Iecaianoaaiiuo o wela-owili seamless tube perforation ka mea nui loa kaʻina o ka deformation, kona mission mea e komo i ka paʻa paipu i'ōwiliʻia i loko o ka hollow paipu.E like me ke ʻano a me nā ʻano deformation, hiki ke hoʻokaʻawale ʻia ke kaʻina hana o ka mīkini piercing i ke ʻano perforating maʻamau: oblique piercing, piercing push and pressure perforation, piercing a oblique i hoʻohana nui ʻia, ʻo ke ʻano o ka rotary piercing machine rolls he roll, bacteria formula ( cone) a me ka disc he ʻekolu ʻano piercing mill rolling mill rolling no ka hoʻohana ʻana i ka liʻiliʻi, aʻo nā ʻāpana nui e hoʻohana ana i nā ʻōwili piercer type bacteria.ʻAʻole hoʻohana ʻia ka punch disc.Me ka nānā 'ole o ke 'ano o ka'ōwili pehea, i mea e hō'oia ai i ka nahu o ka paipu a ho'okō i ke ka'ina o ka hou 'ana, ua perforated cone (roll inlet cone), wili wili cone (roll out cone) a me roll rolled strip (excessive part of the inlet cone and the outlet cone. ma waena ) hoʻohuihui.

Hoʻohana ʻo Piercer roll i ka hui ʻana o nā wili a me ke ʻano o ka lima o ka huila, ʻelua o ke keakea pololei a i ʻole ka hui pū ʻana o ka hoʻopili ʻana me ka hui kī.No laila, i ka wā e ʻoki ai ka ʻōwili, hiki ke hoʻomau i ka hoʻohana hou ʻana i nā wili, e hōʻemi i nā kumukūʻai mea hana.ʻOi aku ka nui o ka koho o 45 a i ʻole 40Cr, kinai ʻia a huhū.ʻO nā huila punch nui he 42CrMo, hoʻopiʻi a hoʻonā.Ke hoʻohana nei nā mea hana ʻōwili i nā mea paʻakikī i kēia manawa, hoʻohana kekahi mau mea hana i ka 45, 55 a pēlā aku e hana ana i ke kila kalapona kiʻekiʻe.Hoʻohana kekahi mau mea hana i ka 50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo i hoʻolei ʻia a hoʻopaʻa ʻia;ʻAʻole kūlike nā koi o ka laulā paʻakikī, a koi kekahi i HB180-220, koi kekahi i HB220-260.I mea e hoʻonui ai i ka nahu o ka nui perforated roller ka hohonu hoʻoponopono maʻamau o 0.8 ~ 1.2mm mesh kumu o ka cone inlet.

ʻO nā mea hana hale a me nā ʻāina ʻē aʻe o ke koho ʻana a me ka hoʻohana ʻana, manaʻo wau: ʻo ke koho ʻana o ka hoʻolei ʻana i ka roll punch 50Mn, 60CrMnMo carbon steel a me nā mea ʻē aʻe i kūpono, ʻoi aku ka ikaika a me ke kūpaʻa ʻana o kekahi, ua hoʻopili ʻia ka lua i kēlā me kēia ʻano ʻano paipu. .Manaʻo paʻakikī ma HB200-240 kūpono.
