Kev tsim cov bronze loj bushings

Sawv daws yeej paub qhov ntawdbronze bushingmuaj siab hardness thiab zoo hnav tsis kam. Lawv tsis yooj yim rau tom, thiab lawv kuj muaj kev ua tau zoo casting thiab machinability. Nws muaj zog corrosion kuj. Tom qab ntawd nws kuj tseem ceeb heev hauv kev tsim khoom. Yog li dab tsi peb yuav tsum xyuam xim rau hauv nws cov txheej txheem tsim khoom?

Loj bronze bushing

Thawj taw tes: Thaum casting bronze bushing, txhua txoj kev yuav tsum tau ua tib zoo tuav. Piv txwv li, cov tub ntxhais yuav tsum tau muab tso ncaj ncaj thaum lub thawv sib sau ua ke, kom tsis txhob muaj cov khoom cam khwb cia los ntawm kev ua tsis tau raws li qhov loj me vim qhov no.

Lub ntsiab lus thib ob: Ua ntej ua tiav, cov casting yuav tsum tau muab ntxuav ua ntej, tom qab ntawd thauj khoom, calibrated ua ntej, thiab tom qab ntawd tshem tawm thaum cov khoom tiav tiav tiav thiab txias. Vim bronze muaj shrinkage, thiaj li yuav ua tau kom raug lub workpiece, nws yuav tsum tau re-loaded thaum nws muab tso rau hauv chav tsev kub.

Qhov thib peb point: Tom qab cov khoom tiav, tshwj xeeb tshaj yog lub tes tsho ncaj tsis tuaj yeem muab tso rau hauv tiaj tus, nws yuav tsum tau muab tso rau ntsug kom tsis txhob deformation.

Plaub taw tes: Ntim, tawm ib qho nyiaj kom tsis txhob deformation los ntawm kev sib tsoo thaum lub sijhawm thauj mus los.
