Ukusuka kwimbono yesakhiwo seiincakuba zesarha yedayimani, i-matrix kunye ne-serration zizinto ezimbini eziphambili ezenza i-blade ngokwayo.Phakathi kwabo, i-substrate imathiriyeli inquma ukuqina kweidayimani isarha blade, ngelixa umgangatho wee-serrations unquma ukukhululeka kokusetyenziswa kwe-saw blade.
Niniidayimani isarha bladeabavelisi bavelisaiincakuba zesarha yedayimani, i-matrix kunye ne-serration zikhona njengamacandelo amabini azimeleyo.
I-matrix kunye ne-saw blade zihamba ngendlela yazo kwaye azihambelani, ngoko azikwazi ukwenza into epheleleyoidayimani isarha blade.Nangona kunjalo, abaninziidayimani isarha bladeabavelisi, ukwenzela ukuba badibanise i-saw blade kunye ne-matrix, iindlela eziphambili zezi: i-brazing kunye ne-laser welding.
Ukuqhayisa, iinkokeli ezininzi zoshishino ezibandakanyekayo kwiiprofayili ze-aluminium kunye nokulungiswa kwamatye ziya kuqhelana kakhulu nazo.Ngenxa yokuba ukubrawuza ngoku kuyindlela esetyenziswa ngokuqhelekileyo yokuwelda amazinyo xa abavelisi be-alloy saw blade besenza ii-saw blade.
Okwangoku, njengenkqubo ye-sawtooth ekhulile kakhulu, i-brazing isetyenziselwa ukuwelda iintloko zokusika idayimani.Nangona kunjalo, xa kuthelekiswa ne-laser welding, ibrazing isenazo iintsilelo ezithile.
Kubaiincakuba zesarha yedayimaninge-diameter encinci kwaye isetyenziselwa ukusika okomileyo, indlela ye-Laser beam welding amazinyo yamkelwa ngokubanzi.Kubaiincakuba zesarha yedayimaniabasebenzisa iindlela zokusika ezimanzi ukusika iprofayili yamatye okanye i-aluminiyam, i-brazing isetyenziselwa ukudibanisa izinyo.
Kwezi ndlela zimbini zedayimani eqhelekileyo yabona izinyo lokuwelda, abantu abaninzi baya kucinga ukuba umgangatho we-laser welding uphezulu kunowokugawula, ngoko kububulumko ukukhethaidayimani isarha bladenge laser welding indlela.
Le ngcamango eneneni ingumntwana kakhulu.Nokuba i-brazing okanye i-laser welding, yenye yezinto ezininzi ezichaphazela umphumo wokusika we-saw blade.
Kunokuthiwa ukukhethaiincakuba zesarha yedayimanikuphela ngokukhetha iindlela ze-welding azikwazi ukufikelela kwisiphumo esilindelekileyo sokusika.Ukukhetha i-brazing okanye i-laser welding, kububulumko ukukhetha aidayimani isarha bladezilungele wena emva koqwalaselo olubanzi.
Ukususela kwiimpawu zeendlela ezimbini ze-welding, ngenxa yefuthe elibi lomatshini phakathi kweidayimani isarha bladekunye neprofayili ngexesha lenkqubo yokusika, ukushisa kwe-saw blade ngokwayo kwanda ngokukhawuleza.
Phakathi kwabo, ukuba umsebenzi wokupholisa we-saw blade awenziwanga kakuhle.Ke, indawo ecandiweyo yi "focal point" ethwala ubushushu.
Kweli nqanaba, phantsi kweemeko ezinjalo, inani elincinci leiincakuba zesarha yedayimaniusebenzisa itekhnoloji yebrazing inokuba namava okuthambisa kwiindawo zabo zokuwelda.Ngethuba lokujikeleza kwesantya esiphezulu kunye nemisebenzi yokusika eyomileyo, yonke intloko yokusika inokukhupha kwi-substrate.
Phantsi kweemeko ezinjalo, iingenelo zeiincakuba zesarha yedayimaningelaser welding saw amazinyo agxininiswe.Phakathi kwazo, ukugoba amandla e-laser weld anokufikelela kwi-1800MPa.
Amandla okugoba komthungo we-welding weidayimani isarha bladeusebenzisa indlela yokubrawuza yi-350MPa ~ 600MPa kuphela.Xa kuthelekiswa nokubrawuza, ukuwelda ngelaser kunciphisa kakhulu ukuba nokwenzeka kwesixhobo sokuwa.
Kuba ezi zimbini ziqhelekileyoidayimani isarha bladeiinkqubo welding, asinakuthembela omnye ukuqinisekisa umgangatho yonke isarha blade.
Kwiiprofayili ezininzi ze-aluminium kunye namashishini okucubungula amatye, ukwenzela ukuba kuqinisekiswe umphumo wokusika i-saw blade, ukongeza ekuhloleni indlela ye-welding ye-saw blade xa uzisaiincakuba zesarha yedayimani, isitshixo sokuqinisekisa isiphumo sokusika kunye nokwandisa ubomi benkonzo yeidayimani isarha bladekukwenza umsebenzi omhle ekupholiseni nasekusileni i-saw blade ngexesha lokusetyenziswa.
Phakathi kwabo, ngenxa yokupholisa kweiincakuba zesarha yedayimani, esona sisombululo sivuthiweyo kwishishini kukusebenzisa inkqubo yokuthambisa encinci.Ulwelo olukhethekileyo lokusika lufafazwe kwi-saw blade ngendlela ye-atomization ekusetyenzisweni kwe-0.05ml ngesekhondi ngesixhobo sokuthambisa esincinci, kwaye ke ubushushu obuqokelelwe kwi-saw blade buthathwa.
Ngencakuba ye-aidayimani isarha blade, ukuba i-blade ingasetyenziselwa iminyaka embalwa eyongezelelweyo, ukugaya okugugileidayimani isarha bladeemva kokuba igugile iba sisisombululo esisebenzayo sokwandisa ubomi benkonzo ye-saw blade kunye nokunciphisa iqondo lokunxiba izinyo.
Kuzo zonke iinkqubo ze-20 + zokugaya, umgangatho wokugaya ubuye waphuculwa kakhulu, kunye nenye igugileidayimani isarha bladeukukwazi ukubuyisela ubuncinane i-80% yokusebenza kwayo kokusika emva kokusila.
Kakade ke, akukho zinto zingasentla kuphela ezinokuchaphazela umphumo wokusikaiincakuba zesarha yedayimani.Kodwa ukuvuselela ngokwenene igugileidayimani isarha blade, kufuneka sithathe amanyathelo angakumbi.
