Stress Relieving Procedures for Helical Compression Springs

reportActive / Technical Report | Accession Number: ADA013826 | Open PDF

Abstract:

Various stress relieving procedures for the manufacture of cold wound helical compression springs were investigated to determine the effect that the time interval between the coiling and stress relieving operations has on spring life. Production springs with indexes of 3 to 13 were fabricated from various materials. The springs were stress relieved at varying times after the coiling operation. The effect of the time interval between the coiling and stress relieving operations was determined by visual observation for crack initiation and by laboratory endurance tests. Analysis of the test data showed that the time interval between the two operations has no effect on the endurance properties of the materials that were investigated.
