Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to an automatic stress-relieving device for compression springs. Background Technique

[0002] Stress-relieving treatment is a process method of compressing a spring until beneficial residual stress opposite to the working stress is generated on the surface layer of the spring material, so as to improve the load-bearing capacity of the spring and stabilize the geometric dimensions.

[0003] There is a existing spring stress-relieving machine (application number: 201921477234.X) that performs stress-relieving on a spring sleeved on a socket rod through a sliding mounting seat. The spring is not prone to breakage, improving the safety of operation. However, there are still problems. When performing stress-relieving work on the spring, the spring is sleeved on the outer wall of the rod body. When performing stress-relieving work on the spring through an external driving structure, the rod body can prevent the spring from deforming. Due to different production requirements, the sizes of springs are often different. When the size of the spring is much larger than the rod body, the spring is also prone to deformation during stress-relieving at this time. It is not convenient to replace the rod bodies of different sizes according to the size of the spring, and thus it is not convenient to perform stress-relieving work on springs of different sizes. Moreover, when performing stress-relieving on the spring, due to the different lengths of the springs, the above device needs to adjust the position of the mounting seat to tighten the shorter spring. At this time, the relative position between the mounting seat and the scale line changes, and it is rather troublesome for the staff to record, and thus it is not convenient to perform stress-relieving work on the shorter spring.
