Txau cov txheej txheem hmoov rau cov fittings thiab li qub rmt

Hais txog cov tshuaj tsuag cov txheej txheem hmoov ntawm li qub / fittings, peb muaj tshuaj tsuag lub khw hmoov. Ntawm no peb yuav qhia cov kev ua txaus rau cov neeg tuaj saib.

1, Kev Ntsuas Xyuas Txoj Cai

Cov hmoov txheej zoo yog txau rau saum npoo ntawm cov hmoov ua kom txau cov khoom. Nyob rau hauv qhov kev txiav txim ntawm cov cua sov cua sov, cov hmoov yuav muaj kev sib txuam ntawm cov npoo ntawm qhov chaw ua haujlwm los ua cov hmoov av. Cov hmoov txheej zoo yog kho los ntawm kub ci thiab leveling, thiab ua txheej kawg nrog cov teebmeem sib txawv; Cov Txau Txau yog qhov zoo dua rau cov txau txheej txheem hauv cov tshuab zog, hluav taws xob tsis kam thiab laus tsis kam.

2, Nto Setreatment. (xws li li qub, fittings)

Qhov zoo ntawm cov txheej txheem kev kho ua ntej cuam tshuam rau qhov zoo ntawm hmoov txheej zaj duab xis, thiab kev kho mob ua ntej yooj yim kom poob tawm, bubbling thiab lwm yam tshwm sim. Yog li ntawd, kev ua haujlwm ua ntej yuav tsum tau them siab rau.

Kev tiv thaiv (tseem hu ua masking).

Yog tias qee qhov chaw ua haujlwm tsis tas yuav muaj cov txheej txheej, nws tuaj yeem them nrog cov kua nplaum tiv ua ntej kom tsis txhob muaj cov xim txau

Sov.

Yog tias qhov tuab tuab yuav tsum muaj, qhov ua haujlwm tuaj yeem yog preheated rau 200 ~ 230 ° C, uas tuaj yeem nce cov tuab ntawm txheej.

3, Kho kom zoo nkauj los ntawm ci.

Cov tshuaj txau workpiece yog rhuab nyob rau hauv lub tshuab ziab khaub ncaws ntawm 180 ~ 200 ℃ los ntawm kev ua kom sov (15-20 feeb) kom sov, yog li tau txais cov nyhuv saum npoo uas peb xav tau. (Hmoov sib txawv yog ci ntawm ntau qhov kub thiab sijhawm). Qhov no yuav tsum tau sau tseg hauv kev kho cov txheej txheem.

4, huv si

Tom qab txheej txheej tau kho, tshem tawm cov khoom tiv thaiv thiab txiav cov burrs.

5, tshuaj xyuas

Tom qab kho lub workpiece, lub ntsiab niaj hnub niaj hnub zoo nkauj (txawm hais tias tus du thiab ci, shrinkage qhov tsis xws luag) thiab tuab (tswj hauv 55 ~ 90μm). Kho lossis rov txau cov ua haujlwm tau kuaj nrog tolekage, pinholes, doog, npuas thiab lwm yam tsis xws luag.

6, ntim

Cov khoom tiav tiav tom qab tshuaj xyuas tau cais thiab muab tso rau hauv lub tsheb thauj khoom thiab cov yeeb yaj kiab ntim khoom thiab hnav khaub ncaws kom tiv thaiv thiab hnav (tuaj yeem ntim raws li cov neeg siv khoom).

Cov khoom sib txawv muaj cov txheej txheem sib txawv, yog tias koj muaj cov lus nug cuam tshuam, thov hu rau peb, peb yuav teb koj hauv lub sijhawm.
