Ukulungiswa kwe-rubber extruder screw
1. I-screw ephothiweyo kufuneka ithathelwe ingqalelo ngokomlinganiselo wangaphakathi wangaphakathi we-barrel, kwaye ukuphambuka kwangaphandle kwedayimitha ye-screw entsha kufuneka kunikwe ngokuhambelana nokukhutshwa okuqhelekileyo kunye ne-barrel.
2. Emva kokuba umphezulu wentambo kunye nobubanzi obuncitshisiweyo be-screw egugileyo iphathwa, i-alloy-resistant-resistant alloy is sprayed thermally, kwaye emva koko iphantsi ukuya kubukhulu.Le ndlela ilungiswa ngokubanzi kwaye ilungiswe ngumzi-mveliso ochwephesha wokutshiza, kwaye iindleko ziphantsi.
3. I-overlay ye-welding wear-resistant alloy kwinxalenye yentambo yesikrufu esigugileyo.Ngokweqondo lokunxitywa kwesijirufu, ukuwelda okuphezu komhlaba yi-1 ~ 2mm ubukhulu, kwaye emva koko isikrufu siyagutywa kwaye silungiswe ngokobukhulu.Le alloy-resistant-resistant alloy yenziwe ngezinto ezifana ne-C, Cr, Vi, Co, W kunye ne-B, eyandisa ukunyanzeliswa kokunxiba kunye nokuxhatshazwa kwe-corrosion of screw.Izityalo zokujonga phezulu zineendleko eziphezulu zolu hlobo lokusetyenzwa, kwaye azifane zisetyenziswe ngaphandle kweemfuno ezikhethekileyo zezikrufu.
4. I-hard chrome plating ingasetyenziselwa ukulungisa isikrufu.I-Chromium iphinde ibe yintsimbi engagugiyo kunye ne-corrosion-resistant, kodwa umaleko onzima we-chrome kulula ukuwa.
Ukulungiswa kwe-rubber extruder barrel
Ubunzima bangaphakathi bombhobho buphezulu kune-screw, kwaye umonakalo wayo usemva kwexesha le-screw.Ukuchithwa kombhobho kukunyuka kobubanzi bangaphakathi ngenxa yokugqoka kunye nokukrazula ngexesha.Nantsi indlela yokuyilungisa:
1. Ukuba ububanzi bombhobho buyanda ngenxa yokugqoka, ukuba kusekho i-nitriding layer, umngxuma wangaphakathi we-barrel unokubhoreka ngokuthe ngqo, umhlaba ube yi-diameter entsha, kwaye ke isikrufu esitsha sinokulungiswa ngokwale nto. ububanzi.
2. I-diameter yangaphakathi ye-barrel yenziwe ngoomatshini kwaye inqunywe ukuze iphinde ifakwe i-alloy, ubukhulu buphakathi kwe-1 ~ 2mm, kwaye emva koko igqibe ubungakanani.
3. Kwiimeko eziqhelekileyo, icandelo le-homogenization lombhobho linxiba ngokukhawuleza.Eli candelo (ubude be-5 ~ 7D) bunokucutshungulwa ngokukruqula, kwaye emva koko lixhotyiswe nge-nitrided alloy steel bushing.Ububanzi bomngxuma wangaphakathi bubhekiselele kububanzi be-screw.Ukukhutshwa okuqhelekileyo kokufanelekileyo kuyacutshungulwa kwaye kulungiswe.
Kugxininiswa apha ukuba iinxalenye ezimbini ezibalulekileyo ze-screw kunye ne-barrel, enye yintonga ene-threaded threaded, kwaye enye ingumngxuma onobubanzi obuncinci kunye nobude.Iinkqubo zabo zokucoca kunye nokushisa zinzima ngakumbi, kwaye kunzima ukuqinisekisa ukuchaneka..Ngoko ke, nokuba kulungiswe okanye kutshintshe iinxalenye ezintsha emva kokunxiba kwezi zimbini kufuneka kuhlalutywe ngokubanzi ngokwembono yezoqoqosho.Ukuba iindleko zokulungisa ziphantsi kuneendleko zokutshintsha isikrufu esitsha, kugqitywe ukuba silungise.Oku akuthethi ukuba lolona khetho lufanelekileyo.Ukuthelekiswa phakathi kweendleko zokulungisa kunye neendleko zokubuyisela yinto enye kuphela.Ukongezelela, kuxhomekeke kumlinganiselo weendleko zokulungisa kunye nexesha lokusebenzisa i-screw emva kokulungiswa kweendleko zokutshintshwa kunye nexesha lokusebenzisa i-screw ehlaziyiweyo.Kuqoqosho ukwamkela iskimu esinomlinganiselo omncinci, olona lukhetho oluchanekileyo.
4. Izixhobo zokwenza isikrufu kunye nomphanda
Ukwenziwa kwezikrufu kunye nemigqomo.Okwangoku, izinto ezisetyenziswa ngokuqhelekileyo e-China ziyi-45, 40Cr kunye ne-38CrMoAlA.
