Description

technical field [0001] The invention relates to a radial-axial ring rolling experimental test device and an experimental test method, which are used for rolling small rings of soft metal materials in a room temperature environment to obtain axial rolling force, axial rolling moment and radial rolling force. Force and energy parameters such as rolling force and radial rolling moment create experimental conditions for the formulation of large-scale ring rolling process and theoretical research on ring rolling. Background technique [0002] Large-scale ring rolling is a plastic processing process that uses a radial-axial ring rolling machine to produce continuous local plastic deformation of the ring, thereby reducing wall thickness, expanding diameter, and forming cross-sectional contours. This process is suitable for producing annular mechanical parts of various shapes and sizes, such as bearing rings, ring gears, flanges, wheel hubs, thin-walled cylindrical parts, wind power...

AI Technical Summary

Problems solved by technology

[0003] The radial-axial ring rolling machine has a large volume and cannot directly obtain relevant force parameters. It can only be obtained indirectly through the pressure value of the hydraulic system of the equipment and the voltage value and current value of the motor.

Due to the interference of hydraulic leakage, friction and other factors, there will be large errors in the indirectly obtained parameters, which will bring many effects to the research work.

At the same time, the cost of experiments using radial-axial ring rolling machines is high, the experiments are difficult, and it is impossible to carry out a large number of experimental studies

There are few studies on radial-axial ring rolling, not only because the radial-axial ring rolling process is more complicated than radial ring rolling, but also the lack of experimental equipment is the biggest bottleneck restricting its in-depth research.
