Umqondo kanye nokwenziwa kwe-polishing
Kungani kudingeka senze ukucubungula okungaphezulu kwezingxenye zemishini?
Inqubo yokwelashwa engaphezulu izohluka ngezinhloso ezihlukile.
1 izinhloso ezintathu zokucutshungulwa kwezingxenye zemishini:
1.1 Indlela yokucubungula engaphezulu yokuthola ukunemba kwengxenye
Ezingxenyeni ezinezidingo ezifanayo, izidingo zokunemba (kufaka phakathi ukunemba okunobukhulu, ukunemba kwesimo kanye nokunemba kwesikhundla) kuvame ukuphakama, futhi ukunemba nokuqina komhlaba kuhlobene. Ukuthola ukunemba, ubulukhuni obuhambisanayo kumele bufezwe. Isibonelo: Ukunemba IT6 ngokuvamile kudinga ukuqina okuhambisanayo ra0.8.
[Izindlela ezejwayelekile zemishini]:
- Ukuguquka noma ukugaya
- Isicefe esihle
- Ukugaya okuhle
- Gonqiweyo
Izindlela zokucubungula ezingaphezulu komhlaba zokuthola izakhiwo zomshini we-surface
1.2.1 ukuthola ukumelana kokugqoka
[Izindlela ezijwayelekile]
- Ukugaya ngemuva kokuqina noma ukuguqula / ukuqeda (nitriding)
- Ukugaya nokupholizwa ngemuva kokugcwala kanzima kwe-chrome
1.2.2 Ukuthola isimo esihle sokuxineka
[Izindlela ezijwayelekile]
- Ukushintshanisa nokugaya
- Ukwelashwa kokushisa komhlaba nokugaya
- Ukugoqa komhlaba noma ukudubula kwe-peening kulandelwa ukugaya okuhle
1.3 Izindlela Zokucubungula Ukuthola Izakhiwo Zamakhemikhali Engaphezulu
[Izindlela ezijwayelekile]
- I-Electroplating kanye nokupholisha
2 ubuchwepheshe be-polishing yensimbi engu-2
2.1 Ukubaluleka kuyingxenye ebalulekile yensimu yobuchwepheshe bezobuchwepheshe nobunjiniyela, futhi kusetshenziswa kabanzi ezinhlakeni zokukhiqiza izimboni, ikakhulukazi embonini yezokwenziwa kwama-electroplatial, ukunamathela, anodizing kanye nezinqubo ezahlukahlukene zokwelashwa.
2.2 Kungani amapharamitha okuqala angaphezulu komhlaba kanye nemingcele yethonya elitholakele lomsebenzi wokusebenza libaluleke kangaka?Ngoba zingamaphuzu wokuqalisa futhi ahlosiwe womsebenzi wokupholisa, onquma ukuthi ungayikhetha kanjani uhlobo lomshini wokupholisa, kanye nenani lamakhanda okugaya, uhlobo lwezinto ezibonakalayo, izindleko, kanye nokusebenza kahle okudingekayo emshinini wokuphola.
2.3 izigaba zokugaya & zokupholisisa kanye ne-trajectories
Izigaba ezine ezivamile zegonqiweyona-Polishing]: Ngokwe-roughness yokuqala nesokugcina ye-RA amanani we-workpiepe, ukugaya kwama-coarse - ukugaya okuhle - ukugaya okuhle - ukugaya okuhle - polishing. Ukuhlukumezeka okubalwa kusuka ekuhlanganiseni kuya kulungile. Ithuluzi lokugaya nokusebenza kwendawo yokusebenza kufanele kuhlanzwe njalo lapho zishintshiwe.
2.3.1 Ithuluzi lokugaya linzima, umphumela wokusika nokukhishwa okuphezulu mkhulu, kanti usayizi nokuqina kunezinguquko ezisobala.
2.3.2 I-Mechanical Polishing iyinqubo ethambile yokusika kunokugaya. Ithuluzi lokuphola lenziwe ngezinto ezithambile, ezinganciphisa kuphela ubulukhuni kepha azikwazi ukuguqula ukunemba kosayizi nokwakheka. Ubulukhuni bungafinyelela ngaphansi kuka-0.4μm.
2.4 Imiqondo emithathu emincane yokwelashwa kokuqeda komhlaba: ukugaya, ukudonswa, nokuqeda
2.4.1 Umqondo wokugaya okwenziwe ngomshini nokupholizwa
Yize zombili ukugaya imishini yokugaya kanye ne-mechanic polishing kunganciphisa ubulukhuni bendawo, kukhona umehluko:
- 【I-Mechan Polishing】: Kubandakanya ukubekezelelana kobukhulu, ukubekezelela ukwakheka nokubekezelela isikhundla. Kumele iqinisekise ukubekezelelana okubucayi, ukubekezelela ukwakheka kanye nokubekezelela isikhundla komhlabaphansi ngenkathi kunciphisa ubulukhuni.
- I-Mechan Polishing: Ihlukile ekupholizweni. Kuthuthukisa kuphela ukuqeda okungaphezulu, kepha ukubekezelelana akunakuqinisekiswa ngokuthembekile. Ukukhanya kwalo kuphakeme futhi kukhanya kunokupholisha. Indlela ejwayelekile yokudonswa kwemishini ukugaya.
2.4.2 [Ukuqedela ukucubungula] kuyinqubo yokugaya nokuphambanisa (okufushaniswa njengokugaya nokuphoqelela) kwenziwa emsebenzini ngemuva kwemishini emihle, ngaphandle kokususa ungqimba oluncane kakhulu, ngaphandle kwenhloso enkulu yokunciphisa ubulukhuni bendawo, ukwandisa isicwebezelisi sayo.
Ukunemba nokuqina kwengxenye yengxenye kunethonya elikhulu empilweni yakhe nangekhwalithi yalo. Ungqimba oluwohloka olusele yi-EDM nemifantu emincane eshiywe ngokugaya izothinta impilo yenkonzo yezingxenye.
Inqubo yokuqeda inesibonelelo esincane semishini futhi isetshenziselwa ikakhulukazi ukuthuthukisa ikhwalithi ephezulu. Inani elincane lisetshenziselwa ukuthuthukisa ukunemba kwemishini (njengokunemba okunobukhulu kanye nokunemba kwesimo), kepha akunakusetshenziselwa ukwenza ngcono ukunemba kwesikhundla.
Ukuqedwa yinqubo yokusika okuncane kanye nokukhipha indawo yokusebenza ngenhlamvu ngenhlamvu emihle. Ingaphezulu licutshungulwa ngokulinganayo, amandla okusika nokushisa ukushisa mancane kakhulu, futhi ikhwalithi ephezulu kakhulu ingatholakala. ③ Ukuqeda kuyinqubo yokucubungula ama-micro-ukucubungula futhi ngeke kulungise iphutha elikhulu lendawo. Ukucubungula okuhle kumele kwenziwe ngaphambi kokucutshungulwa.
Umongo we-Metal Surface Polishing ukucubungula okuncane okukhethiwe okuncane.
3. Izindlela ezivuthiwe zamanje izindlela ezivuthiwe: 3.1 Ukudonswa Kwemishini, 3.2 Ukupholisha Kwamakhemikhali, 3.3 I-Electrolytic Polishing, 3.4 I-Ultrasonic Polishing, 3.5 Polishing Yokugaya, 3.6 Ukupholisha Kagculi,
3.1 I-Mechanical Polishing
I-Mechanic Polishing indlela yokuphola ethembele ekusikeni nasekuguqukeni kwepulasitiki kobuso bezinto ezibonakalayo ukususa ama-protor abushelelezi ukuthola indawo ebushelelezi.
Usebenzisa lobu buchwepheshe, i-mehendi polishing ingafinyelela ubulukhuni bendawo ye-ra0.008μm, okuphezulu kakhulu phakathi kwezindlela ezahlukahlukene zokuphamba. Le ndlela ivame ukusetshenziswa ku-amalensi yamalensi.
3.2 Ukupholishelwa Kwamakhemikhali
I-Chemical Polishing ukwenza izingxenye ze-microscopic convex zobuso bezinto ezibonakalayo zihlaziswe ngokukhethekile ezikhundleni zamakhemikhali ngaphezulu kwezingxenye zemihlabe, ukuze uthole indawo ebushelelezi. Izinzuzo eziphambili zale ndlela ukuthi ayidingi imishini eyinkimbinkimbi, ingakwazi ukuPheka imisebenzi yokusebenza ngezimo eziyinkimbinkimbi, ingaphola ama-arvice amaningi ngasikhathi sinye, futhi isebenza kahle kakhulu. Udaba oluyinhloko lokupholisha amakhemikhali ukulungiswa koketshezi lokupholisha. Ubudlova obungaphezulu obutholwe yi-Chemical Polishing ngokuvamile amashumi ambalwa we-μm.
3.3 I-electrolytic polishing
I-electrolytic polishing, eyaziwa nangokuthi i-electrochemical polishing, inciphisa ama-protorthion amancane ebusweni balokho okuqukethwe ukuze kubushelelezi.
Uma kuqhathaniswa nokuphoqelelwa kwamakhemikhali, umphumela wokuphendula kweKathode kungaqedwa futhi umphumela ungcono. Inqubo ye-Electrochemical Polishing ihlukaniswe izinyathelo ezimbili:
.
.
3.4 I-Ultrasonic Polishing
I-Workiepe ibekwe ekumisweni okuxakayo futhi ibekwe enkambu ye-ultrasonic. Ukuhlukumezeka kuwumhlaba futhi kudwetshwe endaweni yokusebenza nge-oscillation yegagasi le-ultrasonic. I-Ultrasonic Maching ine-macroscopic force encane futhi ngeke idale ukuguqulwa kwe-workpiece, kepha i-toorting inzima ukuyenza futhi ifake.
I-Ultrasonic Maching ingahlanganiswa nezindlela zamakhemikhali noma ze-electrochemical. Ngokwesisekelo sokugqwala kwesixazululo kanye ne-electrolysis, ukudlidliza kwe-ultrasonic kusetshenziselwa ukugqugquzela isixazululo ukuhlukanisa imikhiqizo encibilikisiwe endaweni yokwenziwa komhlaba futhi yenza i-corrosion noma i-electrolyte eduze komfaniswano wendawo; Umphumela we-Cavitation wamagagasi e-ultrasonic ku-ketshezi ungavimba futhi inqubo yokugqwala futhi wenze lula ukugqamisa komhlaba.
3.5 I-Fluid Polishing
I-Fluid Polishing ithembela ngoketshezi oluhamba ngejubane eliphezulu kanye nezinhlayiya ezixakile ukuxubha indawo yokusebenza ukuze kufinyelelwe inhloso yokupholisha.
Izindlela ezisetshenziswayo ezivame ukusetshenziswa zifaka phakathi: Ukucutshungulwa kwe-jet abrasive, ukucubungula i-Jet ye-Liquid, ukugaya okunamandla, njll.
3.6 ukugaya kwamandla kazibuthe nokupholisa
Ukugaya kwamandla kazibuthe kusetshenziswa ama-magnetic abrasives ukwakha amabhulashi abizayo ngaphansi kwesenzo sensimu kazibuthe ukugaya umsebenzi wokwenza umsebenzi.
Le ndlela inokusebenza kahle okuphezulu, ikhwalithi enhle, ukulawulwa okulula kwezimo zokucubungula, kanye nezimo ezinhle zokusebenza. Nge-abrasives efanelekile, ubulukhuni obungaphezulu bungafinyelela ra0.1μm.
Ngalesi sihloko, ngikholwa ukuthi uzoba nokuqonda okungcono kokupholisha. Izinhlobo ezahlukene zemishini yokuphambanisa zizonquma umphumela, ukusebenza kahle, izindleko nezinye izinkomba zokuthola imigomo ehlukile yokuposa umsebenzi.
Hlobo luni lomshini wokupholisa inkampani noma amakhasimende akho okudingayo akufanele kufaniswe kuphela ngokuya nge-WorkPhisi uqobo, kodwa futhi kususelwa ekufunweni kwemakethe komsebenzisi, isimo sezezimali, ukuthuthukiswa kwebhizinisi nakwezinye izinto.
Vele, kunendlela elula elula yokubhekana nalokhu. Sicela uxhumane nabasebenzi bethu bangaphambi kokuthengisa ukukusiza.
