Ukudizayina kanye Nokusetshenziswa Kwedivayisi Yokushintsha Ngokushesha Izikhonkwane Ku-Surface ye-HPGR Roller

Amagama Abalulekile: HPGR; ubuso be-roller enezingqimba; idivayisi yokufaka esikhundleni se-stud; iphuzu lamandla; iphuzu lokucindezeleka; Ukuhlolwa kwe-Brazing;

Ukuze kuxazululwe ubunzima bokushintsha izikhonkwane ebusweni berola ye-HPGR, kwaklanywa idivayisi yokushintsha ngokushesha izikhonkwane, futhi kwethulwa indlela yokushintsha izikhonkwane. Idivayisi ibonakala ngokusebenza okulula, ukusetshenziswa okuphindaphindiwe, ubude besikhathi obufushane bokushintshwa, kanye nempilo ende yesevisi. Inganciphisa izindleko zokulungisa nokulungisa imishini nesikhathi, futhi ivikele ngempumelelo umkhono we-roller. Ukwehlisa izinga lokugqoka nokwelula isikhathi sempilo yesevisi.

Ngenxa yokuthi i-stud ifakwe emgodini we-stud kusetshenziswa i-gap fit ngokusebenzisa i-binder, umkhono we-stud othambile uzokhubazeka ngemva kokukhishwa kwesikhashana ngemva kokusetshenziswa, futhi ingxenye yomkhono we-roller ephukile inqunyelwe, futhi ezinye izikhonkwane. phuka ngaphakathi komkhono we-roller. Ngenxa yokuthi awekho amandla okuqaqa i-stud ephukile, kunzima kakhulu ukufaka esikhundleni se-stud ephukile. Ngisho noma i-ejenti yokubopha ihluleka ngokushisa, i-stud kusenzima ukuyikhipha. Ngakho-ke, kubaluleke kakhulu ukuthuthukisa idivayisi yokushintsha ngokushesha ye-roller face studs ukuze welule impilo yobuso be-roller.

Izimiso zokushintsha izikhonkwane:

Izimbobo ze-stud ne-stud ziyaqiniswa futhi zilungiswe ngokunamathela. Njengoba i-adhesive izohluleka ngemva kokushisa ekushiseni okuthile, i-adhesive ingakhutshazwa ngokushisa i-stud bese i-stud eyonakalisiwe ikhishwa ngokudweba. Kodwa-ke, ngenxa yokuthi ingxenye esele ye-stud ivame ukungcwatshwa emgodini we-stud lapho iphukile, kunzima ukuthwala amandla, ngakho-ke kuyadingeka ukushisela iphuzu lokucindezeleka kuma-studs asele ngokushisela.

Ukuhlolwa kokushisela:

Enkambweni yokuthatha isipikili esiphukile, kuyadingeka ukushisela i-stud kanye nedivaysi yokuguqula izipikili kanye namandla athile. Ngenxa yokuthi i-stud iyi-carbide ene-cemented, kunzima ukuhlanganisa nezinto zokushisela, ngakho-ke ukukhetha indlela efanele yokushisela kanye nezinto zokushisela kuba yisihluthulelo sokudonsa izigxobo. Ukuze unqobe inkinga yokucindezelwa kokushisela ngesikhathi sokushintshwa kwe-stud, ukuhlolwa kokushisela kwezikhonkwane ze-carbide zikasimende kwenziwa nge-arc welding kanye ne-brazing ngokulandelanayo.

Ukuhlolwa kwe-Brazing:

Ukuhlolwa kwe-stress point welding kwenziwa nge-brazing, futhi izinto eziyisisekelo kwakuyibha yensimbi evamile. Ngemuva kokushisela, akukho ukuqhekeka ku-stud futhi isisekelo sokushisela isisekelo siqine kakhulu (bheka Umfanekiso 1), ngakho-ke, kufanelekile ukusebenzisa indlela yokubopha ukushisela iphuzu lokucindezeleka futhi uxhume i-stud kanye nedivaysi yokushintsha izinzipho. .

Ukuze uxazulule ubunzima bokushintsha i-silver face stud yomshini wokugaya we-high-pressure, leli phepha likunikeza idivayisi yokushintsha esheshayo ye-roller face stud yomshini wokugaya i-roller high-pressure.

Njengoba kuboniswe kuMfanekiso 2, idivayisi iqukethe isikulufu sokuxhuma, i-nati, iwasha eliyisicaba, nepayipi lensimbi. Ingxenye eyodwa yesikulufu sokuxhuma ifakwe intambo, futhi ububanzi obujwayelekile kufanele bube bukhulu kunobubanzi be-stud, ukugwema ukuphazamiseka kwepayipi lensimbi lapho ukhipha i-stud. Omunye umkhawulo awucushiwe, futhi ububanzi buncane kune-stud, ekulungele ukushisela okulandelayo. I-nati ijikeleziswa ohlangothini lwentambo futhi ifakwe nge-washer eyisicaba. Lapho i-stud ephukile nesikulufu somthofu kushiselwa ndawonye, ​​inadi lisetshenziselwa ukugoqa isikulufu sokuhola esixhumayo futhi linikeze i-stud i-axial tension ebushelelezi; Ipayipi lensimbi limbozwe ohlangothini olungenantambo, futhi isikulufu sokuxhuma sivele obala.

Isilingo:

Njengoba kukhonjisiwe kuMdwebo 3, umqulu olahliwe we-stud extruding wasetshenziselwa ukwenza ukuhlolwa. Ukuphela kwentambo yomshini wokushintsha izipikili kwakushiselwe ku-stud endaweni ye-roll, futhi i-stud ingasuswa ngempumelelo ngokuphendula inati ngesikrufu.

Uma unentshisekelo ku-CARBIDE STUDS futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwekhasi.
