我厂是航空工业部微型汽车用发电机的定点生产厂,同时也大量生产东风140型汽车配套用的发电机.随着汽车产量及销售量的不断增加,发电机中,定子铁芯材料硅钢片的消耗量是可观的.传统的定子铁芯生产方式是把板料先冲成带若干内齿槽的圆片,然后再叠压而成.这种加工方法最大缺点是:材料利用率低;工艺落后;效率不高.因此发电机整机的生产成本也不易下降.据有关资料报导,在七十年代英国、日本、西德、美国、瑞士等国家先后出现了卷带式定子铁芯制造工艺,并已大量用于生产.例如英国Lucas公司使用西德Burderer公司的高速冲床,带料130mm宽,1mm厚,它平行地向冲床自动送料冲槽(齿数为652
I plant is the ministry of aviation industry minicar generator sentinel plants, but also a large number of production Dongfeng 140-type vehicle with a generator. With the continuous increase in automobile production and sales, the generator, the stator core material silicon steel The consumption of the film is considerable.Traditional stator core production method is to first blanketed sheet into a number of internal toothed disc, and then laminated. The biggest drawback of this processing method is: low material utilization ; Technology behind; efficiency is not high, so the generator production costs are not easy to fall.According to the information reported in the seventies Britain, Japan, West Germany, the United States, Switzerland and other countries have appeared in the winding stator core For example, Lucas in the United Kingdom uses a high-speed punch press from Burderer, West Germany, with a strip width of 130 mm and a thickness of 1 mm, which is fed parallel to the punch (652 teeth
