متن کاملApplication of the Finite Element Method In Cold Forging Processes
The demand for more efficient manufacturing processes has been increasing in the last few years. The cold forging process is presented as a possible solution, because it allows the production of parts with a good surface finish and with good mechanical properties. Nevertheless, the cold forming sequence design is very empirical and it is based on the designer experience. The computational model...
متن کاملOptimization of Flash, Billet Dimensions and Friction Factor in Closed Die Cold Forging Process
Three important parameters in designing a closed die for forging process are ratio of width to flash thickness, ratio of height to billet diameter and the friction factor. In this paper the influences of these parameters on the required force for the forging and percentage of die filling were investigated. It was found that by controlling the flash dimension, the material loss is reduced and t...
متن کاملPrediction of Residual Stresses for a Hollow Product in Cold Radial Forging Process
Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axles and also for creating internal profiles such as rifling the gun barrels. The radial forging of tube is usually performed over a mandrel to create an internal profile and/or size the internal diameter. Most of the previous studies conducted on the radial forging process have u...
متن کاملNumerical and Experimental Investigation of Cold orBital Forging of a 16MnCr5 Alloy Spur Bevel Gear
The purpose of this research is to analyze the forging of bevel gears based on conventional forging method with material number 1.7131 with finite element method by means of SUPER FORGE software and to compare it with experimental cold orbital forging results.After doing simulation of conventional forging and obtaining press tonnage due to orbital forging method with DEFORM software, orbital fo...
