    • Disclosed is an improved cam unit (1) to be mounted to a stationary metal mold tool and a movable metal mold tool for use in effecting a required machining on a pressed plate article. It comprises a cam driver (10) to be fixed to the movable metal mold, a cam slider (2) to be driven by the cam driver (10) and a cam base (3) to be fixed to the stationary mold tool for supporting slidably the cam slider. It further comprises self-centering means (2a, 2b, 3a, 3e) on the sliding surfaces of the cam slider and the cam base. The self-centering means comprises the inverted-"V" shapes formed on the confronting surfaces of the counter sliding parts. Thanks to the self-centering means the cam unit is free of any decentering of the cam slider even if a significant wearing is caused between the sliding surfaces of the counter sliding parts.
    • 公开了一种改进的凸轮单元(1),其被安装到固定金属模具工具和可移动金属模具工具,用于在压板制品上进行所需的加工。 它包括固定在活动金属模具上的凸轮驱动器(10),由凸轮驱动器(10)驱动的凸轮滑块(2)和固定在固定模具上的凸轮基座(3) 滑动凸轮滑块。 它还包括在凸轮滑块和凸轮基座的滑动表面上的自对中装置(2a,2b,3a,3e)。 自对中装置包括形成在反向滑动部件的相对表面上的倒V形。 由于采用自定心装置,即使在相对滑动部件的滑动表面之间引起显着磨损,凸轮滑块也不会有任何偏心。
