Tsim Specifications Rau Tuag Castings
Kev tsim cov tuag castings yuav tsum xav txog xya yam: phab ntsa thickness, casting fillets thiab lub kaum sab xis, txhawb cov tav, casting qhov thiab qhov tsawg kawg nkaus nyob deb ntawm qhov mus rau ntug, lub qhov thiab cov qhov, inserts, thiab machining nyiaj.
Tsim Specifications rau Casting fillets
Feem ntau, txhua qhov chaw ntawm kev tuag casting yuav tsum muaj cov fillets (tshwj tsis yog ntawm qhov chaw sib cais) kom ntseeg tau tias cov hlau ntws zoo thaum lub sij hawm txhaws, ua kom cov pa khiav tawm, thiab tiv thaiv cov kab nrib pleb los ntawm cov kaum ntse ntse. Rau kev tuag castings xav tau electroplating thiab txheej, fillets tso cai rau cov txheej txheem plating thiab tiv thaiv cov xim pleev xim ntawm cov ces kaum ntse. Lub vojvoog fillet R ntawm tuag castings feem ntau yuav tsum tsis pub tsawg tshaj 1 hli, nrog rau qhov tsawg kawg nkaus fillet vojvoog ntawm 0.5 hli.
Tsim Specifications rau Inserts hauv Tuag Castings
Ua ntej, tus naj npawb ntawm cov ntxig rau hauv qhov tuag casting yuav tsum tsis txhob ntau dhau. Qhov thib ob, kev sib txuas ntawm qhov ntxig thiab qhov tuag casting yuav tsum ruaj khov, thiab cov grooves, protrusions, knurling, thiab lwm yam. Thib peb, cov khoom ntxig yuav tsum zam cov kaum ntse ntse kom yooj yim rau kev tso thiab tiv thaiv kev ntxhov siab hauv qhov casting. Yog tias muaj qhov hnyav electrochemical corrosion ntawm lub casting thiab qhov ntxig, qhov ntxig nto yuav tsum muaj txheej tiv thaiv. Thaum kawg, castings nrog inserts yuav tsum zam kev kho cua sov kom tsis txhob ntim cov kev hloov pauv los ntawm theem hloov ntawm ob lub hlau, uas tuaj yeem xoob qhov ntxig.
Tsim Specifications rau Tuag Casting Phab Ntsa Thickness
Nyias-walled tuag castings muaj zog dua thiab ceev zoo dua li tuab-walled sawv daws yuav. Yog li ntawd, lub hauv paus ntsiab lus tsim rau kev tuag castings yuav tsum yog: thaum ua kom muaj zog txaus thiab rigidity, phab ntsa tuab yuav tsum tau txo qis thiab ua kom zoo ib yam. Kev xyaum tau pom tias phab ntsa tuab ntawm 2.5-4mm feem ntau haum rau kev tuag castings; qhov chaw nrog phab ntsa thickness tshaj 6 hli yuav tsum tsis txhob raug tsim siv tuag casting. Qhov cuam tshuam ntawm cov phab ntsa tuab heev lossis nyias nyias ntawm kev ua haujlwm zoo: Yog tias cov phab ntsa casting nyias dhau ntawm qhov tsim, nws yuav ua rau cov hlau tsis zoo, cuam tshuam ncaj qha rau lub zog casting thiab ua rau txoj kev nyuaj. Cov phab ntsa tuab heev lossis tsis sib xws yog qhov ua rau shrinkage thiab tawg. Tsis tas li ntawd, raws li cov phab ntsa thickness nce, qhov tsis xws luag xws li porosity thiab shrinkage kuj nce, zoo ib yam li txo cov casting zog thiab cuam tshuam zoo.
Tsim Specifications rau Machining Allowances hauv Tuag Castings
Feem ntau, vim muaj kev txwv ntawm cov txheej txheem tuag casting, thaum qee qhov qhov tseeb, qhov roughness, lossis geometric tolerances ntawm tuag castings tsis tau raws li qhov yuav tsum tau ntawm cov khoom kos duab, cov tuam txhab yuav tsum xub txiav txim siab siv txoj kev ua tiav xws li straightening, polishing, extrusion, thiab shaping los kho lawv. Yog tias kev ua tiav tsis tuaj yeem daws tau cov teeb meem no, qee qhov ntawm qhov tuag casting yuav tsum tau machined. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum machining, ib qho me me machining nyiaj yuav tsum raug xaiv, thiab qhov chaw tsis cuam tshuam los ntawm txoj kab sib faib thiab cov khoom txav yuav tsum tau siv raws li qhov chaw seem seem kom ntau li ntau tau kom tsis txhob cuam tshuam qhov tseeb ntawm machining.
Tsim Specifications rau Draft Angles ntawm Tuag Castings
Thaum tsim cov tuag castings, cov qauv tsim cov kaum sab xis yuav tsum tau suav nrog hauv cov qauv. Yog tias tsis muaj cov qauv tsim qauv, cov txheej txheem cov kaum sab xis rau demolding yuav tsum tau muab thaum tsim nyog. Cov kev taw qhia ntawm lub kaum sab xis yuav tsum ua raws li qhov kev taw qhia demolding ntawm lub casting.
