Title:
DEVICE FOR DRIVING ROTARY CAM OF NEGATIVE ANGLE FORMING MOLD
Document Type and Number:
Japanese Patent JP3509810
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a device with which high-quality working is enabled and also impact is absorbed even when the impact is added to a rotary body by correctly determining the turn starting position and the turn terminal position of a cam follower arm and performing indentation molding by accurately positioning a turning cam in a turning device for turning the rotary body by the extension and contraction of a cylinder.
SOLUTION: This rotationally driving device for turning the rotary body by the extension and contraction of the cylinder 51 is constituted by providing the rotary body freely turnably by supporting supporting shafts which are respectively projected from both ends of the rotary body, fixing the center part of the cam follower arm 70 to the supporting shaft, connecting one end of the cam follower arm to the piston rod of the cylinder by interposing a guide plate 71 between them, carving a guide groove 72 which is made so as to turn the cam follower arm at a distance in the orthogonal direction to the direction of the stroke of the piston rod on the guide plate and fitting a cam follower 73 at the tip of the cam follower arm into the guide groove.
