Powder press with mechanical-hydraulic shuttle control

摘要

A powder press with mechanical-hydraulic shuttle control including a main press shaft, a control unit mounted on the powder press for converting rotational motion into translational motion, including a first actuator assembly; a second actuator assembly in fluid communication with the first actuator assembly; a shuttle assembly disposed at one end of the second actuator assembly; and a cardan shaft for transferring rotational motion of the main press shaft to the control unit. The control unit includes first and second shafts disposed in spaced relationship to each other; first and second wheels, each mounted on a respective one of the first and second shafts; a member interconnecting the first and second wheels in rotational engagement; and an adjustable cam member mounted on the second shaft and operatively engaging the first actuator assembly such that rotation of the main press shaft rotates the cardan shaft which, in turn, is coupled to the first shaft in the control unit. Rotation of the first shaft produces a corresponding rotation of the first wheel which, through the interconnecting member rotates the second wheel and shaft. The adjustable cam member mounted on the second shaft produces a linear motion in the first actuator assembly which produces a responsive motion in the second actuator assembly.
