↵Rail Screw Spike Fastening System
Lub Rail Screw Spike yog threaded mechanical fastener engineered for securing rails to wood sleepers (ties) los ntawm qhov zoo, threaded kev koom tes. Tus cwj pwm los ntawm ntxhib- xov shank thiab lub taub hau loj, square lossis hexagonal, nws raug ntsia los ntawm kev ntsia hlau rau hauv lub pre-drilled pilot qhov nyob rau hauv lub pw tsaug zog.
Technical Specifications:

| Installation Ceev | qeeb.Yuav tsum tau drilling / piloting thiab wrenching. | Ceev dua.Direct rauj tsav tsheb. | ||
| Skill & Tool Requirement | Siab dua.Yuav tsum tau xyaum, torque ciaj ntswj, ntau yam txuj ci. | qis.Rauj, ntsuas, kev txawj ntse. | ||
| Tus nqi pib | Siab dua(tus nqi nce siab + ntau zog / sijhawm). | Tsawg heev. |
Functional & Engineering Perspective
High Uplift & Creep Resistance:Lub threaded shank muab ib tug zoo mechanical tuav nyob rau hauv lub sleeper, muab superior tiv thaiv rau lub ntsug "prying" rog ntawm nkhaus thiab qib, thiab mus rau longitudinal rail txav.
Ntoo Sleeper Preservation:Los ntawm kev txiav cov xov rau hauv ntoo es tsis yog wedging thiab splitting fibers, nws tsim ib tug huv si, muaj zog tuav nrog tsawg dua ntev - lub sij hawm kev puas tsuaj rau cov pw tsaug zog, muaj peev xwm ncua lub neej pw tsaug zog.
Daim ntawv thov qhov chaw tseem ceeb:Qhia tshwj xeeb rau thaj chaw muaj kev ntxhov siab siab, xws li kev nkhaus nruj, hloov cov ntsiab lus, kev sib koom ua ke ntawm kev tsheb nqaj hlau, cov ntoo choj, thiab cov qib hnyav - cov ntu uas tus qauv spikes yog qhov yooj yim rau xoob.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Khoom siv & Forging:Feem ntau ua los ntawm nruab nrab- carbon steel (xws li AISI/SAE 1035-1050) los yog boron- alloyed steel rau lub zog. Lub qhov khoob yog kub-forged los ua lub taub hau thiab shank, kom ntseeg tau tias muaj zog nplej txaus.
- Xov Rolling:Cov xov yog tsim tsis yog los ntawm kev txiav tab sis los ntawm txias - dov nyob rau hauv siab. Qhov kev ua haujlwm no- ua kom lub ntsej muag tawv tawv, txhim kho kev qaug zog, thiab tsim kom muaj cov xov zoo nkauj uas yooj yim rau kev tsav mus rau hauv ntoo.
- Kev kho cua sov:Ntau cov ntsia hlau spikes undergo quenching thiab tempering kom ua tiav lub xeev tawv, hardened (feem ntau rau Rockwell C 25-35), ntsuas qhov hardness xav tau rau cov xov nrog lub toughness los tiv thaiv poob siab thaum lub installation.
