Introduction to the Five Basic Structures and Functions of Spring Machines

Spring machine is currently very efficient spring processing automation equipment, but many users are not clear about the principle of spring machine processing. In order to let everyone better use the spring machine equipment, MYT will introduce the five basic structures and functions of the spring machine. The spring machine can process spring wire into various spring products, mainly relying on the five basic structural parts of straightening mechanism, feeding mechanism, reducing mechanism, pitch control mechanism and cutting mechanism. Different mechanisms are responsible for their respective functional parts.


Ⅰ. Spring machine straightening mechanism


The position of the straightening mechanism is between the material rack and the feeding roller. It consists of two sets of straightening rollers. The purpose of the straightening system is to eliminate the original bending deformation of the steel wire. The spring wire can be straightened into the shape after straightening. Mechanically, this is helpful for the spring machine to improve the precision of the coiled spring.


Ⅱ. Feeding mechanism of spring machine


This is a device used by the spring machine to transport the spring wire. It relies on a pair or two pairs of feed wheels to compress the steel wire. It uses a sector-shaped incomplete gear to drive the gears on the feed wheel shaft. The rotation of the feed wheel drives the steel wire to move forward. The length is the shaft length of the feeding wheel, and the expansion length of the spring can be determined by the number of rotations of the feeding wheel.


Ⅲ. Spring machine reducing mechanism


It is the control mechanism of the spring outer diameter when the spring is wound. The device is composed of two ejector rods and a reducing cam that drives the ejector rod. When the spring machine produces reduced diameter springs, such as convex, truncated cone springs, and upper ejector bars The front and rear two bolts are loosened, allowing the ejector rod to expand and contract back and forth in the tool holder to change the outer diameter of the spring. The ejector rod is driven by the diameter-reducing cam to achieve the purpose of producing various diameter-reducing springs.


Ⅳ. Pitch changing mechanism of spring machine


It is a mechanism that controls the pitch of the spring. Generally, there are two mechanisms for a spring machine. One is composed of a pitch knife and a variable-pitch cam. The variable cam is to control the effective number of turns of the spring, and the bolt under the pitch knife adjusts the height of the spring; the second is the cam driving the connecting rod to push the pitch knife out of the machine to better increase the pitch of the spring.


Ⅴ. Spring machine cutting mechanism


After winding and forming, cutting the steel wire is the last processing action for the spring to fall, and the spring cutting is completed by the knife and the core. This is the final processing structure of the spring processing.


The above are the five main structures for realizing automatic spring machining, which involve all the stages of straightening, wire feeding, diameter reduction, pitch, and cutting of the spring processing process. The technology and quality of the main structure will also affect the spring machine. Processing efficiency, performance and quality have a greater impact.
