Izindlu zempompo yokugalela yentsimbi eyenziwe ngokwezifiso ngeinkqubo yokuphosa isantikwayeCNC Machining.
I-Ductile cast iron, emele iqela lentsimbi, ekwabizwa ngokuba yi-nodular iron, spheroidal graphite cast iron or SG iron. I-nodular cast iron ifumana i-graphite ye-nodular ngokusebenzisa i-spheroidization kunye nonyango lwe-inoculation, oluphucula ngokufanelekileyo iimpawu ze-mechanical of iron cast, ngokukodwa i-plastiki kunye nokuqina, ukuze ufumane amandla aphezulu kune-carbon steel.
I-Ductile iron ayiyona nto enye kodwa iyinxalenye yeqela lezinto ezinokuveliswa ukuba zibe noluhlu olubanzi lweepropati ngokulawulwa kwe-microstructure. Uphawu oluqhelekileyo lweli qela lezinto eziphathekayo yimilo yegraphite. Kwiintsimbi ze-ductile, i-graphite ikwimo ye-nodules kunokuba i-flakes njengoko i-iron engwevu. Imilo ebukhali yeeflakes zegraphite zenza amanqaku oxinzelelo ngaphakathi kwe-matrix yesinyithi kunye nokumila okungqukuva kwamaqhuqhuva angaphantsi kangako, ngaloo ndlela kuthintela ukudalwa kweentanda kunye nokubonelela nge-ductility eyandisiweyo enika i-alloy igama layo.
I-Nodular cast iron iye yaphuhliswa ngokukhawuleza ibe yintsimbi yentsimbi yesibini kuphela kwintsimbi engwevu kwaye isetyenziswa ngokubanzi. Into ebizwa ngokuthi "intsimbi yokutshintsha intsimbi" ibhekisela kwintsimbi ye-ductile. Intsimbi erhuqwayo isoloko isetyenziselwa ukuvelisa iinxalenye zeecrankshafts kunye neecamshaft zeemoto, iitrektara, kunye neenjini zokutsha zangaphakathi, kunye neevalvu zoxinzelelo oluphakathi koomatshini ngokubanzi.
Kwinqanaba loyilo lweemveliso ze-iron ductile casting, iqela leprojekthi ekhethekileyo kufuneka limiselwe ukuba liqhube "iMode yokuFailela koYilo kunye noHlalutyo lweeMfumo" (DFMEA). Iqela leprojekthi ngokubanzi libandakanya abayili bemveliso, abayili benkqubo yokuphosa, kunye neengcali zokhuseleko lokusingqongileyo. Umxholo ophambili wohlalutyo lwe-DFMEA kufuneka ubandakanye ukuba iimfuno zomgangatho wokuphosa wesakhiwo senxalenye, inkqubo yokuphosa yesakhiwo sokuphosa, kunye nenkqubo yokuphosa kwiimfuno zokukhusela okusingqongileyo zonke zifezekisiwe.

Iimpawu zokuSebenza zeDuctile Iron Castings:
• Ulwelo kunye nokushwabana komgca we-iron ductile kusondele kakhulu kwezo zentsimbi engwevu
• Ukuthambekela kokunciphisa umthamo kunye nokwenziwa koxinzelelo lwangaphakathi kukhulu kunokwentsimbi yentsimbi engwevu, ethanda ukushwabana kunye nokuqhekeka.
• Amandla, iplastiki, kunye nelastiki imodyuli yentsimbi yentsimbi inkulu kuneyentsimbi engwevu, ikwazi ukumelana nokudubuka.
• Ukufunxa ngokothuka kubi kunentsimbi engwevu
Iimpawu zoLwakhiwo lwe-Ductile Iron Castings:
• Iyilwe ngokubanzi ukuba ilingane eludongeni ubukhulu, kwaye zama icandelo elishinyeneyo kufuneka lithintelwe ukuba kuyenzeka
• Kwiindawo ezithile ezityebileyo nezinkulu, ulwakhiwo olunomgongxo okanye ulwakhiwo oluneembambo eziqinisiweyo kufuneka zamkelwe
