Straightening ntawm castings, tseem hu ua kev kho los yog rectification, yog ib tug tseem ceeb kauj ruam nyob rau hauv cov txheej txheem tsim los xyuas kom meej tias cam khwb cia hlau qhov chaw raws li meej qhov ntev specifications thiab structural kev ncaj ncees.
Txoj Kev Ncaj Ncees
Muaj ntau txoj hauv kev ua haujlwm ncaj qha rau cov castings, txhua qhov tsim nyog rau ntau hom khoom thiab cov duab casting. Cov txheej txheem tseem ceeb muaj xws li:
Mechanical Straightening: Qhov no suav nrog kev siv lub zog sab nraud siv cov cuab yeej siv tshuab thiab tshuab. Cov txheej txheem xws li nias, khoov, thiab rauj yog ib txwm muaj. Mechanical straightening yog tshwj xeeb tshaj yog zoo rau cov loj thiab ruaj khov castings.
Thermal Straightening: Nyob rau hauv txoj kev no, tshav kub yog siv rau tej qhov chaw ntawm lub casting kom induce thermal expansion los yog contraction, yog li kho distortions. Txoj kev no yog qhov zoo rau cov castings uas muaj kev cuam tshuam rau kev tawg lossis tawg hauv kev ntxhov siab.
Hydraulic Straightening: Siv hydraulic presses, txoj kev no siv cov kev tswj siab kom ncaj castings. Nws muaj precision siab thiab haum rau cov ilv thiab complex duab uas yuav tsum tau ceev faj tuav.
Kev sib xyaw ua ke: Feem ntau, kev sib xyaw ua ke ntawm cov tshuab thiab thermal straightening yog ua haujlwm kom ua tiav cov txiaj ntsig xav tau, tshwj xeeb tshaj yog nyob rau hauv castings nrog complex geometries thiab cov khoom sib txawv.
Kev faib tawm thiab xaiv cov khoom siv ncaj nraim
Qhov kev xaiv ntawm cov khoom siv ncaj nraim yog nyob ntawm ntau yam, nrog rau hom casting, cov khoom siv, thiab qhov deformation. Cov khoom siv tseem ceeb yog:
Phau Ntawv Qhia Ncaj Ncees: Cov cuab yeej yooj yim xws li hammers, anvils, thiab handheld presses yog siv rau kev kho me me lossis me me. Lawv xav tau cov neeg ua haujlwm txawj kom ua tiav cov txiaj ntsig tau meej.
Mechanical Presses: Cov no muaj xws li toggle presses, ntsia hlau presses, thiab eccentric presses. Lawv haum rau nruab nrab mus rau loj castings thiab muab kev siv zog sib xws. Mechanical presses raug xaiv rau lawv txoj kev ntseeg tau thiab yooj yim ntawm kev ua haujlwm.
Hydraulic Presses: Cov xovxwm no muaj peev xwm muaj peev xwm ua tau siab thiab tswj tau meej ntawm kev siv siab. Lawv yog cov zoo tagnrho rau straightening loj, hnyav, thiab complex castings. Hydraulic presses yuav haum nrog ntau yam tuag thiab fixtures kom haum raws li cov duab sib txawv thiab ntau thiab tsawg.
Kev kho cua sov rauv: Siv nyob rau hauv thermal straightening, cov furnaces tso cai rau kev tswj cua sov ntawm castings induce stress nyem thiab kho deformations. Lawv yog ib qho tseem ceeb rau castings uas tsis tuaj yeem tiv taus txhua yam quab yuam.
Straightening Tuag
Straightening dies, tseem hu ua kev kho tuag, yog cov cuab yeej tsim tshwj xeeb uas siv nrog rau cov xovxwm kom raug hloov kho deformed castings. Lawv tau categorized raws li lawv txoj haujlwm thiab hom casting lawv siv rau:
Flat Tuag: Cov no yog siv rau straightening tiaj tus nto thiab npoo. Lawv yog cov yooj yim hauv kev tsim tab sis muaj txiaj ntsig zoo rau kev kho cov qauv kev sib txawv.
Txoj Kev Tuag: Tsim kom phim cov contour ntawm cov casting, cov tuag no yog siv los kho cov duab thiab nkhaus. Lawv yog cov kev cai tsim rau cov qauv tsim tshwj xeeb thiab xyuas kom meej hauv kev ncaj.
Txhawb Tuag: Cov tuag no muab kev txhawb nqa thiab stabilization rau lub casting thaum lub sij hawm straightening txheej txheem. Lawv yog ib qho tseem ceeb rau kev tiv thaiv ntxiv deformations lossis kev puas tsuaj thaum kho.
Kev xaiv ntawm txoj kev tuag ncaj yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig xav tau. Nws yuav tsum phim lub casting's geometry thiab qhov xwm ntawm qhov distortion los muab kev kho kom zoo yam tsis muaj kev ntxhov siab ntxiv lossis kev puas tsuaj.
Straightening ntawm castings yog txheej txheem tseem ceeb hauv kev ua kom zoo thiab ua haujlwm ntawm cov hlau qhov chaw. Los ntawm kev siv cov txheej txheem tsim nyog, xaiv cov cuab yeej tsim nyog, thiab siv cov khoom ncaj ncaj tuag, cov tuam ntxhab tuaj yeem kho deformations thiab tsim cov castings uas ua tau raws li cov qauv kev cai. Qhov no tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov khoom kawg nkaus xwb tab sis tseem txuas ntxiv nws lub neej kev pabcuam, ua kom ntseeg tau thiab cov neeg siv khoom txaus siab.
