Description

Technical Field

[0001] This utility model relates to the field of annealing equipment, specifically a bright annealing equipment for the production of stainless steel seamless pipes. Background Technology

[0002] Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. In a broader sense, annealing is a heat treatment process for materials, including both metallic and non-metallic materials.

[0003] Bright annealing involves annealing metal parts under a specific gas concentration to ensure a bright outer surface. However, existing bright annealing equipment uses conveyor rollers to transport parts, requiring multiple power sources for operation, resulting in a complex structure and making subsequent maintenance extremely inconvenient. Therefore, there is an urgent need for a device to solve these problems. Utility Model Content

The second gear is movably embedded on the outside of the support frame and meshes with the first gear. The motor is fixed to one side of the housing, and the rotating shaft is fixed at the output end of the motor and to one side of the first gear. When in use, the motor is started, and the motor drives the rotating shaft to rotate, which in turn drives the first gear to rotate, and so on, driving the second gear to rotate, thereby driving the adjacent first gears to rotate, so that all the first gears rotate, driving all the conveyor rollers to rotate, thus performing the transportation work. Only one power source is needed, which greatly facilitates subsequent maintenance work.
