After the roller is subjected to primary quenching, the roller is conveyed to the opposite side of the turnover piece 8, the pushing cylinder 821 drives the turnover plate 82 to approach to a quenched workpiece, the double-head cylinder 832 drives the two clamping jaws 933 to clamp the workpiece, the lifting cylinder 85 at the bottom jacks up the turnover plate 82, the workpiece is separated from the placing table 64 at the moment, the rotary cylinder 84 drives the workpiece to rotate after the clamping jaws 933 clamp the workpiece, and after the turning, the lifting cylinder 85 descends to enable the workpiece to be placed on the placing table 64 again for secondary quenching.
