Plate spring double-end spring eye rolling line center hole positioning system

The invention discloses a plate spring double-end spring eye rolling line center hole positioning system. The system comprises a base, a supporting base, a conveying chain, a material supporting device, a turnover device, a centering positioning device, an intermediate-frequency heating furnace, a material blocking device, a double-end material cutting station, a double-end spring eye rolling station, a second center hole positioning pin, a first center hole positioning pin, a stand column, a supporting frame, a positioning material moving mechanical hand, a rolling station feeding mechanical hand and a transverse moving discharging mechanical hand. When a single steel plate spring is produced, discharging operation is conducted in a furnace opening, edge cutting and spring eye rolling of the two ends of the plate spring are positioned and produced by a plate spring center hole, and the situation that the processing position in the length direction of the plate spring is accurate is ensured. All positioning a
