Njira Yogwirira Ntchito ndi Mafotokozedwe Aukadaulo amakina opangira mchenga
Kukonzekera Nkhungu
Zinyalala za aluminiyamu zapamwamba kapena zopukutira zitsulo zimapangidwa mwaluso pogwiritsa ntchito makina a CNC a 5-axis, zomwe zimapangitsa kuti pamwamba pakhale roughness pansi pa Ra 1.6μm. Kapangidwe ka mtundu wogawanika kamakhala ndi ma angles odulira (nthawi zambiri 1-3°) ndi machining allowances (0.5-2mm) kuti zithandize kugwetsa. Ntchito zamafakitale nthawi zambiri zimagwiritsa ntchito zinyalala zophimbidwa ndi zigawo zotsalira za zirconia kuti ziwonjezere moyo wa ntchito kupitirira ma cycle 50,000.
Kudzaza ndi Kuumba Mchenga
Mchenga wa silica wolumikizidwa ndi mankhwala (85-95% SiO₂) umasakanizidwa ndi dongo la bentonite la 3-5% ndi madzi a 2-3% kuti likhale lolimba bwino. Makina opangidwa ndi botolo lopanda mabotolo amagwiritsa ntchito mphamvu ya 0.7-1.2 MPa, zomwe zimapangitsa kuti nkhungu ikhale yolimba kufika pa 85-95 pa B-scale. Pa ma engine block castings, sodium silicate-CO₂ hardness cores okhala ndi njira zotulutsira mpweya amayikidwa nkhungu isanatseke.
Kusonkhanitsa ndi Kukonza Nkhungu
Makina owonera a robotic amalumikiza magawo a nkhungu mkati mwa ±0.2mm kulekerera, pomwe mapini olumikizirana amasunga kulembetsa kwa makina otsekera. Ma C-clamp olemera amakhala ndi mphamvu yotsekera ya 15-20kN, yowonjezera ndi zolemera za nkhungu zazikulu (>500kg). Makampani opangira zinthu zoyambira amagwiritsa ntchito kwambiri kutsekera kwa electromagnetic popanga zinthu zambiri.
Kuthira
Zitsulo zoyendetsedwa ndi kompyuta zothira madzi zimasunga kutentha kwachitsulo pa 50-80°C kuposa kutentha kwa madzi. Makina apamwamba ali ndi masensa a laser ndi zipata zoyendera madzi zoyendetsedwa ndi PID, zomwe zimapangitsa kuti liwiro la kuthira likhazikike mkati mwa ±2%. Pa aluminiyamu (A356-T6), liwiro la kuthira limafika pa 1-3 kg/sekondi kuti achepetse kugwedezeka.
Kuziziritsa & Kulimbitsa
Nthawi yolimba imatsatira lamulo la Chvorinov (t = k·(V/A)²), pomwe ma k-values amasiyana kuyambira 0.5 min/cm² pazigawo zoonda mpaka 2.5 min/cm² pazigawo zolemera. Kuyika kwapadera kwa exothermic risers (15-20% ya voliyumu ya casting) kumathandizira kuchepa kwa madera ofunikira.
Kusakaniza ndi Kuyeretsa
Ma conveyor ogwedezeka okhala ndi mphamvu ya 5-10G amasiyanitsa 90% ya mchenga kuti ugwiritsidwenso ntchito kutentha. Kuyeretsa kwa magawo ambiri kumaphatikizapo ma tumbler ozungulira kuti achotsedwe koyamba, kutsatiridwa ndi kuphulika kwa robotic abrasive pogwiritsa ntchito chitsulo cha 0.3-0.6mm pa 60-80 psi.
Kuyang'anira & Kukonza Pambuyo
Makina oyezera ogwirizana (CMM) amatsimikiza miyeso yofunika kwambiri motsatira miyezo ya ISO 8062 CT8-10. X-ray tomography imazindikira zolakwika zamkati mpaka 0.5mm resolution. Chithandizo cha kutentha cha T6 cha aluminiyamu chimaphatikizapo kuyeretsa pa 540°C±5°C kutsatiridwa ndi kukalamba kochita kupanga.
Ubwino Waukulu:
Kusinthasintha kwa jiometri komwe kumathandiza kuti nyumba zikhale zopanda kanthu (monga, ma impeller a pampu okhala ndi makulidwe a khoma a 0.5mm)
Kusinthasintha kwa zinthu zomwe zimagwiritsidwa ntchito popanga zitsulo za ferrous/non-ferrous (HT250 imvi yachitsulo kupita ku AZ91D magnesium)
40-60% yotsika mtengo yopangira zida poyerekeza ndi 40-60% yopangira zida zoyezera zinthu zakale
Zolepheretsa ndi Zolepheretsa:
Mphamvu ya ogwira ntchito yachepetsedwa kudzera mu makina ogwiritsira ntchito mchenga okha
Kutaya nkhungu kumathetsedwa ndi 85-90% ya kuchuluka kwa mchenga wobwezeretsedwa
Zolepheretsa kumaliza pamwamba (Ra 12.5-25μm) zimagonjetsedwa ndi makina olondola
Quanzhou Juneng Machinery Co.,Ltd. ndi kampani yothandizidwa ndi Shengda Machinery Co.,Ltd. yomwe imadziwika bwino ndi zida zoponyera zinthu. Kampani yapamwamba kwambiri yofufuza ndi kukonza zinthu yomwe yakhala ikugwira ntchito yopanga ndi kupanga zida zoponyera zinthu, makina oumba okha, ndi mizere yopangira zinthu.
Ngati mukufunamakina opangira mchenga, mutha kulumikizana nafe kudzera muzidziwitso zotsatirazi:
