Ultra-kiʻekiʻe mana graphite electrodes, ma ka hoololi ana i keleawe electrodes me graphite electrodes no ka mold manufacturing, nui pōkole i ka pōʻaiapili manufacturing pōʻaiapuni, hoʻonui i ka hana huahana, a hoemi i ke kumu kuai poni. I kēia mau makahiki i hala iho nei, me ka hoʻokomo ʻana i nā ʻōleʻa kikoʻī a me nā hoʻoheheʻe kiʻekiʻe (me nā pōkole pōkole ʻoi aku ka pōkole), ua piʻi a kiʻekiʻe nā koi o nā kānaka no ka hana ʻana. Ma muli o nā palena like ʻole o nā electrodes keleawe iā lākou iho, ua ulu ʻole ʻo ia e hoʻokō i nā koi hoʻomohala o ka ʻoihana mold. Ua hoʻohana nui ʻia ʻo Graphite, ma ke ʻano he mea electrode EDM, i ka ʻoihana mold ma muli o kona mau pono e like me ka machinability kiʻekiʻe, ke kaumaha māmā, ka hana wikiwiki, haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa a me ka lole maʻalahi. He mea hikiʻole ke hoʻololi i nā electrodes keleawe.
1. Nā ʻano o nā mea uila graphite
Hōʻike ka mīkini CNC i ka wikiwiki wikiwiki, ka mīkini kiʻekiʻe a me ka lole maʻalahi. ʻO ka wikiwiki o ka hana ʻana o nā mīkini graphite he 3 a 5 mau manawa o nā electrodes keleawe, a ʻoi aku ka maikaʻi o ka wikiwiki o ka hana. Eia kekahi, kiʻekiʻe loa kona ikaika. No nā electrodes ultra-kiʻekiʻe (50 a 90mm) a me ultra-thin (0.2 a 0.5mm), ʻaʻole hiki iā lākou ke hoʻololi i ka wā e hana ai. Eia kekahi, i nā manawa he nui, pono e loaʻa i nā huahana kahi hopena maikaʻi loa. Pono kēia i ka wā e hana ai i nā electrodes, pono lākou e hana ʻia e like me nā electrodes male e like me ka hiki. Eia nō naʻe, aia nā ʻokoʻa huna huna i ka wā o ka hana ʻana o nā electrodes male. Ma muli o ka maʻalahi o ka ʻoki ʻana o ka graphite, hiki ke maʻalahi kēia pilikia a hiki ke hoʻemi nui ʻia ka helu o nā electrodes, ʻaʻole hiki ke hoʻokō i nā electrodes keleawe.
2. Hoʻokumu ʻia ka EDM wikiwiki, hoʻonui ʻia ka wela liʻiliʻi a me ka nalowale haʻahaʻa: Ma muli o ka maikaʻi o ka conductivity uila o ka graphite ma mua o ke keleawe, ʻoi aku ka wikiwiki o kona hoʻokuʻu ʻana ma mua o ke keleawe, ʻo 3 a 5 mau manawa o ke keleawe. Eia kekahi, hiki iā ia ke pale i kahi ʻano nui i ka wā o ka hoʻokuʻu ʻana, ʻoi aku ka maikaʻi no ka mīkini hoʻokuʻu uila. I kēia manawa, ma lalo o ka leo like, ʻo ke kaumaha o ka graphite he 1/5 mau manawa o ke keleawe, kahi e hoʻemi nui ai i ka ukana o EDM. Loaʻa iā ia nā pōmaikaʻi nui i ka hana ʻana i nā electrodes nui a me nā electrodes male integral. ʻO ka mahana sublimation o ka graphite he 4200 ℃, ʻo ia ka 3 a 4 mau manawa o ke keleawe (ʻo ka mahana sublimation o ke keleawe he 1100 ℃). I nā wela kiʻekiʻe, hoʻololi
ʻO ka graphite electrode mana kiʻekiʻe loa
He liʻiliʻi loa kona ʻano (1/3 a 1/5 o ke keleawe ma lalo o nā kūlana uila like) a ʻaʻole palupalu. Hiki ke hoʻololi i ka ikehu hoʻokuʻu i ka mea hana me ka hoʻohana haʻahaʻa. Ma muli o ka hoʻonui maoli ʻana o ka ikaika o ka graphite i nā wela kiʻekiʻe, hiki iā ia ke hōʻemi pono i ka nalowale o ka hoʻokuʻu ʻana (ʻo ka nalowale o ka graphite he 1/4 o ke keleawe), e hōʻoia ana i ka maikaʻi o ka hana.
3. ʻO ke kaumaha māmā a me ke kumukūʻai haʻahaʻa: Ma ke kumukūʻai hana o kahi hoʻonohonoho o nā mold, ka manawa mīkini CNC, ka manawa EDM, a me ke kāhiko electrode o nā electrodes helu no ka hapa nui o ka huina kālā, a ua hoʻoholoʻia kēia mau mea a pau e ka mea electrode pono'ī. Ke hoʻohālikelikeʻia me ke keleawe,ʻo ka wikiwiki o ka mīkini a me ka wikiwiki EDM o ka graphite he 3 a 5 mau manawa o ke keleawe. I kēia manawa, hiki i ka hiʻohiʻona o ka lole liʻiliʻi a me ka hana ʻana o ka electrode graphite integral hiki ke hōʻemi i ka helu o nā electrodes, a laila e hōʻemi i ka hoʻohana ʻana i nā mea a me ka manawa mīkini o nā electrodes. Hiki i kēia mau mea a pau ke hoʻemi nui i ke kumukūʻai hana o nā molds
2. Nā Koina a me nā ʻano o ka hana ʻenehana a me ka uila o nā Electrodes Graphite
1. ʻO ka hanaʻana o nā electrodes: Hoʻohana nui ka hana graphite electrode ʻoihana i nā mea mīkini kiʻekiʻe no ka hana ʻana. Pono ka paʻa paʻa o ka mīkini, me ka ʻaʻahu a paʻa i nā neʻe ʻekolu-axis me ka haʻalulu ʻole. Eia kekahi, ʻoi aku ka maikaʻi o ka rotational pololei o nā ʻāpana e like me ke kumu nui. Hiki ke hana ʻia ka electrode ma nā mea mīkini maʻamau, akā ʻokoʻa ke kaʻina hana o ke kākau ʻana i ke ala hāmeʻa mai nā electrodes keleawe.
2.EDM uila hoʻokuʻu machining graphite electrodes he kalapona electrodes. Ma muli o ka maikaʻi o ka conductivity uila o ka graphite, hiki iā ia ke mālama i ka manawa nui i ka mīkini hoʻokuʻu uila, ʻo ia kekahi o nā kumu i hoʻohana ʻia ai ka graphite ma ke ʻano he electrode.
3. Nā ʻano o ka hana ʻana o nā Electrodes Graphite: He paʻakikī a palupalu ka graphite ʻoihana, e hoʻokau i ka ʻaʻahu koʻikoʻi ma luna o nā mea hana i ka wā CNC machining. ʻO ka maʻamau, ʻōlelo ʻia e hoʻohana i nā mea hana i uhi ʻia me ka alloy paʻa a i ʻole ke daimana. I ka wā e hana ai i ka graphite machining, hiki ke kau pololei i ka mea hana ma luna a ma waho o ka mea hana. Eia nō naʻe, i ka hoʻopau ʻana i ka mīkini, i mea e pale ai i ka ʻoki ʻana a me ka haki ʻana, hoʻohana pinepine ʻia kahi mea hana māmā a me ke ala hele wikiwiki.
ʻO ka ʻōlelo maʻamau, ʻaʻole e haki ka graphite i ka wā i emi ai ka hohonu o ka ʻoki ʻana ma mua o 0.2mm, a hiki ke loaʻa i kahi ʻoi aku ka maikaʻi o ka ʻaoʻao o ka paia ʻaoʻao. ʻO ka lepo i hanaʻia ma ka CNC machining o graphite electrodes he mea nui a hiki ke hoʻouka i nā alakaʻi alakaʻi, ke alakaʻi wili a me nā spindles o ka mīkini mea hana, a me nā mea'ē aʻe. ʻO ka pauka Graphite kahi mea i paʻakikī loa i nā hopena kemika. Hoʻololi kona resistivity i nā kaiapuni like ʻole, ʻo ia hoʻi, ʻokoʻa kona waiwai kū'ē. Eia nō naʻe, hoʻokahi mea e mau nei: ʻo ka pauka graphite kekahi o nā mea conductive non-metallic maikaʻi loa. ʻOiai ka lōʻihi o ka mālama ʻia ʻana o ka pauda graphite i loko o kahi mea hoʻokaʻawale ʻole, e like me ke kaula lahilahi, e hoʻomau ʻia ka uila. Akā, he aha ka waiwai kū'ē? ʻAʻohe helu kikoʻī no kēia waiwai, no ka mea, ʻokoʻa ka maikaʻi o ka pauda graphite, a ʻokoʻa hoʻi ka waiwai kūʻē o ka pauda graphite i hoʻohana ʻia i nā mea like ʻole a me nā kaiapuni.
ʻAʻole paha ʻoe i ʻike he hoʻohana conductive ka pauka graphite kiʻekiʻe.
ʻO ka maʻamau, hoʻokaʻawale ka lāʻau. Inā makemake ʻia ka conductivity uila, pono e hoʻohui ʻia nā mea conductive. ʻO ka pauka Graphite he conductivity uila maikaʻi loa a me nā waiwai demolding lubricating. Hoʻopili ʻia ka graphite i ka pauka graphite, nona ka lubricating maikaʻi a me nā waiwai conductive. ʻOi aku ka maʻemaʻe o ka pauka graphite, ʻoi aku ka maikaʻi o kāna hana conductive. He nui nā hale hana hoʻoheheʻe koʻikoʻi e pono ai ka lāʻau conductive. A laila, hiki ke hoʻohui ʻia ka pauda graphite i ka ʻōpala e hoʻokele i ka uila? ʻO ka pane he ʻae, akā aia kekahi nīnau: He aha ka hapa o ka pauka graphite i loko o ka lāʻau? Ke hoʻohana nei kekahi mau ʻoihana i ka hapa o ka 30%, kahi i hoʻohana ʻia i nā huahana palaki e like me nā kaʻa kaʻa, a me nā mea ʻē aʻe. ʻO ia mau huahana wale nō e hiki ke hoʻokele uila. ʻO ke kumu kumu o ka conductivity ʻaʻole hiki ke hoʻopau ʻia ka conductor, e like me ka uea. Inā hoʻopau ʻia i ka waena, ʻaʻole ia e uila. ʻO ka pauda graphite conductive i loko o ka lāʻau conductive ka mea hoʻokele inā ua ālai ʻia ka pauda graphite e ka lāʻau insulating, ʻaʻole ia e holo hou i ka uila. No laila, inā haʻahaʻa loa ka hapa o ka pauka graphite, ʻilihune paha ka hopena conductive.
ʻO ka pauka Graphite kahi mea i paʻakikī loa i nā hopena kemika. Hoʻololi kona resistivity i nā kaiapuni like ʻole, ʻo ia hoʻi, ʻokoʻa kona waiwai kū'ē. Eia nō naʻe, hoʻokahi mea e mau nei: ʻo ka pauka graphite maʻemaʻe kiʻekiʻe ʻo ia kekahi o nā mea conductive non-metallic maikaʻi loa. ʻOiai ka lōʻihi o ka mālama ʻia ʻana o ka pauda graphite i loko o kahi mea hoʻokaʻawale ʻole, e like me ke kaula lahilahi, e hoʻomau ʻia ka uila. Akā, he aha ka waiwai kū'ē? ʻAʻohe helu kikoʻī no kēia waiwai, no ka mea, ʻokoʻa ka maikaʻi o ka pauda graphite, a ʻokoʻa hoʻi ka waiwai kūʻē o ka pauda graphite i hoʻohana ʻia i nā mea like ʻole a me nā kaiapuni.
