Pehea e koho ai i nā mea hana pōhaku Drill
Pehea e koho ai i nā mea hana pōhaku Drill
KaʻAnuʻu Hana 1: E hoʻoholo i ka Shank Configuration ma kāu Drill.
ʻO ka hana mua i ke koho ʻana i ka ponokila a me nā ʻāpanano ka hoʻoholo ʻana i ka hoʻonohonoho ʻana o ka shank ma kāu drill.
He 3 wale nō ka nui o ka shank maʻamau. 7/8 x 3 ¼”, 7/8 x 4 ¼” a me 1 x 4 ¼”. ʻO kēia mau ana e pili ana i ke anawaena o ke kila hex (ana ʻia ma luna o nā pālahalaha) a me ka lōʻihi ma luna o ke kola paʻa. E holo mau ana ke kila nui ka nui o ka pahu ku'i, aka, he mea ma'amau ka loa'a 'ana o ka drill 55lb i ho'onohonoho 'ia no ka shank 7/8 x 3 ¼". Pono ʻoe e ʻike i ka hoʻonohonoho shank āu i loaʻa ai ma mua o ke kauoha ʻana i kāu kila drill.
KaʻAnuʻu Hana 2: E hoʻoholo i ka Drill a me ka Bit Configuration no kāu Rock Drill Shank
H Thread Steel and Bits:
ʻO H thread paha ka mea maʻamau i hoʻohana ʻia ma muli o kona maʻalahi a me ka loaʻa. ʻO ke kaula kāne ma ke kila ma kahi o 1" anawaena a ma kahi o 3/4" ka lōʻihi. Hoʻokomo pinepine ʻia ke kila mai ka 12" a hiki i ka 120" ka lōʻihi ma nā hoʻonohonoho 3 shank a pau. Aia nā ʻāpana mai ka 1 3/8" a hiki i ka 3" anawaena i ke keʻa carbide piha (maʻamau), 1 3/8" a i 2" ma ke keʻa pāpaʻu, 1 3/8" a i 2 1/4" ma ke pihi pihi bits a me 1 3/8 "a 2 -5/8" anawaena i loko o ka bit kila a pau.
Hana ʻia ke kila wiliwili H thread mai ke kila kalapona kiʻekiʻe. Hoʻohana pinepine ʻia, hana ʻia, a mālama ʻia ka wela e loaʻa i waho ke pale ʻana i ka ʻaʻahu me ka mālama ʻana i kahi kumu palupalu iki e mālama a hoʻololi i ka ikehu hopena. He kila hoʻokele poʻohiwi, ʻo ia hoʻi, ʻoi aku ka paʻa o ke kapa o ka bit a hiki i ka poʻohiwi i hana ʻia ma ke kila. Hoʻololi ʻia ka ikaika percussive ʻoiai ke kila a me ke kapa o ka bit i ke alo - e uhaʻi i ka mea i mua.
ʻOiai ʻo H thread steel ka mea maʻamau maʻamau - aia kona mau nāwaliwali. ʻO ke kaʻa poʻohiwi ka mea e hoʻopaʻa paʻa ka bit i ka poʻohiwi o ke kila. Inā wehe ʻia mai ka poʻohiwi - e hele ana nā pūʻali koa a pau i nā kaula liʻiliʻi ma ka bit a me ke kila - a e hāʻule koke lākou. E hoʻomau i ka hoʻohaʻahaʻa i lalo a mai ʻae i ka puʻu ʻana i loko o ka lua a pono e hana maikaʻi ke kaula H i ka nui o nā noi wili pōhaku paʻa.
ʻO kēia bit he 4 mau mea hoʻokomo carbide brazed kālā nui e paʻa maikaʻi loa i ka hana ʻana i nā noi wili pōhaku paʻa. Paʻa maikaʻi lākou ma laila a hiki ke hoʻomaʻamaʻa ʻia inā paʻa loa lākou i ka pono.
ʻOi aku ka liʻiliʻi o ke kumukūʻai ma mua o ka Full Carbide bit akā loaʻa kahi hapa o ka tungsten carbide insert. Hiki iā lākou ke "hoʻokele waiwai" i kekahi manawa. (nā hana liʻiliʻi, mea abrasive loa, wili ʻana i nā kūlana i hiki ke hāʻule ʻole)
ʻOi aku ke kumukūʻai o ke pihi pihi ma mua o ka ʻāpana kea Full Carbide. Loaʻa iā ia nā pihi carbide lehulehu i kaomi ʻia i ka maka o ka bit. Hiki i nā mīkini lima lima nui ke hāʻawi i ka ikehu hopena e hoʻonui i kēia mau ʻāpana ma mua o kahi ʻāpana keʻa i ka wikiwiki a me ka lōʻihi i nā kūlana kūpono.
Hoʻopili ʻia kēia mau ʻāpana keʻa a paʻakikī a ʻo ia nā koho liʻiliʻi loa. Me ka ʻole o ka ʻāpana carbide hiki iā ʻoe ke manaʻo i kahi ola pōkole ʻoi loa i nā kūlana abrasive.
Ua hoʻohana mua ʻia ke kila drill tapered i ka ʻeli ʻana ma lalo o ka honua ma nā pahu jackleg. ʻOi aku ka laha o ka taper 12 ma Kanada a ʻoi aku ka nui o ka 11 degere ma US a me Central America. Hoʻokomo ʻia ka bit tapered wahine i ke kila wili lipi kāne. Ma hope o ka male ʻana - hiki ke hoʻokaʻawale ʻia me ke kīkeke iki ke pau ka bit.
Ua apono kekahi poe hana aelike - e like me ka sthana ʻia ka puhi ma nā puke nui a maʻalahi ka hana ʻana no laila hiki ke emi ke kumu kūʻai. Eia naʻe, ua hana ʻia no ka hana ʻana i ka mining a ua kaupalena ʻia i ka laulā. ʻO 7/8 x 4 ¼ ka hoʻonohonoho maʻamau o ka drill steels a ua kaupalena ʻia ka laulā o nā bits. ʻO ka mālama ʻole ʻana i ke kaomi ʻana i lalo e hopena paha i ka nalowale ʻana o ka bit i loko o ka lua.
ʻO ke kila kaula a me nā ʻāpana:
ʻO 100 kaula (1” kaula, R25) a me 125 kaula (1 ¼” kaula, R32) hoʻohana nui ʻia i loko o nā noi eli ana. Ua huli ka nui o nā mea aelike i kēia ʻano kila no ka hoʻolōʻihi ʻana i ke ola, ʻoi aku ka nui o nā kūlana koi a i ʻole ke ʻeli mau ʻana i nā lua 2 ½” me ke anawaena. ʻO ke kila drill ka mea maʻamau i carburized kahi hana o ka hoʻokomo ʻana i ke kila me nā mea kalapona i loko o ka umu. Hāʻawi kēia i ke kila i kahi pahu paʻa loa i ka mālama ʻana i ka paʻakikī haʻahaʻa i loko e hoʻoneʻe i ka hawewe hopena. ʻOi aku ka nui/ʻoi aku ka lōʻihi o ke kaula a e iho i lalo i loko o ka ʻāpana pōhaku. ʻOi aku ka kala ʻana o kēia hui ʻana i nā kūlana wili paʻakikī. Hana ʻo Crowder Supply i nā ʻano like ʻole o ke kila a me nā mea hoʻololi bit no nā ʻoihana track nui akā ʻaʻole pono ka neʻe ʻana ma waho o kēia mau kaula ʻelua me nā wili lima.
Hāʻawi pū nā kaula kaula kaula iā ʻoe i ka hiki ke holo i nā kaula drill me ka hoʻohana ʻana i nā kila hoʻonui. Hāʻawi kēia iā ʻoe i ke koho e wili i kahi lua hohonu a i ʻole e wili i nā lua lōʻihi ma nā wahi paʻa.
E ʻoluʻolu e hoʻomaopopo iā mākou inā hiki iā mākou ke kōkua me kāu ʻoihana wili ʻana [email protected]
