Kev ncab kev sib sau yog cov txheej txheem stamping uas siv ib tus tuag los ua kom zoo li lub tiaj tiaj mus rau hauv qhov qhib, khoob. Kev ncab yog ib qho ntawm cov txheej txheem stamping thiab muaj cov ntawv thov dav. Kev ncab tuaj yeem tsim cov nyias-}}}}} duab dhos ua ke, plaub fab, sheral, conical, parabolic, thiab lwm cov duab tsis xwm yeem. Thaum ua ke nrog lwm cov txheej txheem stamping, nws kuj tseem tuaj yeem tsim cov khoom sib xyaw ntau ntxiv.
Ncab sib sau siv cov khoom siv stamping suav nrog: ncab, rov - ncab, rov qab ncab ncab, thiab thib ncab.
Ncab: Siv lub siab phaj ntaus thiab punching lub zog ntawm ib qho punch, ib feem lossis tag nrho cov ntawv tiaj tus yog kos rau hauv cov thawv concave, sib sau cov thawv hauv qab. Ua qhov uas lub thawv ntim qhov twg sib npaug yog sib txuas rau txoj kev ncab kom ncab cov txheej txheem yog qhov yooj yim ncab. Txawm li cas los xij, ncab ntawm conical (lossis pyramidal) ntim, hemispherical ntim, thiab cov thawv hauv parabolic kuj tseem muaj kev nthuav dav.
RE - Kos duab: Qhov no yog hais tias cov txheej txheem ntawm re ...- kev ua haujlwm ntawm qhov tob ntawm cov thawv ntim.
Rov qab kos duab: Qhov no cuam tshuam nrog cov txheej txheem kos duab ntawm cov kauj ruam dhau los, tig sab hauv ib sab ntawm cov cheeb tsam thiab txo nws txoj kab uas hla.
Kev nqus cov tawv nqaij: Cov txheej txheem no siv cov thawv ntim rau hauv lub thawv concave me dua li lub thawv hauv qab thiab ib txhij thinning phab ntsa tuab. Qhov no tshem tawm phab ntsa thickness sib txawv thiab ua rau lub thawv ntim du.
Thaum siv cov khoom siv stamping rau hlau stamping thiab cov txheej txheem kos duab, cov 16 hom hauv qab no suav nrog:
1. Kos duab cylindrical
✦ (puag ncig kos duab):
Teeb duab flangred cylindrical khoom. Ob lub flange thiab hauv qab yog lub planar, cov sib xws cylindrical, thiab deformation yog formualed ntawm tib lub ncig ntawm qhov khoob ntawm cov flange ntawm cov flange.
2. Ellipse kos duab
✦ (ellipse kos duab):
Qhov deformation ntawm cov flange ntawm cov flange yog tensile deformation, tab sis tus nqi thiab piv ntawm deformation sib txawv raws li raws cov duab contour. Qhov ntau dua tus nkhaus, qhov ntau dua cov yas cais tawm ntawm seem; Hloov siab, tus me dua ntawm curvature, tus me dua cov khoom deformation.
3. Kwv yees duab kos duab
✦ (duab plaub):
Ib lub rawv me me ntu uas muaj los ntawm ib - lub sijhawm kos duab. Thaum lub sij hawm kos duab, lub tensile tsis kam ntawm cov sib npaug ntawm thaj chaw flormation, thiab cov qib ncaj ntawm kev sib dhos yog ntau dua li ntawm cov npoo ncaj.
4. Lub roob kos duab
✦ (Hill Draw):
Thaum lub hau ntawm cov stamped yog inclined ib qho yog inclined, toftall raug tshem tawm thaum lub sijhawm stamping thiab tsis ua raws li cov pwm kom txog thaum kawg tsim. Qhov tsis zoo ntawm cov chaw sib txawv ntawm cov khoom seem tsis yog tib yam thaum sib sau.
5. Lub roob nraaj:
Qhov deformation ntawm qhov tsis txaus ntseeg thaum lub toj txheej txheem ntawm lub toj {{} Daim npog tensile, tab sis ib tus txheej txheem sib xyaw ua ke nrog ob lub tensile thiab bulging deformation. Qhov deformation ntawm qhov dawb paug nyob saum npoo av yog tensile (tshwj xeeb yog qhov tsis muaj kev ntxhov siab (tshwj xeeb yog qhov kev ntxhov siab hauv paus) yog qhov kev ntxhov siab tensile).
6. Flange hemisphere kos duab:
Thaum nqus tau ib qho kev sib tw spherical, cov neeg sib tham tau dawb paug rau sab saum toj ntawm cov punch, thaum cov feem ntau ntawm qhov tsis muaj kev tshem tawm, tsis muaj kev tshem tawm lub xeev. Yog li ntawd, cov teeb meem tseem ceeb hauv kev kos duab xws li thinning ntawm thaj chaw tiv tauj hauv zos lossis qhov tsis txaus thiab wrinkling ntawm qhov nkhaus.
7. Flange teeb duab:
Qhov no yuav suav nrog kev kos duab flange ntawm cov khoom kos. Nws cov kev ntxhov siab - Cov cwj pwm zoo ib yam li cov neeg muaj hluav taws xob. Vim muaj kev ntxhov siab rau kev ntxhov siab, wrink yog nquag tshwm sim; Yog li ntawd, txoj kev txwv tsis pub tshaj yog tsuas yog txwv los ntawm kev sib zog ua wrinkling.
8. Ntug Duab
✦ (Flange Teeb Duab):
Qhov no yuav cuam tshuam re- Nyeem lub flange ntawm cov khoom uas tau kos nyob rau hauv cov txheej txheem yav dhau los los tsim cov duab angular. Tus txheej txheem no yuav tsum muaj cov khoom siv kom muaj cov ntsej muag zoo.
9. Sib sib zog nqus duab
(Sib sib zog nqus duab):
Cov khoom tshaj li kev kos duab txwv yuav tsum muaj ntau daim duab ua haujlwm (ob lossis ntau dua) kom ua tiav cov txheej txheem. Cov khoom lag luam uas muaj undergone tob kos duab hauv theem dhau los yog re6- kos hauv qhov tob. Rau cov flange flange cov kab, cov kab ntawm flange tau tiav thaum thawj daim duab, thiab nyob twj ywm tsis hloov pauv ntawm kev kos duab tom ntej.
10. Taper Teeb Duab
✦ (Taper Drug):
Rau cov ntu sib sib zog nqus nrog H / D> 0.8 thiab {= 10℃-30 degree, vim yog qhov loj kawg nkaus deformation. Qhov kev tsim lub zog yog pauv tsuas yog los ntawm thaj chaw sib tiv toj hauv cheeb tsam nruab nrab thiab cov punch, yooj yim coj mus rau ntau thinning thiab txawm tawg ntawm qhov seem hauv qee thaj chaw. Ntau yam kev hloov yuav tsum tau ua tiav li ntawm cov duab me me. Cov txheej txheem kos duab ua ntej ua ntej ua ntej tsis muaj qhov sib txuas lus, nrog cov duab hloov mus rau sab hauv ntawm cov duab tapered, thaum kawg nthuav tawm los ua cov duab tapered. Tus naj npawb ntawm cov txheej txheem kos thiab cov txheej txheem rau theem hloov pauv yog tib yam li rau cov sylindrical feem.
11. Rectangular Redrawing
✦ (Cov Rectangular Redrawing):
Qhov deformation ntawm cov txheej txheem plaub loj tsim los ntawm ntau cov kev kos duab sib txawv tab sis kuj tseem muaj ntau yam ntawm lub box tsawg {{}} zoo qhov chaw. Daim duab 1 - 46 qhia cov kev hloov pauv ntawm ib feem ntawm cov teeb duab sib dhos xws li cov duab sib cav sib ceg rau cov duab sib dhos siab.
12. Nto Taus
✦ (Deg txoj kev):
Txoj kev sib tw saum npoo av uas shrining sab nraud flange feem ntawm cov khoom siv hlau uas tsis yog tiaj tus -} bineed.
13. Kauj ruam kos duab
✦ (Theem Kos):
Qhov pib kos cov khoom ntawm sab laug yog redrawn los tsim cov kav hauv qab ntawm sab xis. Cov ntu tob tob deform nyob rau hauv thaum ntxov ntawm kev kos duab, thaum lub hiav txwv ntiav mos txwv tshwj xeeb tom qab. Shear kev nyuaj siab yog yooj yim ua rau nyob rau ntawm ntug kev ntawm theem ntaiv, ua rau muaj kev cuam tshuam.
14. Rov qab kos duab
✦ (Cov duab rov qab):
Lub workpiece uas tau undergone ib txheej txheem kos duab dhau los yog rov qab - Kos duab, ib hom kev txiav txim siab. Rov qab kos duab nce radial tensile muaj kev ntxhov siab, uas muaj txiaj ntsig hauv kev tiv thaiv wrinkling. Nws kuj tseem tuaj yeem nce redrawing coefficient.
15. Thinning thiab cov txheej txheem kos duab
✦ (ironing):
Tsis zoo li cov duab kos, thinning thiab duab feem ntau hloov cov phab ntsa tuab ntawm kev kos ib feem thaum lub sij hawm kos duab. Qhov sib txawv ntawm cov punch thiab tuag yog me dua li cov kab thickness me me. Txoj cai ncaj phab ntsa ntawm seem yog nyob rau hauv ntau dua kev ntxhov siab compressive ntxhov siab vim nws kis los ntawm kev sib txawv. Thaum lub sij hawm kos duab, lub phab ntsa tuab txo qis, tshem tawm cov phab ntsa tuab, nce sab du, thiab txhim kho qhov tseeb thiab lub zog.
16. Vaj Huam Sib Luag Teeb Duab
✦ (Vaj Huam Sib Luag Teeb Duab):
Vaj huam sib luag cov khoom yog daim ntawv hlau bookings nrog cov npoo sib txawv. Nyob rau hauv cov txheej txheem kos duab, qhov tsis muaj kev cuam tshuam hauv kev nyuaj; Nws tsim cov khoom tsis yooj yim kos duab, tab sis ib tus txheej txheem sib xyaw ua ke nrog ob qho tib si sib sib zog nqus duab thiab kev sib tsoo.
