Abstract
An apparatus for assembling coil springs together into a matrix of coil springs. The apparatus has workholders with respective grippers that receive and hold portions of end turns of respective coil springs, and a loader supporting the workholders for moving the workholders through a motion that transfers the respective coil springs from a conveyor to the apparatus. The coil assembling apparatus has, for each coil, a die set having a fixed die and a movable die. The movable die is connected to a drive via linkage. The drive is operable to move the movable die through a motion that maintains a planar die face of the movable die substantially parallel to a planar die face of the stationary die. The coil assembling apparatus is also operable to automatically assemble two rows of coil springs into a row of coaxial coil springs.
