The Mechanism of Forming Hollow Shafts with Constant Wall Thickness by Three-Roll Skew Rolling

Metals
To solve the problem of the long forming process for hollow shafts with constant wall thickness (HSCWT), a new process for forming HSCWT, namely three-roll skew rolling, has been proposed.

Microstructure evolution of three-roll skew-rolling formed hollow axles with uniform wall thickness.

The International Journal of Advanced Manufacturing Technology, 2022
Abstract The uniform thickness hollow axle is one of the lightest weight axles in the high-speed rail industry. It can effectively reduce unsprung mass and further improve the train speed. Therefore, due to its importance and significance, it is crucial to research and develop the uniform thickness hollow axle. To understand the microstructural

Design and technological capabilities of a CNC skew rolling mill [PDF]

Archives of Civil and Mechanical Engineering, 2021
Abstract Results of a study investigating a skew rolling process for elongated axisymmetric parts are presented. Despite the fact that the skew rolling technique for producing such parts was developed and implemented in the mid-twentieth century, there are no studies on this problem.

Research on variation law of workpiece temperature of three roll skew rolling hollow axle

IOP Conference Series: Materials Science and Engineering, 2022
To explore the variation law of workpiece temperature in the process of three roll skew rolling (TRSR) hollow axle, the process of TRSR hollow axle is tested and simulated in this paper. Firstly, the working principle of TRSR hollow axle is described; Then the blank and rolling process parameters are selected according to the actual performance of TRSR

Manufacturing large shafts by a novel flexible skew rolling process [PDF]

The International Journal of Advanced Manufacturing Technology, 2021
Abstract When manufacturing large shafts with multi-specification and small-batch production, both the conventional forging and rolling process bring a high tooling cost due to heavy forging press or large-size specialized roller. In this study, a novel flexible skew rolling (FSR) process is proposed by adding degrees of freedom to the rollers ...

The influence of the inter-particle sliding, rolling and torsion resistance on the skew-symmetric stress of sheared granular materials [PDF]

EPJ Web of Conferences
Granular materials are made of discrete particles that interact with each other through their contacts (forces and torques). On the example of a particle simulation of a Cartesian (planar) split-bottom shear cell, we show the effect of microscopic ...

Investigation of hot deformation behavior and three-roll skew rolling process for hollow stepped shaft of Al–Zn–Mg–Cu alloy

Journal of Materials Research and Technology
The increasing demand for high-strength lightweight hollow shafts in transportation highlights the need for advanced fabrication techniques. Al–Zn–Mg–Cu alloys, noted for their superior properties, are selected for three-roll skew rolling (TRSR). In TRSR,
