Insimbi engaphekiwe isetshenziswa kakhulu ezimbonini zezimoto nezasekhaya ngenxa yokumelana nokugqwala okuhle kakhulu. Kodwa-ke, ukumbozwa kwe-zinc kunsimbi enezinsimbi kunezinselele eziyingqayizivele ngesikhathi sokushisela. Abaningi bayazibuza: ingabe umshini wokushisela ungashisela insimbi enama-galvanized? Impendulo ithi yebo! Imishini yokushisela ayikwazi ukushisela insimbi kuphela, kodwa futhi ingabhekana ngokuphumelelayo nezinkinga ezivamile zokushisela ezifana ne-porosity ne-spttering, okubenza baye{2}}kokusebenza kokushisela insimbi.
Izinselelo Zokushisela Insimbi Eyisithako
Inselele eyinhloko ekushiseleni insimbi ethathiwe isekuhlanganiseni kwayo kwe-zinc. I-Zinc inephuzu lokubilisa eliphansi uma kuqhathaniswa (cishe ama-degree angama-907), okubangela ukuthi ihwamuke ngesikhathi sokushisela. Lokhu kuhwamuka kungaholela ekwakhekeni kwamaphakethe egesi (i-porosity), ama-welds abuthakathaka, kanye nomphumela wokushisela omubi ngokuphelele. Izindlela zokushisela zendabuko zivame ukubhekana nalokhu, okuholela ekwandeni kwamaphutha kanye nokuqina kwamalunga.
Nokho, ukumelana Welding imishini, kuhlanganiseUmshini wokushisela isitoreji samandla , zenzelwe ukunqoba lezi zinkinga. Le mishini ihlinzeka ngokulawula okunembile phezu kwamapharamitha wokushisela, okubavumela ukuthi babhekane nezinselele ezilethwa insimbi yama-galvanized ngempumelelo.
Umshini Wokushisela Uyixazulula Kanjani Inkinga Yensimbi Ephekiwe?
Imishini yokushisela eqinile isebenzisa-inqubo yezinyathelo ezintathu-yokushisa kuqala, ukushisela, nokufudumeza{2}}ukuphatha isendlalelo se-zinc ku-galvanized steel. Nansi indlela esebenza ngayo:
- Isiteji Sokushisa: Umshini wokushisela usebenzisa i-current encane ukuze ushise ngobumnene isendlalelo se-zinc, okubangela ukuba sihwamuke ngaphandle kokudala ukwakheka kwegesi ngokweqile noma i-splattering. Lesi sinyathelo sinciphisa ingozi ye-porosity.
- Isiteji Esiyinhloko Sokushisela: Umshini wokushisela bese usebenzisa i-current ephakeme ukuze uqhube i-weld eyinhloko. Phakathi nalesi sigaba, ungqimba lwezinc olusele luncane, luqinisekisa ukushisela okuqinile, okuhlanzekile.
- Isiteji Sokuthula: Ekugcineni, umshini usebenzisa i-current low ngesikhathi sesiteji sokushisa ukuze ukhulule noma yikuphi ukucindezeleka okudalwe ngesikhathi senqubo yokushisela. Lesi sinyathelo sisiza ukuthuthukisa ikhwalithi yonke namandla we-weld.
Ngokuphatha ngokucophelela ukugeleza kwamanje kanye nesikhathi sokushisela, umshini wokushisela we-Energy storage iqinisekisa ukuthi ungqimba lwe-zinc luphathwa ngendlela efanele, okuvumela ukushisela okuhlanzekile nokuthembekile kunsimbi.
Izinzuzo Eziyinhloko Zemishini Yokushisela Ye-Resistance Welding Steel
Imishini yokushisela i-Resistance welding ilungele ukushisela insimbi enama-galvanized ngenxa yezici zayo ezithuthukile namandla okulawula:
- Ukulawula Kwamanje Okunembile: I-welding current ingalungiswa ngaphakathi kwebanga elibanzi ukuze ivumelane nogqinsi nezici zensimbi ebilisiwe. Isibonelo, uma ushisela insimbi engu-1.0mm, umshini wokushisela ngokuvamile usebenzisa i-preheat current engu-150A ngama-5ms, kulandelwa i-welding current enkulu engu-280A ye-10ms. Lokhu kuqinisekisa i-weld evikelekile futhi ehlanzekile, enokusabalalisa okuncane kanye ne-porosity.
- Digital Control Systems: Imishini eminingi yesimanje yokushisela ifika ifakwe izinhlelo zokulawula idijithali ezilungisa ngokuzenzakalelayo amapharamitha asuselwa kubukhulu bezinto ezibonakalayo kanye nohlobo. Lokhu kuqeda isidingo sokushintshwa kwesandla njalo, okwenza inqubo yokushisela isebenze kahle futhi ingaguquki.
- Ikhwalithi Ye-Weld Ethuthukisiwe: Ngokuqeda izinselele ezihambisana nongqimba lwe-zinc, imishini yokushisela iqinisekisa ukuthi ama-welds aqinile, abushelelezi, futhi abukeka kahle. Lokhu kuzenza zifanelekele ikakhulukazi izimboni ezidinga{1}}amashisela ekhwalithi ephezulu, njengokukhiqiza izimoto kanye nokukhiqiza izinto zikagesi.
- Ukusebenza Kwengeziwe: Ukunemba okunikezwa nguUmshini wokushisela isitoreji samandlainika amandla ukushisela okusheshayo nangempumelelo, okungasiza ukunciphisa izikhathi zokukhiqiza nokwandisa okukhiphayo. Lokhu kubaluleke kakhulu ezindaweni zokukhiqiza{1}eziphezulu lapho isivinini nekhwalithi kokubili kubalulekile.
Amathiphu Okusebenza Wokushisela Insimbi Eyisithako
Ukuze uthole imiphumela engcono kakhulu uma usebenzisa umshini wokushisela wensimbi yensimbi, kunezici ezimbalwa ezibalulekile okufanele uzikhumbule:
- Hlanza Indawo: Ngaphambi kokushisela, kubalulekile ukuqinisekisa ukuthi ingaphezulu lensimbi ethathiwe lihlanzekile. Noma yikuphi uwoyela, ukugqwala, noma ukungcola kungaphazamisa inqubo yokushisela futhi kuholele emalungeni abuthakathaka. Sebenzisa i-ejenti yokuhlanza efanelekile ukuze ususe noma yikuphi ukungcola.
- Lungisa I-Electrode Pressure: Ingcindezi esetshenziswa ama-electrode welding kumele ilungiswe ngokucophelela. Ukucindezela okukhulu kungabangela ukuhwamuka ngokweqile kongqimba lwezinc, okuholela ekulimaleni. Ngokuphambene, ukucindezela okunganele kungaholela ekushiseleleni okubuthakathaka. Ingcindezi ekahle iqinisekisa ukuthintana okufanele phakathi kwama-electrode nensimbi ngaphandle kokubangela ukuhwamuka kwe-zinc ngokweqile.
- Isondlo Esivamile: Ukugcinwa njalo komshini wokushisela ukumelana, ikakhulukazi ama-electrode, kubalulekile ekugcineni ukusebenza kahle. Qinisekisa ukuthi amathiphu e-electrode ahlanzekile futhi awanawo ukwakhiwa ukuze ugweme imiphumela yokushisela engahambisani.
Isiphetho:
Isishiseli sendawo yokugcina izinto asikwazi nje ukushisela insimbi ethathiwe, kodwa futhi sinikeza isisombululo esisebenzayo ezinseleleni ezibangelwa ungqimba lwezinc. Ngokulawula kwamanje okunembile kanye nekhono lokulawula ukuhwamuka kwe-zinc, imishini yokushisela iqinisekisa ukushisela okuqinile,{1}}kwekhwalithi ephezulu. Ukuguquguquka kwazo, kuhlanganiswe nezinhlelo zokulawula ezithuthukisiwe, kuzenza zibe yinketho ekhethwayo ezimbonini ezidinga ukushiselwa okuthembekile nokusebenza kahle kwezinto ezenziwe nguthayela.
Ukwazi kahle ukusetshenziswa kwemishini yokushisela ukumelana nensimbi kubalulekile kubakhiqizi abafuna ukuthuthukisa ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza. Ukutshala imali ku-aUmshini wokushisela isitoreji samandlakusho ukutshala imali kukhambi elithembekile,{0}}eliphezulu lokusebenza lokushisela insimbi yamagalani, ukuqinisekisa ukuthi izinqubo zakho zokukhiqiza zihlala zishelela futhi zibiza{1}}zisebenza ngempumelelo.
