Pamene mainjiniya afotokoza zitsulo zoponyera ndalama za carbon steel, sikuti amangoyitanitsa zitsulo-amafuna kukhazikika kwapakati pa 350 bar hydraulic pressure, microstructural consistency kudutsa 500-unit batches, ndi kukhulupirika kwa pamwamba komwe kumapulumuka kutuluka kwa slurry kwa maola 12,000 ogwirira ntchito. Mlingo wa magwiridwe antchitowo suchokera kuzinthu zoyambira. Zimafunika a mpweya zitsulo ndalama kuponyera mbali fakitale kumangidwa mozungulira zitsulo - osati kungoponyera mphamvu.
Chifukwa chiyani Investment Casting Imapambana pa Carbon Steel Critical Components
Kuponyedwa kwa mchenga kumayang'anira kupanga zitsulo za carbon zitsulo-koma zimalephera pamene zovuta za geometry zimakumana ndi kuuma kwa ntchito. Tawonapo nyumba za silinda za pampu ya piston zikanidwa kawiri: choyamba chifukwa cha 0.18 mm makulidwe a khoma m'dera la valavu, kenako ndi micro-porosity pafupi ndi madera omwe amakhudzidwa ndi kutentha pambuyo pothetsa nkhawa. Kuponya ndalama kwathetsa zonse ziwiri. Dongosolo lake la zipolopolo la ceramic limapereka kulolerana kwa ± 0.05 mm pazomwe zili ngati ngalande zoziziritsa zamkati ndi ziboliboli zokhala ndi ma concentric - popanda ma ngodya kapena mizere yolekanitsa. Chofunikira kwambiri, kuwongolera kolimba kolowera kumachepetsa kung'ung'udza kwapang'onopang'ono mpaka kuonda komwe kumachitika m'matupi okakamiza a valve ndi ma winch center shaft rollers. Kusinthanitsa? Mtengo wokwera pagawo lililonse. Phindu lake? Zero rework pa GD&T-critical datums. Kwa mapulogalamu omwe kulephera kumatanthauza kutsika mtengo $18,000 / ola, masamuwa sangakambirane.
Umphumphu Wakuthupi Umayamba Usanathiridwe
Zopangira zitsulo za kaboni zimalephera—osati chifukwa cha luso lotayirira losauka—koma chifukwa cha zakudya zosagwirizana. Tidatsatirapo kusweka kobwerezabwereza mu ASTM A216 WCB maziko a mpope mpaka kugawanika kwa manganese m'magulu a billet otengedwa kuchokera ku mphero zitatu zosiyanasiyana. Masiku ano, kusungunuka kulikonse kumayamba ndi ma ingots ovomerezeka a 1020-1045, otsimikiziridwa kudzera pa OES spectroscopy asanalipire. Chofunika kwambiri, timatenthetsa kutentha ndi mipiringidzo yofananira - palibe zongoyerekeza "zoyimira". Izi zimatsimikizira kusintha kwa gawo lofanana pakati pa gawolo ndi lipoti lake lamakina. Pazigawo za AMS 5387 cobalt alloy (zomwe nthawi zambiri zimaphatikizidwa muzitsulo za kaboni), timasunga kusungunuka kwapawiri: gulu limodzi la botolo la cobalt, lina la nyumba yachitsulo cha kaboni - ndi zolemba zonse zolumikizana ndi chipika cha ng'anjo yotentha yofanana. Palibe njira zazifupi. Palibe kusakanikirana kwamagulu.
Kumene Kuponyera Kutha, Kulondola Kumayambira
Kujambula kwangwiro sikutha pa kugwedeza. Zimatha pamene 0.002 ″ pamwamba pampando wa valve wopanikizika udutsa kuyesa kwa helium pa 10.−9 mbar·L/s. Izo zimafuna kuphatikiza ofukula - osati kuponyera, koma CNC Machining, kutentha kutentha, ndi metrology pansi pa denga limodzi. Malo athu a ISO 9001 amayendetsa ma 5-axis milling pa post-annealed castings kuti akhale ndi malo enieni mkati mwa 0.01 mm pamapangidwe a 12-hole flange. Timasindikiza malo omaliza osindikizira * pambuyo * mpumulo wa kupsinjika, osati kale - kuchotsa njira zotayikira zoyambitsa nkhondo. Kuyendera kwa CMM si chipata chomaliza; imayikidwa mkati mwa ndondomeko. Pambuyo pa makina ovuta, timatsimikizira kukhazikika kwa bore. Pokhapokha timapitiriza kumaliza mabala. Izi zimapangitsa kuti kutentha kuyambike msanga-kupulumutsa maola 72 akuwononga nthawi yomaliza panyumba yayikulu.
Kutsimikizika Kwapadziko Lonse, Osati Kungotsatira Mapepala
Makasitomala amafunsa kuti: "Kodi mutha kunyamula mapulagi a T800 a cobalt aloyi wowotcherera muzitsulo za kaboni?" Inde, koma chifukwa chakuti tatsimikizira mgwirizano wazitsulo wosiyana-siyana kupyolera mu 500 matenthedwe matenthedwe (-40 ° C mpaka +250 ° C) ndi mapu a ultrasonic bond integrity. Iwo amafunsa kuti: “Kodi nyumba za silinda zanu zimapulumuka kukokoloka kwa mapampu a madzi a m’nyanja?” Inde, chifukwa timawayesa m'mizere yathu yozungulira yokhala ndi 12% silica zomwe zili pa 2800 RPM kwa maola 400, kuyeza kutayika kwa zinthu kudzera pa laser profilometry. Satifiketi ndiyofunikira, koma machitidwe akumunda amafunikira kwambiri. Ichi ndichifukwa chake kutumiza kulikonse kumaphatikizapo kutsatiridwa kwathunthu: nambala yosungunuka, ID yozungulira kutentha, seriyoni ya lipoti la CMM, ndi kusaina kwa oyendetsa-osati satifiketi yongotsatira.
Pazigawo zofunika kwambiri zopangira ndalama za kaboni zitsulo, kuthekera sikuyezedwa mu matani kapena masikweya mawonedwe. Imayesedwa mu ma microns a kulolerana komwe kumachitika, maola ogwirira ntchito, ndi zolephera zomwe zimalepheretsedwa ntchito isanayambe. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito ngati a mpweya zitsulo ndalama kuponyera mbali fakitale kumene zitsulo zimayendetsa makina—ndipo pamene kuponyedwa kulikonse kumanyamula kulemera kwake, osati pepala lake lokhalokha.
