[0030] Combined with the description of the above-mentioned material-dispensing mechanism, during operation, multiple metal plates are placed inside the storage box 3. In the initial state, the push rod 14 is in contact with one side of the plate at the bottom, and the switch of the dual-axis motor 5 is turned on. The dual-axis motor 5 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the two connecting arms 1 7 fixed thereto to rotate, and then the two connecting arms 2 8 rotate and move, making a circular reciprocating motion, and finally driving the movable plate 9 to move synchronously, and then the fixed rod 13 and the push rod 14 move, and the push rod 14 moves to press the plate. Push to move the plate at the lower end to the stamping position. As the two connecting arms 1 7 rotate, the two connecting arms 2 8 are driven to move back. At this time, under the action of the gravity of the plates inside the storage box 3, multiple plates press down the pushing rod 14, and the pushing rod 14 moves down along the inner side of the fixed rod 13, thereby ensuring the return stroke of the fixed rod 13 and the pushing rod 14. When the pushing rod 14 moves to the side of the material dispensing port 20, the elastic potential energy of the spring 141 resets the pushing rod 14. Similarly, continue to push the plate at the lower end.

[0031] like Figure 5 As shown, in one embodiment, the stamping mechanism includes a mounting frame 15 fixed to the upper side of the workbench 1 at one end, a hydraulic cylinder 16 is installed on the inner side of the mounting frame 15, a mounting shaft 17 is fixed to the telescopic end of the hydraulic cylinder 16, and a mold 18 is screwed to the lower end of the mounting shaft 17;

[0032] Combined with the description of the above-mentioned stamping mechanism, when the sheet is pushed to the stamping position by the material-dispensing mechanism, the switch of the hydraulic cylinder 16 is turned on to control its telescopic end to extend. The extension of the telescopic end of the hydraulic cylinder 16 drives the mounting shaft 17 and the mold 18 to move downward, stamping the sheet to form parts of specific shapes.

[0036] like Figure 1 As shown, in one embodiment, a collection box 23 is placed below the workbench 1 to facilitate the unified storage of stamped parts.

[0037] like Figure 1 As shown, in one embodiment, the lower end of the mounting frame 15 is arranged in an inverted U shape. When the plate at the lower end continues to be pushed, the plate moving therewith will push the waste plate after the previous stamping, causing it to fall through the lower end of the mounting frame 15 into the waste collection barrel.

[0038] The specific working method is: during operation, a waste collection barrel is placed on one side of the device, and multiple metal plates are placed inside the storage box 3 first. In the initial state, the push rod 14 is in contact with one side of the plate at the lower end, and the switch of the double-axis motor 5 is turned on. The double-axis motor 5 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the two connecting arms 1 7 fixed thereto to rotate, and then the two connecting arms 2 8 rotate and move, making a circular reciprocating motion, and finally drives the movable plate 9 to move, and then the fixed rod 13 and the push rod 14 move. The push rod 14 moves to push the plate so that the plate at the lower end moves to the stamping position. At this time, the switch of the hydraulic cylinder 16 is turned on, and its telescopic end is controlled to extend. The telescopic end of the hydraulic cylinder 16 extends to drive the mounting shaft 17 and the mold 18 to move downward, and the plate is stamped to form a specific The shaped parts and the stamped parts fall into the inner side of the collection box 23 through the through slot 101 and are collected uniformly. As the two connecting arms 1 7 rotate, the two connecting arms 2 8 are driven to move back. At this time, under the action of the gravity of the plates inside the storage box 3, multiple plates press down the push rod 14, and the push rod 14 moves down along the inner side of the fixed rod 13, thereby ensuring the return stroke of the fixed rod 13 and the push rod 14. When the push rod 14 moves to the side of the material dispensing port 20, the push rod 14 is reset by the elastic potential energy of the spring 141. Similarly, continue to push the plate at the lower end. The plate that moves therewith will push the waste plate after the previous stamping, so that it falls through the lower end of the mounting frame 15 into the waste collection cylinder. Through the above principle, automatic loading and unloading can be achieved.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
