Imibhobho Inkangeleko: ubungakanani. Imibhobho profile Steel

Profile zobukhulu tube leyo kunxibelelana GOST imele eyongeziweyo lobeko lwe ngentsimbi tubular. Iimveliso ezinjalo ifomu non-esezantsi, ngokubhekisele emnqamlezweni-candelo. Xa kuthelekiswa amanqaku ngeenxa zonke, icandelo umnqamlezo ityhubhu ezimile anokuba seqanda, isikwere, uxande okanye uxande elintlangothi ajikelezayo.

Ububanzi bokusebenzisa

tube profiled, imilinganiselo apho zinokwahluka, ayenzelwanga ukuba umbhobho ngokubekwa, kodwa ifreyim yesinyithi. tube Ulenze unalo ngumkhinkqi enye intonga bonke-metal, esiyinyaniso kwimeko apho Ubukhulu wemveliso alingana imilinganiselo ceca yabucala-metal. Xa wayeza kuba-40% ngaphantsi xa kuthelekiswa nawo onke-metal omnye lo ubunzima bomzimba vuphukuphuku. tube, ogama imilinganiselo kuvumela ukuphumeza zonke yoyilo kunokwenzeka, profiled kunciphisa iindleko kunye ubunzima izakhiwo yesinyithi, eshiya imilinganiselo ingatshintshanga namandla noshowo. Noko ke, le ugcino kwenzeka kuphela kwimeko xa kule khosi ngokwenziwa kweemveliso ezizodwa lilawulwa imilinganiselo.

Ukuxhomekeka pipe profile ubungakanani

tube profiled, ogama imilinganiselo zimiselwa parameters amathathu, kubandakanywa nobubanzi, ukuphakama kunye nodonga ubukhulu, ingenziwa ngokuthi indlela ethile. Kwimveliso mveliso, kukho inkqubo ezintathu zobugcisa ye mveliso i tubular ochazwe liqengqiwe phakathi kwabo: deformation kushushu, deformation ebandayo, nokwakha ngakumbi iprofayili kunye namalungu welding. Inkqubo kwezobugcisa kuchaphazela indlela yongqanianiso, Ebubanzini bodonga kunye nezinye nemilinganiselo kwimibhobho.

Ubungakanani kweemveliso hot-wasusa

ityhubhu ezimile, apho ubona i ifoto kweli nqaku, ungenza kwenziwa indlela ebandakanya eshushu-technology. Le nto itshiswe ukunyusa plasticity, oko ofumana imilo umkhono okanye emkhonweni. nosaziwayo umqolo asongwe ngokuya imveliso ibe setyhula icandelo tube ne inkangeleko ethile. Le mveliso semifinished ikhutshwa kwindawo kumatshini nkosana, eliveza ityhubhu ngeenxa ibe ebuxande, elimbhoxo okanye isikwere. Emva kokuba preform lupholisiwe, saliqengqa yi-roller. Ukuba, ngethuba imveliso square yabucala Umbhobho sele ifunyenwe, ifoto linikwa kwi nqaku, imilinganiselo candelo asinakukwazi ukuba milimitha ngaphantsi kwama-60. Ukuba sicinga amanqaku buxande igeyiji leyo zigqitywa GOST 8645-68, ngoko loo ubungakanani ziya kuba malunga 20. Inani elifanayo zobukhulu eliquka GOST 8639-82.

Owokugqibela le migangatho karhulumente uchaze imilinganiso yeemveliso profile square. Kuzo zombini ezi meko dimensions somhlathi ziyahluka ukusuka kuma-60 x 60 ukuya 230 x 100 iimilimitha. Noko ke, iityhubhu eshushu-ezityikitywe nge square profile cross-icandelo Enye mda imilinganiselo. Kule meko ke isikwere zinamacala 180 mm. Ukuba swiyenge umbhobho buxande yaveliswa ngu deformation eshushu, ithuba elilandelayo, iphenjelelwa iteknoloji - lo Ebubanzini bodonga. Ngoko ityhubhu inokuba isikwere okanye buxande, wathi kufuneka ungabi ngaphantsi kwe eemilimitha 4 parameter. Ngokumalunga Ebubanzini ubuninzi GOST 8639-82, ukuba ngemilimitha-14.

ubude tube emise

amacandelo Pipe ziyinxalenye yebala mazimile buxande kunokuba ubude ezahlukeneyo. Ngapha koko, eli nani kuba umlinganiselo ukuba unika ukulingana obude ethile, okanye off-yobu-, nto leyo equka ngokufumana imida ingxenye. Kwaye akunamsebenzi ukuba ifomu iya kuba ubukhulu imveliso yokugqibela iimveliso kule akayi kutshintsha. Ubude ubuncinane elilingana-4 m, kanti kwexabiso eliphezulu kweemitha 12.5.

Imilinganiso yemibhobho abandayo-wasusa

Steel yabucala pipe nga kuveliswa yi deformation ebandayo kunye nobugcisa. Ngenxa yoko, kunokwenzeka ukuba afumane imveliso leyo has a iimpawu ezifihlakeleyo ngakumbi xa kuthelekiswa nalowo eshushu. The main iimpawu leyo iza kucacisa iimpawu imveliso, oku cross-candelo imilinganiselo kunye nodonga ubukhulu. Ubukhulu somhlathi iindwendwe ayikwazi ibe ngaphantsi kwe-10 eemilimitha. Ubukhulu inkulu ngohlangothi ayidluli 120 iimilimitha. Ngenxa yoko, tube kuhlinzwa profiled ezibandayo liqengqiwe, asinakuba inkangeleko yakhe bungu ezincinane kwe 10x10 eemilimitha. Ubukhulu inkulu kwicandelo zomnqamlezo umbhobho enjalo 120x120 iimilimitha. Phantsi kwale umgangatho bamba ubukhulu 17, ziphantsi GOST 8639-82 kunye, kwakunye-16 ubukhulu standard, ezinxulumene GOST 8645-68.

Ingqele liqengqiwe profile umbhobho kwalenza uba Ebubanzini bodonga-1 ezinga- ukuya ngemilimitha-8. Ukukhethwa iimveliso ezifana bugwetyelwe ukuba, xa kukho imfuneko imveliso leyo akanalo yaseZimbabwe, kwaye neendonga ezibhityileyo. Ubude yemibhobho ezinjalo, ezithi zenziwe ngohlobo amacandelo ezincinane, iyahluka ukusuka cm-4 ukuya kowe-11 5. A ubude imveliso abandayo-liqengqiwe yenziwe ngohlobo ziqwempu hayi-mbini, iyahluka ukusuka komgomo we 1.5m ukuya ku-9.

Amacala imibhobho yabucala nge welding

Amacandelo pipe unako kwalenza omthuqwa. Ngelo kwinqanaba lokuqala iimakhishithi preform mbini, nto leyo siyahlukana sheet ngentsimbi le. Ngaphezu koko ukusuka izinto ezingenanto akhiwa kruthu kwaye emva kokuba iwelding ingenamthungo luyenziwa. Le nkqubo isebenzisa i egalelwe igesi okanye induction yokunyibilikisa. Isiphumo inkangeleko tube, ixabiso eza zicaciswe apha ngezantsi. iipropati ebonakalayo musa yahluke yeempawu eriyeli iimveliso. kwizinga eliphezulu komphetho uyakwazi Ukukhulula ngumkhinkqi lemveliso nge% 10 kuphela. ukuqina okwehlileyo kwenza kube lula ukwenza imveliso yayo kweendonga abe ubukhulu ku ezahlukene milimitha-1 ukuya ku-5. Imilinganiselo Kanjalo zisukela milimitha 10x10 ukuya 100x100.

Ubude umbhobho yabucala nge welding

ityhubhu ezimile 40 * 40, kwakunye nemveliso nge cross-icandelo ezohlukeneyo ubude ntathu kunye ngokomthamo. Kwimeko yokuqala ubude iyafakwa kuluhlu ukusuka kwiimitha ezi-5 ukuya ku-9. Kule yesibini - inani ziyahluka ukusuka komgomo we 1.5m ukuya ku-9.

Kwimibhobho okweqanda kunye okweqanda cross-icandelo

Ukongeza inxaki kwaye iimveliso buxande, ngenxa weld imveliso ungenza ithumbu elimbhoxo. imilinganiso zawo ezimiselwe GOST 8642-68. Ngokutsho kolu xwebhu, ngokorhwebo imibhobho ezikhoyo zingabonakala, imilinganiso apho ziyahluka ukusuka 16h10 ukuya 90h32 nawethu. Udonga zenza amanqaku anjalo mm hayi ngaphezulu kwe 2.5 ngokubhekisele ixabiso elincinane, nto ilingana no-1 nawethu.

yakha iindleko tube kwecandelo square

Ukuba unomdla ityhubhu profiled, ixabiso le mveliso kufuneka ube nomdla. Kuba imitha enye nelembande, icandelo square kunye ecaleni kwe-15 mm kuya kufuneka ukuba uhlawule 94 engange. Weight 1 imitha kule meko 0.57 kg. Ukuba icandelo encomekayo ngakumbi 20x20, kuba kuya kufuneka ukuba uhlawule 147 engange / imitha. Ebubanzini bodonga iya kuba 1.5 mm, ubunzima imitha nganye elilingana 0.95 kg. 40 * profiled tube-40, kunye Ebubanzini bodonga 1.5 mm engange-296 ngemitha nganye. Ngokwandisa kodonga ukuya ixabiso 2 eemilimitha lisingisa 377 engange. Enye imitha ubunzima kwi-2, kilograms 6. Oku kubaluleke xa odola izithuthi.

Imibhobho Iprofayili olubuxande kwicala 60x40 ezixabisa 344 engange imitha nganye, eliya kusebenza udonga ububanzi 1, 5 mm. Ukunyuka parameter wokugqibela milimitha 2 kwandisa iindleko ukuya ku 493 engange. isikwere 100 x 100 Iindleko imveliso 1377 engange imitha nganye. Udonga zenza ngemilimitha-3. Okoxande tube 100x50 kunye ludonga 3 eemilimitha ezixabisa 1007 engange imitha nganye. Ungakhetha ngokwabo imveliso, imilinganiso apho kunxibelelana iinjongo. Ifumaneka amelwe a iityhubhu ezininzi omkhulu profiled amacandelo aye ubude ezahlukeneyo, kunye nende nodonga.

Imfuneko ukulawula ubungakanani kwemibhobho profile

Abathengi badla uyazibuza ukuba kutheni Ubukhulu kubaluleke kangaka iimveliso profile, leyo enziwa ngokwemigaqo karhulumente. Impendulo yalo mbuzo ngumzekelo yokusetyenziswa - loo iityhubhu zisetyenziswa lezakhelo bangenzelwa, kangangokuba unxaxho kancinane imilinganiselo candelo emnqamlezweni uyakwazi kulwenze yokugqibela intsimbi. Products, zebanga yeyiphi ezingahambelaniyo nemigangatho karhulumente, ingabizwa yingozi ngenxa yokuba ukusetyenziswa kwazo kunokukhokelela neziphumo ezibi ukuba uhlobo lomonakalo kwisakhiwo yonke.
