ABSTRACT:
A revolving cam-type press includes a drive shaft supported by a crown and a middle plate, the drive shaft being adapted to be rotated by a drive device; a revolving cam fixedly mounted on the drive shaft; a fluctuating disk provided on an inclined surface of the revolving cam for converting a rotational output of the revolving cam into a reciprocal motion; sliders movably provided at an outer peripheral portion of the fluctuating disk for producing a pressing pressure; a plurality of fluctuation disk rotation-prevention pins extending through the fluctuating disk to be in parallel relationship to and in a concentric relationship to the drive shaft, the pins being fixedly secured at their one ends to a slider guide; and spherical bearings slidably mounted respectively on the other ends of the rotation prevention pins and engaged respectively in through holes formed through the fluctuating disk. A line passing through centers of the spherical bearings is disposed in a plane bisecting an intersection angle formed between an axis of the drive shaft and an axis of the fluctuating disk. With this construction, the rotation of the drive shaft is transmitted to the fluctuating disk at a uniform velocity, so that the transmission of torque between the drive shaft and the fluctuating disk is effected at a uniform velocity, thereby reciprocally moving the sliders without applying any external force to the slider.
