Aia ma Kina ke kahua hammer drill o ka honua

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 (i mea e pale ai i ka lele ʻana o ka puʻupuʻu mai loko mai o ka pahu), ʻo ia ka mea a mākou e kapa pinepine ai he ʻekolu-slot a me ʻelua-slot round hand. i kapa ʻia hoʻi he lima pōʻai lima. ʻO ke anawaena o ke kumu a hiki i 18mm. Ke 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 ka nui. a me na hana lua 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 he 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 me ka ʻaʻole iʻoi aku ka lōʻihi 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 ma Kina ke kahua hammer drill o ka honua

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 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- saws lua metala, saws puka daimana, saws hole TcT, saws hollow hammered a me saws hole Hss, etc. ke hana ikaika nei mākou e hoʻomohala i nā huahana hou e hoʻokō i nā pono like ʻole.
