↵Rail fishplate Fastening System
Railway Fishplate, tseem hu ua ib qho kev sib koom ua ke lossis splice bar, yog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau sib txuas tsim los koom nrog ob txoj kev tsheb ciav hlau xaus ua ke nyob rau hauv ib qho kev ruaj ntseg, zoo sib xws. Feem ntau yog tsim los ntawm qib siab -qib alloy steel los ntawm precision forging thiab machining txheej txheem, fishplates yog bolted los ntawm lub vev xaib ntawm kev sib txuas ntawm cov tsheb ciav hlau kom muaj kev txuas ntxiv, lub zog, thiab kev sib raug zoo ntawm txoj kev khiav. Lawv faib cov khoom thauj thoob plaws hauv kev sib koom ua ke, txo qhov sib txawv ntawm qhov sib txawv, thiab muab cov qauv tsim kev ncaj ncees thaum tso cai rau thermal expansion thiab contraction ntawm cov ntsia hlau.

Mechanical & Installation Perspective
Stress Distribution Geometry: Features tapered xaus thiab contoured profiles uas maj mam hloov khoov lub sij hawm thiab shear rog ntawm rail seem
Fatigue Resistance Design: Muab cov kab hluav taws xob sib txuas thiab kev hloov pauv kom tshem tawm cov kev ntxhov siab uas tuaj yeem pib tawg
Thermal Gap Management: Precision-machined ntsia liaj qhov rooj qhov tso cai tswj longitudinal txav thaum tuav kev ruaj ntseg transverse
Installation, Maintenance & System Integration Perspective
- Micro{0}}Alloyed Steel Composition: Siv vanadium-titanium txhim kho qib steel (piv txwv li, R260, 60CrMoB) nrog cov khoom muaj zog tshaj 650 MPa
- Isothermal Forging txheej txheem: Precision kaw- tuag forging ntawm kev tswj qhov kub thiab txias kom ntseeg tau tias cov qauv zoo sib xws thiab cov kev taw qhia lub zog
- Surface Enhancement Treatment: Txhaj peening ua raws li kev ntxhov siab nyem tsim compressive nto txheej txhim kho lub neej qaug zog los ntawm 40-50%
