Hydraulic extrusion sib tsoo

Hydraulic extrusion sib tsoo yog ua kom semi-khoom abrasive extruded los ntawm tej qhov chaw (xws li lub siab chamber thiab dav hlau qhov), deburring, polishing thiab chamfering ntawm channel nto thiab ces kaum, raws li qhia nyob rau hauv daim duab 1. Lub tshuab muaj peev xwm tswj lub extrusion siab, abrasive. ntws thiab tshaj tawm. Ntau hom kev sib tsoo, qhov loj me, qhov ntom ntom thiab cov khoom thauj viscosity tuaj yeem siv los tsim cov kev sib txawv extrusion sib tsoo. Cov cab kuj feem ntau yog ib hom hloov tau yooj yim semi-khoom polymer, ntxiv ib qho ntawm cov khoom sib tov. High viscosity nyob ze-khoom nqa khoom yog siv kom sib npaug ntawm cov phab ntsa sab hauv thiab cov channel loj ntawm qhov chaw. Tsawg viscosity feem ntau yog siv rau kaum chamfering thiab me me channel sib tsoo. Thaum lub abrasive yog nyem rau hauv qhov txwv channel, viscosity ntawm abrasive nce, tuav cov txhuam kom ruaj khov rau hauv qhov chaw. Nyob rau hauv no viscosity, lub abrasive yuav zom cov hla dhau. Lub abrasive loj thickened los ntawm extrusion yog tawm los ntawm ib tug txwv channel, uas yog, lub qub viscosity yog rov qab, ua rau me me los yog tsis muaj kev sib tsoo. Abrasive viscosity, extrusion siab thiab qhov luaj li cas ntawm cov channel txiav txim siab qhov ntws ntawm abrasive, cuam tshuam rau qhov sib tsoo, sib tsoo uniformity, qhov loj ntawm kaum chamfering. Slow flow rate yog haum rau kev sib tsoo sib tsoo, siab txaus yuav ua rau lub kaum loj roundness. Extrusion siab ntau yog 0.7 ~ 22MPa, abrasive txaus tus nqi yog ntau tshaj 3801 / min. Feem ntau siv txhuam yog silicon carbide, tab sis cubic boron nitride, alumina thiab emery kuj muaj. Qhov loj ntawm cov xuab zeb hais li ntawm 0. 005 mus rau 1.5 hli. Cov xuab zeb zoo tuaj yeem ua tiav tiav. Qhov tob ntawm kev txiav los ntawm cov xuab zeb ntawm lub workpiece nyob ntawm qhov kev xaiv extrusion siab, abrasive viscosity thiab xuab zeb loj.
