Forged Steel, Alloy Steel & Cam khwb cia hlau Crankshafts: Qhov txawv qhov tseem ceeb & Vim li cas qhov zoo yog qhov tseem ceeb rau Crankshafts loj

Ua los ntawm siab- zoo alloy steel billets raug kub forging. The forging process aligns the metal grain flow with the crankshaft's stress directions, significantly enhancing material density, fatigue strength, and impact toughness. Forged steel crankshafts muaj lub zog tshwj xeeb thiab ua haujlwm ntev, muaj peev xwm tiv taus qhov sib txawv ntawm qhov hnyav thiab siab combustion siab ntawm hnyav- lub luag haujlwm cav (piv txwv li, hauv kev tsim kho tshuab, nkoj nkoj, cov tshuab hluav taws xob loj). Rau cov crankshafts loj, qhov txiaj ntsig zoo ntawm qhov no yog qhov ua kom muaj sia nyob ntev -lub sijhawm, kev ua haujlwm ruaj khov ntawm lub cav.

Feem ntau xa mus rau crankshafts ua los ntawm steel melted nrog cov ntsiab lus alloying (xws li, chromium, molybdenum, nickel). Lawv qhov kev ua tau zoo zaum ntawm forged steel thiab cam khwb cia hlau. Kev kho cua sov tuaj yeem txhim kho cov khoom, tab sis qhov sib xws ntawm sab hauv thiab qaug zog tsis kam ntawm cov qauv hlau hauv nws li - nrum lossis machined lub xeev feem ntau qis dua rau cov khoom siv forged.

Feem ntau yog ua los ntawm ductile (nodular) hlau. Qhov zoo muaj xws li kev castability zoo, tus nqi qis, thiab cov yam ntxwv zoo damping, ua rau lawv haum rau nruab nrab - mus rau - tsis tshua muaj roj av cav lossis diesel cav me me. Txawm li cas los xij, lawv lub zog, tawv, thiab kev cuam tshuam tsis zoo yog qis dua cov hlau forged, ua rau muaj kev sib tw rau kev ntseeg tau thiab kev ua haujlwm ntev nyob rau hauv cov xwm txheej hnyav ntawm hnyav-lub luag haujlwm, siab- tso zis cav.

Crankshafts rau cov cav loj hauv hiav txwv, cov khoom siv mining, thiab lwm yam, yuav tsum tuav lub zog ntawm ntau txhiab mus rau kaum txhiab horsepower. Tsuas yog cov hlau forged nrog cov khoom zoo heev ntawm cov khoom siv kho mob yog nyob ntawm txoj haujlwm.

Tshaj li ntau pua lab lub voj voog, lub crankshaft ua rau khoov thiab torsional qaug zog. The dense, fibrous grain structure of forged steel provides the best defense against the initiation and propagation of fatigue cracks.

Lub siab - zoo crankshaft loj tiv thaiv lub sij hawm poob loj thiab kho cov nqi cuam tshuam nrog kev ua tsis tiav, ua rau nws tseem ceeb rau kev tswj tag nrho cov nqi ntawm lub neej. Piv txwv li, kev ntseeg ntawm aKOMATSU 12V 140 Crankshafttsim los rau cov tshuab siv loj loj cuam tshuam ncaj qha rau cov cuab yeej muaj thiab muaj txiaj ntsig.

Siv ntau- txhiab-tuj nias rau kev tuag forging kom ua tiav cov hlau nplej ntws, tso lub hauv paus rau lub zog sab hauv thiab tawv.

Ua haujlwm siab - CNC tshuab rau milling, tig, drilling, thiab sib tsoo, nruj me ntsis tswj qhov ntev ntawm phau ntawv, roundness, concentricity, thiab nto tiav.

Cov txheej txheem zoo li quenching thiab tempering, nitriding, los yog induction hardening impart huab hardness rau hnav tsis kam thaum tuav lub hauv paus tawv kom tiv taus qhov cuam tshuam.

Siv ultrasonic thiab sib nqus particle kuaj los kuaj xyuas qhov tsis xws luag sab hauv thiab saum npoo, thiab xa mus rau Coordinate Measuring Machines (CMM) rau qhov tseeb geometric tseeb.
