Proper manufacturing of torsion springs to specific tolerances can present unique problems for spring makers who are supplying furniture manufacturers. Our solution for one spring maker was to design and manufacture an exceptional machine that can form ASTM A401 chrome silicon wire in diameters from 0.250″ to 0.438″, into torsion springs with inner diameters ranging from 1.25″ to 3.00″. This Servo Torsion Spring Machine was manufactured entirely in-house and designed in 3-D with Solid Works. All programming development was also done in-house. A totally custom solution! The Spring Machine, with a footprint of 12 feet by 20 feet, was supplied with a powered wire uncoiler, a 2-axis wire straightener, pneumatic wire feeder, and a 2,000 PSI hydraulic power unit. Full operator and maintenance training was also provided to the customer.
Used for the manufacture of chair mechanism springs, the Spring Machine was supplied with a 1 year warranty up to 3,000 hours of running time as well as installation, training, and digital & print manuals. Our testing included the processing of multiple spring and endform designs to ensure that we were delivering a state-of-the-art, flexible system. By taking our customer’s unique specifications and utilizing 3-D design and simulations, we were able to produce a Spring Machine that optimizes their spring making operations.
