Inā he microcosm o ke kaʻina hana hoʻomohala ʻenehana honua holoʻokoʻa kiʻekiʻe-wikiwiki ʻōwīwīwīwīwīwīwīwīwīwī, a laila hiki ke manaʻo ʻia ka hammer drill bit e like me ka mōʻaukala hanohano o ka ʻenekinia hana hou.
I ka makahiki 1914, ua hoʻomohala ʻo FEIN i ka hāmare pneumatic mua, i ka makahiki 1932, ua hoʻomohala ʻo Bosch i ka ʻōnaehana SDS hammer uila mua, a ma 1975, ua hoʻomohala ʻo Bosch lāua ʻo Hilti i ka ʻōnaehana SDS-Plus. ʻO nā hammer drill bits kekahi o nā mea hoʻohana nui loa i ka ʻenekinia kūkulu hale a me ka hoʻomaikaʻi ʻana i ka home.
No ka mea, hoʻopuka ka hammer drill bit i ka neʻe wikiwiki (ka hopena pinepine) ma ke ala o ke koʻokoʻo wili uila i ka wā e kaʻa ana, ʻaʻole pono ka ikaika lima e wili i nā lua i nā mea palupalu e like me ka sima a me ka pōhaku.
I mea e pale ai i ka paheʻe ʻana o ka bit drill mai ka pahu a lele paha i waho i ka wā o ka hoʻololi ʻana, ua hoʻolālā ʻia ka shank poepoe me ʻelua dimples. Ma muli o nā ʻāpana ʻelua i loko o ka drill bit, hiki ke hoʻonui i ka hammering kiʻekiʻe a hiki ke hoʻomaikaʻi ʻia ka hana hammering. No laila, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka hāmare me ka SDS shank drill bit ma mua o nā ʻano ʻano shanks ʻē aʻe. ʻO ka ʻōnaehana shank a me chuck holoʻokoʻa i hana ʻia no kēia kumu, kūpono loa ia no nā ʻāpana hammer drill e wili lua i ka pōhaku a me ke kaʻa.
ʻO ka ʻōnaehana hoʻokuʻu wikiwiki ʻo SDS ke ʻano hoʻohui maʻamau no nā pahu hammer drill bit i kēia lā. Hāʻawi ia i kahi ala wikiwiki, maʻalahi a palekana hoʻi e hoʻopili ai i ka drill bit.
ʻO ka pōmaikaʻi o SDS Plus ʻo ia ka hiki ke hoʻokuʻu wale ʻia ka drill bit i loko o ka pūnāwai puna me ka ʻole o ka paʻa. ʻAʻole paʻa paʻa, akā hiki ke paheʻe i hope a i waho e like me ka piston.
Eia nō naʻe, he mau palena nō ka SDS-Plus. ʻO 10mm ke anawaena o ka SDS-Plus shank. ʻAʻohe pilikia i ka wā e wili ai i nā lua liʻiliʻi a me nā lua, akā i ka wā e hālāwai ai me nā lua nui a hohonu, ʻaʻole lawa ka torque, e hoʻopaʻa ai ka puʻupuʻu i ka wā o ka hana a haki ka shank.
No laila ma muli o SDS-Plus, ua hoʻomohala hou ʻo BOSCH i ka SDS-MAX ʻekolu a me ʻelua. ʻElima mau ʻōpuʻu ma ka lima SDS Max: ʻekolu mau ʻāwī hāmama a ʻelua mau ʻāwī paʻa (no ka pale ʻana i ka pahu drill mai ka lele ʻana mai ka pahu), ʻo ia ka mea maʻamau i kapa ʻia he ʻekolu-slot a me ʻelua-slot round hand, i kapa ʻia hoʻi he lima-slot round hand. ʻO ke anawaena o ke kumu a hiki i 18mm. Hoʻohālikelike ʻia me SDS-Plus, ʻoi aku ka maikaʻi o ka hoʻolālā ʻana o ka lima SDS Max no nā hiʻohiʻona hana koʻikoʻi, no laila ʻoi aku ka ikaika o ka torque o ka lima SDS Max ma mua o ka SDS-Plus, kahi kūpono no nā hammer drills nui no nā hana nui a hohonu.
Manaʻo ka poʻe he nui ua hoʻolālā ʻia ka ʻōnaehana SDS Max e pani i ka ʻōnaehana SDS kahiko. ʻO ka ʻoiaʻiʻo, ʻo ka hoʻomaikaʻi nui ʻana o kēia ʻōnaehana ʻo ia ka hāʻawi ʻana i ka piston i kahi hahau nui aʻe, i ka wā e paʻi ai ka piston i ka drill bit, ʻoi aku ka ikaika o ka hopena a ʻoi aku ka maikaʻi o ka ʻoki ʻana o ka drill bit. ʻOiai he hoʻomaikaʻi ia ma ka ʻōnaehana SDS, ʻaʻole e hoʻopau ʻia ka ʻōnaehana SDS-Plus. ʻOi aku ke kumukūʻai o ke anawaena lima 18mm o SDS-MAX i ka wā e hana ana i nā ʻāpana drill liʻiliʻi. ʻAʻole hiki ke ʻōlelo ʻia he pani no SDS-Plus, akā he mea hoʻohui ma kēia kumu.
ʻO SDS-plus ka mea maʻamau ma ka mākeke a kūpono ia no nā hammer drill me kahi drill bit anawaena o 4mm a 30mm (5/32 iniha a 1-1/4 iniha), ʻo ka lōʻihi pōkole loa ma kahi o 110mm, a ʻo ka lōʻihi loa ʻaʻole i ʻoi aku ma mua o 1500mm.
Hoʻohana pinepine ʻia ʻo SDS-MAX no nā lua nui a me nā koho uila. ʻO ka nui o ka hammer drill bit he 1/2 iniha (13mm) a 1-3/4 iniha (44mm), a ʻo ka lōʻihi holoʻokoʻa he 12 a 21 iniha (300 a 530mm).
Mahele 2: Kookoo wili
ʻAno maʻamau
Hana ʻia ke koʻokoʻo me ke kila kalapona, a i ʻole ke kila kila 40Cr, 42CrMo, a pēlā aku. ʻO ka hapa nui o nā hammer drill bits ma ka mākeke e hoʻohana i ke ʻano spiral i ke ʻano o ka drill twist. Ua hoʻolālā mua ʻia ke ʻano groove no ka wehe ʻana i ka chip maʻalahi.
Ma hope mai, ʻike ka poʻe ʻaʻole hiki i nā ʻano groove ʻokoʻa ke hoʻonui i ka wehe ʻana i ka chip, akā e hoʻolōʻihi i ke ola o ka drill bit. No ka laʻana, loaʻa i kekahi mau puʻupuʻu puʻupuʻu ʻelua i kahi pahi hoʻohemo chip i loko o ke awāwa. ʻOiai e hoʻomaʻemaʻe ana i nā chips, hiki iā lākou ke hana i ka wehe ʻana i nā ʻōpala lua, pale i ke kino drill, hoʻomaikaʻi maikaʻi, hoʻemi i ka hoʻomehana poʻo drill, a hoʻonui i ke ola o ka drill bit.
ʻAno hoʻoheheʻe lepo ʻole
Ma nā ʻāina i kūkulu ʻia e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa, ʻo ka hoʻohana ʻana i nā hoʻomaʻamaʻa hopena e pili ana i nā wahi hana lepo kiʻekiʻe a me nā ʻoihana kiʻekiʻe. ʻAʻole ʻo ka hoʻokō ʻana i ka ʻeli ka pahuhopu wale nō. ʻO ke kī ʻo ka wili pololei ʻana i nā lua ma nā wahi e kū nei a pale i ka hanu o nā limahana. No laila, aia kahi koi no nā hana lepo ʻole. Ma lalo o kēia koi, ua hoʻokumu ʻia nā puʻupuʻu lepo lepo ʻole.
ʻAʻohe spiral i ke kino holoʻokoʻa o ka bit drill me ka lepo ʻole. Wehe ʻia ka lua ma ka bit drill, a ʻo ka lepo a pau o ka lua waena e omo ʻia e kahi mea hoʻomaʻemaʻe. Eia nō naʻe, pono ka mea hoʻomaʻemaʻe a me ka paipu i ka wā o ka hana. Ma Kina, kahi i ʻike ʻole ʻia ai ka palekana pilikino a me ka palekana, pani nā limahana i ko lākou mau maka a paʻa i ko lākou hanu no kekahi mau minuke. ʻAʻole paha e loaʻa kahi mākeke ma Kina i kēia ʻano o ka lepo lepo ʻole i ka wā pōkole.
MAHELE 3: Lahi
Hana ʻia ke poʻo me ka YG6 a i ʻole YG8 a i ʻole ke kiʻekiʻe kiʻekiʻe cemented carbide, i hoʻokomo ʻia ma ke kino e ka brazing. Nui nā mea hana i hoʻololi i ke kaʻina hana hoʻoheheʻe mai ka wili manual kumu i ka wili ʻakomi.
Ua hoʻomaka kekahi mau mea hana me ka ʻokiʻoki, ke poʻo anu, ka lawelawe ʻana i ka hana hoʻokahi manawa, nā ʻāpana wili ʻakomi, hoʻoheheʻe ʻakomi, ʻo ia mau mea a pau i loaʻa i ka automation piha. Hoʻohana ʻia nā ʻōkuhi 7 a Bosch i ka hoʻoheheʻe ʻana ma waena o ka lau a me ke koʻokoʻo drill. Eia hou, lawe ʻia ke ola a me ka pono o ka drill bit i kahi kiʻekiʻe hou. Hiki ke hoʻokō ʻia nā pono maʻamau no nā wili hammer drill e nā hale hana carbide maʻamau. Hoʻokahi ʻaoʻao nā ʻaoʻao drill maʻamau. I mea e hoʻokō ai i nā pilikia o ka pono a me ka pololei, ʻoi aku ka nui o nā mea hana a me nā hōʻailona i hoʻomohala i nā drills multi-edged, e like me "cross blade", "herringbone blade", "multi-edged blade", etc.
ʻO ka moʻolelo hoʻomohala o nā hammer drills ma Kina
Aia ke kahua hoʻoheheʻe hāmare honua ma Kina
ʻAʻole kēia ʻōlelo he inoa hoʻopunipuni. ʻOiai aia nā hammer drill ma nā wahi a pau o Kina, aia kekahi mau hale hana hammer drill ma luna o kekahi pālākiō ma Danyang, Jiangsu, Ningbo, Zhejiang, Shaodong, Hunan, Jiangxi a me nā wahi ʻē aʻe. Aia ʻo Eurocut ma Danyang a he 127 mau limahana i kēia manawa, e uhi ana i kahi ʻāpana o 1,100 square square, a he nui nā lako hana. Loaʻa i ka hui ka ikaika ʻepekema a me ka ʻenehana, ʻenehana holomua, nā lako hana maikaʻi loa, a me ka mana koʻikoʻi. Hana ʻia nā huahana o ka hui e like me nā kūlana Kelemania a me ʻAmelika. He kūlana maikaʻi loa nā huahana āpau a mahalo nui ʻia ma nā mākeke like ʻole a puni ka honua. Hiki ke hāʻawi ʻia ʻo OEM a me ODM. ʻO kā mākou huahana nui no ka metala, kaʻa a me ka lāʻau, e like me ka Hss drill bits, SDs drill bits, Maonry drill bits, wod dhil drill bits, glass and tile drill bits, TcT saw blades, diamond saw blades, oscillating saw blades, bi-metal hole saws, diamond hole saws, TcT hollow saws, hole saws, hole a me ka pahi. ke hana ikaika nei mākou e hoʻomohala i nā huahana hou e hoʻokō i nā pono like ʻole.
