Mphamvu yokoka yokhazikika yopangira makina opanga fakitale imafuna zambiri kuposa zitsulo zosungunuka ndi zitsulo. Amafunikira kuwongolera bwino kwamafuta, kasamalidwe ka nkhungu kobwerezabwereza, komanso kuwongolera zitsulo —makamaka popanga zida zodalirika kwambiri zamapampu amadzimadzi, mavavu akumunda wamafuta, kapena makina owongolera magalimoto. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera magawo opitilira 12,000 achitsulo ndi chitsulo m'mawunga okhazikika kuyambira 2018-ndipo kulephera kulikonse, kugwedezeka kulikonse, chochitika chilichonse chocheperako chinatiphunzitsa chinthu chimodzi: kuponyera mphamvu yokoka sikungothira chabe. Imayendetsedwa kulimbitsa.
Chifukwa Chake Permanent Mold Gravity Casting Imapambanabe Pamagawo Apakati-Volume Industrial
Akatswiri ena amaganiza kuti kuponya ndalama kumalowa m'malo mwa kuponya nkhungu kosatha. Koma popanga zenizeni - osati zolemba za labu - nkhungu yosatha imapereka kubwereza kokulirapo kwa nyumba ngati midadada ya silinda ya pampu ya piston ndi matupi okakamiza. Chifukwa chiyani? Chifukwa kutentha kwa nkhungu kumakhala mkati mwa ± 5 ° C kudutsa 300+ mizere mukamagwiritsa ntchito zitsulo zotenthedwa, zokutira H13 zida zachitsulo. Kuponya mchenga sikungafanane ndi kukhazikika kumeneko. Kuponyera ndalama kumayambitsa kusinthika kwa zipolopolo za ceramic komanso kupsinjika kwakukulu kotsalira. Timachiyeza: pa 420 mm × 280 mm × 120 mm kuponyera maziko, nkhungu yokhazikika imakhala ndi GD&T kulolerana kwa ± 0.15 mm pa mayunitsi 500; kuponya mchenga pafupifupi ± 0.32 mm, ndi 17% zidutswa chifukwa chapakati kusintha.
Timayendetsa mizere iwiri yokhazikika ya nkhungu yokoka—imodzi yachitsulo cha ductile iron (ASTM A), ina yachitsulo chotsika alloy (A105N). Zonse zimagwiritsa ntchito zitseko zothira pansi, zoyika zoziziritsa kukhosi m'magawo ovuta, komanso kuyang'anira nthawi yeniyeni ya thermocouple pamakoma a nkhungu. Palibe zongoyerekeza. Palibe nthawi yozungulira "yokhazikika". Gawo lirilonse liri ndi mbiri yake yolimba yomwe imayikidwa mumalipoti athu ovomerezeka.
Kumene Mafakitole Ambiri Amalephera—ndi Mmene Timawakonzera
Ntchito zambiri zamafakitale zopangira nkhungu zokhazikika zimagwera pamfundo zitatu: kuwonongeka kwa nkhungu, kutentha kosagwirizana, komanso kapangidwe kake kokwera kokwanira ka chakudya chamtundu wa aloyi. Tidawonera izi panyumba ya AMS 5387 cobalt alloy alloy. Mafilimu 19 oyambirira adawonetsa porosity yapansi panthaka pafupi ndi flange-ngakhale chemistry yabwino. Choyambitsa? Nkhungu pamwamba makutidwe ndi okosijeni pambuyo 42 mkombero kusintha kutentha m'zigawo mitengo. Yankho: tsopano tikukonzanso kuwombera 35 kulikonse pogwiritsa ntchito aluminium blasting ndi zokutira za borosilicate za mwini wake - zimatsimikiziridwa ndi kuyesa kwa infrared emissivity pamaso pa kuthira kulikonse.
Timakhazikitsanso malamulo okhwima a preheat. nkhungu zathu sizilowa m'ng'anjo yozizira. Amalowetsedwa pa 280 ° C kwa mphindi 90, kenako amadumphira ku 320 ° C ± 3 ° C ndikusunga kwa mphindi 45 - kuyeza pazigawo zitatu zakuya. Izo sizingakambirane. Lumphani, ndipo mumapeza ming'alu yowopsya kapena zolakwika muzinthu zozikidwa pa T800. Makasitomala omwe amapereka nkhungu zawo nthawi zambiri amanyalanyaza izi. Timawayesa Awo tisanavomereze.
Kuphatikizika Ndiko Ubwino Weniweni—Osati Kungoponya
Chowonadi champhamvu yokoka chokhazikika chopangira fakitale yankho sichiyima pakugwedeza. Zimapitirira kupyolera mu makina, chithandizo cha kutentha, ndi metrology - zonse pansi pa denga limodzi. Panyumba yathu ya Qingdao, nyumba yopangira silinda imasuntha molunjika kuchoka ku nkhungu kupita ku CNC ndikuyatsa Mazak Integrex i-200S. Palibe kuchedwa kwamayendedwe. Palibe kuwonongeka kwa kusamalira. Palibe coordinate system reset. Timabowola makina ovuta pamene kuponyera kudakali mkati mwa 50 ° C ya kutentha kwa solidus-kuchepetsa kupotoza ndi 40% poyerekeza ndi makina a kutentha kwa chipinda.
Kuphatikizika kwathu koyima kumakwirira zigawo zinayi: chiphaso cha zinthu (zotentha zonse zomwe zingapezeke kumalipoti oyesa mphero), kutsimikizira kwa njira (ndi radiographic ndi ultrasonic sampling pa ASME B16.34), machining mwatsatanetsatane (CMM-yotsimikizika ku ISO 2768-mK), ndi kuyezetsa kogwira ntchito (kuyesa kwa hydrostatic pressure mpaka 450 bar pa makonda). Ichi ndichifukwa chake ma roller athu a winch center shaft amagalimoto omwe amatuluka mumsewu waukulu amapeza zokolola 100% zongodutsa koyamba - ngakhale atapanga ma taper osakhazikika komanso malo osokonezedwa.
Kusankha Wokondedwa Wanu Sizinthu Zamtengo - Ndi Za Kuneneratu
Ngati pulojekiti yanu ikufuna fakitale yopangira nkhungu yokhazikika yomwe imatumiza nthawi yake, imakhala ndi GD&T popanda mkangano, ndikuyika ziwopsezo zakupanga zida zisanayambe-muyenera kulembedwa, osati zotsatsa. Funsani mafunso atatu awa musanasaine:
- Kodi mungandiwonetse mapaketi anu atatu omaliza a PPAP-kuphatikiza zipika zokonza nkhungu ndi ma chart a kutentha kwamkati?
- Kodi mumasanthula pa kutentha kulikonse, kapena pamabatchi ankhani yoyamba?
- Kuponya kukalephera NDT, kodi mumapereka lipoti lokonzekera - kapena kungobwerezanso?
Timachita zonse zitatu. Nthawi iliyonse. Dongosolo lathu la ISO 9001:2015-certified limayang'anira kuwombera kulikonse, zopangira zilizonse, malo aliwonse a CMM. Palibe kuchotserapo. Umu ndi momwe timathandizira makasitomala ku North America, Germany, ndi Singapore — osabweretsa mochedwa pamaoda apakati mu 2023.
Kuyang'ana m'tsogolo, tikukulitsa luso lathu lamphamvu yokoka losatha la fakitale yopangira nkhungu munjira zosakanizidwa: zotayira pafupi ndi ukonde zokhazikika zomalizidwa ndi mphero ya CNC yothandizidwa ndi laser ya cobalt-nickel alloys. Osati chifukwa ndi buku - koma chifukwa deta yam'munda ikuwonetsa kuti imadula mtengo wonse ndi 22% pazigawo zomwe zimafunikira ma geometry ovuta komanso kukana kuvala kwambiri. Precision si dipatimenti. Ndi ndandanda.
