The plurality of electric mechanical claws 14 are all located above the conveying mechanism 16 and cooperate with the conveying mechanism 16. The plurality of electric mechanical claws 14 are arranged in one-to-one correspondence with the plurality of stamping grooves; Through the setting of a series of structures, the utility model can automatically stamp and form products, and can automatically complete the feeding and material taking operations before and after stamping, without the need for personnel to operate one by one, improving work efficiency and reducing labor intensity.

[0025] Working principle: When in use, the materials to be stamped can be placed at equal intervals on the top of the conveying mechanism 16. The conveying mechanism 16 conveys the stamping materials. When it is conveyed directly behind the stamping lower die base 100, the conveying mechanism 16 is stopped. Immediately afterwards, the push rod motor 15 is started in the forward direction. The output shaft of the push rod motor 15 drives a plurality of electric mechanical claws 14 to move downward out of the mounting holes through the moving rod. When the electric mechanical claws 14 move downward to contact the corresponding stamping materials, the corresponding stamping materials are grabbed by the electric mechanical claws 14. After the grabbing, the push rod motor 15 is started in the reverse direction, so that the electric mechanical claws 14 grab the stamping materials and turn them into being received upward into the mounting holes. Immediately afterwards, the second electric telescopic rod 11 is started in the forward direction. The output shaft of the second electric telescopic rod 11 drives the push plate 12 to move forward. The push plate 12 drives the electric mechanical claws 14 and the stamping materials inside it to move forward until they are aligned with the stamping grooves, and then the second electric telescopic rod 11 is stopped. Immediately afterwards, the push rod motor 15 is started in the forward direction again, so that the electric mechanical claws 14 grab the stamping materials and move downward into the corresponding stamping grooves. After being placed, the electric mechanical claws 14 relax the grasping force on the stamping materials. After being placed, the push rod motor 15 is started in the reverse direction, so that the electric mechanical claws 14 turn into moving upward into the mounting holes again, and the second electric telescopic rod 11 is started in the reverse direction, so that the push plate 12 drives a plurality of electric mechanical claws 14 to move backward and reset, thus completing the automatic feeding of the stamping materials;

[0026] After the feeding is completed, the first electric telescopic rod 102 can be started in the forward direction. The output shaft of the first electric telescopic rod 102 drives the stamping upper die base 101 to move downward for stamping and forming operations. After stamping, the first electric telescopic rod 102 is started in the reverse direction, so that the stamping upper die base 101 turns into moving upward. When the top of the stamping upper die base 101 moves upward and contacts the bottom of the moving block 9, the continuously upward moving stamping upper die base 101 squeezes the moving block 9 to move upward. The moving block 9 drives the corresponding guide rods 5 to move upward. The two guide rods 5 drive the moving plate 4 to move upward at the same time. When the moving plate 4 moves upward, it compresses a plurality of springs 6. The moving plate 4 also drives a plurality of push rods 7 to move upward. When the push rods 7 move upward, they push the formed products inside the corresponding stamping grooves upward, so that the formed products are moved out of the corresponding stamping grooves. After being moved out, the second electric telescopic rod 11 is started in the forward direction again, so that the push plate 12 moves forward again to push the moved out formed products forward into the collection box 10, thus completing the automatic material taking and collection after stamping. Through the automatic feeding and material taking methods, there is no need for personnel to operate one by one, improving work efficiency and reducing labor intensity;

[0027] After taking the material, drive the second electric telescopic rod 11 in the reverse direction to make the push plate 12 move backward to reset, then it can wait for the next use. At the same time, start the first electric telescopic rod 102 in the forward direction to make the stamping upper die base 101 move downward. When the stamping lower die base 101 moves downward, the extrusion force on the two moving blocks 9 is released. At this time, the elastic force of the compression spring 6 in the compressed state drives the moving plate 4 to move downward to reset, and the moving plate 4 drives the multiple push rods 7 to move downward to reset, then it can wait for the next material pushing operation.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
