Description

Technical Field

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

[0002] Neodymium iron boron magnet is a kind of permanent magnetic material with excellent performance, which is widely used in electronics, electrical equipment and new energy vehicles. In the actual production process, in order to ensure the performance and assembly adaptability of neodymium iron boron magnet, the corners of neodymium iron boron magnet will be chamfered.

[0003] The traditional chamfering process mainly relies on chamfering equipment to chamfer NdFeB magnets. However, most chamfering equipment can only chamfer part of the corners of NdFeB magnets and cannot achieve comprehensive chamfering of all corners of NdFeB magnets. Since each chamfering can only process part of the corners, the NdFeB magnets need to be unloaded and then manually turned over before being put back into the chamfering equipment to process the remaining corners. The overall production cycle is long and takes a lot of time, resulting in reduced production efficiency. The entire process requires manual unloading, turning and reloading operations. This repetitive labor increases the workload of the staff and makes them easily tired. Summary of the Invention

[0004] In view of this, the present invention provides a chamfering processing device and a chamfering method for NdFeB magnet materials, which can overcome the problem of manually turning over and then putting it back into the chamfering equipment to process the remaining corners. The overall production cycle is long and it takes a lot of time, resulting in a decrease in production efficiency. The entire process requires manual unloading, turning over and reloading operations. This repetitive labor will increase the workload of the staff and cause the staff to be easily tired.
