<p>A device and method for forming an end of a coiled spring. The device has a pair of horizontally disposed parallel rollers (8), a core (22), a stoppe r (20) installed adjacent to the peripheral surface of the core (22) and ver tically moving and rotating integrally with the core (22), a clamping jig (2 4) installed so as to be approachable and separable from the core (22) and h olding a half-finished spring (30) in cooperation with the core (22), and a pusher (12) for pushing the half-finished spring (30) toward the stopper (20 ). In the method, a big tail part is formed at one end of the half-finished spring (30) when the axis of the core (22) is positioned between the axis of the half-finished spring (30) and the axes of the parallel rollers (8). To make the big tail part, a clamping part (2) rotates the half-finished spring (30) in its coiling direction about the axis while holding the spring (30) inside a triangle formed by the axes of the parallel rollers (8) and the axi s of the core (22).</p> |
