What factors will affect the stability of the coil spring pitch of the spring machine?

1. The wire may cause unstable pitch. At present, the spring material in the market is mainly the application of cold drawn steel wire. Due to significant differences in the process level, technical process, and cost control adopted by various material suppliers, the quality and price of spring wire can vary greatly. Under the same conditions, using high-quality spring wire, Dongguan Spring Machine can demonstrate good stability; On the contrary, it is difficult to ensure stability of the spring products that are wound. It can be said that if the quality of the spring material used exceeds the standard, even with the best spring machine equipment, it is difficult to ensure the stability of the product. Therefore, the quality of the wire largely affects the instability of the spring pitch.

2. The pitch instability caused by the tooling mold. Tooling molds play a crucial role in the stable operation of spring machine equipment, especially molds with wire grooves, such as wire feeding rollers, wire plates, core rods, and curve gauges. The suppliers provide standard molds, and technical personnel perform secondary special processing such as deburring, chamfering, grinding, and making non-standard auxiliary molds when operating the computer spring press machine in conjunction with the needs of debugging the product. In addition to quality requirements (which determine the service life), tool molds also need to ensure smooth overall use and coordination (manually adjusted), in order to ensure the stability of the spring machine operation. Therefore, the reasons for tooling and molds can to some extent affect the instability of spring pitch.

3. The pitch may be unstable due to machine reasons. In addition to its quality, the "X-axis zero point running" of Dongguan spring machine is also one of the factors that causes unstable coil spring pitch. Among them, there are two types of X-axis origin movement, namely physical origin change and servo motor origin offset. For example, when the machine executes system commands, the starting (origin) position of the X-axis command changes, resulting in a constant total number of coils of the winding spring and a change in spring pitch, resulting in a longer or shorter total length. When there is an X-axis origin displacement, it is recommended to seek solutions from professionals or manufacturers. Therefore, in addition to the quality of the machine, the stability of the CNC spring machine itself can also lead to unstable spring pitch.
