Hordhac:

Tuubooyin aan kala go 'lahayn waa nooc ka mid ah walxo bir ah oo sax ah ka dib sawir qabow ama duubid kulul.Sababtoo ah ma jiro lakab oksaydh ah oo ku yaal gidaarada gudaha iyo dibadda ee tuubada saxda ah ee saxda ah, [1] cadaadis sare oo aan lahayn dareere, saxsanaan sare, dhammayn sare, laabasho qabow oo aan qalloocin, dhalaalid, fidsan dildilaac la'aan iyo wixii la mid ah, inta badan waa la isticmaalaa. si loo soo saaro qaybaha pneumatic ama hydraulic, sida dhululubada ama dhululubada, kuwaas oo noqon kara kuwo aan kala go 'lahayn.Halabuurka kiimikaad ee tuubbada aan tol lahayn waa kaarboon C, Silicon Si, manganese Mn, sulfur S, fosfooraska P, chromium Cr

Tuubooyin aan xidhnayn oo la daboolay ayaa qaata tignoolajiyada farsamaynta

Tuubbada la jeexjeexay ee bilaa tolmoon waxaa lagu farsameeyaa giringijin.Sababtoo ah cadaadiska cadaadiska ee hadhaaga ah ee lakabka dusha sare, waxaa waxtar leh in la xiro dildilaaca yar ee dusha sare iyo ka hortagga fidinta nabaadguurka.Waxay hagaajin kartaa caabbinta daxalka dusha sare waxayna dib u dhigi kartaa jiilka ama ballaarinta dildilaaca daalka, si loo hagaajiyo xoogga daalka ee tuubada birta ee quilted.Samaynta duubista, lakab adag oo shaqaynaysa qabow ayaa laga sameeyay dusha rogmada, taas oo yaraynaysa qallafsanaanta laastikada iyo caagagga ee dusha xidhiidhka ee lammaanaha wax shiididda, sidaas awgeed waxay hagaajinaysaa adkaysiga xidhashada ee gidaarka gudaha ee tuubada birta ah ee birta ah iyo ka fogaanshaha gubashada. ay keento shiidis.Ka dib rogid, yaraynta qallafsanaanta dusha sare waxay hagaajin kartaa hantida ku habboon.

Mashiinka duubista waa nooc ka mid ah mashiinnada chip-ka bilaashka ah.Heerkulka caadiga ah, qallafsanaanta caaga ah ee birta waxaa loo isticmaalaa in lagu sifeeyo qallafsanaanta microscopic ee dusha workpiece si loo gaaro ujeedada beddelka qaab dhismeedka dusha, sifooyinka farsamada, qaabka iyo cabbirka.Sidaa darteed, habkani wuxuu gaari karaa labada ujeedo ee nadiifinta iyo xoojinta isku mar, kaas oo aan awoodin inuu sameeyo shiiditaan.

Si kastaba ha ahaatee nooca habka loo isticmaalo si loo farsameeyo, had iyo jeer waxaa jiri doona convex wanaagsan iyo calaamado middi aan sinnayn on dusha qaybaha, iyo ifafaale ee sare iyo dooxooyinka.

Mabda'a processing Rolling: Waa nooc ka mid ah processing dhamaystirka cadaadiska, waa isticmaalka biraha ee heerkulka caadiga ah ee heerkulka caadiga ah ee sifooyinka caag qabow, isticmaalka qalabka rogid si ay u sameeyaan cadaadis gaar ah on dusha workpiece ah, si ay dusha workpiece caag biraha ah. qulqulka, buuxi haraaga asalka ah ee hadhaagii hoose ee weel, oo gaadho heerka qallafsanaanta dusha workpiece la dhimay.Sababo la xiriira qallafsanaanta caagga ah ee biraha duudduuban, unugyada dusha qabow qallafsanaanta iyo khafiifinta hadhuudhka, formation of fiber cufan, iyo samaynta lakabka stress haraaga, engegnaanta iyo xoogga, sidaas hagaajinta iska caabin xirashada, iska caabin daxalka iyo waafaqid ee dusha workpiece.Rolling waa habka makiinado caag ah oo aan goyn.

Tuubooyin aan kala go 'lahayn oo la dajiyay dhowr faa'iidooyin:

1, wanaaji qallafsanaanta dusha sare, qallafsanaanta asal ahaan waxay gaari kartaa Ra≤0.08µ m ama wax ka badan.

2, wareega saxda ah, ellipticity wuxuu noqon karaa wax ka yar 0.01mm.

3, hagaajinta qallafsanaanta dusha sare, qallafsanaanta xoogga waa la tirtiraa, adkaanta waxay kordhisaa HV≥4 °

4, ka dib markii la farsameeyo lakabka walbahaarka haraaga, hagaajin xoogga daalka 30%.

5, hagaajinta tayada taam, yaraynta xirashada, kordhiso nolosha adeegga ee qaybaha, laakiin kharashka processing ee qaybaha waa la dhimay.
