本发明涉及一种硅钢片铁芯用自动叠装系统,托板、上料单元、精定位单元、叠装单元、抓取单元,所述上料单元有一个,位于中部位置,所述精定位单元一共有两个,分别位于上料单元的两侧,所述叠装单元一共有两个,分别位于两个精定位单元的两侧,从而使得整个自动叠装系统由中间向两侧方向均依次为上料单元、精定位单元、叠装单元。本发明的优点在于:通过对上料单元、精定位单元、叠装单元的数量及排布位置进行重新设计,采用由中间向两侧供料的方式,使得两侧的上料顺序均独立运行,不存在相互干涉的风险,确保单侧的上料顺序的顺利进行,相对应的也就降低了程序设计的复杂程度,减轻了设计人员的工作强度。

对商用50W330型无取向硅钢成品在930℃下保温2 h固溶并以不同方式冷却处理,利用磁性检测仪检测分析了处理前后的磁感和铁损变化,应用光学显微镜、扫描电子显微镜、X射线衍射仪观测分析了显微组织结构的演变。考察了平均晶粒尺寸、织构组分比及第二相粒子状态对磁性能的影响规律,结果表明:固溶处理前后平均晶粒尺寸的变化对硅钢磁性能的影响非常显著;当平均晶粒尺寸相差不大时,织构组分比[Goss+{100}]/{111}越大,磁感会越高;固溶处理会将细小弥散的第二相粒子重新回溶到基体中,减小了其对磁畴壁的钉扎作用,铁损随之下降。 The commercial 50W330 non-oriented silicon steel samples were heat treated at 930℃ for 2 h and cooled in different ways,then the iron loss and the magnetic induction of the samples before and after solution treatment were measured with a magnetic detector.The evolution of microstructural texture was analyzed by optical microscopy,scanning electron microscopy and X-ray diffractometry.The effects of average grain size,texture composition ratio and the second phase particles on the magnetic propert...
