Akatswiri akamatchula zitsulo zosapanga dzimbiri zoponyera mchenga wa mavavu othamanga kwambiri a hydraulic kapena nyumba zapampu zam'mphepete mwa nyanja, samangosankha zakuthupi - akubetcherana pa kukhazikika kwa dimensional, kukana dzimbiri, komanso kusasinthika kwapang'onopang'ono pansi pa kupsinjika kwenikweni kwamatenthedwe ndi makina. Chifukwa chake kusankha koyenera zitsulo zosapanga dzimbiri zoponya mchenga fakitale nkhani zambiri kuposa kutchula kulolerana papepala. Tawona mapulojekiti ambiri akuchedwa-osati chifukwa cha zolakwika zamapangidwe, koma ndi zoyambitsa zomwe zimayesa kuponya mchenga ngati chinthu chamtengo wapatali osati zitsulo.
Kuponyera mchenga kwachitsulo chosapanga dzimbiri sikuli ngati chitsulo chotuwa kapena aluminiyamu. Malo ake osungunuka kwambiri (1400-1500 ° C), kukhudzika kwa kuzizira, komanso chizolowezi chosankhana mitundu yosiyanasiyana chimafuna kuwongolera molimba kutulutsa kwa nkhungu, chemistry yomangirira, kutentha kothira, ndi nthawi yogwedeza. Kupatuka kwa 2 ° C mu preheat kungayambitse microporosity mu ASTM A351 CF8M mavavu matupi. Kusagwirizana kwa mamilimita 0.3 pamalunidwe apakati kumatha kusokoneza kutsekeka kwa silinda yapampu ya piston yomwe idavotera mipiringidzo 350. Izi sizowopsa zongoyerekeza. Ndi zolephera zomwe tazipeza m'magawo atatu aku North America opangira mafuta - chilichonse chimachokera kumagulu osagwirizana ndi tirigu pamagulu oponya.
Kodi chimalekanitsa chiyani fakitale yachitsulo chosapanga dzimbiri yopangira mchenga ndi ogulitsa? Choyamba: kuphatikiza koyima kupitirira kuponyera kokha. Mufunika okondedwa amene makina gawo lomwelo *pambuyo* kuponyera-chifukwa pokhapo pamene iwo amamva zotsalira za kupsinjika maganizo, carbide banding, kapena shrinkage wosafanana. Pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., CNC Machining siwowonjezera; ndi sitepe yomaliza yotsimikizira. Akamaliza chogudubuza cha T800 cobalt-based winch center shaft roller, amatsimikizira kuzungulira pamalo asanu axial-osati kutentha kwa chipinda, koma pambuyo poyeserera 120 ° C ntchito zilowerere. Umo ndi momwe mumagwirira kupotoza kusanafike pamzere wosonkhana.
Chachiwiri: kufufuza zinthu komwe kumapita mozama kuposa malipoti a mayeso a mphero. Makalasi achitsulo chosapanga dzimbiri monga AMS 5387 kapena ASTM A743 CA15 samachita zinthu mofanana pakuwotcha—ngakhale ndi kapangidwe kofananako. Kusiyanasiyana pang'ono kwa nayitrogeni kapena milingo ya delta ferrite kumasintha mphamvu, kuyankha kwa kutentha, komanso moyo wotopa. QINGDAO QIANGSENYUAN imasunga mgwirizano waukadaulo ndi ogulitsa zopangira zovomerezeka, kuwunikira kutentha kulikonse motsutsana ndi data yake yamkati ndi Charpy V-notch. Ngati kasitomala apempha 22% kuti achuluke pang'ono pakupanga kwa CF3M, samangovomereza satifiketi ya woperekayo-amatsimikizira pamakina awo oyesera, pogwiritsa ntchito zitsanzo zodulidwa kuchokera pamakina enieni otsanulira.
Chachitatu: kuwunika mosamalitsa komwe kumawonetsa kuuma kwa kugwiritsidwa ntchito komaliza. Zopeza zambiri zimayesa miyeso yovuta ndi ma CMM - koma ochepa amawona kukhulupirika kwapansi pa mchenga m'zigawo zosapanga dzimbiri. QINGDAO QIANGSENYUAN amagwiritsa ntchito magawo osiyanasiyana akupanga kuyezetsa (PAUT) pazigawo zonse zokhala ndi mphamvu zokhuthala kuposa mamilimita 25, kusanthula mizera yomwe imagwirizana ndi kukula kwa dendrite. Pazigawo zopanda kupanikizika monga maziko a pampu yamagalimoto a engineering, amapaka utoto wowunikira * atatha * kuchepetsa kupsinjika - komanso pambuyo popanga makina omaliza - kuti agwire ma microcracks otsegulidwanso. Lipoti lililonse limaphatikizapo mapu a malo, osati masitampu odutsa/alephera basi.
Chachinayi: luso lopanga kupanga-osati kutanthauzira kwa GD&T kokha, koma mayankho okhazikika ozikidwa pakupanga sayansi. Mwachitsanzo: pamene kasitomala adapereka chojambula chofuna ± 0.05 mm kulolerana pa nkhope ya flange ya 320 mm, gulu lawo silinatchule kapena kukana. Adapanga mawonekedwe olimba a shrinkage pogwiritsa ntchito MAGMAsoft, adazindikira madera omwe atha kukhala ankhondo, ndipo adaganiza zosamutsa zosindikiza ziwiri kuti zisamatenthetse kutentha. Chotsatira? Kuchepetsa kuchotsedwa kwa katundu wa post-machining ndi 40%, kuthetsa ntchito imodzi yomaliza popanda kusokoneza kusalala. Umenewo si ntchito - ndikugawana kuchepetsa chiopsezo cha uinjiniya.
Inde, kuponyera mchenga wa chitsulo chosapanga dzimbiri kumanyamula mtengo wokwera kuposa kuponya ndalama kwa maere ang'onoang'ono - kapena kuponyedwa pazigawo zopanda chitsulo. Koma popanga zida zapakatikati monga ma hydraulic pressure valves (50-500 pcs/chaka), ma silinda okhala ndi ngalande zoziziritsa mkati, kapena ma pampu am'mphepete mwa nyanja, kuponyera mchenga kumapereka kusinthasintha kosayerekezeka mu kukula, kusankha kwa aloyi, ndi makulidwe a khoma. Ndipo pamene gawo lanu liyenera kupulumuka m'madzi a m'nyanja odzaza ndi kloridi, kutsitsa kwapang'onopang'ono, ndi zofunikira zodutsira ziro, kudalirika sikutsika mtengo pa kilogalamu - kumagulidwa pa kulephera kopewedwa.
Ngati mukuyesa a zitsulo zosapanga dzimbiri zoponya mchenga fakitale, funsani mafunso atatu musanasaine NDA: Kodi angakuwonetseni lipoti laposachedwa la PAUT pakupanga kwa CF8M kofanana ndi geometry yanu? Kodi amasunga deta yosungunuka - kuphatikiza kutentha kwa madzi, kusanthula ladle, ndi kutentha kwa nkhungu - pa batch iliyonse yotumizidwa? Ndipo kodi iwo anakanapo kuponya kwawo chifukwa chakuti pambuyo-machining adavumbulutsa kuuma kosayembekezereka? Yankho kwa onse atatu amakuuzani zambiri kuposa ISO satifiketi iliyonse.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito kuchokera ku Qingdao-osati ngati kampani yotsatsa malonda akuponya kunja, koma monga wopanga ukadaulo komwe akatswiri azitsulo amawunikiranso zipika za ng'anjo pamodzi ndi opanga mapulogalamu a CNC. Cholinga chawo chimakhalabe chochepa: zigawo zamafakitale zomwe zimagwira ntchito zimatengera mawonekedwe, ndipo pomwe "zabwino" zimatanthawuza kulephera kwamunda. Chilango chimenecho ndichifukwa chake zitsulo zawo zosapanga dzimbiri zopangira mchenga zimapita ku ma OEM a hydraulic ku Germany, ophatikiza zida zapansi pamadzi ku Singapore, ndi omanga magalimoto amigodi ku Canada - osati chifukwa ndi otsika mtengo kwambiri, koma chifukwa ndi omaliza opanga mainjiniya oyimba pomwe choyimira choyamba chikulephera kuyesa kugwedezeka.
