With the emergence and popularization of CNC spring machines and computer spring machines, the shortcomings of mechanical spring equipment have gradually been exposed, mainly in the following aspects.
1.Feeding accuracy / length
In terms of power source, the wire feeding power of mechanical spring machines uses ordinary three-phase / single-phase motors, which is characterized by uncontrolled angles.
2.Electromagnetic clutch / one-way clutch
Due to the structure of the mechanical spring machine, it is necessary to install a brake device to ensure that the line feed is stopped immediately after the clutch is disengaged, but it cannot accurately do this and cause the accuracy to decline, and the clutch is often a machine damage.
3.Feeding and forming power are from the same motor
During the wire feeding process, the forming cam also runs continuously to form a cutting action, so the wire feeding length is also limited, and it is not possible to produce a long spring with special specifications.
Due to the simple structure and poor signal processing ability of mechanical spring machines, the spring and computer spring machines have made up for the lack of machinery, and can not make corresponding actions after problems in the production of racks, wires, and other factors. Good production of high precision spring products.
