Before the operation, firstly, the metal blanks 10 are stacked on the placing platform 51 one by one, and the push plate 57 extrudes the metal blanks 10, and then the operation is started; firstly, the first telescopic push rod 55 is operated, the first telescopic push rod 55 pushes the metal blank 10 facing the first through hole 521 to the conveying surface of the feeding conveying assembly 4 from the top surface of the placing platform 51, then the first telescopic push rod 55 retracts and resets, the second telescopic push rod 56 is operated to move the metal blank 10 on the placing platform 51 towards the first through hole 521 through the push plate 57, and make a metal blank 10 facing the first through hole 521, meanwhile, the conveying motor of the feeding conveying assembly 4 operates until the metal blank 10 on the conveying surface is conveyed to the upper side of the conveying surface of the feeding machine 3 to stop operating, then the feeding machine 3 conveys the metal blank 10 to the heating furnace 1, the metal blank 10 coming out of the discharging end of the heating furnace 1 vertically drops from the discharging hopper 6 to the containing barrel 75 positioned right below the discharging hopper 6, and then along with the operation of the discharging conveyer belt 74 to the end where the clamping assembly 8 is positioned, then stopping operation, driving a power part corresponding to the clamping assembly 8 to enable the clamping structure 84 to face the metal blank 10, then being clamped by the clamping structure 84, enabling the clamping structure 84 to face the working table of the oil press 9 through the vertical rotating motor 832, then driving the first sliding driving part 82 to operate, enabling the clamping structure 84 to operate towards the working table of the oil press 9, enabling the first sliding driving part 82 to stop operating when the metal blank 10 clamped by the clamping structure 84 is located right above the working table of the oil press 9, then driving the clamping rotating motor 842 to operate, enabling a clamping opening formed by the first clamping rod 844 and the second clamping rod 845 to be opened, enabling the metal blank 10 to be placed on the working table of the oil press 9, then enabling the clamping rotating motor 842 to stop operating, then driving the first sliding driving part 82 to operate reversely, enabling the clamping structure 84 to withdraw from the oil press 9, and returning to one end of the discharging conveyer belt 74 to finish single conveying, and finally driving the oil press 9 to operate.

It should be noted that, in the present invention, the automatic feeding device can make the interval at which the automatic feeding device conveys the metal blanks 10 match the conveying interval of the feeder 3 by controlling the time or mileage of a single operation of the conveying motor of the feeding conveying assembly 4, the first telescopic push rod 55 and the second telescopic push rod 56; in a similar way, the automatic discharging device can enable the whole production line to be connected by controlling the running time of the corresponding driving piece, and in addition, the sensor can be arranged to sense, and then the corresponding driving piece is driven to run to achieve the continuous running of the whole production line.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
