Object of the Invention To provide a load characteristic adjustment system for use with a linear-spring forming apparatus for forming a conic spring, the system capable of adjusting the load characteristic of a conic spring formed by the apparatus in a simple manner and relieving physical burden of a worker setting up the apparatus Means for Solving Problems The load characteristics adjustment system has a linear material feeder for feeding a linear material; at least one spring forming tool arranged to face the linear material feeder and abutted against the linear material to coil the linear material; spiraling means for spiraling the linear material into a spiral; and coil diameter varying means for changing the diameter of the coiled linear material The load characteristic adjustment system controls the linear material feeder so as to feed the linear material at a regulated constant acceleration to adjust the load characteristic of the conical spring formed. |
