Kusiyana Kuthetsa pafupipafupi ndi kuzimitsa kwapafupipafupi

1. Kodi kulowetsedwa ndikutani

Kuzimitsa kwapafupipafupi kumagwiritsidwa ntchito pozimitsa pamwamba pazitsulo zazitsulo. Imeneyi ndi njira yachitsulo yotenthetsera madzi yomwe imapangitsa kuti pakapangidwe kazitsulo kali pantchitoyo, iwatenthe msanga pamwamba pa gawolo, kenako ndikuyimitsa mwachangu.

Chachiwiri, kutseka kwapafupipafupi ndi kotani

Kutseketsa kwapakatikati ndikuyika zida zachitsulo mu coil induction, coil induction imapatsidwa mphamvu kuti ipange gawo lina lamagetsi yamagetsi, ndipo mphamvu zina zomwe zimapangidwira zimayikidwa mu gawo lachitsulo. Chifukwa chakhungu, zomwe zimachitika pakadali pano zimangokhala pamwamba pazitsulo, motero kutentha kwapamwamba Kwambiri ndikoziziritsa kwamadzi kapena kuziziritsa kwina pansi pamiyala yoyambira. Popeza kutentha ndi kuzizira kumangoyang’ana pamwamba, kusintha kwake kumakhala koonekeratu, pomwe kusinthidwa kwamkati sikuli kwenikweni, ndipo kumatha kukhala ndi mphamvu yapadera yochizira kutentha.

Chachitatu, kusiyana pakati pa kuzimitsa kwapafupipafupi ndi kuzimitsa kwapafupipafupi

Kutseka kwapafupipafupi ndi kuzimitsa kwapafupipafupi zonsezo ndi mtundu waukadaulo wapamwamba wothandizira kutentha. Onsewa amagwiritsa ntchito pafupipafupi (kapena pafupipafupi, pafupipafupi, pamagetsi) kuti atenthe mwachangu pamwamba pazitsulo ndipo nthawi yomweyo amaziziritsa.

Mfundo yogwirira ntchito yolimbitsa pafupipafupi ndiyofanana ndi yowuma kwapafupipafupi, yomwe ndi mfundo yotenthetsera: ndiko kuti, chojambuliracho chimayikidwa mu inductor, yomwe nthawi zambiri imakhala chubu yopanda pake yamkuwa yokhala ndi pafupipafupi kapena kusinthasintha kwaposachedwa kwamakono (1000-300000Hz kapena kupitilira apo). Maginito osinthasinthawo amachititsa kuti pakhale mafupipafupi ofanana pantchitoyo. Kugawidwa kwamakono opangira ntchitoyi sikungafanane. Ndi yolimba pamtunda koma mkati mwake ndi yofooka. Ili pafupi 0 pachimake. Gwiritsani ntchito khungu ili, Pamwamba pa cholembedwacho chitha kutenthedwa mwachangu, ndipo kutentha kwapamwamba kukwera mpaka 800-1000 ℃ mkati mwa masekondi ochepa, pomwe kutentha kwa pachimake kudzawonjezeka pang’ono

Komabe, pakukonzekera kutentha, magawidwe azomwe zimapangidwira pantchitoyo sakhala yunifolomu, ndipo zotenthetsera zomwe zimapangidwa ndi ma frequency osiyanasiyana ndizosiyana:

1. Kuthetsa pafupipafupi

Ma frequency apano ndi 100 ～ 500 kHz

Osaya osakhazikika wosanjikiza (1.5 ~ 2mm)

Kuuma kwambiri

Chogwirira ntchito sikophweka kuyikonza

Mapindikidwe ang’onoang’ono

Kuthetsa kwabwino kwabwino

zokolola zambiri

Zokwanira magawo omwe amagwira ntchito pamavuto, monga magiya ang’onoang’ono ndi shafts (zida zomwe zimagwiritsidwa ntchito ndi 45 # chitsulo, 40Cr)

2. Kuthetsa pafupipafupi

Ma frequency apano ndi 500 ～ 10000 Hz

Nato olimba wosanjikiza (3 ~ 5mm)

Zokwanira magawo omwe amatha kuponderezedwa komanso kupanikizika, monga ma crankshafts, magiya akulu, makina opangira makina, ndi zina zambiri (Zipangizo zomwe zimagwiritsidwa ntchito ndizitsulo 45, 40Cr, 9Mn2V ndi ductile

Mwachidule, kusiyana kwakukulu pakati pa kutsekeka kwapafupipafupi ndi kuzimitsa kwapafupipakati ndikumasiyana kotentha kotentha. Kuzimitsa kwamafupipafupi kumatha kuumitsa nthaka munthawi yochepa. Kapangidwe kama kristalo ndiwabwino kwambiri ndipo mawonekedwe ake ndi ochepa. Kupsinjika kwapakatikati kwapafupipafupi kumakhala kocheperako kuposa kwamphamvu kwambiri. .
