Description

Technical Field

[0001] This utility model relates to the field of material forming device technology, and in particular to a samarium iron nitrogen permanent magnet ultrathin material forming device. Background Technology

[0002] Samarium iron nitride (SFIN) magnets are rare-earth permanent magnet materials with high magnetic properties and good magnetic stability. They have a wide range of applications, mainly in motors, generators, and various electronic products. SFIN magnets play an important role in electric vehicles, wind power generation, and power transmission systems, improving energy efficiency and reducing energy waste. In addition, they are also widely used in electronic devices such as hard disk drives, audio equipment, mobile phones, and computers. SFIN magnets have high magnetic energy density, which can be used to reduce product size and weight and improve product performance.

[0003] In general, samarium iron nitride magnets have a wide range of applications and are an indispensable material in modern technology. However, existing forming devices for ultra-thin samarium iron nitride permanent magnets cannot position and restrict the material, which makes it easy for errors to occur during stamping and reduces work efficiency. At the same time, after stamping, the stamping groove has a certain depth, making it difficult to remove the material, which makes it inconvenient to use and reduces its practicality.

[0006] Preferably, the forming mechanism includes a movable frame, a stamping rod, a limiting plate, a stamping plate, a spring, and a protective pad. One end of the hydraulic rod is connected to the movable frame. The movable frame is symmetrically provided with stamping rods. One end of the stamping rod is connected to the limiting plate, and the other end of the stamping rod is connected to the stamping plate. A spring is sleeved on the stamping rod, and a protective pad is provided at the bottom of the stamping plate. The protective pad is made of rubber.

[0007] Preferably, the ejection mechanism includes a servo motor, a bidirectional lead screw, a slider, a connecting rod, a connecting plate, and a push rod. The bidirectional lead screw is provided in the groove, and sliders are symmetrically provided at both ends of the bidirectional lead screw.

[0010] Preferably, the groove is provided with symmetrical rectangular slots, and an electric push rod is provided in the rectangular slot, with one end of the electric push rod connected to the positioning plate.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 4 As shown, a samarium iron nitrogen permanent magnet ultrathin material forming device includes a worktable 1, a forming mechanism and an ejection mechanism. A support frame 2 is provided on the surface of the worktable 1, and hydraulic cylinders 3 are symmetrically arranged on the surface of the support frame 2. The hydraulic cylinders 3 are connected to hydraulic rods 4. One end of the hydraulic rods 4 is connected to the forming mechanism. A groove is provided in the worktable 1, and a motor-driven lifting ejection mechanism is provided in the groove. The ejection mechanism is connected to a forming plate 5. The forming plate 5 pushes the upper forming material upward, thereby realizing the function of convenient unloading of the material after forming.

[0019] Reference Figure 1 , Figure 2 The forming mechanism includes a movable frame 6, a stamping rod 7, a limiting plate 8, a stamping plate 9, a spring 10, and a protective pad 11. One end of the hydraulic rod 4 is connected to the movable frame 6. The stamping rod 7 is symmetrically arranged inside the movable frame 6. One end of the stamping rod 7 is connected to the limiting plate 8, and the other end of the stamping rod 7 is connected to the stamping plate 9. The spring 10 is sleeved on the stamping rod 7, and the bottom of the stamping plate 9 is provided with a protective pad 11, which is made of rubber. The hydraulic cylinder 3 drives the hydraulic rod 4 to extend, which drives the movable frame 6 to move. When the stamping plate 9 comes into contact with the material, the hydraulic rod 4 continues to extend, which drives the stamping rod 7 to move upward to the maximum limit, and stamps the material to form it.

[0020] Reference Figure 3 , Figure 4 The ejection mechanism includes a servo motor 12, a bidirectional lead screw 13, a slider 14, a connecting rod 15, a connecting plate 16, and an ejector rod 17. The bidirectional lead screw 13 is housed within a groove, with sliders 14 symmetrically positioned at both ends. One end of the bidirectional lead screw 13 is connected to the output end of the servo motor 12. The slider 14 is rotatably connected to one end of the connecting rod 15, and the other end of the connecting rod 15 is rotatably connected to a connecting seat at the bottom of the connecting plate 16. Ejector rods 17 are symmetrically positioned on the surface of the connecting plate 16, with the other end of each ejector rod 17 connected to the forming plate 5. After stamping, the servo motor 12 operates, driving the sliders at both ends of the bidirectional lead screw 13. The movement of 14 causes the other end of the connecting rod 15 to drive the connecting plate 16 to rise, thereby driving the top rod 17 to lift the material, making it easier to remove and more convenient to use. The two-way lead screw 13 has opposite threads symmetrically on both ends. Guide rods 18 are symmetrically arranged on both sides of the inner wall of the groove. The guide rods 18 are slidably connected to the connecting plate 16. Rectangular grooves are symmetrically arranged in the groove. Electric push rods 19 are arranged in the rectangular grooves. One end of the electric push rod 19 is connected to the positioning plate 20. The electric push rods 19 on both sides work at the same time, driving the positioning plate 20 to move, thereby pushing the material to the center of the surface of the forming plate 5, so that the two ends of the material are symmetrical.

[0021] Working principle: When using this device, the material is placed on the forming plate 5, and the electric push rods 19 on both sides work simultaneously to move the positioning plate 20, thereby pushing the material. After the material is pushed, the electric push rods 19 move the positioning plate 20 to retract into the rectangular groove. The hydraulic cylinder 3 drives the hydraulic rod 4 to extend, which in turn moves the moving frame 6. When the stamping plate 9 comes into contact with the material, the hydraulic rod 4 continues to extend, which moves the stamping rod 7 upward to its maximum limit. After stamping, the servo motor 12 works, which moves the sliders 14 at both ends of the bidirectional lead screw 13, causing the connecting plate 16 to rise at the other end of the connecting rod 15, which in turn drives the top rod 17 to lift the material, making it easier to remove.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
