Spring Clip technical requirements for cartridge production
2021-09-18
Spring Clip is under repeated alternating stress work,it has to withstand bending,torsion,fatigue and corrosion and other effects,in the vehicle to withstand a huge impact,so the requirements for elastic bar is very strict.
The rail is the part supporting the locomotive and the direction of the locomotive.The rail is fixed to the sleeper of the track bed by elastic fasteners.Elastic fasteners withhold article is mainly to play,it is calculated by the bending and twist deformation,buckle pressure effect on the orbit,effectively guarantee the reliable connection between rail for a long time,as far as possible to keep the integrity of the orbit and stop the rail lateral movement relative to the sleeper,ensure the normal track,to ensure the safety of the rail vehicle.In addition,because the contact between the train wheel and the rail is rigid contact,it is inevitable to produce vibration,and the special elastic structure makes it also has the absorption of the impact energy generated when the vehicle passes by,to achieve the role of shock absorption. Railway Stainless steel elastic Clip technical requirements 1.The material is 60Si2Mn or 55Si2Mn hot rolled spring round steel,and the technical requirements shall comply with the provisions of GB 1222. 2,Metal Spring Clips for Railway hardness of HRC41~46. 3.The metallographic structure of Spring Clip should be uniform tempered trostite and sorrotenite,and a small amount of intermittent ferrite is allowed in the heart. 4.Spring Clip shall not overheat or overburn.
