Description
Technical Field
[0001] The utility model relates to the technical field of NdFeB clamping, in particular to a clamping device for sintering processing of heavy rare earth-free sintered NdFeB. Background Art
[0002] With the continuous advancement of rare earth permanent magnet material technology, heavy rare earth-free sintered NdFeB, as a high-performance permanent magnet material, has been widely used in new energy vehicles, wind power generation, energy-saving home appliances and other fields. In its production process, sintering is one of the key links, and the clamping device is an important auxiliary equipment for sintering, and its performance directly affects the processing accuracy and efficiency.
[0003] The reference patent (CN202322407592.6) discloses a clamping device for sintering NdFeB raw materials, including a mounting plate, a clamping mechanism is arranged on the top of the mounting plate, and a rotating mechanism is arranged on the top of the clamping mechanism. By setting the rotating mechanism, compared with the traditional clamping device for sintering NdFeB raw materials, when the NdFeB raw materials need to be turned over, there is no need to remove the NdFeB raw materials and readjust the angle, which saves time and improves the efficiency of processing the NdFeB raw materials. By setting the clamping mechanism, during the rotation of the threaded rod, the fixing parts on both sides can be driven to move in a direction close to each other, and the NdFeB raw materials can be clamped and fixed. At the same time, it can adapt to NdFeB raw materials of different sizes, which expands the scope of use of this device and improves the practicality of this device.
[0004] When a traditional clamping device clamps heavy rare earth-free sintered NdFeB, due to insufficient friction between the clamping surface and the material, it is easy to cause processing errors or material damage due to sliding or vibration during processing. The clamping surface is often fixed and cannot adapt to heavy rare earth-free sintered NdFeB materials of different specifications. When materials of different sizes or shapes need to be processed, the entire clamping device needs to be replaced, which not only increases the maintenance cost, but also reduces the versatility and utilization rate of the equipment. In addition, when the clamping device fixes the clamped object, it can often only achieve clamping on both sides, and lacks support for the bottom, which makes the object easy to shake or slide during processing, further affecting the processing accuracy and efficiency. For this reason, the utility model provides a clamping device for sintering processing of heavy rare earth-free sintered NdFeB. Utility Model Content
