Izindlela Zokunciphisa Ukuqhekeka Kwethuluzi Lokusika I-Carbide

1. Lawula indlela yokushisa ukuze unciphise ukukhiqizwa kwe-crack.

Uma izinga lokushisa lokubilisa lilawulwa cishe ngo-30-50 ° C ngaphezu kwendawo yokuncibilika ye-solder, indawo yokuncibilika ye-solder ekhethiwe kufanele ibe phansi kunephuzu lokuncibilika le-arbor ngo-60 ° C. Ngesikhathi sokubhula, ilangabi kufanele lishiswe ngokulinganayo ukusuka phansi ukuya phezulu futhi lishise kancane kancane ukuze libhuqe. Ngakho-ke, i-groove ne-carbide blade iyadingeka. Indawo yokubeka i-brazing iyahambisana, ukushisa okweqile kwendawo kuzokwenza umehluko wezinga lokushisa phakathi kwe-blade ngokwayo noma i-blade nesibambi samathuluzi sibe sikhudlwana, futhi ukucindezeleka okushisayo kuzobangela ukuqhekeka kwe-blade. Ilangabi kufanele lihanjiswe liye emuva naphambili ukuze lishise, ukuze kugwenywe ukushisa okweqile kwendawo kanye nokuqhekeka okubangelwa ukugcwala kokushisa.

2. Umthelela we-sipe shape ekubunjweni kokuqhekeka waziwa kahle.

Ukuma kwe-groove yommese akuhambisani ne-brazing surface ye-shank yommese noma kunomehluko omkhulu, okwenza umumo we-groove ovaliwe noma ovalwe kancane, okulula ukubangela ukuqina kwe-brazing ngokweqile kanye nongqimba lwe-welding ngokweqile. Ngenxa yezinga lokushwabana elingaguquki ngemva kokunwetshwa kokushisa, kulula futhi kumabraze e-carbide blade ukuze abangele ukucindezeleka ngokweqile futhi akhe imifantu. Indawo ye-brazing surface kufanele incishiswe ngangokunokwenzeka ngaphansi kwesimo sezidingo zamandla e-weld ezanelisayo ukuze zisetshenziswe.

3. Phola ngobuhlakani.

Ukupholisa okusheshayo ngesikhathi noma ngemva kokubhuqa kanye nokuphelelwa amanzi kahle kwamanzi okugeleza kuzokwenza kalula ukuthi ithiphu le-carbide blade liqhume futhi libhodloze. Ngakho-ke, i-solder iyadingeka ukuze ibe nezindawo ezinhle zokuqeda amanzi emzimbeni. Ngemuva kokubhula, akufanele ifakwe emanzini ukuze iphole ngokushesha. Ngemva kokupholisa kancane esihlabathini, njll., igcinwa cishe ku-300 ℃ amahora angaphezu kwangu-6 futhi ipholiswe ngesithando somlilo.

4. Naka umphumela wamaphutha endaweni engaphansi ye-sipe ekuqhekekeni.

Indawo yokuxhumana phakathi kwe-blade ne-kerf ayibushelelezi. Uma kunemigodi yesikhumba esimnyama kanye nezizathu zokungalingani kwendawo, i-brazing ayikwazi ukwakha i-joint flat, okuzobangela ukusabalalisa okungalingani kwe-solder, okungathinti kuphela amandla we-weld kodwa futhi kubangela ukugxila kokucindezeleka, futhi kulula ukuphuka kwe-blade, ngakho-ke i-blade kufanele igaye indawo yokuxhumana, futhi i-welding surface ye-blade groove kufanele ihlanzwe. Uma ingxenye yokusekela yesibambi samathuluzi inkulu kakhulu noma ingxenye yokusekela yesibambi sethuluzi ibuthakathaka, ithuluzi lizobhekana namandla aqinile phakathi nenqubo yokubhula futhi kuzophuka.

5.Naka umphumela wokushisa kwesibili kwe-blade ekubunjweni kokuqhekeka.

Ngemuva kokuthi i-blade iboshwe, insimbi yokugcwalisa i-copper ayigcwalisi ngokuphelele igebe, futhi ngezinye izikhathi kuyoba khona ukushisela okubonakalayo, futhi imimese ethile izowa phezu kwe-blade ngesikhathi sokuphuma esithandweni, ngakho-ke idinga ukukhishwa. ukushisisa kabili. Kodwa-ke, i-cobalt binder ishiswa kakhulu, futhi izinhlamvu ze-WC ziyakhula, ezingase ziholele ngokuqondile ekuqhekekeni kwe-blade.

I-carbide enosimende inokuqina okuphezulu nokuqina. Uma inqubo yokubhula inganaki, izochithwa ngenxa yokuqhekeka. Qonda amaphuzu okunaka lapho ubhula amathuluzi okusika i-tungsten carbide ukugwema imifantu yokushisela.
