izingxenye zama-galvanized endaweni ngaphandle komkhathi wegesi ovikelayo.
Inverter welding
Lapho ukhetha le ndlela, kuzodingeka upheke i-galvanizing usebenzisa i-reverse polarity current, i-arc ivutha ngokuqinile, futhi i-electrode ishisa kuze kufike ezingeni lokushisa elifunayo ngemizuzwana embalwa nje.
Yini welding ukupheka umzimba imoto
Lapho wenza inqubo ngocingo, ukunyakaza kufanele kube bushelelezi ngangokunokwenzeka, ngaphandle kwama-jerks, ngaphandle kwalokho ubuso obunama-galvanized buyolimala. Uma usebenzisa ama-electrode, udinga ukukhumbula ukuthi ukuze unciphise amathuba okushisa ngengxenye yomshini, uzodinga ukukhetha kahle umthambeko wengxenye yamathuluzi.
Spot welding
Ukuze usebenzise lolu hlelo, kubalulekile ukukhetha izithasiselo ezifanele ze-zinc, umkhuba ubonisa ukuthi imiphumela emihle ingafinyelelwa ngezinto eziqukethe ithusi ngokuhlanganiswa ne-silicon, kanye ne-aluminium noma i-manganese. Izinto zibhalwe kanje: CuSi3, CuAl8, CuSi2Mn.
Amandla okugcina amalunga ensimbi azoxhomeka kuphela ngesilinganiso sezingxenye. Amasampula omkhiqizo wezingxenye ezintathu asiza ukwenza umthungo wezimoto ngamandla angeziwe, okwenza lezi zengezo zifaneleke kakhulu ukulungiswa kwezindawo zezingxenye zezimoto.
