Kev soj ntsuam ntawm Cov Hom Kev Sib Tham hauv Stamping Parts Stretching Processes: Ib qho kev nthuav dav ntawm Cov Ntsiab Cai thiab Daim Ntawv Thov Scenario

Hauv kev ua cov hlau niaj hnub no, kev kos duab stamping yog cov txheej txheem tseem ceeb uas siv dav hauv tsheb, hluav taws xob, thiab kev lag luam aerospace. Los ntawm kev sib xyaw ntawm cov pwm thiab cov khoom siv stamping, cov 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

I. Cylindrical Drawing: Ib qho yooj yim thiab siv tau zoo

Cylindrical daim duab yog ib qho ntawm ntau hom kev kos duab kos duab, tsim rau kev tsim khoom cylindrical nrog flanges. Nws cov yam ntxwv muaj xws li cov flanges tiaj tus thiab hauv qab, axisymmetric sidewalls, thiab tsis sib xws deformation faib. Piv txwv li, cov kaus poom hlau thiab cov tes tsho hauv cov khoom siv niaj hnub feem ntau siv cov txheej txheem no. Cov ntsiab lus tseem ceeb muaj xws li: Kev kos duab deformation ntawm qhov khoob hauv thaj tsam flange yuav tsum tsis sib xws kom tsis txhob muaj qhov sib npaug; Rau qhov sib sib zog nqus cylindrical qhov chaw, ntau qhov kev kos duab yuav tsum tau ua los tiv thaiv cov khoom wrinkling lossis tawg.

II. Conical Drawing: Ib Qhov Kev Sib Tw Dual ntawm Qhov tob thiab Lub Kaum

Kev kos duab conical yog siv los tsim cov thawv conical lossis pyramidal, xws li funnels thiab teeb. Vim yog qhov loj ntawm qhov tsis muaj kev txhawb nqa ntawm qhov khoob thiab lub vojvoog me me ntawm lub khob hliav qab apex, hom kev ua haujlwm no yog qhov yooj yim rau hauv zos thinning lossis tawg. Cov kev daws teeb meem suav nrog:

1. Stepped stretching txoj kev: Cov dawb paug yog thawj stretched mus rau hauv ib tug stepped kev hloov ib feem, ces nthuav mus rau hauv lub cone puab;

2. Npuag tuav thiab kos cov hlaws dai: Ua kom muaj zog radial tensile kom tsis txhob wrinkling.

Cov txheej txheem nyuaj ntawm lub khob hliav qab- zoo li qhov seem nce nrog qhov tob (h / d piv) thiab lub khob hliav qab (), xav tau kev tswj xyuas meej ntawm kev tshem tawm thiab cov xov tooj ntawm kev ncab.

III. Rectangular stretching: Deformation sib txawv ntawm cov npoo ncaj thiab rounded fab

Rectangular stretching feem ntau yog siv los tsim cov duab plaub qhov qis. Nws tus yam ntxwv yog hais tias lub stretching kuj nyob rau hauv lub round ces kaum nyob rau hauv lub flange deformation cheeb tsam yog ntau dua li ntawm cov npoo ncaj, uas ua rau ntau deformation ntawm lub rounded fab. Cov kev sib tw yog: Qhov sib txawv ntawm cov yas deformation ntawm cov npoo ncaj thiab cov kab sib npaug yuav tsum tau sib npaug los ntawm kev tsim tuag; Sidewall instability yuav tsum tau zam thaum lub sij hawm ntau stretching.

Cov duab plaub siab xav tau cov duab plaub re-stretching, uas nws cov qauv deformation zoo ib yam li qhov sib sib zog nqus cylindrical qhov chaw, tab sis qhov kev ntxhov siab ntawm cov kauj ruam hloov pauv xav tau kev xav ntxiv.

IV. Complex Shape Stretching Processes: Composite Forming thiab Precision Control

1. Vaj huam sib luag Stretching txheej txheem
Haum rau cov ntawv hlau stampings nrog cov duab ntawm qhov chaw nyuaj (xws li ntsuas vaj huam sib luag thiab cov vaj huam sib luag zoo nkauj). Nws cov khoom tsim yog ib qho kev sib sib zog nqus ntawm cov duab kos thiab bulging, uas ua rau muaj kev tsis sib haum xeeb deformation, yuav tsum muaj siab -precision tuag thiab ntau- chaw nres tsheb xovxwm.

2. Flange-Txhim kho Hemispherical Stretching txheej txheem
Thaum stretching spherical qhov chaw, qhov dawb paug tsuas yog ib feem hu rau sab saum toj ntawm lub punch, yooj yim ua rau localized thinning los yog wrinkling. Cov kev daws teeb meem suav nrog kev ua kom lub zog ntawm lub cev tsis muaj zog lossis siv cov txheej txheem thim rov qab.

3. Thinning Stretching txheej txheem
Los ntawm kev txo cov punch- tuag tshem tawm, cov khoom siv phab ntsa lub tog raj kheej yog thinned thaum lub sij hawm ncab, yog li tshem tawm cov phab ntsa thickness sib txawv thiab txhim kho qhov smoothness. Cov txheej txheem no feem ntau yog siv rau hauv kev tsim cov khoom siab -cov thawv ntim khoom (xws li cov kaus poom).

V. Cov txheej txheem tshwj xeeb: Rov qab Stretching thiab Curved Surface Forming

Rov qab Stretching txheej txheem: Lub workpiece los ntawm cov txheej txheem yav dhau los yog stretched nyob rau hauv lub opposite kev taw qhia, nce radial tensile kev nyuaj siab los tiv thaiv wrinkling, thiab muaj peev xwm nce lub stretching coefficient. Tsim nyog rau kev tsim cov thawv sib sib zog nqus- zoo li qhov chaw.

Curved Surface Forming: Los ntawm tsis yog - ncaj-walled, tsis yog - tiaj tus- qauv pwm hauv qab, lub flange sab nraud ntawm qhov khoob yog txo qis thaum lub flange sab hauv txuas ntxiv, ua ib qho nkhaus hollow. Cov ntawv thov ib txwm muaj xws li automotive lub cev panels thiab irregularly zoo li lub plhaub.

VI. Cov lus pom zoo xaiv: Yuav ua li cas kom phim cov txheej txheem thiab cov kev xav tau?

1. Khoom Thickness thiab Plasticity: Cov ntaub ntawv nyias (t / d < 0.15) yuav tsum muaj ntau yam stretching lossis ntug nias; siab - cov ntaub ntawv plasticity (xws li stainless hlau) yog qhov tsim nyog rau kev sib sau ua ke.

2. Khoom Qhov tob thiab Zoo: Sib sib zog nqus- kos qhov chaw (h / d > 0.8) yuav tsum tau hloov pauv lossis thim rov qab; tsis yog -axisymmetric qhov chaw (xws li ellipses thiab dome duab) yuav tsum tau segmented tswj ntawm deformation.

3. Cov khoom siv thiab cov nqi: Ntau qhov ncab nce cov txheej txheem nyuaj, yuav tsum tau ntau - chaw nres tsheb xovxwm; thinning stretching yuav tsum tau pwm precision heev thiab yog haum rau siab -precision daim ntaub ntawv.

Cov txheej txheem ntawm stamping ib feem stretching yog ntau haiv neeg, xws li los ntawm cov qauv cylindrical yooj yim mus rau complex curved nto thiab thinning stretching. Txhua tus txheej txheem muaj nws cov xwm txheej thiab cov kev cov nyom. Hauv kev tsim khoom tiag tiag, cov kev daws teeb meem zoo tshaj plaws yuav tsum raug xaiv los ntawm kev xav txog cov khoom siv, cov khoom zoo, thiab cov kev xav tau precision. Nyob rau hauv lub neej yav tom ntej, nrog rau nrov ntawm kev txawj ntse tsim technologies, stamping thiab stretching txheej txheem yuav txhim kho mus rau ntau dua efficiency thiab precision, tsis tu ncua tsav tsheb txawj tej yam ntxiv nyob rau hauv lub manufacturing kev lag luam.
