Abstract
A die assembly for use with a stamping die. The die assembly having a system for monitoring a gas pressure in the stamping die. The system including first and second piston-cylinder assemblies acting on a flag block wherein movement of the flag block corresponds to a pressure change. A sensor detects a movement of the flag block.
Claims18
A die assembly comprising:
- a first pressure source acting on a die component;
- a pressure monitoring system, including a first piston-cylinder assembly coupled to the first pressure source and a second piston-cylinder assembly coupled to a second pressure source;
- the first piston-cylinder assembly including a piston engaging a flag block and the second piston-cylinder assembly including a piston engaging the flag block;
- and
- a sensor, the sensor detects a movement of the flag block.

A die assembly comprising:
- a first pressure source acting on a die component in an upper die;
- a pressure monitoring system, including a die mount connected to the upper die;
- a first piston-cylinder assembly coupled to the first pressure source and supported by the die mount;
- a second pressure source;
- a second piston-cylinder assembly coupled to the second pressure source and supported by the die mount;
- a flag block positioned between the first piston-cylinder assembly and the second piston-cylinder assembly;
- the first piston-cylinder assembly engaging the flag block and the second piston-cylinder assembly engaging the flag block;
- and
- a sensor adjacent the flag block.
6 more elements
A die assembly comprising:
- an upper die and a lower die, at least one of the upper die and the lower die movable to position the upper die and the lower die in a closed position;
- a first pressure source acting on a die component in the upper die;
- a pressure monitoring system, including a die mount connected to the upper die;
- a first piston-cylinder assembly coupled to the first pressure source and supported by the die mount;
- a second pressure source;
- a second piston-cylinder assembly coupled to the second pressure source and supported by the die mount;
- a flag block moving laterally slidably mounted for lateral movement on the die mount between the first piston-cylinder assembly and the second piston-cylinder assembly;
- the first piston-cylinder assembly engaging the flag block and the second piston-cylinder assembly engaging the flag block;
- a U-shaped tuning flag attached to the flag block, with a base portion of the U-shaped tuning flag spaced from the flag block;
- a sensor mounted to the lower die and adjacent the flag block when the upper die and the lower die are in the closed position;
- and
- the sensor is a proximity sensor positioned adjacent the base portion of the U-shaped tuning flag and to sense lateral movement of the U-shaped tuning flag resulting from a pressure difference between the first pressure source and the second pressure source.
