Keeb kwm thiab technology ntawm shovel

Txhua tus yuav tsum tau pom duav. Lub shovel yog cov cuab yeej tsim khoom uas tau siv dav hauv kev tsim khoom thiab lub neej, thiab nws tseem dhau los ua lub tais hlau ntawm qee pawg niche niaj hnub no.
Nyob rau hauv cov nqe lus ntawm traceability, nws yuav tsum tau taug qab mus rau lub hnub nyoog pob zeb. Lub sijhawm ntawd, nws tau ua pob zeb thiab siv los ua liaj ua teb. Cov txheej txheem tsim khoom tshwj xeeb tsis tuaj yeem tshawb xyuas ntxiv lawm.
Peb tuaj yeem tham txog qhov tseem ceeb ntawm lub duav rau lub neej nyob rau xyoo 1980 thiab 1990s. Thaum ntawd, txhua tsev neeg yuav muaj duav. Txawm tias muaj pes tsawg daim av uas koj tsev neeg muaj, ntxiv rau plowing nyuj, nws yuav plowing los ntawm tib neeg. Nyuj plowing kuj yog ib yam khoom siv rau cov tswv tsev thiab cov neeg tua neeg hauv zos. Yog li seb kuv tuaj yeem noj thaum lub sijhawm ntawd puas yog nyob ntawm nws.
Tam sim no, daim ntawv thov shovel hauv lub neej tseem muaj, tab sis lub koob meej thiab kev vam meej ntawm lub xyoo tsis muaj lawm. Kev lag luam kuj maj mam tuag. Niaj hnub no, nrog rau kev xav nostalgic, kuv yuav muab rau koj ib tug nrov science ntawm zus tau tej cov shovels.
• cuam tshuam cov khoom
Ua ntej ntawm tag nrho cov, lub duav xav tau ib tug tej yam hardness thiab rigidity txiav steel, thiab cov txheej txheem txiav yog gas txiav.
Cov offcuts raug txiav ua ntej, thiab tom qab ntawd cov hlau raug txiav rau hauv qhov sib npaug.
Kuv xav siv lub sijhawm no los muab rau koj lub hauv paus ntsiab lus ntawm kev siv hluav taws xob nrov nrov: kev txiav roj yog hais txog kev siv cov nplaim hluav taws kub hnyiab rau cov hlau kom raug txiav mus rau qhov hluav taws kub, ua rau nws kub hnyiab hauv cov pa ntshiab huv, tsim. slag thiab tso cua sov ntau. Nyob rau hauv qhov kev txiav txim ntawm lub tshuab quab yuam, lub oxidized slag yog cua tshuab: lub tshav kub tso tawm ntxiv preheats cov txheej tom ntej ntawm cov hlau kom ncav cuag lub melting point. Cov txheej txheem hlau hlau txiav yog cov txheej txheem txuas ntxiv ntawm preheating, combustion, thiab slag tshuab. Nws cov ntsiab lus yog cov txheej txheem ntawm hlawv hlau hauv cov pa ntshiab, tsis yog txheej txheem melting.
• Kub dov
Ua ntej, cov hlau yog rhuab, thiab kub tswj ntawm 1000 ~ 1200. Lub austenite crystallization tsuas yog tsim tau thaum qhov kub siab tshaj ntawm A3 kab, yog li nws yuav tsum tau rhuab mus rau qhov kub thiab txias.
Cov txheej txheem cua sov yog qeeb heev, yuav tsum tau ua siab ntev tos. Tom qab cua sov tiav, cov hlau yog thawj forged.
Lub tshuab forging forges cov hlau nyuaj, uas yuav ua rau cov qauv thiab kev ua haujlwm ntawm cov hlau zoo ib yam. Tom qab forging tiav, nws los txog rau qhov txuas txuas.
Txhawm rau muab nws bluntly, nws yog maj mam kho qhov sib txawv ntawm cov chais kom cov hlau dov rau hauv cov ntawv nyias. Qhov chaw ua haujlwm zoo li no kuj txaus ntshai heev, thiab nws tsis yooj yim rau cov neeg ua haujlwm. Tom qab dov mus rau ib qho thickness, nws yuav tsum tau zoo-nias los ntawm ib txheej ntawm rollers.
Cov txheej txheem ntawm cov menyuam no belongs rau precision nias, uas ua rau lub thickness ntawm steel sawb tsis sib xws. Nyob rau hauv no txoj kev, zus tau tej cov steel sawb los mus rau qhov kawg.
• Npuag, sib sau
Lub tiav steel sawb yuav tsum mus los ntawm thawj txheej txheem - pwm blanking.
Los ntawm cov lus qhia ntxaws ntxaws ntawm tus kws tshaj lij, cov pwm sib thooj yog tsim los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Xws li cov pwm yog qhov yooj yim heev, thiab cov sawb yog xuas nrig ntaus rau hauv cov qauv coj los ntawm lub siab xa los ntawm lub tshuab xuas nrig ntaus. Cov pwm no yog cov pwm tawm hauv qab. Tom qab xuas nrig ntaus tiav, daim ntawv yuav tsum tau punched yooj yim.
Nws kuj yog qhov yooj yim heev kom rov qhib pwm. Tom qab lub punching tiav, lub billet yuav tsum tau rhuab.
Tom qab cua sov, lub billet yuav tsum tau zoo li tam sim ntawd.
