磁心模板是对磁心进行按一定方向排列的模具,便于下一步把磁心反粘到胶布上然后进行穿线。采用这种工艺比过去人工穿板和磁心模条穿板机优越,同时也为今后小磁心穿板提供了方便。现将金属模板试制情况介绍如下: 一、对模板的要求和模板的结构模板按4096为单元制作,每块模板正面是4096个矩形孔填装磁心用,背面是和矩形孔对应的吸气圆孔。磁心的尺寸为:外径:Φ0.605±0.02 mm,内径:Φ0.4±0.015 mm,高度:0.215±0.015 mm。为了使磁心很好排列、落槽及粘贴,对模板提出如下几方面要求:
Core template is a magnetic core arranged in a certain direction of the mold, the next step to reverse the core anti-adhesive tape and then threading. Adopting this kind of technology is more superior than the manual wear plate and core die plate plate welder in the past, at the same time, it also provides convenience for the future small core wear plate. Now trial production of metal templates are as follows: First, the requirements of the template and the template structure Template 4096 for the production of each template front is 4096 rectangular hole filled with a magnetic core, the back is the rectangular hole and the corresponding suction circle hole. The size of the core is: Outer diameter: Φ0.605 ± 0.02 mm, Inner diameter: Φ0.4 ± 0.015 mm, Height: 0.215 ± 0.015 mm. In order to make the core well arranged, dropping and paste, the template made the following requirements:
