Kodi kasinthasintha liwiro la pakati waukulu wa Kutseka chida chamakina kusankhidwa?

Kusankhidwa kwa liwiro la kasinthasintha pamene workpiece yozimitsidwa imatenthedwa. Kuchokera ku kufanana kwa kutentha kwa workpiece, kuthamanga kwachangu kozungulira, kuchepa kwa kutentha kwa kutentha komwe kumayambitsidwa ndi kusiyana kosiyana pakati pa inductor ndi workpiece. Zida zamakina zozimitsira koyambirira nthawi zambiri zimayika liwiro la 60-300 / min. Zida zina zamakina zimakhala ndi liwiro losasunthika, ndipo zida zina zamakina zimagwiritsa ntchito kusintha kwa liwiro lopanda masitepe, komwe wogwiritsa ntchito angasankhe mwakufuna kwake. Komabe, zida zina zamakina zimakhala ndi liwiro lotsika kwambiri chifukwa cha zinthu zina. Mwachitsanzo, crankshaft magazini makina kuumitsa, chachikulu magazini liwiro nthawi zambiri 60r / mphindi, pamene kulumikiza ndodo magazini liwiro ndi 30r / mphindi. Izi ndichifukwa choti khosi lolumikizira limazungulira pamakina owuma kudzera pamakina olowera (ndodo zinayi zolumikizidwa). Ngati liwiro lozungulira liri lothamanga kwambiri, sensa ya theka la mphete silingathe kusuntha mosasunthika kudutsa magaziniyo, kotero imatha kuyendayenda pamtunda wochepa wa 30r / min. Kuthamanga kumeneku sikoyenera kutenthetsa magazini. Magazini yayikulu imagwiritsa ntchito 60r / Min ndichifukwa chake mapangidwe ake amatha kukhala osavuta chifukwa chogwiritsa ntchito ma mota awiri-liwiro.

Pali mkangano woti kusankha kwa liwiro kuyenera kuganiziridwa pakuwotcha kwa workpiece. Chogwirira ntchito chimayenera kuzunguliridwa nthawi zosachepera 10 pakuwotchera kuti zitsimikizire kutentha kofananira kuzungulira kwa chogwiriracho. Malinga ndi kuwerengetsera uku, nthawi yotenthetsera yotenthetsera ya ntchito wamba nthawi zambiri imakhala pakati pa 5-10s. Ngati ndi 5s mpaka 10 kusintha, ndi 120r / min. Ngati ndi 10s mpaka 10 kusintha, liwiro ndi 60r / min.

Ndi chitukuko cha kuthamanga kwa kutentha kwa induction, kwa ma giya otenthetsera amtundu wapawiri-frequency, nthawi yotentha ya magiya yafupikitsidwa kukhala 0.1-0.2s. Choncho, zofunikira pa liwiro la workpiece zikuchulukirachulukira, ndipo liwiro lapamwamba la spindle la zida zina zozimitsa makina afikira anthu 1600 / min. Pakadali pano, ndizosowa kuti liwiro lazida zamakina ozimitsira limafikira 600r / min. Kuphatikiza apo, liwiro la kasinthidwe ka workpiece limakhudzanso kuzizira. Kwa magiya ndi ma spline shafts, kuzimitsa ndi kuziziritsa nthawi zambiri amagwiritsa ntchito njira yamadzimadzi yopopera. Kuzungulira kwa workpiece ndikothamanga kwambiri, ndipo madzi ozimitsira ndi osakwanira kuziziritsa mbali imodzi ya dzino. Choncho, liwiro la chida chozimitsa makina akadali 600r / min kapena 300r / min monga malire apamwamba. Kuphatikiza apo, ndikofunikira kupanga zida zamakina kapena zamagetsi zomwe zimatha kuchepetsa liwiro la chogwiriracho pakanthawi kutentha kumalizidwa, kuti chogwiriracho chizitha kuzungulira mwachangu kuti chikwaniritse Kutentha kofananira, komanso kuzungulira pang’onopang’ono kukwaniritsa zofunikira za yunifolomu. kuziziritsa kwa zida zogwirira ntchito.
