RailNtsia Hlau Spike Fastening System
Lub Rail Screw Spike yog qhov tseeb -engineered, externally threaded fastener tsim los ntawm siab- tensile steel, tsim los xa cov complex dynamic loads los ntawm txoj kev tsheb ciav hlau mus rau hauv lub hauv paus pw tsaug zog los ntawm mechanical interlock es tsis muaj kev sib txhuam ib leeg. Nws cov xov txuas txuas ntxiv hloov pauv siv lub zog sib hloov mus rau hauv kev tswj hwm, elastic clamping quab yuam uas ruaj khov lub hauv paus kev tsheb nqaj hlau lossis khi phaj thaum ua kom haum rau lub ntuj nthuav dav, kev cog lus, thiab kev sib haum xeeb ntawm cov ntoo tsaug zog ntau xyoo dhau los ntawm kev pabcuam hauv kev hloov pauv huab cua.
Technical Specifications:
| Parameter | Standard Duty Timber Spike | Premium Heavy Haul Spike |
|---|---|---|
| Txoj kev tsim khoom | Kub forged nrog txiav threads | chim siab forged nrog dov threads |
| Xov Profile | Tib - txhuas, 60℃flank lub kaum sab xis | Dual -kev xaiv ua, optimized flank geometry |
| Khoom Specification | Nruab nrab carbon steel (C 0.35-0.45%) | Micro{0}} alloyed steel (Cr, Mo ntxiv) |
| Kev kho saum npoo | Plain oiled los yog lub teeb zinc txheej | Kub-dip galvanized + organic topcoat |
| Kev xeem zoo | Dimensional thiab pom kev soj ntsuam | MPI + Charpy impact + tensile verification |
Installation & Maintenance Perspective:
- Progressive Thread Engagement:Daim ntawv tapered xov nyob rau hauv lub ntsis tso cai rau gradual load hloov los ntawm cov thawj koom xov mus rau cov xov tom ntej, tiv thaiv lub zos kev nyuaj siab concentrations uas yuav ua rau cov ntoo fiber ntau crushing los yog dowel tsis ua hauj lwm.
- Flank Angle Optimization:Cov xov profile nta ua tib zoo suav lub kaum sab xis (feem ntau 60-90 degrees) uas ua kom zoo dua qhov sib npaug ntawm kev tshem tawm thiab kev teeb tsa torque, kom ntseeg tau tias muaj zog hloov pauv thaum tsav tsheb.
- Root Radius Tsim:Cov hauv paus hniav yog qhov tseeb- dov nrog lub vojvoog dav dav es tsis yog cov kaum ntse ntse, uas txo cov kev ntxhov siab thiab txhim kho lub neej qaug zog los ntawm kev faib lub sijhawm khoov hla qhov dav dav - ntu ntu .
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Nruam Grain Flow Forging:Hwm spikes yog tsim los ntawm kev chim siab forging uas tswj tsis muaj kev cuam tshuam cov nplej ntws raws lub shank thiab mus rau hauv lub taub hau, khaws cia cov hlau lub ntuj fibrous qauv rau siab tshaj plaws lub zog.
- Xov Rolling vs. Txiav:Cov xov no feem ntau yog tsim los ntawm txias dov es tsis txhob txiav, uas ua haujlwm - hardens cov khoom thiab induces compressive residual stresses uas nquag tawm tsam qaug zog tawg pib .
- Chemical Composition Control:Hlau chemistry yog tswj tau meej nrog cov pa sib npaug tshwj xeeb thiab micro- alloying cov ntsiab lus (chromium, molybdenum) kom ua tiav los ntawm - cov yam ntxwv hardening yam tsis muaj kev txi core toughness .
