Gusana reberi ya extruder screw
1. Imigozi ihindagurika igomba gutekerezwa ukurikije diameter yimbere yimbere ya barriel, kandi gutandukana kwinyuma ya diameter yo hanze ya screw nshya bigomba gutangwa ukurikije ibisanzwe bisanzwe hamwe na barriel.
2. Nyuma yubuso bwurudodo hamwe na diameter yagabanutse ya screw yambuwe ivuwe, imiti irwanya kwambara iraterwa ubushyuhe, hanyuma ikamanuka kugeza mubunini.Ubu buryo muri rusange butunganywa kandi bugasanwa nuruganda rutera umwuga, kandi igiciro ni gito.
3. Gupfundikanya gusudira kwambara bidashobora kwihanganira igice cyurudodo rwimyenda yambarwa.Ukurikije urugero rwimyenda ya screw, gusudira hejuru yuburebure bwa 1 ~ 2mm, hanyuma umugozi ukaba hasi kandi bigakorwa mubunini.Iyi miti idashobora kwangirika igizwe nibikoresho nka C, Cr, Vi, Co, W na B, byongera imbaraga zo kwambara no kurwanya ruswa.Ibihingwa byabigize umwuga bifite ibiciro byinshi kuri ubu buryo bwo gutunganya, kandi muri rusange ntibikoreshwa cyane usibye ibisabwa byihariye kuri screw.
4. Isahani ikomeye ya chrome irashobora kandi gukoreshwa mugusana umugozi.Chromium nayo ni ibyuma birwanya kwambara kandi birwanya ruswa, ariko urwego rukomeye rwa chrome rworoshye kugwa.
Gusana reberi extruder barrel
Ubuso bwimbere bwimbere ya barriel burenze ubw'umugozi, kandi ibyangiritse bitinze kurenza ibya screw.Gukuraho ingunguru niyongera rya diameter y'imbere kubera kwambara no kurira mugihe.Dore uko wabikemura:
1. Niba diameter ya barrale yiyongereye kubera kwambara, niba hakiri urwego runaka rwa nitriding, umwobo wimbere wikigega urashobora kurambirwa bitaziguye, hasi kugeza kuri diametre nshya, hanyuma harashobora gutegurwa umugozi mushya ukurikije ibi diameter.
2. Diameter y'imbere ya barrale irakorwa kandi igatunganywa kugirango yongere guterera, umubyimba uri hagati ya 1 ~ 2mm, hanyuma ukarangiza kugeza mubunini.
3. Mubihe bisanzwe, igice cya homogenisation ya barrale yambara vuba.Iki gice (uburebure bwa 5 ~ 7D) kirashobora kugabanywa no kurambirana, hanyuma bigashyirwa hamwe na nitrided alloy ibyuma.Diameter yumwobo wimbere yerekeza kuri diameter ya screw.Ibisanzwe bikwiye gutunganywa no gutegurwa.
Hano hashimangiwe ko ibice bibiri byingenzi bya screw na barriel, kimwe ni inkoni yoroheje, naho ikindi ni umwobo ufite diameter ntoya kandi ndende.Gutunganya no gutunganya ubushyuhe biragoye, kandi biragoye kwemeza neza..Kubwibyo, niba gusana cyangwa gusimbuza ibice bishya nyuma yo kwambara ibi bice byombi bigomba gusesengurwa byimazeyo duhereye kubukungu.Niba igiciro cyo gusana kiri munsi yikiguzi cyo gusimbuza umugozi mushya, hafashwe icyemezo cyo kugisana.Ibi ntabwo byanze bikunze guhitamo neza.Kugereranya hagati yikiguzi cyo gusana nigiciro cyo gusimburwa nikintu kimwe gusa.Mubyongeyeho, biterwa nikigereranyo cyikiguzi cyo gusana nigihe cyo gukoresha screw nyuma yo gusanwa nigiciro cyo gusimburwa nigihe cyo gukoresha screw ivuguruye.Nibyiza gufata gahunda ifite igipimo gito, aricyo guhitamo neza.
4. Ibikoresho byo gukora screw na barriel
Gukora imigozi na barriel.Kugeza ubu, ibikoresho bikunze gukoreshwa mu Bushinwa ni 45, 40Cr na 38CrMoAlA.
