Ukuphambuka kwimibhobho yentsimbi enobubanzi obukhulu kwimveliso: Ubukhulu obuqhelekileyo bobukhulu bombhobho wentsimbi: ububanzi bangaphandle: 114mm-1440mm ubukhulu bodonga: 4mm-30mm. Ubude: bungenziwa bubude obusisigxina okanye ubude obungaqinanga ngokweemfuno zabathengi. Imibhobho yentsimbi enobubanzi obukhulu isetyenziswa ngokubanzi kumacandelo ahlukeneyo amashishini afana neenqwelomoya, i-aerospace, amandla, i-electronics, iimoto, imboni yokukhanya, njl., kwaye yenye yeenkqubo ezibalulekileyo ze-welding.

Iindlela eziphambili zokucutshungulwa kweemibhobho zetsimbi ezinobubanzi obukhulu zi: Ukubumba insimbi: indlela yokucubungula uxinzelelo esebenzisa amandla abuyiselayo empembelelo yesando sokubumba okanye uxinzelelo lokushicilela ukutshintsha i-billet kwimilo kunye nobukhulu esiyifunayo. I-Extrusion: Yindlela yokucubungula apho intsimbi ibeka isinyithi kwi-cylinder extrusion evaliweyo, ifake uxinzelelo kwelinye icala, kwaye icinezele isinyithi ngaphandle komngxuma wokufa ochaziweyo ukuze ufumane imveliso egqityiweyo kunye nesimo esifanayo kunye nobukhulu. Isetyenziswa kakhulu ekuveliseni intsimbi yentsimbi engekhoyo. Ukuqengqeleka: Indlela yokucutshungulwa koxinzelelo apho i-billet yensimbi yentsimbi idlula i-gap (iimilo ezahlukahlukeneyo) zee-roller ezijikelezayo, kwaye i-cross-section yezinto eziphathekayo iyancitshiswa kwaye ubude bunyuswa ngenxa yokunyanzeliswa kwee-roller. Umzobo wensimbi: Yindlela yokucubungula eyenza i-billet yensimbi eqengqelekayo (iprofayili, ityhubhu, imveliso, njl.) Ngomngxuma wokufa ukunciphisa i-cross-section kunye nokwandisa ubude. Isetyenziswa kakhulu kulungiso olubandayo.

Imibhobho yentsimbi enobubanzi obukhulu igqityezelwa ngokucuthwa koxinzelelo kunye nokuqengqeleka ngokuqhubekayo kwezinto ezisisiseko ezingenanto ngaphandle kwamandrels. Phantsi kwesiseko sokuqinisekisa ukuba umbhobho wentsimbi ejikelezayo, umbhobho wentsimbi ejiyileyo ufudunyezwa ukuya kutsho kubushushu obuphezulu obungaphezulu kwama-950℃ xa bubonke kwaye emva koko uqengqeleke kwimibhobho yentsimbi engenamthungo yemigaqo eyahlukahlukeneyo ngokusebenzisa ilitye lokusila lokunciphisa uxinezeleko. Uxwebhu oluqhelekileyo lokuveliswa kwemibhobho yentsimbi enobubanzi obukhulu lubonisa ukuba ukutenxa kuvunyelwe ekwenziweni kwemibhobho yentsimbi enobubanzi obukhulu: Ubude bokuphambuka okuvumelekileyo: Ubude obuvumelekileyo bokutenxa kwintsimbi yentsimbi xa buhanjiswa ngobude obumiselweyo abuyi kudlula + 50mm. I-Curvature kunye nokuphela: Ukugoba ukugoba kweentsimbi zetsimbi ezichanekileyo akufanele kuchaphazele ukusetyenziswa okuqhelekileyo, kwaye i-curvature iyonke akufanele idlule i-40% yobude obupheleleyo bentsimbi yentsimbi; iziphelo zeentsimbi zentsimbi kufuneka zichetywe ngokuthe tye, kwaye ukuguqulwa kwendawo akufanele kuchaphazele ukusetyenziswa. Ubude: Imivalo yensimbi idla ngokuhanjiswa ngobude obusisigxina, kwaye ubude obuthile bokuhanjiswa kufuneka buboniswe kwisivumelwano; xa iintsimbi zetsimbi zihanjiswa kwiikhoyili, i-coil nganye kufuneka ibe yintsimbi yentsimbi, kwaye i-5% yeentsimbi kwi-batch nganye ivumelekile ukuba ibe neentsimbi ezimbini. Ubunzima bekhoyili kunye nedayamitha yekhoyili imiselwa ngothethwano phakathi kwamaqela onikezelo kunye nemfuno.

Iindlela zokwenza imibhobho yentsimbi enobubanzi obukhulu:
1. Indlela yokwandisa i-push push: Isixhobo sokwandisa i-push silula, sinexabiso eliphantsi, kulula ukusigcina, sinoqoqosho, kwaye sihlala ixesha elide, kwaye iinkcukacha zemveliso zinokutshintshwa ngokuguquguqukayo. Ukuba ufuna ukulungisa imibhobho yentsimbi enobubanzi obukhulu kunye nezinye iimveliso ezifanayo, kufuneka udibanise kuphela ezinye izixhobo. Ilungele ukuveliswa kwemibhobho yentsimbi ephakathi kunye nebhityileyo enobubanzi obukhulu, kwaye inokuvelisa imibhobho enodonga olungqingqwa olungagqithisi umthamo wesixhobo.
2. Indlela ye-extrusion eshushu: I-blank idinga umatshini ngaphambi kokuba i-extrusion. Xa i-extruding imibhobho enobubanzi obungaphantsi kwe-100mm, utyalo-mali lwezixhobo luncinci, inkunkuma yezinto eziphathekayo incinci, kwaye iteknoloji ikhulile. Nangona kunjalo, xa ububanzi bombhobho bukhula, indlela yokutshisa i-extrusion idinga i-tonnage enkulu kunye nezixhobo eziphezulu zamandla, kunye nenkqubo yokulawula ehambelana nayo kufuneka iphuculwe.
3. Indlela yokugqobhoza eshushu: Ukugqobhoza okushushu kukuqengqeleka ubukhulu becala longitudinal rolling extension kunye ne-oblique rolling extension. Ukuqengqeleka ulwandiso longitudinal ikakhulu ibandakanya umda mandrel okuqhubekayo rolling, limited mandrel okuqhubekayo rolling, ezintathu-roller limited mandrel okuqhubekayo rolling, kunye mandrel ezidadayo eqhubekayo rolling. Ezi ndlela zinemveliso ephezulu, ukusetyenziswa kwentsimbi ephantsi, iimveliso ezilungileyo, kunye neenkqubo zokulawula, kwaye zisetyenziswa ngokubanzi.

Iiparamitha ezifanelekileyo zokufumana isiphene kwimibhobho yentsimbi enobubanzi obukhulu:
Ekuvelisweni kweemibhobho zetsimbi ezinobubanzi obukhulu, ukubandakanywa kwesetyhula enye kunye ne-pores kunye ne-weld diameter engadluli kwi-3.0mm okanye i-T / 3 (T yi-thickness echaziweyo yodonga lombhobho wensimbi) ifanelekile, nayiphi na into encinci. Kuyo nayiphi na i-150mm okanye i-12T ubude boluhlu lwe-weld (nokuba yeyiphi encinci), xa isithuba phakathi kokubandakanywa okukodwa kunye nepore ingaphantsi kwe-4T, isixa sedayamitha sazo zonke iziphene ezikhankanywe apha ngasentla ezivunyelwe ukuba zibekho ngokwahlukeneyo akufunekanga zidlule kwi-6.0mm. okanye 0.5T (nokuba yeyiphi encinci). Ukubandakanywa komcu omnye kunye nobude obungadlulanga kwi-12.0mm okanye i-T (nangona incinci) kunye nobubanzi obungadlulanga kwi-1.5mm bufanelekile. Ngaphakathi kwayo nayiphi na i-150mm okanye i-12T ubude be-weld (nokuba yeyiphi na encinci), xa isithuba phakathi kokufakwa komntu ngamnye singaphantsi kwe-4T, ubude obuphezulu be-cumulative bazo zonke iziphene ezikhankanywe ngasentla ezivunyelwe ukuba zibekho ngokwahlukeneyo akumele zidlule kwi-12.0mm. Umphetho wokuluma omnye wabo nabuphi na ubude obunobunzulu obuyi-0.4mm ufanelekile. Umphetho wokuluma okukodwa kunye nobude obuphezulu be-T/2, ubunzulu obuphezulu be-0.5mm kwaye ungadluli kwi-10% yobukhulu bodonga oluchaziweyo lufanelekile ukuba akukho mida yokuluma ngaphezu kwembini ngaphakathi kwayo nayiphi na i-300mm ubude be-weld. Yonke loo mida yokuluma kufuneka icolwe. Naluphi na umgca wokuluma ogqithise uluhlu olungentla lufanele lulungiswe, indawo eneengxaki kufuneka inqunyulwe, okanye yonke ipayipi yensimbi kufuneka inqatshelwe. Ukulunywa nabuphi na ubude kunye nobunzulu obudlulayo kwelinye icala le-weld yangaphakathi kunye ne-weld yangaphandle kwi-longitudinal direction ayifanelekanga.
