Ukukhiqizwa kokubhobozwa kweshubhu elingenamthungo eligoqiwe ngokushisayo kuyisinyathelo esibaluleke kakhulu sokuguga, umgomo wako ukugqoka ishubhu eliqinile eligingqe libe yishubhu elingenalutho. Ngokusho kwesakhiwo kanye nezici zokuguqulwa kwenqubo yokubhoboza yomshini wokubhoboza ingahlukaniswa ngendlela evamile yokubhoboza: ukubhoboza i-oblique, ukubhoboza ukubhoboza kanye nokubhoboza ingcindezi, ukubhoboza kanye ne-oblique esetshenziswa kakhulu, ukwakheka kwemiqulu yomshini wokubhoboza okujikelezayo kunomqulu, ifomula yamagciwane ( cone) kanye nediski izinhlobo ezintathu zokubhoboza izigayo ezigaywayo ukuze zisetshenziswe ezincane, kuyilapho amayunithi amakhulu asebenzisa amaroli okubhoboza ohlobo lwebhaktheriya. I-disc punch ayivamile ukusetshenziswa. Kungakhathaliseki ukuthi umumo womqulu unjani, ukuze kuqinisekiswe ukuthi ukuluma kweshubhu futhi kuzuzwe inqubo yokubhoboza kune-cone enezimbobo (i-roll inlet cone), i-gay cone (i-roll outlet cone) kanye nomugqa ogoqiwe (ingxenye eyeqile ye-inlet cone kanye ne-outlet cone. phakathi )ukwakheka.

I-Piercer roll isebenzisa inhlanganisela yamarola nesakhiwo somkhono werola, kokubili ukuphazamiseka okuqondile noma inhlanganisela yokuphazamiseka kanye nenhlanganisela yokhiye. Ngakho-ke, lapho i-roll scrap, ama-rollers angaqhubeka nokusebenzisa kabusha, ukunciphisa izindleko zamathuluzi. Impahla ye-punch roller encane ukukhetha okwengeziwe kwe-45 noma 40Cr, kucishiwe futhi kuthulile. Ama-punch roller amakhulu ama-multi 42CrMo, acishayo futhi ayashisa. Abakhiqizi bezinto zokugoqa okwamanje abasebenzisa inkimbinkimbi, abanye abakhiqizi basebenzisa i-45, 55 njalonjalo bakha insimbi yekhwalithi ephezulu ye-carbon structural. Abanye abakhiqizi basebenzisa ingxubevange engu-50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo noma i-alloy cast; izimfuneko zobubanzi bokuqina azihambisani, futhi ezinye zidinga i-HB180-220, ezinye zidinga i-HB220-260. Ukuze kwandiswe ukulunywa kwerola elikhulu elinembobo elijwayelekile lokucubungula ukujula kwephethini yemeshi engu-0.8 ~ 1.2mm yekhoni yokungena.

Abakhiqizi abaphelele basekhaya nabangaphandle bokukhethwa nokusetshenziswa kwezinto ezibonakalayo, ngicabanga: ukukhetha kwe-casting roll punch 50Mn, 60CrMnMo carbon steel nezinye izinto ezifanele kakhulu, unamandla amahle nokumelana nokugqoka, okwesibili kusetshenziselwa izinhlobo zepayipi lezinto ezibonakalayo. . Ukulawula Ukuqina ku-HB200-240 kunengqondo kakhudlwana.
