Description

Technical Field

[0001] The present invention relates to the technical field of NdFeB magnet production, and in particular to a NdFeB magnet production device and method. Background Art

[0002] NdFeB magnets are one of the most powerful permanent magnet materials currently available. Due to their excellent magnetic properties and high energy density, they are widely used in electronics, automobiles, wind power generation, medical equipment and other fields. As the market demand for NdFeB magnets grows, production efficiency and product quality have become key considerations.

[0003] In the traditional NdFeB magnet production process, workers need to manually fill the pre-treated NdFeB powder into each forming hole of the first mold. The pressing equipment will then press the powder into shape to form a preliminary blank. After the pressing is completed, the operator must take out each blank from the first mold and accurately place it into the corresponding forming hole of the second mold for the next step of static pressing. This process is not only complicated and time-consuming, but also highly dependent on manual operation, resulting in low overall work efficiency. In addition, manual operation is prone to errors, such as uneven filling or offset pick-and-place positions, which may cause defects in the final product, thereby reducing the yield rate. For example, a slight difference in the filling amount may cause uneven density distribution, and irregular positioning may cause deviations in the shape of the blank. Summary of the invention
