Indlela yokulungisa umonakalo we-rubber extruder screw kanye nomgqomo

Ukulungiswa kwesikulufu se-rubber extruder

1. Isikulufu esisontekile kufanele sicatshangelwe ngokuvumelana nobubanzi bangempela bangaphakathi bomgqomo, futhi ukuchezuka kobubanzi bangaphandle kwesikulufu esisha kufanele kunikezwe ngokuvumelana nokuvunyelwa okujwayelekile ngomgqomo.

2. Ngemuva kokuthi indawo yentambo enobubanzi obuncishisiwe besikulufu esigugile selashwe, i-alloy engagugi ifafazwa nge-thermal, bese igaywa ngosayizi.Le ndlela ngokuvamile icutshungulwa futhi ilungiswe imboni yokufafaza echwepheshile, futhi izindleko ziphansi.

3. Ingxubevange yokushisela engagugi engxenyeni yentambo yesikulufu esigugile.Ngokwezinga lokuguga kwesikulufu, ukushisela okungaphezulu kuwugqinsi ongu-1~2mm, bese isikulufu siyagaywa futhi sicutshungulwe ngosayizi.Le alloy engagugi yakhiwe ngezinto ezifana no-C, Cr, Vi, Co, W no-B, okwandisa ukumelana nokuguga nokumelana nokugqwala kwesikulufu.Izitshalo ezisezingeni eliphezulu zinezindleko eziphezulu zalolu hlobo lokucubungula, futhi ngokuvamile azivamile ukusetshenziswa ngaphandle kwezidingo ezikhethekile zezikulufu.

4. Ukufakwa kwe-hard chrome nakho kungasetshenziswa ukulungisa isikulufu.I-Chromium futhi iyinsimbi engagugi futhi imelana nokugqwala, kodwa ungqimba lwe-chrome eqinile kulula ukuwa.

Ukulungiswa komgqomo we-raber extruder

Ukuqina kwangaphakathi komgqomo kuphakeme kunokwesikulufu, futhi umonakalo waso udlula owesikulufu.Ukuchithwa komgqomo ukwanda kobubanzi bangaphakathi ngenxa yokuguga nokudabuka ngokuhamba kwesikhathi.Nansi indlela yokuyilungisa:

1. Uma ububanzi bomphongolo bukhula ngenxa yokugqoka, uma kusekhona ungqimba oluthile lwe-nitriding, imbobo yangaphakathi yombhobho ingaba nesithukuthezi ngokuqondile, iphansi ibe ububanzi obusha, bese isikulufa esisha singalungiswa ngokusho kwalokhu. ububanzi.

2. Ububanzi bangaphakathi bomgqomo bulungiswa ngomshini futhi busikwe ukuze kusakazwe kabusha ingxubevange, ubukhulu buphakathi kuka-1 ~ 2mm, bese buqeda ngosayizi.

3. Ngaphansi kwezimo ezijwayelekile, isigaba se-homogenization somphongolo sigqoka ngokushesha.Lesi sigaba (ubude obungu-5 ~ 7D) singasikwa ngokubhora, bese sihlonywa nge-nitrided alloy steel bushing.Ububanzi bomgodi ongaphakathi bubhekisela kububanzi besikulufu.Ukwelashwa okujwayelekile kuyacutshungulwa futhi kulungiselelwe.

Kuyagcizelelwa lapha ukuthi izingxenye ezimbili ezibalulekile ze-screw kanye nomgqomo, enye iyinduku encane enezintambo, kanti enye iyimbobo enobubanzi obuncane futhi bude.Izinqubo zabo zokukhiqiza imishini nokushisa ziyinkimbinkimbi, futhi kunzima ukuqinisekisa ukunemba..Ngakho-ke, noma ukulungisa noma ukushintsha izingxenye ezintsha ngemva kokugqoka kwalezi zingxenye ezimbili kufanele kuhlaziywe ngokugcwele ngokombono wezomnotho.Uma izindleko zokulungisa ziphansi kunezindleko zokushintsha isikulufa esisha, kunqunywa ukusilungisa.Lokhu akukona ngempela ukukhetha okufanele.Ukuqhathaniswa phakathi kwezindleko zokulungisa kanye nezindleko zokushintsha kuyisici esisodwa kuphela.Ngaphezu kwalokho, kuncike esilinganisweni sezindleko zokulungisa kanye nesikhathi sokusebenzisa isikulufu ngemva kokulungiswa kwezindleko zokushintsha kanye nesikhathi sokusebenzisa isikulufu esibuyekeziwe.Kungokonga ukwamukela uhlelo olunesilinganiso esincane, okuyisinqumo esifanele.

4. Izinto zokwakha isikulufu nemigqomo

Ukwenziwa kwezikulufu nemiphongolo.Njengamanje, izinto ezisetshenziswa kakhulu e-China yi-45, 40Cr kanye ne-38CrMoAlA.
