Muaj rau txoj kev ua haujlwm tseem ceeb rau cov kav dej seamless (SMLS):
1. Txoj kev forging: Siv lub tshuab swage forging los ncab qhov kawg lossis ib feem ntawm cov yeeb nkab kom txo tau cov kab uas hla.Feem ntau siv swage forging tshuab muaj xws li hom teb, txuas hom pas nrig, thiab hom rau cov menyuam.
2. Stamping txoj kev: Siv ib tug tapered core ntawm lub tshuab xuas nrig ntaus kom nthuav lub raj kawg mus rau qhov yuav tsum tau muaj qhov loj thiab cov duab.
3. Cov txheej txheem ntawm cov menyuam: muab cov tub ntxhais tso rau hauv lub raj, thiab thawb lub voj voog sab nraud nrog cov menyuam rau kev ua haujlwm ntawm ntug.
4. Rolling txoj kev: Feem ntau, tsis muaj mandrel yuav tsum tau, thiab nws yog haum rau lub puab puag ncig ntug ntawm tuab-walled hlab.
5. Txoj kev khoov: Muaj peb txoj kev siv ntau, ib txoj kev hu ua txoj kev nthuav dav, lwm txoj kev hu ua stamping method, thiab txoj kev thib peb yog txoj kev rau cov menyuam.Muaj 3-4 rollers, ob taag rollers, thiab ib qho kev hloov kho cov menyuam.Nrog ib tug ruaj yob suab, cov yeeb nkab tiav yog tortuous.
6. Txoj kev bulging: Ib qho yog muab cov roj hmab tso rau hauv cov yeeb nkab, thiab siv cov punch kom nruj rau sab saum toj kom cov yeeb nkab protrude;Lwm txoj kev yog hydraulic bulging, sau nruab nrab ntawm cov yeeb nkab nrog kua, thiab cov kua siab bulges cov yeeb nkab rau hauv cov duab xav tau.Feem ntau ntawm cov duab thiab tso tawm ntawm cov kav dej corrugated yog txoj hauv kev zoo tshaj plaws.
Raws li qhov sib txawv ntawm kev ua haujlwm kub ntawm seamless steel kav, seamless steel kav muab faib ua haujlwm txias thiab kub ua haujlwm.
Kub dov seamless steel yeeb nkab: ua kom sov lub raj xa dej mus rau qhov kub thiab txias ua ntej, tom qab ntawd perforate nws, ces mus rau nruam dov los yog extrusion, ces mus rau stripping thiab sizing, ces txias mus rau lub billet raj thiab straightening, thiab thaum kawg Nws yog los ua cov txheej txheem xws li kev sim kuaj pom qhov tsis zoo, kos npe, thiab chaw khaws khoom.
Cold-drawn seamless steel yeeb nkab: cua sov, tho, taub hau, annealing, pickling, oiling, txias dov, billet raj, kho cua sov, straightening, flaw detection thiab lwm yam txheej txheem rau lub round raj billet.
