Description

A wireless pressure monitoring device

technical field

The invention relates to the technical field of molds, in particular to a wireless pressure monitoring device.

Background technique

Stamping operations use compressed gas, such as nitrogen cylinders, to move parts within the die assembly. A nitrogen gas cylinder can be installed in the upper mold of the mold assembly. Typically, the cylinders are piped together and form a piping system so that the system pressure can be easily changed. However, systems connected by plumbing include many joints, each of which increases the risk of leaks.

During punching operations, system operators do not always visually monitor pressure gauges during each setup cycle, whether or not such an operation is required. If parts are run at the incorrect nitrogen pressure, they will have difficulty meeting tolerance specifications. Typically, the upper die does not have electrical connections for any sensors. Wireless monitoring devices are needed to solve the above problems, and traditional electrically connected pressure sensors cannot always be placed at or in locations where pressure readings are required or possible. For example, while pressurized hoses may exist in difficult environments—such as moisture, rotation, and a lot of movement—such environments may be detrimental to sensor operation, maintenance, and use.

In view of the above, we propose a wireless pressure monitoring device to solve the above problems.
