[0002] In metal pressure processing, the metal is forced through the die under the action of external force, the metal cross-sectional area is compressed, and the technical processing method of obtaining the required cross-sectional area shape and size is called metal wire drawing process. The tool that changes its shape and size is called wire drawing die.

[0003] Nowadays, the inspection of metal drawing is done manually with a vernier caliper. The two detection ends of the vernier caliper need to be clamped on the outside of the metal drawing for measurement. However, when it is necessary to measure the diameter of a thicker metal drawing wire, the size of the measuring claws of the vernier caliper is limited and cannot be effectively measured. If a ruler is used for measurement, it is impossible to accurately align the axis of the metal drawing wire, which will cause errors in the measured size, seriously affecting the accuracy of size detection.
