摘要： According to an embodiment, a coil spring includes a wire rod (2) having an end and the other end. The wire rod (2) of the coil spring includes, with regard to a section of the wire rod (2), a round section potion (30) of an effective spring part (13), a square section portion (31) in which the section is substantially square, and a taper portion (32). The square section portion (31) includes an end turn part (11)(12). A length of each side of the section of the square section portion (31) is less than or equal to a square root of 1/2 multiplied by a diameter of the wire rod (2) of the round section portion (30). In the taper portion (32), from the round section portion (30) to the square section portion (31), the section changes from a round shape to substantially a square shape, and a sectional area is decreased.

摘要： A coiling machine (10) includes a material guide (12), first pin (13), second pin (14), pitch tool (15), cutting tool (16), heating device (17), temperature sensor (18), and controller. A material (2) continuously discharged from a tip (12a) of the material guide is bent between the first pin and the second pin to form an arc part (2a) between the first pin and the second pin. The controller select control data corresponding to the temperature of the material detected by the temperature sensor from a plurality of control data corresponding to a processing temperature. Then, the positions of the first pin and the second pin are controlled such that a radius of curvature of the arc part increases when the temperature of the material increases, and the position of the cutting tool is controlled such that a gap between the center of curvature (C1) of the arc part and the cutting tool increases.

摘要： A coiling machine (10) includes feed rollers (11a, 11b) for moving a wire (1), a wire guide (12), a first forming roller (13), a second forming roller (14), a pitch tool (21), a cutting mechanism (23), and a support mechanism (24) for supporting the wire (1). The cutting mechanism (23) includes a cutting rotor (22). The wire (1) coming out of the wire guide (12) is formed into a helical shape by the first forming roller (13), the second forming roller (14) and the pitch tool (21). After one coil spring of a predetermined length is formed, the wire (1) is cut by moving the cutting rotor (22) in the radial direction of the wire (1). The cutting rotor (22) cuts the wire (1) supported by the support mechanism (24) in the radial direction of the wire (1) between the second forming roller (14) and the pitch tool (21).
