Impahla yepayipi lensimbi engenamthungo: Ipayipi lensimbi elingenamthungo lenziwe ngensimbi yensimbi noma ishubhu eliqinile ngokubhoboza libe yishubhu elimahhadla, bese liyashisa liyagoqwa, ligoqeke elibandayo noma lidonswe ngokubanda. Izinto ngokuvamile zenziwe ngensimbi ye-carbon ephezulu efana ne-10,20, 30, 35,45, insimbi ephansi ye-alloy yesakhiwo njenge16Mn, 5MnV noma insimbi yengxubevange efana ne-40Cr, 30CrMnSi, 45Mn2, 40MnB ngokuginqika okushisayo noma okubandayo. Amapayipi angenamthungo enziwe ngensimbi enekhabhoni ephansi efana no-10 no-20 asetshenziselwa ikakhulukazi amapayipi okulethwa koketshezi.
Ngokuvamile, inqubo yokukhiqiza amapayipi ensimbi engenamthungo ihlukaniswe yaba izinhlobo ezimbili: inqubo yokudweba ebandayo kanye nenqubo yokugoqa eshisayo. Okulandelayo ukubuka kabanzi kwenqubo yokugeleza kwamapayipi ensimbi adonswa ngokubanda angenamthungo kanye namapayipi ensimbi angenamthungo agingqiwe ashisayo:
Inqubo yepayipi lensimbi elidonswa ngokubanda (eligoqekayo) elingenamthungo: ukulungiswa nokuhlolwa kwe-tube billet → ukushisisa kweshubhu ye-billet → ukubhobozwa → ukugoqa kwepayipi → ukushisa kabusha kwepayipi → ubukhulu (ukunciphisa) ubukhulu → ukwelashwa kokushisa → ukuqondisa kweshubhu okuqediwe → ukuqeda → ukuhlola (okungeyona -okulimazayo, ngokomzimba namakhemikhali, ukuhlolwa kwebhentshi) → ukugcinwa
Amabhilidi epayipi ensimbi angenamthungo agoqelwe abandayo kumele aqale agingqike ngokuqhubekayo, futhi ukuhlolwa kokulinganisa kufanele kwenziwe ngemva kokukhishwa. Uma kungekho ukuqhekeka kwempendulo ebusweni, ishubhu eliyindilinga kufanele lisikwe ngomshini wokusika bese lisikwa libe amabhilidi anobude obungaba imitha eyodwa. Bese ufaka inqubo yokudonsa. I-Annealing kufanele ifakwe emanzini ane-asidi. Ngesikhathi sokuvuna, qaphela ukuthi kukhona inani elikhulu lama-bubbles ebusweni. Uma kukhona inani elikhulu lama-bubbles, kusho ukuthi ikhwalithi yepayipi yensimbi ayihlangabezani nezindinganiso ezihambisanayo.
Inqubo yepayipi lensimbi eligoqiwe elishisayo (elikhishiwe) elingenamthungo: ishubhu eliyindilinga billet → ukushisa → ukubhobozwa → ukugoqeka okugoqiwe okunamasondo amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukususwa kweshubhu → ubukhulu (noma ukunciphisa) ubukhulu → ukupholisa → ishubhu le-billet → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukutholwa kwamaphutha) → ukumaka → isitoreji
Ukugoqa okushisayo, njengoba negama lisho, kunokushisa okuphezulu kwesiqephu esigoqiwe, ngakho-ke ukumelana ne-deformation kuncane futhi inani elikhulu le-deformation lingafinyelelwa. Isimo sokulethwa kwamapayipi ensimbi engenamthungo agingqiwe ashisayo ngokuvamile ayashiswa futhi aphathwe ngokushisa ngaphambi kokulethwa. I-tube eqinile iyahlolwa futhi amaphutha angaphezulu asusiwe, anqunywe ubude obudingekayo, agxile ekugcineni kokuphela kwe-tube enezimbobo, bese ethunyelwa esithandweni sokushisa ukuze kushiswe futhi kufakwe i-perforator. Ngenkathi ibhoboza, iyajikeleza futhi iya phambili ngokuqhubekayo. Ngaphansi kwesenzo sama-roller nekhanda, i-cavity yakha kancane kancane ngaphakathi kwe-tube, ebizwa ngokuthi i-tube rough. Ngemuva kokuthi ishubhu lisusiwe, lithunyelwa emshinini wokugoqa we-automatic ukuze liqhubeke ligoqeka, bese ukujiya kodonga kulungiswa umshini wokulinganisa, futhi ububanzi bunqunywa umshini wokulinganisa ukuze uhlangabezane nezidingo zokucaciswa. Ngemuva kokwelashwa kwe-hot rolling, ukuhlolwa kwe-perforation kufanele kwenziwe. Uma ububanzi be-perforation bukhulu kakhulu, kufanele buqondiswe futhi bulungiswe, futhi ekugcineni bubhalwe futhi bubekwe endaweni yokugcina.
Ukuqhathaniswa kwenqubo yokudweba okubandayo kanye nenqubo yokuginqika okushisayo: Inqubo yokugoqa ebandayo iyinkimbinkimbi kakhulu kunenqubo yokuginqika eshisayo, kodwa ikhwalithi ephezulu, ukubukeka, nokunemba kobukhulu bamapuleti ensimbi agoqelwe ngokubanda kungcono kunalawo amapuleti aginqike ashisayo, futhi ukushuba komkhiqizo kungaba mncane.
Usayizi: Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe elishisayo ngokuvamile likhulu kuno-32mm, futhi ukujiya kodonga kungu-2.5-200mm. Ububanzi bangaphandle bepayipi lensimbi eligoqelwe ngokubanda elingenamthungo bungaba ngu-6mm, ukujiya kodonga bungafinyelela ku-0.25mm, ububanzi obungaphandle bepayipi elinezindonga ezincane bungaba ngu-5mm, futhi ukujiya kodonga kungaphansi kuka-0.25mm ( ngisho ngaphansi kuka-0.2mm), futhi ukunemba kobukhulu bokugoqa okubandayo kuphakeme kunalokho kokuginqika okushisayo.
Ukubukeka: Nakuba ubukhulu bodonga bepayipi lensimbi eligoqeke elibandayo ngokuvamile lincane kunepayipi lensimbi engenamthungo eligoqwe elishisayo, indawo engaphezulu ibukeka ikhanya kunepayipi lensimbi engenamthungo enezindonga eziqinile, indawo engaphezulu ayimbi kakhulu, futhi I-diameter ayinawo ama-burrs amaningi kakhulu.
Isimo sokulethwa: Amapayipi ensimbi agoqelwe ngokushisayo alethwa esimweni sokugoqwa okushisayo noma esiphethwe ngokushisa, futhi amapayipi ensimbi agoqeke abandayo alethwa esimweni esiphethwe ukushisa.
