UnclampSwing■ Features① Compact size came out from simplified eccentric clamp mechanism,
bearing high power along with durability and impact-resistance.
② At clamping, air cylinder output is enlarged by eccentric clamp
mechanism, and it gives a large pull-up force and holding force toclamp rod. The model TNA□A and TNA□B are equipped with hard
pull-up spring inside air cylinder. Thus the die holding force is kept
even when air supply is cut off. Even when press machine is not inuse, die is securely clamped.
③ Position indicator on the body presents clamp / unclamp / swing
conditions.
④ The limit switches for clamp and unclamp detection are provided to setup the safety interlock.
⑤ All of mechanisms are based on maintenance-free concept.
