8 Cov txheej txheem loj Tube Rolling

• Ehrhardt dov txheej txheem

Ehrhardt nyob rau xyoo 1891 tau tsim cov txheej txheem hydraulic xuas nrig ntaus los tsim cov punched khob billet, thiab ua tiav xyoo 1899 nrog lub mandrel yuav raug punched billet thawb los ntawm ntau txoj kab uas hla maj mam txo lub nplhaib los tsim seamless steel yeeb nkab txoj kev. Feem ntau kuj hu ua yeeb nkab jacking txheej txheem.

Niaj hnub no, cov kav hlau tsis muaj seamless loj tseem yog tsim los ntawm cov yeeb nkab jacking txoj kev, nrog qhov siab tshaj plaws txoj kab uas hla mus txog 1,066 hli. Nyob rau xyoo 1980, Mannesmann tau tsim cov txheej txheem no rau hauv cov txheej txheem CPE, uas feem ntau tsim me me thiab nruab nrab - txoj kab uas hla seamless steel

• tsis siv neeg dov txheej txheem

Stiefel (Stiefel) hauv xyoo 1895 tom qab tau txais daim ntawv pov thawj ntawm lub disk- hom tho tshuab, thawj lub tshuab dov tsis siv neeg hauv xyoo 1903 hauv Tebchaws Meskas tau mus ua haujlwm hauv xyoo 1905, kev siv txawm tias lub tshuab tau yug los hauv 1905, lub tshuab dov tsis siv neeg. Tsis siv neeg raj zeb tseem hu ua Stiefel dov zeb. Tom qab ntawd, tsis siv neeg dov zeb ib zaug dhau los ua cov khoom tseem ceeb ntawm seamless steel yeeb nkab chav tsev.

• Diesel dov txheej txheem thiab Accu Rolling txheej txheem

Sam Diescher thawj lub tswv yim qhia txog kev taw qhia ntawm kev sib hloov daim ntawv qhia ob- yob inclined zeb es tsis txhob ntawm daim ntawv qhia thawj, txhawm rau txuas ntxiv cov dov ntawm cov kav dej, thiab xyoo 1932 yug thawj Diesel (Diescher) dov zeb. Ib nrab xyoo tom qab, US AS tuam txhab thawj zaug qhia conical yob rau hauv inclined raj zeb thiab patented, nyob rau hauv 1989 lub ntiaj teb no thawj Accu Roll raj zeb nyob rau hauv Yantai, Tuam Tshoj, rau hauv ntau lawm.

• peb -rolling txheej txheem

Qhov no yog peb - yob tilt dov txheej txheem, lub raj hauv mandrel thiab peb yob yog dov ntawm qhov txuas ntxiv ntawm peb - yob zeb, los yog Assel (Assel) zeb.

• kub extrusion raj txheej txheem

Thaum ntxov raws li qhov kev tsim ntawm Mannesmann cov kwv tij oblique dov perforation ua ntej, tau muaj kev siv kub extrusion ntawm txhuas txheej txheem los tsim seamless steel raj patents. Txawm li cas los xij, nws tsuas yog tom qab kev nthuav qhia ua tiav ntawm cov iav lubricants hauv xyoo 1950 tias cov txheej txheem kub extrusion rau cov hlab steel tau txais daim ntawv thov tiag tiag thiab kev loj hlob sai. Cov txheej txheem kub extrusion niaj hnub no feem ntau yog siv rau kev tsim cov siab - alloyed nyuaj- rau -deform hlab thiab cov raj profiled.

• txuas ntxiv dov txheej txheem

Thaum ntxov li 1891 nyob rau hauv lub tebchaws United States Kellogg (Kellogg) steel yeeb nkab Hoobkas tau txais patent rau nruam dov zeb. Txawm li cas los xij, vim muaj ntau qhov laj thawj, cov txheej txheem no tsis tau ua tiav tiag tiag. Txog thaum xyoo 1950s cov txheej txheem no tau muaj kev loj hlob loj, thiab nrog nws lub peev xwm siab, kev ua haujlwm siab, zoo siab thiab maj mam ua cov khoom siv seamless steel yeeb nkab ua zeb.

Thoob plaws hauv ntau yam txheej txheem dov saum toj no, lawv tau yug los nyob rau lub sijhawm sib txawv, tom qab kev txhim kho txuas ntxiv thiab kev txhim kho ntawm lawv tus kheej cov yam ntxwv kom tau raws li kev lag luam specifications, ntau yam ntawm cov khoom, zoo thiab txawv batch loj yuav tsum tau. Thiab nyob rau lub sijhawm sib txawv, kev tsim ua tiav ntawm ntau yam seamless steel yeeb nkab ntau lawm. Tam sim no peb - yob planetary raj zeb (PSW) thiab tho tshuab dov txheej txheem (CPS) kev txhim kho thiab kev loj hlob, qhia tias lub ntiaj teb no tseem tshawb nrhiav cov txheej txheem dov tshiab.

• txias kos duab (rolling) yeeb nkab txheej txheem

Txhawm rau nthuav dav, ntxiv thiab txhim kho ntau yam thiab zoo ntawm cov kub - dov seamless steel yeeb nkab, cov txheej txheem ua haujlwm thib ob siv hauv cov yeeb nkab - txias rub (dov) thiab cov txheej txheem kub kub nthuav dav tau tsim raws li.

Raws li thaum ntxov nyob rau hauv lub kub - dov seamless steel yeeb nkab ntau lawm txoj kev siv ua ntej lub txias txheej txheem tau siv nyob rau hauv lub thib ob ua ntawm welded kav. Cov txheej txheem txias dov yog patented los ntawm US Tabl Reduing tuam txhab nyob rau hauv 1931, siv tib lub voj voog ntawm cov yeeb nkab zeb deformation txheej txheem (rack reciprocating motion, multi-channel deformation), thiaj li hu ua txias Pilger zeb.

Kev kos duab txias (dov) txoj kev tuaj yeem tsis tsuas yog ua kom kub dov txoj kev nyuaj rau tsim (lossis tsis tsim nyog) lossis tsis tuaj yeem tsim cov khoom tshwj xeeb ntawm ntau yam thiab siab -cov kev xav tau zoo ntawm cov khoom, tab sis kuj tuaj yeem siv los hnav dov billet es tsis txhob kub- dov ntau lawm ntawm me me - cov raj loj thiab siab - zoo li steel tube, thiab lwm yam. Tam sim no, Tuam Tshoj cov khoom txias rub tawm (dov) suav txog li 20% ntawm tag nrho cov khoom siv seamless steel yeeb nkab, ntau dua li Tebchaws Meskas, Nyiv, thiab lwm lub tebchaws.
