[0028] Working principle:

[0029] First, the operator places the powder to be pressed in the feeding box 29, and then the operator starts the first motor 13, the first motor 13 drives the first screw 14, and the first screw 14 drives the first slider 16. The initial position of the first slider 16 is on the left side of the workbench 1. When the feeding chamber 30 on the first slider 16 is above the pressing hole 7, the operator feeds the powder in the feeding pipe 32 into the pressing hole 7 through the solenoid valve 31. Then, the operator starts the first motor 13 again to move the first slider 16 to the initial position. Then, the operator starts the first cylinder 5, and the first cylinder 5 drives the upper mold 6 to approach the lower mold 8 in the pressing hole 7. Under the action of the first cylinder 5, the upper mold 6 performs preliminary pressing on the powder. Then, the operator starts the second cylinder 9 to drive the lower mold 8 to press the powder again. When the powder is pressed and formed, the operator starts the first cylinder 5 away from the pressing hole 7. Then, the operator starts the second cylinder 9 again to push the part above the lower mold 8 out of the pressing hole 7.

[0030] Afterwards, the operator starts the first motor 13 again, and the first motor 13 drives the first slider 16 to move toward the part. When the two clamping plates 10 on the connecting rod 17 are located on both sides of the part, the operator starts the first gas rod 18, so that the two clamping plates 10 complete the clamping of the part. Then the operator moves the first slider 16, and the first slider 16 drives the two clamping plates 10 to move to the outside of the workbench 1. When the first slider 16 moves, the scraper 37 can push the excess powder on the surface of the workbench 1 to the inclined plate 33, so that the powder falls into the collection box 34 through the inclined plate 33, and the filter plate 39 in the collection box 34 can filter the powder.

[0031] After that, the operator starts the second motor 22, and the second unit drives the second screw 20 to move the second slider 23, and then starts the third motor 25 again. The third motor 25 drives the third screw 24 to move the third slider 27, thereby moving the mechanical claw 12 above the two clamping plates 10. Then the operator starts the second air rod 28, and the second air cylinder drives the mechanical claw 12 to move toward the part. After the mechanical claw 12 completes clamping of the part, the two clamping plates 10 move away from the part and return to the initial position. Then the mechanical claw 12 places the part on the placement plate 11. The operator can take the placement plate 11 to complete the collection of the pressed parts.
