Rail Fishplate Fastening System
Railway Fishplate yog ib qho kev sib koom ua ke steel bar sib dhos thoob plaws lub vev xaib ntawm kev sib txuas ntawm kev tsheb ciav hlau xaus los ua ib qho kev sib koom ua ke uas tswj kev taug kev txuas ntxiv ntawm txhua qhov kev tsheb ciav hlau tsis sib xws. Qhov no precision -engineered Cheebtsam ua hauj lwm raws li ib tug load -hloov interface-thaum lub tsheb ciav hlau log hla qhov sib txawv, lub phaj ntses absorbs ntsug shear rog, resists kab rov tav dabtsi yog khoov lub sij hawm, thiab khaws cia lateral kev sib raug zoo thaum uas tso cai rau thermal expansion los ntawm qhov sib txawv tsim.
Technical Specifications:

Installation & Maintenance Perspective:
- Shear Force Hloov Mechanism:Vertical log loads tsim shear rog ntawm txoj kev tsheb ciav hlau kawg interface, uas cov ntses phaj kis thoob plaws qhov sib txawv los ntawm bolt clamping thiab kev sib txhuam, tiv thaiv qhov sib txawv ntsug txav uas yuav tsim kom poob rau hauv qhov chaw khiav.
- Lub Sijhawm -Kev Tiv Thaiv Kev Sib Koom Tes:Lub phaj phaj qhov tob (feem ntau yog 70-90% ntawm kev tsheb nqaj hlau qhov siab) tsim ib qho tseem ceeb seem modulus uas tiv thaiv lub sijhawm khoov, tuav txoj kev tsheb ciav hlau kawg hauv qab eccentric log loading.
- Tension-Compression Force Couple:Thaum lub sij hawm lub log, cov phaj phaj ua rau muaj kev ntxhov siab thaum lub phaj trailing raug compression - qhov kev sib tw quab yuam no tsim ib tus kheej - qhov chaw ua haujlwm uas tswj kev sib koom ua ke .
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Siab -Lub zog qis- Alloy Steels:Cov ntses niaj hnub siv HSLA qib nrog cov ntsiab lus microalloying (vanadium, niobium) uas ua tiav 550-700 MPa yield zog los ntawm cov nplej refinement es tsis yog cov ntsiab lus carbon ntxiv.
- Tswj Rolling xyaum:Thermomechanical dov ntawm 850-950℃refines ferrite grain loj rau ASTM 10-12, txhim kho ob qho tib si lub zog thiab toughness ib txhij yam tsis muaj kev kho cua sov tom qab.
- Los ntawm -Hardening Requirements:Bolt qhov cheeb tsam xav tau cov tawv tawv ntawm 260-320 HB los tiv thaiv lub qhov elongation nyob rau hauv cyclic bearing kev nyuaj siab, ua tiav los ntawm induction hardening los yog quench-thiab-temper processing .
