Dab tsi yog qhov txheej txheem ntawm qhov concave tuag?
Kev ua kom siv cov khoom tuag, kev ua cov khoom loj dua, cov khoom siv hlau khib nyiab, cov khoom siv thiab cov khoom cua sov yog qhov nyuaj, rau daim ntawv thov ntau tshaj 45 mn carbon steel thiab 40 lossis 45 lossis cr, 38 crmoala yim hlau hlau. Raws li muaj nyob hauv daim duab. 2-21 (a), tus txheej txheem kev txiav txim siab ua concave tuag nrog 45 hlau yog raws li nram no.
1. Txwv tsis pub tuag, tshem tawm ntawm 100 ^ 1 nyiaj nyiaj pab raws li qhov loj ntawm daim duab.
2. Lub billets yog ua los ntawm kev kho cua sov ncaj qha.
3. Tso mos ab thiab kos cov cim kab contour ntawm txoj kev tuag.
4. Nyob rau hauv daim ntawv ntawm planer concave tuag, tawm ib finance nyiaj ntawm 2-3 mm.
5. Muab cov tsheb ntxhib ntxig rau hauv nruab nrab, tso qhov seem ntawm 2 - 3 hli.
6. Tshawb kom sov sov, kev txias txias 235 ~ 275H3.
7.Cov khoom tsim ua cov cim kab contour raws li daim duab loj.
8.Radial thiab concave tuag ntawm txhua sab kom loj.
9. Qhov so 0.25-0.35mm yog sab laug nyob rau hauv qhov concave tuag ib feem ntawm lub tsheb thauj mus los precision tsheb.
10. Cov ciaj ciam nyob rau hauv txhua feem ntawm mould yog kos los ntawm cov ciaj.
11.heat treatment, concave qauv kab noj hniav qhov chaw tawv hardness 50 mus rau 55 HRC.
12. fitter hniav sib tsoo kab phev concave qauv, pneumatic sib tsoo lub log sib tsoo muaj, thiab ces siv cov zeb zeb sib tsoo, reoccupy metallographic sandpaper hniav sib tsoo.The granularity ntawm sandpaper yuav tsum tau tuab tuab thiab ces zoo.Cov sib tsoo yuav tsum tau nqa tawm hauv cov kev taw qhia perpendicular mus rau kev taw qhia ntawm lub cim ntawm txoj kev dhau los, kom txog rau thaum lub riam cim tau raug tshem tawm, thiab tom qab ntawd ces sib tsoo yuav tsum tau nqa tawm ntawm kev coj mus rau kev coj ua thawj kev sib tsoo.Thaum kawg kev sib tsoo, kev taw qhia ntawm kev sib tsoo yuav tsum zoo ib yam nrog rau kev coj ntawm cov khoom muag demoulding, thiaj li ua kom yooj yim rau txoj kev demoulding.Tom qab kev sib tsoo, lub roughness Ra ntawm kab noj hniav nto yuav tsum tsis ntau dua 0.25um.
13. Txhua feem ntawm lub rooj ntev zaum drill tapping txhob lo lo ntxhuav.
14.Qhov ib feem ntawm txoj hlua khi tawm.
