[0022] like Figure 1-4 As shown, the working mechanism includes a stamping device 21, and two transmission rods 20 are fixedly connected to the bottom of the stamping device 21. The bottoms of the two transmission rods 20 are fixedly connected to transmission blocks 19. The two transmission rods 20 are movably embedded in the inner surface of the main body 1. The stamping device 21 can be driven downward by the deadweight of the stamped part to stamp the semi-finished product.

[0023] like Figure 1-4As shown, the feeding mechanism includes a moving block 13, which is fixedly connected to the outer surface of the rocker arm 12 near the top, and the outer surface of the moving block 13 is provided with two slide grooves 14, and the inner surfaces of the two slide grooves 14 are movably embedded with slide rods 15, and the outer surfaces of the opposite sides of the two slide rods 15 are fixedly connected with working blocks 16, and the bottom of the working block 16 is fixedly connected with two limit rods 17, and the outer surfaces of the two limit rods 17 are movably sleeved with springs 18, and the two springs 18 are fixedly connected to the bottom of the working block 16, and one end of the two springs 18 away from the working block 16 is fixedly connected to the bottom of the moving block 13, and the two limit rods 17 are movably embedded in the inner surface of the moving block 13, and the working block 16 is movably embedded in the inner surface of the body 1, and the spring 18 can provide power for the reverse movement of the working block 16, so that the working block 16 moves in the reverse direction.

[0024] like Figure 1-4 As shown, a positioning rod 23 is movably embedded in the inner surface of the rocker arm 12 near the bottom, and two positioning blocks 22 are fixedly connected to the outer surface of the positioning rod 23. The two positioning blocks 22 are fixedly connected to the top of the partition 6. The partition 6 can support the motor 7 and provide a good working environment for the motor 7.

[0025] like Figure 1-4 As shown, the transmission belt 5 is movably embedded in the inner surface of the main body 1 , and the transmission belt 5 can drive the semi-finished product to move, so that the semi-finished product moves to the bottom of the stamping equipment 21 .

[0026] Working principle: This equipment is a feeding device for four-claw nut stamping. When in use, the semi-finished product is placed in the semi-finished product groove on the transmission belt 5, and then the motor 7 on the partition 6 is started. The motor 7 drives the rotating shaft 8 to rotate through the output shaft, and the rotating shaft 8 drives the eccentric wheel 9 and the circular plate 10 to rotate. The circular plate 10 drives the connecting rod 11 to make an arc motion through the pin, and the connecting rod 11 drives the swing rod 12 to make an arc motion with the positioning rod 23 on the two positioning blocks 22 as the center of the circle. The swing rod 12 drives the moving block 13 to move, so that the moving block 13 retreats in the direction of the incoming material. When the working block 16 hits the contour of the flat groove on the transmission belt 5, the working block 16 will move to the inner surface of the moving block 13. The two slide grooves 14 and the slide rod 15 can limit the moving trajectory of the working block 16. When the working block 16 moves, it will squeeze the spring 18 on the outside of the two limit rods 17. The two springs 18 obtain elastic potential energy. When the working block 16 moves to the next flat groove, the two springs 18 will release the elastic potential energy, so that the working block 16 is re-stuck in the flat groove. At this time, the connecting rod 11 rotates to the upper half of the circular plate 10 and moves forward with the transmission belt 5. At this time, the eccentric wheel 9 is in a state of lifting the transmission block 19. Multiple fixed blocks 2, fixed rods 3 and pulleys 4 can provide a good working environment for the transmission belt 5. When the transmission belt 5 drives the semi-finished product to move to the bottom of the stamping equipment 21, the eccentric wheel 9 no longer lifts the transmission block 19, and the moving block 13 retreats in the direction of the incoming material. The transmission belt 5 is in a stationary state. The stamping equipment 21 will drive the stamping equipment 21 to move downward through the deadweight of the stamped part, and the stamping equipment 21 drives the two transmission rods 20 on the main body 1 to move downward, thereby stamping the semi-finished product.
