Analysis and Optimization of the Radial Forging Process for Manufacturing Gun Barrels.

摘要

The mechanics of radial forging of tubes with compound-angle dies was investigated using the Slab method of analysis. The effect of strain, strain rate and temperature on the flow stress of the deforming material was considered using numerical techniques. The analysis has been to develop a computer program. This computer program is capable of predicting the load, power, and stress distribution in radial forging of tubes. The comparison of computer predictions with experimental data indicates that the analysis is sufficiently accurate for engineering purposes. A finite-difference analysis for predicting the time-dependent temperature distributions in radial forging of tubes was developed. This part of the study utilizes the analysis of metal flow in the radial-forging process, developed earlier in Phase I of the program. The entire procedure for predicting temperatures has been computerized in order to facilitate its use in overall optimization of the process. (Author)
