↵Rail Lub xub pwg Fastening System
A Railway Lub xub pwg nyomyog cov txheej txheem kev sib txuas ua ke uas ua haujlwm tseem ceeb ntawm kev thauj khoom - hloov chaw ntawm cov tsheb ciav hlau fastening systems thiab cov neeg pw tsaug zog lossis taug kev slabs. Engineered nrog cov geometric profiles meej, nws ua tau peb lub luag haujlwm tseem ceeb: xa cov ntsug / kab rov tav los ntawm kev tsheb nqaj hlau mus rau kev txhawb nqa cov qauv, tswj cov kev tsheb ciav hlau zoo ib yam (feem ntau 1: 40 inclination), thiab muab kev tuav cia rau sab nraud kom tswj kev ntsuas kev ncaj ncees. Tsim los ntawm siab - cov ntaub ntawv muaj zog los ntawm cov txheej txheem casting los yog forging, lub xub pwg nyom ua raws li lub hauv paus ntsiab lus uas ua rau cov elastic fasteners ua tau zoo nyob rau hauv lub tsheb ciav hlau dynamic loads.

Functional & Mechanical Perspective
Multi-Axial Load Transfer: Hloov cov clamping quab yuam rau hauv qhov ruaj khov siab faib thoob plaws qhov chaw pw tsaug zog thaum tiv thaiv kev tsheb nqaj hlau yob, kev txhawb nqa, thiab kev nkag mus ntev.
Geometric Control Element: Features lub kaum sab xis ntawm qhov chaw sib cuag (feem ntau yog 1:40) uas tuav txoj kev tsheb ciav hlau kom zoo rau lub log zoo- kev sib cuag thiab hnav cov qauv.
Gauge Preservation Mechanism: Sib txuas nrog rau sab nraud abutment ntsej muag uas lub cev txwv kev tsheb ciav hlau taw, ua tus thawj tiv thaiv kev ntsuas qhov dav.
Material & Manufacturing Perspective
- Ductile Hlau Dominance: Feem ntau lub xub pwg nyom siv spheroidal graphite hlau (EN-GJS-500-7)) kom pom kev sib npaug ntawm castability, lub zog, qaug zog tiv thaiv, thiab tus nqi-zoo.
- Precision Casting Requirements: Ua los ntawm cov xuab zeb-casting lossis peev txheej txheej txheem nrog nruj me ntsis kam rau ua (± 0.5mm feem ntau) rau kev sib koom ua ke.
- Surface Engineering: Feem ntau tau txais kev tiv thaiv zoo li epoxy coatings, galvanizing, los yog cov xim tshwj xeeb los tiv thaiv corrosion los ntawm ballast abrasion thiab ib puag ncig raug.
