Uyini Sand-Camera Iron Isikhunta Ekubunjweni

I-Iron mold sand-camera casting yinqubo yokusakaza lapho ungqimba oluncane lwesihlabathi lumbozwa emgodini wangaphakathi wesikhunta sensimbi (obizwa ngokuthi isikhunta sensimbi) ukwakha isikhunta. Ngoba ungqimba lokumboza isihlabathi lucishe lube mncane (4 ～ 8mm), kuyaqondakala ngokwezomnotho ukusebenzisa izinto ezibizayo ezisezingeni eliphakeme zokumodela. Ngenxa yalokhu, ikhwalithi yabalingisi ithuthuka kakhulu futhi imfucuza yehliswa kakhulu; ngenxa yobulukhuni besikhunta sensimbi esiboshwe ngesihlabathi esihle kakhulu, ngaleyo ndlela sithuthukisa ngokunemba okwenziwe ngamehlo nokuqina kokuphonsa.

IJalimane, izwe elaliyiSoviet Union namanye amazwe aqala ukusebenzisa okokufaka okusansimbi okusansimbi ekwenziweni kokulingisa ngawo-1960, ikakhulukazi ekukhiqizeni ama-ductile iron crankshafts, ama-brake hubs, ama-disc disc, ama-cylinder liners, amagobolondo amabhomu, amathrekhi amathangi nezisekelo zezimoto , njll. Uhlobo lokusakaza. Ucwaningo lwesicelo saseChina ku-iron mold sand-camera casting luqale ekuqaleni kwawo-1970. Ngo-1979, iZhejiang Mechanical and Electrical Design Institute kanye neYongkang Tractor Factory babambisene ukusebenzisa le nqubo okokuqala ekukhiqizeni ngobuningi izikhala ezingenalutho ze-S195. Ngasikhathi sinye, ukuhlolwa kokusebenza kwe-ductile iron crankshaft okhiqizwe yile nqubo kuqediwe, ngokuya ngamandla okukhathala (ukuqhathanisa ukucindezela komkhawulo wokukhathala σ-1), amandla okwephuka (ukuqhathanisa inani lomngcele ΔKth nokuqhathanisa ukuqina kobunzima K1C ) nempilo yesevisi (Ukuqhathanisa ukuhlolwa kokukhuthazela kwebhentshi elingu-10000h), njll., Uma kuqhathaniswa nesihlabathi sokuphonsa i-crankshaft, kungcono kunokusakazwa kwesihlabathi. Eminyakeni eyishumi elandelayo, inqubo iye yathuthukiswa ngokuqhubekayo ekusetshenzisweni. Ngasekuqaleni kweminyaka yama-10, izinkampani eziyisikhombisa zase zifake le nqubo, ikakhulukazi inqubo yokuphonsa insimbi enziwe ngesihlabathi yama-crinderhafts ayisilinda owodwa nama-cylinder crankshafts amane. Impumelelo enkulu.
