Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to an online heat treatment device for fasteners. Background Technology

[0002] Threaded screws are a type of fastener. Fasteners are a class of mechanical parts used for fastening, and their applications are extremely wide. Various mechanical equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, household appliances, handicrafts and gifts, locks, etc., all require thousands of different specifications of fasteners for fastening connections and structural links. Common fasteners are among the most widely used and numerous common mechanical parts.

[0003] The heat treatment process for threaded screws can alter the internal microstructure of the material, thereby enabling the threaded screws to acquire the desired performance and quality. Double-end quenching is required during the heat treatment of threaded screws. Currently, when quenching both ends of threaded screws, the dimensions are typically measured manually first, and then quenched end-by-end using a high-frequency quenching machine. This method is inefficient, and the uneven heating of the threaded screw ends affects the quenching effect.
