Abstract EN
The plastic penetration condition and biting-in condition of a radial conical ring rolling process with a closed die structure on the top and bottom of driven roll, simplified as RCRRCDS, were established.
The reasonable value range of mandrel feed rate in rolling process was deduced.
A coupled thermomechanical 3D FE model of RCRRCDS process was established.
The changing laws of equivalent plastic strain (PEEQ) and temperature distributions with rolling time were investigated.
The effects of ring’s outer radius growth rate and rolls sizes on the uniformities of PEEQ and temperature distributions, average rolling force, and average rolling moment were studied.
The results indicate that the PEEQ at the inner layer and outer layer of rolled ring are larger than that at the middle layer of ring; the temperatures at the “obtuse angle zone” of ring’s cross-section are higher than those at “acute angle zone”; the temperature at the central part of ring is higher than that at the middle part of ring’s outer surfaces.
As the ring’s outer radius growth rate increases at its reasonable value ranges, the uniformities of PEEQ and temperature distributions increase.
Finally, the optimal values of the ring’s outer radius growth rate and rolls sizes were obtained.
