Ukuveliswa kwetyhubhu engenamthungo eshushu-eqengqelekayo lelona nyathelo libalulekileyo lokuguqulwa, injongo yalo kukunxiba ityhubhu eqinileyo eqengqeleke kwityhubhu engenanto.Ngokwesakhiwo kunye neempawu ze-deformation inkqubo yokugqobhoza yomatshini wokugqobhoza inokwahlulwa ibe yindlela eqhelekileyo yokugqobhoza: ukugqobhoza oblique, ukugqobhoza ukutyhala kunye noxinzelelo lokugqobhoza, ukugqobhoza kunye ne-oblique esetyenziswa kakhulu, imilo yomatshini wokugqobhoza i-rotary roll, ibhaktheriya ifomula ( cone) kunye nediski luhlobo oluthathu lokugqobhoza imiqulu yokusila ukuze isetyenziswe kwincinci, ngelixa iiyunithi ezinkulu zisebenzisa iibhaktheriya zohlobo lokugqobhoza imiqulu.I-disc punch ayifane isetyenziswe.Kungakhathaliseki ukuba imilo umqulu njani, ukuze kuqinisekiswe ukulunywa ityhubhu kwaye kuphunyezwe inkqubo yokugqobhoza inecone enemingxuma (roll inlet cone), lokusila cone (roll outlet cone) kunye roll rolling strip (inxalenye egqithisileyo yecone yokungena kunye necone yokuphuma phakathi )nokwakheka.

I-Piercer roll isebenzisa indibaniselwano ye-roller kunye nesakhiwo somkhono we-roller, zombini ukuphazamiseka ngokuthe ngqo okanye indibaniselwano yokuphazamiseka kunye nokudibanisa okubalulekileyo.Ngaloo ndlela, xa i-roll scrap, i-rollers ingaqhubeka nokusebenzisa kwakhona, ukunciphisa iindleko zezixhobo.Izinto ezincinci ze-punch roller ukhetho olungakumbi lwe-45 okanye i-40Cr, lucinywe kwaye lunomsindo.Ii-roller ezinkulu ze-punch ezininzi ze-42CrMo, ezicimayo kunye nokufudumala.Abavelisi bezinto eziqengqelekayo ngoku abasebenzisa intsonkothe ​​ngakumbi, abanye abavelisi basebenzisa i-45, i-55 njalo njalo ngokwenza insimbi ephezulu ye-carbon structural.Abanye abavelisi basebenzisa i-50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo i-alloy cast okanye i-forged;Iimfuno zoluhlu lobunzima azihambelani, kwaye ezinye zifuna i-HB180-220, ezinye zifuna i-HB220-260.Ukuze kwandiswe ukulunywa kwerola enkulu enemingxuma kubunzulu bokucubungula jikelele obuyi-0.8 ~ 1.2mm yepateni yemesh yecone yokungena.

Abavelisi ababanzi basekhaya nabangaphandle bokukhethwa kwezinto kunye nokusetyenziswa, ndicinga ukuba: ukhetho lokuphosa umqulu we-punch 50Mn, i-60CrMnMo carbon steel kunye nezinye izinto ezifanelekileyo, omnye unamandla amahle kunye nokumelana nokunxiba, okwesibini kusetyenziswe kwiintlobo zombhobho wezinto eziphathekayo. .Ukulawulwa koBulukhuni kwi-HB200-240 kunengqiqo ngakumbi.
