Abstract
A die for stamping sheet metal comprises a first portion with a convex bead, a second portion with a concave channel, at least one accelerometer positioned near the concave channel. When a sheet metal is positioned between the first portion and the second portion, the first portion and the second portion are configured to be brought together so that the convex bead mates with the concave channel to apply a blank holding force (BHF) to the sheet metal to clamp the sheet metal. The at least one accelerometer measures a time domain parameter or profile or a frequency domain parameter or profile during the placement of the sheet metal.
Claims20
A die for stamping sheet metal, the die comprising:
- a first portion with a convex bead;
- a second portion with a concave channel;
- and
- at least one accelerometer positioned near the concave channel,
- wherein when a sheet metal is positioned between the first portion and the second portion, the first portion and the second portion are configured to be brought together so that the convex bead mates with the concave channel to apply a blank holding force (BHF) to the sheet metal to clamp the sheet metal, and wherein the at least one accelerometer measures a time domain parameter or profile or a frequency domain parameter or profile during placement of the sheet metal.
A die for stamping sheet metal, the die comprising:
- a first portion with a convex bead;
- a second portion with a concave channel;
- a bolster, the second portion being secured to the bolster;
- and
- at least one accelerometer positioned on the bolster,
- wherein when a sheet metal is positioned between the first portion and the second portion, the first portion and the second portion are configured to be brought together so that the convex bead mates with the concave channel to apply a blank holding force (BHF) to the sheet metal to clamp the sheet metal, and wherein the at least one accelerometer measures a time domain parameter or profile or a frequency domain parameter or profile during placement of the sheet metal.
A system for stamping sheet metal, the system comprising:
- a first portion with a convex bead;
- a second portion with a concave channel;
- a bolster, the second portion being secured to the bolster;
- a plurality of accelerometers positioned at least on the second portion and the bolster;
- and
- a processing unit that communicates with the plurality of accelerometers,
- wherein when a sheet metal is positioned between the first portion and the second portion, the first portion and the second portion are configured to be brought together so that the convex bead mates with the concave channel to apply a blank holding force (BHF) to the sheet metal to clamp the sheet metal, and wherein the plurality of accelerometers measures a time domain parameter or profile or a frequency domain parameter or profile during placement of the sheet metal that is communicated to the processing unit.
