Stamping qhov chaw tsis zoo thiab tiv thaiv
Hais txog ntau yam tsis xws luag ntawm stamping qhov chaw tsim los ntawm stamping factories, peb tau soj ntsuam ntau lub ntsiab lus hauv thawj ob kab lus. Niaj hnub no, peb yuav ua tib zoo saib cov laj thawj thiab kev tiv thaiv ntawm ob peb qhov kawg ntawm qhov tsis zoo stamping.
9. Txoj hauj lwm ntawm lub qhov khoob hloov thaum khoov
1) Yog vim li cas
Qhov loj ntawm lub qhov yog tsis ncaj ncees lawm, (bending thiab nro thinning);
Qhov sib txawv ntawm lub siab (khoov qhov siab tsis txaus, zawv zawg zawv zawg, rov ua dua, khoov dav hlau hloov pauv tshwm sim);
Thaum txoj kab khoov thiab kab nruab nrab ntawm ob lub qhov tsis sib luag, qhov khoov qhov siab yog tsawg dua qhov tsawg kawg nkaus qhov siab.
Qhov ze ntawm txoj kab bending yog feem ntau deformation.
2) Kev tiv thaiv
Kev ntsuas ntawm ntau lub plawv ua rau:
Xyuas kom tseeb tias qhov siab ntawm sab laug thiab txoj cai yog qhov tseeb;
Kho cov dowel pins thiab dowel daim hlau;
Txo springback kom ntseeg tau tias qhov sib luag thiab flatness ntawm ob qhov chaw nkhaus;
Hloov cov txheej txheem txoj kev, thawj khoov khoov thiab tom qab ntawd xuas nrig ntaus.
Nws nthuav tawm qhov kev ua si sab nraud-qhib
Xyuas kom meej qhov tsawg kawg yog dabtsi yog khoov qhov siab H (H Ntau tshaj los yog sib npaug rau R ntxiv 2t t khoom thickness R dabtsi yog khoov vojvoog);
Hloov cov duab ntawm lub tshuab ua haujlwm kom poob qhov qis dua qhov tsawg kawg nkaus khoov qhov siab yam tsis muaj kev cuam tshuam rau kev siv.
Lub qhov nyob ze ntawm txoj kab khoov yog yooj yim los tsim deformation ntsuas:
Nyob rau hauv kev tsim ntawm dabtsi yog khoov qhov chaw los xyuas kom meej tias los ntawm lub dabtsi yog khoov ib feem mus rau lub qhov ntug qhov deb X loj dua ib tug tej yam nqi X Ntau tshaj los yog sib npaug rau (1.5-2.0) tt dabtsi yog khoov phaj thickness;
Lub qhov auxiliary yog tsim los ntawm qhov dabtsi yog khoov kom nqus cov bending deformation kev nyuaj siab, uas tuaj yeem tiv thaiv qhov deformation ntawm lub qhov nyob ze ntawm txoj kab dabtsi yog khoov. Feem ntau, lub tswv yim ntawm kev khoov ua ntej xuas nrig ntaus yog saws.
10. Tom qab cov khoom yog khoov, qhov khoov yog pom tseeb thinner
1) Kev tiv thaiv
The bending radius is too small relative to the plate thickness (r/t>3 txoj cai lub kaum sab xis bending) feem ntau nce lub vojvoog dabtsi yog khoov;
Multi-angle dabtsi yog khoov ua rau qhov khoov qhov nyias nyias thiab loj dua. Yuav kom txo qis thinning, ib lub kaum sab xis thiab ntau txheej txheem khoov txoj kev yog saws kom deb li deb tau.
Thaum siv lub kaum ntse ntse punch, cov punch nkag mus rau qhov tuag tob heev thiab qhov tuab ntawm qhov khoov yog pom tseeb txo qis.
11. Flanges ntawm daim duab qhov chaw wrinkle nyob rau hauv tus txheej txheem ntawm kev kos duab
1) Yog vim li cas
Flange tuav quab yuam me me dhau los tiv thaiv kev ntxhov siab ntau dhau tangential; Thiab ua rau tangential deformation, yog li poob stability tom qab tsim ntawm wrinkles. Cov khoom siv thinner kuj yooj yim dua los tsim wrinkles.
2) Kev tiv thaiv
Ua kom lub zog tuav ntawm tus tuav thiab nce lub thickness ntawm cov khoom tsim nyog.
12. Ua rau thiab tiv thaiv phab ntsa tawg ntawm qhov sib sib zog nqus kos duab
1) Yog vim li cas
Lub radial tensile stress ntawm cov khoom thaum lub sij hawm sib sib zog nqus nqus yog loj heev.
Die fillet radius me dhau;
Tsis zoo sib sib zog nqus nqus lubrication;
Cov khoom siv raw muaj cov yas tsis zoo.
2) Kev tiv thaiv
Txo tuav quab yuam;
Ua kom lub vojvoog ntawm qhov tuag fillet;
Kev siv cov lubricants kom raug;
Xaiv cov khoom siv nrog cov kab zoo dua los yog ua kom cov txheej txheem annealing hauv kev cob qhia.
13. Hauv qab ntawm daim duab sib sib zog nqus yog torn
1) Yog vim li cas
Die fillet radius yog me me dhau lawm, kom cov khoom nyob rau hauv lub xeev txiav.
2) Kev tiv thaiv
(feem ntau tshwm sim nyob rau hauv thawj theem ntawm kev sib sib zog nqus daim duab) nce lub vojvoog ntawm cov fillet tuag thiab ua kom nws du. 0.2µm.
14. Lub ntug ntawm qhov sib sib zog nqus daim duab yog tsis sib xws thiab wrinkled
1) Yog vim li cas
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 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. tawg tawm ntawm 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 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.
2) Kev tiv thaiv
Reposition qhov tuag, kho lub vojvoog ntawm qhov tuag fillet thiab qhov sib txawv ntawm qhov tuag thiab tuag kom qhov loj me txawm tias ua ntej muab tso rau hauv kev tsim khoom (txo qis lub vojvoog ntawm qhov tuag fillet lossis siv cov khoom nkhaus nkhaus kom tshem tawm cov quav).
15. Tapered qhov chaw lossis hemispherical qhov chaw wrinkle ntawm lub duav thaum lub sij hawm sib sib zog nqus nqus
1) Yog vim li cas
Thaum pib ntawm kev sib sib zog nqus nqus, feem ntau ntawm cov khoom yog nyob rau hauv lub xeev ncua kev kawm ntawv, ntxiv rau lub tuav quab yuam yog me me heev, qhov tuag fillet vojvoog yog loj dhau los yog siv roj nplua nyeem ntau dhau. Lub radial tensile kev nyuaj siab txo qis thiab cov khoom yuav tsis ruaj khov thiab wrinkled nyob rau hauv qhov kev txiav txim ntawm tangential compressive kev nyuaj siab.
2) Kev tiv thaiv
Ua kom lub zog tuav tsis muaj zog lossis siv lub calendering bar qauv, txo lub vojvoog ntawm qhov tuag fillet los yog ua kom cov khoom tuab me ntsis.
