Temperature mapping apparatus and method

摘要

An apparatus 10 for determining a temperature map across at least part of a blank 100 having first and second surfaces. The apparatus comprises a temperature measuring device 20A, such as a pyrometer or a thermocouple, for measuring the temperature of a first spot S1 on the blank 100 and for producing an output temperature signal. The apparatus also comprises a thermal camera 30 for taking a thermal image of the blank 100 and for producing a thermal image output. A transmitter 40A is provided for transmitting the output temperature signal from the temperature measuring device 20A. An adjuster 50 is connected to receive the thermal image output from the thermal camera 30 and to receive the output temperature signal from the transmitter 40A and for adjusting the thermal image output of the thermal camera 30 in accordance with the output temperature signal from the temperature measuring device 20A to create the temperature map. The blank may be a sheet metal blank used in a forming process.
