Yintoni umahluko phakathi ukucima rhoqo kunye nokucima okuphakathi?

Umgaqo osebenzayo wokucinywa kwe-high-frequency quenching kunye ne-intermediate-frequency quenching iyafana naleyo yokufudumeza kwe-induction: oko kukuthi, i-workpiece ibekwe kwi-inductor, kwaye i-inductor ngokuqhelekileyo iyityhubhu yobhedu engenanto ifaka i-frequency ephakathi okanye i-high frequency alternating current. (1000-300000Hz okanye ngaphezulu). Indawo yamagnethi etshintshanayo yenza umsinga ovunyiweyo wefrikhwensi efanayo kwindawo yokusebenza. Ukusasazwa kolu hlobo lwangoku olubangelwayo kwi-workpiece alulingani, lunamandla phezu komhlaba, kodwa lubuthathaka kakhulu ngaphakathi, kwaye lusondele kwi-0 phakathi. Esi siphumo sesikhumba sisetyenziswa. , umphezulu we-workpiece unokufudumeza ngokukhawuleza, ubushushu bomhlaba bukhuphukela kwi-800-1000 ℃ ngemizuzwana embalwa, kwaye ubushushu becala eliphambili lincinci kakhulu.

Nangona kunjalo, ngexesha lenkqubo yokufudumala, ukuhanjiswa kwe-current induced kwi-workpiece ayilingani, kwaye umphumo wokufudumala oveliswa ngamaza ahlukeneyo akhoyo nawo ahluke. Ke, umahluko phakathi kokucima i-high-frequency quenching kunye ne-intermediate-frequency quenching iza:

1. Ukucima rhoqo rhoqo

I-frequency yangoku phakathi kwe-100 kunye ne-500 kHz

Umaleko wokuqina ongekho nzulu (1.5 ~ 2mm)

Izinto eziluncedo emva kokucinywa kwamatyeli amaninzi: ubunzima obuphezulu, i-workpiece ayilulanga ukuba ifakwe kwi-oxidized, i-deformation incinci, umgangatho wokucima ulungile, kunye nokusebenza kakuhle kwemveliso kuphezulu.

Ukucima i-high-frequency quenching ifanelekile kwiindawo ezisebenza phantsi kweemeko zokukhuhlana, njengeegiya ezincinci kunye neeshafts (izinto ezisetyenziswayo ziyi-45 # intsimbi, i-40Cr)

2. Intermediate frequency quenching

I-frequency yangoku yi-500 ~ 10000 Hz

Umaleko oqinileyo unzulu (3~5mm)

Ukucinywa kwamaxesha aphakathi kufanelekile kumacandelo aphantsi kokujija kunye noxinzelelo lwemithwalo, njengee-crankshafts, iigiya ezinkulu, i-spindles yomshini wokusila, njl.

Ngamafutshane, enye yeeyantlukwano ezicacileyo phakathi kokucima i-high-frequency quenching kunye ne-intermediate-frequency quenching ngumahluko wokutshisa ukushisa. Ukucima i-high-frequency quenching inokuqinisa ubuso ngexesha elifutshane, isakhiwo se-crystal silungile kakhulu, kwaye i-deformation yesakhiwo incinci. Yiba mncinci.
