Kev Cai Hlau Stamping Tuag; Nruam Stretching Tuag Rau Cov Khoom Siv Hauv Tsev

I. Cov yam ntxwv thiab cov kev sib tw ntawm High-Strength Steel Kub Stamping txheej txheem

Thaum lub sij hawm siab -lub zog steel kub stamping, cov khoom yuav tsum tau rhuab mus rau 900-950℃kom ncav cuag lub xeev yas, ua raws li cov cua txias ceev kom ntseeg tau tias cov khoom ua tau raws li cov qauv. Qhov kub thiab txias ceev txheej txheem yuav tuag mus rau ib tug zoo kawg nkaus tshav kub load. Yog hais tias lub tshav kub hloov efficiency ntawm lub cua txias yog tsis txaus, nws yuav ua tau rau lub zos overheating ntawm cov tuag, ua rau tawg thiab deformation, thiab ua rau qhov sib txawv ntawm qhov sib txawv ntawm cov khoom tiav. Tsis tas li ntawd, lub zog siab thiab hardness ntawm high-strength steel yuav tsum tau tuag kom muaj zoo heev hnav tsis kam thiab kub tsis kam; txwv tsis pub, teeb meem xws li kev tuag sai sai thiab tsis ua haujlwm yuav tshwm sim.

II. Txias txheej txheem optimization tswv yim

1. Rational Design of Cooling Channel Layout: Siv CAD software tsim thiab CFD simulation los ua kom zoo dua qhov kev teeb tsa thiab cov duab ntawm cov cua txias, kom ntseeg tau tias cov dej txias tsis sib xws tsis muaj qhov chaw tuag lossis thaj chaw ntawm cov cua sov sib xyaws . 1. Cov Cuab Yeej Cuab Yeej: Cov cua txias ua haujlwm siv cov serpentine lossis convex ntawm 1-2 mm ntawm {2} channel nrug ntawm 20-30mm. Lawv ua raws li cov pwm kab noj hniav saum npoo, tshuav 8-15 hli mus rau qhov chaw txias txias thiab txhim kho cov cua sov hloov mus los ntawm 25% -35%.

2. Ntau- ntu Txias Tswj: Cov ntsuas kub ntsuas tau teeb tsa hauv thaj chaw tseem ceeb xws li pwm kab noj hniav thiab txiav ntug los saib xyuas cov pwm kub hauv lub sijhawm, nrog rau qhov kub thiab txias tswj tsis pub dhau ± 5 degree. Multi- ntu zoned cua txias hloov kho yog siv, kho tus nqi dej txias (5-15L / min) raws li qhov ntsuas kub ntawm thaj chaw sib txawv. Qhov no tswj tau qhov kub thiab txias gradient, tsis txhob thermal stress concentration, thiab ncua cov pwm lub neej kev pab cuam ntau tshaj 30%.

3. Daim Ntawv Thov Kev Tshaj Tawm Tshiab Txias: Cov dej-raws li cov dej txias nrog cov nanoparticles ntxiv (xws li alumina thiab graphene) yog siv, ua kom cov cua sov hloov pauv los ntawm 15% -20%, ua kom txias ceev, thiab txhim kho cov cua txias sib xws. Qhov no ua kom tus nqi txias ntawm 20-30℃/ s rau cov hlau muaj zog, ua tau raws li qhov yuav tsum tau ua rau kev tsim cov khoom siv tshuab. Lub coolant yuav tsum tau raws li cov tshuaj stability ntawm cov khoom pwm kom tsis txhob corroding pwm nto. Lub coolant qib pH raug kuaj xyuas tsis tu ncua, thiab nws raug hloov tam sim ntawd. III.
