Cov ntaub ntawv thiab cov khoom yuav tsum muaj rau kev txhaj tshuaj molding tshuab chim screws

Lub tshuab txhaj tshuaj molding tsis tu ncua txav cov khoom yas khaws cia hauv qhov funnel los ntawm qhov kev txiav txim ntawm lub thoob ntsia hlau. Nyob rau hauv kev sib xyaw ua ke ntawm cua sov thiab shearing, cov yas softens vim cua sov thiab dhau los ua lub xeev ntws. Tom qab ntawd, cov ntsia hlau rov qab siab hloov kho cov roj rov qab ceev, ntxiv hloov cov dej ntws ntawm cov yas hauv lub tshuab txhaj tshuaj molding kom cov yas tuaj yeem ua tau plasticized.

Cov ntaub ntawv thiab cov khoom siv rau kev txhaj tshuaj molding tshuab chim screws:

Cov khoom siv niaj hnub no suav nrog nitriding steel, 45 steel, 40Cr, 38CrMoAl, thiab lwm yam.
1. Nitrided steel thiab 38CrMoAl muaj cov khoom zoo tag nrho, yog li lawv tau siv dav. Feem ntau hais lus, lub thickness ntawm nitride txheej yuav tsum yog 0 4-0.6 millimeters. Txawm li cas los xij, cov khoom no muaj kev tiv thaiv corrosion tsawg thiab kim heev.

2. Ib qho txiaj ntsig zoo ntawm 45 steel khoom yog nws tus nqi qis, tus nqi siab, thiab kev ua haujlwm zoo. Txawm li cas los xij, nws kuj tseem muaj qhov tsis zoo, xws li hnav tsis zoo thiab corrosion kuj.

3. 40Cr cov khoom muaj kev ua tau zoo tag nrho tshaj li 45 steel, tab sis txhawm rau txhim kho nws cov corrosion kuj thiab hnav tsis kam, txheej ntawm chromium yuav tsum tau plated ntawm nws qhov chaw. Txawm li cas los xij, lub thickness ntawm chromium plating txheej muaj cov kev cai nruj, nws tsis tuaj yeem tuab dhau los yog nyias.
