Umahluko phakathi kwentsimbi ebrashiweyo nekhazimlisiweyo!
Ngokwetheknoloji, inkqubo yokudweba ucingo kukwenza iphethini yomhlaba oqhelekileyo kunye nofanayo kumphezulu womsebenzi.Iipateni zomzobo jikelele zezi: imigca emincinci kunye nezangqa.Inkqubo yokupholisa kukwenza umphezulu we-workpiece uphelele ngokupheleleyo, ngaphandle kweziphoso, kwaye ukhangeleka kakuhle kwaye uguquguquke, kunye nesibuko.
Ngokumalunga nokunyakaza, yintoni inkqubo yokudweba ucingo kwisixhobo yintshukumo ephindaphindiweyo, ngelixa inkqubo yokupholisa iyindlela yokuhamba eyenziwa kumatshini wokupholisa flat.Ezi zimbini zahlukile ngomgaqo kwaye zahlukile ekusebenzeni.
Kwimveliso, izixhobo zenkqubo yokuzoba ngocingo zisetyenziselwa umzobo wocingo, kwaye kukho iintlobo ezininzi zezixhobo zenkqubo yokupolisha ngokwemilo eyahlukeneyo yokuqhelana neemfuno ezahlukeneyo zokupholisha.
Ukuba i-workpiece ifuna ukuzotywa nokucocwa, yeyiphi inkqubo ekufuneka ilandelwe yile yangaphambili?
Ukususela kule meko, ukusuka kwisiphumo somzobo wocingo kunye nokupholisa kunyango lomphezulu, kunye nomgaqo-nkqubo wenkqubo, akunzima ukuba sidwebe: ukupolisha ngaphambili, umzobo wocingo emva.Kuphela emva kokuba umphezulu we-workpiece uphuculwe kwaye uhlanjululwe, umzobo wocingo unokuqhutyelwa, kuba ngale ndlela kuphela umphumo wokudweba ucingo uya kuba kuhle, kwaye imigca yokudweba ucingo iya kuba yinto efanayo.Ukupholisha kukuxukuxa kunye nokubeka isiseko.Ngelizwi, ukuba umzobo wocingo uphuculwe kuqala, kungekhona nje umphumo wokudweba ucingo olubi, kodwa imigca emihle yokuzoba intambo iya kugqitywa ngokupheleleyo ngediski yokusila ngexesha lokupholisa, ngoko akukho nto kuthiwa yimpembelelo yokudweba ucingo.
Izilumkiso zeshiti lentsimbi yomzobo wentsimbi engenasici
1. I-Brushed (i-frosted): Ngokuqhelekileyo, umgangatho we-surface yimigca ethe tye (ekwabizwa ngokuba yi-frosted) emva kokucutshungulwa ngokuxutywa komatshini kwi-surface yensimbi engenasici, kubandakanywa umzobo wocingo, kunye nemigca kunye ne-ripples.
Umgangatho womgangatho wokucutshungulwa: ubukhulu bokwakheka bufana kwaye bufana, ukuthungwa kwicala ngalinye lemveliso kuyindalo kwaye buhle ngokweemfuno zoyilo kunye nolwakhiwo, kunye nesikhundla sokugoba semveliso sivumelekile ukuba sibe nesiphithiphithi esincinci. ayichaphazeli inkangeleko.
- Inkqubo yokuzoba:
(1) Iinkozo ezenziwe ngeendidi ezahlukeneyo zesanti zahlukile.Ubukhulu bohlobo lwe-sandpaper, i-grains iyancipha, i-grains iyancipha.Ngokuchasene noko, i-sandpaper
Imodeli encinci kukuba, isanti iya kuba yingqimba, i-texture iya kuba nzulu.Ngoko ke, imodeli ye-sandpaper kufuneka iboniswe kumzobo wobunjineli.
(2) Umzobo wocingo uyalathiswa: kufuneka uboniswe kumzobo wobunjineli ukuba uthe tye okanye umzobo wocingo othe tye (omele iintolo ezimbini).
(3) Umzobo womzobo womsebenzi womzobo akufanele ube namalungu aphakanyisiweyo, ngaphandle koko iindawo eziphakanyisiweyo ziya kucandwa.
Qaphela: Ngokuqhelekileyo, emva kokudweba ucingo, i-electroplating, i-oxidation, njl.Njenge: intsimbi yokubeka, i-aluminium oxidation.Ngenxa yeziphene zomatshini wokudweba ucingo, xa kukho imingxuma emikhulu kwizinto ezincinci zokusebenza kunye nezixhobo zokusebenza, ukuyila i-jig yokudweba ucingo kufuneka kuthathelwe ingqalelo., ukuphepha umgangatho ombi we-workpiece emva kokudweba ucingo.
- Umsebenzi womatshini wokuzoba ngocingo kunye nezilumkiso
Ngaphambi kokudweba, umatshini wokudweba kufuneka ulungelelanise ukuphakama okufanelekileyo ngokobunzima bezinto eziphathekayo.
Isantya esicothayo sebhanti lokuhambisa, kokukhona sicotha ukusila, kwaye ngokuphambeneyo.Ukuba ubunzulu bokutya bukhulu kakhulu, umphezulu we-workpiece uya kutshiswa, ngoko ke umxhesho ngamnye akufanele ube mkhulu, kufuneka ube malunga ne-0.05mm.
Ukuba uxinzelelo lwe-cylinder yokucinezela luncinci kakhulu, i-workpiece ayiyi kunyanzeliswa ngokuqinileyo, kwaye i-workpiece iya kuphoswa ngaphandle ngamandla e-centrifugal ye-roller.Ukuba uxinzelelo luphezulu kakhulu, ukuxhathisa ukugaya kuya kwandiswa kwaye umphumo wokugaya uya kuchaphazeleka.Ububanzi bomzobo obusebenzayo bomatshini wokudweba ucingo aludluli i-600mm.Ukuba ulwalathiso lungaphantsi kwe-600mm, kufuneka ubeke ingqalelo kwindlela yokudweba, kuba isalathiso somzobo sisecaleni kwendlela yokutya.
Izilumkiso kwiphepha lentsimbi yokupholisha intsimbi
Ibakala eliqaqambileyo lentsimbi engatyiwayo emva kokupholishwa Ngokuphononongwa okubonakalayo, ukuqaqamba kobuso obukhazimlisiweyo bamacandelo buhlulwe ngokwamabakala ama-5:
Inqanaba 1: Kukho ifilimu ye-oxide emhlophe phezu komhlaba, akukho kukhanya;
Inqanaba lesi-2: Iqaqambile kancinane, ulwandlalo alunakubonwa ngokucacileyo;
Inqanaba lesi-3: Ukukhanya kubhetele, ulwandlalo lunokubonwa;
IBakala 4: Umphezulu ugqamile, kwaye ulwandlalo lunokubonwa ngokucacileyo (olulingana nomgangatho womphezulu we-electrochemical polishing);
Inqanaba lesi-5: Ukukhanya okufana nesipili.
Inkqubo jikelele yokupholisha ngoomatshini ngolu hlobo lulandelayo:
(1) Ukuphoswa rhabaxa
Emva kokugaya, i-EDM, ukugaya kunye nezinye iinkqubo, umphezulu unokupholiswa ngumatshini ojikelezayo wokupolisha indawo okanye umatshini wokugaya we-ultrasonic ngesantya esijikelezayo se-35 000-40 000 rpm.Indlela esetyenziswa ngokuqhelekileyo kukusebenzisa ivili elinobubanzi Φ 3mm kunye ne-WA # 400 ukususa umaleko we-EDM omhlophe.Kuphinde kubekho ukugaywa kwewhetstone ngesandla, kuhlulwe iwhetstone ngeparafini njengesithambiso okanye into yokupholisa.Umyalelo jikelele wokusetyenziswa ngu #180 ~ #240 ~ #320 ~ #400 ~ #600 ~ #800 ~ #1000.Abenzi bokubumba abaninzi bakhetha ukuqala nge #400 ukonga ixesha.
(2) Ukugulisa kancinci
Ukupholisha kancinci kusebenzisa i-sandpaper kunye ne-kerosene.Amanani sandpaper ngala: #400 ~ #600 ~ #800 ~ #1000 ~ #1200 ~ #1500.Enyanisweni, i-#1500 sandpaper ifaneleka kuphela ukuqina kwentsimbi yokufa (ngaphezulu kwe-52HRC), kungekhona kwintsimbi yangaphambili, kuba inokubangela ukuba umphezulu wentsimbi yangaphambili utshise.
(3) Ukugulisa kakuhle
Ukugulisa okucokisekileyo kusebenzisa intlama yedayimane ebrasive.Ukuba usebenzisa ivili elilaphu lokugulisa ukuxuba idayimani engumgubo wokusila okanye ukucola ukucola ukucola, ulandelelwano lwesiqhelo lokusila 9 μm (#1800) ~ 6 μm (#3000) ~ 3 μm (#8000).A 9 μm diamond intlama kunye nevili ilaphu yokugulisa zingasetyenziswa ukususa amanqaku iinwele ukusuka #1200 kunye #1500 sandpapers.Emva koko ipolishi ngencangathi encangathi kunye nedayimane yokuncamathelisa abrasive, ngokolandelelwano 1 μm (#14000) ~ 1/2 μm (#60000) ~ 1/4 μm (#100000).Iinkqubo zokucwenga ezifuna ukuchaneka ngaphezu kwe-1 μm (kubandakanywa ne-1 μm) zingenziwa kwigumbi lokuhlambela elicocekileyo kwivenkile yokubumba.Ukupholisha okuchanekileyo, indawo ecocekileyo ngokupheleleyo iyafuneka.Uthuli, umsi, inkwethu kunye ne-drool zonke zinako ukuhlehlisa ukugqibezela okugudisiweyo okuphezulu okufumana emva kweeyure zomsebenzi.
Ukupholisha ngoomatshini: Sebenzisa umatshini wokugudisa ibhanti elirhabaxayo ukupolisha isakhelo serola.Okokuqala, sebenzisa i-120 # ibhanti e-abrasive.Xa umbala womphezulu ufikelela kweyokuqala, tshintsha i-240# ibhanti elirhabaxa.Xa umbala womphezulu ufika kowokuqala, tshintsha i 800# ibhanti elirhawukileyo.Ngokukhawuleza ukuba umbala womphezulu ufikile, tshintsha i-1200 # ibhanti e-abrasive, kwaye emva koko uyiphose kwisiphumo sokuhombisa ipleyiti yensimbi engenasici.
Izilumkiso zokupholisha intsimbi engenasici
Ukugaya nge-sandpaper okanye ibhanti eliqhekezayo kumsebenzi wokugaya ngokusisiseko ngumsebenzi wokusika i-polish, ushiya imigca emihle kakhulu ebusweni bentsimbi yensimbi.Kubekho iingxaki nge-alumina njenge-abrasive, ngokuyinxenye ngenxa yemicimbi yoxinzelelo.Naziphi na iindawo ezinqabileyo zezixhobo, ezinjengamabhanti abrasive kunye namavili okugaya, akufanele zisetyenziswe kwezinye izinto ezingenasici ngaphambi kokusetyenziswa.Ngenxa yokuba oku kuya kungcolisa umgangatho wensimbi engenasici.Ukuqinisekisa ukugqitywa komphezulu ohambelanayo, ivili elitsha okanye ibhanti kufuneka lizame kwi-scrap yokwakheka okufanayo ukuze isampuli efanayo ifaniswe.
Umzobo wocingo lwensimbi engenasici kunye nomgangatho wokuhlolwa kokupholisha
- Iimveliso zokukhanya zesibuko sensimbi engenasici
Emva kokuba ukucocwa kugqitywe ngokwenkqubo yokupholisa kunye nokupholisa, umgangatho osemgangathweni ophezulu weemveliso ezigqityiweyo zesibuko zensimbi ezingenasici ziya kwenziwa ngokweTable 2;ukwamkelwa kokuthotywa kuya kwenziwa ngokweTheyibhile 3.

Inqwelo-moya kufuneka ibe mcaba, kwaye kungabikho mphezulu ojikelezayo omaza;umphezulu ogobileyo kufuneka ube mpuluswa, kwaye kungabikho ukuphazamiseka. C. Imiphetho kunye neekona zamacala amabini ahlangabezana neemfuno kwaye azikwazi ukuhlaliswa (ngaphandle kweemfuno ezizodwa) D. Imiphezulu emibini emi nkqo, emva kokupholisha, gcina i-engile echanekileyo eyenziwe yimiphezulu mibini i-symmetrical. Ayizivumeli iintsalela zemigangatho emhlophe xa ishushu kakhulu | |
