Kwimigqomo yethu sitshiza ingxubevange eqinileyo isangqa esijikeleze indawo yokunxitywa kwebhore, izisa ubulukhuni bangaphakathi kwi-62 HRC. Umgca kulula ukuwuzoba:ifayibha yeglasi ukuya kuthi ga kwi-30% ihamba kakuhle kwiseti ye-nitrided 38CrMoAlA. Ngaphezulu kwe-30% yeglasi, ene-mineral filler okanye i-flame retardant, okanye kwi-resin e-corrosive, iya kwi-bimetallic. Indawo ene-nitrided yi-0.5–0.8 mm ediffusion layer, kwaye isihlunu esinzima sinqumla kuso ixesha elide phambi kokuba intsimbi engaphantsi igqitywe.
Umbuzo: Ngaba uyilo lwe-screw luchaphazela umgangatho wenxalenye yokubumba inaliti?
A: Ngokuthe ngqo, nangaphezulu kwezicwangciso ezininzi zenkqubo. Ijiyometri yesikruru imisela ukuba imathiriyeli inyibilika kangakanani na, ifana kangakanani na iqondo lobushushu lokunyibilika, umbala kunye nesihluzi sisasazeke kakuhle kangakanani, kunye nokuba ukudutyulwa kuhambelana kangakanani na. Ukunganyibiliki, imivimbo, i-splay, ukuthotywa, kunye nokwahluka kweedubulo zonke zibuyela emva kuyilo lwesikrufu okanye ukunxitywa kwe-screw ubuncinci rhoqo njengoko zilandela umva kwisilawuli. Xa isiphene sichasa zonke iinguqu zokumisela ozenzayo, ijometri okanye ukunxiba ngokuqhelekileyo sisizathu.
Q: Uthini umahluko phakathi kwesikrufu sokutofa kunye nesikrufu se-extrusion?
A: Isikrufu se-extrusion sijikeleza ngokuqhubekayo kwaye iipompo zinyibilika phambili ngaphandle kokumisa. Isikrufu sokutofa senza imisebenzi emibini: siyajikela ukwenza iplastikhi isitofu, emva koko siyeke ukujikeleza kwaye siqhubele phambili njengeplunger ukuyitofa. Eso senzo siphindaphindayo kungenxa yokuba izikrufu zenaliti ziphethe ikhonkco lokutshekisha kwincam, kwaye kutheni zibaleka umlinganiselo we-L/D omfutshane, oqhele ukuba yi-18:1 ukuya ku-25:1, kunezikrufu ze-extrusion. Isixhobo sikwahlala kumgqomo wenaliti phakathi kokudubula, okwenza ixesha lokuhlala kunye nobukhulu bokudubula bubaluleke kakhulu.
Umbuzo: Ngaba umenzi webhari yesikrufu angakopa isikrufu sam ngaphandle komzobo?
