Description

Technical Field

[0001] This application relates to the field of powder metallurgy technology, specifically to a stamping device for powder metallurgy. Background Technology

[0002] Powder metallurgy is a process that uses metal powder (or a mixture of metal powder and non-metal powder) as raw material to manufacture metal materials, composite materials and various types of products through molding and sintering.

[0003] Stamping is a method of cold working metal sheets using dies. Through the relative movement of the punch and the die, the metal sheet is separated or deformed to obtain parts of the required shape and size. Stamping technology is widely used in the field of powder metallurgy to press metal powder into blanks of specific shapes for subsequent sintering.

[0004] For example, patent CN113333746B discloses a stamping device for powder metallurgy. This patent uses a motor to drive a feeding block to rotate, which can move the stamping material in the mold cavity, thereby improving the compaction and pressure uniformity of the stamping material in the mold cavity. Furthermore, the feeding block can generate vibration during movement, which helps to break the hollow layer in the stamping material in the mold cavity. Through the cooperation between the residual vibration guide rod, residual vibration spring, and residual vibration block, continuous vibration can be generated, thereby improving the effect of the feeding block in breaking the hollow layer in the stamping material.

[0005] During the implementation of the aforementioned patent, in the continuous stamping process, a set of metallurgical powder left over from the stamping process may adhere to the lower module. This may affect the surface quality of the product in the next stamping cycle. These residual powders may form defects, bumps or depressions on the surface of the product, reducing the appearance quality of the product.

[0022] like Figures 1-2 As shown, this application provides a stamping device for powder metallurgy, including a housing 1 and a stamping mechanism 2 fixedly installed on the upper end of the housing 1. The stamping mechanism 2 is used to stamp and form powder. The stamping mechanism 2 includes a base 21 fixedly connected to the upper end of the housing 1. Multiple sets of guide rods 22 are fixedly installed on the base 21. A stamping platform 23 is fixedly installed on the guide rods 22 and the guide rods 22 pass through the stamping platform 23. The stamping platform 23 is used for stamping work. Meanwhile, a first cylinder 24 is fixedly installed at one end of the stamping platform 23 away from the guide rod 22. A temporary storage box 25 is fixedly installed at the output end of the first cylinder 24. The interior of the temporary storage box 25 is a cavity to facilitate the temporary storage of powder. The temporary storage box 25 is provided with a feeding port (not shown in the figure) so that the powder can enter the interior of the temporary storage box 25 through the feeding port. The lower end of the inner cavity of the temporary storage box 25 is a through cavity. A sliding groove (not shown in the figure) is provided on the stamping platform 23. The sliding groove is adapted to the outer edge of the temporary storage box 25 so that the first cylinder 24 can push the temporary storage box 25 to slide along the stamping platform 23. Along the direction pushed by the first cylinder 24, a die opening is fixedly opened on the side of the stamping platform 23 away from the first cylinder 24 (not shown in the figure). At the same time, the die opening is adapted to the lower cavity of the temporary storage box 25 so that the powder in the temporary storage box 25 can fall smoothly into the die opening. Furthermore, a lower module 26 is fixedly installed at the lower end of the die opening. The lower module 26 passes through the stamping platform 23 and is slidably installed inside the stamping platform 23. At the same time, multiple sets of second cylinders 27 are fixedly installed on the base 21. The output end of the second cylinder 27 is fixedly connected to the lower module 26. The second cylinder 27 pushes the lower module 26 to slide up and down along the die opening inside the stamping platform 23. A frame 20 is fixedly installed at the top of the guide rod 22. A third cylinder 29 is fixedly installed on the frame 20. A fixing plate 28 is fixedly installed through the frame 20. An upper module 50 is fixedly installed at the lower end of the fixing plate 28. In order to facilitate the stamping of powder, the upper module 50 is positioned directly above the lower module 26. The third cylinder 29 is adapted to push the fixed plate 28 to drive the upper module 50 to approach the mold opening and enter, and to stamp the powder inside the mold opening. After the stamping is completed, the second cylinder 27 pushes the lower module 26 to push the finished part out along the mold opening. It should be noted that the size of the die opening is larger than the size of the fixed plate 28, so that the upper module 50 can enter the die opening for stamping. like Figures 2-3 As shown, a powder cleaning component 3 is fixedly installed on the side of the stamping platform 23 near the temporary storage box 25. The powder cleaning component 3 is used to clean the powder remaining on the lower module 26 and the stamping platform 23. The powder cleaning component 3 includes a sliding unit fixedly installed on both sides of the die opening. The sliding unit includes a slide rail 30 fixedly installed on the upper end of the stamping platform 23. A slider 33 is slidably connected to the upper end of the slide rail 30. A motor 31 is fixedly installed on one side of the slide rail 30. A lead screw 32 is fixedly installed at the output end of the motor 31, and the slider 33 is connected to the lead screw 32 for transmission. So when the motor 31 operates, it can drive the slider 33 to move along the direction of the slide rail 30. Two sets of fourth cylinders 34 are fixedly installed on the upper end of the slider 33. The sliding unit drives the fourth cylinders 34 to slide on both sides of the die opening. The fourth cylinder 34 is fixedly provided with a connecting block 35 at its upper end. A fixing rod 39 is fixedly provided at the lower end of the connecting block 35 at its central position. The fixing rod 39 is divided into an upper fixing rod and a lower fixing rod. A spring 37 is fixedly provided between the upper fixing rod and the lower fixing rod to provide a buffering effect on the lower module 26 during the dust cleaning operation and to prevent scratching the lower module 26. A scraper 38 is fixedly provided at the lower end of the lower fixing rod. The scraper 38 is used to scrape and clean the powder remaining on the lower module 26. It should be noted that when the first cylinder 24 pushes the temporary storage box 25 to slide along the stamping platform 23, the fourth cylinder 34 will push the scraper 38 to move upward, so that the temporary storage box 25 can move on the stamping platform 23. When the second cylinder 27 pushes the lower module 26 to push the finished part out along the mold opening, the fourth cylinder 34 will drive the scraper 38 to come closer to the lower module 26, so that the sliding unit drives the scraper 38 to move in the direction of the lower module 26 to remove the powder remaining on the lower module 26. like Figure 2 and Figure 4 As shown, a dust collection component 4 is fixedly installed on the side of the stamping platform 23 away from the first cylinder 24. The dust collection component 4 is used to remove and temporarily store the residual powder on the lower module 26. The dust collection assembly 4 includes a suction nozzle 41 fixedly installed on the upper end of the stamping platform 23, and a suction tube 42 fixedly installed on the side of the suction nozzle 41 away from the die opening, and the suction tube 42 is connected to the suction nozzle 41. A housing 43 is fixedly installed at the end of the suction tube 42 away from the suction nozzle 41. A vacuum pump 44 is fixedly installed inside the housing 43, and the vacuum pump 44 provides a power source for the vacuum assembly 4. Meanwhile, a storage cylinder 45 is fixedly installed on the stamping platform 23. The storage cylinder 45 is connected to the dust pump 44 so as to temporarily store the collected dust. When the dust on the module 26 is pushed by the scraper 38 to move along the stamping platform 23, the dust collection component 4 will absorb the dust pushed by the scraper 38 and the dust remaining on the stamping platform 23, and temporarily store the collected dust in a storage tube.
