Copper alloy extrusion kub
Kev txiav txim siab extrusion kub ntawm tooj liab alloys
Tooj liab thiab tooj liab alloys yuav tsum muaj tsawg deformation kuj thiab zoo plasticity ntawm extrusion kub. Qhov tsim nyog extrusion kub ntau yam yuav tsum tau txiav txim siab raws li daim duab plasticity, recrystallization daim duab, thiab daim duab theem ntawm cov hlau, thiab txiav txim siab qhov tseeb ntawm cov khoom.
(1) Cov cua kub kub feem ntau yog 0.75 ~ 0.95 npaug ntawm qhov kub ntawm qhov kub ntawm cov hlau. Lub sab sauv txwv ntawm extrusion kub ntau yam tuaj yeem txiav txim siab raws li cov ntsiab lus melting ntawm cov hlau thiab hlau thiab cov khoom theem taw tes kub ntawm cov hlau ntawm cov kab kos kom tsis txhob kub thaum lub sij hawm extrusion. Brittleness (overheating, overburning tshwm sim). Qhov qis qis ntawm extrusion kub ntau yam yuav tsum xav txog cov yas zoo ntawm qhov kub thiab txias thiab yuav tsum tau xyuas kom meej tias cov deformation tsis kam ntawm cov hlau thiab alloys tsis siab dhau.
(2) Rau cov alloys uas tau hloov pauv theem ntawm qhov kub thiab txias, nws yog qhov zoo tshaj plaws los ua kub extrusion nyob rau hauv ib-theem cheeb tsam.
(3) Kub extrusion yuav tsum tau nqa tawm ntawm qhov kub thiab txias nyob rau hauv high-temperature yas cheeb tsam kom ntau li ntau tau kom tsis txhob transverse tawg. Tab sis tib lub sij hawm, cov khoom nto ntawm cov hlau ntawm qhov kub thiab txias yuav tsum tau txiav txim siab los tiv thaiv oxidation ntau dhau los yog kev sib txuas ntawm cov ingot nto. Lub viscosity ntawm qee cov alloys rau cov cuab yeej nce nrog qhov kub thiab txias, xws li tooj liab dawb, txhuas bronze, thiab lwm yam. Xav txog kev siv qis kub extrusion ntau li ntau tau. Tsis tas li ntawd, lub peev xwm extruder kuj yuav tsum tau txiav txim siab thaum txiav txim siab qhov kub ntawm extrusion. Thaum siv cov extrusion qis dua, cov ton loj extruder yuav tsum tau siv.
(4) Lub luj tshib extrusion deforms heev thiab lub deformation ceev ceev. Kev sib txhuam ntawm cov hlau thiab cov cuab yeej yuav tsim kom muaj cua sov ntau, uas tuaj yeem ua rau qhov kub thiab txias ntawm qhov ingot nce thaum lub sij hawm extrusion txheej txheem. Thaum txiav txim siab qhov kub thiab txias, sim siv qhov kub thiab txias
Tsawg txwv nyem.
(5) Cov khoom sib txawv tuaj yeem tau txais los ntawm extruding ntawm qhov kub thiab txias. Thaum xaiv qhov kub extrusion, qhov kev ua tau zoo ntawm cov khoom yuav tsum raug txiav txim siab. Thaum ib co alloys extruded ntawm qhov kub thiab txias, tus Tsov tus tw shrinks ntev dhau lawm thiab lub siab residue nce, xws li HPb 59-1, thiab lwm yam. Thaum extruding tooj dag, qhov kub thiab txias yog heev tsawg, thiab strips yog yooj yim tsim nyob rau hauv lub kawg ntawm cov khoom extruded.
Cov duab, deformation degree, cuab yeej kub, lubrication tej yam kev mob, thiab lwm yam ntawm extruded khoom muaj ib tug tej yam kev cuam tshuam rau extrusion kub.
