Finite Element Forging Process Analysis of Bicycle Derailleur Hook of Aluminum Alloy

Abstract
Applying forging to produce automobile parts is a common technology, which can reduce material and time costs and increase product strength. Therefore, the forging process and die design of aluminum alloys have become very important in the production of bicycle parts.Due to the complexity of the forging process and die design, finite element analysis is used to help prevent forging defects during the forming process. This paper studies the forging of bicycle aluminum alloy pedals, the parting line, draft angle, forging tolerance, die fillet radius and flash are considered in the design of forging die. The finite element analysis of metal forming is used to simulate the forging process of bicycle pedals of aluminum alloy. Then the obtained forging load, stress distribution, temperature distribution, folding and underfilling determine the appropriate forging machine, die design and process parameters.Finally, a forging die is made to forge aluminum alloy bicycle pedals with good dimensional accuracy and high quality.
