钣制带轮近净成形技术及应用前景

钣制带轮以其精度高、节能、节材、动平衡好、无环境污染等特点,逐步淘汰铸/锻造后经机加工生产的其他形式的传统带轮,具有良好的社会效益和经济效益.钣制带轮是以金属板料为毛坯,经过落料、拉深等冲压工序制成圆筒状,然后将其装夹在带有顶压座的芯模上,使其随主轴一起旋转,通过若干不同齿形的旋压成形轮分别沿径向施加压力而成形.分析钣制带轮近净成形技术的研究现状,阐述应用近净成形技术生产带轮的优点,介绍带轮数控旋压设备的发展趋势,最后论述钣制带轮近净成形技术的发展以及应用情况.

The net-shape forming technology and application prospect of the belt pulley

The pulley produced by net-shape forming technology has the characteristics of high precision,energy-saving,material-saving, good dynamic equilibrium,no environmental pollution and so on;so it gradually takes the place of the traditional pulley,and brings good social and economic benefits.By the net-shape forming technology,metal sheet is used as a blank,the cylindrical cup is produced through blanking,deep drawing,and etc,and then the cup is clamped to a mandrel rotated together with the main spindle,the pulley is finally produced by several different spinning rollers,which apply the radial spinning forces to the cup in different positions.The current research of the net-shape forming technology of pulley,the advantages of utilizing the netshape forming technology to produce pulley,the development prospect of the CNC spinning machine for producing pulley,and the application status of the pulley net-shape forming technology are discussed.
