Txog kev kos duab tuag siv los ntawm cov punches sib txawv
Ib qho kev txiav txim punch kos duab tuag
Tensile tuag rau ib qho punch yog hais txog lub tensile tuag siv hauv eccentric los yog crankshaft punch nrog tsuas yog ib qho swb. Muaj ntau hom kev kos duab tuag raws li tus txheej txheem.
4. Rov qab kos duab tuag
Rov qab kos duab tuag yog hais txog kev kos duab tuag nyob rau hauv uas cov punch raug thawb los ntawm hauv qab ntawm qhov khoob hauv qhov thim rov qab thiab qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Rov qab stretching feem ntau yog siv rau ntau yam stretches tom qab thawj stretch. Cov khoom uas tau nthuav tawm tsis yooj yim rau wrinkle. Nws yog haum rau qhov sib sib zog nqus conical los yog hemispherical qhov chaw (xws li cov teeb pom kev zoo), thiab qee zaum nws kuj tsim nyog rau kev ncab ntawm qhov chaw cylindrical. Lub tensile coefficient ntawm daim duab rov qab yog 10 ~ 15 feem pua tsawg dua li ntawm kev kos duab pem hauv ntej, thiab lub zog tensile loj dua li ntawm kev kos duab pem hauv ntej, thiab phab ntsa ntawm qhov tuag yog thinner. Qhov tsawg kawg nkaus txoj kab uas hla ntawm lub nruas tom qab thim rov qab tuaj yeem ncav cuag (30 ~ 60) t, thiab qhov tsawg kawg nkaus fillet vojvoog ntawm thim rov qab tuaj yeem ncav cuag (2 ~ 6) t. Yog li ntawd, rov qab kos duab yog ib txoj kev ua lag luam zoo heev, thiab qhov zoo ntawm cov khoom kuj zoo heev.
Qhov zoo thiab tsis zoo daim duab tuag ntawm hemispherical qhov chaw yog ua tiav nyob rau hauv ib qho stroke ntawm punch xovxwm. Nyob rau hauv cov xwm txheej uas tsis muaj ob txoj kev xuas nrig ntaus, tus tuav ruaj yog siv los nias lub ntug. Cov qauv no yog tsim rau cov punch stretching zoo tib yam, tom qab ncab lub kheej kheej yam tsis muaj wrinkles, qhov loj me.
Rau qhov thim rov qab daim duab tuag nrog cov lus qhia, cov khoom tiav ib nrab yog muab tso rau hauv qhov concave tuag qhov, thiab tom qab ntawd qhov khoob yog nias los ntawm convex thiab concave tuag, thiab tom qab ntawd cov punch nkag mus rau hauv qhov convex thiab concave tuag qhov, thiab lub workpiece. yog kos thiab tsim nyob rau hauv thim rov qab. Cov khoom yog ua si los ntawm tus pas nrig thiab lub phaj thawb los ntawm qhov tuag.
5. Stretch lub trimming tuag
Kos ntug txiav tuag yog ib qho kev xuas nrig ntaus tuag uas yog tsim los ntawm kev kos duab thiab txiav ntug ntawm tib txoj hauj lwm ntawm qhov tuag nyob rau hauv ib qho stroke ntawm lub punch xovxwm. Cov tuag yog tsim rau qhov ntiav ntiav nrog me me tensile thickness thiab qis qhov siab.
6. Multilayer tuag kos duab tuag
Thaum cov zis loj, txhawm rau txhim kho kev ua haujlwm ntawm kev ua haujlwm, feem ntau muab ob lossis peb zaug ntawm tensile tuag rau ntawm lub hauv paus tuag, kev siv lub tensile punch los ntawm ntau txoj haujlwm sib txawv ntawm kev tuag rau kev tsim tensile tas li, ua kom tiav ib tus naj npawb ntawm cov txheej txheem tensile.
