TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of hydraulic punching machines, in particular, relate to a galvanized bridge numerical control hydraulic punching machine and method. BACKGROUND

[0002] The galvanized bridge is a kind of metal bridge treated by galvanizing process on the basis of steel bridge, mainly used for cable management and wiring. The galvanized bridge has the characteristics of strong corrosion resistance, high structural strength and good ventilation performance, and is widely used in the fields of construction, industry and communication. The galvanized bridge needs to be fixedly connected with a support, a hanging bracket or a wall body during use. Therefore, after the production of the galvanized bridge is completed, the surface of the galvanized bridge needs to be punched by a numerical control hydraulic punching machine, so as to facilitate the subsequent connection of the bridge and the supporting structure by bolts, nuts and other connecting pieces.

[0003] When the galvanized bridge is punched by the hydraulic punching machine, the galvanized bridge is placed on the punching machine. The punching machine controls the servo second motor to drive the gear and rack through the numerical control system, and then drives the galvanized bridge to move forward to the lower end of the punching die. Then the hydraulic cylinder drives the punching die to move downward to punch the galvanized bridge.

[0004] During the punching process, although the galvanized bridge can automatically move forward under the driving of the punching machine, after the punching is completed, the staff needs to carry and take the punched galvanized bridge on the side of the punching machine, and take the galvanized bridge out of the discharge port, so as to facilitate the subsequent movement of the galvanized bridge. Therefore, manual collection and placement are still needed during material collection, which is troublesome. SUMMARY
