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 spring forming device in which the steel wire can be continuously cut off without stopping the feeding of the steel wire in cutting, and in which the steel wire can be uniformly heated, is provided. The spring forming device has a wire supplying mechanism for supplying a steel wire using a plurality of feeding rollers, a heating mechanism for heating the steel wire, a coiling mechanism for forming in a coil state the heated steel wire, and a cutting mechanism for cutting the steel wire coiled at a given number of turns off the steel wire remained backward. A cutting blade of the cutting mechanism follows tracks having a speed Va that moves to the receiving blade and a speed Vc that moves in an axial direction of the coiled steel wire, in cutting of the steel wire.

摘要： A method produces helical springs by spring winding with a numerically controlled spring winding machine, a wire is fed, controlled by an NC control program, through a feed device to a forming device of the spring winding machine and is formed with the aid of tools in the forming device to form a helical spring. A measurement time is defined which occurs in a final phase of an overall manufacturing time for the helical spring at a time period before the end of the overall manufacturing time. A position of a spring end which is formed by an end surface of the wire is measured at this measurement time to determine an actual angle position of the spring end. A remaining distance for the wire feed is then calculated to achieve a nominal angle position of the spring end, as intended for the helical spring, at a reference time which occurs at a later time and the wire is fed through the remaining distance. The method allows the relative angle position of the spring ends of a helical spring to be set very precisely.
摘要翻译：一种方法通过用数控弹簧卷绕机的弹簧卷绕产生螺旋弹簧，由NC控制程序控制的导线通过进给装置进给到弹簧卷绕机的成形装置，并且借助于工具所述成形装置形成螺旋弹簧。定义测量时间，其在整个制造时间结束之前的时间段内发生在螺旋弹簧的总制造时间的最后阶段。在该测量时间测量由线的端面形成的弹簧端的位置，以确定弹簧端的实际角度位置。然后计算送丝的剩余距离，以便在稍后发生的参考时间实现弹簧端的标称角度位置，如针对螺旋弹簧的那样，并且导线通过剩余距离。该方法允许非常精确地设置螺旋弹簧的弹簧端部的相对角度位置。
