IiBurrs zikuyo yonke indawo kwinkqubo yokwenziwa kwesinyithi. Nokuba usebenzisa izixhobo ezichanekileyo kangakanani na, ziya kuzalwa kunye nemveliso. Ikakhulu luhlobo lweefayili zentsimbi ezigqithisiweyo eziveliswe kumda wokulungiswa kwezinto eziza kucutshungulwa ngenxa yokuguqulwa kweplastiki yezinto. Ngokukodwa izixhobo ezine-ductility elungileyo okanye ukuqina zithandwa kakhulu kwi-burrs.
Iindidi eziphambili zeebhula ziquka ii-flash burrs, iikona ezibukhali, i-spatter kunye nezinye iintsalela zentsimbi eziphumayo ezingahlangabezani neemfuno zoyilo lwemveliso. Ngokumalunga nale ngxaki, akukho ndlela isebenzayo yokuyiphelisa kwinkqubo yokuvelisa ukuza kuthi ga ngoku. Ngoko ke, ukwenzela ukuba kuqinisekiswe iimfuno zoyilo lwemveliso, iinjineli zinokusebenza nzima kuphela ekususweni kwenkqubo yokubuyela emva. Ukuza kuthi ga ngoku, iimveliso ezahlukeneyo zineemfuno ezahlukeneyo. Zininzi iindlela kunye nezixhobo zokususa ii-burrs.
Izixhobo ze-Xinfa ze-CNC zineempawu zomgangatho omhle kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:

Ngokuqhelekileyo, iindlela zokususa i-burr zinokwahlulwa zibe ziindidi ezine:
1. Inqanaba elirhabaxa (uqhagamshelo olunzima)
Ukolu didi kukusika, ukugaya, ukufayila kunye nokulungiswa kwe-scraper.
2. Inqanaba eliqhelekileyo (ukubamba okuthambileyo)
Kolu didi kukusila ibhanti, ukucolwa, ukucola ivili elilastiki kunye nokupholisha.
3. Inqanaba elichanekileyo (uqhagamshelwano oluguquguqukayo)
Kolu didi kukugungxulwa, ukusetyenzwa kwe-electrochemical, ukucola i-electrolytic kunye nokuqengqeleka.
4. Inqanaba lokuchaneka kakhulu (uqhagamshelwano oluchanekileyo)
Ukuphuma kolu didi kukukhupha i-abrasive flow deburring, i-magnetic grinding deburring, i-electrolytic deburring, i-thermal deburring kunye ne-dense radium enamandla ye-ultrasonic deburring, njl.
Xa sikhetha indlela yokucima, kufuneka siqwalasele izinto ezininzi, ezifana neempawu zezinto eziphathekayo zenxalenye, ubume besakhiwo, ubungakanani kunye nokuchaneka. Ngokukodwa, kufuneka sinikele ingqalelo kutshintsho kuburhabaxa bomphezulu, ukunyamezelwa komgangatho, ukuguqulwa, kunye noxinzelelo olushiyekileyo.
Into ebizwa ngokuba yi-electrolytic deburring yindlela yokuchithwa kweekhemikhali. Inokususa i-burrs emva komatshini, ukucola kunye nokunyathela, kwaye ijikeleze okanye idibanise imiphetho ebukhali yeendawo zetsimbi.
Indlela yokucubungula i-electrolytic esebenzisa i-electrolysis ukususa i-burrs kwiindawo zentsimbi, ezibizwa ngokuba yi-ECD ngesiNgesi. Lungisa i-cathode yesixhobo (ehlala yenziwe ngobhedu) kufuphi ne-burr inxalenye yomsebenzi, kunye ne-gap ethile (ngokuqhelekileyo i-0.3 ukuya ku-1 mm) phakathi kwabo. Inxalenye eqhubayo yecathode yesixhobo ihambelana ne-burr edge, kwaye ezinye iindawo zigqunywe ngongqimba olukhuselayo ukuze kugxininise i-electrolysis kwinxalenye ye-burr.
Ngethuba lokucubungula, i-cathode yesixhobo idibaniswe kwipali engafanelekanga yonikezelo lwamandla e-DC, kwaye i-workpiece iqhagamshelwe kwipali echanekileyo ye-DC power supply. I-electrolyte ephantsi yoxinzelelo (ngokuqhelekileyo i-nitrate ye-sodium okanye i-sodium chlorate isisombululo se-aqueous) kunye noxinzelelo lwe-0.1 ukuya kwi-0.3 MPa ihamba phakathi kwe-workpiece kunye ne-cathode. Xa umbane we-DC uvuliwe, i-burrs iya kunyibilika kwi-anode kwaye isuswe, kwaye iya kuthathwa yi-electrolyte.
I-electrolyte i-corrosion ukuya kwinqanaba elithile, kwaye i-workpiece kufuneka icocwe kwaye i-rust-proofed emva kokuchithwa. I-Electrolytic deburring ifanelekile ukususa i-burrs kwimingxunya enqamlezileyo kwiindawo ezifihlakeleyo okanye iindawo ezinemilo enzima. Inomgangatho ophezulu wemveliso kwaye ixesha lokuhlawula lithatha kuphela imizuzwana embalwa ukuya kumashumi emizuzwana.
Le ndlela iqhele ukusetyenziselwa ukudiliza iigiya, i-splines, i-rods yokudibanisa, imizimba yevalve kunye nokuvuleka kweoyile ye-crankshaft, kunye nokujikeleza okubukhali kwikona, njl njl. Ububi kukuba iindawo ezikufutshane ne-burrs nazo zichatshazelwa yi-electrolysis, kwaye umphezulu uya ilahlekelwe ukubengezela kwayo kwasekuqaleni kwaye ichaphazele nokuchaneka komda.
Ewe kunjalo, ukongeza ekususweni kwe-electrolytic burr, kukwakho ezi ndlela zilandelayo zokususa i-burr:
1. I-Abrasive flow deburring
Itekhnoloji ye-Abrasive flow machining technology (AFM) yinkqubo entsha yokugqibezela kunye neyokususwa kwezixhobo eziphuhliswe phesheya ekupheleni kweminyaka yoo-1970. Le nkqubo ifaneleka ngokukodwa kwii-burrs ezisanda kungena kwinqanaba lokugqiba, kodwa ayifanelekanga imingxuma emincinci kunye nemide kunye nezibunji zetsimbi ezinezingqimba ezivaliweyo. njl. azifanelekanga ukuqhubekekiswa.
2. Ukusila ngemagnethi kunye nokuchithwa
Le ndlela yaqala kwindawo eyayisakuba yiSoviet Union, eBulgaria nakwamanye amazwe aseMpuma Yurophu ngeminyaka yoo-1960. Phakathi kwiminyaka yee-1980, abavelisi baseJapan benza uphando olunzulu malunga nendlela kunye nokusetyenziswa kwayo.
Ngexesha lokugaya magnetic, i-workpiece ifakwe kwi-magnetic field eyenziwe ngezibonda ezimbini zemagnethi, kwaye i-abrasives magnetic ifakwe kwi-gap phakathi kwendawo yokusebenza kunye neepali zemagneti. Iibrasives zicwangciswe kakuhle ecaleni kwendlela yemigca yemagnethi phantsi kwesenzo samandla ombane wemagnethi, zenza umatshini wokusila othambileyo noqinileyo. I-Brush, xa i-workpiece ijikeleza kwaye ishukuma i-axially kwintsimi yamagnetic, i-workpiece kunye ne-abrasive move ngokubhekiselele komnye nomnye, kunye ne-brush abrasive igaya ubuso bomsebenzi; indlela yokugaya yamagnetic inokugaya kunye ne-deburr iinxalenye ngokufanelekileyo kwaye ngokukhawuleza, kwaye ifanelekile Yindlela yokugqiba kunye notyalo-mali oluphantsi, ukusebenza okuphezulu, ukusetyenziswa okubanzi kunye nomgangatho omhle wezinto ezenziwe ngezinto ezahlukeneyo, ubukhulu kunye nezakhiwo.
Okwangoku, amazwe angaphandle angakwazi ukugaya kunye nokucima indawo yangaphakathi nangaphandle yomzimba ojikelezayo, iinxalenye ezisicaba, amazinyo egiya, iindawo ezinzima, njl., Susa isikali se-oxide kwiingcingo, kwaye uhlambulule iibhodi zeesekethe eziprintiweyo, njl.
3. Ukuchithwa kwe-thermal
I-Thermal deburring (TED) isebenzisa ubushushu obuphezulu obuveliswa ngokuchithwa komxube we-hydrogen kunye ne-oxygen gas okanye i-oxygen kunye negesi yendalo ukutshisa i-burrs. Kukugqithisa ioksijini kunye neoksijini okanye igesi yendalo kunye neoksijini kwisitya esivaliweyo, kwaye uyitshise nge-spark plug, ukuze umxube uqhume ngephanyazo kwaye ukhuphe isixa esikhulu samandla obushushu ukususa i-burrs. Nangona kunjalo, emva kokuba i-workpiece iqhume ukutsha, i-powder yayo ene-oxidized iya kubambelela kumphezulu we-workpiece kwaye kufuneka icocwe okanye ifakwe emanzini.
4. I-MiLa i-ultrasonic deburring enamandla
Itekhnoloji ye-MiLa enamandla ye-ultrasonic deburring yindlela yokucima esele idumile kwiminyaka yakutshanje. Ukusebenza kakuhle kokucoca kuphela ngamaxesha angama-10 ukuya kwangama-20 oomatshini abaqhelekileyo bokucoca i-ultrasonic. Imingxuma isasazwa ngokulinganayo kwitanki yamanzi, ukuphelisa imfuno yokucoca i-ultrasonic. Umthamo ungagqitywa ngaxeshanye ngaphakathi kwe-5 ukuya kwi-15 imizuzu.
