I-Mutant Injection Molding Screw

Lesi sikulufu sokubumba umjovo we-mutant senziwe ngensimbi engu-38CrMoAla. Izinto ezingavuthiwe zibalulekile ekusebenzeni ngezikulufu, futhi sikhetha insimbi enamandla amakhulu nengagugi kubakhiqizi bensimbi abadumile baseShayina abahlangabezana nezindinganiso zikazwelonke (GB/T 3077).

Isikulufu sokubumba umjovo oguquguqukayo se-Nanhaiya sinesigaba sokuminyanisa esifushane, ngokuvamile esibalela cishe u-5% kuya ku-15% wesamba sobude bezikulufu. Kukhona indawo yokuminyanisa ehlukile phakathi kwesigaba sokuphakelayo nesemitha, lapho ukujula kwegroove ngesikulufu kuba kuncane kakhulu. Ukuguqulwa kwamandla ngesikhathi seplastiki kunamandla. Lapho ipulasitiki ingena esigabeni sokucindezela kusukela esigabeni sokuphakelayo, ingaphansi kwamandla aphezulu okucindezela kanye ne-shear ngesikhathi esifushane, ihlanganisa ngokushesha futhi ifake ipulasitiki.

Imiphongolo yesikulufu yokubumba yomjovo ka-Nanhaiya eguquguqukayo yenze i-R&D eminingi kanye nentuthuko futhi manje isihlanganiswe emigqeni yokukhiqiza yabakhiqizi abahlukahlukene, kuzuzwe ukusebenza kwesimanjemanje. Sinikeza iwaranti yeminyaka engu-1-2, kuye ngesilinganiso esithile sokwengezwa kwempahla. Imiphongolo ye-Nanhaiya ingena kunqubo ye-nitriding, enogqinsi oluwu-0.8~2m olujiyile lwe-nickel-tungsten alloy eshiselwe ezindaweni ezithandwa kakhulu. Lokhu kwandisa ubulukhuni bobuso bomgqomo yi-HRC55~62, kukhulisa ukumelana nokugqoka izikhathi ezingu-2-3.

Isici Futhi Isicelo

Idizayini yesikulufu sokubumba yomjovo oguquguqukayo ka-Nanhaiya ihlanganisa isigaba sokuminyanisa esibalela kuphela u-5% -15% wengqikithi yobude besikulufu. Kusukela ku-groove ejulile esigabeni sokuphakela kuya emgodini ongashoni ekupheleni kwesigaba sokucindezela, ukujula kushintsha ngokuzumayo, kungabikho indawo yokuguquka ebushelelezi, okwenza isakhiwo "sokucindezela okungazelelwe". Ingxenye yokondla ine-groove ejulile, eyenzelwe ukugcina inani elikhulu lezinto eziqinile; ingxenye yokulinganisa ine-groove engajulile, eklanyelwe ukwenza i-homogenize ukuncibilika. Lezi zingxenye ezimbili zixhunywe ngokuqondile ngesigaba esifushane sokucindezela. Lesi sigaba sokuminyanisa esifushane singaphansi kokucindezelwa okuqinile nokugunda ngebanga elifushane kakhulu, kuphazamise ngokushesha ukwakheka kwekristalu yamapulasitiki acwebile futhi kuzuze u-15% -30% ophezulu wokusebenza kahle kwepulasitiki kunesikulufu sokushintsha kancane kancane.  Amathayela e-resin awuhlobo olusha lwempahla yokwakha engasindi, engangeni manzi, evikela ukushisa, futhi ekwazi ukumelana nokugqwala. Zisetshenziswa kabanzi emkhakheni wokwakha futhi zingasetshenziselwa ukufulela, izinto zodonga, izinto zokuhlobisa, ama-awnings, nama-sunshades.

Ngenxa yesilinganiso sokuncibilika esisheshayo sesikulufu sokubumba umjovo owehlayo, ukuncibilika kokuqala kungase kube nokungalingani okuncane kwezinga lokushisa, okudinga ukulungiselelwa okwengeziwe komthelela we-homogenization ngokulungisa ingcindezi yangemuva nesivinini esigabeni semitha. Izikulufu zokubumba umjovo osuka phansi zilungele i-low-viscosity, amapulasitiki ekristalu anephuzu elincibilikayo elicacile, njenge-polyethylene(PE), i-polypropylene(PP), inayiloni (PA), i-polyoxymethylene (POM), kanye ne-fluoroplastics (PTFE).

Imininingwane Yomkhiqizo

Ukushisa okuthuthukisiwe, ukunemba kwemishini, nezinqubo ze-nitriding ziqinisekisa ukusebenza okuphelele kwezingxenye ezibalulekile.

Izindawo ezisengozini ye-screw kanye nomgqomo ziqiniswa nge-nickel-tungsten alloy layer, ezifinyelela ungqimba oluwugqinsi ongu-0.8-2.0mm futhi kuthuthukisa kakhulu ukumelana nokugqokwa.
