Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting tool detection, and specifically to a hardness detection device for die-cutting tools used in printing. Background Art

[0002] Die-cutting tools for printing are mainly used to die-cut various printing materials to achieve the expected shape and size. They are indispensable tools in the printing industry. Die-cutting tools are sheet materials made of steel with blades at the top for making die-cutting plates, having high strength and wear resistance. The cutting edges are precisely processed to ensure die-cutting accuracy and cut quality, and are suitable for different printing materials and die-cutting requirements.

[0003] After the die-cutting tool is manufactured, it is necessary to detect the hardness of the die-cutting tool to prevent insufficient hardness of the die-cutting tool from affecting subsequent normal production. Existing die-cutting tool hardness detections are usually completed by hardness testers, which cannot fix and detect multiple groups of die-cutting tools at the same time. When detecting the hardness of different positions of the die-cutting tool, it is necessary to move the die-cutting tool or the punch back and forth, and the detection operation is relatively inconvenient.
