Chida chodulira
Mu makina ochapira mofulumira kwambiri a graphite, chifukwa cha kuuma kwa zinthu za graphite, kusokonekera kwa mapangidwe a chip komanso mphamvu ya mawonekedwe ochapira mwachangu kwambiri, kupsinjika kosinthana kwa kudula kumapangidwa panthawi yodula ndipo kugwedezeka kwina kumapangidwa, ndipo chidacho chimatha kugwetsa nkhope ndi mphepete. Kuphulika kumakhudza kwambiri moyo wa chipangizocho, kotero chida chomwe chimagwiritsidwa ntchito pochapira mwachangu kwambiri cha graphite chimafuna kukana kuwonongeka kwambiri komanso kukana kuwonongeka.
Zipangizo zopakidwa ndi diamondi zili ndi ubwino wa kuuma kwambiri, kukana kutopa kwambiri, komanso kusagwirizana kochepa. Pakadali pano, zida zopakidwa ndi diamondi ndiye chisankho chabwino kwambiri chogwiritsira ntchito graphite.
Zipangizo zodulira graphite ziyeneranso kusankha ngodya yoyenera, yomwe imathandiza kuchepetsa kugwedezeka kwa zida, kukonza bwino makina, komanso kuchepetsa kuwonongeka kwa zida. Kafukufuku wa akatswiri aku Germany pa njira yodulira graphite akuwonetsa kuti kuchotsa graphite panthawi yodulira graphite kumagwirizana kwambiri ndi ngodya ya rake ya chida. Kudula ngodya ya rake yoipa kumawonjezera kupsinjika, komwe kumathandiza kulimbikitsa kuphwanyidwa kwa zinthuzo, kukonza magwiridwe antchito, ndikupewa kupanga zidutswa zazikulu za graphite.
Mitundu yodziwika bwino ya zida zodulira mwachangu kwambiri za graphite ndi monga ma end mills, ma ball-end cutters ndi ma fillet milling cutters. Ma end mills nthawi zambiri amagwiritsidwa ntchito pokonza pamwamba ndi mawonekedwe osavuta. Ma ball-end milling cutters ndi zida zabwino kwambiri zokonzera malo opindika. Ma fillet milling cutters ali ndi mawonekedwe a ma ball-end cutters ndi ma end mills, ndipo angagwiritsidwe ntchito pamalo opindika komanso athyathyathya. Pokonza.
magawo odulira
Kusankha magawo oyenera odulira panthawi yodulira mwachangu kwambiri ya graphite ndikofunikira kwambiri pakukweza ubwino ndi magwiridwe antchito a workpiece. Popeza njira yodulira graphite yodulira mwachangu kwambiri ndi yovuta kwambiri, posankha magawo odulira ndi njira zodulira, muyenera kuganizira kapangidwe ka workpiece, mawonekedwe a zida zamakina, zida, ndi zina zotero. Pali zinthu zambiri, zomwe zimadalira kwambiri kuyesa kwakukulu kodulira.
Pazinthu zopangira graphite, ndikofunikira kusankha magawo odulira omwe ali ndi liwiro lalikulu, chakudya chachangu, komanso zida zambiri munjira yopangira makina okhwima, zomwe zingathandize bwino ntchito yopangira makina; koma chifukwa graphite imakonda kusweka panthawi yopangira makina, makamaka m'mphepete, ndi zina zotero. Malo ake ndi osavuta kupanga mawonekedwe opindika, ndipo liwiro la chakudya liyenera kuchepetsedwa moyenera pamalo awa, ndipo sikoyenera kudya mpeni wambiri.
Pa zigawo za graphite zokhala ndi makoma owonda, zifukwa zomwe zimachititsa kuti m'mphepete ndi m'makona zidulidwe makamaka zimayambitsidwa ndi kugwedezeka kwa kudula, kulola mpeni ndi mpeni wotambasuka, komanso kusinthasintha kwa mphamvu yodula. Kuchepetsa mphamvu yodula kumatha kuchepetsa mpeni ndi mpeni wa zipolopolo, kukonza bwino momwe zinthu za graphite zokhala ndi makoma owonda zimagwirira ntchito, komanso kuchepetsa kusweka ndi kusweka kwa ngodya.
Liwiro la spindle la malo opangira makina othamanga kwambiri a graphite nthawi zambiri limakhala lalikulu. Ngati mphamvu ya spindle ya chida cha makina ilola, kusankha liwiro lalikulu lodulira kungachepetse mphamvu yodulira, ndipo magwiridwe antchito amatha kukonzedwa bwino; pankhani yosankha liwiro la spindle, kuchuluka kwa chakudya pa dzino lililonse kuyenera kusinthidwa kuti kugwirizane ndi liwiro la spindle kuti chakudya chisachepe kwambiri komanso chida chachikulu chisawononge. Kudula graphite nthawi zambiri kumachitika pa chida chapadera cha makina a graphite, liwiro la makina nthawi zambiri limakhala 3000 ~ 5000r/min, ndipo liwiro la chakudya nthawi zambiri limakhala 0.5~1m/min, sankhani liwiro lotsika kwambiri la makina okhwima komanso liwiro lalikulu lomaliza. Pa malo opangira makina othamanga kwambiri a graphite, liwiro la chida cha makina ndi lalikulu, nthawi zambiri pakati pa 10000 ndi 20000r/min, ndipo kuchuluka kwa chakudya nthawi zambiri kumakhala pakati pa 1 ndi 10m/min.
Malo Opangira Machining a Graphite High Speed
Fumbi lalikulu limapangidwa panthawi yodula graphite, zomwe zimaipitsa chilengedwe, zimakhudza thanzi la ogwira ntchito, komanso zimakhudza zida zamakina. Chifukwa chake, zida zamakina opangira graphite ziyenera kukhala ndi zida zabwino zoteteza fumbi komanso zochotsa fumbi. Popeza graphite ndi chinthu choyendetsa, kuti fumbi la graphite lomwe limapangidwa panthawi yokonza lisalowe m'zigawo zamagetsi za chipangizo chamakina ndikuyambitsa ngozi zachitetezo monga ma short circuits, zida zamagetsi za chipangizo chamakina ziyenera kutetezedwa ngati pakufunika kutero.
Malo opangira makina othamanga kwambiri a graphite amagwiritsa ntchito spindle yamagetsi yothamanga kwambiri kuti akwaniritse liwiro lalikulu, ndipo kuti achepetse kugwedezeka kwa chida cha makina, ndikofunikira kupanga kapangidwe kotsika ka mphamvu yokoka. Njira yoperekera chakudya nthawi zambiri imagwiritsa ntchito screw yothamanga kwambiri komanso yolondola kwambiri, ndipo imapanga zida zotsutsana ndi fumbi [7]. Liwiro la spindle la malo opangira makina othamanga kwambiri a graphite nthawi zambiri limakhala pakati pa 10000 ndi 60000r/min, liwiro la chakudya likhoza kukhala lalikulu ngati 60m/min, ndipo makulidwe a khoma lopangira akhoza kukhala ochepera 0.2 mm, khalidwe la pamwamba pa ntchito yopangira ndi kulondola kwa ntchito ya zigawozo ndi lalikulu, yomwe ndi njira yayikulu yopezera ntchito yogwira ntchito bwino komanso yolondola kwambiri yopangira graphite pakadali pano.
Pogwiritsa ntchito kwambiri zipangizo za graphite komanso chitukuko cha ukadaulo wokonza graphite mwachangu, zida zogwiritsira ntchito graphite zapamwamba kwambiri kunyumba ndi kunja kwa dzikolo zawonjezeka pang'onopang'ono. Chithunzi 1 chikuwonetsa malo opangira graphite mwachangu kwambiri opangidwa ndi opanga ena am'nyumba ndi akunja.
GR400 ya OKK imagwiritsa ntchito kapangidwe kotsika kwambiri ka mphamvu yokoka ndi kapangidwe ka mlatho kuti ichepetse kugwedezeka kwa makina a chida cha makina; imagwiritsa ntchito chitsogozo cha C3 cholondola cha screw ndi roller kuti iwonetsetse kuti chida cha makina chikufulumira kwambiri, kuchepetsa nthawi yokonza, ndikuwonjezera zoteteza ku splash. Kapangidwe kachitsulo kotsekedwa bwino ka chivundikiro cha pamwamba pa makina kamaletsa fumbi la graphite. Njira zopewera fumbi zomwe Haicheng VMC-7G1 idagwiritsa ntchito si njira yodziwika bwino yotsukira fumbi, koma mawonekedwe otseka nsalu yamadzi, ndipo chipangizo chapadera cholekanitsa fumbi chimayikidwa. Zigawo zosuntha monga njanji zowongolera ndi ndodo zokulungira zilinso ndi zipolopolo ndi chipangizo champhamvu chokokera kuti zitsimikizire kuti chida cha makina chikugwira ntchito bwino kwa nthawi yayitali.
Zikuoneka kuchokera ku magawo ofotokozera a malo opangira makina othamanga kwambiri a graphite mu Table 1, kuti liwiro la spindle ndi liwiro la chakudya cha chida cha makina ndi lalikulu kwambiri, zomwe ndi khalidwe la makina othamanga kwambiri a graphite. Poyerekeza ndi mayiko akunja, malo opangira makina a graphite m'dziko muno alibe kusiyana kwakukulu pazida zamakina. Chifukwa cha kusonkhanitsa zida zamakina, ukadaulo ndi kapangidwe kake, kulondola kwa makina a zida zamakina ndikochepa. Chifukwa cha kugwiritsidwa ntchito kwa graphite m'makampani opanga, malo opangira makina othamanga kwambiri a graphite akoka chidwi chachikulu. Malo opangira makina a graphite ogwira ntchito bwino komanso ogwira ntchito bwino amapangidwa ndikupangidwa. Ukadaulo wokonza bwino umatengedwa kuti upereke mawonekedwe ake ndi magwiridwe antchito ake kuti graphite iwongolere. Kugwira ntchito bwino kwa zinthu ndi mtundu wa zigawo ndizofunikira kwambiri pakukweza ukadaulo wokonza makina a graphite m'dziko langa.
powombetsa mkota
Nkhaniyi ikufotokoza makamaka za njira yopangira graphite kuchokera ku mbali za makhalidwe a graphite, njira yodulira ndi kapangidwe ka malo opangira graphite othamanga kwambiri. Ndi chitukuko chopitilira cha ukadaulo wa zida zamakina ndi ukadaulo wa zida, ukadaulo wopanga graphite wothamanga kwambiri umafunika kafukufuku wozama kudzera mu mayeso odulira ndi ntchito zothandiza kuti ukonze luso la makina opangira graphite m'malingaliro ndi machitidwe.
