Ngophuhliso olukhawulezayo lweshishini lentsimbi, ukuze kuphuculwe izinga lemveliso yentsimbi, kuphuculwe izinga lokusetyenziswa kunye nokusebenza kakuhle kwemveliso yelitye lokusila, kwaye kuncitshiswe inani lokuvalwa kwesixhobo.ilitye lokusila, carbidemuyagularolsaAmakhonkco e-nd avele njengoko amaxesha efuna, kwaye asetyenziswa ngokubanzi kwi-high-speed wire rod rolling.inkqubo.
Ngeentsuku zokuqala, abantu babesebenzisa inkqubo yokusila ukucubungula i-carbide enesamenteumqulu wokusilas, kodwa ukusebenza kakuhle kokugaya kwakuphantsi kakhulu, okwachaphazela ukusebenza kwemveliso.Ekugqibeleni, isixhobo esinokuguqulwa endaweni yokugaya siphuhliswa, kwaye ukuguqulwa kusetyenziselwa ukubuyisela inkqubo yokugaya, ephucula kakhulu ukuveliswa kwemveliso yee-carbide rolls kunye nokunciphisa iindleko zokuvelisa.
Kwinkqubo yokuguqula i-carbide enesamenteumqulu wokusilas, ubunzima besixhobo ngokwawo kufuneka bube phezulu kunobunzima bomsebenzi oza kuqhutyelwa phambili.Ke ngoko, izixhobo zangoku zokusika izixhobo zokuguqula imiqulu ye-carbide enesamente ubukhulu becala bubunzima obuphezulu, obungangeni kubushushu obuphezulu obungeyontsimbi yokubopha i-cubic boron nitride kunye nedayimane.umamkeli.
Iindlela zokusetyenzwa kweCarbide roll kunye nemithetho yokukhetha izixhobo:
1. Jonga ubulukhuni: Carbide rolwe wI-ith ubulukhuni obungaphantsi kwe-HRA90 inokukhetha izinto ze-HLCBN okanye izinto ze-BNK30 zokujika kunye nezibonelelo ezinkulu, kwaye ukuguqula i-carbide rolls kunye nezibonelelo ezinkulu akuyi kuphula okanye kutshise isixhobo.Xa ubunzima be-carbide roll ye-cemented bukhulu kune-HRA90, uluhlu lokucubungula lwesixhobo se-cubic boron nitride lugqithisiwe.Ngokubanzi, isixhobo sedayimane se-CDW025 okanye ivili lokusila ledayimani elibotshwe ngentlaka lisetyenziselwa ukucola.Ngokubanzi, okukhona ukuqina kokuqina, kokukhona izinto ziya kuba brittle.Xa i-carbide ene-cemented inqunywe, i-cut cut iya kuba "i-slagging okanye i-chipping", eya kubangela ukuba i-workpiece ikhutshwe.Ke ngoko, kulumke ngakumbi ukusika izinto ezinobunzima obuphezulu.Yenza i-chamfering kwangaphambili, okanye usebenzise ulungiso oluchanekileyo lwangaphambili.Shiya isibonelelo sokusila esicolekileyo ukuze uphephe.
2. Jonga isibonelelo somatshini kunye nendlela yokucubungula: ukuba umphezulu wangaphandle okanye i-groove engaphezulu kwe-R3 yemoto icutshungulwa, kwaye isibonelelo sikhulu, ngokuqhelekileyo sebenzisa izinto ze-HLCBN okanye izinto ze-BNK30 zokucoca ngokukrakra, uze usebenzise ivili lokugaya. ukugaya (i-resin bond diamond).Ivili lokusila lokusila lesangqa sangaphandle okanye inqwelomoya, i-groove groove kunye nezinye izakhi zokusila ngokubanzi zisebenzisa i-electroplating okanye i-metal bond diamond yokusila ivili);kwisibonelelo somatshini omncinci, mhlawumbi sebenzisa ivili lokusila ngokusila ngokuthe ngqo, okanye usebenzise isixhobo sedayimane sokwenza iprofayili (ezifana nenkqubo ye-chamfering kunye nenkqubo ye-grooving, unokukhetha izixhobo zedayimani ezilungiselelwe);ngokuqhelekileyo, ukusika endaweni yokugaya kunokuphucula ukusebenza kakuhle, kwaye indlela yokusika i-carbide chips kulula ukuyibuyisela;ngenxa yokuba ukulungelelaniswa kokwenza ivili lokusila kufuna umjikelo Okanye i-mold iyadingeka, kodwa ukulungelelaniswa okungaqhelekanga kwesixhobo sokubumba ngokukhawuleza, ngoko ke indlela yokusika ilungele ngakumbi ekuphuculeni umjikelezo wemveliso.
3. Xa urhubuluza igroove yomqulu, iCDW025 diamond engraving kunye ne-milling cutter (ekwaziwa ngokuba yi-flying cutter, rotary cutter) isetyenziswa.
4. Imiqulu ihlukaniswe yaba yimveliso entsha kunye nokugaya.Ezi ndlela zingentla azifanelekanga kuphela ukubhekisela xa kuveliswa imiqulu emitsha kwiifektri ze-carbide roll ze-cemented, kodwa zingasetyenziselwa ukugaya i-carbide rolls kwi-mills yensimbi.
Xa machining carbide ngesamenteumqulu wokusilas, isixhobo sinokugqithiswa.Into ebizwa ngokuba yi-passivation treatment kukusombulula i-defect ye-micro-notch ye-edge yesixhobo emva kokulola, ukunciphisa okanye ukuphelisa ixabiso lomphetho, kunye nokufezekisa ukuguquguquka nokugudiswa.Injongo ebukhali eyomeleleyo kwaye ixesha elide.Nangona kunjalo, unyango lwe-passivation alufanele lube lukhulu kakhulu, kuba indawo yokudibanisa yomgca wokusika isixhobo iba mkhulu emva kokugqithisa, kwaye ukuchasana kokusika kuyanda.
