The spring clip fastener uses the energy stored during elastic deformation to relieve mechanical vibration and impact. It works under long-term dynamic loads. In order to ensure its high reliability, the correct heat treatment process is a necessary condition for the production of qualified spring clips. It is very meaningful to study the production process of spring clip heat treatment.

[0003] In the prior art, railway spring clip fasteners are often annealed in conventional annealing furnaces. Since the existing conventional annealing furnaces are not equipped with special placement and conveying structures for railway spring clip fasteners, some railway spring clip fasteners are not annealed thoroughly due to unreasonable placement during the annealing stage, affecting the final product quality of the railway spring clip fasteners. In addition, since no corresponding preheating and discharging buffer structures are provided, the annealing temperature of the railway spring clip fasteners is slow and people are scalded during the discharging stage.

[0004] To this end, an annealing device for railway spring clip fasteners is proposed, which has the advantages of uniform annealing and convenient material loading and unloading, thereby solving the problems in the above-mentioned background technology. Utility Model Content
