Copper bushing centrifugal casting

Itekhnoloji yokuphosa i-centrifugal ye-copper bushings yindlela esebenzayo kunye nechanekileyo yokuphosa, esetyenziswa ngokubanzi ekwenzeni i-alloy bushings yobhedu esetyenziselwa izixhobo zomatshini, iimoto, imigodi kunye nabanye oomatshini abanzima. Umgaqo-siseko we-centrifugal casting kukusebenzisa amandla e-centrifugal eveliswa ngumngundo ojikelezayo wesantya esiphezulu ukusabalalisa ngokulinganayo ulwelo lwentsimbi kudonga lwangaphakathi lomngundo, ngaloo ndlela lwenza ukuxinana okuphezulu kunye nokusebenza kakuhle.

Umgaqo osisiseko we-centrifugal casting technology

Ukugalelwa kwe-Centrifugal kukugalela ulwelo lwesinyithi olunyibilikisiweyo kwisingundo esijikelezayo, ukutyhala ulwelo lwesinyithi eludongeni lokungunda ngamandla aphakathi, kwaye ekugqibeleni yenze ukuphosa okuqinileyo. Ngethuba lenkqubo yokuphosa, ngenxa yesenzo samandla e-centrifugal, ubuninzi bemigangatho yangaphakathi nangaphandle yokuphosa iyahluka. Umaleko wangaphandle usondele eludongeni lokubumba, oludla ngokubumba ulwakhiwo oludityanisiweyo kunye noluxineneyo, kwaye umaleko wangaphakathi ukhululekile, olungele ukwenza ii-castings ezineempawu ezikhethekileyo zomzimba.

Inkqubo yokuphosa i-Centrifugal yeebhutsi zobhedu

I-copper bushings yenziwe ngokubanzi ngezinto ezixutywe nobhedu. Inkqubo ye-centrifugal casting ibandakanya la manyathelo alandelayo:

1. Ukulungiswa kwesikhunta Isikhunta ngokuqhelekileyo senziwe ngezinto ezinqabileyo eziphezulu, ezinokumelana nokushisa okuphezulu kwaye zihlale zizinzile ngexesha lokujikeleza. Udonga lwangaphakathi lwesikhunta lunokuthi luyilwe ngendlela ye-bushing.

2. Ukunyibilika kwesinyithi I-alloy yobhedu ifudunyezwa kwisimo esinyibilikisiweyo, ngokuqhelekileyo kwisithando somlilo esiphezulu, kwaye iqondo lokushisa elinyibilikayo liphakathi kwe-1050 ° C kunye ne-1150 ° C.

3. Galela isinyithi esinyibilikisiweyo Isinyithi esityhidiweyo sigalelwa kumngundo ojikelezayo kwidama elinyibilikisiweyo. Isantya sokujikeleza kwesikhunta sivame ukulawulwa ngamashumi ukuya kumakhulu eenguqu ngomzuzu, kwaye isantya sokujikeleza sichaphazela ngokuthe ngqo umgangatho kunye nesakhiwo sokuphosa.

4. Ukupholisa kunye nokuqina Isinyithi esityhidiweyo siqina kwi-mold ngenxa yokupholisa. Ngenxa yesenzo samandla e-centrifugal, isinyithi esityhidiweyo sisasazwa ngokulinganayo, senza udonga lwangaphandle oluphezulu, ngelixa udonga lwangaphakathi lukhululekile.

5. Ukuchithwa kunye nokuhlolwa Emva kokuba i-casting ipholile, isikhunta siyeka ukujikeleza, ukuchithwa kunye nokuhlolwa okufunekayo kuqhutywe ukuqinisekisa ukuba i-copper bushing ihlangabezana nobukhulu kunye neemfuno zomgangatho.

Izinto eziluncedo zokuphosa i-centrifugal bushings zethusi

Uxinaniso oluphezulu kunye namandla aphezulu: I-Centrifugal casting inokwenza umaleko wangaphandle we-casting dense ngokusebenzisa amandla e-centrifugal, kwaye ineempawu eziphezulu zoomatshini.

1. Iziphene zokuphosa ezimbalwa: Ukuphosa kwi-Centrifugal kunciphisa ukuveliswa kweziphene ezifana ne-pores kunye ne-inclusions, kwaye kuphucula umgangatho wokuphosa.

2. Ukumelana nokunxiba kakuhle: I-copper alloy bushings idla ngokusetyenziselwa ukumelana nokukhuhlana okukhulu. Itekhnoloji yokuphosa ye-Centrifugal yenza ubulukhuni bomphezulu be-castings buphezulu kwaye ukuxhathisa ukunxiba kungcono.

3. Ukuchaneka okuphezulu kokubumba: I-centrifugally cast copper bushings inokulawula ngokuchanekileyo ubungakanani kunye nokuma, ukunciphisa umsebenzi we-post-processing.

Izinto ezisebenzayo

Iimathiriyeli ze-alloy yobhedu ezidla ngokusetyenziswa ukwenza i-centrifugal casting ziquka:

Cast ubhedu (ofana ne-copper-tin alloy, ialloy yelothe yobhedu)

Ubhedu olutyhidiweyo (olufana nobhedu, i-aluminiyam yobhedu)

I-Aluminiyamu yobhedu, ezi ngxube zinokumelana nokugqwala okulungileyo kunye nokunganyangeki, zilungele ukusetyenziswa njengezinto ze-bushing.

Iindawo zesicelo

Itekhnoloji yokuphosa i-centrifugal ye-copper bushings ihlala isetyenziselwa ukwenza i-bushings ephezulu yokusebenza, iibheringi, izilayidi kunye nezinye iindawo, kwaye isetyenziswa ngokubanzi ku:

Izixhobo zoomatshini: ezifana nokuthwala amahlahla kwizixhobo zokuhambisa ngoomatshini.

Umzi-mveliso weemoto: Iibhutsi ezisetyenziselwa iinjini zeemoto, iibhokisi zegiya kunye nezinye iindawo.

Izixhobo zemigodi: Isetyenziselwa iindawo ezifuna ukuxhathisa okuphezulu kumatshini wokumba.

Impembelelo yeeparamitha zenkqubo

Isantya sokujikeleza: Isantya sokujikeleza simisela ukufana kokusasazwa kolwelo lwesinyithi kunye nobuninzi bokuphosa. Iphezulu kakhulu okanye iphantsi kakhulu iya kuchaphazela umgangatho wokusaswa.

Ubushushu bolwelo lwesinyithi: Ubushushu obuphantsi kakhulu besinyithi bunokukhokelela kulwelo olulambathayo, ngelixa ubushushu obuphezulu kakhulu bunokubangela lula i-oxidation kunye nezinye iingxaki.

Isantya sokupholisa: Isantya sokupholisa sichaphazela i-microstructure yokuphosa. Ukukhawuleza okanye ukucotha kakhulu kuya kuchaphazela ukusebenza kwe-copper bushing.

Ngamafutshane, itekhnoloji yokuphosa i-centrifugal ye-copper bushing yinkqubo esebenzayo yokuvelisa. Inokuvelisa i-copper alloy bushings eneempawu ezibalaseleyo zoomatshini, ukuchaneka okuphezulu komgangatho kunye nomgangatho ogudileyo. Yindlela efanelekileyo yokuvelisa kwiindawo ezininzi zoomatshini ezisebenza kakhulu.
