Yintoni ukuqina kwe-induction? Uthini umphumo wokwenziwa lukhuni kweentonga zepiston?

Xa ukunyibilika kwesinyithi kuqhutyelwa, ukucima kuyimfuneko. Nangona kunjalo, iintsimbi ezahlukeneyo zineendlela ezahlukeneyo zokucima. Ngoku uza kukubonisa ukuba yintoni ukuqina kwe-high-frequency, kwaye yintoni umphumo wokuqina okuphezulu kwee-piston rods?

Piston intonga induction ukuqina

Yintoni ukuqina kwe-induction

Ukucima i-high-frequency quenching ubukhulu becala isetyenziselwa ukucima umphezulu weendawo zesinyithi. Yindlela yonyango yokushisa yesinyithi eyenza i-induction current ethile kumphezulu we-workpiece, ishushu ngokukhawuleza umphezulu wenxalenye, kwaye emva koko iyayicima ngokukhawuleza. Isixhobo sokufudumeza induction sibhekiselele kwisixhobo esenza ukufudumeza kwe-induction kwisixhobo sokusebenza sokuqina komphezulu. Ngokufudumeza ngokukhawuleza, umphezulu wentsimbi oza kucutshungulwa ufikelela kubushushu bokucima. Xa ubushushu budluliselwa kwiziko, bupholile ngokukhawuleza. Kuphela umphezulu uqiniswe kwi-martensite, kwaye iziko ayikacinywa. I-ductility yasekuqaleni kunye nokuqina annealing (okanye elungileyo Fire and tempering) umbutho.

Yintoni umphumo wokucinywa kwefrikhwensi ephezulu yentonga yepiston

Intonga yepiston yinxalenye yokudibanisa exhasa umsebenzi wepiston. Uninzi lwayo lusetyenziswa kwiisilinda zeoyile kunye neenxalenye zokubulawa kwe-cylinder. Yinxalenye ehambayo kunye nokuhamba rhoqo kunye neemfuno eziphezulu zobugcisa. Ngokutsho kwe-Youzho Energy Saving, emva kokucinywa kwe-high-frequency yentonga ye-piston, umphezulu wentonga ye-piston unokufumana isakhiwo se-martensitic ngaphakathi koluhlu oluthile lobunzulu, ngelixa inxalenye engundoqo isagcina imo yesakhiwo phambi kokucinywa komphezulu (inomsindo okanye isimo esiqhelekileyo) ) Ukuze ufumane umaleko oqinileyo nongagugiyo, kunye nokumila okwaneleyo kunye nokuqina kwentliziyo. Xa intonga yepiston iphantsi kokucinywa kwe-high-frequency quenching, ngokuqhelekileyo iphantsi kwe-intermediate-frequency okanye i-high-frequency quenching emva kokusila ngokurhabaxa, ukufudumeza kwe-induction ukuya kwi-1000-1020, kunye nokupholisa nge-0.05-0.6MPa yokuxininiswa kwenaliti yomoya, kunye nokuqina. ubunzulu bomaleko 1.5-2.5 mm , Ukulungisa unyango emva kokucima. Emva koko, ihlanjululwe kwi-200-220, ibambe ixesha le-1 ukuya kwiiyure ze-2, kunye ne-air-cooled kwiqondo lokushisa, kunye nobunzima obungaphezulu kwe-HRC50.

Intonga yepiston yinxalenye ebalulekileyo yomgangatho wokukhwela. Emva kokucima i-high-frequency quenching ye-piston rod, ukuqina kunye nokuqina kwendawo yayo kunokunyuswa, ngaloo ndlela yenza intonga ye-piston ingagugi.
