“…The concept of using flow forming to create tubular parts with internal gearing elements was developed decades ago [6,7] and is applied today in the series production of plate carriers with internal gears for gearboxes in the automotive industry for example [8,9]. In the flow forming of tubes with inner ribs it is also common to use balls as rolling elements [10][11][12][13][14].…”

The motivation behind the development of a new approach to the manufacture of tailored tubes is the need for greater flexibility in the wall thickness variation of semi-finished parts compared with present manufacturing processes. In the so-called Internal Flow-Turning (IFT) process, the wall thickness contour of regular tubes with a uniform wall thickness is adjusted by means of a rolling process employing an innovative roller tool on the inside of the tube and a die on the outside of the tube. The gap between the roller element and the die can be adjusted through the axial infeed of the roller tool. The gap defines the current wall thickness of the tube during the manufacturing process. In this way, the wall thickness contour can be set in a precise manner by varying the gap distance as the tube is being pulled through the die. Besides the possibility of locally adjusting the wall thickness, IFT can also be used to form geometrical rib elements in the radial tube direction by using a radially shaped die. As the material flow in the IFT-process is mainly caused by compressive stress, the grooves of the die can be “filled up” by radial material displacement.

“…Jiang et al investigated the spinning process of thin-walled tubular part with longitudinal inner ribs. In their researches, multi-pass spinning and ball-shape roller were adopted, and the investigation results indicated that increasing the size of the ball contributed greatly to the stable flow of the metal as well as the formability of the inner ribs, but too large a ball led to the poor surface finish of the spun part; multipass spinning can guarantee the formability of the inner ribs [12,13]. Shimizu obtained the elliptical coneshaped products through synchronous spinning, but in his research, a mandrel with accordant shape was required [14].…”

In view of the importance of the surface quality in the application to the square section die-less spinning, the effects of several key parameters which include roller path, half-cone angle, and roller nose radius on the surface quality are investigated. Through the geometric model of residual height, the effect law of the roller path is obtained: the surface quality increases with the decrease of the axial distance of two adjacent slices. Then the finite element model of the square section die-less spinning is established, and the normal force and axial strain states in the deforming process are adopted to predict the relationship between the surface quality and the half-cone angle. Combined with the residual height model and finite element analysis, the roller nose radius' effect on the surface quality is also obtained. Enlargement of the two parameters can improve the surface quality. All the analysis results are verified by the surface waviness test of the specimens from the workpiece after spinning.

“…Tang et al (2007) performed an experimental study on oil-filled high-speed spin forming micro-groove fin-inside tubes and found that the thinning ratio of wall thickness, material plasticity, ratio of drawing to spinning, spinning speed and lubricating state are the main factors affecting the groove depth and surface roughness. Jiang (2007) stated that undesired inner rib is the common forming defect for ball spinning process of thin-walled tubular part with longitudinal inner rib, and in order to obtain desired inner rib, multi-pass spinning technology must be adopted (Jiang et al, 2009b). However, until now literature about the study on power spinning process of parts with transverse inner rib has been scant.…”
