Description

一种烧结钕铁硼压机储料仓放料处理装置及方法
技术领域
本发明涉及一种烧结钕铁硼压机储料仓放料处理装置及方法。
背景技术
在永磁材料中，钕铁硼永磁材料的综合磁性能最好，并且烧结法优于粘结法。成型工序是烧结钕铁硼永磁制品的关键工序之一。烧结钕铁硼成型工艺采取的是干粉压制，其生产步骤为：压机、模具准备（高性能氧含量控制）—称粉—加料—充磁—压制成型—退磁—保压脱模—封装—检查—等静压—清洗、检查。
目前，钕铁硼生产厂家大多采用全自动磁场压机进行成型工序。成型所需的粉料在密封的储料仓中，当压机开始工作时，储料仓下方的阀门打开，同时振动器启动，粉料落入称量装置中进行称量，但是由于粉料黏度较高，经常有粉料无法落下的情况，生产现场操作人员频繁使用铁棍敲击储料仓，使粉料落下，这种操作方式严重影响了生产效率。
发明内容
本发明所要解决的技术问题是，提供一种能解决目前烧结钕铁硼压机普遍存在的储料仓放料不畅问题的烧结钕铁硼压机储料仓放料处理装置及方法。
本发明解决其技术问题所采用的技术方案是：
本发明之烧结钕铁硼压机储料仓放料处理装置，包括储料仓、密封仓、环形气管，所述储料仓位于密封仓中，所述环形气管上设有气孔，所述环形气管位于储料仓中，与位于储料仓下侧的通气孔相连，所述通气孔连接有一脉冲氮气气源。
进一步，所述环形气管为环形铜气管。
进一步，所述气孔为6-10个（优选8个），均布在环形气管上。
本发明之烧结钕铁硼压机储料仓放料处理方法，是：打开储料仓的阀门，启动脉冲氮气气源，环形气管的气孔喷出脉冲气流，将粉料冲散，使下料顺畅，处理过程保持储料仓中气压与密封仓气压一致。
利用本发明，能解决现有烧结钕铁硼压机存在的储料仓放料不畅的问题。
