Stamped Spring Design: Can it Work?

[CapitalClassi]

I've got a idea for a new product that would need a spring. The stamped spring would serve as a "bracket" for a .375 round steel bar. The stamped spring would be extruded and threaded for a 10-24,10-32 or 1/4 bolt. The round bar would have about .250 deflection with approximately 20lbs of force. Maximum of 35 lbs of force. Spring would be expected to handle hundreds of cycles daily. I added a print with the idea of what I had in mind. I know little about designing stamped springs. My question is basically could a stamped spring work? Would the spring be able to handle this much deflection with this amount of force? Would extruding and threading be the best option over riveting and welding?

Yes, a stamped spring could work for this application, depending on the material used. The choice between riveting and welding or extruding and threading would depend on what material is chosen. Different materials may have different strength characteristics that may make one option better than the other. It is important to select the right material for the application to make sure that the spring can handle the amount of deflection and force required.
