Imathiriyeli yombhobho yentsimbi engenamthungo: Umbhobho wentsimbi ongenamthungo wenziwe ngentsimbi yentsimbi okanye ibhayibhile yetyhubhu eqinileyo ngokugqojozwa kwityhubhu erhabaxa, emva koko ishushu isongwe, iqengqeleke ebandayo okanye izotywe ngokubanda. Izinto eziphathekayo zenziwe ngentsimbi yekhabhoni ekumgangatho ophezulu njenge-10,20, 30, 35,45, i-alloy ephantsi yentsimbi yesakhiwo njenge16Mn, I-5MnV okanye i-alloy steel efana ne-40Cr, i-30CrMnSi, i-45Mn2, i-40MnB ngokuguqa okutshisa okanye ukubanda okubandayo. Imibhobho engenamthungo eyenziwe ngentsimbi ephantsi yekhabhoni efana ne-10 kunye ne-20 isetyenziswa ikakhulu kwimibhobho yokuhambisa ulwelo.
Ngokuqhelekileyo, inkqubo yokuvelisa imibhobho yentsimbi engenamthungo ihlulwe ibe ziindidi ezimbini: inkqubo yokudweba ebandayo kunye nenkqubo eshushu yokuqengqeleka. Oku kulandelayo sisishwankathelo senkqubo yokuhamba kwemibhobho yentsimbi engenamthungo etsalwa ngokubanda kunye nemibhobho yentsimbi engenamthungo eqengqiwe eshushu:
Inkqubo yombhobho yentsimbi epholileyo (ebandayo-yaqengqeleka) engenamthungo: ukulungiswa kunye nokuhlolwa kwetyhubhu yebillet → ukufudumeza ityhubhu yebillet → ukugqobhoza → ukuqengqeleka kwetyhubhu → ukufudumeza kwakhona kombhobho wentsimbi → ubungakanani (ukunciphisa) ubukhulu → unyango lobushushu → ukulungiswa kwetyhubhu egqityiweyo → ukugqiba → ukuhlola -eyonakalisayo, ebonakalayo kunye neekhemikhali, ukuhlolwa kwebhentshi) → ukugcinwa
Iibhilithi zemibhobho yentsimbi epholileyo engenamthungo kufuneka kuqala ifakwe kwi-three-roll eqhubekayo, kwaye iimvavanyo zokulinganisa kufuneka zenziwe emva kokukhutshwa. Ukuba akukho mpendulo eqhekezayo ebusweni, ityhubhu ejikelezileyo kufuneka inqunywe ngumatshini wokusika kwaye unqunywe kwiibhilethi ezinobude obumalunga nemitha enye. Emva koko faka inkqubo yokukhupha. Ukucoca kufuneka kufakwe ulwelo olumuncu. Ngexesha lokukhetha, qaphela ukuba kukho inani elikhulu leebhubhu ebusweni. Ukuba kukho ubuninzi beebhubhu, kuthetha ukuba umgangatho wombhobho wensimbi awuhambisani nemigangatho ehambelanayo.
Inkqubo yombhobho yentsimbi eshushu eqengqelekayo (eyongeziweyo) engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukususwa kwetyhubhu → ubungakanani (okanye ukunciphisa) ubukhulu → ukupholisa → ityhubhu yebhiliti → ukolula → uvavanyo loxinzelelo lwamanzi (okanye ukufumanisa isiphene) → ukuphawula → ugcino
I-Hot rolling, njengoko igama lithetha, linobushushu obuphezulu beqhekeza, ngoko ke ukuchasana kwe-deformation kuncinci kwaye inani elikhulu lokuguqulwa linokufezekiswa. Imeko yokuhanjiswa kweebhobho zentsimbi ezingenamthungo ezishushu ziqengqeleka ngokuqhelekileyo zishushu kwaye ziphathwe ngobushushu phambi kokunikezelwa. I-tube eqinile ihlolwe kwaye iziphene zomhlaba zisuswe, zinqunywe ubude obufunekayo, zijoliswe ekupheleni kobuso bombhobho we-perforated, kwaye emva koko ithunyelwe kwisithando sokufudumala sokufudumala kunye ne-perforated kwi-perforator. Ngelixa i-perforating, iyajikeleza kwaye iqhubela phambili ngokuqhubekayo. Ngaphantsi kwesenzo se-roller kunye nentloko, i-cavity yenza kancane kancane ngaphakathi kwi-tube, ebizwa ngokuba yi-tube rough. Emva kokuba ityhubhu isusiwe, ithunyelwa kumatshini ozenzekelayo wokuqengqeleka ityhubhu ukuze iqhubeleke ngakumbi, emva koko ubukhulu bodonga buhlengahlengiswe ngumatshini wokulinganisa, kwaye ububanzi bumiselwa ngumatshini wokulinganisa ukuhlangabezana neemfuno ezichaziweyo. Emva konyango olushushu, kufuneka kwenziwe uvavanyo lokugqobhoza. Ukuba i-diameter ye-perforation inkulu kakhulu, kufuneka iqondiswe kwaye ilungiswe, kwaye ekugqibeleni ibhalwe kwaye ifakwe kwindawo yokugcina.
Ukuthelekiswa kwenkqubo yokuzoba ebandayo kunye nenkqubo yokuqengqeleka eshushu: Inkqubo yokuqengqeleka ebandayo inzima ngakumbi kunenkqubo yokuqengqeleka eshushu, kodwa umgangatho womphezulu, inkangeleko, kunye nokuchaneka komgangatho weepleyiti zentsimbi eziqengqelekayo zingcono kunezo zamacwecwe ashushu, kwaye ubukhulu bemveliso bunokuba buncinci.
Ubungakanani: Idayamitha yangaphandle yombhobho ongenamthungo oshushu-isolwe ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-200mm. Idayamitha yangaphandle yombhobho wentsimbi engenamthungo eqengqelekayo inokufikelela kwi-6mm, ubukhulu bodonga bungafikelela kwi-0.25mm, ububanzi bangaphandle bombhobho obhityileyo bunokufikelela kwi-5mm, kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm ( nangaphantsi kwe-0.2mm), kwaye ukuchaneka komgangatho wokuqengqeleka okubandayo kuphezulu kunoko kuqengqeleka okushushu.
Imbonakalo: Nangona ubukhulu bodonga lombhobho wentsimbi eqengqelekayo nengenamthungo buncinci ngokubanzi kunobo bombhobho wentsimbi eqengqelekayo eqengqelekayo, umphezulu ujongeka uqaqambile kunodonga olungqindilili oluqengqelekayo lombhobho wentsimbi engenamthungo, umphezulu awurhabaxa kakhulu, kwaye umphezulu womgangatho ubonakala uqaqambile. Idayamitha ayinazo iibhula ezininzi kakhulu.
Ubume bokuhanjiswa: Iibhobho zetsimbi ezishushu ezishushu zihanjiswa kwindawo eshushu okanye ephethwe ngubushushu, kwaye iipayipi zentsimbi ezipholileyo zihanjiswa kwimeko yokushisa.
