What is the winding mechanism of spring coiling machine?

The winding mechanism of Spring Coiling Machine is one of its core components, which directly determines the forming quality and production efficiency of the spring. The design and working principle of the winding mechanism determine how it can accurately wind the wire into the shape of a spiral spring during the production process. The following will introduce the winding mechanism of the spring coiling machine in detail, including its components, working principle and its application in the production of different types of springs.

The winding mechanism is mainly composed of the following key components.
Spindle: The spindle is the core component of the winding mechanism. It is driven to rotate by a motor. The rotation speed and direction of the spindle directly affect the winding speed and forming effect of the spring. In CNC spring winding machines, the speed of the spindle is usually precisely controlled by the CNC system (CNC) to ensure that the winding process of the wire meets the design requirements.
Winding rod: The winding rod is a long and straight metal rod on which the wire is wound to form a spiral shape. The diameter and material of the winding rod vary according to the type and specification of the spring produced. For thicker springs, the winding rod needs to have higher strength and rigidity to withstand the pressure generated when the wire is wound.
Guides: Guides guide the wire into the correct position to ensure that the wire fits snugly on the winding rod during winding. The accuracy of the guides directly affects the number of turns, spacing and shape of the spring. Modern spring winding machines are usually equipped with high-precision guides, and some can even automatically adjust the guide angle as needed to accommodate the production of different types of springs.
Forming tools: Forming tools are used to further shape the spring after winding. Different types of springs require different forming tools, for example, compression springs may require flat ends, while tension springs may require hooks at both ends. Forming tools are usually installed at the end of the winding mechanism and can perform various specific treatments on the spring.
Cutting device: The cutting device is used to cut the wire from the winding rod after the spring is wound. The cutting device usually consists of a high-strength blade or shearing tool that can quickly and accurately complete the cutting operation. Some spring winding machines are also equipped with an automatic cutting function that can automatically cut the wire according to the preset length during the winding process, further improving production efficiency.

The working principle of the winding mechanism is based on the combination of mechanical movement and automatic control technology. Specifically, the wire is guided to the winding rod through the guide device, the spindle drives the winding rod to rotate, and the wire is wound on it to form a spiral shape. The CNC system controls the spindle speed and the position of the guide device according to the set parameters to ensure that each circle of wire can be wound evenly and form the required spring shape.

During the winding process, the accuracy of the guide device is crucial. It must ensure that the wire feed angle is correct and that the wire does not slip or deflect during winding, which is crucial for the control of the spring's coil pitch and diameter. The forming tool further processes the wound spring according to the type and design requirements of the spring to ensure that the end shape of the spring meets the design requirements.

The winding mechanism of the spring winding machine is a key component in the production of high-quality springs. By accurately controlling the feeding, winding and forming processes of the wire, the winding mechanism can produce springs that meet various design requirements. Whether it is a compression spring, a tension spring, or a torsion spring, the high precision and automation of the winding mechanism ensure the consistency and performance of the spring, thus playing an important role in a wide range of industrial applications.
