What is the working principle of CNC coiling machine?

The working principle of the CNC spring coiling machine: use one or several pairs of rollers to press the steel wire and rotate it, promote the steel wire to move forward, and rely on the limit and guiding effect of the upper and lower ring diameter rods to form the steel wire. The steel wire moves forward continuously in the respective chutes of the upper and lower ring rods, and the size of the spring coil diameter can be controlled by controlling the position of the upper and lower ring rods.

The pitch rod is the movement of the perpendicular paper surface, and its function is to make the winding steel wire form a thread rising angle; By controlling and adjusting the position of the pitch lever, the size of the spring pitch can be controlled. When the winding is completed, the steel wire is cut off with a cutter; Among them, the mandrel is used as a support when cutting the steel wire with the knife, and the working principle of the CNC coiling machine is as follows

The spring machine can be wound with variable circle diameter and pitch through the combination of wire feeding rollers, upper and lower ring diameter rods, pitch rods and cutting knives.

Cylindrical compression springs of various shapes. For the mechanical spring coiling machine, because there is only one power mechanism, each action rod is completely through the gears and cams.

and clutch and other working mechanisms to achieve linkage, its structure is relatively complex, and the adjustment is time-consuming. Whenever a spring variety is replaced, it is often necessary to trim the cam shape, and the technical level of the operator is relatively high, especially the adjustment range of the wire length depends on the size of a sector gear, which limits the free extension of the spring. When the gears of the house are returned, it is also necessary to disengage the wire feeding roller through the clutch, which not only increases the noise, but also reduces the wire feeding accuracy in the winding process.

The basic structure of the CNC spring machine and the principle of work

The CNC spring machine can be divided into five parts: straightening mechanism, feeding mechanism, reducing mechanism, pitch control mechanism, and cutting mechanism.

1. CNC spring machine straightening mechanism:

The position of the straightening mechanism is between the material rack and the feeding roller, it is composed of two groups of straightening rollers, the purpose of the straightening system is to eliminate the original bending deformation of the steel wire, after straightening, it can straighten into the forming machinery, so as to improve the accuracy of the coil spring.

2. Feeding mechanism of CNC spring machine:

The feeding mechanism is a device that relies on one or two pairs of feeding wheels to compress the steel wire, and drives the steel wire to advance in a straight line by the rotation of the feeding wheel. The gears on the feeding wheel shaft of the sector-shaped incomplete gear transmission are used to complete the slag, and the speed of the upper and lower rollers is the same, but the direction of rotation is opposite. The feeding wheel rotates for a week, the feeding length is the circumference and width of the feeding wheel, the length of the spring can be determined by the number of rotations of the feeding wheel, and the number of teeth of the sector-shaped incomplete gear is the number of rotations that control the feeding wheel (specific reference coefficient table).

3. CNC spring machine reducer mechanism:

The reducer refers to the control mechanism of the outer diameter of the spring when the spring is wound, which is composed of two push rods and a reducer cam that drives the push rod.

When producing cylindrical springs, the spring wire is unchanged, and the two push rods are adjusted to the corresponding position to conform to the outer diameter size of the spring, and then the position of the two push rods is fixed.

When producing reducing springs, such as convex, truncated conical springs, and the two bolts before and after the upper ejector bar are loosened, so that the ejector rod expands and contracts back and forth in the turret to change the outer diameter of the spring, and drives the ejector rod through the reducer cam to achieve the purpose of producing various reducer springs.

For different types of spring products, the parameter requirements are different. For example, some springs, mechanical and CNC spring machines can be made; However, some spring products can only be processed by CNC spring machine. I am the first manager of the spring machine, who has been engaged in the CNC spring machine industry for many years, and I will share with you the difference between mechanical spring machine and CNC spring machine:

1. Mechanical spring machine, also known as "soil cannon machine" or "soil machine", is mainly used for the production and processing of simple spring and coil forming products, which has the advantages of simple modeling, convenience and low cost. Generally speaking, the production efficiency of the soil machine is hundreds of times faster than that of manual work, due to the shortcomings of poor stability, low precision requirements and pass rate of the product, it has gradually faded out of the market stage; However, due to the low cost of the earth-moving machine, ranging from several thousand yuan to tens of thousands of yuan, it is still used in a few underdeveloped beams and places.

2. CNC spring machine, also known as computer spring machine, is a CNC spring machine with computer system and instruction programming, mainly to achieve intelligent operation, the whole process can be programmed and controlled by the computer system, reducing the cost of artificial labor, with the advantages of convenience, high efficiency, stability, high precision and low artificial strength, etc., is widely used in modern industrial production; Because its cost is more expensive than that of the soil machine, the number of slag usually ranges from tens of thousands of yuan to hundreds of thousands of yuan, which is also the main reason for restricting the development of some small spring processing enterprises (Manager Li, who created the spring machine.

The working principle of CNC coiling machine.

Use one or several pairs of rollers to press the steel wire and rotate, promote the steel wire to move to the right, and rely on the limiting and guiding effect of the upper and lower ring diameter rods to form the steel wire. The upper and lower ring rods can be moved in their respective chutes, and the size of the spring coil diameter can be controlled by controlling the position of the upper and lower ring rods. The pitch rod is the movement of the perpendicular paper surface, and its function is to make the winding steel wire form a thread rising angle;

By controlling the position of the pitch lever, the size of the spring pitch can be controlled. When the winding is complete, cut the wire with a cutter. The core sleeve is used as a support when the cutter cuts the wire.

Through the combined movement of the wire feeding roller, the upper and lower circle diameter rods, the pitch rod and the cutting knife, the circular compression spring of various shapes such as variable circle diameter and variable pitch can be wound. For the mechanical spring coiling machine, because there is only one power, each action rod is completely linked by gears, cams, clutches and other mechanisms, the structure is complex, and the adjustment is time-consuming. Each time a variety is replaced, it is often necessary to trim the cam shape, which requires a high technical level of the operator, especially the adjustment range of the feed length depends on the size of a sector gear, which limits the length of the spring.

When the sector gear is returned, the clutch needs to be disengaged from the wire feeding roller, which not only increases the noise, but also reduces the accuracy of the wire feeding.

Machine: low efficiency, poor accuracy, low price. Number: Opposite.
