Kev tsim cov tuag castings yuav tsum xav txog xya yam: tuag casting phab ntsa thickness, casting fillets thiab lub kaum sab xis, txhawb cov tav, casting qhov thiab yam tsawg kawg nkaus nyob deb ntawm qhov mus rau cov npoo, lub kaum sab xis qhov thiab slots, inserts, thiab machining nyiaj.
Casting Fillet Design Specifications
Feem ntau, txhua qhov chaw ntawm qhov tuag casting yuav tsum sib tshuam nrog cov fillets (tshwj tsis yog ntawm qhov chaw sib cais). Qhov no tso cai rau cov hlau du 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 lub 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 ntxig ntxig yuav tsum muaj qhov zoo tshaj plaws muaj grooves, protrusions, lossis knurling. 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 hais tias muaj qhov hnyav electrochemical corrosion ntawm lub casting thiab qhov ntxig, qhov ntxig nto yuav tsum muaj txheej tiv thaiv plating. Thaum kawg, castings nrog inserts yuav tsum zam kev kho cua sov kom tsis txhob ntim cov kev hloov pauv los ntawm theem kev hloov pauv 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, tus tsim ntawm tuag castings yuav tsum ua raws li lub hauv paus ntsiab lus ntawm minimizing phab ntsa thickness thiab tswj cov niaj hnub phab ntsa thickness thaum kom muaj zog txaus thiab rigidity.
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 kev tuag castings tsis tau raws li cov kev xav tau ntawm cov khoom kos duab, cov tuam txhab yuav tsum xub xav txog kev siv cov txheej txheem tiav xws li straightening, polishing, extrusion, thiab shaping los kho lawv. Yog tias cov txheej txheem 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 hauv Tuag Castings
Thaum tsim cov tuag castings, cov qauv tsim cov kaum sab xis yuav tsum suav nrog hauv cov qauv. Yog tias tsis muaj cov qauv tsim qauv, cov txheej txheem txheej txheem yuav tsum tau muab qhov tsim nyog. Cov kev taw qhia ntawm lub kaum sab xis yuav tsum ua raws li qhov kev taw qhia demolding ntawm lub casting.
