Ukucinywa kokungeniswa kuyinqubo yokucisha esebenzisa umthelela oshisayo okhiqizwa amandla amanje okungenisa edlula efojini ukuze kushise indawo engaphezulu nengxenye yendawo yokubumba kuya kumazinga okushisa okucisha, okulandelwa ukupholisa okusheshayo. Ngesikhathi sokucisha, i-forging ifakwa kunzwa yendawo yethusi futhi ixhunywe kumsinga oshintshanayo wefrikhwensi engaguquki ukuze kukhiqizwe induction ye-electromagnetic, okuholela kumanje owenziwe endaweni yokufoja ephambene neyamanje kukhoyili yokungeniswa. Iluphu evaliwe eyakhiwe yilo msinga obangelwayo eduze kwendawo yokuqamba ibizwa ngokuthi i-eddy current. Ngaphansi kwesenzo se-eddy current kanye nokumelana kokuzenzela, amandla kagesi aguqulwa abe amandla ashisayo ebusweni bokubumba, okubangela ukuthi ubuso bushise ngokushesha kuze kufike ukuchichima kokucisha, emva kwalokho ukubunjwa kwenziwa ngokushesha futhi ngokushesha. ipholile ukuze kuzuzwe inhloso yokucisha indawo.
Isizathu sokuthi ama-eddy currents angafinyelela ukushisisa okungaphezulu kunqunywa izici zokusabalalisa zamanje ezishintshayo ku-conductor. Lezi zici zihlanganisa:
- Umphumela Wesikhumba:
Uma i-direct current (DC) idlula ku-conductor, ukuminyana kwamanje kufana nesigaba esiphambanayo sikakhondakta. Nokho, lapho ukushintshashintsha kwamanje (AC) kudlula, ukusabalalisa kwamanje kuyo yonke ingxenye yekhondatha akulingani. Ukuminyana kwamanje kuphezulu endaweni yekhondatha futhi kuphansi phakathi nendawo, ukuminyana kwamanje kuncipha kakhulu ukusuka phezulu kuya maphakathi. Lesi simo saziwa ngokuthi umphumela wesikhumba we-AC. Lapho imvamisa ye-AC iphakeme, umphumela wesikhumba ugqama kakhulu. Ukucima ukushisisa kwe-induction kusebenzisa lesi sici ukufeza umphumela oyifunayo.
- Umthelela wokusondela:
Lapho ama-conductor amabili asondelene edlula ku-current, uma indlela yamanje ifana, amandla abuyele emuva ohlangothini oluseduze lamakhondakta amabili makhulu kakhulu ngenxa yokusebenzisana kwezizibuthe ezishintshanayo ezikhiqizwe yiwo, futhi yamanje iqhutshwa uhlangothi olungaphandle lwe-conductor. Ngokuphambene nalokho, lapho isiqondiso samanje siphambene, i-current iqhutshelwa ohlangothini oluseduze lwabaqhubi ababili, okungukuthi, ukugeleza kwangaphakathi, lesi simo sibizwa ngokuthi umphumela wokusondeza.
Ngesikhathi sokushisa kwe-induction, i-current induction on the forging ihlale ibheke kolunye uhlangothi lwamanje eringini yokungeniswa, ngakho-ke i-current induction ring igxile ekugelezeni kwangaphakathi, futhi okwamanje ku-heated forging etholakala eringini yokungeniswa. igxile ebusweni, okuwumphumela womphumela wokusondela kanye nomphumela wesikhumba obekwe phezulu.
Ngaphansi kwesenzo somthelela oseduze, ukusatshalaliswa kwamanje owenziwe ebusweni be-forging kufana kuphela uma igebe phakathi kwekhoyili yokungeniswa kanye ne-forging lilingana. Ngakho-ke, i-forging kumele ijikelezwe ngokuqhubekayo ngesikhathi sokushisa kwe-induction ukuze kuqedwe noma kuncishiswe ukungalingani kokushisa okubangelwa igebe elingalingani, ukuze uthole isendlalelo sokushisa esifanayo.
Ngaphezu kwalokho, ngenxa yomphumela oseduze, ukuma kwendawo eshisayo ekufakeni kuhlale kufana nokuma kwekhoyili yokungeniswa. Ngakho-ke, lapho wenza ikhoyili ye-induction, kuyadingeka ukwenza ukwakheka kwayo kufane nesimo sendawo yokushisa ye-forging, ukuze kuzuzwe umphumela ongcono wokushisa.
- Umthelela Wokuzungeza:
Lapho ukushintshana kwamandla kudlula ku-conductor omise okweringi noma we-helical, ngenxa yesenzo sendima kazibuthe eshintshanayo, ukuminyana kwamanje endaweni engaphandle yekhondakta kuyehla ngenxa yamandla e-electromotive angemuva ayazishayelayo, kuyilapho indawo engaphakathi iringi ithola ukuminyana okuphezulu kakhulu kwamanje. Lesi simo saziwa ngokuthi umphumela wokujikeleza.
Umthelela wokujikeleza ungathuthukisa ukusebenza kahle kokushisisa kanye nesivinini lapho kushisisa indawo engaphandle yesiqephu esifojiwe. Kodwa-ke, akulungile ukushisa izimbobo zangaphakathi, njengoba umphumela wokujikeleza ubangela ukuthi i-current in inductor isuke ebusweni besiqephu esibunjiwe, okuholela ekunciphiseni kakhulu ukusebenza kahle kokushisa kanye nesivinini sokushisa esihamba kancane. Ngakho-ke, kuyadingeka ukufaka izinto kazibuthe ezinokungena okuphezulu ku-inductor ukuthuthukisa ukusebenza kahle kokushisa.
Uma sikhulu isilinganiso sokuphakama kwe-axial ye-inductor kuya kububanzi bendandatho, umphumela wokujikeleza ubonakala kakhulu. Ngakho-ke, i-cross-section ye-inductor ingcono kakhulu eyenziwe unxande; umumo ongunxande ungcono kunesikwele, futhi umumo oyindilinga yiwona omubi kakhulu futhi kufanele ugwenywe ngangokunokwenzeka
- Umthelela we-engeli ebukhali:
Lapho izingxenye eziphumile ezinamakhona acijile, imiphetho enqenqemeni kanye nerediyasi encane yokugoba kushisiswe kunzwa, ngisho noma igebe phakathi kwenzwa kanye ne-forging lilingana, ukuminyana komugqa wensimu kazibuthe emakhoneni acijile kanye nezingxenye eziphumile zokufogela zikhulu. , ukuminyana kwamanje okuthosiwe kukhulu, isivinini sokushisa siyashesha, futhi ukushisa kugxilile, okuzokwenza lezi zingxenye zishise futhi zishise. Lesi simo sibizwa ngokuthi i-Sharp Angle effect.
Ukuze ugweme umphumela we-Engeli ebukhali, lapho uklama inzwa, igebe phakathi kwenzwa kanye ne-engeli ebukhali noma ingxenye ye-convex ye-forging kufanele inyuswe ngokufanelekile ukuze kuncishiswe ukugxiliswa komugqa wamandla kazibuthe lapho, ukuze isivinini sokushisisa futhi izinga lokushisa lokuqamba yonke indawo lifana ngangokunokwenzeka. Amakhona abukhali kanye nezingxenye eziqhamukayo zokubunjwa nazo zingashintshwa zibe ngamakhona ezinyawo noma ama-chamfers, ukuze kutholakale umphumela ofanayo.
