最近几年汽车行驶速度越来越高,有的达到每小时250公里,带拖车的速度也已达到每小时200公里以上,对车轮提出较高要求。汽车车轮由轮辋和轮辐组成,而轮辋和轮辐又根据需要分成各种形式。在批量较大时,可用有较高产量的自动线生产。载重汽车、拖拉机和掘土机等车轮的生产,在小批生产时可用旋压机进行旋压成形。下面着重介绍旋压工艺和旋压机床。 In recent years, cars are getting faster and higher, and some reach 250 kilometers an hour. The speed of carrying trailers has reached more than 200 kilometers an hour, putting higher demands on the wheels. Car wheels consist of rims and spokes, and rims and spokes are divided into various forms as needed. In the larger batch, available with higher yield automatic line production. The production of wheels for trucks, tractors and earthmoving mills is available for spin-forming in small batch production. The following focuses on the spinning process and spinning machine.
