Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet production technology, specifically to a pressing and molding device for neodymium iron boron magnet production. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are intermetallic compounds composed of rare earth element neodymium (R) and iron and boron. R is primarily neodymium or a combination of neodymium and other rare earth elements; sometimes cobalt, aluminum, vanadium, etc., are used to replace some of the iron. They exhibit strong magnetocrystalline anisotropy and very high saturation magnetization.

[0003] Most existing devices do not have a fixed mold, which leads to two problems: first, the pressing mold cannot be replaced; second, after replacement, it cannot be fixed. Either way, it affects the efficiency of use and causes inconvenience.

[0004] To address the aforementioned problems, existing technologies provide a solution. For example, patent publication number CN220532974U provides a pressing and forming device for producing neodymium iron boron magnets, including a fixed structure and a clamping structure. The clamping structure is disposed on the outer surface of the fixed structure and includes a clamping plate unit, a gear rotating unit, a support unit, and a motor transmission unit. The clamping plate unit is movably connected to the top surface of the fixed structure, the gear rotating unit is fixedly connected to the bottom surface of the clamping plate unit, the support unit is fixedly connected to the bottom surface of the fixed structure, and the motor transmission unit is fixedly connected to the bottom surface of the fixed structure. This pressing and forming device for producing neodymium iron boron magnets starts with a left-right moving motor and a front-back moving motor, which drive a transmission belt to rotate. The transmission belt drives a saw gear to rotate, and through the meshing of the saw teeth and the saw gear, the saw teeth move inward, causing the left-right clamping plates and the front-back clamping plates to move inward, clamping and fixing the pressing mold. Although the existing device can ensure that the neodymium iron boron magnet does not shake during the forming process and can improve the forming quality of the neodymium iron boron magnet, it can also cause the neodymium iron boron magnet to stick to the limiting device after pressing and forming, making it difficult to separate the neodymium iron boron magnet from the limiting device.

[0005] To address this, a pressing and molding device for the production of neodymium iron boron magnets is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a pressing and molding device for the production of neodymium iron boron magnets, thereby solving the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pressing and forming device for producing neodymium iron boron magnets includes a top plate, a support plate, and legs. It also includes a cylinder, a connecting mechanism, a pressure plate, a main rack, a vibrating mechanism, and a lower plate. The cylinder is connected to the top plate, the connecting mechanism is connected to the cylinder, the pressure plate is connected to the connecting mechanism, the main rack is connected to the pressure plate, the vibrating mechanism is connected to the main rack, and the lower plate is connected to the vibrating mechanism. When the cylinder is activated, the connecting mechanism controls the pressure plate to move towards the lower plate to extrude and form the neodymium iron boron magnet. When the pressure plate descends, the main rack descends synchronously and controls the vibrating mechanism to cause the lower plate to vibrate.

[0009] Preferably, the connecting mechanism includes a fixed sleeve, a telescopic spring, and a connecting rod. The fixed sleeve is connected to the top plate, the telescopic spring is connected to the fixed sleeve, and the connecting rod is connected to the telescopic spring.

[0010] Preferably, four fixing sleeves are symmetrically arranged around the center line of the top plate, and the axis of the fixing sleeve and the connecting rod coincides with the vertex of the pressure plate.

[0011] Preferably, the vibration mechanism includes a gear, a secondary rack, a cam, a limiting block, a limiting rod, a return spring, a connecting plate, and a guide rod. The gear meshes with the main rack, the secondary rack meshes with the gear, the cam meshes with the secondary rack, the limiting block is connected to the cam, the limiting block is connected to the limiting rod, the return spring is connected to the limiting block, the connecting plate is connected to the secondary rack, and the guide rod is connected to the connecting plate.

[0012] Preferably, the length of the main rack is 1.5 times the length of the secondary rack.

[0013] Preferably, the lower plate has limit grooves at both ends, and the limit block, limit rod and reset spring are all installed in the limit grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By controlling the cam to strike the lower plate when the pressure plate and the lower plate approach each other, vibration is generated, which allows the NdFeB magnets in the lower plate to be evenly distributed. This ensures that the NdFeB magnets are formed evenly under the action of the pressure plate, thus improving the quality of the NdFeB magnet forming. At the same time, when the pressure plate and the lower plate gradually separate, the cam strikes the lower plate, and the vibration separates the NdFeB magnets from the lower plate, making it easier to pick up the formed NdFeB magnets.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0024] Reference Figures 1 to 6 A pressing and forming device for producing neodymium iron boron magnets includes a top plate 1, a support plate 2 and a support leg 3, as well as a cylinder 4, a connecting mechanism 5, a pressure plate 6, a main rack 7, a vibrating mechanism 8 and a lower plate 9. The cylinder 4 is connected to the top plate 1, the connecting mechanism 5 is connected to the cylinder 4, the pressure plate 6 is connected to the connecting mechanism 5, the main rack 7 is connected to the pressure plate 6, the vibrating mechanism 8 is connected to the main rack 7, and the lower plate 9 is connected to the vibrating mechanism 8. When the cylinder 4 is started, the connecting mechanism 5 controls the pressure plate 6 to move towards the lower plate 9 to extrude and form neodymium iron boron magnets. When the pressure plate 6 descends, the main rack 7 descends synchronously and controls the vibrating mechanism 8 to drive the lower plate 9 to vibrate.

[0025] As one embodiment of this utility model, refer to Figures 3 to 5The connecting mechanism 5 includes a fixed sleeve 51, a telescopic spring 52, and a connecting rod 53. The fixed sleeve 51 is connected to the top plate 1, the telescopic spring 52 is connected to the fixed sleeve 51, and the connecting rod 53 is connected to the telescopic spring 52. Four fixed sleeves 51 are symmetrically arranged around the center line of the top plate 1. The axis of the fixed sleeve 51 and the connecting rod 53 coincides with the vertex of the pressure plate 6. Through the above arrangement, the pressure plate 6 can maintain uniform force at the four corners when pressing and molding the neodymium iron boron magnet, and can avoid poor molding quality caused by uneven force at the center and four corners of the pressure plate 6.

[0026] As one embodiment of this utility model, refer to Figures 4 to 6 The vibration mechanism 8 includes a gear 81, a secondary rack 82, a cam 83, a limit block 84, a limit rod 85, a return spring 86, a connecting plate 87, and a guide rod 88. The gear 81 meshes with the main rack 7, the secondary rack 82 meshes with the gear 81, the cam 83 meshes with the secondary rack 82, the limit block 84 is connected to the cam 83, the limit block 84 is connected to the limit rod 85, the return spring 86 is connected to the limit block 84, the connecting plate 87 is connected to the secondary rack 82, and the guide rod 88 is connected to the connecting plate 87. The main rack 7 has a length... The length value is 1.5 times the length value of the secondary rack 82. With the above setting, the main rack 7 and the secondary rack 82 can drive the cam 83 to rotate at the same time when they move in a cross motion. Limiting grooves 89 are opened at both ends of the lower plate 9. The limiting block 84, the limiting rod 85 and the return spring 86 are all installed in the limiting grooves 89. The setting of the limiting grooves 89 can provide space for the movement of the limiting block 84, and at the same time prevent the cam 83 from jamming. It can ensure that the cam 83 strikes the lower plate 9 while rotating, so that the lower plate 9 vibrates.

[0027] Working principle: During use, the user places the neodymium iron boron magnet to be formed into the lower plate 9, and then starts the cylinder 4. The cylinder 4 drives the pressure plate 6 to descend. When the pressure plate 6 descends, it can drive the connecting rod 53 to move within the fixed sleeve 51 and stretch the extension spring 52. At the same time, it can drive the main rack 7 to descend. When the main rack 7 descends, it can drive the gear 81 to rotate. When the gear 81 rotates, it can drive the lower plate 9 to rise through the secondary rack 82. When the lower plate 9 rises, it can drive the cam 83 to rise synchronously. The rising cam 83 and the descending... The main rack 7 engages, striking the lower plate 9. The lower plate 9 vibrates when struck, which helps to evenly distribute the neodymium iron boron magnets inside the lower plate 9. The lower plate 9 lifts the neodymium iron boron magnets to fit against the pressure plate 6. The pressure plate 6 then descends to shape the neodymium iron boron magnets. Then, the cylinder 4 is activated again, causing the pressure plate 6 to gradually separate from the lower plate 9. The cam 83 strikes the lower plate 9 again, which separates the shaped neodymium iron boron magnets from the lower plate 9, making it easier to remove the shaped neodymium iron boron magnets.
