Cnc Coiling Spring Machine

One or several pairs of rollers are used to press and rotate the steel wire to push the steel wire forward, and rely on the limiting and guiding action of the upper and lower ring diameter rods to form the steel wire. The steel wire continuously moves forward in the respective chutes of the upper and lower coil diameter rods, and the size of the spring coil diameter can be controlled by controlling the positions of the upper and lower coil diameter rods. The pitch rod is a movement perpendicular to the paper surface, and its function is to make the coiled steel wire form a thread lift angle; by controlling and adjusting the position of the pitch rod, the size of the spring pitch can be controlled. When the winding is completed, the wire is cut with a cutter.

Computer compression spring machine product series: mainly for circular, arc and straight spring products, such as various precision machining compression springs, tower springs, conical springs, skeleton seal springs and mold springs, etc., the forming rate is faster , high accuracy and high reliability.
All-round CNC spring machine product series: mainly for wire forming products of circles, arcs, straight lines and blank holders, such as various precision machining compression springs, tension springs, torsion springs, leaf springs, special-shaped springs and wire forming products .
Product series of CNC spring machine without camshaft turning line: CNC spring machine without camshaft turning line is in the development trend of most of the all-round CNC spring machine. It adopts unusual design without camshaft and arm without turning arm, which reduces the adjustment Difficulty, reduce the time to adjust the machine and equipment, and improve the expected effect of the work, but the higher price and cost make customers discouraged.

There are many types of springs, such as compression springs, tension springs, torsion springs, etc. Here we only introduce the working principle of the most widely used spring coiling machine.
A pair or several pairs of rollers are used to press and rotate the steel wire, push the steel wire to move to the right, and rely on the limiting and guiding action of the upper and lower ring diameter rods to form the steel wire. The upper and lower coil diameter rods can be moved in their respective chutes, and the size of the spring coil diameter can be controlled by controlling the positions of the upper and lower coil diameter rods. The pitch rod is a movement perpendicular to the paper surface, and its function is to make the coiled steel wire form a thread lift angle. By controlling the position of the pitch rod, the size of the spring pitch can be controlled. When the winding is complete, the wire is cut with a cutter. The core sleeve is used as a support when the cutter cuts the steel wire. Through the combined movement of the wire feed roller, the upper and lower ring diameter rods, the pitch rod and the cutter, circular compression springs of various shapes such as variable ring diameter and variable pitch can be wound. For the mechanical spring coiling machine, because there is only one power, each action lever is completely linked by gears, cams, clutches and other mechanisms, the structure is complex, and the adjustment is time-consuming. Every time a variety is replaced, the shape of the cam often needs to be trimmed, which requires a high technical level of the operator. In particular, the adjustment range of the wire feed length depends on the size of a sector gear, which limits the extension of the spring. When the sector gear goes back, it is necessary to use the clutch to disengage the wire feeding roller, which not only increases the noise, but also reduces the wire feeding accuracy.

 In order to be suitable for computer control, we have completely reformed the mechanical structure of the coiling machine. First of all, each moving mechanism is independent, and each is controlled by a servo motor. For example, the wire feeding mechanism is only a simple gear transmission, and the wire feeding length can be unlimited. ;The upper and lower ring diameter rods and pitch rods are directly driven by the motor connected to the ball screw; the cutting mechanism is only a simple cam drive, in addition to the general cutting method, it can also match the upper and lower cutters for twist cutting, In order to solve the spring shearing of large wire diameter and small winding ratio.
