“…There are many factors that affect the formation of bimetal tube spinning, such as process parameters, tube size, roller size, and material properties. This paper focuses on effect of key process parameters [21] in the spinning compound process including the press amount (ψ), the roller feed rate (v) and spindle revolutions(s) in the bimetal tube spinning forming. Through research, we found that the spindle speed changes have little effect on the deformation of the tube.…”

Tube spinning technology represents a process with high forming precision and good flexibility and is increasingly being used in the manufacture of bimetal composite tubular structures. In the present study, a forming analysis of clad tube and base tube in spinning process was conducted through numerical simulations and experiments. There was an equivalent stress transition on the interface since the stress transmission was retarded from clad tube to base tube. The yield strength became a main consideration during a design bimetal composite tube. Meanwhile, the strain distributions in axial direction, tangential direction, and radial direction were also investigated to determine the deformation characteristics of each component. As the press amount increased, the strain of clad tube changed more than base tube. As the feed rate increased, the strain decreased in axial direction and tangential direction but almost unchanged in radial direction. Simultaneously, a method for controlling the wall thickness of the clad tube and the base tube is proposed. These results to guide the design of bimetal tube composite spinning process have the certain meanings.

“…Additionally, attempts to produce axisymmetric and asymmetric components by the spinning process without a mandrel have been reported in some papers. Jia et al (2015) studied the effects of process parameters, including roller feed rate, nose radius, roller path, and half-core angle, on the surface quality of specimen in the square-section die-less spinning process. They also modeled Al 6061 blank as a deformable 3D solid.…”

Sheet metal Spinning process Feed rate Mandrel rotational speed Stress and strain Wrinkling. Many equipment and devices utilized in the aerospace industry are formed as symmetric parts through high plastic deformation of high strength sheet metal alloys with low thickness. Considering the inherent advantages of the spinning process of simple tooling and concentrated deformation loading, this process can be considered as one of the main options in producing these thin-sectioned lightweight parts. In this study, a Finite Element (FE) model has been developed to simulate the formation of a stepped thin-walled cylindrical workpiece of AISI 316 stainless steel alloy by spinning process. The FE simulation results were employed to investigate the effects of process parameters, including feed rate of the roller and rotational velocity of the mandrel on the distribution of stress and strain in the sheet metal, wrinkling failure, and thinning of the sheet metal during deformation. Experiments were carried out using selective input parameters based on the results of FE simulations. The comparison between FE simulations and experiments revealed that the developed model could predict the thinning of the sheet metals with over 93 % accuracy. Additionally, a good agreement between the experimentally deformed sheet configurations with those resulting from finite element simulations has been observed.

Several researchers have developed various spinning methods to produce non-circular hollow parts. In this paper, an approach that the rollers revolve around the roller principal axis was used to generate a concentric circular trajectory to the spinning trilateral workpiece. The spinning simulation was performed in ABAQUS 2016/Explicit software. The trajectory of the roller is derived, and the distributions of the equivalent von Mises stress, equivalent strain, wall thickness of the workpiece in typical section and spinning force are obtained. The simulation experiment proves the feasibility of using the proposed spinning method to produce workpieces with trilateral cross-section. The results demonstrated that after seven passes, in the area where the roller unloads the workpiece and the area where the roller starts the forward pass, local wrinkling may be generated; the most vulnerable area of the workpiece is also located at the area where the roller starts the forward pass, while the overall thinning rate of the workpiece is below 21%. Compared with other existent non-circular spinning methods, this novel method could process non-circular parts with a high rotational velocity, while ensuring the roller processing trajectory with high accuracy. The application of this method will improve the efficiency of the process by more than 200% in theory, while ensuring workpiece quality
