[0053] Specifically, the second vibrating hammer 445 is securely connected to the second mounting plate 41 via bolts, and the third vibrating hammer 447 is securely connected to the third mounting plate 42 via bolts. The second and third vibrating hammers 445 and 447 intermittently transmit vibrations directly to the second mounting plate 41 and the parts to be cleaned 8 located thereon, or to the third mounting plate 42 and the parts to be cleaned 8 located thereon, thereby loosening and removing stubborn powder residue from the surfaces of the parts to be cleaned 8. The second vibrator 446 is bolted to the first flip beam, and the third vibrator 448 is bolted to the second flip beam 43. The second and third vibrators 446 and 448 continuously vibrate to further remove powder from the parts to be cleaned 8.

[0054] In this embodiment, by combining the continuous vibration of the second vibration hammer 445 with the second vibrator 446 and combining the continuous vibration of the third vibration hammer 447 with the third vibrator 448, it is convenient to further remove the stubborn powder residue on the surface of the part 8 to be cleaned, thereby improving the powder cleaning effect.

[0060] Specifically, a rubber glove is placed on the manual hinge door 7. The rubber glove is connected to the sealing surface inside the manual hinge door 7, and the outer portion of the rubber glove forms a sealed joint with the sealing surface of the box body 2. When the operator puts on the glove and inserts his hand into the glove, he is actually performing operations inside the glove. In this way, the operator can perform necessary interventions inside the box body 2, such as manually cleaning stubborn powder and checking the condition of the workpiece, without opening the manual hinge door 7 and without damaging the sealing of the box body 2, further improving the powder cleaning effect.

[0061] In this embodiment, the manual hinge door 7 provides a simple and direct loading and unloading channel for the parts to be cleaned 8. The operator can easily put the parts to be cleaned 8 into or out of the box 2 through the manual hinge door 7 without additional auxiliary equipment, which greatly saves time and labor costs.

[0062] The working principle of the metal 3D printing part powder cleaning system of the present invention is as follows: when cleaning the part 8 to be cleaned, the drive motor 52 is started, and the drive motor 52 drives the two output ends of the dual-axis reducer 51 to rotate, and the two output ends of the dual-axis reducer 51 respectively drive the first flip beams connected to them to perform horizontal flipping movement, and the first flip beam drives the first mounting plate and the part to be cleaned 8 located on the first mounting plate to perform horizontal flipping movement synchronously, thereby achieving the cleaning of the part 8 to be cleaned.
