Description

Technical Field

[0001] The utility model relates to the technical field of spring washer production, in particular to an annealing device used for spring washer production. Background Art

[0002] Washers are parts placed between the connected parts and nuts. They are usually flat metal rings used to protect the surface of the connected parts from being scratched by the nuts and to disperse the pressure of the nuts on the connected parts. Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts that are frequently assembled and disassembled.

[0003] Spring washers need to be annealed during production to eliminate residual internal stress and prevent deformation and cracking. At present, spring washers are mostly annealed in mesh belt annealing furnaces. When the conveyor mesh belt drives the spring washers through the furnace body, the spring washers accumulate on the conveyor mesh belt, resulting in uneven heating of the bottom spring washers, which affects the annealing effect.
