Kev tsim cov kub dov seamless raj perforation yog cov kauj ruam tseem ceeb tshaj plaws ntawm deformation, nws lub hom phiaj yog hnav ib lub raj khoom dov rau hauv lub raj hollow. Raws li cov qauv thiab cov yam ntxwv deformation tho txheej txheem ntawm lub tshuab tho tuaj yeem muab faib ua cov qauv perforating: oblique tho, tho lub thawb thiab siab perforation, tho thiab oblique feem ntau siv, cov duab ntawm lub tshuab tho lub tshuab yob muaj yob, kab mob mis ( cone) thiab disc yog peb hom piercing zeb dov zeb yob rau siv me me, thaum loj units siv cov kab mob hom piercer rolls. Disc punch tsis tshua siv. Tsis hais txog cov yob puab ua li cas, thiaj li ua kom lub raj raj tom thiab cov pob tshab cones), yob cov kab txuas ntawm lub khob hliav qab (yob tawm cov kab txuas ( nruab nrab) kev sib xyaw.

Piercer yob siv kev sib xyaw ua ke ntawm cov menyuam thiab cov qauv ntawm cov menyuam lub tes tsho, ob qho tib si ntawm kev cuam tshuam ncaj qha lossis kev cuam tshuam ntawm kev cuam tshuam ntxiv rau qhov tseem ceeb ua ke. Yog li, thaum lub yob seem, cov yob tuaj yeem rov siv dua, txhawm rau txo cov nqi siv. Me me punch rau cov khoom siv ntau dua ntawm 45 lossis 40Cr, quenched thiab tempered. Loj punch rollers ntau 42CrMo, quenching thiab tempering. Yob cov khoom lag luam tam sim no siv ntau txoj hauv kev, qee cov tuam txhab siv 45, 55 thiab lwm yam forging zoo carbon structural steel. Qee lub tuam txhab siv 50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo alloy cam khwb cia lossis forged; Cov kev xav tau ntawm hardness ntau yam tsis sib xws, thiab qee qhov xav tau HB180-220, qee qhov xav tau HB220-260. Txhawm rau kom nce qhov tom ntawm cov loj perforated cov menyuam ua qhov tob ntawm 0.8 ~ 1.2m mesh qauv ntawm lub inlet lub khob hliav qab.

Cov tuam txhab tsim khoom hauv tsev thiab txawv teb chaws xaiv cov khoom siv thiab kev siv, Kuv xav tias: qhov kev xaiv ntawm casting yob punch 50Mn, 60CrMnMo carbon steel thiab lwm yam ntaub ntawv tsim nyog, ib qho muaj zog zoo thiab hnav tsis kam, qhov thib ob yog siv rau txhua hom khoom siv yeeb nkab. . Hardness Control nyob rau hauv HB200-240 ntau tsim nyog.
