[0028] Reference Figures 1 to 5 As shown, an adjustable metering box is provided, belonging to the field of metallurgical powder molds. It includes a fixed platform 1, a screw drive assembly 2 on the fixed platform 1, a reciprocating pressure plate 3 fixedly connected to the output end of the screw drive assembly 2, a base plate 4 fixedly connected to the other end of the pressure plate 3, a pushing device 8 on the base plate 4, a metering plate 5 fixedly connected to the output end of the pushing device 8, a hopper 6 fixedly installed on the metering plate 5, a feeding through hole 51 that can communicate with the hopper 6 on the metering plate 5, a metering adjustment assembly 9 movably installed on the feeding through hole 51 to adjust the volume of the feeding through hole 51, a cavity plate 10 at the bottom end of the base plate 4, a base plate hole 41 on the base plate 4, and a cavity hole 101 on the cavity plate 10, which can be connected with the base plate hole 41 and the feeding through hole 51.

[0029] In this embodiment, the screw drive assembly 2 drives the pressure plate 3 to move linearly, thereby moving the base plate 4 to achieve precise alignment between the base plate 4 and the hole on the cavity plate 10. The pushing device 8 pushes the metering plate 5 to precisely align the feeding through hole 51, the base plate hole 41, and the cavity hole 101, achieving three-hole overlap. Before the three holes overlap, the metering plate 5 moves to the hopper 6 and connects with the feeding through hole 51. The powder on the hopper 6 falls into the feeding through hole 51, and then the three holes overlap. The amount of powder falling into the feeding through hole 51 can be adjusted by the metering adjustment assembly 8 to control the volume of the feeding through hole 51. This device can effectively solve the problems of poor adaptability and insufficient precision of existing devices, meeting the high consistency production requirements of metallurgical powder pressing.

[0030] In some embodiments of this utility model, the quantitative adjustment component 9 includes two quantitative adjustment sliders 91, a first quantitative adjustment motor 92, and a second quantitative adjustment motor 93. The first quantitative adjustment motor 92 and the second quantitative adjustment motor 93 are respectively symmetrically installed at the end of the base plate 4 away from the pressure plate 3. The two quantitative adjustment sliders 91 are respectively connected to the output ends of the first quantitative adjustment motor 92 and the second quantitative adjustment motor 93. The two quantitative adjustment sliders 91 are movably disposed on the feeding through hole 51 to adjust the volume of the feeding through hole 51.

[0031] In some embodiments of this utility model, a limiting hole 911 is provided on the quantitative adjustment slider 91, and a limiting block 52 that cooperates with the limiting hole 911 is provided on the quantitative plate 5. The limiting block 52 is a detachable installation structure. When assembling the quantitative adjustment slider 91, the quantitative adjustment slider 91 is first placed into the feeding through hole 51, and then the limiting block 52 is inserted, so that it passes through the limiting hole 911 on the quantitative adjustment slider 91, thereby preventing the quantitative adjustment slider 91 from falling off during assembly.

[0032] In some embodiments of this utility model, the output ends of the first quantitative adjustment motor 92 and the second quantitative adjustment motor 93 are both provided with external threads, and the quantitative adjustment slider 91 is provided with an assembly hole. The assembly hole is provided with an internal thread that mates with the external thread. Thus, when the two quantitative adjustment motors are driven, the two quantitative adjustment sliders 91 can move back and forth. The two quantitative adjustment sliders 91 can move independently within the feeding through hole 51, forming a quantitative cavity with an adjustable volume. By adjusting the relative position of the two quantitative adjustment sliders 91, the volume of the quantitative cavity can be steplessly adjusted.

[0033] In some embodiments of this utility model, a hopper base 20 is fixedly installed on the top of the metering plate 5, and a hopper 6 is fixedly installed above the hopper base 20.

[0034] Furthermore, the hopper base 20 has a U-shaped structure. The bottom of the hopper 6 is provided with a first through hole 61, and the hopper base 20 is provided with a second through hole 201 that communicates with the first through hole 61. This allows the second through hole 201 to communicate with the feeding through hole 51 after the metering plate 5 moves. The hopper base 20 spans the metering plate 5 and is fixedly connected to the base plate 4. Therefore, the hopper 6 will not move with the metering plate 5, but will move with the base plate 4.

[0035] In some embodiments of this utility model, the lead screw drive assembly 2 includes a first motor 21, a lead screw 22, and a slider 23. The output end of the first motor 21 is connected to the lead screw 22. The lead screw 22 is provided with a movable nut seat. The slider 23 is fixedly installed on the nut seat so that the slider 23 can move back and forth along the length direction of the fixed platform 1. The slider 23 is fixedly connected to the pressure plate 3.

[0036] In some embodiments of this utility model, the pushing device 8 is configured as a cylinder, which is fixedly installed on the bottom plate 4 near the pressure plate 3.

[0037] In some embodiments of this utility model, a vibrator 30 is fixedly installed on the base plate 4.

[0038] In some embodiments of this utility model, the hopper 6 is provided with a connection port 62 that communicates with the interior.

[0039] In this embodiment, the first motor 21 drives the lead screw 22 to rotate, causing the slider 23 and the pressure plate 3 to move the base plate 4 linearly, achieving precise alignment between the base plate hole 41 and the cavity hole 101; the output end of the pushing device 8 pushes out, pushing the powder from the feeding through hole 51 to precisely align with the base plate hole 41 and the cavity hole 101, achieving three-hole overlap; the vibrator 30 starts vibrating, ensuring that the powder from the feeding through hole 51 and the base plate hole 41 completely falls into the cavity hole 101; the first motor 21 drives the lead screw 22 to reset the slider 23 and the pressure plate 3, and the pushing device 8 resets, causing the metering plate 5 to reset, preparing for the next filling, and then triggering the mold to close and press, completing one production cycle.

[0040] The hopper 6 is used to store powder materials; the pushing device 8 drives the metering plate 5 to slide and controls the opening and closing of the feeding through hole 51; the pressure plate 3 is used to push the components on the base plate 4 to move. This device can solve the problems of poor adaptability, insufficient precision, serious residue and weak linkage of existing devices, and meet the high consistency production requirements of metallurgical powder pressing.

For those skilled in the art, simple deductions or substitutions without departing from the concept of this utility model are all within the protection scope of this utility model.
