Maitiro Ekushanda uye Magadzirirwo Ehunyanzvi emuchina wekuumba jecha
Kugadzirira Foroma
Zviumbwa zvealuminium alloy kana ductile iron zvemhando yepamusoro zvinogadzirwa nemazvo kuburikidza ne5-axis CNC systems, zvichiita kuti surface roughness ive pasi peRa 1.6μm. Dhizaini yemhando iyi inosanganisira ma draft angles (kazhinji 1-3°) uye machining allowances (0.5-2mm) kuti zvive nyore kubvisa. Mashandisirwo emaindasitiri anowanzo shandisa zviumbwa zvakaputirwa zvine zirconia-based refractory layers kuti zviwedzere hupenyu hwebasa kupfuura 50,000 cycles.
Kuzadza Jecha & Kuumba
Jecha resilica rakasungirirwa nemakemikari (85-95% SiO₂) rinosanganiswa nevhu re3-5% rebentonite uye 2-3% mvura kuti rive rakasimba. Michina yekuumba isina flask inoshandisa 0.7-1.2 MPa compaction pressure, zvichiita kuti kuoma kwemold kuve 85-95 paB-scale. Pakuumbwa kwe engine block, sodium silicate-CO₂ hardered cores dzine nzira dzekuburitsa mweya dzinoiswa mold isati yavharwa.
Kuungana & Kugadzirisa Mould
Masisitimu ekuona erobhoti anogadzirisa zvikamu zvechimurenga mukati me ±0.2mm kushivirira, ukuwo mapini ekuona anobatana achichengetedza kunyoreswa kwechimurenga chegating. MaC-clamps ane simba guru anoshandisa simba re 15-20kN clamping, achiwedzerwa nemabhuroko ehuremu hwechimurenga chikuru (>500kg). Makambani ekugadzira zvinhu anowedzera kushandisa electromagnetic locking kugadzira zvinhu zvakawanda.
Kudurura
Mafuroni anodzorwa nekombiyuta anochengetedza kupisa kwesimbi zvakanyanya pa50-80°C pamusoro pekupisa kwemvura. Masisitimu epamusoro ane masensa elaser-level uye mageti ekuyerera anodzorwa nePID, zvichiita kuti kudira kugadzikane mukati me ±2%. Kune alloys dzealuminium (A356-T6), kumhanya kwekudira kwakajairika kunosvika 1-3 kg/sec kuderedza turbulence.
Kutonhodza & Kusimbisa
Nguva yekusimba inotevera mutemo waChvorinov (t = k·(V/A)²), apo k-values inosiyana kubva pa0.5 min/cm² yezvikamu zvitete kusvika pa2.5 min/cm² yezvinogadzirwa zvinorema. Kuiswa kwe exothermic risers (15-20% yehuwandu hwekukanda) kunotsiva shrinkage munzvimbo dzakakosha.
Kushambadza & Kuchenesa
Ma conveyor anodzungudza ane simba re5-10G anoparadzanisa 90% yejecha kuti ridzorerwe pakupisa. Kuchenesa kwematanho akawanda kunosanganisira ma tumbler anotenderera kuti abvise maburi pakutanga, zvichiteverwa ne robotic abrasive blasting uchishandisa 0.3-0.6mm steel grit pa60-80 psi.
Kuongorora & Kugadziriswa Mushure meKugadzirwa
Michina yekuyera yakabatana (CMM) inoongorora zviyero zvakakosha zvinoenderana neISO 8062 CT8-10 standards. X-ray tomography inoona zvikanganiso zvemukati kusvika pakukwana kwe 0.5mm. Kurapa kupisa kweT6 kwearuminiyamu kunosanganisira kuisa solution pa 540°C±5°C zvichiteverwa nekukwegura kwekugadzira.
Zvakanakira Zvikuru:
Kuchinjika kwejiyometri kunogonesa zvivakwa zvisina chinhu (semuenzaniso, mapombi ekufambisa ane ukobvu hwemadziro hwe0.5mm)
Kushandiswa kwezvinhu zvakasiyana-siyana kunosanganisira ferrous/non-ferrous alloys (HT250 grey iron kusvika AZ91D magnesium)
Mari yekushandisa maturusi yakaderera ne40-60% uchienzaniswa nekushandisa mapuroteni ekugadzira maturusi emhando yepamusoro (die casting)
Zvipingamupinyi & Zvidzikiso:
Kusimba kwevashandi kunoderedzwa kuburikidza nehurongwa hwekugadzirisa jecha otomatiki
Kurasika kwevhu kunogadziriswa kuburikidza ne85-90% yehuwandu hwekudzoreredza jecha
Miganho yekupedzisa pamusoro (Ra 12.5-25μm) inokundwa nekugadzira nemazvo
Quanzhou Juneng Machinery Co.,Ltd. ikambani iri pasi peShengda Machinery Co.,Ltd. inonyanya kugadzira michina yekukanda. Bhizinesi reR&D repamusoro-soro rave richigadzira nekugadzira michina yekukanda, michina yekuumba otomatiki, uye mitsetse yekukanda.
Kana uchidamuchina wekuumba jecha, munogona kutibata kuburikidza neruzivo rwekuonana runotevera:
