一、铁芯自动叠装技术铁芯是机电产品的重要部件之一,一般是由厚为0.35、0.5毫米的高导磁率硅钢片制成,重量约占产品重量的25～30％。现有的各种铁芯加工工艺,所得到的仅仅是定子、转子冲片,虽然在多工位级进模中可以用附加导笼和称重法、片数控制法对冲片进行预叠装,但仍然属于模具外的铁芯叠装,而操作机械、单调的理片工序并没有完全排除,冲片与冲片之间的定位误差无法消除,使铁芯的整齐度受到影响。
First, the automatic core stack technology Iron core is one of the important components of mechanical and electrical products, usually made of high permeability silicon steel 0.35, 0.5 mm thick, weighing about 25 to 30% by weight of the product. The existing variety of iron core processing technology, the only obtained stator, rotor punching, although in the multi-stage progressive die can be used with additional guide cage and weighing method, sheet number control method of prestamped sheet , But still belong to the mold core stack, and the operation of machinery, monotonous process of the chip is not completely ruled out, the positioning error between the punch and the punch can not be eliminated, so that the uniformity of the core affected.
