Description

Technical field:

[0001] The utility model relates to the technical field of NdFeB production equipment, in particular to an outer diameter shaping tool for a bonded NdFeB magnetic ring product. Background technology:

[0002] Due to the expansion coefficient of raw materials and product structure problems, the bonded NdFeB magnetic ring products produced have an elliptical shape after molding. The product quality cannot meet customer requirements, because customers require that the roundness of magnetic ring products must be within a certain standard.

[0003] In order to meet customer requirements, magnetic ring products need to be shaped during production to ensure that product size and shape and position tolerances are within customer requirements. The current shaping solution is to use an inner diameter shaping gauge for shaping. Specifically, the magnetic ring products are placed on the inner diameter shaping gauge after baking and heating, and the magnetic ring products are manually pressed into the inner diameter shaping gauge. After the shaping is completed, the magnetic ring products are manually taken out.

[0004] However, manual shaping operations are inefficient and prone to burns. In addition, during the shaping process, the heat from the baked and heated magnetic ring products will gradually increase the temperature of the inner diameter shaping gauge. The thermal expansion and contraction of the inner diameter shaping gauge will affect the consistency of the product's dimensional tolerance. Moreover, since the magnetic ring products are close in size to the inner diameter shaping gauge, the magnetic ring products are very prone to cracks and damage. Utility model content:
