1 Txoj Kev Tshawb Fawb

1.1 Tsim Framework

Cov txheej txheem txheej txheem tau teeb tsa los xyuas kom meej tag nrho cov khoom tsim tawm. Al6061 blocks tau machined siv 3-axis CNC zeb nrog cov cuab yeej ruaj khov, tswj cov spindle ceev, thiab cov dej txias tsis sib xws. Tus qauv tsim tau hais txog kev txiav lub zog tas li txhawm rau tshem tawm cov cuab yeej hnav hloov pauv.

1.2 Cov ntaub ntawv qhov chaw

Cov ntaub ntawv suav nrog cov ntaub ntawv roughness, anodizing-layer thickness ntsuas, qhov ntev hloov ua ntej thiab tom qab kev kho mob, thiab qhov cuam tshuam qhov tseem ceeb. Kev ntsuas cov ntaub ntawv tau sau hla tsib qhov kev sim rov ua dua rau ib pawg parameter.

1.3 Kev sim cov cuab yeej thiab cov qauv

1.3.1 Machining teeb

Cov txheej txheem 10 hli kawg zeb, 8000 rpm spindle ceev, thiab 600 mm / min pub tus nqi tau siv. Calibration blocks xyuas lub tshuab repeatability.

1.3.2 Surface-Preparation Instruments

iav-bead media (80-120 mesh) thiab 0.5-0.7 MPa siab ntau tau siv. Surface roughness testers thiab optical microscope validated Ra thiab qauv faib.

1.3.3 Anodizing System

Hom II sulfuric-acid anodizing tau ua ntawm 20℃nrog qhov ceev tam sim no. Txheej thickness yog ntsuas los ntawm eddy-tam sim no sojntsuam.

2 Kev Tshawb Fawb thiab Kev Tshawb Fawb

2.1 Nto Roughness Hloov

Table 1 summarizes txhais tau tias Ra ua ntej thiab tom qab sandblasting.

Table 1 Surface Roughness (Ra) Hloov

Qhov nce hauv Ra dlhos nrog cov ntaub ntawv uas twb muaj lawm ntawm cov hlaws-blast texturing, paub meej tias zoo ib yam matte-finish tiam.

2.2 Txheej Thickness thiab Dimensional cuam tshuam

Daim duab 1 qhia txog qhov nruab nrab anodizing thickness hla cov qauv.

Daim duab 1 Anodizing Txheej Thickness Distribution

Qhov nruab nrab thickness stabilized ntawm 12.4 µm. Dimensional ntsuas tau pom ib qho kev loj hlob sab nrauv piv rau cov qauv anodizing expansion qauv.

2.3 Sib piv nrog Kev Tshawb Fawb Txog Tam Sim No

Cov txiaj ntsig tau pom zoo sib xws ntawm kev hloov pauv hloov pauv tau tshaj tawm hauv kev tshawb fawb ntawm machining-surface, thaum txheej txheej txheej nthuav qhia qis dua qhov sib txawv vim yog tswj hwm ua ntej anodizing zoo nkauj. Cov txheej txheem kev sib xyaw ua ke txo cov xim blotching feem ntau pom hauv qhov chaw tsis kho.

3 Kev sib tham

3.1 Kev txhais cov ntsiab lus

Kev sib raug zoo ntawm cov xov xwm loj thiab Ra tau lees paub tias yuav muaj kev cuam tshuam rau tus cwj pwm. Uniform anodizing tau pab los ntawm lub zog zoo sib xws uas tau qhia los ntawm sandblasting.

3.2 Kev txwv

Cov ntaub ntawv raug txwv los ntawm cov khoom siv ruaj khov thiab ib qho kev kub ntxhov. Kev sim ntxiv hla qhov dav dav ntawm machining tsis tuaj yeem kho qhov dav dav.

3.3 Cov kev cuam tshuam

Cov neeg tsim khoom xav tau ob qho tib si kom zoo nkauj tiav thiab qhov tseeb tuaj yeem siv txoj hauv kev no los txo cov kev ua haujlwm rov qab thiab qhov tsis xws luag. Cov ntaub ntawv txhawb nqa nws qhov tsim nyog rau cov tsev neeg neeg hlau, cov khoom siv hluav taws xob siv hluav taws xob, thiab cov khoom siv sib xws.

Tswj sandblasting ua ke nrog hom II anodizing ntseeg tau tsim cov khoom sib xws thiab txheej txheej ntawm CNC-milled Al6061 Cheebtsam. Dimensional stability tseem nyob rau hauv tus qauv kam rau ua, thiab cov khoom nto ua tau raws li qhov yuav tsum tau ua rau kev ua haujlwm zoo thiab zoo nkauj. Kev ua haujlwm yav tom ntej tuaj yeem tshawb nrhiav kev tswj hwm kev tshaj tawm-kev faib tawm thiab kev sib piv nrog kev nyuaj-anodizing.
