Blanking inzira yekutsika iyo inoshandisa difa kuparadzanisa mapepa kubva kune rimwe nerimwe.Kuvhara kunonyanya kureva kuvhara nekurova.Iyo punching kana process part inobaya chimiro chaidiwa kubva pabepa parutivi pekavharwa contour inonzi blanking, uye buri rinobaya chimiro chaunoda kubva muchikamu chechirongwa chinonzi punching.
Blanking ndeimwe yeanonyanya kukosha maitiro mukuita chitambi.Iyo haigone kungobaya zvakananga kunze kwezvikamu zvakapedzwa, asi zvakare kugadzirira ma blanks emamwe maitiro akadai sekukotama, kudhirowa kwakadzika uye kuumba, saka inoshandiswa zvakanyanya mukugadzirisa zvitambi.
Kuvhara kunogona kupatsanurwa muzvikamu zviviri: kusavhara zvakajairika uye kusavhara zvakanaka.Kuvhara kwakajairika kunoona kupatsanurwa kwemashiti nenzira yekucheka kwekucheka pakati pe convex uye concave inofa;kuvharika kwakanaka kunoona kupatsanurwa kwemashizha muchimiro chepurasitiki deformation.
Iyo blanking deformation process yakakamurwa kuita matanho matatu anotevera: 1. The elastic deformation stage;2. The epurasitiki deformation danho;3. The kuputsika kupatsanurwa danho.
Hunhu hwechikamu chisina chinhu chinoreva mamiriro emuchinjiko, kurongeka kwedimensional uye kukanganisa kwechimiro chechikamu chisina chinhu.Chikamu chechikamu chisina kuvhara chinofanira kunge chakamira uye chakatsetseka sezvinobvira nemabhuru madiki;kurongeka kwedimensional kunofanirwa kuvimbiswa kuve mukati meiyo kushivirira renji inotsanangurwa mukudhirowa;chimiro chechikamu chisina kuvharwa chinofanira kusangana nezvinodiwa zvekudhirowa, uye nzvimbo yacho inofanira kunge yakamira sezvinobvira.
Pane zvinhu zvakawanda zvinokanganisa kunaka kwezvikamu zvisina kuvharwa, kunyanya zvinosanganisira zvivakwa, gap size uye kufanana, kupinza kwemupendero, chimiro che mold uye dhizaini, kurongeka kwe mold, nezvimwe.
Chikamu chechikamu chisina chinhu chinoratidza pachena nzvimbo ina, dzinoti slump, smooth surface, rough surface uye burr.Kudzidzira kwakaratidza kuti kana mupendero wepunch usina kujeka, pachava nemabhuru akajeka pamucheto wepamusoro wechikamu chisina kuvhara;apo mupendero wemukadzi unofa wakagomara, pachava nemabhururu akajeka pamucheto wezasi wegomba rechikamu chekubaya.
Kurongeka kwedimensional kwechikamu chisina chinhu kunoreva musiyano pakati pehukuru chaihwo hwechikamu chisina chinhu uye saizi yekutanga.Musiyano muduku, unowedzera kururama.Pane zvinhu zviviri zvakakura zvinokanganisa kurongeka kwedimensional yezvikamu zvisina chinhu: 1. Mamiriro uye kugadzirwa kweiyo punching kufa;2. Kutsauka kwechikamu chisina kuvhara maererano nehukuru hwepunch kana kufa mushure mekunge punching yapera.
Iko kukanganisa kwechimiro chezvikamu zvisina chinhu kunoreva kukanganisa kwakadai sekupeta, kumonyoroka, uye deformation, uye zvinofurira zvinhu zvakaoma kunzwisisa.Iyo chaiyo yehupfumi inogona kuwanikwa neyakajairwa simbi inovhara zvikamu ndeye IT11 ~ IT14, uye yepamusoro-soro inogona chete kusvika IT8~IT10.
