Txhaj MoldingRooj vag
Nws yog channel txuas lub ntsiab khiav (los yog ceg khiav) thiab kab noj hniav. Qhov chaw hla ntu ntawm cov channel tuaj yeem sib npaug rau lub ntsiab ntws channel (lossis ceg channel), tab sis feem ntau nws txo qis. Yog li ntawd nws yog qhov tsawg tshaj plaws nyob rau hauv qhov chaw ntawm tag nrho cov khiav. Cov duab thiab qhov loj ntawm lub rooj vag muaj kev cuam tshuam zoo rau qhov zoo ntawm cov khoom.
Lub luag haujlwm ntawm lub rooj vag yog:
A. Tswj cov khoom ntws ceev:
B. Nws tuaj yeem tiv thaiv kev thim rov qab vim qhov ua tiav ntxov ntawm cov yaj uas khaws cia hauv qhov no thaum txhaj tshuaj:
C. Cov yaj uas dhau los ua rau muaj zog shear kom qhov kub thiab txias, yog li txo qhov pom tseeb viscosity thiab txhim kho fluidity:
D. Nws yog qhov yooj yim rau kev cais cov khoom thiab cov kev khiav haujlwm. Kev tsim ntawm lub rooj vag zoo, qhov loj thiab txoj hauj lwm nyob ntawm qhov xwm ntawm cov yas, qhov loj thiab cov qauv ntawm cov khoom.
Lub Cross-sectional Shape ntawm lub rooj vag:
Feem ntau, cov duab ntoo ntawm lub rooj vag yog cov duab plaub lossis lub voj voog, thiab qhov chaw hla ntu yuav tsum me me thiab qhov ntev yuav tsum luv. Qhov no tsis yog tsuas yog raws li cov teebmeem saum toj no xwb, tab sis kuj vim tias nws yooj yim dua rau cov rooj vag me me kom loj dua, thiab nws nyuaj rau cov rooj vag loj kom ntsws. Lub rooj vag qhov chaw yuav tsum feem ntau xaiv qhov twg cov khoom yog thickest yam tsis muaj kev cuam tshuam cov tsos. Tus tsim ntawm lub rooj vag loj yuav tsum coj mus rau hauv tus account lub zog ntawm cov yas yaj.
Kab noj hniav yog qhov chaw hauv pwm rau molding cov khoom yas. Cov khoom siv los ua cov kab noj hniav yog sib sau ua ke hu ua molded qhov chaw. Txhua qhov molded feem ntau muaj lub npe tshwj xeeb. Cov molded qhov chaw uas tsim cov duab ntawm cov khoom yog hu ua concave pwm (tseem hu ua poj niam pwm), uas tsim cov duab puab ntawm cov khoom (xws li qhov, qhov, thiab lwm yam) yog hu ua cores los yog punches (tseem hu ua txiv neej pwm. ). Thaum tsim molded qhov chaw, tag nrho cov qauv ntawm cov kab noj hniav yuav tsum xub txiav txim siab raws li cov khoom ntawm cov yas, geometry ntawm cov khoom, qhov ntev tolerances thiab yuav tsum tau siv. Qhov thib ob yog xaiv qhov chaw seem, txoj haujlwm ntawm lub rooj vag thiab lub qhov cua thiab txoj kev demoulding raws li cov qauv txiav txim.
Thaum kawg, raws li qhov loj ntawm cov khoom tswj, kev tsim ntawm txhua qhov thiab kev sib xyaw ntawm txhua qhov yog txiav txim siab. Cov yas yaj muaj qhov siab siab thaum nws nkag mus rau hauv cov kab noj hniav, yog li cov molded qhov chaw yuav tsum tau xaiv kom tsim nyog thiab xyuas kom muaj zog thiab rigidity. Txhawm rau ua kom lub ntsej muag du thiab zoo nkauj ntawm cov khoom yas thiab yooj yim demoulding, roughness ntawm qhov chaw nyob rau hauv kev sib cuag nrog cov yas yuav tsum yog Ra> 0.32um, thiab nws yuav tsum yog corrosion-resistant. Cov khoom tsim feem ntau yog siv los kho cov cua sov kom nce hardness, thiab yog ua los ntawm corrosion-resistant steel.
