DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following specifically introduces the present invention in combination with the accompanying drawings and specific embodiments.

[0018] An adjustable tungsten powder compaction device, as Figures 1-4As shown in the figure, it includes a base 1, guide rods 2, a placement block 3, a mold 4, a lifting frame 5, an electric push rod 6, a compaction assembly and a limiting assembly. On the upper sides of the front and rear parts of the base 1, two left and right guide rods 2 are connected respectively. A bottom plate is provided on the lower side of the base 1 for easy placement. A placement block 3 is connected between the lower parts of the guide rods 2. A mold 4 is slidably and detachably connected to the placement block 3. A lifting frame 5 is slidably connected to the mold 4. An electric push rod 6 is connected to the upper side of the middle part of the base 1. A push block is provided on the telescopic end of the electric push rod 6, and the push block is located below the lifting frame 5. A compaction assembly is provided between the guide rods 2. The compaction assembly includes a support plate 7, a hydraulic cylinder 8, a slider 9, a screw rod 10 and a pressing mold 11. A support plate 7 is connected between the upper sides of the guide rods 2. A hydraulic cylinder 8 is connected to the middle of the support plate 7. The lower side of the telescopic end of the hydraulic cylinder 8 is connected to a slider 9. The guide rods 2 are all slidably connected to the slider 9. A screw rod 10 is connected to the lower side of the middle part of the slider 9. A pressing mold 11 is threadedly connected to the screw rod 10. A limiting assembly is provided on the placement block 3. The limiting assembly includes a support block group 12, a bidirectional lead screw 13, a sliding frame 14 and a limiting block 15.

[0019] When using the present utility model, first place the base 1 in the tungsten powder compaction area, then fill the tungsten powder into the lifting frame 5 in the mold 4. After that, start the hydraulic cylinder 8 on the support plate 7 to push the slider 9 to move downward along the guide rod 2, so that the pressing mold 11 moves downward until it cooperates with the mold 4 to compact the tungsten powder into a preform with a specific size. After compaction, move the pressing mold 11 upward to reset, and then start the electric push rod 6 to make the push block move upward to push the lifting frame 5 upward to eject the pressed tungsten powder preform, which is convenient for the staff to take. When it is necessary to adjust the size of the tungsten powder preform, the pressing mold 11 can be removed from the screw rod 10, and then replace the pressing mold 11 with a corresponding size. Then rotate the bidirectional lead screw 13 on the support block 12 to move the sliding frames 14 away from each other, so that the limiting blocks 15 are separated from the mold 4, and the mold 4 is removed from the placement block 3 for replacement, thus playing the role of being able to conveniently replace different models of molds 4 to facilitate adjusting the size of the tungsten powder preform.
