压力机数控化改造设计

Retrofitting Press with NC System

对曲轴式压力机的数控化改造设计原理和方法作了分析，并对数控化改造的二坐标工作台、板料夹钳机构、控制系统、冲压与送料同步控制功能、小模具冲制大孔功能、工件二次定位功能等设计方法作了详细介绍。

An analysis is made on designing principleand method to retrofit a crank type press into a NCpress. It introduces clearly the design processes of 2 axis worktable, sheet metal clamping device, controlsystem and functions of synchro controlling punching& feeding, big hole punched with small punch, worpiece 2nd. positioning, etc.
