如图1至图6所示,所述轴向开关磁阻电机转子硅钢块的成型方法,包括:
(a)提供一硅钢片盘100,其中所述硅钢片盘100具有内端部1001和外端部1002,及贯穿所述内端部1001和所述外端部1002的多个固定孔110,多个所述固定孔110沿着所述硅钢片盘100的周向等距间隔排列,并且相邻的两个所述固定孔110之间形成硅钢块120;
(b)提供多个齿棒200,逐一将多个所述齿棒200依次***于所述固定孔110;
(c)提供一固型组件300,将所述固型组件300固定于所述内端部1001和所述外端部1002上;
(d)沿着所述硅钢块120和所述固定孔110之间界定的切割位置进行切割,以获得组装转子的多个硅钢块120。
所述硅钢片盘100通过所述固定孔110分隔成多个形状一致且呈梯形的所述硅钢块120, 多个所述硅钢块120通过切割分离,并可对应组装成一转子,解决了现有技术中片材不易归类的问题,不仅成型方便快捷,还有效提升转子的成型效率。另外所述硅钢块120通过两侧的所述齿棒200进行周向相对施压,以在切割过程中消除所述硅钢块120周向的回弹应力,以及所述硅钢块120通过所述固型组件300进行径向相对施压,以在切割过程中消除所述硅钢块120径向的回弹应力,以使所述硅钢块120的四周得到固定,防止切割后的所述硅钢块120发生变形,进而保障产品形状的一致性,实现工业化批量生产。
如图1至图3所示,所述步骤(a)进一步包括:
(a1)藉由一冲压设备冲压硅钢片1000;
(a2)藉由一卷制设备并以相同角速度卷制冲压后的所述硅钢片1000,以形成所述硅钢片盘100。
所述硅钢片盘100是通过所述硅钢片1000卷绕成型,并在卷绕之前对所述硅钢片1000进行冲压,以形成所述固定孔110等,不仅成型方便快捷,并有利于开展工业化批量生产。所述硅钢片1000通过挂连接胶等以在卷制过程粘结于一体,并形成所述硅钢片盘100。
其中所述硅钢片盘100呈环形,其轴向尺寸较小,具有位于径向方向且相对的所述内端部1001和所述外端部1002,以及具有位于轴向方向且相对的上端部1003和下端部1004。
如图3所示,冲压后的所述硅钢片1000具有多个间隔排列的孔部1100,及位于相邻两个所述孔部110之间的基片1200,进而在所述步骤(a2)中,多个所述基片1200逐一卷制形成多个环形排列的所述硅钢块120,多个所述孔部1100逐一卷制形成多个环形排列,且与所述硅钢块120间隔设置的所述固定孔110。
具体地,冲压设备提供一冲头模,并在所述硅钢片1000上冲压,以使冲压后的所述硅钢片1000具有间隔设置的所述孔部1100和所述基片1200。其中所述孔部1100的形状保持一致,而所述基片1200的形状不一致,详细地说明,由于所述硅钢块120呈梯形,并且所述硅钢块120梯形顶部呈弧形凹槽,所述硅钢块120梯形底部呈凸起,可见形成所述硅钢块120的多层所述基片1200,其以宽度渐大的方式沿着梯形高度方向(即从所述内端部1001至外端部1002方向)排列,因此所述基片1200的形状不一致。
进一步说明,以五个数量的所述硅钢块120为例,其中所述固定孔110的数量与所述硅钢块120的数量一致,并依次间隔设置。在所述步骤(a1)中,所述冲压设备以第一宽度连续冲压所述硅钢片1000六次,以在所述硅钢片1000上形成五个所述间隔设置地孔部1100,以使所述硅钢片1000上形成第一宽度的五个所述基片1200,之后在所述步骤(a2)中,所述卷制设备将五个所述基片1200卷制,并使五个所述基片1200呈依次连接的环形排列,同 时所述冲压设备以第二宽度连续所述硅钢片1000五次,以在所述硅钢片1000上形成五个所述间隔设置的孔部1100,以使所述硅钢片1000上形成第二宽度的五个所述基片1200,之后利用卷制设备将五个第二宽度的基片1200卷制于五个第一宽度的基片1200外,并一一对应,如此往复,以形成如图2所示的所述硅钢片盘100。
更进一步说明,所述第二宽度大于所述第一宽度,以使在每个所述硅钢块120结构中,多个所述基片1200沿着所述硅钢片盘100径向且以宽度渐大的方式被叠合形成所述硅钢块120。
需要说明的是,所述卷制设备并以相同角速度卷制冲压后的所述硅钢片1000,以使每个所述硅钢块120的多个所述基片1200能够一一对应,防止位移偏差而影响所述硅钢块120的成型效果。
如图2和图3所示,所述孔部1100位于所述硅钢片1000上下侧的中间位置,即形成的所述固定孔110位于所述上端部1003和所述下端部1004的中间位置,并且所述固定孔110的宽度与所述硅钢片盘100厚度之比大于等于1/2,在保障所述固定孔110不影响所述硅钢片盘100结构稳定的情况下,增加了所述齿棒200与所述硅钢块120的接触面积,进而提升所述齿棒200对所述硅钢块120的压力,进一步避免所述硅钢块120在切割过程中出现变形。其中所述固定孔110的宽度指的是所述固定孔110在所述硅钢片盘100轴向上的尺寸,所述上端部1003和所述下端部1004之间界定了所述硅钢片盘100厚度。
如图2和图3所示,所述基片1200的左右两侧分别向内凹陷形成限位部1210,进而在每个所述硅钢块120的结构中,多个所述基片1200两侧的限位部1210分别形成分设在所述硅钢块120两侧的限位槽121。
两个所述限位槽121沿着所述硅钢片盘100周向,且分设于所述硅钢块120的两侧。其中所述硅钢块120利用限位槽121固定于转子架上,以防止所述硅钢块120在所述转子架上发生轴向移动。而所述限位部1210是与所述孔部1100一起成型的,并利用卷制形成分设在所述硅钢块120周向两侧的限位槽121,使得所述限位槽121成型更加方便快捷,相对于在所述硅钢块120成型后再冲压形成所述限位槽121来说,保证了所述硅钢块120整体形成的可靠性,进而避免影响产品的一致性。
具体地,参考图3,所述限位部1210与所述孔部1100相连通,并且每个所述孔部1100的两侧分别对应一所述限位部1210,可见所述冲头模对应一所述孔部1100及分设在所述孔部1100两侧的所述限位部1210,即所述冲头模在所述硅钢片1000上冲压后,形成如图3所述的孔部1100及分设在所述孔部1100两侧的所述限位部1210,而在后续卷制过程中,所 述限位部1210就形成了所述设置在所述硅钢块120上的限位槽121。可见所述限位槽121从所述内端部1001延伸至所述外端部1002,即贯穿每个所述基片1200参考图2。
更具体地,所述限位部1210呈半圆形,且位于所述基片1200的中间位置,可见成型后的所述限位槽121位于所述硅钢块120的中间位置。
如图2所示,所述硅钢片盘100还具有上端部1003和下端部1004,所述上端部1003和/或所述下端部1004上设置有与所述切割位置相对的导向槽130,进而在所述步骤(d)中,沿着所述导向槽130进行切割。通过设置所述导向槽130,实现切割后所述硅钢块120保持一致性,进而开展工业化批量生产。
所述导向槽130从所述内端部1001延伸至所述外端部1002,在一个实施例中,每个所述硅钢块120分别对应四个所述导向槽130,其中两个所述导向槽130分别对应所述硅钢块120的左侧,且分设于所述上端部1003和下端部1004上,另两个所述导向槽130分别对应所述硅钢块120的右侧,且分设于所述上端部1003和下端部1004上。通过在所述上端部1003和所述下端部1004上均设置导向槽130,因此无论硅钢片盘100如何定位,均可沿着所述上端部1003和所述下端部1004上的所述导向槽130进行切割。
在另一个实施例中,所述硅钢块120分别对应两个所述导向槽130,两个所述导向槽130分别对应所述硅钢块120的左右两侧,且均位于所述上端部1003上,因此所述硅钢片盘100定位时。所述上端部1003朝上设置,以便通过所述上端部1003的所述导向槽130进行切割。
如图2和图3所示,所述硅钢片1000的上侧和/或下侧凹陷形成多个导向部1300,所述导向部1300与所述切割位置相对,进而在所述步骤(a2)中,多个所述导向部1300逐一卷制形成暴露在所述上端部1003和/或所述下端部1004的导向槽130。
所述导向部1300可分别与所述限位部1210和所述孔部1100一起成型,并利用卷制形成暴露在所述上端部1003和/或所述下端部1004的导向槽130。使得所述导向槽130成型更加方便快捷,并保证一致性。具体地,每个所述冲头模分别对应一所述孔部1100,两个位于所述孔部1100两侧的所述限位部1210,以及四个分设在所述孔部1100两侧的所述导向部1300,即当所述冲压模对所述硅钢片1000进行一次冲压后,所述硅钢片1000形成相对的一所述孔部1100,两所述限位部1210和四个所述导向部1300。
参考图2,所述切割位置指的是所述硅钢块120与所述固定孔110之间的连接处,具体对应所述硅钢块120的左右侧边缘,即沿着所述硅钢块120的左右边缘进行切割,以获得切割后的所述硅钢块120。参考图3,在所述硅钢片1000上冲压形成,且与所述切割位置相对的所述导向部1300中,所述导向部1300位于所述基片1200的左右边缘,其横截面可呈方 形或圆形等,在此不受限制。
如图2所示,在每个所述硅钢块120结构中,多个所述基片1200沿着所述硅钢片盘100径向且以宽度渐大地方式被叠合形成所述硅钢块120,并且所述基片1200呈弧形结构,所述硅钢块120的内侧呈弧形凹槽,所述硅钢块120的外侧呈弧形凸起。
如图2和图4所示,所述齿棒200与所述固定孔110的横截面形状一致,例如均呈长方形,当所述齿棒200***于所述固定孔110后,以对邻近的所述硅钢块120施加压力,防止所述个硅钢块120因切割而变形。所述齿棒200可人工或自动实现其与所述硅钢片盘100的装配。
具体地,所述齿棒200分别与所述内端部1001和所述外端部1002齐平,以便于所述固型组件300对两者的固定。其中所述齿棒200一端呈弧形凹槽,其与所述内端部1001齐平,所述齿棒200的另一端呈弧形凸部或者大致水平,以与所述外端部1002齐平。
其中所述固型组件300对所述内端部1001和所述外端部1002的固定,可手动或自动完成,例如当所述齿棒200与所述硅钢片盘100装配完成后,利用机械手等将固型组件300到所述内端部1001和所述外端部1002上,还通过输送带等提供移动功能,进而实现自动化操作,以提升成型效率。
如图5所示,所述固型组件300包括一内固型件310和一外固型件320,进而所述步骤(c)进一步包括:
(c1)将所述内固型件310固定于所述内端部1001上;
(c2)将所述外固型件320固定于所述外端部1002上。
所述内固型件310呈环形,用于对所述内端部1001施加压力,所述外固型件320也可呈环形,用于对所述外端部1002施加压力,进而对所述硅钢块120的径向施加压力,以在切割过程中消除所述硅钢块120径向的回弹应力,进而保障产品形状的一致性,实现工业化批量生产。另外所述内固型件310和所述外固型件320同时对所述齿棒200进行固定,保证了所述齿棒200对所述硅钢块120的周向施压。
继续参考图5,所述外固型件320包括两个卡箍321,进而所述步骤(c2)进一步包括:
将两个所述卡箍321箍紧于所述外端部1002上,并通过紧固件322锁紧。
在所述步骤(d)中,可利用激光或线切割的方式对所述硅钢片盘100进行切割。
以激光切割为例,当完成所述固型组件300与所述硅钢片盘100装配后,输送至激光切割设备处,沿着所述导向槽130进行切割,以获得组装成同一转子的多个硅钢块120。
在所述步骤(d)之后进一步包括以下步骤:
对同一所述硅钢片盘100上的多个所述硅钢块120进行下料,并输送至所述转子成型处且与转子架进行组装,以形成转子。
对所述硅钢块120进行下料包括:取下所述固型组件300,以解除所述固定组件300对所述硅钢片盘100的径向施力,此时切割后的所述硅钢块120独立存在,可进行相应的下料。
其中被取下的所述固型组件300和所述齿棒200可进行循环使用。
可见,同一所述硅钢片盘100上的多个所述硅钢块120,其可对应组装呈一转子,因此可根据转子的要求(包括硅钢块120数量和尺寸等)设计和制定所述硅钢片盘100结构,进而便于所述硅钢块120的归类和整理,提升转子的成型效率。
综上所述,所述硅钢片盘100通过所述固定孔110分隔成多个形状一致且呈梯形的所述硅钢块120,多个所述硅钢块120通过切割分离,并可对应组装成一转子,解决了现有技术中片材不易归类的问题,不仅成型方便快捷,还有效提升转子的成型效率。另外所述硅钢块120通过两侧的所述齿棒200进行周向相对施压,以在切割过程中消除所述硅钢块120周向的回弹应力,以及所述硅钢块120通过所述固型组件300进行径向相对施压,以在切割过程中消除所述硅钢块120径向的回弹应力,以使所述硅钢块120的四周得到固定,防止切割后的所述硅钢块120发生变形,进而保障产品形状的一致性,实现工业化批量生产。

所述硅钢片盘100通过所述固定孔110分隔成多个形状一致且呈梯形的所述硅钢块120,多个所述硅钢块120通过切割分离,并可对应组装成一转子,解决了现有技术中片材不易归类的问题,不仅成型方便快捷,还有效提升转子的成型效率。另外所述硅钢块120通过两侧的所述齿棒200进行周向相对施压,以在切割过程中消除所述硅钢块120周向的回弹应力,以及所述硅钢块120通过所述固型组件300进行径向相对施压,以在切割过程中消除所述硅钢块120径向的回弹应力,以使所述硅钢块120的四周得到固定,防止切割后的所述硅钢块120发生变形,进而保障产品形状的一致性,实现工业化批量生产。
如图2和图6所示,所述硅钢块120呈梯形,所述硅钢块120由多个不同宽度的基片1200 沿梯形高度方向堆叠而成。所述基片1200呈弧形结构,所述硅钢块120梯形底部呈弧形凸起,所述硅钢块120梯形顶部呈弧形凹槽。以与转子架组装后,形成片状的转子(即轴向尺寸小),以适应轴向开关磁阻电机。在转子结构中,多个基片1200的排列方向与转子的径向保持一致。
如图2和图6所示,所述硅钢块120两侧的限位槽121,所述限位槽121分别贯穿每个所述基片1200。其中所述硅钢块120利用限位槽121固定于转子架上,以防止所述硅钢块120在所述转子架上发生轴向移动。
如图2所示,所述硅钢片盘100还具有上端部1003和下端部1004,所述上端部1003和/或所述下端部1004上设置有导向槽130,所述导向槽130与所述硅钢块120和所述固定孔110之间界定的切割位置相对。
通过设置所述导向槽130,实现切割后所述硅钢块120保持一致性,进而开展工业化批量生产。
所述导向槽130从所述内端部1001延伸至所述外端部1002,在一个实施例中,每个所述硅钢块120分别对应四个所述导向槽130,其中两个所述导向槽130分别对应所述硅钢块120的左侧,且分设于所述上端部1003和下端部1004上,另两个所述导向槽130分别对应所述硅钢块120的右侧,且分设于所述上端部1003和下端部1004上。通过在所述上端部1003和所述下端部1004上均设置导向槽130,因此无论硅钢片盘100如何定位,均可沿着所述上端部1003和所述下端部1004上的所述导向槽130进行切割。
在另一个实施例中,所述硅钢块120分别对应两个所述导向槽130,两个所述导向槽130分别对应所述硅钢块120的左右两侧,且均位于所述上端部1003上,因此所述硅钢片盘100定位时。所述上端部1003朝上设置,以便通过所述上端部1003的所述导向槽130进行切割。
如图2和图4所示,所述齿棒200一端呈弧形凹槽,其与所述内端部1001齐平,所述齿棒200的另一端呈弧形凸部或者大致水平,以与所述外端部1002齐平。
所述齿棒200与所述固定孔110的横截面形状一致,例如均呈长方形,当所述齿棒200***于所述固定孔110后,以对邻近的所述硅钢块120施加压力,防止所述个硅钢块120因切割而变形。并且所述齿棒200的两端分别与所述内端部1001和所述外端部1002齐平,以使所述固型组件300对所述齿棒200同时进行径向固定,以保证所述齿棒200对所述硅钢块120施压。
如图5所示,所述固型组件300包括一内固型件310和一外固型件320,所述内固型件310固定于所述内端部1001上,所述外固型件320固定于所述外端部1002上。
具体地,所述外固型件320包括两个卡箍321,两个所述卡箍321箍紧于所述外端部1002上,并通过锁紧件322锁紧。
如图2所示,所述固定孔110位于所述上端部1003和所述下端部1004的中间位置,并且所述固定孔110的宽度与所述硅钢片盘100厚度之比大于等于1/2。
在保障所述固定孔110不影响所述硅钢片盘100结构稳定的情况下,增加了所述齿棒200与所述硅钢块120的接触面积,进而提升所述齿棒200对所述硅钢块120的压力,进一步避免所述硅钢块120在切割过程中出现变形。其中所述固定孔110的宽度指的是所述固定孔110在所述硅钢片盘100轴向上的尺寸,所述上端部1003和所述下端部1004之间界定了所述硅钢片盘100厚度。
综上所述,所述硅钢片盘100通过所述固定孔110分隔成多个形状一致且呈梯形的所述硅钢块120,多个所述硅钢块120通过切割分离,并可对应组装成一转子,解决了现有技术中片材不易归类的问题,不仅成型方便快捷,还有效提升转子的成型效率。另外所述硅钢块120通过两侧的所述齿棒200进行周向相对施压,以在切割过程中消除所述硅钢块120周向的回弹应力,以及所述硅钢块120通过所述固型组件300进行径向相对施压,以在切割过程中消除所述硅钢块120径向的回弹应力,以使所述硅钢块120的四周得到固定,防止切割后的所述硅钢块120发生变形,进而保障产品形状的一致性,实现工业化批量生产。
