1. Ikaika o ka Mea Hana: Hana Kūikawā no nā Hana Hana Kaumaha

ʻO CQC Track (HELI MACHINERY MANUFACTURING CO., LTD.) kahi mea hana OEM i hoʻohui ʻia a me ka mea hoʻolako ma hope o ka mākeke o nā ʻāpana undercarriage crawler kaumaha, me ke keʻena nui ma Quanzhou, Fujian Province, Kina. Mai ko mākou hoʻokumu ʻia ʻana i ka makahiki 2005, ua ulu mākou i loko o kahi ʻoihana e uhi ana ma mua o 60 mu, e hoʻohana ana ma mua o 200 mau limahana, a e hana ana ma mua o 200 mau mea hana mīkini CNC me nā lako hana hoʻoheheʻe, forging, a me ka hoʻomehana i hoʻohui ʻia. Uhi kā mākou papa hana huahana i nā ʻāpana undercarriage ma nā ʻāpana mīkini 1.5-ton a 300-ton holoʻokoʻa, i hoʻokō ʻia e ka nānā pono ʻana i nā hiʻohiʻona e ʻoi aku ana ma mua o 50 tons hana.

Ke hana nei kā mākou hale hana ma ke ʻano he kahua hana OEM i hōʻoia ʻia no ka ʻoihana lako kaumaha honua, e hoʻolako nei i nā ʻākoakoa track piha, nā rollers, nā idlers, a me nā sprockets iā Hitachi, Kobelco, LiuGong, XCMG, a me SDLG, a me ka lawelawe ʻana ma ke ʻano he hoa OEM a me ODM no nā hoʻonā undercarriage e kūpono iā Caterpillar. ʻO kēia ʻoiaʻiʻo OEM i hoʻokomo ʻia ʻo ia hoʻi ka CATERPILLAR 399-5056 Lower Roller Assembly i hana ʻia ma nā mīkini paʻi forging like, nā umu mālama wela, a me nā kikowaena mīkini CNC e lawelawe ana i nā laina ʻākoakoa o kēia mau mea hana. ʻO nā palapala hōʻoia mea, nā kaohi hana, a me ka gating maikaʻi hope loa i hoʻopili ʻia i kēia roller ʻo ia nā mea i kauoha ʻia e nā mea hana lako paʻakikī loa o ka honua. Ua hōʻoia ʻia kā mākou ʻōnaehana hoʻokele maikaʻi i ka ISO 9001:2015 a me IATF 16949, me ka nānā ʻana i ka SPC manawa maoli no ka hoʻomanawanui bore, ka mamao pitch, a me ke kūpaʻa mālama wela, a me Cpk ≥ 1.67.

ʻO ke koʻikoʻi, maopopo iā CQC Track he nui nā koi o nā wili lua pahū rotary a me nā mea ʻeli mining nui ma mua o nā mīkini kūkulu maʻamau. ʻAʻole e like me nā mea ʻeli e hana ana ma ka ʻāina i hoʻomākaukau ʻia, pono nā wili lua pahū e hele ma luna o ka pōhaku haki, nā ʻoki wili, a me nā noho like ʻole me ka hāpai ʻana i ke kaumaha nui o ke kia, ke poʻo rotary, a me ka compressor ma luna o ka moku. Ua hana ʻia kā mākou mau wili ala kaumaha me kēia mau kūlana i ka noʻonoʻo, e hoʻokomo ana i nā ʻōnaehana sila i hoʻonui ʻia a me nā kikoʻī mea i hoʻoponopono ʻia no ka hoʻopili ʻōwili ukana kiʻekiʻe mau.

2. Hoʻolālā ʻenehana: Hoʻoheheʻe ʻia, mālama ʻia i ka wela, a sila ʻia no ka hana koʻikoʻi

Pono kahi wili haʻahaʻa ma kahi ʻeli papa 50-tona a i ʻole ka wili puka pahū rotary e hoʻohui i ka kūpaʻa kūkulu nui me kahi ʻano sila impermeable a me kahi hehi kūpaʻa loa i ka ʻaʻahu. Kūkulu ʻia ka CQC Track 399-5056 Lower Roller Assembly ma o kahi kaʻina hana i kāohi pono ʻia a kiʻekiʻe.

Hoʻomehana ʻia nā billet i 1150–1180 °C a ua hoʻokau ʻia i ka forging wela i kāohi ʻia me ka ratio deformation ≥ 3:1, e hoʻohālikelike ana i ke kahe ʻana o ka palaoa kūloko a puni ke axis amo. Hoʻopau kēia kaʻina hana forging i ka porosity kūloko, nā lua, a me nā microstructural inconsistencies i loko o nā koho hoʻolei ʻē aʻe, e hāʻawi ana i kahi ʻano monolithic me ke kūpaʻa kūikawā a kūlike i ka luhi rolling-contact, spalling, a me ka haki ʻana o ka hopena. ʻO nā koho mea maʻamau o ka ʻoihana no kēia noi e pili ana i nā alloys paʻakikī kiʻekiʻe e like me 40Mn2, i koho kūikawā ʻia no ko lākou kaulike o ka paʻakikī o ke kumu a me ka paʻakikī o ka ʻili. Ua hōʻoia ʻia ke kaʻina hana forging me ka hoʻāʻo ultrasonic a me ka nānā ʻana i ke kahe ʻana o ka palaoa ma nā laʻana ʻoki e hōʻoia i ka pono o loko.

Nā Uhi ʻAoʻao Hao Hoʻolei Spheroidal Graphite (Hao Ductile, Ball-Milled Casting): Hana ʻia nā uhi ʻaoʻao sila ma o ke kaʻina hana hoʻolei graphite spheroidal pololei (hao ductile). Ua koho ʻia kēia mea no kona machinability maikaʻi loa, kūpaʻa dimensional kiʻekiʻe, a me ka hiki ke hāʻawi i kahi ʻili paʻa a palupalu no ka ʻōnaehana sila, e hōʻoiaʻiʻo ana i ka hoʻopili like ʻana o ka sila a me ka pono piha ʻole o ka leak ma luna o ke ola lawelawe holoʻokoʻa o ka roller.

ʻO ke koʻokoʻo me nā Grooves Sila ʻElua a me ka ʻōnaehana Sila ʻAila Lana Kiʻekiʻe: Ua wili ʻia ke koʻokoʻo paʻa me kahi ʻano groove sila ʻelua kikoʻī, e hana ana i kahi labyrinth o loko e hoʻokipa ai i kahi sila ʻaila lana duo-cone kiʻekiʻe. ʻO kēia ʻenehana sila metala maka-a-maka—i ʻike ʻia hoʻi he sila lana, sila duo-cone, a i ʻole sila ola—ʻo ia ka pae hoʻohālikelike honua no ka hoʻokaʻawale loa ʻana i ka wai, ka lepo, ka lepo silica maikaʻi, a me ka slurry abrasive mai ka lua bearing o loko. Ua hoʻolālā ʻia kēia mau sila e pale i nā ʻāpana ma lalo ma ka mālama ʻana i nā ʻōpala a me ka pale ʻana i ka leakage o nā lubricants pale. Ua hoʻopiha ʻia ka lua i sila piha ʻia me kahi grease anti-freeze kū i ka mahana haʻahaʻa i hana kūikawā ʻia, e hōʻoiaʻiʻo ana i ka lubrication piha piha i kēlā me kēia hoʻomaka a me ka pale ʻana i ka corrosion mau mai ka Arctic deep-freeze a i ka tropical monsoonal humidity.

Kaʻina Hana Hoʻomaʻamaʻa Wela Kiʻekiʻe:

Hoʻopau a me ka Hoʻomanawanui Hoʻohui: Hoʻomaʻamaʻa mua ʻia ke kino huila i hana ʻia i kahi pōʻaiapuni hoʻopau a me ka hoʻomanawanui ikaika. Hoʻomaʻemaʻe like kēia mālama wela hoʻohui i ka microstructure kumu i loko o ka martensite hoʻomanawanui, e hāʻawi ana i kahi hui kūpono o ka ikaika tensile kiʻekiʻe a me ka paʻakikī koʻikoʻi ma kēlā me kēia pūʻulu hana.

Ka Mīkini ʻAʻole Kūpono a Hoʻopau: Ma hope o ka hoʻomaʻemaʻe wela, hana ʻia ka mīkini ʻaʻole kūpono i ka mīkini kokoke i ka geometry net, a ukali ʻia e ka mīkini hoʻopau CNC e hoʻokō i nā ʻae ʻana o ka CATERPILLAR OEM pololei, me ke anawaena hehi 200 mm a me nā kikoʻī laulā kau ʻana 299.2 mm no ka 399-5056.

Hoʻopaʻakikī Induction (55–62 HRC): Hoʻopaʻakikī koho ʻia nā ʻaoʻao o ke kaula wili a me ka flange ma o ke kaʻina hana hoʻopaʻakikī induction alapine waena i kāohi ʻia. Hoʻokumu kēia i kahi hihia hohonu, kūpaʻa i ke kapa me ka paʻakikī o ka ʻili i mālama mau ʻia ma waena o 55 a me 62 HRC, me nā hohonu o ka hihia o 2.0–3.2 mm. Kūʻē nui ka hihia paʻakikī i ka grooving abrasive, ka deformation plastic, a me ka spalling i hoʻomaka ʻia e ka ʻili, e hoʻonui nui ana i ke kūpaʻa ʻana i ke kapa i loko o ke kaiapuni ʻino a me ka abrasion kiʻekiʻe o ka hana ʻeli pōhaku paʻakikī a me ka hana aggregate. Ke hoʻomau nei ka ductile, tempered core ma lalo o ka papa paʻakikī i ka omo ʻana i ka hopena ikaika me ka ʻole o ka laha ʻana o ka māwae. Hōʻoia kēia ʻenekinia thermal piha i ka lōʻihi loa a me ke kūʻē ʻana i ka deformation, ʻoiai ma nā noi koʻikoʻi loa.

3. ʻElua mau makahiki o ka hoʻomaʻemaʻe mau ʻana i ke kaʻina hana, i hōʻoia ʻia ma nā kūlana koʻikoʻi o ka honua

ʻO ka CQC Track 399-5056 Lower Roller Assembly ka huahana pololei o kahi pōʻaiapuni hoʻomaikaʻi ʻenekinia mau he 20 mau makahiki, i hoʻokele piha ʻia e ka loiloi ʻano hemahema a me ka ʻikepili ʻaʻahu i hōʻiliʻili ʻia mai nā wahi hoʻokaʻawale a me ke kūkulu ʻana koi nui loa o ka honua. Ua hoʻāʻo ʻia kā mākou mau wili haʻahaʻa, kālailai ʻia, a hoʻomaʻemaʻe iki ʻia ma o ka hana mau ʻana ma nā lua gula a me platinum hohonu o ʻApelika Hema, nā lua keleawe a me ke kālā kiʻekiʻe o Peru a me Ecuador, nā kīʻaha hao hao hau o Rusia, nā wahi lua pōhaku paʻakikī abrasive a me nā wahi wāwahi o Korea Hema, nā papahana ʻoihana nui a me nā papahana mining o India, a me nā hana laterite a me basalt tropical o Vietnam. ʻO kēlā me kēia palena hoʻolālā - mai ka hoʻonui ʻana i ke kiʻikuhi tempering e hoʻopau i nā koina koʻikoʻi koena, a hiki i ka hoʻoponopono pololei ʻana i ka wikiwiki scan hardening induction no kahi gradient paʻakikī kīnā ʻole, a hiki i ka hōʻoia ʻana i ka pumpability lōʻihi o ka grease anti-freeze ma waena o nā loli mahana koʻikoʻi - ua hana pololei ʻia i loko o kā mākou kūlana hana. ʻO ke kūpaʻa maikaʻi a me ka hilinaʻi hana o ka wili haʻahaʻa o kēia lā ʻaʻole ia he mau ʻōlelo hoʻohiki papa inoa; he mau ʻano i hōʻoia ʻia e ke kahua i hōʻoia ʻia ma luna o nā miliona o nā hola hana mīkini ma kēlā me kēia ʻāina. Hoʻokō kā mākou kaʻina hana i ka 100% traceability mai ka mea maka a i ka huahana i hoʻopau ʻia, me ka nānā ʻana i ka batch MES a me nā code QR e hoʻopili ana i ka forging, machining, ka mālama wela, a me nā moʻolelo uhi.

4. He ʻōnaehana ʻāpana Undercarriage piha a kūlike me ke kākoʻo hoʻopilikino

ʻAʻole hana kaʻawale kahi wili haʻahaʻa. ʻO ka hoʻokomo ʻana i kahi wili lalo kiʻekiʻe me nā kaulahao track i hoʻohana ʻia, nā wili luna marginal, a i ʻole kahi idler luhi e hana i kahi kūlike ʻole pipiʻi i ke ola ʻāpana e hoʻolalelale i ka hōʻino ʻana o ka undercarriage holoʻokoʻa. Ma ke ʻano he mea hana kūikawā o nā ʻāpana undercarriage piha no nā wili hoʻoheheʻe rotary blast-hole kaumaha a me nā mea ʻeli kolo, hoʻopau ʻo CQC Track i kēia pilikia ma ka hana ʻana i kahi suite piha o nā ʻāpana undercarriage pili no ka CATERPILLAR CAT349, CAT352, CAT355 DF, a me ka moʻo ākea 345/349/352/355. Hoʻokomo pū kā mākou papahana hana i nā ʻākoakoa loulou track i kūlike me nā pine a me nā bushings i hoʻopaʻa ʻia i ka induction, nā ʻākoakoa huila idler mua (572-1653,561-8970), nā wili lawe luna (300-4610), a me nā ʻākoakoa sprocket hoʻokele hope loa (), i hana ʻia i loko o kahi envelope hana metallurgical a me ka thermal i hoʻohui ʻia.

Eia kekahi, kākoʻo ikaika kā mākou hui ʻenekinia i ka hoʻopilikino ʻana maʻamau ʻole no nā hoʻonohonoho mīkini kūikawā, nā pani ʻāpana kahiko, a i ʻole nā ​​​​hoʻololi kikoʻī no ka noi. Ma ke ʻano he loea hoʻopilikino maʻamau ʻole, hana kā mākou hui i ka ʻenekinia hoʻohuli a me ka nānā ʻana i nā mea palena ʻole e hāʻawi i nā hoʻonā bespoke no nā hana mining kūikawā, ululāʻau, a me nā noi kiʻekiʻe. ʻO nā hāʻawi maʻamau ʻole e pili ana i nā ana o ke koʻokoʻo a i ʻole ka flange i hoʻololi ʻia, nā ʻano bolt-hole i hoʻololi ʻia, nā uhi ʻili kūikawā, a me nā ʻano paʻakikī i hana ʻia. Ua hoʻonohonoho ʻia ka hui ʻoihana CQC International—ʻo Philip, Jack, a me Haily—e hāʻawi i kēia mau ʻāpana ma ke ʻano he hoʻouna i hoʻonohonoho ʻia, e pili ana i nā kit a e hoʻokele i nā papahana maʻamau mai ka loiloi loea mua a hiki i ka hoʻouna honua hope loa.

5. Hoʻolako Pololei Honua i nā Mākeke Mining a me ke Kūkulu ʻana e Noʻonoʻo Ana i ka Kūlana Kiʻekiʻe

Hoʻolako pololei ʻia nā ʻāpana undercarriage kaumaha CQC Track a hoʻokuʻu ʻia aku me ka hilinaʻi piha i nā mākeke e hoʻokō ana i nā kūlana maikaʻi a me ka hana hoʻokomo paʻa loa. Ke kākoʻo ikaika nei kā mākou mau ʻaha huila haʻahaʻa CATERPILLAR 349/352/355 DF a me nā pahu undercarriage piha i nā ʻauwaʻa excavator a me nā ʻauwaʻa blast-hole ma ʻAmelika Hema (Ecuador, Peru), ʻApelika Hema, ka Russian Federation, Korea Hema, a me nā ʻāpana noi kiʻekiʻe ma India. Hoʻonui hou aku kā mākou pūnaewele hoʻolako pololei honua i nā lāhui mokupuni o ka Pākīpika Hema, Vietnam, Kazakhstan a me ke alaloa ākea o ʻAsia Waena, Turkey, a me ʻAmelika ʻĀkau. Mālama ʻo CQC Track i kahi pūnaewele hoʻolako honua me ka lawe wikiwiki ʻana i ʻAmelika ʻĀkau, ʻEulopa, ʻApelika, a me Asia Hikina Hema ma o nā hoa logistics hilinaʻi, a ke ʻimi nei i nā mea kūʻai aku, nā mea hoʻolaha, a me nā mea hoʻolako lako hana kūkulu e hoʻonui i kona hiki honua. ʻO kēia ʻae mau ʻia a laha ʻia ma ka honua holoʻokoʻa—e uhi ana i ka wela equatorial, ka lepo maloʻo o ka wao nahele, a me nā kūlana hau hohonu o ka ʻāina—e hōʻoia ana i ka hana hou ʻana o CQC Track i ka wela, ka pololei o ka dimensional, ka hoʻopilikino anti-corrosion, a me ka pane ʻana i ka hoʻopilikino ʻana e hoʻokō i nā koi honua o ka mīkini ʻeli papa 50-tonne a me nā mākeke ʻeli wili pahū rotary ma ka honua holoʻokoʻa.

Ke kuhikuhi ʻoe i kahi CQC Track 399-5056 Track Lower Roller Assembly no kāu CATERPILLAR CAT349, CAT352, a i ʻole CAT355 DF—a i ʻole e hoʻopili mai iā mākou no kahi hopena undercarriage maʻamau no kāu wili hole pahū rotary—ke hoʻokomo nei ʻoe i kahi ʻāpana i hana ʻia i loko o ka ʻōnaehana OEM like e hoʻolako ana i nā lama lako kaumaha alakaʻi o ka honua. Mai kā mākou hale hana pololei a i kāu kahua eli a i ʻole papahana kūkulu, hōʻike kēia wili i kahi kūpaʻa ʻenekinia 20 makahiki e mālama i nā lako hana kaumaha i hoʻohana ʻia, hoʻololi ma hope o ka hoʻololi koi.

Ua kākau ʻia kēia ʻatikala e Jack o ka CQC International Business Team, me ka mahalo nui iā Philip lāua ʻo Haily no kā lāua kākoʻo hoʻolaʻa ʻana i kā mākou mea kūʻai honua CATERPILLAR undercarriage a me ka rotary blast-hole drill.
