Finite Element Simulation And Analysis Of60AT Rail Heel-End Forging Process

With the railway development tow and high-speed railway and heavy-load freight, rail is gradually, replaced by heavy rail. The corresponding point of the tip rail should been produced by special section rail. The end piece60AT rail forging is the key processes affect the quality in manufacturing process of AT rail. Design on process and enforcement in this process direct impact on performance, quality and service life of the AT rail.In the production process of end piece60AT rail forging, charge in rail head, rail waist folding will be happen in one company. Detailed analysis of defects in the form of the end piece60AT rail forging, Include advantages and disadvantages of processing difficulties. Analysis through a series of simulation, use finite element numerical simulation software Deform to simulate the end piece60AT rail forging. Study on the temperature calculation of the billet, deformation of the workpiece resistance calculated, the reasons cause processing defects, and improve the design of the mold. Through the formation of defect simulation, for further optimization of the existing forging process provides basis.On the basis of the constitutive equation60AT switch rail materials, make the blank mold and solid modeling by two-dimensional drawing software AutoCAD. Make finite element simulation model of end piece60AT rail forging by Deform. Simulation of the forging process of end piece60AT rail forging. Been to work step deformation resistance has been the validation of the actual production of Petroleum presses load. It is suggested that the establishment of the forging simulation model can more accurately reflect the actual production in the forging process.The end piece60AT rail forging is a complicated forging process. With the simulation of forging process, metal flow pattern and the stress-strain distribution. Find out the rail head charge, the causes of rail waist folding defects. Simulation:optimization of the structural dimensions of the mold jaw rounded corners, and at the rounded corners and other parts of the rail waist to prevent forming defects generated; the blocker rail waist height, and can make the final forging process becomes simple.The subject of the end piece60AT rail forging has guiding significance., and can be used to guide production.
