The invention discloses an after-shear workpiece retreating structure for a strengthening roller way. The after-shear workpiece retreating structure comprises a rack. The two ends of a flat roller shaft are fixed in bearings, and the bearings are fixed to the rack. A flat roller is fixed to the flat roller shaft. Strengthening structures are arranged at the portions, out of the rack, of the two ends of the flat roller shaft. Each strengthening structure comprises a cylindrical supporting body fixed to the flat roller shaft. A supporting ring is arranged outside each supporting body, wherein the outer side of the supporting body is in butt joint with the inner side of the supporting ring. The supporting rings are fixed to the outer side of the rack. A hydraulic oil cylinder is arranged on the rack. The piston end of the hydraulic oil cylinder is fixed to a push plate, and the push plate corresponds to the position of a workpiece. The after-shear workpiece retreating structure has the beneficial effects that the flat roller shaft is changed to be in a two-end supporting form, and therefore the strength is greatly improved in the stress process of the flat roller; the strengthening structures are added and are used for improving stress structures of the bearings, and the service life of the bearings is ensured; and a material push structure is added, and it is ensured that materials retreat in order.
