Rotary Forging of Hollow Components with Flanges

Abstract: This paper is about development and testing of cold rotary forging technology for manufacturing of hollow shaft flanges. Rotary forging mills with rotated die and conical roll were used for forming. Pre-machined blanks were made from pieces of welded or extruded pipes from carbon steel with 0.2 % of carbon. Design of tool-sets, sketches of blank and forged parts are presented.

“…forging, stamping. rolling) [5][6][7][8]10], we offer optimal energy-saving and material-improving modes for producing metal preforms under warm forging/stamping treatment from steel 40Cr and 20Cr13. Provided forging/stamping under optimum (warm treatment) mode and by standard factory mode (mentioned above), obtained data to compare mechanical properties and metal structure of the obtained metal examples.…”

“…Rotary forging is a special technology for the plastic working of a wide variety of mechanical components such as disks, rings, flanges, and gears. 1 3 It has many advantages over the conventional technologies, such as requiring lower load, being shockless and noiseless, and affording better working conditions. 4 , 5 A lot of studies on the rotary forging process have been carried out, such as the mechanism of material flow, 6 , 7 the influence of key process parameters on cold rotary forging, 8 , 9 and mushroom shape formation mechanism of the workpiece during rotary forging.…”

“…Now-a-days rotary forging has become a substitute for conventional forging especially in case of producing thin discs and large flanges having high diameter-to-thickness ratio. Reports by Semiatin [1] and Aksenov and Kunkin [3] indicate that approximately one-quarter to one-third of all parts that are either hammer or press forged could be formed on a rotary forge, however the rotary forge applications are limited to the production of only axisymmetric parts at present.…”
