Introduction to the production process of spring bars used in high-speed rail, subway, city rail and other railways

Introduction to the production process of Railway clips or spring bars used in high-speed rail, subway, city rail and other railways


Railway clips/Spring bar: through bending and distortion, the buckle force is generated on the track, which effectively guarantees the reliable connection between the rails for a long time, maintains the integrity of the track as much as possible, prevents the rail from moving in the vertical and horizontal directions relative to the sleeper, and ensures the normal gauge , So as to ensure the safety of rail vehicles.

The raw material of our railway spring bars is round steel (φ 13mm), and the purchased round steel is subject to the quality inspection standard after being inspected before entering the factory. The raw materials are sent to the hydraulic cutting machine for cutting, and the products are finally cut into different lengths, all controlled within 430mm. Then use a hydraulic round bar flat head chamfering machine to chamfer both ends of the round steel. After operation, the raw materials are sent to induction heating equipment for heating, and heated to 1050°C (using electric heating, no particles are produced), and the heating time is about 10 seconds. The heated material is sent to the press, and then bent up and down through the mold (three times of stamping is required), and finally the elastic product is formed. After stamping and forming, the workpiece with the required shape enters the quenching tank through the mesh belt for quenching, the quenching temperature is 800°C, and the quenching time is 10 minutes. After quenching, the workpiece is naturally cooled. After cooling, the workpiece enters the tempering furnace for tempering. Tempering mainly improves the strength, plasticity and toughness of the product, and the time is 90 minutes. After tempering, due to the high temperature of the workpiece, in order to facilitate the packaging of the workpiece, it is necessary to cool the workpiece and directly use water for cooling. After tempering and cooling, the product is coated with anti-rust liquid. After inspection, it is the finished product.
