摘要： A coiling machine includes feed rollers for moving a wire, a wire guide, a first forming roller, a second forming roller, a pitch tool, a cutting mechanism, and a support mechanism for supporting the wire. The cutting mechanism includes a cutting rotor. The wire coming out of the wire guide is formed into a helical shape by the first forming roller, the second forming roller and the pitch tool. After one coil spring of a predetermined length is formed, the wire is cut by moving the cutting rotor in the radial direction of the wire. The cutting rotor cuts the wire supported by the support mechanism in the radial direction of the wire between the second forming roller and the pitch tool.

摘要： A method of manufacturing a coil spring and a coil spring manufacturing apparatus are provided that enable precise forming of a coil spring even when various kinds of wire rods are used as a wire rod. This is based on the premise that the wire material being fed out is serially pressed against a rotating roller outer circumferential surface to form the wire rod into a coil shape. Under this premise, as the wire rod is fed out, a rotating roller is rotationally driven by a rotary drive force of a servomotor such that a portion pressed against the wire rod on the rotating roller outer circumferential surface moves toward the advancing side of the wire rod.

摘要： A method for producing a flat spiral spring formed as an annular disk-shaped segment, wherein a strip-shaped material is supplied in a tangential alignment to the lateral surface of the drum such that a lateral wall which determines the thickness of the strip-shaped material rests against some sections of a contact surface on the lateral surface of the drum. The contact surface of the drum has a radius which substantially corresponds to an internal radius of the strip-shaped material, and at least one deflecting device is aligned at a distance to the drum such that the strip-shaped material is guided in a forced manner between the drum and the deflecting device, and the strip-shaped material is bent so as to follow the drum by means of the deflecting device.

摘要： A coil spring manufacturing device includes a mandrel around which a wire is wound, a feed mechanism which feeds the wire toward the mandrel, guide members which guide the wire, a chuck which fixes a distal end of the wire, and a clamp mechanism. The clamp mechanism sandwiches the wire from both sides before the distal end of the wire reaches the mandrel. Further, the clamp mechanism can be rotated about a fulcrum by rotation actuator, and can also be slid in a direction along an axis of the mandrel by sliding actuator. In a state in which the wire is sandwiched by the clamp mechanism, the clamp mechanism is rotated, and if necessary, is slid. Thereby, a bent portion for a negative pitch portion of a coil spring is formed at a part of the wire.
