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?
