Kev txhaj tshuaj peening

① Txhaj peening ntxiv dag zog thiab kev npaj rau tshuaj oxidation zaj duab xis tsim. Xuab zeb blasting kev kho mob yog ua nyob rau saum npoo ntawm cam khwb cia txhuas qhov chaw, txawm hais tias nws muaj peev xwm tshem tawm cov roj stains, oxide nplai, thiab burrs nyob rau saum npoo, thiab tsim compressive kev nyuaj siab rau ntawm qhov chaw kom ua tau kom muaj zog. Tab sis qhov saum npoo yog ntxhib thiab tsis muaj xim hlau luster.

Txawm hais tias alkaline degreasing corrosion daws kev kho mob ntawm 70-90 degree tuaj yeem ntxuav tau zoo ntawm qhov chaw ntawm cam khwb cia txhuas, lub sij hawm degreasing corrosion tsis yooj yim los tswj vim qhov sib txawv ntawm qhov chaw ntawm cov khoom, suav nrog cov khoom tsis yog machined thiab ua tiav. Yog hais tias cov roj tshem tawm corrosion lub sij hawm ntev dhau lawm, tsis sib xws corrosion feem ntau tshwm sim. Tsis tas li ntawd, kev tshem tawm cov roj ntau dhau thiab kev xeb kuj tuaj yeem ua rau saum npoo ntawm qhov chaw ntxhib thiab tsis muaj hlau nplaum, thiab tsis tuaj yeem tsim kom muaj kev ntxhov siab los txhawb qhov chaw.

Cov txheej txheem no siv cov pob iav rau kev txhaj tshuaj peening. Cov iav spherical txhaj tshuaj tsuag rau saum npoo ntawm cam khwb cia txhuas qhov chaw tsis tsuas yog tshem tawm cov roj stains, oxide nplai, thiab lwm yam, tab sis kuj ua rau ntau qhov chaw me me rau ntawm qhov chaw. Tom qab lub teeb pom kev zoo, nws nthuav tawm cov xim hlau nplaum, thiab qhov roughness ntawm qhov chaw tau zoo tuaj. Tsis tas li ntawd, txhaj tshuaj peening tuaj yeem tsim kom muaj kev ntxhov siab rau ntawm qhov chaw, txhim kho lub neej qaug zog ntawm qhov chaw, txo qhov rhiab heev ntawm qhov chaw rau kev ntxhov siab corrosion, thiab zoo heev ntxiv dag zog rau qhov chaw ntawm qhov chaw. Qhov chaw kho nrog tshuaj oxidation tuaj yeem tsim kom muaj txheej txheej tuab thiab ci oxide zaj duab xis, ua tau raws li cov khoom tsim qauv. Yog li ntawd, peb xaiv tua peening raws li cov txheej txheem ua ntej kho rau tshuaj oxidation zaj duab xis tsim.

Cov iav pob txhaj tshuaj peening feem ntau tswj cov tshuaj tsuag qhov deb kom yog 200-350 hli, lub kaum sab xis txau yuav yog 60-70 degree , thiab lub siab txau yog 5kg / mm2. Ua tib zoo saib xyuas kom tsis txhob muaj cov tshuaj tsuag ntev ntev ntawm cov cheeb tsam hauv cheeb tsam ntawm qhov chaw.
