Aerial Cam Unit VALCAM

Reliability by increased rigidity and durability testing
Distortion has been reduced by 40% compared to the conventional cam units by reviewing the basic design and optimizing the shape by using CAE. Rigidity has been greatly increased without increasing the size or changing the material. In addition, an impact absorbing structure suitable for servo press machines has been adopted. This allows the impact force generated when the press ascends to be controlled. Durability laboratory tests have been repeatedly conducted in our servo press machine to ensure safety and reliability.

Reduction in size for space saving
46mm is the smallest in its class and this has been determined by minimizing the cam width so that a retainer having a shank diameter of h 13mm can be installed. The processing of adjacent cam piercing and installation in tight spaces are easily obtained. Even though the overall length of the cam is shortened, the working force, return force and stroke are equal or better in performance than the conventional cam units. This substantially reduces the area occupied by the cam unit in a die, thus downsizing the die and reducing the number of processes.

Prevention of sticking with increased return force
To prevent cam from sticking on a panel, which is a problem in High Strength Steel processing, the return force has been increased by 33% compared to the conventional cam units in the coil spring type. In the gas spring type, the return force has been strengthened 10% more than the maximum working force. Moreover, coil and gas spring mounting configurations are interchangeable allowing for increased return force when required.
