Vim lub siab yield point, siab hardness thiab tseem ceeb txias ua hauj lwm hardening nyhuv ntawm stainless hlau nws tus kheej, cov yam ntxwv ntawm stainless hlau phaj dabtsi yog khoov yog raws li nram no:
1) Vim tias tsis zoo thermal conductivity thiab qis elongation piv nrog cov pa roj carbon zoo tib yam, lub zog deformation yuav tsum loj;
2) Piv nrog carbon steel, stainless hlau ntawv muaj ib tug muaj zog nyiam lub caij nplooj ntoos hlav rov qab thaum khoov;
3) Piv nrog carbon steel, stainless hlau phaj muaj qhov qis elongation tus nqi, thiab lub kaum sab xis bending R ntawm lub workpiece thaum khoov yog loj dua li ntawm cov hlau, txwv tsis pub tej zaum yuav muaj kab nrib pleb;
4) Vim lub siab hardness ntawm stainless hlau daim hlau thiab qhov tseem ceeb txias ua hauj lwm hardening nyhuv, cov cuab yeej steel nrog kub kho hardness saum 60HRC yuav tsum tau xaiv thaum xaiv xovxwm dabtsi yog khoov cov cuab yeej, thiab lawv nto roughness yog ib qho kev txiav txim ntawm qhov loj dua li cov pa roj carbon. steel xovxwm dabtsi yog khoov cuab yeej.
Raws li cov yam ntxwv saum toj no, feem ntau hais lus:
1. Nyob rau hauv chav tsev loj, lub phaj tuab, qhov ntau dua qhov yuav tsum tau khoov quab yuam, thiab raws li lub phaj thickness nce, cov npoo ntawm lub dabtsi yog khoov quab yuam yuav tsum loj dua thaum xaiv cov khoom siv khoov;
2. Raws li qhov loj me, qhov loj dua lub zog tensile, qhov me me ntawm qhov elongation, qhov loj dua qhov yuav tsum tau muaj zog dabtsi yog khoov, thiab qhov loj ntawm lub kaum sab xis;
3. Nyob rau hauv rooj plaub uas lub phaj thickness sib haum mus rau lub vojvoog dabtsi yog khoov nyob rau hauv tus tsim daim duab, raws li kev paub, qhov expansion loj ntawm ib tug dabtsi yog khoov workpiece yog ntxiv rau ntawm sab xis-angled sab rho tawm ob lub phaj thicknesses, uas muaj peev xwm ua tau raws li tag nrho. tsim cov kev xav tau raug, thiab qhov nthuav dav tuaj yeem suav tau raws li cov qauv empirical. Yooj yim rau kev suav cov txheej txheem thiab txhim kho kev ua haujlwm ntau lawm;
4. Qhov ntau dua lub zog ntawm cov khoom siv, qhov ntau dua elastic rov qab. Txhawm rau kom tau txais 90-degree kaum sab xis ntawm qhov khoov, lub kaum sab xis ntawm rab riam yuav tsum tau tsim kom me dua. Piv nrog carbon steel, stainless hlau nrog tib thickness muaj ib tug loj dabtsi yog khoov lub kaum sab xis. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov no, txwv tsis pub yuav muaj cov kab nrib pleb, uas yuav cuam tshuam rau lub zog ntawm lub workpiece.
Stainless hlau phaj dabtsi yog khoov springback ntsiab lus
Lub springback ntawm stainless hlau yog qhov teeb meem tiag tiag. ntsig txog ntau yam
1. Hardness: qhov hardness ntau dua, qhov rov qab ntau dua. Kuv siv 301-EH cov khoom zaum kawg, thiab qhov rov qab yog 14 degrees. 2. Qhov piv ntawm cov khoom thickness rau cov khoom thickness ntawm dabtsi yog khoov vojvoog: qhov loj dua qhov ratio, qhov ntau dua qhov rebound
3. SUS301 muaj qhov rov qab loj dua li SUS304. Nyob rau tib lub sijhawm, 304 muaj qhov rov qab me dua li 301 los ntawm 2 degrees. Tsis tas li ntawd, Nyiv lub 301 xav tias yuav rov zoo dua li Taiwan.
4. Kuj tseem muaj qhov sib txawv ntawm txoj kev molding. Lub springback ntawm ib-kauj ruam molding yog ntau dua li ntawm ntau moldings.
5. Kuv tus cwj pwm yog ua kom kho tom qab kev kuaj pwm, yuav hloov tau pes tsawg degrees, thiab xyuam xim rau lub rebound nrog lub kaum sab xis rebound thiab vojvoog rebound. Qhov xwm txheej tshwj xeeb raug tshuaj xyuas kom meej.
