Mutengi Nyaya: Tractor Gearbox Housing Manufacture muPoland
Customer Background: Mutengi wepakati wezvekurima wemuchina muPoland, achishandira New Holland naJohn Deere, anofanirwa kugadzirisa grey cast iron (HT250) gearbox dzimba nezvinodiwa zvepagore zve50,000 zvidimbu.
Zvinetso Zvinonetsa: Ukobvu hwemadziro eimba hauna kuenzana (8-30mm), inoda kugadzirisa shrinkage mhango uye shrinkage porosity defects, uye hapana kuvuza mukuyedza kumanikidza mvura (1.5MPa, maminitsi makumi matatu); iyo flatness yemusangano wepamusoro ≤0.03mm, inoda kunyatsoenderana nechigaro chekutakura uye gearbox; mutengi anoda zvakatipoteredza kurapwa kwepamusoro panzvimbo pechinyakare electroplating, kutevedzera EU RoHS rairo.
Ruican Solution: 1. Casting Process: Yakarasika furo kukanda (EPS) → yepakati frequency choto kunyunguduka → kudira → kuchembera kurapwa → CNC milling → bvunzo yekumanikidza mvura. 2. Defect Control: Shandisa ProCAST simulation kuti uwedzere gating system, isa chills muzvikamu zvakakosha kuti uderedze njodzi ye shrinkage cavity. 3. Surface Treatment: Gamuchira zvakatipoteredza poda coating (RAL7037) panzvimbo ye electroplating, kupfuura RoHS test.
Quantitative Results: Muyero wakakodzera wekuedzwa kwemvura ndeye 99.9%, chiyero chekukanda chakaderedzwa kubva pa3% kusvika pasi pe0.5%; vhoriyamu yegore negore yakadzikama 50,000 zvimedu, chiyero chekusvika panguva ndeye 100%, uye mutengi wemazuva ekutengesa ekutengesa anoderedzwa nemazuva gumi nemashanu; mugore rechitatu rekubatana, mutengi akawedzera hurongwa hweimba yeclutch, uye kutengesa kwegore negore kwakawedzera ne40%.
Kudyidzana Kukosha: Iva mudiwa wenguva refu weEuropean michina yekurima yepakati neiyo chaiyo yekukanda uye kuchengetedza kwezvakatipoteredza tekinoroji, uye kuwedzera akawanda-mapoka ekutsigira.
