Kugadzirwa kwekupisa-yakakungurutswa isina musono chubhu perforation ndiyo nhanho yakakosha ye deformation, basa rayo ndere kupfeka chubhu yakasimba yakakungurutswa mugomba chubhu. Zvinoenderana nechimiro uye deformation maitiro ekuboora muchina wekuboora anogona kukamurwa kuita yakajairwa perforating nzira: kuboora oblique, kubaya kusunda uye kumanikidza perforation, kuboora uye oblique inonyanya kushandiswa, chimiro cheinotenderera yekuboora muchina mipumburu ine roll, mabhakitiriya formula. cone) uye dhisiki mhando nhatu dzinobaya chigayo rolling mill rolls kuti ishandiswe mudiki, nepo mahombe mayuniti anoshandisa mabhakitiriya emhando yekubaya rolls. Disc punch haiwanzo shandiswa. Zvisinei nechimiro chemupumburu sei, kuitira kuti ive nechokwadi chekuti chubhu inoruma uye kuita kubaya maitiro ane perforated cone (roll inlet cone), kugaya mill cone (roll outlet cone) uye rolled strip (yakawandisa chikamu cheiyo inlet cone uye yekubuda koni. pakati )kuumbwa.

Piercer roll inoshandisa musanganiswa wemarollers uye chimiro cheroller sleeve, zvese zvekukanganisa zvakananga kana musanganiswa wekukanganisa pamwe nekiyi musanganiswa. Nekudaro, kana iyo roll scrap, rollers inogona kuramba ichishandisa zvakare, kuderedza mutengo wekushandisa. Diki punch roller zvinhu sarudzo yakawanda ye45 kana 40Cr, yakadzimwa uye yakatsamwa. Mahombe punch rollers akawanda 42CrMo, kudzima uye kupisa. Vagadziri vezvigadzirwa parizvino vari kushandisa zvakanyanya kuomarara, vamwe vagadziri vanoshandisa makumi mana neshanu, makumi mashanu neshanu uye zvichingodaro kugadzira emhando yepamusoro kabhoni structural simbi. Vamwe vanogadzira vanoshandisa 50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo alloy cast kana kufoja; kuomarara kwemhando zvinodiwa hazvienderane, uye zvimwe zvinoda HB180-220, zvimwe zvinoda HB220-260. Kuti uwedzere kuruma kweiyo hombe perforated roller general processing kudzika kwe 0.8 ~ 1.2mm mesh patani ye inlet cone.

Vagadziri vemukati uye vekunze vanogadzira zvinhu zvekusarudza uye kushandiswa, ndinofunga: sarudzo yekukanda punch punch 50Mn, 60CrMnMo kabhoni simbi uye zvimwe zvinhu zvakanyanya kufanira, imwe ine simba rakanaka uye kupfeka kuramba, yechipiri inoshandiswa kune imwe neimwe inotenderera mhando dzepombi. . Kuomeswa Kudzora muHB200-240 zvakanyanya kunzwisisika.
