Description

Technical Field

[0001] This utility model relates to the field of mold steel testing technology, and in particular to a testing device for the thermal fatigue resistance of mold steel. Background Technology

[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing, the precision and output of the product, and the production cost. In addition to reasonable structural design and machining accuracy, the quality and service life of the mold are mainly affected by the mold material and heat treatment.

[0003] In existing technologies, when testing the thermal fatigue resistance of mold steel, workers need to remove the mold for testing. Since the mold steel reaches a high temperature during thermal fatigue testing, removing it for testing is inconvenient and poses safety hazards. In order to improve the accuracy of testing the thermal fatigue resistance of mold steel, traditional methods use handheld magnifying glasses for observation, but this is cumbersome, time-consuming, and labor-intensive. To solve this problem, a testing device for the thermal fatigue resistance of mold steel is proposed. Utility Model Content
