SSE, SSEV, SSEA

A Swing Clamp of unsurpassed strength and reliability

Diagram

These units are mounted on the Press Slide and swing into position through slot in the die. The swing-in action of the Tie-Rod and Clamping are controlled automatically, and occur in series. Once the unit is clamped, through its mechanical toggle system, it becomes completely hydraulic independent and all line pressures go to zero.

While clamped, the unit monitors clamp force and thereby can detect such irregularities as tool failure, die shoe compression, tie rod failure, etc. A drop in clamp force beyond a pre-set limit will result in an immediate press shut-down.

Finally, due to its mechanically rigid clamp action, the tool remains positively fixed to ensure the highest possible level of stamping precision.

Safety Features - Clamp Force Monitoring

A safety circuit is monitored by Optima's internal "Activator" assembly. Any reduction in clamp force, past a pre-set limit, automatically trips a limit switch and results in a press shut-down.

Limit Switch: Switch Rating 5A/250V
  Inductive 3A/30V
  Resistive 3A/30V

If a water and oil tight installation is desired, we would recommend that limit switch fittings be used in conjunction with a protective hose.
