Simulation of a hot forging Process for 42CrMo4 Connecting rod in application of reduction in Unfilling

Abstract

The objective of this paper is to find an optimum temperature range in which no unfilling is found in hot forging of connecting rod made of 42CrMo4. Connecting rod is one of the most important components in automobile. It is very helpful in machines where reciprocating motion is converted into rotary motion.The current rejection rate due to unfilling is 2.1 %. So, process parameters affecting Unfilling were identified. Other parameters affecting were also discussed in detail in So, in order to achieve the required objective of minimizing Unfilling, simulation of temperature at which billet is forged (the most affecting parameter for unfilling defect) is done using DEFORM 3D software, which is a powerful tool for analyzing material flow. The validation of the simulated range will be taken and experimented in the industry.
