Kusankha choyenera zitsulo zachitsulo ndondomeko si yosankha dzina pamndandanda. Ndi za kufananiza fiziki, geometry, ndi ntchito - nkhungu yoyamba isanatsanulidwe. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera magawo apadera a 12,000 a mavavu a hayidiroliki, nyumba zamapampu, ndi ma shafts akunyanja. Kulephera kulikonse kunatiphunzitsa chinachake konkire: kuponya mchenga sikungagwire ± 0.05 mm pampando wamphuno wa cobalt-alloy; ndalama kuponyera ming'alu ngati inu kulumpha preheat pa AMS 5387; ndi centrifugal kuponyera kumalephera momvetsa chisoni pamene makulidwe a khoma amatsika pansi pa 18 mm pazitsulo zothamanga kwambiri za silinda.
Yambani ndi gawo-osati ndondomeko
Mainjiniya ambiri amayamba ndikufunsa kuti "Ndi njira iti yopangira zitsulo yomwe ili yabwino?" Funso limeneli limatsogolera ku kuchulukirachulukira kapena kusachita bwino. M’malo mwake, funsani zinthu zitatu: Kodi idzanyamula katundu wotani? Zimalephera pati mu utumiki? Ndi kulolerana kotani komwe kumayenera kupulumuka pakamaliza kukonza?
Nthawi ina tidalandira chojambula cha nyumba yapampu ya T800 cobalt alloy piston — cholinga cha 350 bar. Wogulayo adatchulapo mchenga. Koma titatha kutengera kupsinjika kwamafuta ndi kuwunika kwa microstructure, tidalimbikitsa kuyika ndalama mokhazikika. Chifukwa chiyani? Kuponyera mchenga kunapanga kapangidwe kambewu kosagwirizana pafupi ndi mawonekedwe a valavu. Magawo awiri oyeserera adasweka pa bar 280 pakuyesa kophulika. Kuponyera ndalama kunabweretsa mipata yofanana ya dendrite, kudutsa mipiringidzo 420, ndikuchepetsa zotsalira za post-machining kuchokera 37% mpaka 9%.
Chotengera: Geometry imayendetsa njira kusankha. Mipanda yopyapyala, yovuta yokhala ndi kuyimba kolimba kwa GD&T kuti ipangitse ndalama. Maziko a zigawo zolemera? Kuponyera mchenga kumapereka kuwongolera bwino kwa mtengo komanso kukhazikika kwamafuta. Ma symmetry ozungulira ndi makulidwe a khoma lofanana? Kuponyedwa kwapakati kumapereka moyo wochuluka komanso wotopa kwambiri, makamaka pazigawo zapampu zachitsulo zosapanga dzimbiri zomwe zimakhudzidwa ndi kukokoloka kwa madzi amchere.
Zinthu zimatanthauzira denga lanu-ndi malire anu
Simungathe kuponya zomwe simungathe kuzidyetsa. Cobalt-nickel alloys monga AMS 5387 ndi T800 ali ndi malo osungunuka kwambiri (1370-1420 ° C), kutsika kwamadzimadzi, komanso kukhudzidwa kwambiri ndi kutentha kwa nkhungu. Tawonapo masitolo akuyesera kuwakakamiza kuti alowe mumchenga wobiriwira-kungotenga zitseko zozizira, kuchepetsa porosity, ndi interdendritic cracks. Izi si "zolephereka m'njira." Iwo ndi zinthu zosagwirizana ndi ndondomeko.
Malo athu ali ndi mizere iwiri yofananira: imodzi yokongoletsedwa ndi chitsulo ndi chitsulo cha kaboni (kuponyera mchenga, mpaka 500 kg), ina yoperekedwa ku ma superalloy apamwamba kwambiri (kuponyera ndalama, kutsanulira kothandizira, zipolopolo za ceramic preheated). Pa ma nozzles a AMS 5387, timagwiritsa ntchito zipolopolo zokhala ndi silika zomwe zimatenthedwa mpaka 1050 ° C - osati 800 ° C - kupewa kutenthedwa ndi kutentha ndikuwonetsetsa kuti nkhungu yadzaza. Kusintha kwa parameter kumodzi kumeneku kunadula ma oxide amkati ndi 63% pakuwunika kwathu kwa miyezi 18 yapitayi.
Musaganize kuti "chitsulo chosapanga dzimbiri" chimatanthauza chinthu chimodzi. 316 imakhala yosiyana kwambiri ndi 17-4PH kapena F22. Ndipo ma aloyi a cobalt amafuna njira zosiyanasiyana zolowera, kukwera, ndi kuziziritsa kuposa ma Inconels opangidwa ndi nickel. Ngati wogulitsa sakufunsani pepala lanu lonse lazitsulo-kuphatikiza mbiri yamankhwala otenthetsera komanso zomwe zimafunikira kukhazikika / kukhudzidwa - mwatsala kale.
Kuphatikiza kumapambana kudzipatula - nthawi iliyonse
Kuponyera kwangwiro sikungagwire ntchito ngati sikungathe kusindikizidwa. Timawona izi tsiku ndi tsiku: kasitomala amayitanitsa maziko achitsulo choponyedwa mchenga, kenako amafuna ± 0.025 mm kutsika pamtunda wa 600 × 400 mm. Zosatheka popanda kupsinjika maganizo ndi kukonza molondola. Kapena pulagi ya cobalt yoyika ndalama imafika ndi 0.3 mm kung'anima pamzere wotsatsira - kenako imakanidwa chifukwa shopu ya CNC ilibe zida zoboola kwambiri za ulusi wamkati wa 3.2 mm.
Ichi ndichifukwa chake QINGDAO QIANGSENYUAN TECHNOLOGY imaphatikiza kuponyera, chithandizo cha kutentha, machining amitundu yambiri, ndi kuyendera kwa CMM pansi pa denga limodzi logwirizana ndi ISO. Tikamatchula mawu a valve yokakamiza, timafanizira kayendedwe ka ntchito yonse: kubweza chipukuta misozi, nthawi yochepetsera kupsinjika, kapangidwe kake kakutchingira khoma, ndi kuyeza kwamaso kwa malo ovuta osindikizira. Sitimapereka magawo - timagawira zigawo zotsimikiziridwa.
Kuphatikiza uku kumachepetsa nthawi yotsogolera ndi 31% pamadongosolo apakati-voliyumu ndikuchotsa 94% ya kukonzanso mawonekedwe. Chofunika koposa, chimatilola kuthetsa mavuto asanakhalepo-monga kusintha khomo kuti muchepetse kupsinjika kotsalira mu chogudubuza cha winch center shaft roller kuti kugaya komaliza kukwaniritse Ra 0.4 µm popanda macheza.
Funsani mafunso oyenera - musanapereke
Musanasankhe a zitsulo zachitsulo mnzanu, tsimikizirani mfundo zisanu izi:
- Kodi amatsimikizira njira yawo yopangira - osati kungoyang'ana zotsatira zake? Funsani malipoti ofananitsa okhazikika ndi zipika zamafuta otsika pagawo lililonse.
- Kodi atha kutsata batch iliyonse ku ma cert opangira - kuphatikiza malipoti oyesa mphero ndi kusanthula kwazithunzi? Palibe kuchotserapo cobalt kapena faifi tambala aloyi.
- Kodi amayesa macheke a CMM pazobiriwira kapena sera - osati magawo omaliza? Zofunikira pamisonkhano ya GD&T-heavy ngati nyumba za silinda.
- Kodi chiwongolero chawo chotsimikizirika ndi chiyani pa aloyi yanu yeniyeni ndi geometry? Osati "avareji yamakampani" - anu.
- Kodi amawunikiranso kupangidwa kwaukadaulo pakutulutsidwa kwa uinjiniya-osati zida zitayamba? Timayika pachiwopsezo ngati njira zotsekera zomwe zimatchera zipolopolo za ceramic kapena radiyo yaying'ono kwambiri kuti igwirizane ndi mapini apakatikati.
Palibe njira yapadziko lonse "yabwino" yopanga zitsulo. Pali mafananidwe oyenera okha—pachikwama chanu chonyamula katundu, zinthu zanu, kulolerana kwanu, ndi zenera lanu loperekera zinthu zenizeni padziko lapansi. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Timachita chilichonse ngati kachitidwe - osati gawo. Chifukwa m'makina a hydraulic, zida zamafuta & gasi, ndi ma drivetrains a injiniya, gulu limodzi la porosity si cholakwika chodzikongoletsera. Ndi njira yotuluka. Chiyambi cha kutopa. Kulephera kwamunda kuyembekezera kuchitika.
Sankhani njira yomwe imalemekeza cholinga cha gawo lanu-osati mawonekedwe ake okha.
