Ukucima i-frequency ephezulu yinkqubo yokuqinisa umphezulu esebenzisa i-electromagnetic induction ukufudumeza umphezulu wegiya ngokukhawuleza ukuya kubushushu bayo obubalulekileyo (ngesiqhelo i-800–950°C), kulandele ukucima kwangoko emanzini okanye kwioyile. Oku kubangela umaleko oqinileyo we-martensitic ophucula kakhulu ubulukhuni bomphezulu kunye nokumelana nokuguguleka ngaphandle kokuphazamisa ukuqina kwegiya. Njengoko amashishini efuna ukusebenza okuphezulu kwizicelo ezincinci nezinamandla aphezulu, iigiya ezicinyiweyo rhoqo ziye zaba yinto ebalulekileyo kwizixhobo zeemoto, zemigodi, zamandla, kunye nezichanekileyo.

Iingenelo zoMsebenzi oPhambili

1. Ubunzima obuphezulu kakhulu kunye nokumelana nokunxiba
Ngokufudumeza ngokukhawuleza umphezulu wezinyo legiya nokulicima, umaleko oqinileyo we-martensitic uyenziwa ngobunzima be-HRC 55–62 (obubonakala rhoqo kwintsimbi ye-40Cr okanye ye-42CrMo).

• Ukumelana nokuguguleka kuphucuka ngaphezulu kwama-50%

• Ukuguguleka komphezulu kungama-30–50% kuphela xa kuthelekiswa neegiya eziqhelekileyo ezinganyangwanga

• Ilungele iindawo ezinobunzima obukhulu ezifana neebhokisi zegiya ezinzima kunye noomatshini bokwemba

2. Amandla Okudinwa Aphezulu
Inkqubo yokucima ibangela uxinzelelo oluxineneyo olushiyekileyo kumaleko oqinileyo, nto leyo ethintela ukuqala nokukhula kwemifantu engaphezulu.

• Umda wokudinwa unyuka ngama-20–30%

• Umzekelo, iigiya zeshaft eziphambili zeturbine yomoya ezenziwe nge-42CrMo zinokufikelela kubomi benkonzo beminyaka engama-20

3. Ukuqina Okungundoqo Kugciniwe
Umaleko wangaphandle kuphela oqinisiweyo (ngesiqhelo yi-0.2–5mm), ngelixa umbindi uhlala uthambile kwaye unganyangeki.

• Le propati imbini iqinisekisa ukuqina komphezulu kunye nokumelana nokuqhekeka phantsi kwemithwalo yoxinzelelo

• Isetyenziswa kakhulu kwiigiya zee-axle zeemoto kunye nezinto ezithwele impembelelo

Iingenelo zoLawulo lweNkqubo

1. Ukuqina Okuchanekileyo Kwendawo
Le nkqubo inokujolisa amazinyo ngamanye okanye kwiindawo ezithile kumphezulu wegiya, nto leyo eyenza ifaneleke kwiiprofayili ezintsonkothileyo ezifana neegiya zeplanethi kunye neemilo ezingezizo ezisemgangathweni.

• Ubunzulu obuqinisiweyo buhlengahlengiswa rhoqo, ngamandla, kunye nexesha

• Ivumela unyango oluthile lwesicelo ngokuguquguquka okuncinci

2. Ukusebenza kakuhle kakhulu kunye nokonga amandla
Yonke le nkqubo ithatha imizuzwana embalwa ukuya kwimizuzwana elishumi, inciphisa ukusetyenziswa kwamandla ngama-30% xa kuthelekiswa neendlela zemveli.

• Iyahambelana nemigca yemveliso ezenzekelayo esebenzisa ukuphathwa kwerobhothi

• Ifanelekile kakhulu kwimveliso emikhulu

3. Ukuguquka okuphantsi
Ukufudumala okukufutshane nokukhawulezileyo kunciphisa ukugqwetheka kobushushu.

• Ukuphambuka kobungqukuva kunokulawulwa ngaphakathi kwe-≤0.01 mm kwiigiya ezichanekileyo (umz., iigiya ze-CNC spindle)

• Nangona ukucima nge-laser kunika ukuguquguquka okuncinci nangakumbi, ukucima rhoqo kusetyenziswa kakhulu kwaye kunika ukuguquguquka okukhulu kobunzulu.

Ukusebenza kakuhle kwezinto kunye neendleko

1. Ukuhambelana kwezinto ezibanzi
Isebenza kwiintsimbi zekhabhoni eziphakathi neziphezulu kunye neentsimbi ze-alloy ezinomxholo wekhabhoni ongu-≥0.35%, ezifana ne-S45C, 40Cr, kunye ne-42CrMo.

• Ixhasa uluhlu olubanzi lwezicelo zezixhobo zoshishino

2. Umlinganiselo wokusebenza kweendleko eziphezulu
Ukucima rhoqo kuvumela ukusetyenziswa kwezinto ezingabizi kakhulu (umz., ukuthatha indawo ye-40CrNiMoA), kunciphisa iindleko zezinto ngama-20–30%.

• Umatshini wokulungisa emva konyango awufuneki kakhulu

• Imijikelo emifutshane yemveliso iphucula ukusebenza kakuhle kwemveliso iyonke

Izicelo eziqhelekileyo

Iigiya ezicinywa rhoqo zisetyenziswa kakhulu kumashishini amaninzi ngenxa yokuqina kwazo okuphezulu komphezulu, ukumelana nokuguguleka, kunye namandla okudinwa.icandelo leemoto, zisetyenziswa kwiigiya zokudlulisa ezenziwe ngentsimbi ye-40Cr, ezikwaziyo ukuhlala ukuya kuthi ga kwiikhilomitha ezili-150,000, kunye nakwii-crankshafts zenjini ezisebenza kakuhle.oomatshini abanzima, ezi giya zisetyenziswa kwimigodi ye-crusher shafts apho ubunzima bomphezulu bufikelela kwi-HRC 52 kwaye amandla okudinwa okugoba adlula i-450 MPa.

In izixhobo ezichanekileyo, njengezixhobo zoomatshini be-CNC, iigiya ze-spindle ezenziwe nge-42CrMo zinokusebenza iiyure ezingaphezu kwama-5,000 ngaphandle kokuguquka. Zikwayinxalenye ebalulekileyo kwi-main shafts ze-wind turbine, apho ukuthembeka kunye nobude bexesha kubalulekile. Kwimimandla ye-uthutho lukaloliwe kunye neerobhothi, ukucima i-frequency ephezulu kusetyenziselwa ukuphucula iinkqubo zebhokisi yeegiya kwiitreyini ezihamba ngesantya esiphezulu nakwiirobhothi, kunye nokuqinisa iinkqubo zezikrufu ze-planetary roller.

Imbono yexesha elizayo

Ngenxa yokudibanisa kwayo umphezulu oqinileyo kunye nombindi oqinileyo, iigiya ezicinywa rhoqo azinakutshintshwa xa zinomthwalo omkhulu, isantya esiphezulu, kunye nokusetyenziswa okuchanekileyo. Ngenxa yokuguquguquka kwenkqubo, ukuphambuka okuncinci, kunye nokusebenza kakuhle kweendleko, ihlala isisisombululo esithandwayo kwicandelo leemoto, izixhobo zamandla, kunye noomatshini abachanekileyo.

Uphuhliso lwexesha elizayo luza kugxila koku:

• Ukudibanisa ulawulo lwedijithali ukuze kuphuculwe ngakumbi ukuchaneka kwenkqubo

• Ukuqhubela phambili iinkqubo ezimfutshane, iindlela ezinobuhlobo nendalo zokunciphisa ukusetyenziswa kwamandla kunye nokukhutshwa komoya
