Description

Technical Field

[0001] The utility model relates to the technical field of pressing, in particular to a railway track spring bar forming device. Background Art

[0002] Rails are components that support locomotives and the direction of locomotives. Rails are fixed to the sleepers of the roadbed by elastic fasteners. The buckling parts of the elastic fasteners are mainly spring bars. The spring bars work under repeated alternating stresses. They are subjected to bending, torsion, fatigue and corrosion. When vehicles pass, they must also withstand extremely high instantaneous impact loads. Therefore, the performance requirements of the spring bars are very strict. The spring clip buckling parts mainly utilize the bending deformation properties of the material when working. The processing is relatively simple and the cost is often low. However, due to the holes opened for bolt fastening, stress concentration is prone to occur in this part. The maximum surface bending moment is exactly the maximum cross-section weakening point. Therefore, the stamping forming of the spring bar is very important. The forming of the spring bar is mainly through bending the heated and softened steel bar into a certain shape through a forming device. However, the traditional spring bar forming device cannot cool the formed steel bar in time, resulting in the heated and softened steel bar still having a certain elasticity. After it is taken out, it often rebounds and deforms, seriously affecting the quality of the spring bar. In addition, the normally formed spring bar requires a certain amount of cooling and extrusion, which wastes a lot of time. Therefore, a railway track spring bar forming device is proposed.
