[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A multi-station powder metallurgy pressing and forming device includes a worktable 1, a U-shaped mounting frame 8 on the worktable 1, a stamping mechanism 2 on the U-shaped mounting frame 8, a lifting mechanism 3 at the bottom of the worktable 1, a mold frame 4 on the worktable 1, several rectangular grooves 5 arranged in a row inside the mold frame 4, a moving mechanism 6 on the worktable 1, and a feeding mechanism 7 on the moving mechanism 6. The stamping mechanism 2, the lifting mechanism 3, the moving mechanism 6 and the feeding mechanism 7 are integrated on the same control system.

[0023] When in use, the device uses the moving mechanism 6 to transport the feeding mechanism 7 to the top of the mold frame 4. The feeding mechanism 7 then feeds a fixed amount of powder into several grooves 5 on the mold frame 4. After the feeding is completed, the moving mechanism 6 drives the feeding mechanism 7 back to its initial position. Then, the stamping head of the stamping mechanism 2 is controlled to move downward to compact the powder in the grooves 5. Next, the output end of the lifting mechanism 3 moves upward to apply pressure from bottom to top to the powder in the grooves 5, thereby performing a secondary compaction process. After that, the stamping head of the stamping mechanism 2 is reset, and the lifting mechanism 3 operates again to push the powder block formed in the grooves 5 out of the mold frame 4, thus completing the demolding of the powder block.

[0024] Specifically, in this embodiment, the feeding mechanism 7 includes a storage bin 71 connected to the moving mechanism 6. The bottom of the storage bin 71 is provided with several distributing hoppers 72. The number and position of the distributing hoppers 72 correspond to the groove 5 and are connected to the storage bin 71. Each of the distributing hoppers 72 is provided with a pneumatic butterfly valve 73 at its outlet. The powder raw material is stored in the storage bin 71. The powder in the storage bin 71 can fall directly into the distributing hoppers 72. The pneumatic butterfly valve 73 controls the closing state of the outlet of the distributing hopper 72, thereby completing the powder feeding operation.

[0025] Specifically, in this embodiment, a weight sensor 74 is provided at the bottom of each of the several dispensing hoppers 72. The weight sensor 74 is electrically connected to the pneumatic butterfly valve 73. The weight sensor 74 can sense the weight of the powder in the dispensing hopper 72, thereby meeting the requirement of quantitative discharge of powder and avoiding the situation of powder waste caused by too much or too little powder being added.

[0026] Specifically, in this embodiment, the moving mechanism 6 includes connecting blocks 61 installed on both sides of the U-shaped mounting bracket 8 and two connecting brackets 62 installed on the workbench 1. A servo motor 63 is installed on the connecting bracket 62, and a threaded rod 64 is connected to the output shaft of the servo motor 63. A moving block 65 is threadedly connected to the threaded rod 64. The moving block 65 is connected to one side of the storage bin 71. When the servo motor 63 drives the threaded rod 64 to rotate, it can drive the moving block 65 to move, thereby achieving the purpose of moving the feeding mechanism 7 by the moving block 65.

[0027] Specifically, in this embodiment, a slider 66 is installed on the side of the storage bin 71 opposite to the moving block 65, and a sliding rod 67 is slidably connected to the slider 66. The sliding rod 67 is disposed between the connecting block 61 and the connecting frame 62 on the side opposite to the moving block 65, so that the storage bin 71 can be slidably connected to the sliding rod 67 through the slider 66, thereby restricting the movement direction of the storage bin 71, so that it can only move along the direction of the sliding rod 67.

[0028] Specifically, in this embodiment, the lifting mechanism 3 includes a mounting plate 31 installed at the bottom of the workbench 1. A cylinder 32 is installed at the bottom of the mounting plate 31. The output shaft of the cylinder 32 passes through the mounting plate 31 and is connected to a moving plate 33. Several lifting blocks 34 are connected to the moving plate 33. The several lifting blocks 34 are slidably adapted in the corresponding grooves 5, so that when the output shaft of the cylinder 32 moves upward, it can simultaneously drive the several lifting blocks 34 to move simultaneously, thereby achieving the purpose of applying pressure to the grooves 5 and realizing the purpose of secondary pressure application or demolding of the powder block.

[0029] Specifically, in this embodiment, a connecting groove 9 is provided on the workbench 1. The position of the connecting groove 9 corresponds to the position of the mold frame 4, and its size is larger than the size of the moving plate 33, so that the moving plate 33 can pass through the workbench 1 through the connecting groove 9, thereby facilitating the movement of several lifting blocks 34 in the vertical direction by the moving plate 33.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
