Uyini umehluko phakathi ukucima imvamisa ephezulu kanye nokucisha imvamisa emaphakathi?

Umgomo wokusebenza wokucisha imvamisa ephezulu kanye nokucisha imvamisa yamaphakathi kuyafana nalokhu kokushisisa kokungeniswa: okungukuthi, ucezu lokusebenza lubekwe ku-inductor, futhi i-inductor ngokuvamile iyishubhu yethusi engenalutho efaka imvamisa yamaphakathi noma i-high frequency alternating current. (1000-300000Hz noma ngaphezulu). Inkambu kazibuthe eshintshanayo ikhiqiza amandla akhona wemvamisa efanayo kucezu lokusebenza. Ukusatshalaliswa kwalokhu kwamanje okwenziwe ku-workpiece akulingani, kunamandla ebusweni, kodwa kubuthakathaka kakhulu ngaphakathi, futhi kuseduze no-0 phakathi nendawo. Lo mphumela wesikhumba usetshenziswa. , ingaphezulu le-workpiece lingashiswa ngokushesha, izinga lokushisa elingaphezulu likhuphukela ku-800-1000 ℃ ngemizuzwana embalwa, futhi izinga lokushisa lengxenye eyinhloko lincane kakhulu.

Kodwa-ke, phakathi nenqubo yokushisa, ukusatshalaliswa kwamanje okwenziwe ku-workpiece akulingani, futhi umphumela wokushisa okhiqizwa ama-frequencies ahlukene wamanje nawo uhlukile. Bese, umehluko phakathi kokucisha imvamisa ephezulu kanye nokucisha imvamisa yamaphakathi uyeza:

1. High frequency quenching

Imvamisa yamanje iphakathi kuka-100 no-500 kHz

Isendlalelo esingaqinile (1.5 ~ 2mm)

Izinzuzo ngemuva kokucisha imvamisa ephezulu: ubulukhuni obuphezulu, i-workpiece akulula ukuthi ifakwe i-oxidized, i-deformation incane, ikhwalithi yokucisha ilungile, nokusebenza kahle kokukhiqiza kuphezulu.

Ukucisha imvamisa ephezulu kulungele izingxenye ezisebenza ngaphansi kwezimo zokungqubuzana, njengamagiya amancane namashafti (izinto ezisetshenziswayo ziyi-45# steel, 40Cr)

2. Ukucima imvamisa okuPhakathi

Imvamisa yamanje yi-500 ~ 10000 Hz

Isendlalelo esiqinile sijulile (3~5mm)

Ukucisha imvamisa okumaphakathi kufanelekile ezingxenyeni ezingaphansi kokusonteka nemithwalo yengcindezi, njengama-crankshafts, amagiya amakhulu, ama-spindle omshini wokugaya, njll. (izinto ezisetshenziswayo ziyi-45# steel, 40Cr, 9Mn2V kanye ne-ductile graphite.

Ngamafuphi, umehluko osobala phakathi kokucisha imvamisa ephezulu kanye nokucisha imvamisa emaphakathi umehluko wokujiya kokushisa. Ukucinywa kwe-high-frequency kungaqinisa ubuso ngesikhathi esifushane, ukwakheka kwekristalu kuhle kakhulu, futhi ukuguqulwa kwesakhiwo kuncane. Yiba mncane.
