[0029] The dust removal installation mechanism 8 includes a dust removal component 81 and an installation component 82, with the installation component 82 located at the bottom of the dust removal component 81.

[0030] Furthermore, the dust removal component 81 includes a connecting box 811, which is fixedly connected to the front of the dust inlet hood 7. A spring 813 is fixedly connected inside the connecting box 811, and a sliding plate 814 is fixedly connected to the bottom of the spring 813. A connecting block 812 is fixedly connected to the bottom of the sliding plate 814, which facilitates the dust removal by ensuring that the dust-adhesive roller 825 always adheres to the worktable 1.

[0031] Furthermore, grooves are provided at corresponding positions of the connecting box 811 and the connecting block 812, and the connecting block 812 is slidably connected inside the groove. Grooves are also provided at corresponding positions of the connecting box 811 and the sliding plate 814, and the sliding plate 814 is slidably connected inside the groove, which facilitates more stable use.

[0032] Furthermore, the installation component 82 includes a connecting platform 821, which is fixedly connected to the bottom of the connecting block 812. A first motor 822 is fixedly connected to the right side of the connecting platform 821. The output end of the first motor 822 extends through the connecting platform 821 and is fixedly connected to a bidirectional threaded rod 826 inside. A limit rod 827 is fixedly connected inside the connecting platform 821. A movable plate 823 is slidably connected to the outside of the limit rod 827.

[0034] Based on Embodiment 1, the existing technology cannot effectively remove the dust generated by the metal powder raw materials during the stamping process. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Figure 6, and further obtained in conjunction with Embodiment 1, the auxiliary cleaning mechanism 9 includes a support base 91, which is fixedly connected to the inner side of the support frame 2. A second motor 92 is fixedly connected to the end of the support base 91 away from the support frame 2. A rotating column 93 is fixedly connected to the output end of the second motor 92. A fixing block 94 is fixedly connected to the end of the support frame 2 near the support base 91. A dust suction plate 95 is rotatably connected inside the fixing block 94. A connecting rod 96 is rotatably connected inside the dust suction plate 95. A dust removal fan 97 is fixedly connected to the bottom of the workbench 1, which facilitates the up-and-down reciprocating swing of the dust suction plate 95, thereby increasing the dust removal range and satisfying the requirement to fully remove the dust generated by the metal powder raw materials during the stamping process.

[0035] Furthermore, a connecting pipe is provided between the dust suction plate 95 and the dust removal fan 97, and grooves are opened at the corresponding positions of the rotating column 93 and the connecting rod 96, and the connecting rod 96 is rotatably connected inside the groove, which facilitates a more stable suction process.

[0036] In actual operation, when this device is used, the powder inlet hood 7 is first connected to the external metal powder material conveying device. The external metal powder material conveying device then fills the powder inlet hood 7 with metal powder material. The cylinder 6 moves the powder inlet hood 7, pushing the metal powder material into the lower mold 5. The powder inlet hood 7 is then reset. The hydraulic cylinder 3 moves the upper mold 4, completing the stamping process. The movement of the powder inlet hood 7 moves the connecting block 812. This movement, in conjunction with the spring 813, moves the sliding plate 814, ensuring that the adhesive roller 825 remains in contact with the material. The workbench 1 is used for dust removal. When the ash-adhesive roller 825 needs to be processed, the first motor 822 is activated, causing the bidirectional threaded rod 826 to rotate. This, in conjunction with the limit rod 827, causes the movable plate 823 to move, thereby moving the connecting frame 824. This allows for the installation and removal of the ash-adhesive roller 825. The dust removal fan 97 is activated, working in conjunction with the connecting pipe and the dust suction plate 95 to remove the dust generated by the metal powder raw materials during the stamping process. The second motor 92 is activated, causing the rotating column 93 to rotate. This, in conjunction with the connecting rod 96, causes the dust suction plate 95 to rotate inside the fixed block 94, thereby causing the dust suction plate 95 to swing up and down.
