Description

钕铁硼磁体延长的加工方法
技术领域
本发明涉及稀土永磁材料领域，特别涉及一种钕铁硼磁体延长的加工方法。
背景技术
磁体是能够产生磁场的物质，具有吸引铁磁性物质如铁、镍、钴等金属的特性。磁体一般分为永磁体(硬磁体)和软磁体，硬磁体又可以分为天然磁体和人造磁体，人造磁铁是指通过合成不同材料的合金可以达到与天然磁体(吸铁石)相同的效果，而且还可以提高磁力。20世纪60年代，稀土永磁的出现，则为磁体的应用开辟了一个新时代，第一代钐钴永磁SmCo5，第二代沉淀硬化型钐钴永磁Sm2Co17，迄今为止，发展到第三代钕铁硼永磁材料(NdFeB)。虽然目前铁氧体磁体仍然是用量最大的永磁材料，但钕铁硼磁体的产值已大大超过铁氧体永磁材料，已发展成一大产业。
随着稀土永磁材料应用领域的不断扩大，稀土永磁产品的样式也在不断的增多。目前，现有的钕铁硼产品在大尺寸上烧结难度大，易变形弯曲，使得磨削加工也困难。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容
本发明的目的在于提供一种钕铁硼磁体延长的加工方法，由易烧结的小尺寸产品，初步磨加工后，采用粘接的方法使产品形状发生改变，从而满足客户的要求，能够降低烧结难度及磨削加工难度，且产品不易变形弯曲。
为实现上述目的，本发明提供了一种钕铁硼磁体延长的加工方法，其包含如下步骤：(1)将烧坯粗磨加工得到磨坯；(2)将磨坯进行配料；(3)擦拭配料完成的磨坯；(4)将擦拭完成的多块磨坯粘接成所需要的大尺寸磨坯；(5)将大尺寸磨坯夹到夹具上并敲平整。
优选地，上述技术方案中，粘接时多块磨坯之间的平整度不超过20丝。
优选地，上述技术方案中，用丙酮擦拭磨坯。
优选地，上述技术方案中，用夹具夹紧的大尺寸磨坯需要放置6小时至8小时。
与现有技术相比，本发明具有如下有益效果：本发明的钕铁硼磁体延长的加工方法，由易烧结的小尺寸产品，初步磨加工后，采用粘接的方法使产品形状发生改变，从而满足客户的要求，能够降低烧结难度及磨削加工难度，且产品不易变形弯曲。
