Izinto zombhobho wensimbi ezingenamthungo: Ipayipi lensimbi elingenamthungo lenziwa nge-ingot yensimbi noma i-billet yeshubhu eqinile ngokubhoboza ibe yishubhu eliqinile, bese ligoqwa ngokushisa, ligoqwe ngokubandayo noma lidonswe ngokubandayo. Izinto zombhobho ngokuvamile zenziwe ngensimbi yekhabhoni esezingeni eliphezulu njenge-10,20, 30, 35,45, insimbi yesakhiwo ephansi ye-alloy efana ne-16Mn, 5MnV noma insimbi ye-alloy efana ne-40Cr, 30CrMnSi, 45Mn2, 40MnB ngokugoqa okushisayo noma ngokugoqa okubandayo. Amapayipi angenamthungo enziwe ngensimbi ephansi yekhabhoni efana ne-10 kanye ne-20 asetshenziswa kakhulu kumapayipi okulethwa koketshezi.
Ngokuvamile, inqubo yokukhiqiza amapayipi ensimbi angenamthungo ihlukaniswe izinhlobo ezimbili: inqubo yokudweba ebandayo kanye nenqubo yokugoqa eshisayo. Okulandelayo umbono jikelele wokuhamba kwenqubo yamapayipi ensimbi angenamthungo adonswa ebandayo kanye namapayipi ensimbi angenamthungo adonswa eshisayo:
Inqubo yepayipi lensimbi engenamthungo edonswa ngokubandayo (egoqwe ngokubandayo): ukulungiswa nokuhlolwa kwe-tube billet → ukushisa kwe-tube billet → ukubhoboza → ukugoqwa kwepayipi → ukufudumeza kabusha ipayipi lensimbi → ubukhulu (ukunciphisa) ububanzi → ukwelashwa kokushisa → ukuqondisa ipayipi okuqediwe → ukuqeda → ukuhlolwa (okungonakalisi, okungokomzimba namakhemikhali, ukuhlolwa kwebhentshi) → isitoreji
Ama-billet ensimbi engenamthungo aqoqwe ngokubandayo kumele aqale aqhutshwe ngokugoqa okuqhubeka kathathu, futhi ukuhlolwa kosayizi kumele kwenziwe ngemuva kokukhipha. Uma kungekho ukuqhekeka kokuphendula ebusweni, ithubhu eliyindilinga kumele lisikwe ngomshini wokusika bese lisikwa libe ama-billets anobude obungaba yimitha elilodwa. Bese ungena enkambisweni yokubopha. Ukubopha kumele kufakwe uketshezi olune-asidi. Ngesikhathi sokubopha, qaphela ukuthi ngabe kukhona yini amabhamuza amaningi ebusweni. Uma kunenqwaba yamabhamuza, kusho ukuthi ikhwalithi yepayipi lensimbi ayihlangabezani nezindinganiso ezifanele.
Inqubo yepayipi yensimbi engenamthungo egoqwe ngokushisa (ekhishwe): i-billet yeshubhu eliyindilinga → ukushisa → ukubhoboza → ukugoqa okugobile okunemiphetho emithathu, ukugoqa okuqhubekayo noma ukukhishwa kweshubhu → ukususwa kweshubhu → ubukhulu (noma ukunciphisa) ububanzi → ukupholisa → ishubhu ye-billet → ukuqondisa → ukuhlolwa kokucindezela kwamanzi (noma ukutholwa kwamaphutha) → ukumaka → isitoreji
Ukugoqa okushisayo, njengoba igama lisho, kunokushisa okuphezulu kwengxenye egoqiwe, ngakho-ke ukumelana nokugoqa kuncane futhi inani elikhulu lokugoqa lingatholakala. Isimo sokulethwa kwamapayipi ensimbi angenamthungo agoqiwe ashisayo ngokuvamile agoqiwe ashiswe futhi aphathwe ngokushisa ngaphambi kokulethwa. Ishubhu eliqinile liyahlolwa bese kususwa amaphutha obuso, anqunywe abe ubude obudingekayo, agxile ebusweni bokugcina bengxenye ebhobhile yeshubhu, bese ethunyelwa esithandweni sokushisa ukuze kufudunyezwe futhi kubhobhiswe ku-perforator. Ngenkathi ibhobhile, iyajikeleza futhi iqhubeke phambili ngokuqhubekayo. Ngaphansi kwesenzo sama-roller nekhanda, kwakheka umgodi kancane kancane ngaphakathi kweshubhu, okubizwa ngokuthi ishubhu elibi. Ngemva kokuba ishubhu lisusiwe, lithunyelwa emshinini wokugoqa ishubhu ozenzakalelayo ukuze liqhubeke nokugoqa, bese ubukhulu bodonga bulungiswa ngumshini wokulinganisa, bese ububanzi bunqunywa ngumshini wokulinganisa ukuze kuhlangatshezwane nezidingo zemininingwane. Ngemuva kokwelashwa kokugoqa okushisayo, kufanele kwenziwe ukuhlolwa kokugoqa. Uma ububanzi bokugoqa bukhulu kakhulu, kufanele buqondiswe futhi bulungiswe, bese ekugcineni bufakwe ilebula bese bugcinwa.
Ukuqhathaniswa kwenqubo yokudweba ebandayo kanye nenqubo yokugoqa eshisayo: Inqubo yokugoqa ebandayo iyinkimbinkimbi kakhulu kunenqubo yokugoqa eshisayo, kodwa ikhwalithi yobuso, ukubukeka, kanye nokunemba kobukhulu bamapuleti ensimbi agoqa ebandayo kungcono kunalawo amapuleti agoqa eshisayo, futhi ukujiya komkhiqizo kungaba kuncane.
Usayizi: Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe ngokushisa ngokuvamile bukhulu kuno-32mm, kanti ubukhulu bodonga bungu-2.5-200mm. Ububanzi bangaphandle bepayipi lensimbi elingenamthungo eligoqwe ngokushisa bungaba ngu-6mm, ubukhulu bodonga bungaba ngu-0.25mm, ububanzi bangaphandle bepayipi elinezindonga ezincane bungaba ngu-5mm, kanti ubukhulu bodonga bungaphansi kuka-0.25mm (ngisho nangaphansi kuka-0.2mm), kanti ukunemba kobukhulu bepayipi elibandayo kuphakeme kunokwepayipi elishisayo.
Ukubukeka: Nakuba ubukhulu bodonga lwepayipi lensimbi engenamthungo eligoqwe ngokubandayo ngokuvamile buncane kunobombhobho wensimbi engenamthungo eligoqwe ngokushisayo, ubuso bubukeka bukhanya kakhulu kunepayipi lensimbi engenamthungo eligoqwe ngokushisayo eligoqwe ngokushisayo, ubuso abuqinile kakhulu, futhi ububanzi abunawo ama-burrs amaningi kakhulu.
Isimo sokulethwa: Amapayipi ensimbi aguqayo ashisayo alethwa esimweni sokuguqayo noma sokuphathwa ngokushisa, kanti amapayipi ensimbi aguqayo abandayo alethwa esimweni sokuphathwa ngokushisa.
