Kev taw qhia ntawm alloy rims

Cov tsheb npoo tau raug muab faib ua cov hlau thiab cov phom rub los ntawm cov ntaub ntawv. Nrawm nrov tshaj plaws nyob rau hauv txoj kev hloov ua lag luam yog ntawm chav kawm alloy rims. Cov npoo hlau sib cais ua ob hom: Casting and forging.

Raws li kev tsim ntau txoj kev, cov rims yog cov muab faib ua ob pawg: Casting thiab forging. Casting faib ua ob hom: Lub ntiajteb txawj nqus casting thiab low pressure casting. Lub ntiajteb txawj nqus casting yog ib txoj hauv kev uas muaj cov kua xau tag nrho rau hauv lub khob kom txias thiab tsim tau. Vim yog cov txheej txheem tsim kev lag luam thiab lub pwm ntawm lub pwm, nws yog tus nqi qis tshaj txoj kev tsim. Siv tshuab muaj pes tsawg los siv lub zog me me los nias rau cov kua poom rau hauv pwm, yog tias cov khoom faib tawm ntawm cov qauv yog qhov nruab nrab, cov xuab zeb qhov me me, thiab cov duab tuaj yeem nyuab dua thiab ua kom zoo dua.

Lub ntug yuav muab faib ua ib qho thiab ntau daim ntawm qhov taw tes ntawm kev pom. Qhov ntau rims, txheej thav duab thiab tus spokes, yog nyias tau nyias thiab sib tw ua ke. Lawv yog ib qho ntawm cov hloov rims tam sim no muaj nyob rau hauv Suav teb. Qhov zoo dua yog hais tias nws yog yooj yim los tsim nyob rau hauv ib tes, vim hais tias cov sab nrauv muaj peev xwm dov li nrog hlau nplooj ntawv; ntawm lwm tes, nws yog yooj yim rau cov txij nkawm thiab ntau tus qauv kev sib hloov, piv txwv li, tus xov ntawm tus qauv qub tau nruab nrog ntau dav thiab sib txawv txheej txheem, uas ntxiv kom txo tau cov nqi. Muaj ntau lub tsho ntawm cov rims tseem tshuav kim tshaj ib nrab rims vim ntau qhov chaw, ntau cov kauj ruam ntau lawm, thiab pom ntawm ntau, thiab pom ntawm lub npoo qis dua, tab sis cov rims ntawm ntau daim feem ntau hnyav zog. Thiab lub rigidity yog tsis piv rau lub forged phim.
