Iindlela zokuVelisa kunye nokuVelisa
Ngokweendlela ezahlukeneyo zokuvelisa, inokwahlulwa ibe ityhubhu eqengqelekayo eshushu, ityhubhu eqengqelekayo ebandayo, ityhubhu etsalwa ngokubanda, ityhubhu yokukhupha njalo njalo.
1.1 Imibhobho eshushu eqengqelekayo engenamthungo iveliswa ngokubanzi kwiiseti zokuqengqeleka kwemibhobho.Umbhobho oqinileyo ongenanto uhlolwe kwaye ucinywe iziphene zomhlaba, unqunyulwe ubude obufunekayo, ugxininise kwi-perforated ekupheleni kobuso betyhubhu engenanto, kwaye emva koko ithunyelwe kwiziko lokufudumeza ukufudumeza, kunye ne-perforated kumatshini we-punch.Ekugqobhozeni kwangaxeshanye ujikelezo oluqhubekayo naphambili, phantsi kwentshukumo yokuqengqeleka kunye nomphezulu, umbhobho ongenanto ngokuthe ngcembe wenze umngxuma, obizwa ngokuba yityhubhu yoboya.Emva koko ithunyelwa kumbhobho wokusila ukuze uqhubeke uqengqeleka.Okokugqibela, ubukhulu bodonga lomatshini wonke buhlengahlengiswa, kwaye umatshini wokulinganisa uhlengahlengiswa ukuhlangabezana neemfuno ezichaziweyo.Yindlela ephucukileyo yokuvelisa ityhubhu yentsimbi engenamthungo eshushu eqengqelekayo kunye neseti yetyhubhu eqengqelekayo.
1.2 Ukuba ufuna ukufumana iityhubhu ezingenamthungo ezinobukhulu obuncinci kunye nomgangatho ongcono, kufuneka usebenzise ukuqengqeleka okubandayo, umzobo obandayo okanye indibaniselwano yeendlela zombini.I-Cold rolling idla ngokuqhutyelwa kwi-mill-high-high.Umbhobho wensimbi ugqitywe kwi-annular pass equkethe i-groove ejikelezayo enecandelo eliguquguqukayo kunye ne-conical top emileyo.Umzobo obandayo udla ngokuqhutywa kwi-0.5 ~ 100T ngetsheyini enye okanye umatshini wokuzoba ngekhonkco eliphindwe kabini.
1.3.Indlela ye-Extrusion: I-tube evuthayo engenanto ifakwe kwi-cylinder ye-extrusion evaliweyo, kwaye intonga ene-perforated ihamba kunye nentonga ye-extrusion ukuze ikhuphe iindawo ezikhutshiweyo ukusuka kumngxuma wokufa omncinci.Le ndlela inokuvelisa umbhobho wentsimbi wedayamitha encinci.
