Iindlela zokunciphisa i-Crack ye-Carbide Cutting Tool

1. Lawula indlela yokufudumeza ukunciphisa ukuveliswa kwe-crack.

Xa ubushushu bokushisa bulawulwa malunga ne-30-50 ° C ngaphezu kwendawo yokunyibilika kwe-solder, indawo yokunyibilika ye-solder ekhethiweyo kufuneka ibe ngaphantsi kwe-melting point ye-arbor nge-60 ° C. Ngethuba lokutshisa, ilangatye kufuneka lifudumale ngokulinganayo ukusuka ezantsi ukuya phezulu kwaye lifudumeze ngokukhawuleza ukutshisa. Ngoko ke, i-groove kunye ne-carbide blade iyafuneka. Umphezulu wokubhobhoza uhambelana, ukufudumala kwendawo kuya kwenza umehluko weqondo lokushisa phakathi kwe-blade ngokwayo okanye i-blade kunye nomphathi wesixhobo esikhulu, kwaye uxinzelelo lwe-thermal luya kubangela ukuba umgca we-blade uqhekeke. Idangatye kufuneka lihanjiswe emva naphambili umva naphambili ukuya kubushushu, ukuze kuthintelwe ukufudumeza kwendawo kunye nokuqhekeka okubangelwa kukuxinana kobushushu.

2. Ifuthe lemilo ye-sipe ekubunjweni kokuqhekeka yaziwa kakuhle.

Ubume be-groove ye-knife ayihambelani ne-brazing surface ye-knife shank okanye inomahluko omkhulu, okwenza i-groove evaliweyo okanye i-semi-closed shape, ekulula ukubangela ukugqithiswa kwe-brazing kunye ne-welding layer. Ngenxa yokungahambelani kwesantya sokunciphisa emva kokwandiswa kwe-thermal, kulula kwakhona kwi-carbide blade brazes ukuba ibangele uxinzelelo olugqithisileyo kunye nokwenza iintanda. Ummandla we-brazing surface kufuneka uncitshiswe ngokusemandleni phantsi kwemeko yeemfuno zamandla e-weld eyanelisayo yokusetyenziswa.

3. Pholisa ngobuchule.

Ukupholisa okukhawulezayo ngexesha okanye emva kokubhobhoza kunye nokuphelelwa ngamanzi emzimbeni okungahambi kakuhle kuya kubangela ngokulula ukuba incam ye-carbide blade igqabhuke kwaye iqhekeke. Ngoko ke, i-solder iyadingeka ukuba ibe neepropati ezilungileyo zokuchithwa kwamanzi. Emva kokutshiza, akufuneki kufakwe emanzini ukupholisa ngokukhawuleza. Emva kokupholisa kancinane esantini, njl.

4. Nika ingqalelo kwimpembelelo yeziphene kwindawo ephantsi ye-sipe kwi-crack.

Umphezulu wokudibanisa phakathi kwe-blade kunye ne-kerf ayigudi. Ukuba kukho imingxuma yesikhumba esimnyama kunye nezizathu zokungalingani kwendawo, ukubethelwa akukwazi ukwenza i-flat joint, eya kubangela ukusabalalisa okungalinganiyo kwe-solder, engachaphazeli nje kuphela amandla e-weld kodwa ibangela uxinzelelo loxinzelelo, kwaye kulula ukubangela i-blade ukuphuka, ngoko i-blade kufuneka igaye indawo yokudibanisa, kunye ne-welding surface ye-blade groove kufuneka ihlambuluke. Ukuba inxalenye yenkxaso yomphathi wesixhobo ikhulu kakhulu okanye inxalenye yenkxaso yomphathi wesixhobo ibuthathaka, isixhobo siya kulawulwa ngamandla obunzima ngexesha lenkqubo yokuqhafaza kunye nokuphuka kuya kwenzeka.

5.Nika ingqalelo kwisiphumo sokufudumala kwesibini kwe-blade ekubunjweni kokuqhekeka.

Emva kokuba i-blade igxininiswe, isinyithi sobhedu sokutshiza asiyizalisi ngokupheleleyo isithuba, kwaye ngamanye amaxesha kuya kubakho i-welding ebonakalayo, kwaye ezinye iimela ziya kuwa kwi-blade ngexesha lenkqubo yokuphuma eziko, ngoko kufuneka ukuba shushu kabini. Nangona kunjalo, i-cobalt binder itshiswa kakhulu, kwaye iinkozo ze-WC zikhula, ezinokukhokelela ngokuthe ngqo ekuqhekekeni kwe-blade.

I-carbide enesamente inobunzima obuphezulu kunye nokuqina. Ukuba inkqubo yokuqhafaza ingenankathalo, iya kuchithwa ngenxa yokuqhekeka. Qonda iingongoma zokuqwalaselwa xa ubhengeza izixhobo zokusika i-tungsten carbide ukuphepha iintanda ze-welding.
