What is the working principle of computer helical spring machine？

The wire is extruded and rotated by one or several pairs of rollers, pushing the wire forward, and forming the wire through the limiting and guiding effects of the upper and lower ring rods. The steel wire is continuously advanced in the chute of the upper and lower annulus, and the size of the coil diameter can be controlled by controlling the position of the upper and lower annulus. The pitch bar is the vertical paper movement, its role is to form the thread Angle of the winding; The pitch of the spring can be controlled by controlling and adjusting the position of the pitch bar. After winding is completed, cut the wire with a cutter; Among them, the mandrel is used as a support for the cutting wire of the cutter.

The spring machine can wind cylindrical compression springs with different shapes such as variable ring diameter and variable pitch through the combination of wire roller, upper and lower ring diameter rod, pitch rod and tool. For the mechanical helical spring machine, because there is only one power mechanism, each action lever is completely linked by the gear, CAM, clutch and other working mechanisms, the structure is relatively complex, and the adjustment is time-consuming. Whenever the spring type is changed, it is usually necessary to trim the CAM shape. The technical level of the operator is relatively high, especially the adjustment range of the line length depends on the size of the sector gear, which limits the free length of the spring. When the unit gear returns, it is also necessary to remove the wire feed roller through the clutch, which not only increases the noise, but also reduces the wire feed accuracy during the winding process.
