[0036] The mixing mechanism 6 includes a mixing barrel 601, which provides a space for containing metal powder. The outside of the mixing barrel 601 is fixedly connected to the outside of the base 1. The inside of the mixing barrel 601 is rotatably connected to a rotating shaft 602, and the rotating shaft 602 can rotate inside the mixing barrel 601.

At the same time, under the action of the elliptical groove plate 606, it can drive the pulling rod 608 to move up and down, so as to drive the rotating disk 609 to move up and down. Since the rotating disk 609 is rotatably connected to the inner side of the leakage disk 610, no motion interference will be generated. Then, the leakage disk 610 is driven up and down by the rotating disk 609, so that various powders are mixed more evenly.

[0037] The cleaning mechanism 7 includes a dust box 701, which can collect metal powder. The bottom of the dust box 701 is fixedly connected to the inner bottom end of the base 1. A connecting pipe 702 is fixedly connected to one side of the dust box 701. A limiting ring 703 is fixedly connected to the side of the connecting pipe 702 away from the dust box 701. The limiting ring 703 plays a limiting role. The outside of the limiting ring 703 is slidably connected to a sliding sleeve 704. The outer wall of the sliding sleeve 704 is provided with a plurality of exhaust holes 705. The outer wall of the connecting pipe 702 is provided with a plurality of air leakage holes 707. The exhaust holes 705 are aligned with the upper air leakage holes 70 After that, if there is a pressure difference inside the dust box 701, the external air can be sucked in to balance the air pressure inside the dust box 701, thereby playing a role in balancing the air pressure. The side of the limit ring 703 away from the dust box 701 is fixedly connected with a pressure spring 706, and the top of the inner part of the base 1 is fixedly connected with a dust suction head 708. The dust suction head 708 expands the area for sucking metal powder. One side of the dust suction head 708 is fixedly connected with a connecting elbow 709, and the bottom of the connecting elbow 709 is fixedly connected with an electromagnetic valve 710. The electromagnetic valve 710 can automatically control the switch, and the bottom of the electromagnetic valve 710 is fixedly connected At the top of the dust box 701, a powder discharge pipe 711 is fixedly connected to the side of the dust box 701 away from the stamping mechanism 5, and a plurality of powder suction holes 712 are opened on the top of the base 1. The side of the air pipe 509 away from the air cylinder 501 is fixedly connected to the outside of the dust box 701. When the air pipe 509 sucks away the air inside the dust box 701, a pressure difference is generated inside the dust box 701. When it is necessary to suck away the metal powder scattered on the top of the base 1, the solenoid valve 710 is started. Due to the pressure difference inside the dust box 701, suction is generated in the connecting elbow 709, and is expanded through the dust suction head 708. , so the suction force enters the interior of the dust suction head 708 through the powder suction hole 712, and then enters the interior of the dust box 701. When the powder inside the dust box 701 is cleaned, the cover on the powder discharge pipe 711 can be unscrewed and taken out. When the pressure difference inside the dust box 701 is too large, the exhaust hole 705 is sucked by the suction force to overcome the elastic force of the pressure spring 706 and move to one side of the dust box 701. When the exhaust hole 705 moves to the air leakage hole 707, the external atmospheric pressure can be sucked in, thereby reducing the pressure difference inside the dust box 701, and completing the pressure regulation inside the dust box 701.

[0038] Working principle: When the metal powder is pressed, the hydraulic cylinder 3 is first started, and the output end of the hydraulic cylinder 3 moves downward, thereby driving the upper punch 401 to move downward. After the upper punch 401 moves downward, the lower punch 404 is driven downward by the sliding column 402. When the bottom of the lower punch 404 contacts the top of the base 1, the mixed metal powder is put into the lower punch 404. At this time, the hydraulic cylinder 3 is started again to drive the upper punch 401 to move downward. When the upper punch 401 moves downward, the top of the push-pull curved rod 408 is driven downward. Under the cooperation of the slide bar 406 and the slide groove 405, the bottom of the push-pull curved rod 408 is forced to drive the scraper 407 to move on the top of the lower punch 404, so that the metal powder can be smoothed. At this time, the bottom of the upper punch 401 is still moving downward, so as to cooperate with the lower punch 404 to press the metal powder.

[0039] When the upper punch 401 moves downward, it drives the driving rod 506 to move downward, thereby driving the moving tube 503 to move downward, and then driving the movable sleeve 502 to move downward. At this time, the one-way valve 1 504 is opened, and the one-way valve 2 505 is closed. Therefore, the air inside the air cylinder 501 is discharged through the one-way valve 1 504. After the moving tube 503 moves downward, it can drive the rack plate 507 to move downward. When the moving tube 503 moves upward, the one-way valve 1 504 is closed, and the one-way valve 2 505 is opened. At this time, the air inside the cleaning mechanism 7 can be sucked away through the air pipe 509.

[0040] After the rack plate 507 moves downward, it can drive the transmission gear 605 to rotate, thereby driving the rotating rod 604 to rotate. After the rotating rod 604 rotates, it can drive the elliptical groove plate 606 and the driven bevel gear 607 to rotate. After the driven bevel gear 607 rotates, it can drive the active bevel gear 603 to rotate. After the active bevel gear 603 rotates, it can drive the rotating shaft 602 to rotate. After the rotating shaft 602 rotates, it can drive the leakage plate 610 to rotate through the cooperation of the limiting sliding rod 613 and the sliding groove 612, thereby driving the stirring block 611 to rotate to achieve the stirring effect. At the same time, under the action of the elliptical groove plate 606, it can drive the pulling rod 608 to move up and down, thereby driving the rotating disk 609 to move up and down. Since the rotating disk 609 is rotatably connected to the inner side of the leakage disk 610, no motion interference will occur. Then, the leakage disk 610 is driven up and down by the rotating disk 609, so that the mixing of multiple powders is more uniform.

[0041] After the air pipe 509 sucks away the air inside the dust box 701, a pressure difference is generated inside the dust box 701. When it is necessary to suck away the metal powder scattered on the top of the base 1, the solenoid valve 710 is started. Due to the pressure difference inside the dust box 701, suction is generated in the connecting elbow 709 and expanded through the dust suction head 708. Therefore, the suction enters the interior of the dust suction head 708 through the powder suction hole 712, and then enters the interior of the dust box 701. When the powder inside the dust box 701 is cleaned, the cover on the powder discharge pipe 711 can be unscrewed and taken out. When the pressure difference inside the dust box 701 is too large, the exhaust hole 705 is sucked by suction to overcome the elastic force of the pressure spring 706 and move to one side of the dust box 701. When the exhaust hole 705 moves to the air leakage hole 707, the external atmospheric pressure can be sucked in, thereby reducing the pressure difference inside the dust box 701 and completing the pressure regulation inside the dust box 701.
