Indlela yokulungisa umonakalo we-screw kunye ne-barrel ye-raber extruder

Ukulungiswa kwesikrufu se-raber extruder

1. Isikrufu esijijekileyo kufuneka siqwalaselwe ngokwesixa-mali sangaphakathi somgqomo, kwaye ukuphambuka kobubanzi bangaphandle besikrufu esitsha kufuneka kunikwe ngokwesithuba esiqhelekileyo somgqomo.

2. Emva kokuba umphezulu womsonto onobubanzi obuncitshisiweyo besikrufu esigugileyo ulungisiwe, i-alloy engagugiyo iyatshizwa ngobushushu, ize emva koko igutywe ngokobukhulu bayo. Le ndlela isetyenziswa ngokubanzi kwaye ilungiswe ngumzi-mveliso wobuchwephesha wokutshiza, kwaye ixabiso liphantsi kakhulu.

3. I-alloy enganyangekiyo yokuwelda egqunywe yi-overlay kwinxalenye yomsonto we-screw egugileyo. Ngokwezinga lokuguguleka kwe-screw, i-welding yokuwelda ibukhulu obuyi-1 ~ 2mm, kwaye emva koko i-screw iyacolwa kwaye icutshungulwe ngokobukhulu bayo. Le alloy enganyangekiyo yenziwe ngezinto ezifana ne-C, Cr, Vi, Co, W kunye ne-B, nto leyo eyandisa ukuxhathisa ukuguguleka kunye nokuxhathisa ukugqwala kwe-screw. Izityalo zokuwelda zobungcali zineendleko eziphezulu zolu hlobo lokucubungula, kwaye zihlala zingasetyenziswa ngaphandle kweemfuno ezizodwa zee-screw.

4. I-hard chrome plating ingasetyenziselwa ukulungisa isikrufu. I-Chromium ikwayintsimbi engagugiyo nengagqwaliyo, kodwa umaleko we-chrome oqinileyo kulula ukuwuwisa.

Ukulungiswa kwebharele yerabha ekhuphayo

Ubulukhuni bomphezulu wangaphakathi webhareli buphezulu kunobo beskrubu, kwaye umonakalo walo usemva koweskrubu. Ukukrazulwa kwebhareli kukwanda kobubanzi bangaphakathi ngenxa yokuguguleka ngokuhamba kwexesha. Nantsi indlela yokuyilungisa:

1. Ukuba ububanzi bomgqomo buyanda ngenxa yokuguguleka, ukuba kusekho umaleko othile we-nitriding, umngxuma ongaphakathi womgqomo unokugqojozwa ngqo, ucolwe ube bububanzi obutsha, uze emva koko kulungiswe isikrufu esitsha ngokwalo bubanzi.

2. Ububanzi bangaphakathi bombhobho buyacutshungulwa kwaye bulungiswe ukuze kuphinde kufakwe ingxubevange, ubukhulu buphakathi kwe-1 ~ 2mm, uze ugqibezele ngokobukhulu.

3. Kwiimeko eziqhelekileyo, icandelo le-homogenization lebharele liyaguga ngokukhawuleza. Eli candelo (ubude obuyi-5 ~ 7D) linokunqunyulwa ngokubhoboza, lize lixhotyiswe nge-nitrided alloy steel bushing. Ububanzi bomngxuma ongaphakathi bubhekisa kububanzi besikrufu. Ukususwa okuqhelekileyo kokulingana kuyacutshungulwa kwaye kulungiswe.

Apha kugxininiswa ukuba iindawo ezimbini ezibalulekileyo zesikrufu kunye nomgqomo, enye yintonga ebhityileyo enemisonto, kwaye enye ngumngxuma onobubanzi obuncinci nobude. Iinkqubo zazo zokulungisa nokulungisa ubushushu ziyinkimbinkimbi ngakumbi, kwaye kunzima ukuqinisekisa ukuchaneka. . Ke ngoko, nokuba kulungiswe okanye kutshintshwe iindawo ezintsha emva kokuguguleka kwezi ndawo zimbini kufuneka kuhlalutywe ngokupheleleyo ngokwembono yezoqoqosho. Ukuba iindleko zokulungisa ziphantsi kuneendleko zokutshintsha isikrufu esitsha, kugqitywa ukuba silungiswe. Oku akusoloko kuyikhetho elifanelekileyo. Uthelekiso phakathi kweendleko zokulungisa kunye neendleko zokutshintsha luphawu olunye kuphela. Ukongeza, kuxhomekeke kumlinganiselo weendleko zokulungisa kunye nexesha lokusebenzisa isikrufu emva kokulungiswa kwindleko yokutshintsha kunye nexesha lokusebenzisa isikrufu esihlaziyiweyo. Kungcono ukwamkela iskimu enomlinganiselo omncinci, olukhetho oluchanekileyo.

4. Izixhobo zokwenza izikrufu kunye neebhareli

Ukwenziwa kwezikrufu kunye neebhareli. Okwangoku, izixhobo ezisetyenziswa kakhulu eTshayina yi-45, 40Cr kunye ne-38CrMoAlA.
