Kos tuag rau cov punch sib txawv
Cov qauv ntawm cov duab kos yog txiav txim siab raws li cov duab geometric, qhov tseeb qhov tseeb, cov khoom siv, tawm los thiab cov xovxwm siv. Tensile tuag feem ntau kuj yooj yim, nws cov qauv raws li tensile kev taw qhia muaj rau pem hauv ntej tensile tuag thiab thim rov qab tensile tuag thiab ob qho tib si zoo thiab tsis zoo tensile tuag, raws li cov txheej txheem tensile tuaj yeem muab faib ua cov txheej txheem tensile tuag, ntau txheej txheem nruam tensile. tuag thiab puas tensile tuag, uas puas tensile tuag tau muab faib ua blanking tensile tuag thiab blanking tensile xuas nrig ntaus tuag; Raws li kev siv cov xovxwm sib txawv tuaj yeem muab faib ua ib qho xovxwm nrog kev kos duab tuag thiab ob npaug ntawm kev ua haujlwm xovxwm tuag, hu ua tus cwj pwm ntawm ib qho kev txiav txim siab ib qho kev kos duab tuag thiab ob qho kev ua punch kos duab tuag.
A, 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.
1. Kos qhov tuag thawj zaug hauv ib txheej txheem
Ib qho txheej txheem kev kos duab tuag yog kev kos duab tuag uas ua tiav ib txheej txheem hauv ib qho kev ua haujlwm stroke. Thawj daim duab tuag ntawm ib tus txheej txheem muaj ob yam ntawm tus tuav tsis muaj thiab tsis muaj tus tuav. Vim hais tias ntawm cov qauv yooj yim ntawm ib txheej txheem tensile tuag, nws yog feem ntau tsis siv phau ntawv qhia ntaus ntawv.
Forward drawing tuag qauv yam tsis muaj kev qhia tsis muaj tuav. Kev kos duab pem hauv ntej yog ib txoj hauv kev los kos cov punch txheeb ze rau pem hauv ntej. Nws yog siv los kos cov khoom nrog cov khoom tuab thiab qis dua qhov siab. Vim tias qhov deformation ntawm cov khoom me me, tsis tas yuav nqa lub nplhaib tuav. Thaum cov pwm raug teeb tsa, lub nplhaib ruaj ruaj yog thawj zaug muab tso rau ntawm lub punch tuag thiab lub concave tuag, lub nplhaib ruaj ruaj raug muab tshem tawm tom qab cov pwm tau nruj nrog cov punch xovxwm, thiab tom qab ntawd qhov khoob ntawm qhov pre-blanking yog muab tso rau nyob rau hauv lub puab qhov ntawm lub positioning phaj. Tom qab ncab, lub workpiece yog scraped tawm ntawm lub qhov kawg ntawm qhov tuag los ntawm elastic qhib.
Cov qauv ntawm ib qho yooj yim rau pem hauv ntej daim duab tuag nrog ib tug elastic dawb paug yas dhos yog txawv nyob rau hauv uas lub Upper tuag yog nruab nrog ib tug elastic blank tuav. Thaum ua haujlwm, qhov khoob yog muab tso rau hauv lub nplhaib tso thiab ncab hauv qab qhov kev txiav txim ntawm punch. Tom qab stretching, lub workpiece yog scraped tawm ntawm lub hauv qab ntawm qhov tuag 1 lub qhov ncauj.
Qhov rov qab kos duab tuag nrog tus tuav khoob yog ntau dua compact dua rau pem hauv ntej qauv. Lub 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 khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Lub pusher ntawm lub Upper tuag yog txoj kev tuag ntawm lub hauv qab ntawm daim duab. Cov qauv no muaj ntau dua rigidity thiab ua kom muaj qhov zoo ntawm qhov hauv qab. Thaum ua haujlwm, qhov khoob yog muab tso rau hauv lub nplhaib tuav. Vim tias qhov tuag tau txais cov khoom siv tawv tawv, nws muaj lub neej ua haujlwm ntev thiab tsim nyog rau ntau lawm.
2. Ncua lub pwm dua
Thaum qhov yuav tsum tau kos ob peb zaug, kos duab tuag tom qab thawj zaug tuaj yeem hu ua daim duab tuag dua.
Tuag rau daim duab thib ob yam tsis muaj ntawv qhia. Thaum ua hauj lwm, cov khoom semi-tiav lawm tsim nyob rau hauv cov txheej txheem dhau los yog muab tso rau ntawm lub punch rau qhov chaw. Thaum lub sab sauv tuag nrog lub punch slider, ua ntej los ntawm kev tsim lub ntsej muag kawg ntawm lub laub phaj nias semi-tiav flange nto, nyob rau hauv qhov kev txiav txim ntawm siab, paug phaj nrog lub Upper tuag nyob rau hauv siab, cov roj hmab tsis yog compressed, lub punch. nyob rau hauv lub concave tuag ntawm lub puab nto ntawm lub qhov tensile txoj kev. Thaum lub siab tuag nce siab, cov roj hmab compressed nce thiab thawb lub phaj tawm, thawb cov khoom tawm ntawm lub punch. Yog hais tias qhov seem tseem nyob rau hauv qhov tuag, lub forming pusher yog thawb nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav compression thawb ib feem tawm ntawm qhov tuag.
Txawb tuag daim duab tuag, nws yog qhov tsim nyog rau qhov siab thiab punch stroke me me, tsis txaus los nqa tawm lub voj voog, square seem ntawm nruab nrab txheej txheem ncab. Qhov tuag thiab qhov chaw phaj tuaj yeem txav rov qab mus rau hauv ob qho kev qhia. Thaum ua haujlwm, thawj zaug rub tawm lub concave tuag, thiab tom qab ntawd muab cov khoom ua tiav ib nrab ntawm cov txheej txheem dhau los rau hauv qhov chaw tso phaj, thiab tom qab ntawd thawb lub concave tuag mus rau qhov chaw nres tus pin. Lub workpiece tom qab tensile txoj kev raug tshem tawm los ntawm lub scraper nyob rau hauv qis ib feem ntawm qhov tuag.
3. Composite drawing tuag
Compound drawing tuag yog hais txog lub punch nyob rau hauv ib tug stroke, ntxiv rau ua kom tiav daim duab, tab sis kuj ua kom tiav lwm yam blanking ua hauj lwm.
Blanking, kos duab, xuas nrig ntaus composite tuag. Cov yam ntxwv ntawm cov qauv pwm yog tias nws muaj cov cuab yeej qhia kev ua haujlwm siab thiab cov khoom siv los tiv thaiv wrinkle crimping nplhaib, uas tuaj yeem ua kom lub blanking, stretching thiab punching clearance. Nws yog qhov tsim nyog rau qhov chaw nrog cov ntaub ntawv nyias nyias, tab sis kev sib tsoo yog qhov nyuaj. Txhawm rau kom tsis txhob pov tseg ntawm lub ntsej muag kawg ntawm lub punch thiab tsub zuj zuj hauv lub qhov ntawm lub punch, lub punch yog muab nrog lub caij nplooj ntoos hlav ejector qws kom tso cov khib nyiab los ntawm lub qhov hauv lub qhov ntawm cov ntsia hlau hauv cov khoom tsis. Thaum ua hauj lwm, lub unloading phaj thawj nias cov khoom, thiab ces los ntawm lub convex thiab concave tuag, tensile tuag, xuas nrig ntaus punch thiab qis tuag, tom qab ua tiav ntawm blanking stretching, xuas nrig ntaus. Thaum cov tuag saum toj nce, cov khoom raug thawb tawm los ntawm lub ru tsev nyob rau hauv qhov kev txiav txim ntawm qhov tsis muaj zog counter-elastic. Yog hais tias lub workpiece nyob rau hauv lub Upper tuag, lub workpiece raug tshem tawm los ntawm lub movable forming tuag.
Rectangular box blanking drawing tuag, nws yog haum rau siab lub duab plaub los yog siab cylindrical qhov chaw kos duab. Tsis muaj ib sab, tsuas yog ob sab ntawm sab ntawm cov khoom seem. Thaum blanking, ling khoom yuav txiav tawm los ntawm blanking flange, yog li tsis muaj paug phaj.
