Ka Ikepili o na Koina Hana Koko no na Kui Kabide Cemented

ʻO ka carbide chisel i hoʻopaʻa ʻia ka puʻuwai o nā mea hana wili pōhaku hou, a ʻo kāna hana e hoʻoholo pololei i ka pono o ka wili ʻana a me ke ola mea hana. No ke koho ʻepekema a hoʻohana i kēia mau chisels, pono e hoʻomaopopo hohonu i nā ʻāpana hana kumu.

1. Paʻakiki: ʻO ka hōʻailona mua o ke kū'ē i ke komoʻana a me ka lole

ʻO ka paʻakikī kahi ʻāpana e ana i ka hiki o ka ʻili o ka carbide chisel i hoʻopaʻa ʻia e pale aku i ke komo ʻana a i ʻole ke ʻoki ʻia e nā mea ʻē, i hōʻike pinepine ʻia ma Rockwell Hardness (HRA). Hoʻoholo nui ʻia e ka paʻakikī, ka nui o ka palaoa, a me ka hāʻawi ʻana i ka tungsten carbide (WC) i loko o ka mea. ʻO ka paʻakikī kiʻekiʻe, hiki i ka chisel ke nahu maikaʻi i ka pōhaku paʻa a pale aku i ka ʻaʻahu abrasive mai nā ʻokiʻoki pōhaku, no laila e mālama ai i kahi ʻoi a hoʻolōʻihi i ke ola lawelawe. I loko o nā pōhaku abrasive loa, ʻo ka paʻakikī ka mea koho mua.

2. 'O'ole'a: 'O ka 'oia'i'o nui e kū'ē i ka hopena a me ka ha'iha'i

'O ka 'o'ole'a 'o ia ka hiki 'ana o ka mea waiwai ke komo i ka ikehu me ka haki 'ole. ʻO ka wili ʻana he kaʻina hana hopena kiʻekiʻe-nui. Inā ʻaʻole lawa ka paʻakikī o ka chisel, ʻoi aku ka maʻalahi o ka ʻoki ʻana, ka pohā, a i ʻole ka pau ʻole. ʻO ka paʻakikī e pili ana i ka ʻike a me ka hāʻawi ʻana i ka māhele hoʻopili cobalt (Co). ʻO ka maʻamau, ʻoi aku ka nui o ka cobalt maʻi i ka ʻoi aku ka paʻakikī. Ma nā ʻano pōhaku ʻāhaʻi a me nā ʻano like ʻole, ʻo ka paʻakikī kiʻekiʻe ke ala ola e pale ai i ka hāʻule ʻole o ka chisel.

3. ʻO ka ikaika hoʻololi: ke ana o ka hiki ke amo

ʻO ka ikaika flexural ke koʻikoʻi kiʻekiʻe e hiki ai i kahi mea ke kū ma mua o ka haki ʻana ma lalo o kahi haʻahaʻa piʻo. Hōʻike piha ia i ka "ikaika" a me ka "paʻakikī" o ka carbide i hoʻopaʻa ʻia a pili pono i ka hiki o ka chisel ke pale aku i ka haki ʻana ma lalo o nā mana hopena nui a me nā manawa paʻakikī. ʻO ke kui me ka ikaika flexural kiʻekiʻe e like me ka loaʻa ʻana o ka "iwi kuamoʻo," e hiki ai iā ia ke hoʻomanawanui i nā pilikia like ʻole i loaʻa i nā kūlana hana koʻikoʻi a me ka hōʻoia ʻana i ka palekana a me ka hilinaʻi.

4. Paʻa Paʻa: ʻO ke kū'ē i ka hoʻolaha ʻana i ka māwae

ʻO ka paʻakikī haʻihaʻi he hōʻailona kiʻekiʻe loa o ka paʻakikī, e pili ana i ka hiki o kahi mea i loaʻa nā micro-cracks e pale aku i ka hoʻolaha ʻana o ka māwae paʻa ʻole. Ma ka hana pono, hiki ʻole ke ʻalo ʻia nā hemahema microscopic i loko o ka mea. ʻO ka paʻakikī o ka haʻihaʻi kiʻekiʻe, ʻoiai inā e ulu ana nā micro-cracks, ʻaʻole paha lākou e hoʻolaha wikiwiki a hoʻokō i ka hemahema. He mea koʻikoʻi kēia ʻāpana no ka hōʻoia ʻana i ka palekana o ka hāmeʻa ma lalo o nā kūlana koʻikoʻi e pili ana i nā ukana eccentric (e.g., bit slippage).

Ka hopena: ʻO ke kaulike a me ka Synergy o nā waiwai

He mea nui e hoʻokūpaʻa ʻaʻole i noho kaʻawale kēia mau ʻāpana koʻikoʻi akā pili pili a pili pinepine i nā kālepa. ʻO ka ʻimi ʻana i ka paʻakikī kiʻekiʻe loa e hele pinepine mai i ke kumukūʻai o ka hoʻemi ʻana i ka paʻakikī a me ka ikaika, a ʻo ia hoʻi. No ka laʻana, hōʻike nā chisels me nā kīʻaha maikaʻi a me nā ʻiʻo kobalt haʻahaʻa i ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana akā ʻoi aku ka paʻakikī. ʻO ka mea ʻē aʻe, ʻoi aku ka ʻoi aku o ka ʻoi aku ka ikaika a me ka ikaika akā ʻoi aku ka ʻoi aku o ka paʻakikī.

No laila, ʻo ke koho ʻana i kahi chisel carbide cemented ʻaʻole ia e pili ana i ka ʻimi ʻana i ka mea hope loa i kahi ʻāpana hoʻokahi. Akā, e pili ana i ka loaʻa ʻana o ka pae kaulike maikaʻi loa ma waena o ka paʻakikī, ka paʻakikī, a me ka ikaika e pili ana i nā kūlana o ka hoʻokumu ʻia ʻana o ka pōhaku (e like me ka paʻakikī a paʻa paha a i ʻole nā ​​​​haʻi a paʻakikī). Loaʻa kēia ala i ke ola lawelawe lōʻihi a me ka hana kiʻekiʻe.
