Lub hauv paus ntsiab lus ntawm engravure lub tog raj kheej Sib Tsoo Txheej Txheem: Sib tsoo (sib tsoo log sib tsoo txheej txheem) ua tiav lub hom phiaj ua tiav los ntawm kev txav ntawm tus txheeb ze ntawm lub log sib tsoo thiab qhov chaw ua haujlwm. Nws cov txheej txheem tseem ceeb yog tias thaum cov khoom abrasive ntawm qhov sib tsoo lub log nto tuaj rau hauv kev sib cuag nrog lub workpiece nto, kev sib hloov ntawm lub log sib tsoo ua rau cov txheeb ze ceev. Qhov txheeb ze ceev no ua rau cov khoom abrasive ua staggered txiav thiab sib tsoo ntawm qhov chaw ua haujlwm, yog li ua tiav cov txiaj ntsig ua haujlwm. Kev sib tsoo log, raws li lub cev muaj zog, tsis yog tsuas yog xa tawm lub zog thiab lub zog, tab sis kuj ua haujlwm txiav, sib tsoo thiab polishing ua haujlwm tib lub sijhawm. Cov txheej txheem no ua kom cov txheej txheem ua tiav thiab ua tiav qhov zoo ntawm qhov chaw ua haujlwm.
Sib tsoo log sib tsoo txheej txheem daim duab 1
Sib tsoo log sib tsoo txheej txheem daim duab 2
Lub hauv paus ntsiab lus ntawm kev sib tsoo: Lub rotogravure luam ntawv lub tog raj kheej ua cov txheej txheem tooj liab sib tsoo tuaj yeem muab faib ua peb theem: zawv zawg, plowing thiab txiav, uas yog txiav, sib tsoo thiab polishing.
1.Qhov cuam tshuam ntawm kev hloov ntawm cov txheej txheem sib tsoo ntawm qhov chaw ua haujlwm nto roughness thiab zoo: 1. Kev cuam tshuam ntawm kev sib hloov ceev ntawm workpiece nto roughness thiab zoo: Thaum lwm yam xwm txheej tsis hloov, raws li lub workpiece rotation ceev nce, khawb ntawm lub workpiece. nto ua ntev thiab lub workpiece nto zoo txo.
2. Kev cuam tshuam ntawm kev sib tsoo log kev sib hloov ceev ntawm workpiece nto roughness thiab zoo: Thaum lwm yam kev mob tseem tsis tau hloov, raws li kev sib tsoo log sib hloov ceev, kev txiav thiab polishing cuam tshuam nce, thiab workpiece nto zoo txhim kho.
3. Kev cuam tshuam ntawm kev sib tsoo log sib tsoo siab ntawm qhov chaw roughness thiab zoo ntawm lub workpiece: Thaum lwm yam kev mob tseem tsis tau hloov, raws li kev sib tsoo lub log sib tsoo siab, kev txiav thiab polishing cuam tshuam nce, thiab qhov zoo ntawm lub workpiece txhim kho.
4. Kev cuam tshuam ntawm kev sib tsoo log txav ceev ntawm workpiece nto roughness thiab zoo:
Thaum lwm yam kev mob tseem tsis tau hloov pauv, raws li kev txav mus los ntawm kev sib tsoo lub log nce ntxiv, qhov txiav quab yuam txo qis thiab qhov chaw ua haujlwm nto zoo txo.
Cov kev sib raug zoo ntawm kev sib hloov ceev thiab nto roughness nyob rau hauv cov txheej txheem sib tsoo, uas yog, lub zog ntawm kev sib hloov ceev ntawm lub sib tsoo log thiab lub workpiece nyob rau saum npoo roughness ntawm lub workpiece yog xam raws li nram no: 1. kev sib tsoo log, cov nplej ntau abrasive dhau los ntawm cov av hauv av ib lub sijhawm, thiab yog li qhov me dua qhov roughness tus nqi ntawm lub workpiece nto. Nyob rau tib lub sijhawm, qhov siab dua qhov kev sib hloov ceev ntawm kev sib tsoo lub log, qhov ntau dua yog tias qhov kev nthuav tawm ceev ntawm cov yas deformation ntawm cov hlau saum npoo yuav ntau dua qhov kev txiav ceev, thiab cov khoom siv ua haujlwm yuav tsis muaj sijhawm los deform. , uas ua rau txo qis ntawm cov yas deformation ntawm cov hlau nto, thiab qhov roughness tus nqi ntawm cov hniav sib tsoo yuav txo. 2. Cov nyhuv ntawm lub workpiece kev sib hloov ceev ntawm qhov chaw roughness tsuas yog qhov cuam tshuam ntawm cov nyhuv ntawm kev sib tsoo log ceev. Thaum lub workpiece kev sib hloov ceev nce, tus naj npawb ntawm cov nplej abrasive hla hauv av hauv ib lub sij hawm txo qis, thiab tus nqi ntawm qhov roughness yuav nce. 3. Lub sij hawm mus txawv teb chaws ntawm kev sib tsoo lub log yuav txo qis, thiab tus naj npawb ntawm lub sij hawm ntawm txhua qhov chaw ntawm lub workpiece nto yog rov qab los ntawm kev sib tsoo lub log nce, thiab tus nqi roughness ntawm cov av saum npoo yuav txo. Ntawm qhov tsis sib xws, tus nqi roughness ntawm cov av saum npoo yuav nce. Workpiece nto sib tsoo zoo tswj thiab sib tsoo log ua hauj lwm lub hauv paus ntsiab lus: 1. Cov xuab zeb nplej nyob rau hauv lub sib tsoo log yog randomly faib, disorderly thiab tsis sib xws, thiab yuav pom tau li ntau txhiab riam ntse. Thaum lub sij hawm sib tsoo, qhov txiav ntug hloov tsis tu ncua thiab ua blunt. Lub blunted sib tsoo lub log txuas ntxiv mus vim qhov sib tsoo quab yuam tseem nce ntxiv. Thaum lub zog sib tsoo tshaj qhov sib txuas ntawm lub binder, cov nplej abrasive yuav txiav tawm. Qhov no yog hu ua "self-detachment" ntawm kev sib tsoo log; txoj kev sib tsoo ntawm lub log sib tsoo yog rov ua cov txheej txheem no. 2. Txhua qhov ntawm lub workpiece nto yog rov ua dua los ntawm kev sib tsoo lub log. Lub kaum sab xis thiab kev taw qhia ntawm cov cim kos tshwm sim los ntawm kev sib tsoo lub log ntawm ib cheeb tsam ib puag ncig yog qhov tsis tu ncua, thiab qhov loj thiab qhov tob ntawm cov cim kos yog random thiab tsis tuaj yeem ntsuas qhov tseeb. 3. Tus naj npawb ntawm zawv zawg thiab zawv zawg quab yuam ib cheeb tsam ntawm lub workpiece nto ncaj qha cuam tshuam qhov roughness ntawm lub workpiece thiab qhov zoo ntawm qhov layout. Tus naj npawb ntawm zawv zawg yog proportional rau cov zawv zawg kab tsim ntawm qhov layout thiab inversely proportional rau roughness; zawv zawg quab yuam yog proportional rau roughness. Qhov saum npoo roughness ntawm steel-raws li workpieces yog proportional rau roughness ntawm txheej tom qab electroplating. 4. Tus naj npawb ntawm zawv zawg kev sib txhuam thiab zawv zawg quab yuam ib chav tsev ntawm qhov chaw ua haujlwm tuaj yeem tswj tau los ntawm kev kho cov txheej txheem sib tsoo.
