[0025] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, a powder press with a preloading mechanism includes: a prepressing mechanism 1, the prepressing mechanism 1 includes a processing table 11, a pressing groove 12 is opened on the top of the processing table 11, a screw rod 13 is arranged in the slot opened on the top of the processing table 11, and both sides of the inner wall of the slot opened on the top of the processing table 11 are provided with sliding grooves 14, a moving frame 15 is arranged outside the screw rod 13, and both sides of the moving frame 15 are provided with sliders 16, the two ends of the screw rod 13 are respectively rotatably connected to the two sides of the inner wall of the slot opened on the top of the processing table 11, and the outside of the screw rod 13 is connected to the moving frame 15. The thread groove is threadedly connected, and sliders 16 are fixedly connected on both sides of the mobile frame 15. A mounting cylinder 17 is arranged in the card slot opened at the top of the mobile frame 15, and a pressure plate 18 is arranged on the top of the mounting cylinder 17. A connecting rod 19 is arranged at the bottom of the pressure plate 18. The outer surface of the slider 16 is slidably connected to the inner wall of the slide groove 14. The outside of the mounting cylinder 17 is fixedly connected to the card slot opened at the top of the mobile frame 15. The top of the connecting rod 19 is fixedly connected to the bottom of the pressure plate 18. Reset springs 110 are arranged in the two card slots opened at the bottom of the mounting cylinder 17. A pre-pressing block 1 is arranged at the bottom of the connecting rod 19. 12, the other end of the connecting rod 19 passes through the mounting tube 17 and the slot opened by the connecting block 111 and is fixedly connected to the top of the pre-pressing block 112, the outer surface of the connecting rod 19 is slidably connected to the inner wall of the slot opened by the mounting tube 17, a connecting block 111 is arranged on the outside of the connecting rod 19 near the top of the pre-pressing block 112, a blind 113 is arranged on the side of the mobile frame 15 away from the pressing groove 12, the inner wall of the slot opened by the connecting block 111 is fixedly connected to the outer surface of the connecting block 111, the top of the reset spring 110 is fixedly connected to the top side of the inner wall of the slot opened by the mounting tube 17, and the reset spring 110 is fixedly connected to the top side of the inner wall of the slot opened by the mounting tube 17. 0 bottom is fixedly connected to the top of the connecting block 111, one end of the blind 113 is fixedly connected to the side of the movable frame 15 away from the pressing groove 12, a pressing frame 114 is arranged on the top of the processing table 11, the other end of the blind 113 is fixedly connected to the inner wall of the slot opened on the top of the processing table 11 away from the pressing groove 12, the bottom of the pressing frame 114 is fixedly connected to the processing table 11, a telescopic cylinder 31 is fixedly installed in the slot opened on the top of the pressing frame 114, a pressing device 32 is fixedly connected to the bottom of the telescopic cylinder 31, and protective mechanisms 2 are arranged on both sides of the top of the processing table 11.

[0026] In this embodiment, when the staff needs to use the device to extrude the powder, the powder can be pre-processed first to ensure that the density of the powder is tighter. Therefore, the staff can place the powder in the pressing groove 12 and drive the movable frame 15 to move toward the pressing groove 12 by rotating the screw rod 13. During the movement of the movable frame 15, the slider 16 will slide in the slide groove 14, so that the movement of the movable frame 15 is smoother. When the pre-pressing block 112 and the pressing groove 12 are kept in the same vertical plane, the staff can transfer the pressure to the connecting rod 19 by pressing the pressing plate 18. When the connecting rod 19 is subjected to downward pressure, it will descend together with the connecting block 111 and the pre-pressing block 112, and then the pre-pressing block 112 will dock in the pressing groove 12 to preload and extrude the powder. During the descent of the connecting block 111, the return spring 110 will be pulled, and the return spring 110 will be stretched and deformed under the force. When the pressure plate 18 is released, the return spring 110 will lose the force and release the elastic force, thereby driving the pre-pressing block 112 to move upward and disengage from the pressing groove 12, and the powder in the pressing groove 12 will be preloaded and extruded. The density will be denser, and the moving frame 15 and the pre-pressing block 112 will be driven away from the pressing groove 12 by starting the screw rod 13 again, so as to avoid the pressing equipment 32 colliding with the pre-pressing mechanism 1 during the formal pressing process, and the pressing equipment 32 will be driven by starting the telescopic cylinder 31 to perform formal extrusion on the preloaded powder in the pressing groove 12. The curtain 113 can prevent the powder raised during the processing from falling on the screw rod 13, thereby extending the service life of the screw rod 13.

[0027] like Figure 1 and Figure 5 As shown, the protective mechanism 2 includes a protective plate 21, and one side of the bottom of the protective plate 21 is movably connected to one side of the top of the processing table 11 through a hinge. Two clamping blocks 22 are fixedly connected to one side of the top of the protective plate 21 close to the pressing frame 114. Two fixing grooves 23 are provided on both sides of the top of the pressing frame 114, and one end of the clamping block 22 close to the pressing frame 114 is clamped in the fixing groove 23.

[0028] In this embodiment, the protective plate 21 can not only reduce the damage to the equipment caused by accidents and extend its service life, but also confine dust and particulate matter in a closed space to reduce their diffusion to the surrounding environment, thereby protecting the health of workers and improving the safety of the workplace.

[0029] The utility model provides a powder press with a preloading mechanism, and the specific working principle is as follows:

[0030] When the staff needs to use the device to extrude the powder, the staff can place the powder to be processed in the pressing groove 12 of the device to ensure that the powder is evenly distributed in the groove. By rotating the screw 13, the staff can drive the movable frame 15 to move toward the pressing groove 12. This step is to ensure the correct positional relationship between the movable frame 15 and the pressing groove 12. During the movement of the movable frame 15, the slider 16 will slide in the slide groove 14. This design enables the slider 16 to move smoothly and provide stable support for subsequent preload extrusion. When the preload block 112 and the pressing groove 12 are maintained on the same vertical plane, the staff can transfer the pressure to the connecting rod 19 by pressing the pressure plate 18. This step is to ensure the correct alignment between the preload block 112 and the pressing groove 12 for effective preload extrusion. When the connecting rod 19 is subjected to downward pressure, it will descend together with the connecting block 111 and the preload block 112. In this way, the preload block 112 will dock in the pressing groove 12 to preload the powder. This process will make the density of the powder in the pressing groove 12 more compact, preparing for the subsequent formal extrusion process. During the descent of the connecting block 111, the reset spring 110 will be pulled. The reset spring 110 will be stretched and deformed after being subjected to the force. When the pressing plate 18 is released, the reset spring 110 will lose the force and release the elastic force, thereby driving the pre-pressing block 112 to move upward and disengage from the pressing groove 12. This design allows the pre-pressing block 112 to automatically reset after completing the preload extrusion, which is convenient for the next operation. In order to ensure that the pressing device 32 does not collide with the pre-pressing mechanism 1 during the formal pressing process, the movable frame 15 and the pre-pressing block 112 can be driven away from the pressing groove 12 by starting the screw rod 13 again, so as to provide enough space for the pressing device 32 to perform formal extrusion processing. Finally, the pressing device 32 is driven by starting the telescopic cylinder 31 to perform formal extrusion processing on the preloaded powder in the pressing groove 12. This step will enable the powder to form the desired shape and density under high pressure, completing the entire extrusion process.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
