Mainjiniya akamatchula magawo a ma hydraulic system, mapampu akumunda wamafuta, kapena mawitchi olemera kwambiri, "fakitale yopangira zitsulo yolondola" singosaka chabe - ndi chofunikira chosakambitsirana. Dimensional bata pansi pa 500-bar pressure. Microstructure umphumphu pambuyo kutentha njinga. Kumapeto kwa pamwamba komwe kumakana kukokoloka kwa abrasive slurry. Izi si kulolerana - ndi mikhalidwe yopulumuka. Ndipo amafuna zoposa zida zoponyeramo; amafunikira chilango chazitsulo, kupitiriza kwa ndondomeko, ndi kuyankha kwaumisiri pa sitepe iliyonse.
Chifukwa Chake Cobalt Alloys Amafunikira Zambiri Kuposa Mizere Yoyimba Yokhazikika
Tawona ma projekiti ambiri akuyimitsidwa pomwe wogulitsa agwiritsa ntchito AMS 5387 cobalt alloy ngati chitsulo chosapanga dzimbiri cha 316. Chotsatira? Ming'alu m'nyumba zapampu pambuyo pa maola 400 akugwira ntchito. Warped center shaft rollers pamawilo amagalimoto a engineering. Kuuma kwa ng'anjo sikungathe kuberekana m'magulumagulu-ngakhale ng'anjo yofanana. Chifukwa chiyani? Chifukwa cobalt-nickel superalloys sikuti amangokana kuvala-amakana kulosera. Mapiritsi awo amatenthetsa ndi theka la chitsulo. Kuchepa kwawo kolimba kumasokonekera. Kuthekera kwawo kumatsika ndi 70% pambuyo pa njira yothetsera.
Ichi ndichifukwa chake mafakitole opangira zitsulo zowona bwino amaikamo zinthu zotsekeka-osati manambala a batch okha, koma zipika za mbiri ya kutentha zomwe zimamangiriridwa pakuponya kulikonse. Amayenereza zomangira mchenga za T800-grade alloys, osati silika wamba. Amatsimikizira kuzungulira kwa zipolopolo zowononga ndalama ndi mapu a thermocouple-osati zongotengera nthawi. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mphuno ya cobalt iliyonse kapena pulagi imayamba ndi zinthu zovomerezeka kuchokera kwa ogulitsa Tier-1-ndipo imatha ndi lipoti la CMM lomwe likuwonetsa kupatuka kwa ± 0.015 mm pamalo osindikizira ovuta, kutsimikiziridwa makina asanayambe.
Kuphatikiza Koyima Si Buzzword-Ndi Njira Yokhayo Yogwirizira GD&T
Ogulitsa ena akuponya kunja, kenako amagula CNC pamisika yomwe ilipo. Izi zimapanga malo atatu olephereka: kusuntha kwapang'onopang'ono pakati pa madera opangidwa ndi makina, mawindo otenthetsera osakanikirana, ndi ziro kuwongolera kukhulupirika pamwamba musanamalize. Tawunikanso magawo ambiri okanidwa pomwe kuponyedwa kumakumana ndi zinthu zina, koma mawonekedwe a as-cast anali ndi micro-porosity yomwe idawonekera pambuyo popera komaliza.
Kuphatikizika koona kumatanthauza kulamulira unyolo wonse: kuponya ndalama → kuchepetsa nkhawa → makina amitundu yambiri → chithandizo cha kutentha kwapambuyo → kutsirizitsa mwatsatanetsatane pamwamba. Kwa nyumba za silinda za pampu ya pistoni, izi zikutanthauza kugwira mozungulira mkati mwa 0.008 mm kutalika kwa 300 mm - ngakhale mutatulutsa nitriding. Kwa mavavu oponderezedwa, kumatanthauza kusunga kukhazikika pakati pa bere la mpando ndi chotchingira chakunja mkati mwa 0.02 mm - kudutsa matupi onse achitsulo oponyedwa mchenga ndi zida zomangirira za cobalt. Izi sizingatheke popanda data yogawana zida, kulinganiza kolumikizidwa, ndi kusaina kwa gulu limodzi pakusintha kulikonse.
Kodi "Kulondola" Kutanthawuza Chiyani Kwenikweni Pakuponya Kwamafakitale (Kupitilira Ma Microns)
Funsani mainjiniya khumi kuti "kulolera kwakukulu" kumatanthauza chiyani, ndipo mupeza mayankho khumi ndi limodzi. Koma m'mapulogalamu enieni adziko lapansi, milu ya kulolerana simakhala payokha. Nyumba yofikira ±0.02 mm imakhala ndi vuto pokhapokha ngati kuuma kwa shaft yokwerera sikukhala pansi pa Ra 0.4 µm—ndipo ngati mphamvu yokulirapo ya zinthu zonse ziwirizo ilumikizana mkati mwa 10% kudutsa -20°C mpaka +120°C.
Ichi ndichifukwa chake mafakitale opangira zitsulo zolondola amayenera kuyika chitsimikiziro chogwira ntchito - osati kungoyang'ana mozama. Valavu iliyonse yokakamiza imayesedwa ndi hydrostatic pa 1.5 × kugwira ntchito. Winch center shaft roller iliyonse imatsimikizira kutsimikizika kwamphamvu pa 3,500 RPM. Nozzle iliyonse ya cobalt alloy imadutsa kuyang'ana kolowera mkati * ndi * ultrasonic scanning ya subsurface dendritic segregation. Izi si zowonjezera. Amapangidwa kukhala malangizo a ntchito-ndi njira zodutsa / zolephera zolembedwa, zowerengeka, ndikusungidwa kwa zaka 10.
- CNC makina makina: 5-olamulira contouring kwa zovuta otaya njira mkati
- Zigawo za Cobalt-nickel: AMS 5387 & T800 alloy processing ndi kutsata kutentha kwathunthu
- Kuponyedwa kwachitsulo: EN-GJS-400-15 chitsulo chotulutsa chitsulo chokhala ndi spheroidization mlingo> 95%
- Zitsulo & zosapanga dzimbiri: ASTM A351 CF8M ndi intergranular dzimbiri kuyezetsa pa ASTM A262 Practice E
Kusankha Mnzanu—Osati Wongopereka
Madeti otumiza. Zojambula zimasintha. Zida zimasinthidwa. Chomwe chimasiyanitsa fakitale yodalirika yopangira zitsulo ndi momwe zinthuzo zimachitikira, osati ngati zikuchitika. Tawona makasitomala akutaya miyezi pomwe wogulitsa anakana kutanthauzira kwa GD&T pakuwunikanso kapangidwe kake, akuumirira kuti "ingotumizani zojambulazo." Ena adachedwetsa ma prototypes ndi masabata asanu ndi limodzi chifukwa choyambira chinalibe mphamvu yotsimikizira makulidwe a khoma panjira yosindikizira ya 3D.
Wothandizana naye woyenera amayamba ndi mayankho akupanga-osati atatha kunena, koma pakuwunikanso uinjiniya. Amayimitsa ma angles omwe amachititsa kuti zipolopolo ziwonongeke muzitsulo za cobalt. Amapereka njira zina zochepetsera porosity pamapampu okhala ndi mipanda yopyapyala. Amatsimikizira ziphaso zofananira ndi malo omwe mumagwiritsa ntchito kumapeto—kaya ndi gasi wowawasa (NACE MR0175) kapena kukana dzimbiri panyanja (ISO 12944 C5-M).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito motere - osati monga ndondomeko, koma monga machitidwe a tsiku ndi tsiku. Malo ake ogwirizana ndi ISO amayang'anira chilichonse kuyambira pakupanga ma prototypes amodzi mpaka kupanga ma volume apakati, ndikukonzekera mwadongosolo komwe kumayang'anira zinthu zomwe sizikuyenda bwino munthawi yeniyeni. Palibe "ndalama zothamangira." Palibe zodabwitsa zolipiritsa za NRE. Njira zongolembedwa, zotsatira zotsatirika, ndi zokambirana zamainjiniya zomwe zimayamba ndi "Kodi gawoli lilephera bwanji?" -osati "Kodi mtengo wake ndi wotani?"
Ngati ntchito yanu yotsatira ikukhudza mavavu othamanga kwambiri, zomangira mapampu, kapena mashaft osatha, yambani ndi funso: Kodi fakitale yanu yowomba zitsulo yolondola kwambiri imayesa kupambana kwa ma microns—kapena pakapita nthawi pakati pa kulephera? Yankho limatsimikizira ngati gawo lanu limatenga maola 500 kapena 5,000.
