I-Mutant Isikrufu sokuBumba isikrufu

Esi sikrufu sokubumba inaliti ye-mutant senziwe ngentsimbi eyi-38CrMoAla. Imathiriyeli ekrwada ibalulekile ekujikeni ukusebenza, kwaye sikhetha amandla aphezulu kunye nentsimbi engagugiyo kubavelisi bentsimbi abaziwayo baseTshayina abahlangabezana nemigangatho yesizwe (GB/T 3077).

Isikrufu sokubumba inaliti ye-Nanhaiya ye-mutant inecandelo elifutshane locinezelo, ngokuqhelekileyo libalelwa malunga ne-5% ukuya kwi-15% yobude bobude bezikrufu. Kukho indawo yocinezelo eyahlukileyo phakathi kwefidi kunye namacandelo okulinganisa, apho ubunzulu be-screw groove buthi ngequbuliso bube nzulu. Ukuguqulwa kwamandla ngexesha leplastiki kunamandla. Xa iplastiki ingena kwicandelo lokunyanzeliswa kwecandelo lokutya, liphantsi koxinzelelo oluphezulu kunye nemikhosi yokucheba ngexesha elifutshane, idibanisa ngokukhawuleza kunye neplastiki yeplastiki.

I-Nanhaiya's mutant mutant molding screw barrels ziye zadlula kwi-R&D ezininzi kunye nophuculo kwaye ngoku zidityaniswe kwimigca yemveliso eyahlukeneyo yabenzi, ukuphumeza ukusebenza komgangatho. Sinikezela ngewaranti yeminyaka eyi-1-2, kuxhomekeke kumlinganiselo othile wokongezwa kwezinto. Imigqomo ye-Nanhaiya ingena kwinkqubo ye-nitriding, kunye ne-0.8 ~ 2m engqindilili ye-nickel-tungsten alloy alloy spray-welded kwiindawo ezithandwa kakhulu. Oku kwandisa ukuqina komphezulu we-barrel yi-HRC55 ~ 62, ukunyusa ukuxhathisa ukunxiba ngamaxesha angama-2-3.

Uphawu kunye nesicelo

I-Nanhaiya's mutant's mutant molding screw design iquka icandelo locinezelo elibalelwa kwi-5% -15% kuphela yobude bobude bezikrufu. Ukususela kwi-groove enzulu kwicandelo lokutya ukuya kwi-groove enzulu ekupheleni kwecandelo lokunyanzeliswa, ubunzulu buguquka ngokukhawuleza, kungekho ndawo yokutshintsha okugudileyo, ukudala "ukunyanzeliswa ngokukhawuleza". Icandelo lokutya line-groove enzulu, eyenzelwe ukugcina ubuninzi bezinto eziqinileyo; icandelo lokulinganisa linomsele ongekho nzulu, olungiselelwe ukunyibilika kwi-homogenize. Amacandelo amabini adityaniswe ngokuthe ngqo licandelo elifutshane lokucinezela. Eli candelo lifutshane loxinzelelo lixhomekeke kwizinto eziqinileyo ukunyanzeliswa okukhulu kunye nokucheba kumgama omfutshane kakhulu, ukuphazamisa ngokukhawuleza ukwakheka kwekristale yeeplastiki zekristale kunye nokufezekisa i-15% -30% ephezulu ye-plasticizing esebenzayo kune-screw-conducting screw.  Iithayile zeresin luhlobo olutsha lwemathiriyeli yokwakha ekhaphukhaphu, ingangeni manzi, ikhusela ubushushu, kwaye imelana nomhlwa. Zisetyenziswa kakhulu kwintsimi yokwakha kwaye zingasetyenziselwa ukuphahla, izinto zodonga, izinto zokuhombisa, i-awnings, kunye ne-sunshades.

Ngenxa yesantya sokunyibilika ngokukhawuleza kwe-screw-down injection molding screw, i-melt yokuqala inokuba nokungalingani okuncinci kweqondo lokushisa, ifuna ukuphuculwa ngakumbi kwe-homogenization effect ngokulungelelanisa uxinzelelo lwangasemva kunye nesantya kwicandelo lemitha. Izikrufu zokubumba i-step-down injection zifanelekile kwi-low-viscosity, iiplastiki zekristalline ezinendawo yokunyibilika ecacileyo, njenge-polyethylene (PE), i-polypropylene (PP), inayiloni (PA), i-polyoxymethylene (POM), kunye ne-fluoroplastics (PTFE).

Iinkcukacha zeMveliso

Ubushushu obuphezulu, ukuchaneka komatshini, kunye neenkqubo ze-nitriding ziqinisekisa ukusebenza okubanzi kwamacandelo aphambili.

Iindawo ezinobungozi ze-screw kunye ne-barrel ziqiniswa nge-nickel-tungsten alloy layer, ukufikelela kwi-0.8-2.0mm umaleko obunzima kunye nokuphucula kakhulu ukuxhathisa ukunxiba.
