Structure for prolonging service life of core roller of rolling machine

The utility model discloses a structure for prolonging the service life of a core roller of a rolling mill, which comprises a first retainer plate, a second retainer plate and a support plate, the first retainer plate and the second retainer plate are horizontally arranged on a workbench, the first retainer plate and the second retainer plate are oppositely arranged, and the support plate is arranged on the first retainer plate. The two ends of the supporting plate are fixed to the first retainer plate and the second retainer plate respectively, and the supporting plate enables the part, located below the workpiece, of the rolling core roller to abut against the direction where the rolling main roller is located. The supporting plate is designed to be a fulcrum in the middle of the rolling core roller, so that the stress state of the rolling core roller is changed, the rolling core roller of the same specification can bear larger rolling force, brittle failures caused by the fact that the rolling core roller
