Water tank mold pressing plate machining production line based on robot automatic feeding and discharging

The invention provides a water tank molded board machining production line based on robot automatic feeding and discharging, and relates to the technical field of steel plate water tank production and machining. The water tank mold pressing plate machining production line based on robot automatic feeding and discharging comprises a first mechanical arm feeding and discharging device, a pre-calibration positioning table, a mold pressing device, a second mechanical feeding and discharging mechanism, a rear calibration positioning table and a cutting device, and the pre-calibration positioning table and the mold pressing device are adjacently arranged outside the first mechanical arm feeding and discharging device. The four corners of the to-be-machined steel plate can be prevented from being fractured and split through the thin film, the product yield is improved, the problem that the production efficiency of an existing hot-dip galvanized steel plate water tank is low is solved, automatic compression molding a
