[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1

[0025] like Figures 1-5As shown, a magnet forming device includes a processing platform 1. A connecting plate 11 is fixedly connected to the top of the protruding side of the processing platform 1. A first hydraulic cylinder 12 is installed on the top of the connecting plate 11. One end of the first hydraulic cylinder 12 is connected to a pressing plate 13. The middle part of the processing platform 1 is hollow. A U-shaped plate 14 is fixedly connected to the middle of the bottom surface of the processing platform 1. A second hydraulic cylinder 15 is installed in the middle of the U-shaped plate 14. One end of the second hydraulic cylinder 15 is connected to an ejector plate 16. The four sides of the ejector plate 16 match the four sides of the hollow part in the middle of the processing platform 1. A smoothing component is provided in the middle of the processing platform 1.

[0026] The smoothing assembly includes a mold 2, a pallet 21, a hollow connecting box 22, a rectangular groove 23, and a servo motor 24. The bottom of the mold 2 is fixed to the hollow part in the middle of the processing platform 1. The bottom of the pallet 21 is fixed to one corner of the top surface of the processing platform 1. The bottom of the hollow connecting box 22 is fixed to the top of the mold 2. The rectangular groove 23 is opened on the side of the hollow connecting box 22 away from the pallet 21. The servo motor 24 is installed on the top of the pallet 21.

[0027] The smoothing assembly also includes a first lead screw 3, a threaded sleeve 31, a connecting rod 32, and a rectangular smoothing plate 33. One end of the first lead screw 3 is connected to the output end of the servo motor 24. One end of the connecting rod 32 is fixed to the top of the threaded sleeve 31. The middle of the top surface of the rectangular smoothing plate 33 is fixed to the other end of the connecting rod 32. Both ends of the rectangular smoothing plate 33 are respectively attached to the inner walls of the two sides of the hollow connecting box 22, and the four sides of the rectangular smoothing plate 33 match the four sides of the rectangular groove 23. A storage mechanism is provided at one end of the first lead screw 3.

[0028] During operation, magnetic material powder is first placed inside mold 2, and then the smoothing component is driven to smooth the powder inside mold 2. Then, the first hydraulic cylinder 12 is activated, thereby driving the pressing plate 13 to press downward, thus pressing the material inside mold 2 into shape. After shaping, the pressing plate 13 can be raised with the help of the first hydraulic cylinder 12, and then the second hydraulic cylinder 15 is activated, thereby driving the ejector plate 16 to move upward, thus ejecting the shaped magnet from inside mold 2.

[0029] When the smoothing component is running, the servo motor 24 can be activated first to drive the first lead screw 3 to rotate. When the first lead screw 3 rotates, it will drive the threaded sleeve 31, the connecting rod 32, and the rectangular smoothing plate 33 to move synchronously. As the rectangular smoothing plate 33 moves, its two ends are in contact with the inner walls of the hollow connecting box 22, so the movement trajectory of the rectangular smoothing plate 33 can be restricted, thereby causing the rectangular smoothing plate 33, the connecting rod 32, and the first lead screw 3 to slide linearly towards the rectangular groove 23. During the sliding process of the rectangular smoothing plate 33, the uneven magnetic material powder inside the mold 2 can be smoothed until the rectangular smoothing plate 33 moves to the rectangular groove 23 and is in contact with the rectangular groove. When the rectangular flat plate 33 and the rectangular groove 23 are aligned, the operation of the servo motor 24 can be stopped. At the same time, as the rectangular flat plate 33 moves towards the rectangular groove 23, it will push the powder on the protruding part from the rectangular groove 23 to the top surface of the processing platform 1. After the rectangular flat plate 33 and the rectangular groove 23 are aligned, the first hydraulic cylinder 12 can be driven to press the powder inside the mold 2. After pressing and forming, the servo motor 24 can be driven to drive the first lead screw 3 to reverse, so that the rectangular flat plate 33 is disengaged from the rectangular groove 23 and reset. After the rectangular flat plate 33 is reset, the formed magnet can be ejected with the help of the ejector plate 16. Then, the interior of the mold 2 can be filled with magnetic material powder again to carry out the second batch of magnet forming work.

[0030] This step, through the setting of the smoothing component, can smooth the magnetic material powder filling the inside of mold 2 before pressing, thereby ensuring that the powder is evenly filled inside mold 2, improving the balance of force on each part during pressing, thereby improving the uniformity of magnet density and dimensional accuracy, enhancing the magnetic stability and surface quality of the magnet, and improving the product qualification rate.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the storage mechanism includes a worm gear 4, a first support plate 41, an L-shaped support plate 42, and a second support plate 43. One end of the worm gear 4 is connected to the end of the first lead screw 3 away from the servo motor 24. The bottom of the first support plate 41 is fixed to a corner of the top surface of the processing platform 1 away from the support plate 21. The end of the worm gear 4 away from the first lead screw 3 is rotatably connected to the top of the first support plate 41. The bottom end of the L-shaped support plate 42 is fixed to the side of the processing platform 1. The bottom of the second support plate 43 is fixed to the top surface of the processing platform 1 away from the L-shaped support plate 42.

[0033] The storage mechanism also includes a second lead screw 5, a worm gear 51, and a collection box 52. The two ends of the second lead screw 5 are rotatably connected to the middle of the second support plate 43 and the L-shaped support plate 42, respectively. The worm gear 51 is fixed to one end of the second lead screw 5 near the second support plate 43, and the worm gear 51 meshes with the worm 4. One side of the collection box 52 is fixed to the side of the processing platform 1 near the L-shaped support plate 42.

[0034] The storage mechanism also includes a threaded slider 6 and a scraper 61. The middle part of the threaded slider 6 is threadedly connected to the middle part of the second lead screw 5. One end of the scraper 61 is fixed to the middle part of the threaded slider 6, and the bottom surface of the scraper 61 is in contact with the top surface of the processing platform 1.

[0035] During operation, when the first lead screw 3 rotates, it drives one end of the worm gear 4 to rotate in the middle of the first support plate 41. The rotation of the first support plate 41 drives the worm wheel 51 to drive the second lead screw 5 to rotate. When the second lead screw 5 rotates, its two ends rotate in the middle of the L-shaped support plate 42 and the second support plate 43, respectively. During the rotation of the second lead screw 5, it also drives the threaded slider 6 and the scraper 61 to move synchronously. At this time, because the bottom of the scraper 61 is in contact with the top surface of the processing platform 1, the movement trajectory of the scraper 61 and the threaded slider 6 can be restricted, so that the scraper 61 and the threaded slider 6 move in a straight line. During the movement, the scraper 61 can clean up the excess powder pushed out by the rectangular flat plate 33, so that the powder is cleaned into the collection box 52.

[0036] This step, through the setting of the collection mechanism, can clean and collect the powder scattered on the top surface of the processing platform 1, thereby improving the cleanliness of the surface of the processing platform 1, and can also reduce the workload of operators, thereby improving work efficiency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
