Established Fabrication Methods for Two- and Three-Wire Mesh Springs

摘要

Manufacturing procedures are established for the quantity production of two and three-wire mesh springs on production coilers. The mesh spring configuration is a comparatively new concept and is intended for impact loading applications. Necessary tooling and modifications to facilitate the coiling of mesh springs were determined and adapted to the coiler. In this project, the following two common spring materials were used: music wire QQ-W-470 and stainless steel QQ-W-423. A two-wire mesh spring and a three-wire mesh spring were designed to equivalent conditions of load, stress, and outside coil diameter, and prototype lots of these designs were fabricated. If the spring pitch equals 12.7mm or less, the mesh springs can be fabricated with good dimensional control. Also, if 1.5 to 2.0 coils are closed on each spring end, spring separation can be prevented. (Author)
