“…Tube spinning can be divided into forward and backward spinning, depending on the relative directions of roller feed and material flow. 1,2 For forward tube spinning, material flows in the same direction as that of roller feed, with advantages including good fittability, high wall thickness reduction, small build-up and bulging. But blank length of this method is restricted by slide stroke and mandrel length.…”

“…Tube spinning process has been studied by several researchers. Fazeli and Ghoreishi, 2,3 Haghshenas et al 4 and Yao and Makoto 5 analyzed the effects of key process parameters on surface roughness, wall thickness variation and internal diameter growth based on experimental data. Jahazi and Ebrahimi, 6 Murata et al, 7 Su et al 8 and Kuboki et al 9 carried out experiments to investigate the effects of temperature and initial thickness deviation on roller force, spinning feasibility and elimination of spinning defects.…”

In this article, a unique phenomenon called position and inclination interference in stagger spinning process is characterized and investigated. A series of trials are presented to illustrate the causality of visible bulge and concave of wall thickness between position interference, as well as the imbalance and oscillation of roller force. Also, effects of inclination interference have been discussed. Finally, formulae of roller interval selection without interference phenomenon are derived based on the characteristics of position and inclination interference to help exclude invalid combination of roller intervals and guide selection of inclination of roller and blank, which will effectively reduce the amounts of invalid experiments or simulations.

“…The accuracy of flow formed shell largely depends on the selection of process parameters. Several studies [34][35][36][37] have been carried out in the past to identify the role of those settings on the accuracy of the flow formed products. Need for considering these parameters has been briefed below.…”

“…Further, they have observed an increase in diameter growth with an increase in thickness reduction. Some researchers [37] concluded that better surface finish in Aluminum 2024 tubes is obtained due to higher percentage of thickness reduction, increase in solution and ageing treatment time, less feed rate and minor speed of the mandrel.…”

Flow forming of thin-walled precision shells

Flow forming is an innovative form of cold and chipless metal forming process, used for the production of high precision, thin-walled, net-shaped cylindrical components. During this process, the length of a thick walled tube, commonly known as a preform, is increased with a simultaneous decrease in the thickness of the preform without any change in the internal diameter. Forming of the preform is carried out with the help of one or more rollers over a rotating mandrel. By a predetermined amount of thickness reduction in one or more number of forming passes, the work material is plastically deformed in the radial direction by compression and made to flow in an axial direction. The desired geometry of the workpiece is achieved when the outer diameter and the wall of the preform are decreased, and the available material volume is forced to flow longitudinally over the mandrel. Over the last three and a half decades the flow forming technology has undergone several remarkable advancements. The versatility of the process makes it possible to produce a wide variety of axisymmetric, nearer to the net-shape tubular parts with a complex profile using minimum tooling changes. In this review article, process details of flow forming have been elaborated. The current state-of-the-art process has been described, and future developments regarding research and industrial applications are also reviewed.

“…Surface quality (Fazeli and Ghoreishi, 2009), specific materials (Xu et al, 2005), and the geometric parameters (Fazeli and Ghoreishi, 2011) in the metal spinning process have been investigated using experiments and statistical principles. Experimental methods have high costs, restrictive conditions, detection limits, and many significant issues in the forming process.…”

Abstract:A modified 3D finite element (3D-FE) model is developed under the FE software environment of LS-DYNA based on characteristics of stagger spinning process and actual production conditions. Several important characteristics of the model are proposed, including full model, hexahedral element, speed boundary mode, full simulation, double-precision mode, and no-interference. Modeling procedures and key technologies are compared and summarized: speed mode is superior to displacement mode in simulation accuracy and stability; time truncation is an undesirable option for analysis of the distribution trend of time-history parameters to guarantee that the data has reached the stable state; double-precision mode is more suitable for stagger spinning simulation, as truncation error has obvious effects on the accuracy of results; interference phenomenon can lead to obvious oscillation and mutation simulation results and influence the reliability of simulation significantly. Then, based on the modified model, some improvements of current reported results of roller intervals have been made, which lead to higher accuracy and reliability in the simulation.
