Kafukufuku wa Graphite Machining Process 2

Mu makina othamanga kwambiri a graphite, chifukwa cha kuuma kwa zinthu za graphite, kusokonezeka kwa mapangidwe a chip ndi kukhudzidwa kwa makhalidwe odula kwambiri, kusinthasintha kwa kudula kumapangidwira panthawi yodula ndipo kugwedezeka kwina kumapangidwa. chida sachedwa kugwetsa nkhope ndi m'mbali nkhope Abrasion kwambiri zimakhudza moyo utumiki wa chida, choncho chida ntchito machining graphite mkulu-liwiro amafuna mkulu kuvala kukana ndi kukana mphamvu.

Zida zokutira za diamondi zili ndi zabwino zake zolimba kwambiri, kukana kuvala kwambiri, komanso kugundana kochepa. Pakadali pano, zida zokutira za diamondi ndizosankha bwino kwambiri pakukonza ma graphite.

Zida zamakina a graphite zimafunikiranso kusankha mawonekedwe oyenera a geometric, omwe amathandizira kuchepetsa kugwedezeka kwa zida, kukonza makina abwino, komanso kuchepetsa kuvala kwa zida. Kafukufuku wa akatswiri a ku Germany pa makina odula ma graphite akusonyeza kuti kuchotsa ma graphite panthawi yodula ma graphite kumagwirizana kwambiri ndi njira yopangira graphite. Kudulira koyipa kwa ngodya kumawonjezera kupsinjika, komwe kumapindulitsa kulimbikitsa kuphwanyidwa kwazinthu, kukonza magwiridwe antchito, ndikupewa kupanga zidutswa zazikuluzikulu za graphite.

Mitundu yodziwika bwino ya zida zodulira mwachangu kwambiri za graphite imaphatikizapo mphero zomaliza, zodulira zodulira mpira ndi ocheka mphero. Makina omalizira amagwiritsidwa ntchito pokonza pamwamba ndi ndege zosavuta komanso mawonekedwe. Odulira mphero ndi zida zabwino pokonza malo opindika. Odulira mphero ali ndi mawonekedwe a onse ocheka-mapeto a mpira ndi mphero zomaliza, ndipo amatha kugwiritsidwa ntchito pazokhotakhota komanso zathyathyathya. Kwa processing.

Kudula magawo

Kusankhidwa kwa magawo oyenera odulira panthawi yodula kwambiri ya graphite ndikofunikira kwambiri pakuwongolera magwiridwe antchito ndi magwiridwe antchito. Popeza kudula ndondomeko graphite mkulu-liwiro Machining ndi zovuta kwambiri, posankha magawo kudula ndi njira processing, muyenera kuganizira workpiece kapangidwe, makina chida makhalidwe, zida, etc. Pali zinthu zambiri, amene makamaka amadalira ambiri. zoyesera zodula.

Pakuti zipangizo graphite, m'pofunika kusankha magawo kudula ndi liwilo, kudya chakudya, ndi kuchuluka kwa chida mu akhakula Machining ndondomeko, amene akhoza bwino kusintha Machining dzuwa; koma chifukwa graphite sachedwa chipping pa ndondomeko Machining, makamaka m'mbali, etc. udindo n'zosavuta kupanga mawonekedwe okhotakhota, ndi liwiro chakudya ayenera moyenera kuchepetsedwa pa malo amenewa, ndipo si koyenera kudya lalikulu. kuchuluka kwa mpeni.

Pazigawo zopyapyala zokhala ndi mipanda ya graphite, zifukwa zodulira m'mbali ndi m'makona zimayamba chifukwa cha kugunda, kulola mpeni ndi mpeni zotanuka, komanso kusinthasintha kwamphamvu. Kuchepetsa mphamvu yodulira kumatha kuchepetsa mpeni ndi mpeni wa zipolopolo, kupititsa patsogolo kukonzedwa kwa magawo a graphite okhala ndi mipanda yopyapyala, komanso kuchepetsa kutsika kwapangodya ndi kuthyoka.

Liwiro la spindle la graphite high-speed Machining center nthawi zambiri limakulirakulira. Ngati mphamvu ya spindle ya chida cha makina imalola, kusankha kuthamanga kwapamwamba kumatha kuchepetsa mphamvu yodulira, komanso kukonza bwino kumatha kusintha kwambiri; posankha liwiro la spindle, Kuchuluka kwa chakudya pa dzino kuyenera kusinthidwa ndi liwiro la spindle kuti tipewe chakudya chofulumira komanso chida chachikulu choyambitsa kudumpha. Graphite kudula kawirikawiri ikuchitika pa chida chapadera graphite makina chida, liwiro la makina zambiri 3000 ~ 5000r/mphindi, ndi liwiro chakudya zambiri 0. 5 ~ 1m/mphindi, kusankha ndi otsika liwiro Machining akhakula ndi liwilo. kwa kumaliza. Kwa malo opangira makina othamanga kwambiri a graphite, liwiro la chida cha makina ndilokwera kwambiri, nthawi zambiri pakati pa 10000 ndi 20000r/mphindi, ndipo kuchuluka kwa chakudya kumakhala pakati pa 1 ndi 10m/mphindi.

Graphite High Speed ​​​​Machining Center

Fumbi lalikulu limapangidwa panthawi yodula ma graphite, zomwe zimawononga chilengedwe, zimakhudza thanzi la ogwira ntchito, komanso zimakhudza zida zamakina. Chifukwa chake, zida zamakina opangira ma graphite ziyenera kukhala ndi zida zabwino zopanda fumbi komanso zochotsa fumbi. Popeza kuti graphite ndi thupi loyendetsa, pofuna kuteteza fumbi la graphite lomwe limapangidwa panthawi yokonza kuti lilowe m'zigawo zamagetsi za chida cha makina ndikuyambitsa ngozi za chitetezo monga maulendo afupikitsa, zigawo zamagetsi za makina opangira makina ziyenera kutetezedwa ngati kuli kofunikira.

Graphite mkulu-liwiro Machining center utenga mkulu-liwiro spindle magetsi kuti tikwaniritse liwiro, ndi kuchepetsa kugwedezeka kwa makina chida, m'pofunika kupanga malo otsika mphamvu yokoka dongosolo. Makina odyetsera nthawi zambiri amatengera kuthamanga kwambiri komanso kulondola kwambiri kwa mpira, ndikupanga zida zothana ndi fumbi [7]. Liwiro la spindle la graphite likulu lothamanga kwambiri la Machining nthawi zambiri limakhala pakati pa 10000 ndi 60000r/mphindi, liwiro la chakudya likhoza kukhala lokwera mpaka 60m/mphindi, ndi makulidwe a khoma la processing akhoza kukhala osakwana 0. 2 mm, khalidwe lapamwamba komanso processing kulondola kwa mbali ndi mkulu, amene ndi njira yaikulu kukwaniritsa mkulu-mwachangu ndi mkulu-mwatsatanetsatane processing wa graphite panopa.

Ndi ntchito lonse la zipangizo graphite ndi chitukuko cha mkulu-liwiro graphite processing luso, mkulu-ntchito graphite processing zipangizo kunyumba ndi kunja pang'onopang'ono chawonjezeka. Chithunzi 1 chikuwonetsa malo opangira makina othamanga kwambiri a graphite opangidwa ndi opanga ena apakhomo ndi akunja.

OKK's GR400 imatenga malo otsika a mphamvu yokoka ndi kapangidwe ka mlatho kuti muchepetse kugwedezeka kwamakina kwa chida; amatengera C3 mwatsatanetsatane screw ndi wodzigudubuza kuonetsetsa kuti mkulu mathamangitsidwe chida makina, kufupikitsa nthawi kukonza, ndi kutengera kuwonjezera alonda splash Mapangidwe otsekedwa kwathunthu zitsulo chivundikiro chapamwamba makina amateteza graphite fumbi. Njira zowonetsera fumbi zomwe zimatengedwa ndi Haicheng VMC-7G1 si njira yomwe imagwiritsidwa ntchito kawirikawiri, koma mawonekedwe osindikizira a chinsalu chamadzi, ndipo chipangizo chapadera cholekanitsa fumbi chimayikidwa. Zigawo zosuntha monga njanji zowongolera ndi nsonga zomangira zimakhalanso ndi sheaths ndi Zamphamvu scraping chipangizo kuonetsetsa ntchito yokhazikika kwa nthawi yayitali ya chida cha makina.

Zitha kuwoneka pazigawo zodziwika bwino za graphite yothamanga kwambiri mu Table 1, kuti liwiro la spindle ndi liwiro la chida cha makina ndi lalikulu kwambiri, lomwe ndi mawonekedwe a makina othamanga kwambiri a graphite. Poyerekeza ndi mayiko akunja, malo opangira ma graphite apanyumba ali ndi kusiyana kochepa pamakina a zida zamakina. Chifukwa cha kusonkhanitsa zida zamakina, ukadaulo ndi kapangidwe kake, kulondola kwa zida zamakina ndizochepa. Chifukwa cha kufala kwa graphite m'makampani opanga zinthu, malo opangira makina othamanga kwambiri akopa chidwi kwambiri. Malo opangira makina a graphite opangidwa bwino kwambiri komanso apamwamba kwambiri amapangidwa ndikupangidwa. The wokometsedwa processing luso anatengera kupereka sewero lathunthu kwa makhalidwe ake ndi ntchito kusintha graphite. Kukonzekera bwino ndi ubwino wa zigawo ndizofunika kwambiri kupititsa patsogolo luso lamakono lamakono la graphite.

powombetsa mkota

Nkhaniyi makamaka ikukamba za graphite Machining ndondomeko ku mbali ya makhalidwe graphite, kudula ndondomeko ndi dongosolo la graphite mkulu-liwiro Machining pakati. Ndi chitukuko chosalekeza cha ukadaulo wa zida zamakina ndi ukadaulo wa zida, ukadaulo waukadaulo wa graphite wothamanga kwambiri umafunika kufufuza mozama kudzera m'mayesero odulira ndikugwiritsa ntchito zothandiza kuti apititse patsogolo luso laukadaulo la graphite Machining mu chiphunzitso ndi machitidwe.
