Technical Field

[0001] The utility model relates to a strong pressure device, in particular to a spring strong pressure device, belonging to the technical field of spring strong pressure. Background Art

[0002] Currently, coiling and cold working during the spring manufacturing process can cause residual stress. When the residual stress in a spring is in the opposite direction of the working stress, it can increase the spring's load-bearing capacity; when the residual stress is in the same direction as the working stress, it can reduce the spring's load-bearing capacity. High-pressure (high-tension, high-torsion) treatment compresses the spring until the stress in the material layer exceeds the yield point, resulting in negative residual stress on the surface and positive residual stress in the core.

[0003] In actual use, there is a spring pressing device, which requires the staff to manually place the spring on the workbench, and then the cylinder pushes the punch down to press the spring to achieve the spring pressing treatment.
