本实用新型涉及钕铁硼布粉压模技术领域，具体地说是一种使用方便、产品合格率高、工作效率高的钕铁硼磁柱成型模具。 The utility model relates to the technical field of neodymium-iron-boron cloth powder pressing molds, in particular to an neodymium-iron-boron magnetic column forming mold which is easy to use, has high product qualification rate and high work efficiency.
背景技术 Background technique
众所周知，钕铁硼磁性材料是钕、氧化铁等的合金，又称磁钢，由于其优异的磁性能而被称为“磁王”，钕铁硼因其高磁能、高矫顽力和高能量密度的性能，使钕铁硼永磁材料在现代工业和电子技术中获得了广泛应用，从而实现仪器、仪表、电机等设备的小型化、轻量化、薄型化，具有性价比高，机械特性好等优点。 As we all know, NdFeB magnetic materials are alloys of neodymium, iron oxide, etc., also known as magnets. The performance of density makes NdFeB permanent magnet materials widely used in modern industry and electronic technology, so as to realize the miniaturization, light weight and thinning of instruments, meters, motors and other equipment, with high cost performance and good mechanical characteristics. advantage.
在钕铁硼磁柱的制作过程中，氢破研磨制粉后的粉料需要进行压制成型过程，即将粉料倒置在磁柱成型模具内进行压制，目前，钕铁硼手动磁柱成型模具，设有成型槽和成型压头，成型槽上的内底面上设有若干个半圆形凹槽，与之对应的成型压头上设有半圆形凹槽，成型槽与成型压头压合后对应的半圆形凹槽处结合形成圆柱形模腔，在圆柱形的钕铁硼成型过程中，首先将称量好的粉料导入模具中，然后摇动模具，用挂粉板刮平再进行压制，由于成型凹槽内低端设有半圆形的凹槽，由于底端设有弧面，将粉体倒入模具时，边角很容易产生空隙，同时由于粉体自身的流动性很差，容易造成底粉有“搭桥”现象，加大各圆柱之间的质量误差，产品的合格率降低，同时由于圆柱形钕铁硼在成型槽内压坯成型后从模具中取出时，圆柱形压坯料不结实极易松散，就会存在取出不方便、磕边掉角等不足。 In the production process of NdFeB magnetic column, the powder after hydrogen crushing and grinding needs to be pressed and formed, that is, the powder is inverted in the magnetic column forming mold for pressing. At present, the NdFeB manual magnetic column forming mold, There are forming grooves and forming pressure heads. There are several semicircular grooves on the inner bottom surface of the forming grooves. The corresponding forming pressure heads are provided with semicircular grooves. The forming grooves are pressed together with the forming pressure heads. Finally, the corresponding semicircular grooves are combined to form a cylindrical mold cavity. During the molding process of the cylindrical NdFeB, firstly, the weighed powder is introduced into the mold, then the mold is shaken, and then the mold is scraped with a powder hanging board. For pressing, because the lower end of the forming groove is provided with a semicircular groove, and because the bottom end is provided with an arc surface, when the powder is poured into the mold, it is easy to generate gaps at the corners, and at the same time, due to the fluidity of the powder itself Very poor, it is easy to cause the phenomenon of "bridge" of the base powder, increase the quality error between the cylinders, and reduce the qualified rate of the product. Cylindrical compacts are weak and easy to loosen, and there will be disadvantages such as inconvenient removal, knocked edges and corners.
