Y 系列三相异步电动机是全国统一设计的新产品,它有很多数据是按IEC 国际标准设计的。其风罩结构的主要特点是通风孔由许多个8×8的小方形孔整齐排列而成,具有刚性好、外形美观和使用安全等特点。但是,小方形孔的孔距小,尺寸紧凑,工艺要求高,所以风罩冲制小方形通风孔就成了Y 系列电机生产中的难点之一。1.工艺方案Y90电动机风罩用1.2毫米厚的08F 冷轧钢板拉伸而成。其直径为φ173、高90,通风孔由116个8×8小方形孔和一个φ8孔组成,纵横筋条宽度均为2毫米,要求小方
Y series three-phase asynchronous motor is the national unified design new product, it has a lot of data is according to IEC international standard design. The main feature of the windshield structure is that the ventilation hole is made up of numerous 8 × 8 small square holes arranged neatly with good rigidity, beautiful appearance and safe use. However, the small square hole hole pitch, compact size, high process requirements, so the hood of the small square vents punched Y series motor has become one of the difficulties. 1. Technology program Y90 motor hood with 1.2 mm thick 08F cold-rolled steel sheet made. Its diameter is φ173, height 90, ventilation hole consists of 116 8 × 8 small square hole and a φ8 hole, vertical and horizontal ribs width of 2 mm, requires small side
