Working principle of 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.

Customized Cnc Coiling Spring Machine

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.

Frequently Asked Question

Do you have any question?

For materials with different line diameters, the force applied by the tools during bending and cutting is different, which puts different strength and toughness requirements for the materials of the tool. For materials with larger diameter and high hardness of processing of 4.0 or 4.0mm, such as oil quenching steel, this requires higher the toughness and strength of the tools of the tool. At the same time, it is necessary to consider the angle of the tip of the knife, the smooth transition of the blade and the blade.As far as the safety of spring and the service life of the tools, the use of welding tungsten steel can solve this problem well. If it is easy to crack tungsten steel, it is not safe to splash on the workers. For line diameters below 1.0, lines and wire wheels can be used tungsten steel.  

The camless spring machine adopts a unique camless rocker and no rocker arm design. The independent servo drives the arms, and the arm can be disassembled, which is gradually accepted and recognized by more and more users. Compared with the traditional spring machine with cams, the product can be easily formed at one time, reducing the difficulty of product debugging and improving production efficiency.YLSK no cam spring molding machine provides excellent performance and accuracy, and can provide high -speed molding for various wires, including thick or fine diameter, rectangular or soft metal. Our wire molding machine takes into account the rigorous challenges today. The friendly control of the operator allows them to prepare quickly.

1. Measure the wire diameter of your spring wire (understanding the diameter of the spring wire is very important, different line diameters will use different spring machines) 2.What kind of line diameter is the spring (such as twist springs, crushing spring, butterfly, alien, etc. Different springs will use different spring machines)3. Spring specifications (such as wire diameter, inner diameter, outer diameter, number of circles, active circles, spacing, feet length, angle, etc.)4. Based on the estimated daily output and monthly output, the purchased CNC spring machine needs to meet the daily production of the product.  The most important point of the CNC crushing machine type matching is: spring model, wire diameter, outer diameter, inner diameter, number of circles, etc. If a spring has several outer diameters, it is a multi -diameter spring, using a multi -axis spring machine. If it is a straight barrel -shaped spring, the two -axis crusher spring machine is used.
