- Abstract
The multi-direction forging process of railway clamp based on certain kind of preformed billet was designed. The railway clamp sample was acquired by industrial experiment. The causes of burr and other defects have been analyzed in multi-direction forging of railway clamp. The multi-direction forging process of railway clamp is simulated with DEFORM-3D software.Finite element analysis is developed to research the metal flow rule in forming process combined with the point tracing function in Deform. The result indicates that rough burr of railway clamp was mainly caused by the unreasonable design of experiment die structure. Forming load exceeds the capacity of the equipment, so the die is clamped badly. The critical reduction causing folding is 14mm. 9mm reduction will not result in folding. The solution was proposed after the analysis of forging defects of railway clamp preformed billet and well-formed samples were got, which verified the rationality of preformed billet shape and feasibility of forming process.
