Uphando ngeNkqubo yokuVeliswa kweeMoto zeShell Castings

Ukusetyenziswa kwe-motor shell castings kuxhaphake kakhulu, kwaye ubunzima bokuveliswa kwayo kuxhomekeke kwisakhiwo, ubungakanani kunye neemfuno zobugcisa. Eli qokobhe lemoto lisetyenziswa kwiilocomotives zombane, kwaye iimfuno zomgangatho womphezulu kunye nomgangatho wangaphakathi wokusa uphezulu. Intsimbi etyhidiweyo esetyenziselwa ukugalela iqokobhe lemoto yi- ukuchithwa kwesithando somlilo.

Uhlalutyo lwenkqubo ye-motor shell castings

I-cavity yangaphakathi yendawo engaphezulu ye-casting iyinkimbinkimbi ngakumbi, kunye neeprotrusions zendawo; kukwakho ngakumbi iitsinki zobushushu ngaphandle kokugalela; ngoko ke, kukho ngaphezulu “T” kunye “L” node ubushushu ekugaleleni, kwaye kunzima ukondla ukuphosa. I-Flat cast kunye ne-cast, umsebenzi wokulinganisa ulula, kodwa ukondla kwe-motor shell casting kunzima kakhulu, ngokukodwa kwinxalenye ephumayo yomqolo wangaphakathi ongaphezulu kunye nesakhiwo esiyinkimbinkimbi, ngokusisiseko akukho ndlela yokusombulula ingxaki yokutya.

Ukugalela okuthe tyaba okanye okuthe nkqo, ukunyuselwa kubekwe kwindawo ephezulu, kodwa udonga lokugalela lungqindilili, olusezantsi lungqindilili kwaye oluphezulu lubhityile, kwaye ukugalela kumde, ukondla indawo esezantsi nako kunzima kakhulu. Ukongeza, i-deformation of castings nayo yingxaki ekufuneka ijongane nayo.

Uhlalutyo kunye nolawulo lokuguqulwa kwegobolondo le-motor casting

I-motor shell casting ayiyona i-cylinder epheleleyo. Kukho ezininzi izakhiwo ezincedisayo ezifana neentambo eziphakanyisiweyo kwi-cylinder. Ubunzima bodonga lwenxalenye nganye yokubunjwa buyahluka kakhulu, kwaye uxinzelelo ngexesha lokupholisa kunye nokuqina kwe-casting kuya kuba lukhulu. I-deformation ye-deformation ye-casting ayikwazi ukuqikelela ngokuchanekileyo. Ukuchithwa kokuqala kwegobolondo yemoto kunomahluko we-15 mm ububanzi bokuphela kombhobho othe tye, ongaphezulu kwe-elliptical. Ngokumisela intambo yokuphosa emise okweringi ekupheleni kombhobho othe tye, impazamo yobubanzi bokuphela kombhobho othe tye ingaphakathi kwe-1mm.
