皮带轮是重要的机械传动零件,它应用于汽车、拖拉机、农用机械、食品机械、家用电器、工业自动化系统和纺织机械等各种机械传动设备上,用途十分广泛。在七十年代,国内外已出现了用钢板经冲压而制作的皮带轮:即将钢板用模具冲压成两个同样的碟形件,并将它们背靠背地用铆接或焊接成为一体,形成一个单槽带轮。由于是分体结构,产品精度低,也仅局限于加工单“V”字槽皮带轮。但此加工方法与原车削加工的皮带轮相比已是一个飞跃,是节约原材料、节约能源的一个典型产品。进入八十年代,德国、日本、美国等经过多年的探索与开发,研制出旋压皮带轮新工艺和专用设备,为皮带轮加工的升级换代起了积极 Pulley is an important mechanical transmission parts, it is used in a variety of mechanical transmission equipment such as automobiles, tractors, agricultural machinery, food machinery, household appliances, industrial automation systems and textile machinery, a wide range of uses. In the 1970s, steel belts were stamped and produced at home and abroad. Pulleys were manufactured by stamping the steel plate into two identical discs and stitching or welding them back to back to form a single groove wheel. Because it is a split structure, the product accuracy is low, it is only limited to processing single “V ” slot pulley. However, this processing method is compared with the original turning pulley pulley is a leap forward, saving raw materials, energy conservation is a typical product. Into the eighties, Germany, Japan, the United States, after many years of exploration and development, developed a new spinning wheel technology and special equipment for the upgrading of the pulley processing has played a positive
