GUIDE CAM MECHANISM FOR PREVENTING INTERFERENCE

摘要

PROBLEM TO BE SOLVED: To solve the problem that the space of a die is extended and machining is complicated to cause cost increase in a conventional double cam and a rotary cam with respect to a guide cam mechanism for preventing interference. SOLUTION: The guide cam 3 on the side of a die having a curved surface for bending a workpiece 2 is made into the guide cam mechanism 1 for preventing interference which is made savable by connecting a shaft 4 which is horizontally installed in the lower part of this guide cam 3 and with which the guide cam is pivotally supported and the other end part of a link plate one end of which is freely rotatably supported with a lower die and oscillated and providing a device 6 for moving forward and backward for making the shaft move forward and backward in parallel to the link plate 5 for oscillating the shaft by engaging with the shaft 4.
